+ * Atomic operations.
+ *
+ * IMPORTANT:
+ * If you are not an expert in concurrent lockless programming, you should
+ * only be using the atomic lock and reference counting functions in this
+ * file.  In all other cases you should be protecting your data structures
+ * with full mutexes.
+ *
+ * The list of "safe" functions to use are:
+ *  SDL_AtomicLock()
+ *  SDL_AtomicUnlock()
+ *  SDL_AtomicIncRef()
+ *  SDL_AtomicDecRef()
+ *
+ * Seriously, here be dragons!
+ * ^^^^^^^^^^^^^^^^^^^^^^^^^^^
+ *
+ * You can find out a little more about lockless programming and the
+ * subtle issues that can arise here:
+ * http://msdn.microsoft.com/en-us/library/ee418650%28v=vs.85%29.aspx
+ *
+ * There's also lots of good information here:
+ * http://www.1024cores.net/home/lock-free-algorithms
+ * http://preshing.com/
+ *
+ * These operations may or may not actually be implemented using
+ * processor specific atomic operations. When possible they are
+ * implemented as true processor specific atomic operations. When that
+ * is not possible the are implemented using locks that *do* use the
+ * available atomic operations.
+ *
+ * All of the atomic operations that modify memory are full memory barriers.

+* Please submit changes by sending them to the public Khronos Bugzilla

+* "Khronos (general)" component "Registry".
+*
+* A predefined template which fills in some of the bug fields can be

+*    http://www.khronos.org/registry/implementers_guide.pdf
+*
+* This file should be included as
+*        #include <KHR/khrplatform.h>
+* by Khronos client API header files that use its types and defines.
+*
+* The types in khrplatform.h should only be used to define API-specific types.
+*
+* Types defined in khrplatform.h:
+*    khronos_int8_t              signed   8  bit
+*    khronos_uint8_t             unsigned 8  bit

+*    khronos_uint64_t            unsigned 64 bit
+*    khronos_intptr_t            signed   same number of bits as a pointer
+*    khronos_uintptr_t           unsigned same number of bits as a pointer
+*    khronos_ssize_t             signed   size
+*    khronos_usize_t             unsigned size
+*    khronos_float_t             signed   32 bit floating point
+*    khronos_time_ns_t           unsigned 64 bit time in nanoseconds

+*    khronos_stime_nanoseconds_t signed time interval in nanoseconds
+*    khronos_boolean_enum_t      enumerated boolean type. This should
+*      only be used as a base type when a client API's boolean type is
+*      an enum. Client APIs which use an integer or other type for
+*      booleans cannot use this as the base type for their boolean.
+*
+* Tokens defined in khrplatform.h:
+*
+*    KHRONOS_FALSE, KHRONOS_TRUE Enumerated boolean false/true values.

+ *  \file SDL_haptic.h
+ *
+ *  \brief The SDL haptic subsystem allows you to control haptic (force feedback)
+ *         devices.
+ *
+ *  The basic usage is as follows:
+ *   - Initialize the subsystem (::SDL_INIT_HAPTIC).
+ *   - Open a haptic device.
+ *    - SDL_HapticOpen() to open from index.
+ *    - SDL_HapticOpenFromJoystick() to open from an existing joystick.
+ *   - Create an effect (::SDL_HapticEffect).
+ *   - Upload the effect with SDL_HapticNewEffect().
+ *   - Run the effect with SDL_HapticRunEffect().
+ *   - (optional) Free the effect with SDL_HapticDestroyEffect().
+ *   - Close the haptic device with SDL_HapticClose().
+ *
+ * \par Simple rumble example:
+ * \code
+ *    SDL_Haptic *haptic;
+ *
+ *    // Open the device
+ *    haptic = SDL_HapticOpen( 0 );
+ *    if (haptic == NULL)
+ *       return -1;
+ *
+ *    // Initialize simple rumble
+ *    if (SDL_HapticRumbleInit( haptic ) != 0)
+ *       return -1;
+ *
+ *    // Play effect at 50% strength for 2 seconds
+ *    if (SDL_HapticRumblePlay( haptic, 0.5, 2000 ) != 0)
+ *       return -1;
+ *    SDL_Delay( 2000 );
+ *
+ *    // Clean up
+ *    SDL_HapticClose( haptic );
+ * \endcode
+ *
+ * \par Complete example:
+ * \code
+ * int test_haptic( SDL_Joystick * joystick ) {
+ *    SDL_Haptic *haptic;
+ *    SDL_HapticEffect effect;
+ *    int effect_id;
+ *
+ *    // Open the device
+ *    haptic = SDL_HapticOpenFromJoystick( joystick );
+ *    if (haptic == NULL) return -1; // Most likely joystick isn't haptic
+ *
+ *    // See if it can do sine waves
+ *    if ((SDL_HapticQuery(haptic) & SDL_HAPTIC_SINE)==0) {
+ *       SDL_HapticClose(haptic); // No sine effect
+ *       return -1;
+ *    }
+ *
+ *    // Create the effect
+ *    memset( &effect, 0, sizeof(SDL_HapticEffect) ); // 0 is safe default
+ *    effect.type = SDL_HAPTIC_SINE;
+ *    effect.periodic.direction.type = SDL_HAPTIC_POLAR; // Polar coordinates
+ *    effect.periodic.direction.dir[0] = 18000; // Force comes from south
+ *    effect.periodic.period = 1000; // 1000 ms
+ *    effect.periodic.magnitude = 20000; // 20000/32767 strength
+ *    effect.periodic.length = 5000; // 5 seconds long
+ *    effect.periodic.attack_length = 1000; // Takes 1 second to get max strength
+ *    effect.periodic.fade_length = 1000; // Takes 1 second to fade away
+ *
+ *    // Upload the effect
+ *    effect_id = SDL_HapticNewEffect( haptic, &effect );
+ *
+ *    // Test the effect
+ *    SDL_HapticRunEffect( haptic, effect_id, 1 );
+ *    SDL_Delay( 5000); // Wait for the effect to finish
+ *
+ *    // We destroy the effect, although closing the device also does this
+ *    SDL_HapticDestroyEffect( haptic, effect_id );
+ *
+ *    // Close the device
+ *    SDL_HapticClose(haptic);

+ *  \brief Structure that represents a haptic direction.
+ *
+ *  This is the direction where the force comes from,
+ *  instead of the direction in which the force is exerted.
+ *
+ *  Directions can be specified by:
+ *   - ::SDL_HAPTIC_POLAR : Specified by polar coordinates.
+ *   - ::SDL_HAPTIC_CARTESIAN : Specified by cartesian coordinates.
+ *   - ::SDL_HAPTIC_SPHERICAL : Specified by spherical coordinates.
+ *
+ *  Cardinal directions of the haptic device are relative to the positioning
+ *  of the device.  North is considered to be away from the user.
+ *
+ *  The following diagram represents the cardinal directions:

+ *
+ *  If type is ::SDL_HAPTIC_POLAR, direction is encoded by hundredths of a
+ *  degree starting north and turning clockwise.  ::SDL_HAPTIC_POLAR only uses
+ *  the first \c dir parameter.  The cardinal directions would be:
+ *   - North: 0 (0 degrees)
+ *   - East: 9000 (90 degrees)
+ *   - South: 18000 (180 degrees)
+ *   - West: 27000 (270 degrees)
+ *
+ *  If type is ::SDL_HAPTIC_CARTESIAN, direction is encoded by three positions
+ *  (X axis, Y axis and Z axis (with 3 axes)).  ::SDL_HAPTIC_CARTESIAN uses
+ *  the first three \c dir parameters.  The cardinal directions would be:
+ *   - North:  0,-1, 0
+ *   - East:   1, 0, 0
+ *   - South:  0, 1, 0
+ *   - West:  -1, 0, 0
+ *
+ *  The Z axis represents the height of the effect if supported, otherwise
+ *  it's unused.  In cartesian encoding (1, 2) would be the same as (2, 4), you
+ *  can use any multiple you want, only the direction matters.
+ *
+ *  If type is ::SDL_HAPTIC_SPHERICAL, direction is encoded by two rotations.
+ *  The first two \c dir parameters are used.  The \c dir parameters are as
+ *  follows (all values are in hundredths of degrees):
+ *   - Degrees from (1, 0) rotated towards (0, 1).
+ *   - Degrees towards (0, 0, 1) (device needs at least 3 axes).
+ *
+ *
+ *  Example of force coming from the south with all encodings (force coming
+ *  from the south means the user will have to pull the stick to counteract):
+ *  \code
+ *  SDL_HapticDirection direction;
+ *
+ *  // Cartesian directions
+ *  direction.type = SDL_HAPTIC_CARTESIAN; // Using cartesian direction encoding.
+ *  direction.dir[0] = 0; // X position
+ *  direction.dir[1] = 1; // Y position
+ *  // Assuming the device has 2 axes, we don't need to specify third parameter.
+ *
+ *  // Polar directions
+ *  direction.type = SDL_HAPTIC_POLAR; // We'll be using polar direction encoding.
+ *  direction.dir[0] = 18000; // Polar only uses first parameter
+ *
+ *  // Spherical coordinates
+ *  direction.type = SDL_HAPTIC_SPHERICAL; // Spherical encoding
+ *  direction.dir[0] = 9000; // Since we only have two axes we don't need more parameters.

+ *
+ *  A periodic effect consists in a wave-shaped effect that repeats itself
+ *  over time.  The type determines the shape of the wave and the parameters
+ *  determine the dimensions of the wave.
+ *
+ *  Phase is given by hundredth of a degree meaning that giving the phase a value
+ *  of 9000 will displace it 25% of its period.  Here are sample values:
+ *   -     0: No phase displacement.
+ *   -  9000: Displaced 25% of its period.
+ *   - 18000: Displaced 50% of its period.
+ *   - 27000: Displaced 75% of its period.
+ *   - 36000: Displaced 100% of its period, same as 0, but 0 is preferred.

+/** \brief Allows back-button-press events on Windows Phone to be marked as handled
+ *
+ *  Windows Phone devices typically feature a Back button.  When pressed,
+ *  the OS will emit back-button-press events, which apps are expected to
+ *  handle in an appropriate manner.  If apps do not explicitly mark these
+ *  events as 'Handled', then the OS will invoke its default behavior for
+ *  unhandled back-button-press events, which on Windows Phone 8 and 8.1 is to
+ *  terminate the app (and attempt to switch to the previous app, or to the
+ *  device's home screen).
+ *
+ *  Setting the SDL_HINT_WINRT_HANDLE_BACK_BUTTON hint to "1" will cause SDL
+ *  to mark back-button-press events as Handled, if and when one is sent to
+ *  the app.
+ *
+ *  Internally, Windows Phone sends back button events as parameters to
+ *  special back-button-press callback functions.  Apps that need to respond
+ *  to back-button-press events are expected to register one or more
+ *  callback functions for such, shortly after being launched (during the
+ *  app's initialization phase).  After the back button is pressed, the OS
+ *  will invoke these callbacks.  If the app's callback(s) do not explicitly
+ *  mark the event as handled by the time they return, or if the app never
+ *  registers one of these callback, the OS will consider the event
+ *  un-handled, and it will apply its default back button behavior (terminate
+ *  the app).
+ *
+ *  SDL registers its own back-button-press callback with the Windows Phone
+ *  OS.  This callback will emit a pair of SDL key-press events (SDL_KEYDOWN
+ *  and SDL_KEYUP), each with a scancode of SDL_SCANCODE_AC_BACK, after which
+ *  it will check the contents of the hint, SDL_HINT_WINRT_HANDLE_BACK_BUTTON.
+ *  If the hint's value is set to "1", the back button event's Handled
+ *  property will get set to 'true'.  If the hint's value is set to something
+ *  else, or if it is unset, SDL will leave the event's Handled property
+ *  alone.  (By default, the OS sets this property to 'false', to note.)
+ *
+ *  SDL apps can either set SDL_HINT_WINRT_HANDLE_BACK_BUTTON well before a
+ *  back button is pressed, or can set it in direct-response to a back button
+ *  being pressed.
+ *
+ *  In order to get notified when a back button is pressed, SDL apps should
+ *  register a callback function with SDL_AddEventWatch(), and have it listen
+ *  for SDL_KEYDOWN events that have a scancode of SDL_SCANCODE_AC_BACK.
+ *  (Alternatively, SDL_KEYUP events can be listened-for.  Listening for
+ *  either event type is suitable.)  Any value of SDL_HINT_WINRT_HANDLE_BACK_BUTTON
+ *  set by such a callback, will be applied to the OS' current
+ *  back-button-press event.
+ *
+ *  More details on back button behavior in Windows Phone apps can be found
+ *  at the following page, on Microsoft's developer site:
+ *  http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj247550(v=vs.105).aspx

+ *  makes sense to drag them from somewhere else inside the window itself; for
+ *  example, one might have a borderless window that wants to be draggable
+ *  from any part, or simulate its own title bar, etc.
+ *
+ *  This function lets the app provide a callback that designates pieces of
+ *  a given window as special. This callback is run during event processing
+ *  if we need to tell the OS to treat a region of the window specially; the
+ *  use of this callback is known as "hit testing."
+ *
+ *  Mouse input may not be delivered to your application if it is within
+ *  a special area; the OS will often apply that input to moving the window or
+ *  resizing the window and not deliver it to the application.
+ *
+ *  Specifying NULL for a callback disables hit-testing. Hit-testing is
+ *  disabled by default.
+ *
+ *  Platforms that don't support this functionality will return -1
+ *  unconditionally, even if you're attempting to disable hit-testing.
+ *
+ *  Your callback may fire at any time, and its firing does not indicate any
+ *  specific behavior (for example, on Windows, this certainly might fire
+ *  when the OS is deciding whether to drag your window, but it fires for lots
+ *  of other reasons, too, some unrelated to anything you probably care about
+ *  _and when the mouse isn't actually at the location it is testing_).
+ *  Since this can fire at any time, you should try to keep your callback
+ *  efficient, devoid of allocations, etc.

+ *
+ *  If \a path is NULL SDL will use the value of the environment variable
+ *  \c SDL_VULKAN_LIBRARY, if set, otherwise it loads the default Vulkan
+ *  loader library.
+ *
+ *  This should be called after initializing the video driver, but before
+ *  creating any Vulkan windows. If no Vulkan loader library is loaded, the
+ *  default library will be loaded upon creation of the first Vulkan window.
+ *
+ *  \note It is fairly common for Vulkan applications to link with \a libvulkan
+ *        instead of explicitly loading it at run time. This will work with
+ *        SDL provided the application links to a dynamic library and both it
+ *        and SDL use the same search path.
+ *
+ *  \note If you specify a non-NULL \c path, an application should retrieve all
+ *        of the Vulkan functions it uses from the dynamic library using

+ *        the vkGetInstanceProcAddr address within all the mach-o images of
+ *        the current process. This is because it is fairly common for Vulkan
+ *        applications to link with libvulkan (and historically MoltenVK was
+ *        provided as a static library). If it is not found then, on macOS, SDL
+ *        will attempt to load \c vulkan.framework/vulkan, \c libvulkan.1.dylib,
+ *        \c MoltenVK.framework/MoltenVK and \c libMoltenVK.dylib in that order.
+ *        On iOS SDL will attempt to load \c libMoltenVK.dylib. Applications
+ *        using a dynamic framework or .dylib must ensure it is included in its
+ *        application bundle.
+ *
+ *  \note On non-Apple devices, application linking with a static libvulkan is
+ *        not supported. Either do not link to the Vulkan loader or link to a

+* by Khronos client API header files that use its types and defines.
+*
+* The types in khrplatform.h should only be used to define API-specific types.
+*
+* Types defined in khrplatform.h:
+*    khronos_int8_t              signed   8  bit
+*    khronos_uint8_t             unsigned 8  bit
+*    khronos_int16_t             signed   16 bit
+*    khronos_uint16_t            unsigned 16 bit
+*    khronos_int32_t             signed   32 bit
+*    khronos_uint32_t            unsigned 32 bit
+*    khronos_int64_t             signed   64 bit
+*    khronos_uint64_t            unsigned 64 bit
+*    khronos_intptr_t            signed   same number of bits as a pointer
+*    khronos_uintptr_t           unsigned same number of bits as a pointer
+*    khronos_ssize_t             signed   size
+*    khronos_usize_t             unsigned size
+*    khronos_float_t             signed   32 bit floating point
+*    khronos_time_ns_t           unsigned 64 bit time in nanoseconds
+*    khronos_utime_nanoseconds_t unsigned time interval or absolute time in
+*                                         nanoseconds
+*    khronos_stime_nanoseconds_t signed time interval in nanoseconds
+*    khronos_boolean_enum_t      enumerated boolean type. This should
+*      only be used as a base type when a client API's boolean type is
+*      an enum. Client APIs which use an integer or other type for
+*      booleans cannot use this as the base type for their boolean.
+*
+* Tokens defined in khrplatform.h:
+*
+*    KHRONOS_FALSE, KHRONOS_TRUE Enumerated boolean false/true values.
+*
+*    KHRONOS_SUPPORT_INT64 is 1 if 64 bit integers are supported; otherwise 0.

+ *  If type is ::SDL_HAPTIC_POLAR, direction is encoded by hundredths of a
+ *  degree starting north and turning clockwise.  ::SDL_HAPTIC_POLAR only uses
+ *  the first \c dir parameter.  The cardinal directions would be:
+ *   - North: 0 (0 degrees)
+ *   - East: 9000 (90 degrees)
+ *   - South: 18000 (180 degrees)
+ *   - West: 27000 (270 degrees)
+ *
+ *  If type is ::SDL_HAPTIC_CARTESIAN, direction is encoded by three positions
+ *  (X axis, Y axis and Z axis (with 3 axes)).  ::SDL_HAPTIC_CARTESIAN uses
+ *  the first three \c dir parameters.  The cardinal directions would be:
+ *   - North:  0,-1, 0
+ *   - East:   1, 0, 0
+ *   - South:  0, 1, 0
+ *   - West:  -1, 0, 0
+ *
+ *  The Z axis represents the height of the effect if supported, otherwise
+ *  it's unused.  In cartesian encoding (1, 2) would be the same as (2, 4), you
+ *  can use any multiple you want, only the direction matters.
+ *
+ *  If type is ::SDL_HAPTIC_SPHERICAL, direction is encoded by two rotations.
+ *  The first two \c dir parameters are used.  The \c dir parameters are as
+ *  follows (all values are in hundredths of degrees):

+ *   - Degrees towards (0, 0, 1) (device needs at least 3 axes).

+ *  Time values unless specified otherwise are in milliseconds.
+ *
+ *  You can also pass ::SDL_HAPTIC_INFINITY to length instead of a 0-32767
+ *  value.  Neither delay, interval, attack_length nor fade_length support
+ *  ::SDL_HAPTIC_INFINITY.  Fade will also not be used since effect never ends.
+ *
+ *  Additionally, the ::SDL_HAPTIC_RAMP effect does not support a duration of
+ *  ::SDL_HAPTIC_INFINITY.
+ *
+ *  Button triggers may not be supported on all devices, it is advised to not
+ *  use them if possible.  Buttons start at index 1 instead of index 0 like
+ *  the joystick.
+ *
+ *  If both attack_length and fade_level are 0, the envelope is not used,
+ *  otherwise both values are used.
+ *
+ *  Common parts:
+ *  \code
+ *  // Replay - All effects have this
+ *  Uint32 length;        // Duration of effect (ms).
+ *  Uint16 delay;         // Delay before starting effect.
+ *
+ *  // Trigger - All effects have this
+ *  Uint16 button;        // Button that triggers effect.
+ *  Uint16 interval;      // How soon before effect can be triggered again.
+ *
+ *  // Envelope - All effects except condition effects have this
+ *  Uint16 attack_length; // Duration of the attack (ms).
+ *  Uint16 attack_level;  // Level at the start of the attack.
+ *  Uint16 fade_length;   // Duration of the fade out (ms).
+ *  Uint16 fade_level;    // Level at the end of the fade.

+/** \brief Allows back-button-press events on Windows Phone to be marked as handled
+ *
+ *  Windows Phone devices typically feature a Back button.  When pressed,
+ *  the OS will emit back-button-press events, which apps are expected to
+ *  handle in an appropriate manner.  If apps do not explicitly mark these
+ *  events as 'Handled', then the OS will invoke its default behavior for
+ *  unhandled back-button-press events, which on Windows Phone 8 and 8.1 is to
+ *  terminate the app (and attempt to switch to the previous app, or to the
+ *  device's home screen).
+ *
+ *  Setting the SDL_HINT_WINRT_HANDLE_BACK_BUTTON hint to "1" will cause SDL
+ *  to mark back-button-press events as Handled, if and when one is sent to
+ *  the app.
+ *
+ *  Internally, Windows Phone sends back button events as parameters to
+ *  special back-button-press callback functions.  Apps that need to respond
+ *  to back-button-press events are expected to register one or more
+ *  callback functions for such, shortly after being launched (during the
+ *  app's initialization phase).  After the back button is pressed, the OS
+ *  will invoke these callbacks.  If the app's callback(s) do not explicitly
+ *  mark the event as handled by the time they return, or if the app never
+ *  registers one of these callback, the OS will consider the event
+ *  un-handled, and it will apply its default back button behavior (terminate
+ *  the app).
+ *
+ *  SDL registers its own back-button-press callback with the Windows Phone
+ *  OS.  This callback will emit a pair of SDL key-press events (SDL_KEYDOWN
+ *  and SDL_KEYUP), each with a scancode of SDL_SCANCODE_AC_BACK, after which
+ *  it will check the contents of the hint, SDL_HINT_WINRT_HANDLE_BACK_BUTTON.
+ *  If the hint's value is set to "1", the back button event's Handled
+ *  property will get set to 'true'.  If the hint's value is set to something
+ *  else, or if it is unset, SDL will leave the event's Handled property
+ *  alone.  (By default, the OS sets this property to 'false', to note.)
+ *
+ *  SDL apps can either set SDL_HINT_WINRT_HANDLE_BACK_BUTTON well before a
+ *  back button is pressed, or can set it in direct-response to a back button
+ *  being pressed.
+ *
+ *  In order to get notified when a back button is pressed, SDL apps should
+ *  register a callback function with SDL_AddEventWatch(), and have it listen
+ *  for SDL_KEYDOWN events that have a scancode of SDL_SCANCODE_AC_BACK.
+ *  (Alternatively, SDL_KEYUP events can be listened-for.  Listening for
+ *  either event type is suitable.)  Any value of SDL_HINT_WINRT_HANDLE_BACK_BUTTON
+ *  set by such a callback, will be applied to the OS' current
+ *  back-button-press event.
+ *
+ *  More details on back button behavior in Windows Phone apps can be found
+ *  at the following page, on Microsoft's developer site:
+ *  http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj247550(v=vs.105).aspx

+ *  Normally windows are dragged and resized by decorations provided by the
+ *  system window manager (a title bar, borders, etc), but for some apps, it
+ *  makes sense to drag them from somewhere else inside the window itself; for
+ *  example, one might have a borderless window that wants to be draggable
+ *  from any part, or simulate its own title bar, etc.
+ *
+ *  This function lets the app provide a callback that designates pieces of
+ *  a given window as special. This callback is run during event processing
+ *  if we need to tell the OS to treat a region of the window specially; the
+ *  use of this callback is known as "hit testing."
+ *
+ *  Mouse input may not be delivered to your application if it is within
+ *  a special area; the OS will often apply that input to moving the window or
+ *  resizing the window and not deliver it to the application.
+ *
+ *  Specifying NULL for a callback disables hit-testing. Hit-testing is
+ *  disabled by default.
+ *
+ *  Platforms that don't support this functionality will return -1
+ *  unconditionally, even if you're attempting to disable hit-testing.
+ *
+ *  Your callback may fire at any time, and its firing does not indicate any
+ *  specific behavior (for example, on Windows, this certainly might fire
+ *  when the OS is deciding whether to drag your window, but it fires for lots
+ *  of other reasons, too, some unrelated to anything you probably care about
+ *  _and when the mouse isn't actually at the location it is testing_).
+ *  Since this can fire at any time, you should try to keep your callback
+ *  efficient, devoid of allocations, etc.
+ *
+ *  \param window The window to set hit-testing on.
+ *  \param callback The callback to call when doing a hit-test.
+ *  \param callback_data An app-defined void pointer passed to the callback.
+ *  \return 0 on success, -1 on error (including unsupported).

+  If any of the operations are not provided then we must emulate some
+  of them. That means we need a nice implementation of spin locks
+  that avoids the "one big lock" problem. We use a vector of spin
+  locks and pick which one to use based on the address of the operand
+  of the function.
+
+  To generate the index of the lock we first shift by 3 bits to get
+  rid on the zero bits that result from 32 and 64 bit allignment of
+  data. We then mask off all but 5 bits and use those 5 bits as an
+  index into the table.
+
+  Picking the lock this way insures that accesses to the same data at
+  the same time will go to the same lock. OTOH, accesses to different
+  data have only a 1/32 chance of hitting the same lock. That should
+  pretty much eliminate the chances of several atomic operations on
+  different data from waiting on the same "big lock". If it isn't
+  then the table of locks can be expanded to a new size so long as
+  the new size is a power of two.

+/* __ieee754_log(x)
+ * Return the logrithm of x
+ *
+ * Method :
+ *   1. Argument Reduction: find k and f such that
+ *			x = 2^k * (1+f),
+ *	   where  sqrt(2)/2 < 1+f < sqrt(2) .
+ *
+ *   2. Approximation of log(1+f).
+ *	Let s = f/(2+f) ; based on log(1+f) = log(1+s) - log(1-s)
+ *		 = 2s + 2/3 s**3 + 2/5 s**5 + .....,
+ *	     	 = 2s + s*R
+ *      We use a special Reme algorithm on [0,0.1716] to generate
+ * 	a polynomial of degree 14 to approximate R The maximum error
+ *	of this polynomial approximation is bounded by 2**-58.45. In
+ *	other words,
+ *		        2      4      6      8      10      12      14
+ *	    R(z) ~ Lg1*s +Lg2*s +Lg3*s +Lg4*s +Lg5*s  +Lg6*s  +Lg7*s
+ *  	(the values of Lg1 to Lg7 are listed in the program)
+ *	and
+ *	    |      2          14          |     -58.45
+ *	    | Lg1*s +...+Lg7*s    -  R(z) | <= 2
+ *	    |                             |
+ *	Note that 2s = f - s*f = f - hfsq + s*hfsq, where hfsq = f*f/2.
+ *	In order to guarantee error in log below 1ulp, we compute log
+ *	by
+ *		log(1+f) = f - s*(f - R)	(if f is not too large)
+ *		log(1+f) = f - (hfsq - s*(hfsq+R)).	(better accuracy)
+ *
+ *	3. Finally,  log(x) = k*ln2 + log(1+f).
+ *			    = k*ln2_hi+(f-(hfsq-(s*(hfsq+R)+k*ln2_lo)))
+ *	   Here ln2 is split into two floating point number:
+ *			ln2_hi + ln2_lo,
+ *	   where n*ln2_hi is always exact for |n| < 2000.
+ *
+ * Special cases:
+ *	log(x) is NaN with signal if x < 0 (including -INF) ;
+ *	log(+INF) is +INF; log(0) is -INF with signal;
+ *	log(NaN) is that NaN with no signal.
+ *
+ * Accuracy:
+ *	according to an error analysis, the error is always less than
+ *	1 ulp (unit in the last place).
+ *
+ * Constants:
+ * The hexadecimal values are the intended ones for the following
+ * constants. The decimal values may be used, provided that the
+ * compiler will convert from decimal to binary accurately enough
+ * to produce the hexadecimal values shown.

+/* __ieee754_sqrt(x)
+ * Return correctly rounded sqrt.
+ *           ------------------------------------------
+ *	     |  Use the hardware sqrt if you have one |
+ *           ------------------------------------------
+ * Method:
+ *   Bit by bit method using integer arithmetic. (Slow, but portable)
+ *   1. Normalization
+ *	Scale x to y in [1,4) with even powers of 2:
+ *	find an integer k such that  1 <= (y=x*2^(2k)) < 4, then
+ *		sqrt(x) = 2^k * sqrt(y)
+ *   2. Bit by bit computation
+ *	Let q  = sqrt(y) truncated to i bit after binary point (q = 1),
+ *	     i							 0
+ *                                     i+1         2
+ *	    s  = 2*q , and	y  =  2   * ( y - q  ).		(1)
+ *	     i      i            i                 i
+ *
+ *	To compute q    from q , one checks whether
+ *		    i+1       i
+ *
+ *			      -(i+1) 2
+ *			(q + 2      ) <= y.			(2)
+ *     			  i
+ *							      -(i+1)
+ *	If (2) is false, then q   = q ; otherwise q   = q  + 2      .
+ *		 	       i+1   i             i+1   i
+ *
+ *	With some algebric manipulation, it is not difficult to see
+ *	that (2) is equivalent to
+ *                             -(i+1)
+ *			s  +  2       <= y			(3)
+ *			 i                i
+ *
+ *	The advantage of (3) is that s  and y  can be computed by
+ *				      i      i
+ *	the following recurrence formula:
+ *	    if (3) is false
+ *
+ *	    s     =  s  ,	y    = y   ;			(4)
+ *	     i+1      i		 i+1    i
+ *
+ *	    otherwise,
+ *                         -i                     -(i+1)
+ *	    s	  =  s  + 2  ,  y    = y  -  s  - 2  		(5)
+ *           i+1      i          i+1    i     i
+ *
+ *	One may easily use induction to prove (4) and (5).
+ *	Note. Since the left hand side of (3) contain only i+2 bits,
+ *	      it does not necessary to do a full (53-bit) comparison
+ *	      in (3).
+ *   3. Final rounding
+ *	After generating the 53 bits result, we compute one more bit.
+ *	Together with the remainder, we can decide whether the
+ *	result is exact, bigger than 1/2ulp, or less than 1/2ulp
+ *	(it will never equal to 1/2ulp).
+ *	The rounding mode can be detected by checking whether
+ *	huge + tiny is equal to huge, and whether huge - tiny is
+ *	equal to huge for some floating point number "huge" and "tiny".
+ *
+ * Special cases:
+ *	sqrt(+-0) = +-0 	... exact
+ *	sqrt(inf) = inf
+ *	sqrt(-ve) = NaN		... with invalid signal
+ *	sqrt(NaN) = NaN		... with invalid signal for signaling NaN
+ *
+ * Other methods : see the appended file at the end of the program below.

+Other methods  (use floating-point arithmetic)
+-------------
+(This is a copy of a drafted paper by Prof W. Kahan
+and K.C. Ng, written in May, 1986)
+
+	Two algorithms are given here to implement sqrt(x)
+	(IEEE double precision arithmetic) in software.
+	Both supply sqrt(x) correctly rounded. The first algorithm (in
+	Section A) uses newton iterations and involves four divisions.
+	The second one uses reciproot iterations to avoid division, but
+	requires more multiplications. Both algorithms need the ability
+	to chop results of arithmetic operations instead of round them,
+	and the INEXACT flag to indicate when an arithmetic operation
+	is executed exactly with no roundoff error, all part of the
+	standard (IEEE 754-1985). The ability to perform shift, add,
+	subtract and logical AND operations upon 32-bit words is needed
+	too, though not part of the standard.
+
+A.  sqrt(x) by Newton Iteration
+
+   (1)	Initial approximation
+
+	Let x0 and x1 be the leading and the trailing 32-bit words of
+	a floating point number x (in IEEE double format) respectively
+
+	    1    11		     52				  ...widths
+	   ------------------------------------------------------
+	x: |s|	  e     |	      f				|
+	   ------------------------------------------------------
+	      msb    lsb  msb				      lsb ...order
+
+
+	     ------------------------  	     ------------------------
+	x0:  |s|   e    |    f1     |	 x1: |          f2           |
+	     ------------------------  	     ------------------------
+
+	By performing shifts and subtracts on x0 and x1 (both regarded
+	as integers), we obtain an 8-bit approximation of sqrt(x) as
+	follows.
+
+		k  := (x0>>1) + 0x1ff80000;
+		y0 := k - T1[31&(k>>15)].	... y ~ sqrt(x) to 8 bits
+	Here k is a 32-bit integer and T1[] is an integer array containing
+	correction terms. Now magically the floating value of y (y's
+	leading 32-bit word is y0, the value of its trailing word is 0)
+	approximates sqrt(x) to almost 8-bit.
+
+	Value of T1:
+	static int T1[32]= {
+	0,	1024,	3062,	5746,	9193,	13348,	18162,	23592,
+	29598,	36145,	43202,	50740,	58733,	67158,	75992,	85215,
+	83599,	71378,	60428,	50647,	41945,	34246,	27478,	21581,
+	16499,	12183,	8588,	5674,	3403,	1742,	661,	130,};
+
+    (2)	Iterative refinement
+
+	Apply Heron's rule three times to y, we have y approximates
+	sqrt(x) to within 1 ulp (Unit in the Last Place):
+
+		y := (y+x/y)/2		... almost 17 sig. bits
+		y := (y+x/y)/2		... almost 35 sig. bits
+		y := y-(y-x/y)/2	... within 1 ulp
+
+
+	Remark 1.
+	    Another way to improve y to within 1 ulp is:
+
+		y := (y+x/y)		... almost 17 sig. bits to 2*sqrt(x)
+		y := y - 0x00100006	... almost 18 sig. bits to sqrt(x)
+
+				2
+			    (x-y )*y
+		y := y + 2* ----------	...within 1 ulp
+			       2
+			     3y  + x
+
+
+	This formula has one division fewer than the one above; however,
+	it requires more multiplications and additions. Also x must be
+	scaled in advance to avoid spurious overflow in evaluating the
+	expression 3y*y+x. Hence it is not recommended uless division
+	is slow. If division is very slow, then one should use the
+	reciproot algorithm given in section B.
+
+    (3) Final adjustment
+
+	By twiddling y's last bit it is possible to force y to be
+	correctly rounded according to the prevailing rounding mode
+	as follows. Let r and i be copies of the rounding mode and
+	inexact flag before entering the square root program. Also we
+	use the expression y+-ulp for the next representable floating
+	numbers (up and down) of y. Note that y+-ulp = either fixed
+	point y+-1, or multiply y by nextafter(1,+-inf) in chopped
+	mode.
+
+		I := FALSE;	... reset INEXACT flag I
+		R := RZ;	... set rounding mode to round-toward-zero
+		z := x/y;	... chopped quotient, possibly inexact
+		If(not I) then {	... if the quotient is exact
+		    if(z=y) {
+		        I := i;	 ... restore inexact flag
+		        R := r;  ... restore rounded mode
+		        return sqrt(x):=y.
+		    } else {
+			z := z - ulp;	... special rounding
+		    }
+		}
+		i := TRUE;		... sqrt(x) is inexact
+		If (r=RN) then z=z+ulp	... rounded-to-nearest
+		If (r=RP) then {	... round-toward-+inf
+		    y = y+ulp; z=z+ulp;
+		}
+		y := y+z;		... chopped sum
+		y0:=y0-0x00100000;	... y := y/2 is correctly rounded.
+	        I := i;	 		... restore inexact flag
+	        R := r;  		... restore rounded mode
+	        return sqrt(x):=y.
+
+    (4)	Special cases
+
+	Square root of +inf, +-0, or NaN is itself;
+	Square root of a negative number is NaN with invalid signal.
+
+
+B.  sqrt(x) by Reciproot Iteration
+
+   (1)	Initial approximation
+
+	Let x0 and x1 be the leading and the trailing 32-bit words of
+	a floating point number x (in IEEE double format) respectively
+	(see section A). By performing shifs and subtracts on x0 and y0,
+	we obtain a 7.8-bit approximation of 1/sqrt(x) as follows.
+
+	    k := 0x5fe80000 - (x0>>1);
+	    y0:= k - T2[63&(k>>14)].	... y ~ 1/sqrt(x) to 7.8 bits
+
+	Here k is a 32-bit integer and T2[] is an integer array
+	containing correction terms. Now magically the floating
+	value of y (y's leading 32-bit word is y0, the value of
+	its trailing word y1 is set to zero) approximates 1/sqrt(x)
+	to almost 7.8-bit.
+
+	Value of T2:
+	static int T2[64]= {
+	0x1500,	0x2ef8,	0x4d67,	0x6b02,	0x87be,	0xa395,	0xbe7a,	0xd866,
+	0xf14a,	0x1091b,0x11fcd,0x13552,0x14999,0x15c98,0x16e34,0x17e5f,
+	0x18d03,0x19a01,0x1a545,0x1ae8a,0x1b5c4,0x1bb01,0x1bfde,0x1c28d,
+	0x1c2de,0x1c0db,0x1ba73,0x1b11c,0x1a4b5,0x1953d,0x18266,0x16be0,
+	0x1683e,0x179d8,0x18a4d,0x19992,0x1a789,0x1b445,0x1bf61,0x1c989,
+	0x1d16d,0x1d77b,0x1dddf,0x1e2ad,0x1e5bf,0x1e6e8,0x1e654,0x1e3cd,
+	0x1df2a,0x1d635,0x1cb16,0x1be2c,0x1ae4e,0x19bde,0x1868e,0x16e2e,
+	0x1527f,0x1334a,0x11051,0xe951,	0xbe01,	0x8e0d,	0x5924,	0x1edd,};
+
+    (2)	Iterative refinement
+
+	Apply Reciproot iteration three times to y and multiply the
+	result by x to get an approximation z that matches sqrt(x)
+	to about 1 ulp. To be exact, we will have
+		-1ulp < sqrt(x)-z<1.0625ulp.
+
+	... set rounding mode to Round-to-nearest
+	   y := y*(1.5-0.5*x*y*y)	... almost 15 sig. bits to 1/sqrt(x)
+	   y := y*((1.5-2^-30)+0.5*x*y*y)... about 29 sig. bits to 1/sqrt(x)
+	... special arrangement for better accuracy
+	   z := x*y			... 29 bits to sqrt(x), with z*y<1
+	   z := z + 0.5*z*(1-z*y)	... about 1 ulp to sqrt(x)
+
+	Remark 2. The constant 1.5-2^-30 is chosen to bias the error so that
+	(a) the term z*y in the final iteration is always less than 1;
+	(b) the error in the final result is biased upward so that
+		-1 ulp < sqrt(x) - z < 1.0625 ulp
+	    instead of |sqrt(x)-z|<1.03125ulp.
+
+    (3)	Final adjustment
+
+	By twiddling y's last bit it is possible to force y to be
+	correctly rounded according to the prevailing rounding mode
+	as follows. Let r and i be copies of the rounding mode and
+	inexact flag before entering the square root program. Also we
+	use the expression y+-ulp for the next representable floating
+	numbers (up and down) of y. Note that y+-ulp = either fixed
+	point y+-1, or multiply y by nextafter(1,+-inf) in chopped
+	mode.
+
+	R := RZ;		... set rounding mode to round-toward-zero
+	switch(r) {
+	    case RN:		... round-to-nearest
+	       if(x<= z*(z-ulp)...chopped) z = z - ulp; else
+	       if(x<= z*(z+ulp)...chopped) z = z; else z = z+ulp;
+	       break;
+	    case RZ:case RM:	... round-to-zero or round-to--inf
+	       R:=RP;		... reset rounding mod to round-to-+inf
+	       if(x<z*z ... rounded up) z = z - ulp; else
+	       if(x>=(z+ulp)*(z+ulp) ...rounded up) z = z+ulp;
+	       break;
+	    case RP:		... round-to-+inf
+	       if(x>(z+ulp)*(z+ulp)...chopped) z = z+2*ulp; else
+	       if(x>z*z ...chopped) z = z+ulp;
+	       break;
+	}
+
+	Remark 3. The above comparisons can be done in fixed point. For
+	example, to compare x and w=z*z chopped, it suffices to compare
+	x1 and w1 (the trailing parts of x and w), regarding them as
+	two's complement integers.
+
+	...Is z an exact square root?
+	To determine whether z is an exact square root of x, let z1 be the
+	trailing part of z, and also let x0 and x1 be the leading and
+	trailing parts of x.
+
+	If ((z1&0x03ffffff)!=0)	... not exact if trailing 26 bits of z!=0
+	    I := 1;		... Raise Inexact flag: z is not exact
+	else {
+	    j := 1 - [(x0>>20)&1]	... j = logb(x) mod 2
+	    k := z1 >> 26;		... get z's 25-th and 26-th
+					    fraction bits
+	    I := i or (k&j) or ((k&(j+j+1))!=(x1&3));
+	}
+	R:= r		... restore rounded mode
+	return sqrt(x):=z.
+
+	If multiplication is cheaper then the foregoing red tape, the
+	Inexact flag can be evaluated by
+
+	    I := i;
+	    I := (z*z!=x) or I.
+
+	Note that z*z can overwrite I; this value must be sensed if it is
+	True.
+
+	Remark 4. If z*z = x exactly, then bit 25 to bit 0 of z1 must be
+	zero.
+
+		    --------------------
+		z1: |        f2        |
+		    --------------------
+		bit 31		   bit 0
+
+	Further more, bit 27 and 26 of z1, bit 0 and 1 of x1, and the odd
+	or even of logb(x) have the following relations:
+
+	-------------------------------------------------
+	bit 27,26 of z1		bit 1,0 of x1	logb(x)
+	-------------------------------------------------
+	00			00		odd and even
+	01			01		even
+	10			10		odd
+	10			00		even
+	11			01		even
+	-------------------------------------------------

+ * __kernel_rem_pio2(x,y,e0,nx,prec,ipio2)
+ * double x[],y[]; int e0,nx,prec; int ipio2[];
+ *
+ * __kernel_rem_pio2 return the last three digits of N with
+ *		y = x - N*pi/2
+ * so that |y| < pi/2.
+ *
+ * The method is to compute the integer (mod 8) and fraction parts of
+ * (2/pi)*x without doing the full multiplication. In general we
+ * skip the part of the product that are known to be a huge integer (
+ * more accurately, = 0 mod 8 ). Thus the number of operations are
+ * independent of the exponent of the input.
+ *
+ * (2/pi) is represented by an array of 24-bit integers in ipio2[].
+ *
+ * Input parameters:
+ * 	x[]	The input value (must be positive) is broken into nx
+ *		pieces of 24-bit integers in double precision format.
+ *		x[i] will be the i-th 24 bit of x. The scaled exponent
+ *		of x[0] is given in input parameter e0 (i.e., x[0]*2^e0
+ *		match x's up to 24 bits.
+ *
+ *		Example of breaking a double positive z into x[0]+x[1]+x[2]:
+ *			e0 = ilogb(z)-23
+ *			z  = scalbn(z,-e0)
+ *		for i = 0,1,2
+ *			x[i] = floor(z)
+ *			z    = (z-x[i])*2**24
+ *
+ *
+ *	y[]	ouput result in an array of double precision numbers.
+ *		The dimension of y[] is:
+ *			24-bit  precision	1
+ *			53-bit  precision	2
+ *			64-bit  precision	2
+ *			113-bit precision	3
+ *		The actual value is the sum of them. Thus for 113-bit
+ *		precison, one may have to do something like:
+ *
+ *		long double t,w,r_head, r_tail;
+ *		t = (long double)y[2] + (long double)y[1];
+ *		w = (long double)y[0];
+ *		r_head = t+w;
+ *		r_tail = w - (r_head - t);
+ *
+ *	e0	The exponent of x[0]
+ *
+ *	nx	dimension of x[]
+ *
+ *  	prec	an integer indicating the precision:
+ *			0	24  bits (single)
+ *			1	53  bits (double)
+ *			2	64  bits (extended)
+ *			3	113 bits (quad)
+ *
+ *	ipio2[]
+ *		integer array, contains the (24*i)-th to (24*i+23)-th
+ *		bit of 2/pi after binary point. The corresponding
+ *		floating value is
+ *
+ *			ipio2[i] * 2^(-24(i+1)).
+ *
+ * External function:
+ *	double scalbn(), floor();
+ *
+ *
+ * Here is the description of some local variables:
+ *
+ * 	jk	jk+1 is the initial number of terms of ipio2[] needed
+ *		in the computation. The recommended value is 2,3,4,
+ *		6 for single, double, extended,and quad.
+ *
+ * 	jz	local integer variable indicating the number of
+ *		terms of ipio2[] used.
+ *
+ *	jx	nx - 1
+ *
+ *	jv	index for pointing to the suitable ipio2[] for the
+ *		computation. In general, we want
+ *			( 2^e0*x[0] * ipio2[jv-1]*2^(-24jv) )/8
+ *		is an integer. Thus
+ *			e0-3-24*jv >= 0 or (e0-3)/24 >= jv
+ *		Hence jv = max(0,(e0-3)/24).
+ *
+ *	jp	jp+1 is the number of terms in PIo2[] needed, jp = jk.
+ *
+ * 	q[]	double array with integral value, representing the
+ *		24-bits chunk of the product of x and 2/pi.
+ *
+ *	q0	the corresponding exponent of q[0]. Note that the
+ *		exponent for q[i] would be q0-24*i.
+ *
+ *	PIo2[]	double precision array, obtained by cutting pi/2
+ *		into 24 bits chunks.
+ *
+ *	f[]	ipio2[] in floating point
+ *
+ *	iq[]	integer array by breaking up q[] in 24-bits chunk.
+ *
+ *	fq[]	final product of x*(2/pi) in fq[0],..,fq[jk]
+ *
+ *	ih	integer. If >0 it indicates q[] is >= 0.5, hence
+ *		it also indicates the *sign* of the result.

+
+* Version 2.8.3 Thu Sep 22 11:16:15 2005  Doug Lea  (dl at gee)
+
+   Note: There may be an updated version of this malloc obtainable at
+           ftp://gee.cs.oswego.edu/pub/misc/malloc.c
+         Check before installing!
+
+* Quickstart
+
+  This library is all in one file to simplify the most common usage:
+  ftp it, compile it (-O3), and link it into another program. All of
+  the compile-time options default to reasonable values for use on
+  most platforms.  You might later want to step through various
+  compile-time and dynamic tuning options.
+
+  For convenience, an include file for code using this malloc is at:
+     ftp://gee.cs.oswego.edu/pub/misc/malloc-2.8.3.h
+  You don't really need this .h file unless you call functions not
+  defined in your system include files.  The .h file contains only the
+  excerpts from this file needed for using this malloc on ANSI C/C++
+  systems, so long as you haven't changed compile-time options about
+  naming and tuning parameters.  If you do, then you can create your
+  own malloc.h that does include all settings by cutting at the point
+  indicated below. Note that you may already by default be using a C
+  library containing a malloc that is based on some version of this
+  malloc (for example in linux). You might still want to use the one
+  in this file to customize settings or to avoid overheads associated
+  with library versions.
+
+* Vital statistics:
+
+  Supported pointer/size_t representation:       4 or 8 bytes
+       size_t MUST be an unsigned type of the same width as
+       pointers. (If you are using an ancient system that declares
+       size_t as a signed type, or need it to be a different width
+       than pointers, you can use a previous release of this malloc
+       (e.g. 2.7.2) supporting these.)
+
+  Alignment:                                     8 bytes (default)
+       This suffices for nearly all current machines and C compilers.
+       However, you can define MALLOC_ALIGNMENT to be wider than this
+       if necessary (up to 128bytes), at the expense of using more space.
+
+  Minimum overhead per allocated chunk:   4 or  8 bytes (if 4byte sizes)
+                                          8 or 16 bytes (if 8byte sizes)
+       Each malloced chunk has a hidden word of overhead holding size
+       and status information, and additional cross-check word
+       if FOOTERS is defined.
+
+  Minimum allocated size: 4-byte ptrs:  16 bytes    (including overhead)
+                          8-byte ptrs:  32 bytes    (including overhead)
+
+       Even a request for zero bytes (i.e., malloc(0)) returns a
+       pointer to something of the minimum allocatable size.
+       The maximum overhead wastage (i.e., number of extra bytes
+       allocated than were requested in malloc) is less than or equal
+       to the minimum size, except for requests >= mmap_threshold that
+       are serviced via mmap(), where the worst case wastage is about
+       32 bytes plus the remainder from a system page (the minimal
+       mmap unit); typically 4096 or 8192 bytes.
+
+  Security: static-safe; optionally more or less
+       The "security" of malloc refers to the ability of malicious
+       code to accentuate the effects of errors (for example, freeing
+       space that is not currently malloc'ed or overwriting past the
+       ends of chunks) in code that calls malloc.  This malloc
+       guarantees not to modify any memory locations below the base of
+       heap, i.e., static variables, even in the presence of usage
+       errors.  The routines additionally detect most improper frees
+       and reallocs.  All this holds as long as the static bookkeeping
+       for malloc itself is not corrupted by some other means.  This
+       is only one aspect of security -- these checks do not, and
+       cannot, detect all possible programming errors.
+
+       If FOOTERS is defined nonzero, then each allocated chunk
+       carries an additional check word to verify that it was malloced
+       from its space.  These check words are the same within each
+       execution of a program using malloc, but differ across
+       executions, so externally crafted fake chunks cannot be
+       freed. This improves security by rejecting frees/reallocs that
+       could corrupt heap memory, in addition to the checks preventing
+       writes to statics that are always on.  This may further improve
+       security at the expense of time and space overhead.  (Note that
+       FOOTERS may also be worth using with MSPACES.)
+
+       By default detected errors cause the program to abort (calling
+       "abort()"). You can override this to instead proceed past
+       errors by defining PROCEED_ON_ERROR.  In this case, a bad free
+       has no effect, and a malloc that encounters a bad address
+       caused by user overwrites will ignore the bad address by
+       dropping pointers and indices to all known memory. This may
+       be appropriate for programs that should continue if at all
+       possible in the face of programming errors, although they may
+       run out of memory because dropped memory is never reclaimed.
+
+       If you don't like either of these options, you can define
+       CORRUPTION_ERROR_ACTION and USAGE_ERROR_ACTION to do anything
+       else. And if if you are sure that your program using malloc has
+       no errors or vulnerabilities, you can define INSECURE to 1,
+       which might (or might not) provide a small performance improvement.
+
+  Thread-safety: NOT thread-safe unless USE_LOCKS defined
+       When USE_LOCKS is defined, each public call to malloc, free,
+       etc is surrounded with either a pthread mutex or a win32
+       spinlock (depending on WIN32). This is not especially fast, and
+       can be a major bottleneck.  It is designed only to provide
+       minimal protection in concurrent environments, and to provide a
+       basis for extensions.  If you are using malloc in a concurrent
+       program, consider instead using ptmalloc, which is derived from
+       a version of this malloc. (See http://www.malloc.de).
+
+  System requirements: Any combination of MORECORE and/or MMAP/MUNMAP
+       This malloc can use unix sbrk or any emulation (invoked using
+       the CALL_MORECORE macro) and/or mmap/munmap or any emulation
+       (invoked using CALL_MMAP/CALL_MUNMAP) to get and release system
+       memory.  On most unix systems, it tends to work best if both
+       MORECORE and MMAP are enabled.  On Win32, it uses emulations
+       based on VirtualAlloc. It also uses common C library functions
+       like memset.
+
+  Compliance: I believe it is compliant with the Single Unix Specification
+       (See http://www.unix.org). Also SVID/XPG, ANSI C, and probably
+       others as well.
+
+* Overview of algorithms
+
+  This is not the fastest, most space-conserving, most portable, or
+  most tunable malloc ever written. However it is among the fastest
+  while also being among the most space-conserving, portable and
+  tunable.  Consistent balance across these factors results in a good
+  general-purpose allocator for malloc-intensive programs.
+
+  In most ways, this malloc is a best-fit allocator. Generally, it
+  chooses the best-fitting existing chunk for a request, with ties
+  broken in approximately least-recently-used order. (This strategy
+  normally maintains low fragmentation.) However, for requests less
+  than 256bytes, it deviates from best-fit when there is not an
+  exactly fitting available chunk by preferring to use space adjacent
+  to that used for the previous small request, as well as by breaking
+  ties in approximately most-recently-used order. (These enhance
+  locality of series of small allocations.)  And for very large requests
+  (>= 256Kb by default), it relies on system memory mapping
+  facilities, if supported.  (This helps avoid carrying around and
+  possibly fragmenting memory used only for large chunks.)
+
+  All operations (except malloc_stats and mallinfo) have execution
+  times that are bounded by a constant factor of the number of bits in
+  a size_t, not counting any clearing in calloc or copying in realloc,
+  or actions surrounding MORECORE and MMAP that have times
+  proportional to the number of non-contiguous regions returned by
+  system allocation routines, which is often just 1.
+
+  The implementation is not very modular and seriously overuses
+  macros. Perhaps someday all C compilers will do as good a job
+  inlining modular code as can now be done by brute-force expansion,
+  but now, enough of them seem not to.
+
+  Some compilers issue a lot of warnings about code that is
+  dead/unreachable only on some platforms, and also about intentional
+  uses of negation on unsigned types. All known cases of each can be
+  ignored.
+
+  For a longer but out of date high-level description, see
+     http://gee.cs.oswego.edu/dl/html/malloc.html
+
+* MSPACES
+  If MSPACES is defined, then in addition to malloc, free, etc.,
+  this file also defines mspace_malloc, mspace_free, etc. These
+  are versions of malloc routines that take an "mspace" argument
+  obtained using create_mspace, to control all internal bookkeeping.
+  If ONLY_MSPACES is defined, only these versions are compiled.
+  So if you would like to use this allocator for only some allocations,
+  and your system malloc for others, you can compile with
+  ONLY_MSPACES and then do something like...
+    static mspace mymspace = create_mspace(0,0); // for example
+    #define mymalloc(bytes)  mspace_malloc(mymspace, bytes)
+
+  (Note: If you only need one instance of an mspace, you can instead
+  use "USE_DL_PREFIX" to relabel the global malloc.)
+
+  You can similarly create thread-local allocators by storing
+  mspaces as thread-locals. For example:
+    static __thread mspace tlms = 0;
+    void*  tlmalloc(size_t bytes) {
+      if (tlms == 0) tlms = create_mspace(0, 0);
+      return mspace_malloc(tlms, bytes);
+    }
+    void  tlfree(void* mem) { mspace_free(tlms, mem); }
+
+  Unless FOOTERS is defined, each mspace is completely independent.
+  You cannot allocate from one and free to another (although
+  conformance is only weakly checked, so usage errors are not always
+  caught). If FOOTERS is defined, then each chunk carries around a tag
+  indicating its originating mspace, and frees are directed to their
+  originating spaces.
+
+ -------------------------  Compile-time options ---------------------------
+
+Be careful in setting #define values for numerical constants of type
+size_t. On some systems, literal values are not automatically extended
+to size_t precision unless they are explicitly casted.
+
+WIN32                    default: defined if _WIN32 defined
+  Defining WIN32 sets up defaults for MS environment and compilers.
+  Otherwise defaults are for unix.
+
+MALLOC_ALIGNMENT         default: (size_t)8
+  Controls the minimum alignment for malloc'ed chunks.  It must be a
+  power of two and at least 8, even on machines for which smaller
+  alignments would suffice. It may be defined as larger than this
+  though. Note however that code and data structures are optimized for
+  the case of 8-byte alignment.
+
+MSPACES                  default: 0 (false)
+  If true, compile in support for independent allocation spaces.
+  This is only supported if HAVE_MMAP is true.
+
+ONLY_MSPACES             default: 0 (false)
+  If true, only compile in mspace versions, not regular versions.
+
+USE_LOCKS                default: 0 (false)
+  Causes each call to each public routine to be surrounded with
+  pthread or WIN32 mutex lock/unlock. (If set true, this can be
+  overridden on a per-mspace basis for mspace versions.)
+
+FOOTERS                  default: 0
+  If true, provide extra checking and dispatching by placing
+  information in the footers of allocated chunks. This adds
+  space and time overhead.
+
+INSECURE                 default: 0
+  If true, omit checks for usage errors and heap space overwrites.
+
+USE_DL_PREFIX            default: NOT defined
+  Causes compiler to prefix all public routines with the string 'dl'.
+  This can be useful when you only want to use this malloc in one part
+  of a program, using your regular system malloc elsewhere.
+
+ABORT                    default: defined as abort()
+  Defines how to abort on failed checks.  On most systems, a failed
+  check cannot die with an "assert" or even print an informative
+  message, because the underlying print routines in turn call malloc,
+  which will fail again.  Generally, the best policy is to simply call
+  abort(). It's not very useful to do more than this because many
+  errors due to overwriting will show up as address faults (null, odd
+  addresses etc) rather than malloc-triggered checks, so will also
+  abort.  Also, most compilers know that abort() does not return, so
+  can better optimize code conditionally calling it.
+
+PROCEED_ON_ERROR           default: defined as 0 (false)
+  Controls whether detected bad addresses cause them to bypassed
+  rather than aborting. If set, detected bad arguments to free and
+  realloc are ignored. And all bookkeeping information is zeroed out
+  upon a detected overwrite of freed heap space, thus losing the
+  ability to ever return it from malloc again, but enabling the
+  application to proceed. If PROCEED_ON_ERROR is defined, the
+  static variable malloc_corruption_error_count is compiled in
+  and can be examined to see if errors have occurred. This option
+  generates slower code than the default abort policy.
+
+DEBUG                    default: NOT defined
+  The DEBUG setting is mainly intended for people trying to modify
+  this code or diagnose problems when porting to new platforms.
+  However, it may also be able to better isolate user errors than just
+  using runtime checks.  The assertions in the check routines spell
+  out in more detail the assumptions and invariants underlying the
+  algorithms.  The checking is fairly extensive, and will slow down
+  execution noticeably. Calling malloc_stats or mallinfo with DEBUG
+  set will attempt to check every non-mmapped allocated and free chunk
+  in the course of computing the summaries.
+
+ABORT_ON_ASSERT_FAILURE   default: defined as 1 (true)
+  Debugging assertion failures can be nearly impossible if your
+  version of the assert macro causes malloc to be called, which will
+  lead to a cascade of further failures, blowing the runtime stack.
+  ABORT_ON_ASSERT_FAILURE cause assertions failures to call abort(),
+  which will usually make debugging easier.
+
+MALLOC_FAILURE_ACTION     default: sets errno to ENOMEM, or no-op on win32
+  The action to take before "return 0" when malloc fails to be able to
+  return memory because there is none available.
+
+HAVE_MORECORE             default: 1 (true) unless win32 or ONLY_MSPACES
+  True if this system supports sbrk or an emulation of it.
+
+MORECORE                  default: sbrk
+  The name of the sbrk-style system routine to call to obtain more
+  memory.  See below for guidance on writing custom MORECORE
+  functions. The type of the argument to sbrk/MORECORE varies across
+  systems.  It cannot be size_t, because it supports negative
+  arguments, so it is normally the signed type of the same width as
+  size_t (sometimes declared as "intptr_t").  It doesn't much matter
+  though. Internally, we only call it with arguments less than half
+  the max value of a size_t, which should work across all reasonable
+  possibilities, although sometimes generating compiler warnings.  See
+  near the end of this file for guidelines for creating a custom
+  version of MORECORE.
+
+MORECORE_CONTIGUOUS       default: 1 (true)
+  If true, take advantage of fact that consecutive calls to MORECORE
+  with positive arguments always return contiguous increasing
+  addresses.  This is true of unix sbrk. It does not hurt too much to
+  set it true anyway, since malloc copes with non-contiguities.
+  Setting it false when definitely non-contiguous saves time
+  and possibly wasted space it would take to discover this though.
+
+MORECORE_CANNOT_TRIM      default: NOT defined
+  True if MORECORE cannot release space back to the system when given
+  negative arguments. This is generally necessary only if you are
+  using a hand-crafted MORECORE function that cannot handle negative
+  arguments.
+
+HAVE_MMAP                 default: 1 (true)
+  True if this system supports mmap or an emulation of it.  If so, and
+  HAVE_MORECORE is not true, MMAP is used for all system
+  allocation. If set and HAVE_MORECORE is true as well, MMAP is
+  primarily used to directly allocate very large blocks. It is also
+  used as a backup strategy in cases where MORECORE fails to provide
+  space from system. Note: A single call to MUNMAP is assumed to be
+  able to unmap memory that may have be allocated using multiple calls
+  to MMAP, so long as they are adjacent.
+
+HAVE_MREMAP               default: 1 on linux, else 0
+  If true realloc() uses mremap() to re-allocate large blocks and
+  extend or shrink allocation spaces.
+
+MMAP_CLEARS               default: 1 on unix
+  True if mmap clears memory so calloc doesn't need to. This is true
+  for standard unix mmap using /dev/zero.
+
+USE_BUILTIN_FFS            default: 0 (i.e., not used)
+  Causes malloc to use the builtin ffs() function to compute indices.
+  Some compilers may recognize and intrinsify ffs to be faster than the
+  supplied C version. Also, the case of x86 using gcc is special-cased
+  to an asm instruction, so is already as fast as it can be, and so
+  this setting has no effect. (On most x86s, the asm version is only
+  slightly faster than the C version.)
+
+malloc_getpagesize         default: derive from system includes, or 4096.
+  The system page size. To the extent possible, this malloc manages
+  memory from the system in page-size units.  This may be (and
+  usually is) a function rather than a constant. This is ignored
+  if WIN32, where page size is determined using getSystemInfo during
+  initialization.
+
+USE_DEV_RANDOM             default: 0 (i.e., not used)
+  Causes malloc to use /dev/random to initialize secure magic seed for
+  stamping footers. Otherwise, the current time is used.
+
+NO_MALLINFO                default: 0
+  If defined, don't compile "mallinfo". This can be a simple way
+  of dealing with mismatches between system declarations and
+  those in this file.
+
+MALLINFO_FIELD_TYPE        default: size_t
+  The type of the fields in the mallinfo struct. This was originally
+  defined as "int" in SVID etc, but is more usefully defined as
+  size_t. The value is used only if  HAVE_USR_INCLUDE_MALLOC_H is not set
+
+REALLOC_ZERO_BYTES_FREES    default: not defined
+  This should be set if a call to realloc with zero bytes should
+  be the same as a call to free. Some people think it should. Otherwise,
+  since this malloc returns a unique pointer for malloc(0), so does
+  realloc(p, 0).
+
+LACKS_UNISTD_H, LACKS_FCNTL_H, LACKS_SYS_PARAM_H, LACKS_SYS_MMAN_H
+LACKS_STRINGS_H, LACKS_STRING_H, LACKS_SYS_TYPES_H,  LACKS_ERRNO_H
+LACKS_STDLIB_H                default: NOT defined unless on WIN32
+  Define these if your system does not have these header files.
+  You might need to manually insert some of the declarations they provide.
+
+DEFAULT_GRANULARITY        default: page size if MORECORE_CONTIGUOUS,
+                                system_info.dwAllocationGranularity in WIN32,
+                                otherwise 64K.
+      Also settable using mallopt(M_GRANULARITY, x)
+  The unit for allocating and deallocating memory from the system.  On
+  most systems with contiguous MORECORE, there is no reason to
+  make this more than a page. However, systems with MMAP tend to
+  either require or encourage larger granularities.  You can increase
+  this value to prevent system allocation functions to be called so
+  often, especially if they are slow.  The value must be at least one
+  page and must be a power of two.  Setting to 0 causes initialization
+  to either page size or win32 region size.  (Note: In previous
+  versions of malloc, the equivalent of this option was called
+  "TOP_PAD")
+
+DEFAULT_TRIM_THRESHOLD    default: 2MB
+      Also settable using mallopt(M_TRIM_THRESHOLD, x)
+  The maximum amount of unused top-most memory to keep before
+  releasing via malloc_trim in free().  Automatic trimming is mainly
+  useful in long-lived programs using contiguous MORECORE.  Because
+  trimming via sbrk can be slow on some systems, and can sometimes be
+  wasteful (in cases where programs immediately afterward allocate
+  more large chunks) the value should be high enough so that your
+  overall system performance would improve by releasing this much
+  memory.  As a rough guide, you might set to a value close to the
+  average size of a process (program) running on your system.
+  Releasing this much memory would allow such a process to run in
+  memory.  Generally, it is worth tuning trim thresholds when a
+  program undergoes phases where several large chunks are allocated
+  and released in ways that can reuse each other's storage, perhaps
+  mixed with phases where there are no such chunks at all. The trim
+  value must be greater than page size to have any useful effect.  To
+  disable trimming completely, you can set to MAX_SIZE_T. Note that the trick
+  some people use of mallocing a huge space and then freeing it at
+  program startup, in an attempt to reserve system memory, doesn't
+  have the intended effect under automatic trimming, since that memory
+  will immediately be returned to the system.
+
+DEFAULT_MMAP_THRESHOLD       default: 256K
+      Also settable using mallopt(M_MMAP_THRESHOLD, x)
+  The request size threshold for using MMAP to directly service a
+  request. Requests of at least this size that cannot be allocated
+  using already-existing space will be serviced via mmap.  (If enough
+  normal freed space already exists it is used instead.)  Using mmap
+  segregates relatively large chunks of memory so that they can be
+  individually obtained and released from the host system. A request
+  serviced through mmap is never reused by any other request (at least
+  not directly; the system may just so happen to remap successive
+  requests to the same locations).  Segregating space in this way has
+  the benefits that: Mmapped space can always be individually released
+  back to the system, which helps keep the system level memory demands
+  of a long-lived program low.  Also, mapped memory doesn't become
+  `locked' between other chunks, as can happen with normally allocated
+  chunks, which means that even trimming via malloc_trim would not
+  release them.  However, it has the disadvantage that the space
+  cannot be reclaimed, consolidated, and then used to service later
+  requests, as happens with normal chunks.  The advantages of mmap
+  nearly always outweigh disadvantages for "large" chunks, but the
+  value of "large" may vary across systems.  The default is an
+  empirically derived value that works well in most systems. You can
+  disable mmap by setting to MAX_SIZE_T.

+  independent_calloc(size_t n_elements, size_t element_size, void* chunks[]);
+
+  independent_calloc is similar to calloc, but instead of returning a
+  single cleared space, it returns an array of pointers to n_elements
+  independent elements that can hold contents of size elem_size, each
+  of which starts out cleared, and can be independently freed,
+  realloc'ed etc. The elements are guaranteed to be adjacently
+  allocated (this is not guaranteed to occur with multiple callocs or
+  mallocs), which may also improve cache locality in some
+  applications.
+
+  The "chunks" argument is optional (i.e., may be null, which is
+  probably the most typical usage). If it is null, the returned array
+  is itself dynamically allocated and should also be freed when it is
+  no longer needed. Otherwise, the chunks array must be of at least
+  n_elements in length. It is filled in with the pointers to the
+  chunks.
+
+  In either case, independent_calloc returns this pointer array, or
+  null if the allocation failed.  If n_elements is zero and "chunks"
+  is null, it returns a chunk representing an array with zero elements
+  (which should be freed if not wanted).
+
+  Each element must be individually freed when it is no longer
+  needed. If you'd like to instead be able to free all at once, you
+  should instead use regular calloc and assign pointers into this
+  space to represent elements.  (In this case though, you cannot
+  independently free elements.)
+
+  independent_calloc simplifies and speeds up implementations of many
+  kinds of pools.  It may also be useful when constructing large data
+  structures that initially have a fixed number of fixed-sized nodes,
+  but the number is not known at compile time, and some of the nodes
+  may later need to be freed. For example:
+
+  struct Node { int item; struct Node* next; };
+
+  struct Node* build_list() {
+    struct Node** pool;
+    int n = read_number_of_nodes_needed();
+    if (n <= 0) return 0;

+  independent_comalloc(size_t n_elements, size_t sizes[], void* chunks[]);
+
+  independent_comalloc allocates, all at once, a set of n_elements
+  chunks with sizes indicated in the "sizes" array.    It returns
+  an array of pointers to these elements, each of which can be
+  independently freed, realloc'ed etc. The elements are guaranteed to
+  be adjacently allocated (this is not guaranteed to occur with
+  multiple callocs or mallocs), which may also improve cache locality
+  in some applications.
+
+  The "chunks" argument is optional (i.e., may be null). If it is null
+  the returned array is itself dynamically allocated and should also
+  be freed when it is no longer needed. Otherwise, the chunks array
+  must be of at least n_elements in length. It is filled in with the
+  pointers to the chunks.
+
+  In either case, independent_comalloc returns this pointer array, or
+  null if the allocation failed.  If n_elements is zero and chunks is
+  null, it returns a chunk representing an array with zero elements
+  (which should be freed if not wanted).
+
+  Each element must be individually freed when it is no longer
+  needed. If you'd like to instead be able to free all at once, you
+  should instead use a single regular malloc, and assign pointers at
+  particular offsets in the aggregate space. (In this case though, you
+  cannot independently free elements.)
+
+  independent_comallac differs from independent_calloc in that each
+  element may have a different size, and also that it does not
+  automatically clear elements.
+
+  independent_comalloc can be used to speed up allocation in cases
+  where several structs or objects must always be allocated at the
+  same time.  For example:
+
+  struct Head { ... }
+  struct Foot { ... }
+
+  void send_message(char* msg) {
+    int msglen = strlen(msg);
+    size_t sizes[3] = { sizeof(struct Head), msglen, sizeof(struct Foot) };
+    void* chunks[3];
+    if (independent_comalloc(3, sizes, chunks) == 0)
+      die();
+    struct Head* head = (struct Head*)(chunks[0]);
+    char*        body = (char*)(chunks[1]);
+    struct Foot* foot = (struct Foot*)(chunks[2]);
+    // ...
+  }
+
+  In general though, independent_comalloc is worth using only for
+  larger values of n_elements. For small values, you probably won't
+  detect enough difference from series of malloc calls to bother.
+
+  Overuse of independent_comalloc can increase overall memory usage,
+  since it cannot reuse existing noncontiguous small chunks that
+  might be available for some of the elements.

+  (The following includes lightly edited explanations by Colin Plumb.)
+
+  The malloc_chunk declaration below is misleading (but accurate and
+  necessary).  It declares a "view" into memory allowing access to
+  necessary fields at known offsets from a given base.
+
+  Chunks of memory are maintained using a `boundary tag' method as
+  originally described by Knuth.  (See the paper by Paul Wilson
+  ftp://ftp.cs.utexas.edu/pub/garbage/allocsrv.ps for a survey of such
+  techniques.)  Sizes of free chunks are stored both in the front of
+  each chunk and at the end.  This makes consolidating fragmented
+  chunks into bigger chunks fast.  The head fields also hold bits
+  representing whether chunks are free or in use.
+
+  Here are some pictures to make it clearer.  They are "exploded" to
+  show that the state of a chunk can be thought of as extending from
+  the high 31 bits of the head field of its header through the
+  prev_foot and PINUSE_BIT bit of the following chunk header.
+
+  A chunk that's in use looks like:
+
+   chunk-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+           | Size of previous chunk (if P = 1)                             |

+         +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |P|
+         | Size of this chunk                                         1| +-+

+         +-                                                             -+

+  Note that since we always merge adjacent free chunks, the chunks
+  adjacent to a free chunk must be in use.
+
+  Given a pointer to a chunk (which can be derived trivially from the
+  payload pointer) we can, in O(1) time, find out whether the adjacent
+  chunks are free, and if so, unlink them from the lists that they
+  are on and merge them with the current chunk.
+
+  Chunks always begin on even word boundaries, so the mem portion
+  (which is returned to the user) is also on an even word boundary, and
+  thus at least double-word aligned.
+
+  The P (PINUSE_BIT) bit, stored in the unused low-order bit of the
+  chunk size (which is always a multiple of two words), is an in-use
+  bit for the *previous* chunk.  If that bit is *clear*, then the
+  word before the current chunk size contains the previous chunk
+  size, and can be used to find the front of the previous chunk.
+  The very first chunk allocated always has this bit set, preventing
+  access to non-existent (or non-owned) memory. If pinuse is set for
+  any given chunk, then you CANNOT determine the size of the
+  previous chunk, and might even get a memory addressing fault when
+  trying to do so.
+
+  The C (CINUSE_BIT) bit, stored in the unused second-lowest bit of
+  the chunk size redundantly records whether the current chunk is
+  inuse. This redundancy enables usage checks within free and realloc,
+  and reduces indirection when freeing and consolidating chunks.
+
+  Each freshly allocated chunk must have both cinuse and pinuse set.
+  That is, each allocated chunk borders either a previously allocated
+  and still in-use chunk, or the base of its memory arena. This is
+  ensured by making all allocations from the the `lowest' part of any
+  found chunk.  Further, no free chunk physically borders another one,
+  so each free chunk is known to be preceded and followed by either
+  inuse chunks or the ends of memory.
+
+  Note that the `foot' of the current chunk is actually represented
+  as the prev_foot of the NEXT chunk. This makes it easier to
+  deal with alignments etc but can be very confusing when trying
+  to extend or adapt this code.
+
+  The exceptions to all this are
+
+     1. The special chunk `top' is the top-most available chunk (i.e.,
+        the one bordering the end of available memory). It is treated
+        specially.  Top is never included in any bin, is used only if
+        no other chunk is available, and is released back to the
+        system if it is very large (see M_TRIM_THRESHOLD).  In effect,
+        the top chunk is treated as larger (and thus less well
+        fitting) than any other available chunk.  The top chunk
+        doesn't update its trailing size field since there is no next
+        contiguous chunk that would have to index off it. However,
+        space is still allocated for it (TOP_FOOT_SIZE) to enable
+        separation or merging when space is extended.
+
+     3. Chunks allocated via mmap, which have the lowest-order bit
+        (IS_MMAPPED_BIT) set in their prev_foot fields, and do not set
+        PINUSE_BIT in their head fields.  Because they are allocated
+        one-by-one, each must carry its own prev_foot field, which is
+        also used to hold the offset this chunk has within its mmapped
+        region, which is needed to preserve alignment. Each mmapped
+        chunk is trailed by the first two fields of a fake next-chunk
+        for sake of usage checks.

+
+  Each tree holding treenodes is a tree of unique chunk sizes.  Chunks
+  of the same size are arranged in a circularly-linked list, with only
+  the oldest chunk (the next to be used, in our FIFO ordering)
+  actually in the tree.  (Tree members are distinguished by a non-null
+  parent pointer.)  If a chunk with the same size an an existing node
+  is inserted, it is linked off the existing node using pointers that
+  work in the same way as fd/bk pointers of small chunks.
+
+  Each tree contains a power of 2 sized range of chunk sizes (the
+  smallest is 0x100 <= x < 0x180), which is is divided in half at each
+  tree level, with the chunks in the smaller half of the range (0x100
+  <= x < 0x140 for the top nose) in the left subtree and the larger
+  half (0x140 <= x < 0x180) in the right subtree.  This is, of course,
+  done by inspecting individual bits.
+
+  Using these rules, each node's left subtree contains all smaller
+  sizes than its right subtree.  However, the node at the root of each
+  subtree has no particular ordering relationship to either.  (The
+  dividing line between the subtree sizes is based on trie relation.)
+  If we remove the last chunk of a given size from the interior of the
+  tree, we need to replace it with a leaf node.  The tree ordering
+  rules permit a node to be replaced by any leaf below it.
+
+  The smallest chunk in a tree (a common operation in a best-fit
+  allocator) can be found by walking a path to the leftmost leaf in
+  the tree.  Unlike a usual binary tree, where we follow left child

+/* ----------------------------- Segments -------------------------------- */
+
+/*
+  Each malloc space may include non-contiguous segments, held in a
+  list headed by an embedded malloc_segment record representing the
+  top-most space. Segments also include flags holding properties of
+  the space. Large chunks that are directly allocated by mmap are not
+  included in this list. They are instead independently created and
+  destroyed without otherwise keeping track of them.
+
+  Segment management mainly comes into play for spaces allocated by
+  MMAP.  Any call to MMAP might or might not return memory that is
+  adjacent to an existing segment.  MORECORE normally contiguously
+  extends the current space, so this space is almost always adjacent,
+  which is simpler and faster to deal with. (This is why MORECORE is
+  used preferentially to MMAP when both are available -- see
+  sys_alloc.)  When allocating using MMAP, we don't use any of the
+  hinting mechanisms (inconsistently) supported in various
+  implementations of unix mmap, or distinguish reserving from
+  committing memory. Instead, we just ask for space, and exploit
+  contiguity when we get it.  It is probably possible to do
+  better than this on some systems, but no general scheme seems
+  to be significantly better.
+
+  Management entails a simpler variant of the consolidation scheme
+  used for chunks to reduce fragmentation -- new adjacent memory is
+  normally prepended or appended to an existing segment. However,
+  there are limitations compared to chunk consolidation that mostly
+  reflect the fact that segment processing is relatively infrequent
+  (occurring only when getting memory from system) and that we
+  don't expect to have huge numbers of segments:
+
+  * Segments are not indexed, so traversal requires linear scans.  (It
+    would be possible to index these, but is not worth the extra
+    overhead and complexity for most programs on most platforms.)
+  * New segments are only appended to old ones when holding top-most
+    memory; if they cannot be prepended to others, they are held in
+    different segments.
+
+  Except for the top-most segment of an mstate, each segment record
+  is kept at the tail of its segment. Segments are added by pushing
+  segment records onto the list headed by &mstate.seg for the
+  containing mstate.
+
+  Segment flags control allocation/merge/deallocation policies:
+  * If EXTERN_BIT set, then we did not allocate this segment,
+    and so should not try to deallocate or merge with others.
+    (This currently holds only for the initial segment passed
+    into create_mspace_with_base.)
+  * If IS_MMAPPED_BIT set, the segment may be merged with
+    other surrounding mmapped segments and trimmed/de-allocated
+    using munmap.
+  * If neither bit is set, then the segment was obtained using
+    MORECORE so can be merged with surrounding MORECORE'd segments
+    and deallocated/trimmed using MORECORE with negative arguments.

+/* ---------------------------- malloc_state ----------------------------- */
+
+/*
+   A malloc_state holds all of the bookkeeping for a space.
+   The main fields are:
+
+  Top
+    The topmost chunk of the currently active segment. Its size is
+    cached in topsize.  The actual size of topmost space is
+    topsize+TOP_FOOT_SIZE, which includes space reserved for adding
+    fenceposts and segment records if necessary when getting more
+    space from the system.  The size at which to autotrim top is
+    cached from mparams in trim_check, except that it is disabled if
+    an autotrim fails.
+
+  Designated victim (dv)
+    This is the preferred chunk for servicing small requests that
+    don't have exact fits.  It is normally the chunk split off most
+    recently to service another small request.  Its size is cached in
+    dvsize. The link fields of this chunk are not maintained since it
+    is not kept in a bin.
+
+  SmallBins
+    An array of bin headers for free chunks.  These bins hold chunks
+    with sizes less than MIN_LARGE_SIZE bytes. Each bin contains
+    chunks of all the same size, spaced 8 bytes apart.  To simplify
+    use in double-linked lists, each bin header acts as a malloc_chunk
+    pointing to the real first node, if it exists (else pointing to
+    itself).  This avoids special-casing for headers.  But to avoid
+    waste, we allocate only the fd/bk pointers of bins, and then use
+    repositioning tricks to treat these as the fields of a chunk.
+
+  TreeBins
+    Treebins are pointers to the roots of trees holding a range of
+    sizes. There are 2 equally spaced treebins for each power of two
+    from TREE_SHIFT to TREE_SHIFT+16. The last bin holds anything
+    larger.
+
+  Bin maps
+    There is one bit map for small bins ("smallmap") and one for
+    treebins ("treemap).  Each bin sets its bit when non-empty, and
+    clears the bit when empty.  Bit operations are then used to avoid
+    bin-by-bin searching -- nearly all "search" is done without ever
+    looking at bins that won't be selected.  The bit maps
+    conservatively use 32 bits per map word, even if on 64bit system.
+    For a good description of some of the bit-based techniques used
+    here, see Henry S. Warren Jr's book "Hacker's Delight" (and
+    supplement at http://hackersdelight.org/). Many of these are
+    intended to reduce the branchiness of paths through malloc etc, as
+    well as to reduce the number of memory locations read or written.
+
+  Segments
+    A list of segments headed by an embedded malloc_segment record
+    representing the initial space.
+
+  Address check support
+    The least_addr field is the least address ever obtained from
+    MORECORE or MMAP. Attempted frees and reallocs of any address less
+    than this are trapped (unless INSECURE is defined).
+
+  Magic tag
+    A cross-check field that should always hold same value as mparams.magic.
+
+  Flags
+    Bits recording whether to use MMAP, locks, or contiguous MORECORE
+
+  Statistics
+    Each space keeps track of current and maximum system memory
+    obtained via MORECORE or MMAP.
+
+  Locking
+    If USE_LOCKS is defined, the "mutex" lock is acquired and released
+    around every public call using this mspace.

+/* -------------------- Alternative MORECORE functions ------------------- */
+
+/*
+  Guidelines for creating a custom version of MORECORE:
+
+  * For best performance, MORECORE should allocate in multiples of pagesize.
+  * MORECORE may allocate more memory than requested. (Or even less,
+      but this will usually result in a malloc failure.)
+  * MORECORE must not allocate memory when given argument zero, but
+      instead return one past the end address of memory from previous
+      nonzero call.
+  * For best performance, consecutive calls to MORECORE with positive
+      arguments should return increasing addresses, indicating that
+      space has been contiguously extended.
+  * Even though consecutive calls to MORECORE need not return contiguous
+      addresses, it must be OK for malloc'ed chunks to span multiple
+      regions in those cases where they do happen to be contiguous.
+  * MORECORE need not handle negative arguments -- it may instead
+      just return MFAIL when given negative arguments.
+      Negative arguments are always multiples of pagesize. MORECORE
+      must not misinterpret negative args as large positive unsigned
+      args. You can suppress all such calls from even occurring by defining
+      MORECORE_CANNOT_TRIM,
+
+  As an example alternative MORECORE, here is a custom allocator
+  kindly contributed for pre-OSX macOS.  It uses virtually but not
+  necessarily physically contiguous non-paged memory (locked in,
+  present and won't get swapped out).  You can use it by uncommenting
+  this section, adding some #includes, and setting up the appropriate
+  defines above:
+
+      #define MORECORE osMoreCore
+
+  There is also a shutdown routine that should somehow be called for
+  cleanup upon program exit.
+
+  #define MAX_POOL_ENTRIES 100
+  #define MINIMUM_MORECORE_SIZE  (64 * 1024U)
+  static int next_os_pool;

+/* -----------------------------------------------------------------------
+History:
+    V2.8.3 Thu Sep 22 11:16:32 2005  Doug Lea  (dl at gee)

+      * Use trees for large bins
+      * Support mspaces
+      * Use segments to unify sbrk-based and mmap-based system allocation,

+      * Use mmap as backup to sbrk
+      * Place all internal state in malloc_state

+
+    V2.6.6 Sun Dec  5 07:42:19 1999  Doug Lea  (dl at gee)
+      * return null for negative arguments
+      * Added Several WIN32 cleanups from Martin C. Fong <mcfong at yahoo.com>

+         * Cleanup header file inclusion for WIN32 platforms
+         * Cleanup code to avoid Microsoft Visual C++ compiler complaints
+         * Add 'USE_DL_PREFIX' to quickly allow co-existence with existing
+           memory allocation routines
+         * Set 'malloc_getpagesize' for WIN32 platforms (needs more work)
+         * Use 'assert' rather than 'ASSERT' in WIN32 code to conform to
+           usage of 'assert' in non-WIN32 code
+         * Improve WIN32 'sbrk()' emulation's 'findRegion()' routine to
+           avoid infinite loop
+      * Always call 'fREe()' rather than 'free()'
+
+    V2.6.5 Wed Jun 17 15:57:31 1998  Doug Lea  (dl at gee)
+      * Fixed ordering problem with boundary-stamping

+      * Added pvalloc, as recommended by H.J. Liu
+      * Added 64bit pointer support mainly from Wolfram Gloger
+      * Added anonymously donated WIN32 sbrk emulation
+      * Malloc, calloc, getpagesize: add optimizations from Raymond Nijssen
+      * malloc_extend_top: fix mask error that caused wastage after
+        foreign sbrks
+      * Add linux mremap support code from HJ Liu
+
+    V2.6.2 Tue Dec  5 06:52:55 1995  Doug Lea  (dl at gee)
+      * Integrated most documentation with the code.
+      * Add support for mmap, with help from
+        Wolfram Gloger (Gloger@lrz.uni-muenchen.de).
+      * Use last_remainder in more cases.
+      * Pack bins using idea from  colin@nyx10.cs.du.edu
+      * Use ordered bins instead of best-fit threshhold
+      * Eliminate block-local decls to simplify tracing and debugging.
+      * Support another case of realloc via move into top
+      * Fix error occuring when initial sbrk_base not word-aligned.
+      * Rely on page size for units instead of SBRK_UNIT to
+        avoid surprises about sbrk alignment conventions.
+      * Add mallinfo, mallopt. Thanks to Raymond Nijssen
+        (raymond@es.ele.tue.nl) for the suggestion.
+      * Add `pad' argument to malloc_trim and top_pad mallopt parameter.
+      * More precautions for cases where other routines call sbrk,
+        courtesy of Wolfram Gloger (Gloger@lrz.uni-muenchen.de).
+      * Added macros etc., allowing use in linux libc from
+        H.J. Lu (hjl@gnu.ai.mit.edu)
+      * Inverted this history list
+
+    V2.6.1 Sat Dec  2 14:10:57 1995  Doug Lea  (dl at gee)
+      * Re-tuned and fixed to behave more nicely with V2.6.0 changes.
+      * Removed all preallocation code since under current scheme
+        the work required to undo bad preallocations exceeds
+        the work saved in good cases for most test programs.
+      * No longer use return list or unconsolidated bins since
+        no scheme using them consistently outperforms those that don't
+        given above changes.
+      * Use best fit for very large chunks to prevent some worst-cases.
+      * Added some support for debugging
+
+    V2.6.0 Sat Nov  4 07:05:23 1995  Doug Lea  (dl at gee)
+      * Removed footers when chunks are in use. Thanks to

+      * Added malloc_trim, with help from Wolfram Gloger
+        (wmglo@Dent.MED.Uni-Muenchen.DE).
+
+    V2.5.3 Tue Apr 26 10:16:01 1994  Doug Lea  (dl at g)
+
+    V2.5.2 Tue Apr  5 16:20:40 1994  Doug Lea  (dl at g)
+      * realloc: try to expand in both directions
+      * malloc: swap order of clean-bin strategy;
+      * realloc: only conditionally expand backwards
+      * Try not to scavenge used bins
+      * Use bin counts as a guide to preallocation
+      * Occasionally bin return list chunks in first scan
+      * Add a few optimizations from colin@nyx10.cs.du.edu
+
+    V2.5.1 Sat Aug 14 15:40:43 1993  Doug Lea  (dl at g)
+      * faster bin computation & slightly different binning
+      * merged all consolidations to one part of malloc proper
+         (eliminating old malloc_find_space & malloc_clean_bin)
+      * Scan 2 returns chunks (not just 1)
+      * Propagate failure in realloc if malloc returns 0
+      * Add stuff to allow compilation on non-ANSI compilers
+          from kpv@research.att.com
+
+    V2.5 Sat Aug  7 07:41:59 1993  Doug Lea  (dl at g.oswego.edu)
+      * removed potential for odd address access in prev_chunk
+      * removed dependency on getpagesize.h
+      * misc cosmetics and a bit more internal documentation
+      * anticosmetics: mangled names in macros to evade debugger strangeness
+      * tested on sparc, hp-700, dec-mips, rs6000
+          with gcc & native cc (hp, dec only) allowing
+          Detlefs & Zorn comparison study (in SIGPLAN Notices.)
+
+    Trial version Fri Aug 28 13:14:29 1992  Doug Lea  (dl at g.oswego.edu)
+      * Based loosely on libg++-1.2X malloc. (It retains some of the overall
+         structure of old version,  but most details differ.)

+ *   - Explicit recursion, guaranteed not to overflow
+ *   - A few little wrinkles stolen from the GNU |qsort()|.

+ *     broad ideas.)
+ *   - separate code for non-aligned / aligned / word-size objects
+ *
+ * Earlier releases of this code used an idiosyncratic licence

+/* Some comments on the implementation.
+ * 1. When we finish partitioning the array into "low"
+ *    and "high", we forget entirely about short subarrays,
+ *    because they'll be done later by insertion sort.
+ *    Doing lots of little insertion sorts might be a win
+ *    on large datasets for locality-of-reference reasons,
+ *    but it makes the code much nastier and increases
+ *    bookkeeping overhead.
+ * 2. We always save the shorter and get to work on the
+ *    longer. This guarantees that every time we push
+ *    an item onto the stack its size is <= 1/2 of that
+ *    of its parent; so the stack can't need more than
+ *    log_2(max-array-size) entries.
+ * 3. We choose a pivot by looking at the first, last
+ *    and middle elements. We arrange them into order
+ *    because it's easy to do that in conjunction with
+ *    choosing the pivot, and it makes things a little
+ *    easier in the partitioning step. Anyway, the pivot
+ *    is the middle of these three. It's still possible
+ *    to construct datasets where the algorithm takes
+ *    time of order n^2, but it simply never happens in
+ *    practice.
+ * 3' Newsflash: On further investigation I find that
+ *    it's easy to construct datasets where median-of-3
+ *    simply isn't good enough. So on large-ish subarrays
+ *    we do a more sophisticated pivoting: we take three
+ *    sets of 3 elements, find their medians, and then
+ *    take the median of those.
+ * 4. We copy the pivot element to a separate place
+ *    because that way we can always do our comparisons
+ *    directly against a pointer to that separate place,
+ *    and don't have to wonder "did we move the pivot
+ *    element?". This makes the inner loop better.
+ * 5. It's possible to make the pivoting even more
+ *    reliable by looking at more candidates when n
+ *    is larger. (Taking this to its logical conclusion
+ *    results in a variant of quicksort that doesn't
+ *    have that n^2 worst case.) However, the overhead
+ *    from the extra bookkeeping means that it's just
+ *    not worth while.
+ * 6. This is pretty clean and portable code. Here are
+ *    all the potential portability pitfalls and problems
+ *    I know of:
+ *      - In one place (the insertion sort) I construct
+ *        a pointer that points just past the end of the
+ *        supplied array, and assume that (a) it won't
+ *        compare equal to any pointer within the array,
+ *        and (b) it will compare equal to a pointer
+ *        obtained by stepping off the end of the array.
+ *        These might fail on some segmented architectures.
+ *      - I assume that there are 8 bits in a |char| when
+ *        computing the size of stack needed. This would
+ *        fail on machines with 9-bit or 16-bit bytes.
+ *      - I assume that if |((int)base&(sizeof(int)-1))==0|
+ *        and |(size&(sizeof(int)-1))==0| then it's safe to
+ *        get at array elements via |int*|s, and that if
+ *        actually |size==sizeof(int)| as well then it's
+ *        safe to treat the elements as |int|s. This might
+ *        fail on systems that convert pointers to integers
+ *        in non-standard ways.
+ *      - I assume that |8*sizeof(size_t)<=INT_MAX|. This
+ *        would be false on a machine with 8-bit |char|s,
+ *        16-bit |int|s and 4096-bit |size_t|s. :-)

+ *
+ * Mattias Engdeg�rd (Yorick): Rewrite. New encoding format, encoder and
+ * decoder. Added per-surface alpha blitter. Added per-pixel alpha
+ * format, encoder and blitter.
+ *
+ * Many thanks to Xark and johns for hints, benchmarks and useful comments
+ * leading to this code.
+ *
+ * Welcome to Macro Mayhem.
+ */
+
+/*
+ * The encoding translates the image data to a stream of segments of the form
+ *
+ * <skip> <run> <data>
+ *
+ * where <skip> is the number of transparent pixels to skip,
+ *       <run>  is the number of opaque pixels to blit,
+ * and   <data> are the pixels themselves.
+ *
+ * This basic structure is used both for colorkeyed surfaces, used for simple
+ * binary transparency and for per-surface alpha blending, and for surfaces
+ * with per-pixel alpha. The details differ, however:
+ *
+ * Encoding of colorkeyed surfaces:
+ *
+ *   Encoded pixels always have the same format as the target surface.
+ *   <skip> and <run> are unsigned 8 bit integers, except for 32 bit depth
+ *   where they are 16 bit. This makes the pixel data aligned at all times.
+ *   Segments never wrap around from one scan line to the next.
+ *
+ *   The end of the sequence is marked by a zero <skip>,<run> pair at the *
+ *   beginning of a line.
+ *
+ * Encoding of surfaces with per-pixel alpha:
+ *
+ *   The sequence begins with a struct RLEDestFormat describing the target
+ *   pixel format, to provide reliable un-encoding.
+ *
+ *   Each scan line is encoded twice: First all completely opaque pixels,
+ *   encoded in the target format as described above, and then all
+ *   partially transparent (translucent) pixels (where 1 <= alpha <= 254),
+ *   in the following 32-bit format:
+ *
+ *   For 32-bit targets, each pixel has the target RGB format but with
+ *   the alpha value occupying the highest 8 bits. The <skip> and <run>
+ *   counts are 16 bit.
+ *
+ *   For 16-bit targets, each pixel has the target RGB format, but with
+ *   the middle component (usually green) shifted 16 steps to the left,
+ *   and the hole filled with the 5 most significant bits of the alpha value.

+ *  SDL-based application THINK it's got a working video driver, for

+ *  and also for use as a collection of stubs when porting SDL to a new
+ *  platform for which you haven't yet written a valid video driver.
+ *
+ * This is also a great way to determine bottlenecks: if you think that SDL

+ *  then see if your application runs faster without video overhead.
+ *
+ * Initial work by Ryan C. Gordon (icculus@icculus.org). A good portion
+ *  of this was cut-and-pasted from Stephane Peter's work in the AAlib
+ *  SDL video driver.  Renamed to "DUMMY" by Sam Lantinga.

+ *
+ * The types in khrplatform.h should only be used to define API-specific types.
+ *
+ * Types defined in khrplatform.h:
+ *    khronos_int8_t              signed   8  bit
+ *    khronos_uint8_t             unsigned 8  bit
+ *    khronos_int16_t             signed   16 bit
+ *    khronos_uint16_t            unsigned 16 bit
+ *    khronos_int32_t             signed   32 bit
+ *    khronos_uint32_t            unsigned 32 bit
+ *    khronos_int64_t             signed   64 bit
+ *    khronos_uint64_t            unsigned 64 bit
+ *    khronos_intptr_t            signed   same number of bits as a pointer
+ *    khronos_uintptr_t           unsigned same number of bits as a pointer
+ *    khronos_ssize_t             signed   size
+ *    khronos_usize_t             unsigned size
+ *    khronos_float_t             signed   32 bit floating point
+ *    khronos_time_ns_t           unsigned 64 bit time in nanoseconds

+ *    khronos_stime_nanoseconds_t signed time interval in nanoseconds
+ *    khronos_boolean_enum_t      enumerated boolean type. This should
+ *      only be used as a base type when a client API's boolean type is
+ *      an enum. Client APIs which use an integer or other type for
+ *      booleans cannot use this as the base type for their boolean.
+ *
+ * Tokens defined in khrplatform.h:
+ *
+ *    KHRONOS_FALSE, KHRONOS_TRUE Enumerated boolean false/true values.
+ *
+ *    KHRONOS_SUPPORT_INT64 is 1 if 64 bit integers are supported; otherwise 0.

+ Support for Wayland with QmlCompositor as Server
+================================================
+
+The Wayland video driver has support for some additional features when

+
+The files following headers have been
+generated from the Wayland XML Protocol Definition in QtWayland as follows:
+
+Clone QtWayland from Git:
+    http://qt.gitorious.org/qt/qtwayland/
+

+     *
+     * I've tried to make this more reasonable, but I've run in to a lot
+     * of nonsense.
+     *
+     * The original issue is the code was written in pixels and not
+     * dialog units (DLUs). All DialogBox functions use DLUs, which
+     * vary based on the selected font (yay).
+     *
+     * According to MSDN, the most reliable way to convert is via
+     * MapDialogUnits, which requires an HWND, which we don't have
+     * at time of template creation.
+     *
+     * We do however have:
+     *  The system font (DLU width 8 for me)
+     *  The font we select for the dialog (DLU width 6 for me)
+     *
+     * Based on experimentation, *neither* of these return the value
+     * actually used. Stepping in to MapDialogUnits(), the conversion
+     * is fairly clear, and uses 7 for me.
+     *
+     * As a result, some of this is hacky to ensure the sizing is
+     * somewhat correct.
+     *
+     * Honestly, a long term solution is to use CreateWindow, not CreateDialog.
+     *
+
+     *
+     * In order to get text dimensions we need to have a DC with the desired font.
+     * I'm assuming a dialog box in SDL is rare enough we can to the create.

+       SDL_GL_ExtensionSupported which in turn calls SDL_GL_GetProcAddress.
+       However SDL_GL_GetProcAddress will fail if the library is not
+       loaded; it checks for gl_config.driver_loaded > 0. To avoid this
+       test failing, increment driver_loaded around the call to
+       WIN_GLInitExtensions.
+
+       Successful loading of the library is normally indicated by
+       SDL_GL_LoadLibrary incrementing driver_loaded immediately after
+       this function returns 0 to it.
+
+       Alternatives to this are:
+       - moving SDL_GL_DeduceMaxSupportedESProfile to both the WIN and
+         X11 platforms while adding a function equivalent to
+         SDL_GL_ExtensionSupported but which directly calls
+         glGetProcAddress(). Having 3 copies of the
+         SDL_GL_ExtensionSupported makes this alternative unattractive.
+       - moving SDL_GL_DeduceMaxSupportedESProfile to a new file shared
+         by the WIN and X11 platforms while adding a function equivalent
+         to SDL_GL_ExtensionSupported. This is unattractive due to the
+         number of project files that will need updating, plus there
+         will be 2 copies of the SDL_GL_ExtensionSupported code.
+       - Add a private equivalent of SDL_GL_ExtensionSupported to
+         SDL_video.c.
+       - Move the call to WIN_GL_InitExtensions back to WIN_CreateWindow
+         and add a flag to gl_data to avoid multiple calls to this
+         expensive function. This is probably the least objectionable
+         alternative if this increment/decrement trick is unacceptable.
+
+       Note that the driver_loaded > 0 check needs to remain in
+       SDL_GL_ExtensionSupported and SDL_GL_GetProcAddress as they are
+       public API functions.

+        // There are two ways to hide a cursor in WinRT/UWP apps.
+        // Both involve setting the WinRT CoreWindow's (which is somewhat analogous

+        //
+        // The first way to hide a cursor sets PointerCursor to nullptr.  This
+        // is, arguably, the easiest to implement for an app.  It does have an
+        // unfortunate side-effect: it'll prevent mouse-motion events from being
+        // sent to the app (via CoreWindow).
+        //
+        // The second way to hide a cursor sets PointerCursor to a transparent
+        // cursor.  This allows mouse-motion events to be sent to the app, but is
+        // more difficult to set up, as:
+        //   1. WinRT/UWP, while providing a few stock cursors, does not provide
+        //      a completely transparent cursor.
+        //   2. WinRT/UWP allows apps to provide custom-built cursors, but *ONLY*
+        //      if they are linked directly inside the app, via Win32-style
+        //      cursor resource files.  APIs to create cursors at runtime are
+        //      not provided to apps, and attempting to link-to or use Win32
+        //      cursor-creation APIs could cause an app to fail Windows Store
+        //      certification.
+        //
+        // SDL can use either means of hiding the cursor.  It provides a Win32-style
+        // set of cursor resource files in its source distribution, inside
+        // src/main/winrt/.  If those files are linked to an SDL-for-WinRT/UWP app
+        // (by including them in a MSVC project, for example), SDL will attempt to
+        // use those, if and when the cursor is hidden via SDL APIs.  If those
+        // files are not linked in, SDL will attempt to hide the cursor via the
+        // 'set PointerCursor to nullptr' means (which, if you recall, causes
+        // mouse-motion data to NOT be sent to the app!).
+        //
+        // Tech notes:
+        //  - SDL's blank cursor resource uses a resource ID of 5000.
+        //  - SDL's cursor resources consist of the following two files:

+        //     - src/main/winrt/SDL2-WinRTResources.rc             -- declares the cursor resource, and its ID (of 5000)

+    // MouseDelta field often reports very large values.  More information
+    // on this can be found at the following pages on MSDN:
+    //  - http://social.msdn.microsoft.com/Forums/en-US/winappswithnativecode/thread/a3c789fa-f1c5-49c4-9c0a-7db88d0f90f8
+    //  - https://connect.microsoft.com/VisualStudio/Feedback/details/756515
+    //
+    // The values do not appear to be as large when running on some systems,
+    // most notably a Surface RT.  Furthermore, the values returned by
+    // CoreWindow's PointerMoved event, and sent to this class' OnPointerMoved
+    // method, do not ever appear to be large, even when MouseEventArgs'
+    // MouseDelta is reporting to the contrary.
+    //
+    // On systems with the large-values behavior, it appears that the values
+    // get reported as if the screen's size is 65536 units in both the X and Y
+    // dimensions.  This can be viewed by using Windows' now-private, "Raw Input"
+    // APIs.  (GetRawInputData, RegisterRawInputDevices, WM_INPUT, etc.)
+    //
+    // MSDN's documentation on MouseEventArgs' MouseDelta field (at
+    // http://msdn.microsoft.com/en-us/library/windows/apps/windows.devices.input.mouseeventargs.mousedelta ),
+    // does not seem to indicate (to me) that its values should be so large.  It
+    // says that its values should be a "change in screen location".  I could
+    // be misinterpreting this, however a post on MSDN from a Microsoft engineer (see:
+    // http://social.msdn.microsoft.com/Forums/en-US/winappswithnativecode/thread/09a9868e-95bb-4858-ba1a-cb4d2c298d62 ),
+    // indicates that these values are in DIPs, which is the same unit used
+    // by CoreWindow's PointerMoved events (via the Position field in its CurrentPoint
+    // property.  See http://msdn.microsoft.com/en-us/library/windows/apps/windows.ui.input.pointerpoint.position.aspx
+    // for details.)
+    //
+    // To note, PointerMoved events are sent a 'RawPosition' value (via the
+    // CurrentPoint property in MouseEventArgs), however these do not seem
+    // to exhibit the same large-value behavior.
+    //
+    // The values passed via PointerMoved events can't always be used for relative
+    // mouse motion, unfortunately.  Its values are bound to the cursor's position,
+    // which stops when it hits one of the screen's edges.  This can be a problem in
+    // first person shooters, whereby it is normal for mouse motion to travel far
+    // along any one axis for a period of time.  MouseMoved events do not have the
+    // screen-bounding limitation, and can be used regardless of where the system's
+    // cursor is.
+    //
+    // One possible workaround would be to programmatically set the cursor's
+    // position to the screen's center (when SDL's relative mouse mode is enabled),
+    // however WinRT does not yet seem to have the ability to set the cursor's
+    // position via a public API.  Win32 did this via an API call, SetCursorPos,
+    // however WinRT makes this function be private.  Apps that use it won't get
+    // approved for distribution in the Windows Store.  I've yet to be able to find
+    // a suitable, store-friendly counterpart for WinRT.
+    //
+    // There may be some room for a workaround whereby OnPointerMoved's values
+    // are compared to the values from OnMouseMoved in order to detect
+    // when this bug is active.  A suitable transformation could then be made to
+    // OnMouseMoved's values.  For now, however, the system-reported values are sent
+    // to SDL with minimal transformation: from native screen coordinates (in DIPs)
+    // to SDL window coordinates.

+           don't all resize the window right away to enforce the new hints.
+
+           Some of them resize only after:
+            - A user-initiated move or resize
+            - A code-initiated move or resize
+            - Hiding & showing window (Unmap & map)
+
+           The following move & resize seems to help a lot of WMs that didn't
+           properly update after the hints were changed. We don't do a
+           hide/show, because there are supposedly subtle problems with doing so

+# yuv2rgb
+C library for fast image conversion between yuv420p and rgb24.
+
+This is a simple library for optimized image conversion between YUV420p and rgb24.
+It was done mainly as an exercise to learn to use sse intrinsics, so there may still be room for optimization.
+
+For each conversion, a standard c optimized function and two sse function (with aligned and unaligned memory) are implemented.
+The sse version requires only SSE2, which is available on any reasonably recent CPU.
+The library also supports the three different YUV (YCrCb to be correct) color spaces that exist (see comments in code), and others can be added simply.
+
+There is a simple test program, that convert a raw YUV file to rgb ppm format, and measure computation time.
+Optionally, it also compares the result and computation time with the ffmpeg implementation (that uses MMX), and with the IPP functions.
+
+To compile, simply do :
+
+    mkdir build
+    cd build
+    cmake -DCMAKE_BUILD_TYPE=Release ..
+    make
+
+The test program only support raw YUV files for the YUV420 format, and ppm for the RGB24 format.
+To generate a raw yuv file, you can use avconv:
+
+    avconv -i example.jpg -c:v rawvideo -pix_fmt yuv420p example.yuv
+
+To generate the rgb file, you can use the ImageMagick convert program:
+
+    convert example.jpg example.ppm
+
+Then, for YUV420 to RGB24 conversion, use the test program like that:
+
+    ./test_yuv_rgb yuv2rgb image.yuv 4096 2160 image
+  
+The second and third parameters are image width and height (that are needed because not available in the raw YUV file), and fourth parameter is the output filename template (several output files will be generated, named for example output_sse.ppm, output_av.ppm, etc.)
+
+Similarly, for RGB24 to YUV420 conversion:
+
+    ./test_yuv_rgb yuv2rgb image.ppm image
+
+On my computer, the test program on a 4K image give the following for yuv2rgb:
+
+    Time will be measured in each configuration for 100 iterations...
+    Processing time (std) : 2.630193 sec
+    Processing time (sse2_unaligned) : 0.704394 sec
+    Processing time (ffmpeg_unaligned) : 1.221432 sec
+    Processing time (ipp_unaligned) : 0.636274 sec
+    Processing time (sse2_aligned) : 0.606648 sec
+    Processing time (ffmpeg_aligned) : 1.227100 sec
+    Processing time (ipp_aligned) : 0.636951 sec
+
+And for rgb2yuv:
+
+    Time will be measured in each configuration for 100 iterations...
+    Processing time (std) : 2.588675 sec
+    Processing time (sse2_unaligned) : 0.676625 sec

+    Processing time (ffmpeg_aligned) : 3.397952 sec

+// Provide optimized functions to convert images from 8bits yuv420 to rgb24 format
+
+// There are a few slightly different variations of the YCbCr color space with different parameters that 
+// change the conversion matrix.
+// The three most common YCbCr color space, defined by BT.601, BT.709 and JPEG standard are implemented here.
+// See the respective standards for details
+// The matrix values used are derived from http://www.equasys.de/colorconversion.html
+
+// YUV420 is stored as three separate channels, with U and V (Cb and Cr) subsampled by a 2 factor
+// For conversion from yuv to rgb, no interpolation is done, and the same UV value are used for 4 rgb pixels. This 
+// is suboptimal for image quality, but by far the fastest method.
+
+// For all methods, width and height should be even, if not, the last row/column of the result image won't be affected.
+// For sse methods, if the width if not divisable by 32, the last (width%32) pixels of each line won't be affected.

+# The following will 1. create a build directory and 2. change into it and
+# call cmake to configure the build with default parameters as a static
+# library.
+#
+#   cmake -E make_directory build
+#   cmake -E chdir build cmake ..
+#
+# For a dynamic library, use
+#
+#   cmake -E chdir build cmake -D BUILD_SHARED_LIBS:BOOL=true ..
+#
+# For a framework on OS X, use
+#
+#   cmake -E chdir build cmake -G Xcode -D BUILD_FRAMEWORK:BOOL=true ..
+#
+# For an iOS static library, use
+#
+#   cmake -E chdir build cmake -G Xcode -D IOS_PLATFORM=OS ..
+#
+# or
+#
+#   cmake -E chdir build cmake -G Xcode -D IOS_PLATFORM=SIMULATOR ..
+#
+# Finally, build the project with:
+#
+#   cmake --build build
+#
+# Install it with
+#
+#   (sudo) cmake --build build --target install
+#
+# A binary distribution can be made with
+#
+#   cmake --build build --config Release --target package
+#
+# Please refer to the cmake manual for further options, in particular, how
+# to modify compilation and linking parameters.
+#
+# Some notes.
+#
+# . `cmake' creates configuration files in
+#
+#     <build-directory>/include/freetype/config
+#
+#   which should be further modified if necessary.
+#
+# . You can use `cmake' directly on a freshly cloned FreeType git
+#   repository.
+#
+# . `CMakeLists.txt' is provided as-is since it is normally not used by the
+#   developer team.
+#
+# . Set the `FT_WITH_ZLIB', `FT_WITH_BZIP2', `FT_WITH_PNG', and
+#   `FT_WITH_HARFBUZZ' CMake variables to `ON' to force using a dependency.
+#   Leave a variable undefined (which is the default) to use the dependency
+#   only if it is available.  Set `CMAKE_DISABLE_FIND_PACKAGE_HarfBuzz=TRUE' to
+#   disable a dependency completely (CMake package name, so `BZip2' instead of
+#   `BZIP2'). Example:
+#
+#     cmake -DFT_WITH_ZLIB=ON -DCMAKE_DISABLE_FIND_PACKAGE_HarfBuzz=TRUE [...]
+#
+# . Installation of FreeType can be controlled with the CMake variables
+#   `SKIP_INSTALL_HEADERS', `SKIP_INSTALL_LIBRARIES', and `SKIP_INSTALL_ALL'
+#   (this is compatible with the same CMake variables in zlib's CMake
+#   support).
+
+# FreeType explicitly marks the API to be exported and relies on the compiler
+# to hide all other symbols. CMake supports a C_VISBILITY_PRESET property
+# starting with 2.8.12.

+
+	* src/truetype/ttinterp.c (Ins_MIRP): Use ADD_LONG.
+
+2018-04-15  Alexei Podtelezhnikov  <apodtele@gmail.com>
+
+	[build] Use `info' function of make 3.81.
+
+	* configure, docs/INSTALL, docs/INSTALL.CROSS, docs/INSTALL.GNU,

+
+2018-04-10  Nikolaus Waxweiler  <madigens@gmail.com>
+
+	* CMakeLists.txt, builds/cmake/FindHarfBuzz.cmake: Extensive
+	modernization measures.
+
+	This brings up the minimum required CMake version to 2.8.12.
+
+	The installation paths follow the GNU defaults now, e.g. installing on a
+	64 bit host will place binaries into the lib64/ folder on e.g. Fedora.
+
+	Symbols are hidden by default (e.g. `-fvisibility=hidden' on GCC).
+
+	CMake will no longer look for a C++ compiler.
+
+	Library and .so version now match the Autotools build.
+
+	Comments in the build file and informational messages now use platform
+	agnostic example commands.
+
+	ftoption.h and ftconfig.h are written directly without a redundant `-new'
+	copy.
+
+	External dependencies are expressed as option()s and will turn up as such
+	in cmake-gui.
+
+	Internal: Properties such as dependencies and include directories are now
+	privately set on the freetype library instead of globally.
+
+	The CPack definitions have been cleaned up, the `make dist' has been
+	removed. Source packages generated with CPack don't contain Autotools
+	files and aren't used by the maintainters anyway.
+
+	On Windows, src/base/ftver.rc is compiled to decorate the library with
+	version and copyright information.
+
+	A pkg-config file is now generated and installed.

+	[truetype] Integer overflow issues.
+
+	Reported as

+	  https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=7453
+
+	* src/truetype/ttinterp.c (Round_Super, Round_Super_45): Use
+	ADD_LONG and SUB_LONG.
+
+2018-04-06  Alexei Podtelezhnikov  <apodtele@gmail.com>
+
+	[windows, wince] Clean up legacy project files.

+	* builds/wince/vc2005-ce/freetype.vcproj,

+	  https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=7371
+
+	* src/cff/cffload.c (cff_load_private_dict): Sanitize
+	`priv->blue_shift' and `priv->blue_fuzz' to avoid overflows later
+	on.
+
+	* src/type1/t1load.c (T1_Open_Face): Ditto.
+
+2018-04-04  Ben Wagner  <bungeman@google.com>
+
+	* src/truetype/ttobjs.c (trick_names): Add 3 tricky fonts (#53554),
+	`DFHei-Md-HK-BF', `DFKaiShu-Md-HK-BF' and `DFMing-Bd-HK-BF'.
+	(tt_check_trickyness_sfnt_ids): Add checksums for 3 tricky fonts
+	in above.
+
+2018-04-01  Werner Lemberg  <wl@gnu.org>
+
+	* builds/toplevel.mk (work): Use $(SEP).
+
+	This fixes the `make refdoc' using Cygwin: $(CAT) is `type' on this
+	platform, and this program only understands backslashes in paths.
+
+	Reported by Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com>.
+
+2018-03-30  Werner Lemberg  <wl@gnu.org>
+

+
+2018-03-09  Chun-wei Fan  <fanc999@yahoo.com.tw>
+
+	* CMakeLists.txt [win32]: Allow MSVC DLL builds (#53287).
+
+	Do not limit DLL builds to MinGW, since we already have
+	`__declspec(dllexport)' directives in `ftconfig.h'.
+	Also suppress more warnings for POSIX functions.
+
+2018-03-08  Hugh McMaster  <hugh.mcmaster@outlook.com>
+
+	Make installation of `freetype-config' optional (#53093).
+
+	* builds/unix/configure.raw: Add option `--enable-freetype-config'

+

+	* docs/INSTALL.ANY: Updated.
+
+2018-03-05  Werner Lemberg  <wl@gnu.org>

+	SUB_LONG; avoid FT_ABS.
+
+2018-02-04  Alexei Podtelezhnikov  <apodtele@gmail.com>
+
+	[unix] Use -fvisibility=hidden.
+
+	It is now widely recommended that ELF shared libraries hide symbols
+	except those with explicit __attribute__((visibility("default"))).
+	This is supported by all major compilers and should rather be an
+	option in libtool.

+	[psaux] Fix Type 1 glyphs with too many stem hints.
+
+	According to the CFF specification, charstrings can have up to 96 stem
+	hints. Due to hint replacement routines in Type 1 charstrings, some
+	glyphs are rejected by the Adobe engine, which implements the above
+	limit. This fix turns off hinting for such glyphs.

+2018-01-06  Werner Lemberg  <wl@gnu.org>
+
+	Add `FT_Done_MM_Var'.

+	[sfnt] Fix charmap type 2 iterator (#52646).
+
+	The subsetted demo font of the report that exhibits the bug has a

+	0xFA), and a second one for higher byte 0x01 (just for character

+	Use Adobe hinting engine for `light' hinting of both CFF and Type 1.
+
+	Since Ewald Hew factored the Adobe hinting engine out of the CFF

+	both have the same hinting philosophy.
+
+	This change activates the Adobe hinter when in LIGHT mode, and

+	[smooth] Fix complex rendering at high ppem.

+	[psaux] Extend Adobe interpreter (div, four-byte numbers).
+
+	* src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_escDIV>: Add
+	Type 1 mode.  Type 1 requires large integers to be followed by
+	`div'; cf. `Adobe Type 1 Font Format', section 6.2.
+	<op == 255>: Push Type 1 four-byte numbers as `Int' always.  This is
+	to ensure `div' and `callsubr' get values they can use.
+
+2017-09-25  Ewald Hew  <ewaldhew@gmail.com>
+
+	[psaux] Extend Adobe interpreter (hints).
+
+	* src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_cmdHSTEM,

+	Allow adding hints mid-charstring.
+	<cf2_escVSTEM3, cf2_escHSTEM3>: Translate into equivalent commands

+	stem positions.
+	Correction for left sidebearing.
+
+2017-09-25  Ewald Hew  <ewaldhew@gmail.com>
+
+	[psaux] Extend Adobe interpreter (hsbw, sbw).
+
+	* src/psaux/psintrp.c (cf2_doStems): `hsbw' or `sbw' must be the
+	first operation in a Type 1 charstring.
+	(cf2_interpT2CharString): Remove unused variables.
+	<cf2_cmdHMOVETO, cf2_cmdVMOVETO, cf2_cmdRMOVETO>: `hsbw' or `sbw'

+
+	[psaux] Extend Adobe interpreter (closepath).
+
+	* src/psaux/psintrp.c (cf2_interpT2CharString) <c2f_cmdCLOSEPATH>:
+	Use the right builder function.  We can use the `haveWidth' boolean
+	already present, instead of implementing `parse_state'.
+
+2017-09-25  Ewald Hew  <ewaldhew@gmail.com>
+
+	[psaux] Add Type 1 operations to Adobe CFF interpreter.
+
+	The following Type 1 specific ops have been added (copied from
+	`t1decode'):
+
+	  closepath
+	  vstem3
+	  hstem3
+	  seac
+	  sbw
+	  callothersubr
+	  pop
+	  setcurrentpoint
+	  hsbw
+
+	The following require a Type 1 mode, because of differences in
+	specification:
+
+	  hstem
+	  vstem
+	  vmoveto
+	  callsubr
+	  div
+	  rmoveto
+	  hmoveto
+	  Numbers
+
+	The subsequent commits will implement these changes and adapt

+
+	* src/psaux/psintrp.c: Add opcodes to enum.
+	(cf2_interpT2CharString): Copy relevant code over from

+
+2017-09-25  Ewald Hew  <ewaldhew@gmail.com>
+
+	[type1] Fixes for rendering.
+
+	The Type 1 advance width calculation passes null for glyph slot,

+
+	[psaux] Add missing objects (2/2).
+
+	Synthesize a `SubFont' object for Type 1 fonts.  This is used in the
+	interpreter to access Private dict data, which are stored in
+	different places for Type 1 and CFF.  This allows the same data to
+	be used in either mode.
+
+	* src/psaux/psobjs.c (t1_make_subfont): New procedure to copy
+	required values to a dummy `CFF_SubFont' object.  This is similar to

+	unavailable in Type 1 mode.
+
+	* include/freetype/internal/psaux.h (T1_Decoder, PS_Decoder): New

+
+2017-09-25  Ewald Hew  <ewaldhew@gmail.com>
+
+	[psaux, type1] Reorganize object fields.

+	way regardless of Type 1 or CFF.
+
+	* include/freetype/internal/psaux.h (PS_Builder): Change `TT_Face'
+	to `FT_Face'.
+	Remove unused fields.

+
+	[cff] Fix family name logic of pure CFF fontdata (#52056).
+
+	1. If `FamilyName' is present in the CFF font, use this for
+	   FT_Face's `family_name'.
+	2. Otherwise, use the face name and chop off any subset prefix.
+	3. If at this point FT_Face's `family_name' is set, use this
+	   together with the full name to determine the style.
+	4. Otherwise, use `CIDFontName' as FT_Face's `family_name'.
+	5. If we don't have a valid style, use "Regular".
+
+	Previously, FT_Face's `family_name' entry for pure CFF fontdata
+	nearly always was the fontname itself, instead of the `FamilyName'
+	entry in the CFF font (assuming there is one).
+
+	* src/cff/cffobjs.c (cff_face_init) [pure_cff]: Implement it.
+
+2017-09-18  Alexei Podtelezhnikov  <apodtele@gmail.com>
+
+	[build] Declutter Visual C++ 2010-2017 project.
+

+	the AVERAGE_WIDTH property.
+
+2002-02-06  David Turner  <david@freetype.org>
+
+	* src/sfnt/sfobjs.c (SFNT_Load_Face): Since many fonts embedded in
+	PDF documents do not include 'cmap', 'post' and 'name' tables, the
+	SFNT face loader has been changed to not immediately report an
+	error if these are not present.

+	Note that the specification _requires_ these tables, but Adobe
+	seems to ignore it completely.
+
+	* src/sfnt/ttcmap.c: Removing compiler warnings.

+	embedded bitmaps.
+
+2002-02-04  Keith Packard  <keithp@keithp.com>
+

+2002-02-02  Keith Packard  <keithp@keithp.com>
+
+	* builds/unix/freetype-config.in: Add missing `fi'.
+
+
+	* Version 2.0.7 released.
+	=========================
+
+
+2002-02-01  David Turner  <david@freetype.org>
+
+	* include/freetype/freetype.h: Increasing FREETYPE_PATCH to 7
+	for the new release.
+
+2002-01-31  David Turner  <david@freetype.org>
+
+	* README, README.UNX, docs/CHANGES: Updating documentation for the

+
+2002-01-30  David Turner  <david@freetype.org>

+	* INSTALL: Moved to ...
+	* docs/INSTALL: Here to avoid conflicts with the `install' script on
+	Windows, where the filesystem doesn't preserve case.
+
+2002-01-29  David Turner  <david@freetype.org>
+
+	* configure: Fixed the script.  It previously didn't accept more
+	than one argument correctly.  For example, when typing:
+
+	  ./configure --disable-shared --disable-nls
+
+	the `--disable-nls' was incorrectly sent to the `make' program.
+
+2002-01-29  Werner Lemberg  <wl@gnu.org>
+
+	* README.UNX: Fix typo.
+	* builds/unix/install.mk (uninstall): Fix library name for libtool.
+
+2002-01-28  Francesco Zappa Nardelli  <Francesco.Zappa.Nardelli@ens.fr>
+
+	* src/pcf/pcfdriver.c (PCF_Done_Face): Fix incorrect destruction of
+	the face object (face->toc.tables, face->root.family_name,
+	face->root.available_size, face->charset_encoding,
+	face->charset_registry are now freed).  Thanks to Niels Moseley.
+
+2002-01-28  Roberto Alameda  <ojancano@geekmail.de>
+
+	* src/type1/t1load.c (parse_encoding): Set `loader->num_chars'.
+
+2002-01-28  Werner Lemberg  <wl@gnu.org>
+
+	* src/type1/t1load.c (parse_subrs, parse_charstrings): Use copy
+	of `base' string for decrypting to not modify the original data.
+	Based on a patch by Jakub Bogusz <qboosh@pld.org.pl>.
+
+2002-01-27  Giuliano Pochini  <pochini@shiny.it>
+
+	* src/smooth/ftgrays.c (gray_render_scanline): Fix bug which caused
+	bad rendering of thin lines (less than one pixel thick).
+
+2002-01-25  Werner Lemberg  <wl@gnu.org>
+
+	* src/cff/cffdrivr.c (cff_get_name_index): Make last patch work
+	actually.

+
+2002-01-18  Detlef Würkner  <TetiSoft@apg.lahn.de>
+
+	* builds/amiga/src/base/ftsystem.c: Updated for AmigaOS 3.9.

+
+2002-01-18  Ian Brown  <ian.brown@printsoft.de>
+
+	* builds/win32/visualc/freetype.dsp: Updated.
+
+2002-01-13  Werner Lemberg  <wl@gnu.org>
+
+	* builds/unix/freetype2.a4: The script was still buggy.
+	* builds/unix/freetype-config.in: Make it really work for any install
+	prefix.
+
+2002-01-10  Werner Lemberg  <wl@gnu.org>
+
+	* builds/unix/freetype2.a4: Fix some serious bugs.
+
+2002-01-09  David Turner  <david@freetype.org>
+
+	* builds/unix/configure.ac: Build top-level Jamfile.
+
+2002-01-09  Maxim Shemanarev  <mcseemagg@yahoo.com>
+
+	* src/smooth/ftgrays.c (gray_render_line): Small optimization to
+	the smooth anti-aliased renderer that deals with vertical segments.
+	This results in a 5-7% speedup in rendering speed.
+
+2002-01-08  David Turner  <david@freetype.org>
+
+	Added some wrapper scripts to make the installation more
+	Unix-friendly.
+

+
+	* INSTALL, README.UNX: Updated installation documentation to use the
+	new 'configure' and 'install' scripts.
+
+2002-01-07  David Turner  <david@freetype.org>
+
+
+	* Version 2.0.6 released.
+	=========================
+
+
+	* docs/BUGS, docs/CHANGES: Updating documentation for 2.0.6 release.
+
+	* src/tools/docmaker.py: Fixed HTML quoting in sources.
+	(html_format): Replaced with ...
+	(html_quote): New function.
+	(html_quote0): New function.
+	(DocCode::dump_html): Small improvement.
+	(DocParagraph::dump, DocBlock::html): Use html_quote0 and html_quote.
+
+	* include/freetype/config/ftoption.h: Setting default options for
+	a release build (debugging off, bytecode interpreter off).
+
+	* src/base/ftobjs.c, src/base/ftoutln.c, src/cache/ftccmap.c,
+	src/cff/cffload.c, src/cff/cffobjs.c, src/pshinter/pshalgo2.c,
+	src/sfnt/ttload.c, src/sfnt/ttsbit.c: Removing small compiler
+	warnings (in pedantic compilation modes).
+
+2002-01-05  David Turner  <david@freetype.org>
+
+	* src/autohint/ahhint.c (ah_align_linked_edge): Modified computation
+	of auto-hinted stem widths; this avoids color fringes in
+	`ClearType-like' rendering.
+
+	* src/truetype/ttgload.c (TT_Load_Glyph_Header,
+	TT_Load_Simple_Glyph, TT_Load_Composite_Glyph, load_truetype_glyph):
+	Modified the TrueType loader to make it more paranoid; this avoids
+	nasty buffer overflows in the case of invalid glyph data (as
+	encountered in the output of some buggy font converters).
+
+2002-01-04  David Turner  <david@freetype.org>
+
+	* README.UNX: Added special README file for Unix users.
+
+	* builds/unix/ftsystem.c (FT_New_Stream): Fixed typo.
+
+	* src/base/ftobjs.c: Added #include FT_OUTLINE_H to get rid
+	of compiler warnings.
+
+	* src/base/ftoutln.c (FT_Outline_Check): Remove compiler warning.
+
+2002-01-03  Werner Lemberg  <wl@gnu.org>
+
+	* src/type1/t1objs.c (T1_Face_Init): Add cast to avoid compiler
+	warning.
+
+2002-01-03  Keith Packard  <keithp@keithp.com>
+
+	* builds/unix/ftsystem.c (FT_New_Stream): Added a fix to ensure that
+	all FreeType input streams are closed in child processes of a `fork'
+	on Unix systems.  This is important to avoid (potential) access
+	control issues.
+
+2002-01-03  David Turner  <david@freetype.org>
+
+	* src/type1/t1objs.c (T1_Face_Init): Fixed a bug that crashed the
+	library when dealing with certain weird fonts like `Stalingrad', in
+	`sadn.pfb' (this font has no full font name entry).
+
+	* src/base/ftoutln.c, include/freetype/ftoutln.h (FT_Outline_Check):
+	New function to check the consistency of outline data.
+
+	* src/base/ftobjs.c (FT_Load_Glyph): Use `FT_Outline_Check' to
+	ensure that loaded glyphs are valid.  This allows certain fonts like
+	`tt1095m_.ttf' to be loaded even though it appears they contain
+	really funky glyphs.
+
+	There still is a bug there, though.
+
+	* src/truetype/ttgload.c (load_truetype_glyph): Fix error condition.
+
+2001-12-30  David Turner  <david@freetype.org>
+
+	* src/autohint/ahhint.c (ah_hinter_load): Fix advance width
+	computation of auto-hinted glyphs.  This noticeably improves the
+	spacing of letters in KDE and Gnome.
+
+2001-12-25  Antoine Leca  <Antoine-Freetype@Leca-Marti.org>
+
+	* builds/dos/detect.mk: Correcting the order for Borland compilers:
+	16-bit bcc was never selected, always overridden by 32-bit bcc32.
+
+2001-12-22  Francesco Zappa Nardelli  <Francesco.Zappa.Nardelli@ens.fr>
+
+	* src/pcf/pcfread.c (pcf_load_font): Handle property `POINT_SIZE'
+	and fix incorrect computation of `available_sizes'.
+
+2001-12-22  David Turner  <david@freetype.org>
+
+	* src/autohint/ahhint.c (ah_hinter_load): Auto-hinted glyphs had an
+	incorrect glyph advance in the case of mono-width fonts (like
+	Courier, Andale Mono, and others).
+
+2001-12-22  Detlef Würkner  <TetiSoft@apg.lahn.de>
+
+	* builds/amiga/*: Adaptations to latest changes.
+	Support added for MorphOS.
+
+2001-12-22  Werner Lemberg  <wl@gnu.org>
+
+	* src/pshinter/pshrec.c (FT_COMPONENT): Redefine to `trace_pshrec'.
+	(ps_mask_table_merge, ps_hints_open, ps_hints_stem,
+	ps_hints_t1stem3, ps_hints_t2mask, ps_hints_t2counter): Fix
+	FT_ERROR messages.
+	* src/pshinter/pshalgo1.c (FT_COMPONENT): Define as
+	`trace_pshalgo1'.
+	* src/pshinter/pshalgo2.c (FT_COMPONENT): Define as
+	`trace_pshalgo2'.
+	* include/freetype/internal/ftdebug.h (FT_Trace): Updated.
+
+	* docs/modules.txt: New file.
+
+2001-12-21  David Turner  <david@freetype.org>
+
+	* src/pshinter/pshrec.c (ps_hints_t2mask, ps_hints_t2counter):
+	Ignore invalid `hintmask' and `cntrmask' operators (instead of
+	returning an error).  Glyph 2028 of the CFF font `MSung-Light-Acro'
+	couldn't be rendered otherwise (it seems its charstring is buggy,
+	though this requires more analysis).
+	(FT_COMPONENT): Define.
+
+	* src/cff/cffgload.c (CFF_Parse_CharStrings), src/psaux/t1decode.c
+	(T1_Decoder_Parse_Charstrings), src/pshinter/pshalgo2.c (*), Fixed a
+	bug where the X and Y axis where inverted in the postscript hinter.
+	This caused problem when displaying on non-square surfaces.
+
+	* src/pshinter/pshalgo2.c: s/vertical/dimension/.
+
+	* src/pshinter/pshglob.c (psh_globals_new): Replaced a floating
+	point constant with a fixed-float equivalent.  For some reasons not
+	all compilers are capable of directly computing a floating pointer
+	constant casted to FT_Fixed, and will link a math library instead.
+
+2001-12-20  Werner Lemberg  <wl@gnu.org>
+
+	* src/cache/ftccache.c (ftc_node_destroy, ftc_cache_lookup): Fix
+	tracing strings.
+	* src/cache/ftccmap.c (ftc_cmap_family_init): Ditto.
+	* src/cache/ftcmanag.c (ftc_family_table_alloc,
+	ftc_family_table_free, FTC_Manager_Check): Ditto.
+	* src/cache/ftcsbits.c (ftc_sbit_node_load): Ditto.
+
+	* src/base/ftobjs.c (FT_Done_Library): Remove compiler warning.
+
+2001-12-20  David Turner  <david@freetype.org>

+	* src/cff/cffgload.h: Updated.
+	* src/cff/cffobjs.c: Include FT_INTERNAL_POSTSCRIPT_HINTS_H.
+	(CFF_Size_Get_Globals_Funcs, CFF_Size_Done, CFF_Size_Init,
+	CFF_Size_Reset, CFF_GlyphSlot_Done, CFF_GlyphSlot_Init): New
+	functions.
+	(CFF_Init_Face): Renamed to ...
+	(CFF_Face_Init): This.
+	Add hinter support.
+	(CFF_Done_Face): Renamed to ...
+	(CFF_Face_Done): This.
+	(CFF_Init_Driver): Renamed to ...
+	(CFF_Driver_Init): This.
+	(CFF_Done_Driver): Renamed to ...
+	(CFF_Driver_Done): This.
+	* src/cff/cffobjs.h: Updated.
+	* src/cff/cffdrivr.c (cff_driver_class): Updated.
+
+	* include/freetype/internal/t1types.h (CID_FaceRec): New member
+	`pshinter'.
+	* src/cid/cidgload.c (CID_Load_Glyph): Add hinter support.
+	* src/cid/cidobjs.c: Include FT_INTERNAL_POSTSCRIPT_HINTS_H.
+	(CID_GlyphSlot_Done, CID_GlyphSlot_Init, CID_Size_Get_Globals_Funcs,
+	CID_Size_Done, CID_Size_Init, CID_Size_Reset): New functions.
+	(CID_Done_Face): Renamed to ...
+	(CID_Face_Done): This.
+	(CID_Init_Face): Renamed to ...
+	(CID_Face_Init): This.
+	Add hinting support.
+	(CID_Init_Driver): Renamed to ...
+	(CID_Driver_Init): This.
+	(CID_Done_Driver): Renamed to ...
+	(CID_Driver_Done): This.

+	* src/cidriver.c: Updated.
+
+	* src/pshinter/pshrec.c (t2_hint_stems): Fixed.
+
+	* src/base/ftobjs.c (FT_Done_Library): Fixed a stupid bug that
+	crashed the library on exit.
+
+	* src/type1/t1gload.c (T1_Load_Glyph): Enable font matrix
+	transformation of hinted glyphs.
+
+	* src/cid/cidload.c (cid_read_subrs): Fix error condition.
+
+	* src/cid/cidobjs.c (CID_Face_Done): Fixed a memory leak; the subrs
+	routines were never released when CID faces were destroyed.
+
+	* src/cff/cffload.h, src/cff/cffload.c, src/cff/cffgload.c: Updated
+	to move the definition of encoding tables back within `cffload.c'
+	instead of making them part of a shared header (causing problems in
+	`multi' builds).  This reverts change 2001-08-08.
+
+	* docs/CHANGES: Updated for 2.0.6 release.
+	* docs/TODO: Added `stem3 and counter hints support' to the TODO
+	list for the Postscript hinter.
+	* docs/BUGS: Closed the AUTOHINT-NO-SBITS bug.
+
+2001-12-19  David Turner  <david@freetype.org>
+
+	* include/freetype/cache/ftcache.h: Added comments to indicate that
+	some of the exported functions should only be used by applications
+	that need to implement custom cache types.
+
+	* src/truetype/ttgload.c (cur_to_org, org_to_cur): Fixed a nasty bug
+	that prevented composites from loading correctly, due to missing
+	parentheses around macro parameters.
+
+	* src/sfnt/sfobjs.c (SFNT_Load_Face): Make the `post' and `name'
+	tables optional to load PCL fonts properly.
+
+	* src/truetype/ttgload.c (TT_Load_Glyph), src/base/ftobjs.c
+	(FT_Load_Glyph), include/freetype/freetype.h (FT_LOAD_SBITS_ONLY):
+	`Fixed' the bug that prevented embedded bitmaps to be loaded when
+	the auto-hinter is used.  This actually is a hack but will be enough
+	until the internal re-design scheduled for FreeType 2.1.
+
+	* src/raster/ftrend1.c (ft_raster1_render): Fixed a nasty outline
+	shifting bug in the monochrome renderer.
+
+	* README: Updated version numbers to 2.0.6.

+2001-12-14  Werner Lemberg  <wl@gnu.org>
+
+	* builds/mac/README: Updated.
+
+2001-12-14  Scott Long  <scott@swiftview.com>
+
+	* src/truetype/ttgload.c (load_truetype_glyph): Fixing crash when
+	dealing with invalid fonts (i.e. glyph size < 10 bytes).
+
+2001-12-14  Sam Latinga  <slouken@devolution.com>
+
+	* builds/mac/freetype.make: A new Makefile to build with MPW on
+	MacOS classic.

+	(T1_Load_Glyph), src/cid/cidgload.c (CID_Load_Glyph),
+	src/cff/cffgload.c (CFF_Load_Glyph): Fixed a serious bug common to
+	all font drivers (the advance width was never hinted when it
+	should).
+
+	* include/freetype/freetype.h (FREETYPE_PATCH): New macro.
+	* src/base/ftdbgmem.c (debug_mem_dummy) [!FT_DEBUG_MEMORY]: Don't
+	use `extern' keyword.
+
+2001-12-12  David Turner  <david@freetype.org>
+
+	* src/pshinter/pshglob.c (psh_blues_scale_zones, psh_blues_snap_stem
+	psh_globals_new): Adding correct BlueScale/BlueShift support, plus
+	family blues processing.
+	* src/pshinter/pshglob.h (PSH_BluesRec): Updated.
+
+	Started adding support for the Postscript hinter in the CFF module.

+
+2001-12-11  Werner Lemberg  <wl@gnu.org>
+
+	* src/sfnt/ttload.c (TT_Load_Generic_Header): Typos.
+
+2001-12-11  David Turner  <david@freetype.org>
+
+	* builds/unix/freetype-config.in: Modified the script to prevent
+	passing `-L/usr/lib' to gcc.
+
+	* docs/FTL.TXT: Simple fix (change `LICENSE.TXT' to `FTL.TXT').
+
+	* builds/unix/freetype2.m4: New file for checking configure paths.
+	We need to install it in $(prefix)/share/aclocal/freetype2.m4 but I
+	didn't modify builds/unix/install.mk yet.
+
+	* INSTALL: Updated the instructions to build shared libraries with
+	Jam.  They were simply wrong.
+
+	* src/base/fttrigon.c (FT_Cos): Fixed a small bug that caused
+	slightly improper results for `FT_Cos' and `FT_Sin' (example:
+	FT_Sin(0) == -1!).
+
+2001-12-11  Detlef Würkner  <TetiSoft@apg.lahn.de>
+
+	* include/freetype/internal/ftstream.h (GET_LongLE, GET_ULongLE):
+	Fixed incorrect argument types.
+
+2001-12-10  Francesco Zappa Nardelli  <Francesco.Zappa.Nardelli@ens.fr>
+
+	* src/pcf/pcfdriver.c (PCF_Init_Face): Allow Xft to use PCF fonts
+	by setting the `face->metrics.max_advance' correctly.

+
+2001-12-06  Leonard Rosenthol  <leonardr@lazerware.com>
+
+	Added support for reading .dfont files on Mac OS X.  Also added a
+	new routine which looks up a given font by name in the Mac OS and
+	returns the disk file where it resides.
+
+	* src/base/ftmac.c: Include <Files.h> and <TextUtils.h>.
+	(is_dfont): New auxiliary function.
+	(FT_New_Face_From_dfont): New function.
+	(FT_GetFile_From_Mac_Name): New exported function.

+
+2001-12-06  David Turner  <david@freetype.org>
+
+	* src/cache/Jamfile, src/cache/rules.mk: Updated.
+
+2001-12-06  Werner Lemberg  <wl@gnu.org>
+
+	* INSTALL: Small update.
+
+2001-12-05  David Turner  <david@freetype.org>
+
+	* src/base/ftglyph.c (FT_Glyph_To_Bitmap): Re-ordered code for
+	debugging purposes.
+	Comment out use of `origin'.
+
+	* src/smooth/ftsmooth.c (ft_smooth_render): Fixed a nasty hidden bug
+	where outline shifting wasn't correctly undone after bitmap
+	rasterization.  This created problems with certain glyphs (like '"'
+	of certain fonts) and the cache system.
+
+	* src/pshinter/pshalgo1.c (psh1_hint_table_init): Fix typo.
+	* src/pshinter/pshalgo2.c (psh2_hint_table_init): Fix typo.
+	(ps2_hints_apply): Small fix.
+
+2001-12-05  David Turner  <david@freetype.org>
+
+	* src/pshinter/pshalgo2.c (psh2_hint_table_init),
+	src/pshinter/pshalgo1.c (psh1_hint_table_init): Removed compiler
+	warnings.
+
+	* include/freetype/ftcache.h, include/freetype/cache/*, src/cache/*:
+	Yet another massive rewrite of the caching sub-system in order to
+	both increase performance and allow simpler cache sub-classing.  As
+	an example, the code for the image and sbit caches is now much
+	simpler.
+
+	I still need to update the documentation in
+	www/freetype2/docs/cache.html to reflect the new design though.
+
+	* include/freetype/config/ftheader.h (FT_CACHE_CHARMAP_H): New
+	macro.
+	(FT_CACHE_INTERNAL_CACHE_H): Updated.
+
+2001-12-05  David Krause  <freetype@davidkrause.com>
+
+	* docs/license.txt: s/X Windows/X Window System/.
+
+2001-12-04  Werner Lemberg  <wl@gnu.org>
+
+	* src/raster/ftraster.c: Fix definition condition of MEM_Set().
+	* src/smooth/ftgrays.c (M_Y): Change value to 192.
+	* src/base/ftdbgmem.c (ft_mem_table_destroy): Fix printf() parameter.
+	Remove unused variable.
+	* src/cache/ftcimage.c (ftc_image_node_init,
+	ftc_image_node_compare): Remove unused variables.
+	* src/cache/ftcsbits.c (ftc_sbit_node_weight): Remove unused
+	variable.
+	* src/raster/ftraster.c (MEM_Set): Move definition down to avoid
+	compiler warning.
+	* src/autohint/ahhint.c (ah_hinter_hint_edges): Use UNUSED() to
+	avoid compiler warnings.
+	* src/pcf/pcfread.c (tableNames): Use `const'.

+	* src/pshinter/pshrec.c (ps_hints_close): Remove redundant
+	declaration.
+	* src/pshinter/pshalgo1.c (psh1_hint_table_init): Rename variables
+	to avoid shadowing.
+	* src/pshinter/pshalgo2.c (psh2_hint_table_activate_mask): Ditto.
+	* src/type1/t1objs.h: Remove double declarations of `T1_Size_Init()'
+	and `T1_Size_Done()'.
+
+2001-11-20  Antoine Leca  <antoineleca@multimania.com>
+
+	* include/freetype/ttnameid.h: Added some new Microsoft language
+	codes and LCIDs as found in MSDN (Passport SDK).  Also added
+	comments about the meaning of bit 57 of the `OS/2' table
+	(TT_UCR_SURROGATES) which (with OpenType v.1.3) now means `there is
+	a character beyond 0xFFFF in this font'.  Thanks to Detlef Würkner
+	<TetiSoft@apg.lahn.de> for noticing this.
+
+2001-11-20  David Turner  <david@freetype.org>
+
+	* src/pshinter/{pshalgo2.c, pshalgo1.c}: Fixed stupid bug in sorting
+	routine that created nasty alignment artefacts.
+
+	* src/pshinter/pshrec.c, tests/gview.c: Debugging updates.
+
+	* src/smooth/ftgrays.c: De-activated experimental gamma support.
+	Apparently, `optimal' gamma tables depend on the monitor type,
+	resolution and general karma, so it's better to compute them outside
+	of the rasterizer itself.
+	(gray_convert_glyph): Use `volatile' keyword.
+
+2001-10-29  David Turner  <david@freetype.org>
+
+	Adding experimental `gamma' support.  This produces smoother glyphs
+	at small sizes for very little cost.
+
+	* src/smooth/ftgrays.c (grays_init_gamma): New function.
+	(gray_raster_new): Use it.
+
+	Various fixes to the auto-hinter.  They merely improve the output of
+	sans-serif fonts.  Note that there are still problems with serifed
+	fonts and composites (accented characters).
+
+	* src/autohint/ahglyph.c (ah_outline_load,
+	ah_outline_link_segments): Implement it.
+	Fix typos.
+	(ah_outline_save, ah_outline_compute_segments): Fix typos.
+	* src/autohint/ahhint.c (ah_align_serif_edge): New argument
+	`vertical'.  Implement improvement.
+	(ah_hint_edges_3, ah_hinter_hint_edges): Implement it.
+	Fix typos.
+	(ah_hinter_align_strong_points, ah_hinter_align_weak_points): Fix
+	typos.
+	(ah_hinter_load): Set `ah_debug_hinter' if DEBUG_HINTER is defined.
+	* src/autohint/ahmodule.c: Implement support for DEBUG_HINTER macro.
+	* src/autohint/ahtypes.h: Ditto.
+	(AH_Hinter): Remove `disable_horz_edges' and `disable_vert_edges'
+	(making them global as `ah_debug_disable_horz' and
+	`ah_debug_disable_vert').
+	Fix typos.
+
+	* tests/gview.c: Updated the debugging glyph viewer to show the
+	hints generated by the `autohint' module.
+
+2001-10-27  David Turner  <david@freetype.org>
+
+	* src/cache/ftcchunk.c (ftc_chunk_cache_lookup): Fixed a bug that
+	considerably lowered the performance of the abstract chunk cache.
+
+2001-10-26  David Turner  <david@freetype.org>
+
+	* include/freetype/ftcache.h, include/freetype/cache/*.h,
+	src/cache/*.c: Major re-design of the cache sub-system to provide
+	better performance as well as an `Acquire'/`Release' API.  Seems to
+	work well here, but probably needs a bit more testing.
+
+2001-10-26  Leonard Rosenthol  <leonardr@lazerware.com>
+
+	* builds/mac/README: Updated to reflect my taking over the project
+	and that is now being actively maintained.
+
+	* src/base/ftmac.c (parse_fond): Applied patches from Paul Miller
+	<paulm@profoundeffects.com> to support loading a face other than the
+	first from a FOND resource.
+	(FT_New_Face_From_FOND): Updated.
+
+2001-10-25  Leonard Rosenthol  <leonardr@lazerware.com>
+
+	* builds/mac/ftlib.prj: Update of CodeWarrior project file for Mac
+	OS for latest version (7) of CWPro and for recent changes to the FT
+	source tree.
+
+2001-10-25  David Turner  <david@freetype.org>
+
+	* include/freetype/config/ftoption.h: Updated comments to explain
+	precisely how to use project-specific macro definitions without
+	modifying this file manually.
+
+	(FT_CONFIG_FORCE_INT64): Define.
+
+	(FT_DEBUG_MEMORY): New macro.
+
+2001-10-24  Tom Kacvinsky  <tkacvins@freetype.org>
+
+	* builds/unix/ftsystem.c (FT_New_Memory): Added a missing `{'.
+
+2001-10-23  David Turner  <david@freetype.org>
+
+	* include/freetype/internal/ftmemory.h, src/base/ftdbgmem.c:
+	Improvements to the memory debugger to report more information in
+	case of errors.  Also, some allocations that occurred through REALLOC
+	couldn't be previously caught correctly.
+
+	* src/autohint/ahglyph.c (ah_outline_compute_segments,
+	ah_outline_compute_edges), src/raster/ftraster.c (ft_black_new),
+	src/smooth/ftgrays.c (gray_render_span, gray_raster_new): Replaced
+	liberal uses of memset() by the MEM_Set() macro.
+
+2001-10-23  David Turner  <david@freetype.org>
+
+	* src/raster/ftraster.c (Update): Removed to be inlined in ...
+	(Sort): Updated.
+
+2001-10-22  David Turner  <david@freetype.org>
+
+	* builds/unix/ftsystem.c (FT_New_Memory, FT_Done_Memory),
+	builds/vms/ftsystem.c (FT_New_Memory, FT_Done_Memory),
+	builds/amiga/ftsystem.c (FT_New_Memory, FT_Done_Memory),
+	src/base/ftdbgmem.c: Updated the memory debugger and
+	platform-specific implementations of `ftsystem' in order to be able
+	to debug memory allocations on Unix, VMS and Amiga too!
+
+	* src/pshinter/pshalgo2.c (psh2_hint_table_record_mask): Removed
+	some bogus warnings.
+
+	* include/freetype/internal/ftmemory.h, src/base/ftdbgmem.c:
+	Modified the debugging memory manager to report the location (source
+	file name + line number) where leaked memory blocks are allocated in
+	the source file.
+
+	* src/base/ftdbgmem.c: New debugging memory manager.  You must
+	define the FT_DEBUG_MEMORY macro in `ftoption.h' to enable it.  It
+	will record every memory block allocated and report simple errors
+	like memory leaks and double deletes.
+
+	* src/base/Jamfile: Include ftdbgmem.
+	* src/base/rules.mk: Ditto.
+	* src/base/ftbase.c: Include ftdbgmem.c.
+
+	* include/freetype/config/ftoption.h: Added the FT_DEBUG_MEMORY
+	macro definition.
+
+	* src/base/ftsystem.c (FT_New_Memory, FT_Done_Memory): Modified the
+	base component to use the debugging memory manager when the macro
+	FT_DEBUG_MEMORY is defined.
+
+2001-10-21  Tom Kacvinsky  <tkacvins@freetype.org>
+
+	* src/cff/cffload.c (CFF_Done_Font): Free subfonts array only if
+	we are working with a CID keyed CFF font.  Otherwise, a variable
+	that was never allocated memory might freed.  This is a correction
+	to the previous patch for freeing subfonts.
+
+2001-10-21  Tom Kacvinsky  <tkacvins@freetype.org>
+
+	* src/cff/cffload.c (CFF_Done_Font): Free the subfonts array to
+	avoid a memory leak.
+
+2001-10-21  David Turner  <david@freetype.org>
+
+	* src/pshinter/pshalgo2.c, src/pshinter/pshalgo1.c,
+	src/pshinter/pshglob.c: Removing compiler warnings in pedantic modes
+	(in multi-object compilation mode, mainly).
+
+2001-10-20  Tom Kacvinsky  <tkacvins@freetype.org>
+
+	* src/type1/t1load.c (parse_encoding): Add a test to make sure
+	that custom encodings (i.e., neither StandardEncoding nor
+	ExpertEncoding) are not loaded twice when the Type 1 font is
+	synthetic.
+
+	* src/type1/t1load.c (parse_font_name, parse_subrs): Added a test
+	for when loading synthetic fonts to make sure that the font name
+	and subroutines are not loaded twice.  This is to remove a memory
+	leak that occurred because the original memory blocks for these
+	objects were not deallocated when the objects were parsed the
+	second time.
+
+2001-10-19  David Turner  <david@freetype.org>
+
+	* src/smooth/ftgrays.c, src/pshinter/pshglob.h,
+	src/pshinter/pshrec.c, src/pshinter/pshalgo2.c: Getting rid of
+	compiler warnings.
+
+	* src/pshinter/module.mk, src/pshinter/rules.mk: Adding control
+	files to build the PostScript hinter with the `old' build system.

+
+	* descrip.mms, src/pshinter/descrip.mms: Updates to the VMS build
+	files.
+
+2001-10-18  David Turner  <david@freetype.org>
+
+	* src/psnames/pstables.h, src/tools/glnames.py: Rewrote the
+	`glnames.py' script used to generate the `pstables.h' header file.
+	The old one contained a serious bug that made FreeType return
+	incorrect glyph names for certain glyphs.
+
+	* src/truetype/ttdriver.c (Set_Char_Sizes): Changing computation of
+	pixel size from character size to use rounding.  This is an
+	experiment to see whether this gives values similar to Windows for
+	scaled ascent/descent/etc.
+
+	* src/base/ftcalc.c (FT_Div64by32): Changed the implementation
+	slightly since the original code was mis-compiled on Mac machines
+	using the MPW C compiler.
+
+	* src/base/ftobjs.c (FT_Realloc): When a memory block was grown
+	through FT_Realloc(), the new bytes were not set to 0, which created
+	some strange bugs in the PostScript hinter.
+	(destroy_face): Don't deallocate unconditionally.
+
+	* src/cid/cidgload.c (CID_Compute_Max_Advance, CID_Load_Glyph):
+	Adding support to new PostScript hinter.
+
+	* include/freetype/internal/psglobal.h,
+	include/freetype/internal/pshints.h,
+	include/freetype/config/ftmodule.h, src/pshinter/Jamfile,

+	src/pshinter/pshmod.c, src/pshinter/pshmod.h, src/pshinter/pshrec.c,
+	src/pshinter/pshrec.h: Adding new PostScript hinter module.
+
+	* include/freetype/internal/ftobjs.h,
+	include/freetype/internal/internal.h,
+	include/freetype/internal/psaux.h,
+	include/freetype/internal/t1types.h, src/psaux/psobjs.c,

+	src/type1/t1driver.c, src/type1/t1gload.c, src/type1/t1objs.c,
+	src/type1/t1objs.h: Updates to use the new PostScript hinter.
+
+	* tests/Jamfile, tests/gview.c: Adding a new glyph hinting
+	viewer/debugger to the source tree.  Note that you will _not_ be
+	able to compile it since it depends on an unavailable graphics
+	library named `Nirvana' to render vector images.
+
+2001-10-17  David Turner  <david@freetype.org>
+
+
+	* Version 2.0.5 released.
+	=========================
+
+
+	* include/freetype/freetype.h, include/internal/ftobjs.h,
+	src/base/ftobjs.c, src/type1/t1driver.c: Adding a new function named
+	'FT_Get_Postscript_Name' to retrieve the PostScript name of a given
+	font.  Should work with all formats except pure CFF/CEF fonts (this
+	will be added soon).
+
+	* src/cid/cidriver (cid_get_postscript_name): New function.
+	(CID_Get_Interface): Handle `postscript_name' interface.
+
+	* src/sfnt/sfdriver.c (get_sfnt_postscript_name): New function.

+
+2001-10-08  David Turner  <david@freetype.org>
+
+	Fixed a bug in `glnames.py' that prevented it from generating
+	correct glyph names tables.  This resulted in the unavailability of
+	certain glyphs like `Cacute', `cacute' and `lslash' in Unicode
+	charmaps, even if these were present in the font (causing problems
+	for Polish users).
+
+	* src/tools/glnames.py (mac_standard_names): Fixed.
+	(t1_standard_strings): Some fixes and renamed to ...
+	(sid_standard_names): This.
+	(t1_expert_encoding): Fixed.

+	* src/psnames/psmodule.c (PS_Unicode_Value): Fix offset.
+	Fix return value.
+	Use `sid_standard_table' and `ps_names_to_unicode' instead of
+	`t1_standard_glyphs' and `names_to_unicode'.
+	(PS_Macintosh_Name): Use `ps_glyph_names' instead of
+	`standard_glyph_names'.
+	(PS_Standard_Strings): Use `sid_standard_names' instead of
+	`t1_standard_glyphs'.
+

+
+2000-12-14  David Turner  <david.turner@freetype.org>

+	definition of the FT_BBox structure from the former to the latter.
+	* include/freetype/ftimage.h: Add `ft_raster_flag_clip' value to

+
+2000-12-13  David Turner  <david.turner@freetype.org>
+
+	* include/freetype/config/ft2build.h,
+	include/freetype/internal/internal.h: Fixed header inclusion macros
+	to use direct definitions.  This is the only way to do these things
+	in a portable way :-(  The rest of the code should follow shortly
+	though everything compiles now.
+
+	* builds/compiler/intelc.mk, builds/compiler/watcom.mk: New files.
+
+	* builds/win32/detect.mk: Added support for the Intel C/C++

+	conditionals are off.
+
+2000-12-13  Werner Lemberg  <wl@gnu.org>

+2000-12-12  Werner Lemberg  <wl@gnu.org>
+
+	* include/freetype/config/ft2build.h (FT2_ROOT, FT2_CONFIG_ROOT):
+	Removed.  ANSI C doesn't (explicitly) allow macro expansion in
+	arguments using `##'.
+	(FT2_PUBLIC_FILE, FT2_CONFIG_FILE, FT2_INTERNAL_FILE): Use directory
+	names directly.  Make them configurable.  Use `##' to strip leading
+	and trailing spaces from arguments.
+
+	* builds/unix/ft2unix.h: Adapted.
+
+	* src/base/ftsystem.c (ft_alloc, ft_realloc, ft_free, ft_io_stream,

+
+2000-12-08  Werner Lemberg  <wl@gnu.org>

+	* src/truetype/ttinterp.c: Remove unused CALC_Length() macro.
+
+2000-12-07  David Turner  <david.turner@freetype.org>
+

+	* src/cff/cff.c, src/cff/rules.mk: Updated.
+
+2000-12-06  David Turner  <david.turner@freetype.org>
+
+	* src/cache/ftlru.c (FT_Lru_Done): Fixed memory leak.
+
+2000-12-06  Werner Lemberg  <wl@gnu.org>

+
+2000-12-05  David Turner  <david.turner@freetype.org>
+

+	header files (an FT_FLAT_COMPILE test was missing).
+
+	* src/cache/ftcmanag.c (FTC_Manager_Done): Fixed a bug that caused
+	an occasional crash when the function was called (due to a dangling
+	pointer).
+
+	* src/base/ftsystem.c (FT_Done_Memory): Fixed an obvious bug:
+	The ANSI `free()' function was called instead of `memory->free()'.
+
+	* docs/docmaker.py: Added section filtering, multi-page generation
+	(index page generation is still missing though).
+
+2000-12-04  David Turner  <david.turner@freetype.org>
+
+	* builds/unix/install.mk, builds/unix/ft2unix.h: The file `ft2unix.h'
+	is now installed as <ft2build.h> for Unix systems.  Note that we
+	still use the `freetype2/freetype' installation path for now.
+
+	* */*.[ch]: Now using <ft2build.h> as the default build and setup
+	configuration file in all public headers.  Internal source files
+	still need some changes though.
+
+	* builds/devel/ft2build.h, builds/devel/ftoption.h: Created a new
+	directory to hold all development options for both the Unix and
+	Win32 developer builds.
+
+	* builds/win32/detect.mk, builds/win32/w32-bccd.mk,
+	builds/win32/w32-dev.mk: Changed the developer build targets to
+	`devel-gcc' and `devel-bcc' in order to be able to develop with the
+	Borland C++ compiler.

+	files.
+
+2000-12-01  Werner Lemberg  <wl@gnu.org>
+
+	* INSTALL: Revised.
+	* builds/compiler/bcc-dev.mk, builds/compiler/visualage.mk,

+	`setup'.
+
+2000-11-30  David Turner  <david.turner@freetype.org>
+
+	* INSTALL: Slightly updated the quick starter documentation to
+	include IDE compilation, prevent against BSD Make, and specify `make
+	setup' instead of a single `make' for build configuration.
+
+	* include/config/ftbuild.h, include/internal/internal.h: Added new
+	configuration files used to determine the location of all public,
+	configuration, and internal header files for FreeType 2.  Modified

+	src/truetype/ttobjs.c, src/truetype/ttgload.c,
+	src/truetype/ttinterp.c: Fixed a few comparisons that Borland C++
+	didn't really like.  Basically, this compiler complains when FT_UInt
+	is compared to FT_UShort (apparently, it promotes `UShort' to `Int'
+	in these cases).
+
+2000-11-30  Tom Kacvinsky  <tkacvins@freetype.org>
+
+	* t2objs.c (T2_Init_Face): Added calculation of `face->height' for

+	parentheses.
+
+2000-11-26  Tom Kacvinsky  <tkacvins@freetype.org>
+
+	* src/cff/t2gload.c (T2_Parse_CharStrings): Added logic to glyph

+	and glyph width operand before endchar/hmoveto/vmoveto.
+
+2000-11-26  Werner Lemberg  <wl@gnu.org>
+
+	* builds/ansi/ansi.mk: Fix inclusion order of files.

+	* src/type1/t1parse.h: Adapted.
+

+
+	* src/cff/t2objs.c (T2_Init_Face): For pure CFF fonts, set

+	to 1000.
+
+	* src/cff/t2parse.c (parse_t2_real): Fixed real number parsing
+	loop.
+
+	* src/cff/t2load.c (T2_Get_String): Called T2_Get_Name with a

+
+	Say you have `(Foo*)x' and want to assign, pass, or return it as
+	`(Bar*)'.  If you simply say `x' or `(Bar*)x', then the C compiler
+	would warn you that type casting incompatible pointer types breaks
+	strict-aliasing.  The solution is to cast to `(void*)' instead which
+	is the generic pointer type, so the compiler knows that it should
+	make no strict-aliasing assumption on `x'.  But the problem with
+	`(void*)x' is that seems like in C++, unlike C, `void*' is not a
+	generic pointer type and assigning `void*' to `Bar*' without a cast
+	causes an error.  The solution is to cast to `Bar*' too, with
+	`(Bar*)(void*)x' as the result -- this is what the patch does.
+
+	* include/freetype/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP),
+	include/freetype/cache/ftcmru.h (FTC_MRULIST_LOOKUP_CMP): Remove
+	cast on lvalue, use a temporary pointer instead.
+	Cast temporarily to (void*) to not break strict aliasing.
+
+	* include/freetype/internal/ftmemory.h (FT_MEM_ALLOC,
+	FT_MEM_REALLOC, FT_MEM_QALLOC, FT_MEM_QREALLOC, FT_MEM_FREE),
+	src/base/ftglyph.c (FT_Glyph_To_Bitmap): Cast temporarily to (void*)
+	to not break strict aliasing.
+
+	* src/base/ftinit.c (FT_USE_MODULE): Fix wrong type information.
+
+	* builds/unix/configure.ac (XX_CFLAGS): Remove -fno-strict-aliasing.
+
+2005-05-23  David Turner  <dturner@freetype.org>
+
+	Fix Savannah bug #12213 (incorrect behaviour of the cache sub-system

+
+2005-02-25  David Turner  <david@freetype.org>
+
+	Implement several memory optimizations to drastically reduce the
+	heap usage of FreeType, especially in the case of memory-mapped
+	files.  The idea is to avoid loading and decoding tables in the
+	heap, and instead access the raw data whenever possible (i.e., when
+	it doesn't compromise performance).
+
+	This has several benefits: For example, opening vera.ttf now uses
+	just a small amount of memory (even when the FT_Library footprint is
+	accounted for), until you start loading glyphs.  Even then, you save
+	at least 20KB compared to the non-optimized case.  Performance of
+	various operations, including open and close, has also been
+	dramatically improved.
+
+	More optimizations to come, especially for the auto-hinter.

+
+2004-07-24  Derek B. Noonburg  <derekn@foolabs.com>
+
+	* src/cff/cffload.c (cff_font_load): Always create inverse mapping.

+
+	Fixed a dangling pointer bug in the cache code that happened in very

+	Fix bugs that prevented the stroker to correctly generate stroked
+	paths from closed paths, i.e., nearly all glyphs in vectorial fonts.
+
+	The code is still _very_ buggy though; treat with special care.
+
+	* src/base/ftstroke.c (FT_STROKE_TAG_BEGIN_END): New macro.
+	(ft_stroke_border_reverse): New function.
+	(ft_stroker_inside): Remove local variable `sigma'; use different

+	(FT_Stroker_EndSubPath): Call ft_stroker_inside and
+	ft_stroke_border_reverse.

+
+2004-06-24  David Turner  <david@freetype.org>
+
+
+	* Version 2.1.9 released.
+	=========================
+
+
+	* src/truetype/ttgload.c, src/truetype/ttxgvar.c: Removing
+	compiler warnings.
+
+2004-06-23  Werner Lemberg  <wl@gnu.org>
+
+	* include/freetype/internal/ftmemory.h [FT_DEBUG_MEMORY]: Declare

+2004-06-23  David Turner  <david@freetype.org>
+
+	* include/freetype/internal/ftmemory.h, src/base/ftutil.c
+	(FT_QAlloc, FT_QRealloc), src/base/ftdbgmem.c (FT_QAlloc_Debug,
+	FT_QRealloc_Debug): New functions that perform allocation without
+	zero-ing out the corresponding blocks.
+
+	* include/freetype/internal/ftmemory.h (FT_MEM_QALLOC,
+	FT_MEM_QREALLOC, FT_MEM_QNEW, FT_MEM_QNEW_ARRAY,

+	Small optimization in the kerning table verifier; this speeds up
+	TrueType face opening by about 7%.

+
+	* include/freetype/config/ftmodule.h: Changed the order of modules,
+	putting TrueType and Type 1 first.  This dramatically improves the
+	performance of face open/close operations.  For example, putting the
+	TrueType driver first in the list results in a 5x speedup when
+	opening `Vera.ttf'.
+
+	The very problem is that both the PCF and BDF drivers do a lot more
+	than necessary to detect that they cannot handle a font file.
+
+2004-06-22  Werner Lemberg  <wl@gnu.org>

+	interpreter was enabled.
+
+2004-06-14  Huw D M Davies  <h.davies1@physics.ox.ac.uk>
+

+
+2004-06-08  David Turner  <david@freetype.org>
+

+	* src/autofit/*: Important fixes to the auto-fitter.  The output
+	now seems to be 100% equivalent to the auto-hinter, while being
+	about 2% faster (which proves that script-specific algorithm
+	selection isn't a performance problem).
+
+	To test it, change `autohint' to `autofit' in
+	<freetype/config/ftmodule.h> and recompile.
+
+	A few more testing is needed before making this the official
+	auto-hinting module.

+	this data.  It no longer fails on parsing e.g.

+
+2004-02-03  Werner Lemberg  <wl@gnu.org>
+
+	* include/freetype/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP):
+	Initialize `node'.
+	* src/type1/t1load.c (parse_dict): Initialize `have_integer'.
+
+2004-02-02  Werner Lemberg  <wl@gnu.org>
+
+	* src/type1/t1load.c (parse_dict): Handle `RD' and `-|' commands
+	outside of /Subrs or /CharStrings.  This can happen if there is
+	additional code manipulating those two arrays so that FreeType
+	doesn't recognize them properly.
+	(T1_Open_Face): Improve an error message.
+
+2004-02-01  Werner Lemberg  <wl@gnu.org>
+
+	* src/type1/t1load.c (parse_charstrings): Exit immediately if
+	there are no elements in /CharStrings.  This is needed for fonts
+	like Optima-Oblique which not only define /CharStrings but access it
+	also.
+
+2004-02-01  David Turner  <david@freetype.org>
+
+	* src/sfnt/Jamfile: Removing `ttcmap' from the list of sources.
+
+	* include/freetype/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP)
+	<FTC_INLINE>: Provide macro version which doesn't use inline code.
+	* include/freetype/cache/ftcglyph.h (FTC_GCACHE_LOOKUP_CMP)
+	<FTC_INLINE>: Ditto.
+	Use FTC_MRULIST_LOOKUP_CMP.
+	* include/freetype/cache/ftcmru.h (FTC_MRULIST_LOOKUP_CMP): New
+	macro.
+	(FTC_MRULIST_LOOKUP): Use it.
+
+	* src/cache/Jamfile (_sources), src/cache/descrip.mms: Updated.
+	* src/cache/ftcbasic.c: Fix compiler warnings.
+	* src/cache/ftcmanag.c (FTC_Manager_LookupSize,
+	FTC_Manager_LookupFace) <FTC_INLINE>: Use FTC_MRULIST_LOOKUP_CMP.
+	* src/cache/ftcmru.c (FTC_MruList_Find): Fix a bug (found after
+	heavy testing).
+
+	* Jamfile: Updating `refdoc' target, and adding `autohint' to the
+	list of modules to build.  Both the autohinter and autofitter will
+	be built by default.  But which one will be used is determined by
+	the content of `ftmodule.h'.
+
+	* src/autofit/*: Many updates, but the code is still buggy...
+
+2004-01-31  Werner Lemberg  <wl@gnu.org>
+
+	* src/cff/cffgload.c (cff_operator_seac): Fix magnitude of

+
+2004-01-30  Werner Lemberg  <wl@gnu.org>
+
+	* src/type1/t1parse.c (T1_Get_Private_Dict): Use FT_MEM_MOVE, not
+	FT_MEM_COPY, for copying the private dict.
+
+	* src/type1/t1load.c (parse_subrs): Assign number of subrs only
+	in first run.
+	(parse_charstrings): Parse /CharStrings in second run without
+	assigning values.
+	(parse_dict): Skip all /CharStrings arrays but the first.  We need
+	this for non-standard fonts like `Optima' which have different
+	outlines depending on the resolution.  Note that there is no
+	guarantee that we get fitting /Subrs and /CharStrings arrays; this
+	can only be done by a real PS interpreter.
+
+2004-01-29  Antoine Leca  <Antoine-Freetype@Leca-Marti.org>

+	* src/cid/cidload.h: Updated.
+
+	* src/cid/cidobjs.c (cid_face_done): Free `binary_data' and

+
+	  *Complete* rewrite of the cache sub-system to `solve' the
+	  following points:
+
+	    - all public APIs have been moved to FT_CACHE_H, everything
+	      under `include/freetype/cache' is only needed by client
+	      applications that want to implement their own caches
+
+	    - a new function named FTC_Manager_RemoveFaceID to deal
+	      with the uninstallation of FaceIDs
+
+	    - the image and sbit cache are now abstract classes, that
+	      can be extended much more easily by client applications
+
+	    - better performance in certain areas.  Further optimizations
+	      to come shortly anyway...
+
+	    - the FTC_CMapCache_Lookup function has changed its signature,
+	      charmaps can now only be retrieved by index
+
+	    - FTC_Manager_Lookup_Face => FTC_Manager_LookupFace
+	      FTC_Manager_Lookup_Size => FTC_Manager_LookupSize (still in
+	      private header for the moment)

+	Use AS_HELP_STRING in AC_ARG_WITH.

+	<bird-freetype@anduin.net>.
+
+2003-06-30  Werner Lemberg  <wl@gnu.org>
+
+	A new try to synchronize bitmap font access.
+
+	* include/freetype/freetype.h (FT_Bitmap_Size): `height' is now
+	defined to return the baseline-to-baseline distance.  This was
+	already the value returned by the BDF and PCF drivers.
+
+	The `width' field now gives the average width.  I wasn't able to
+	find something better.  It should be taken as informative only.
+
+	New fields `size', `x_ppem', and `y_ppem'.
+
+	* src/pcf/pcfread.c (pcf_load_font): Updated to properly fill
+	FT_Bitmap_Size.

+
+2003-06-29  Werner Lemberg  <wl@gnu.org>
+
+	Redesigning the FNT driver to return multiple faces, not multiple
+	strikes.  At least one font (app850.fon from WinME) contains
+	different FNT charmaps for its subfonts.  Consequently, the previous
+	design of having multiple bitmap strikes in a single font face fails
+	since we have only one charmap per face.
+
+	* include/freetype/internal/fnttypes.h (FNT_Size_Rec): Removed.
+	(FNT_FaceRec): Remove `num_fonts' field and replace `fonts' with

+	(FNT_Face_Init): Handle `face_index'.
+	Updated.
+	(FNT_Size_Set_Pixels): Simplified; similar to BDF and PCF, the
+	bitmap width is now ignored.
+	(FNT_Load_Glyph): Updated.
+	Fix glyph index computation.
+	(winfnt_driver_class): Updated.
+
+2003-06-25  Owen Taylor  <otaylor@redhat.com>
+
+	* src/sfnt/ttload.c (tt_face_load_hdmx): Don't assign

+
+2003-06-24  Werner Lemberg  <wl@gnu.org>

+
+	* src/winfonts/winfnt.c (FNT_Load_Glyph): Use first_char in

+	Without this fix it isn't possible to access all strikes.
+	Also compute metrics.max_advance to be in sync with other bitmap
+	drivers.
+
+	* src/base/ftobjs.c (FT_Set_Char_Size): Remove redundant code.

+
+2003-06-20  Werner Lemberg  <wl@gnu.org>
+
+	Synchronize computation of height and width for bitmap strikes.  The
+	`width' field in the FT_Bitmap_Size structure is now only useful to
+	enumerate different strikes.  The `max_advance' field of the
+	FT_Size_Metrics structure should be used to get the (maximum) width
+	of a strike.
+
+	* src/bdf/bdfdrivr.c (BDF_Face_Init): Don't use AVERAGE_WIDTH for
+	computing `available_sizes->width' but make it always equal to
+	`available_sizes->height'.
+
+	* src/pcf/pcfread.c (pcf_load_font): Don't use RESOLUTION_X for
+	computing `available_sizes->width' but make it always equal to
+	`available_sizes->height'.
+
+	* src/truetype/ttdriver.c (Set_Pixel_Sizes): Pass only single
+	argument to function.
+
+	* src/psnames/psmodule.c (ps_unicode_value): Handle `.' after

+
+	* include/freetype/config/ftoption.h: Defining

+	Implement unpatented hinting.
+	(DO_SPVTCA, DO_SFVTCA, DO_SPVTL, DO_SFVTL, DO_SPVFS, DO_SFVFS,
+	Ins_SDPVTL): Call `GUESS_VECTOR'.
+	(DO_GPV, DO_GFV) [TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING]:
+	Handle `unpatented_hinting'.
+	(Compute_Point_Displacement) [NO_APPLE_PATENT]: Removed.

+	hinting.
+	(Move_Zp2_Point, Ins_SHPIX, Ins_DELTAP, Ins_DELTAC)
+	[TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING]: Implement unpatented
+	hinting.
+	(TT_RunIns): Updated.
+
+	* src/truetype/ttobjs.c
+	[TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING]: Include
+	FT_TRUETYPE_UNPATENTED_H.
+	(tt_face_init) [TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING,
+	TT_CONFIG_OPTION_FORCE_UNPATENTED_HINTING]: Check
+	FT_PARAM_TAG_UNPATENTED_HINTING.
+
+	* src/truetype/ttobjs.h (TT_GraphicsState)
+	[TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING]: Add `both_x_axis'.
+
+2003-04-25  Werner Lemberg  <wl@gnu.org>
+
+	* src/bdf/bdflib.c (hash_bucket, hash_lookup): Use `const' for first
+	argument.
+	(bdf_get_font_property): Use `const' for third argument.
+	Updated all callers.
+	* src/bdf/bdfdrivr.c (BDF_Face_Init): Set pixel width and height
+	similar to the PCF driver.
+	* src/bdf/bdf.h (_hashnode): Use `const' for `key'.
+	Updated.
+
+	* src/gzip/ftgzip.c: C++ doesn't like that the array `inflate_mask'
+	is declared twice.  It is perhaps better to modify the zlib source
+	files directly instead of this hack.
+	(zcalloc, zfree, ft_gzip_stream_close, ft_gzip_stream_io): Add casts
+	to make build with g++ successful.
+
+2003-04-24  Manish Singh  <yosh@gimp.org>
+
+	* src/cid/cidobjs.c (cid_face_init), src/type1/t1objs.c
+	(T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Split on `-'
+	also for searching the style name.
+
+2003-04-24  David Turner  <david@freetype.org>
+
+	* src/pcf/pcfread.c (pcf_load_font): Fixed the computation of
+	face->num_glyphs.  We must increase the value by 1 to respect the
+	convention that glyph index 0 always corresponds to the `missing
+	glyph'.
+
+2003-04-24  Werner Lemberg  <wl@gnu.org>
+
+	* builds/unix/unix-cc.in (CFLAGS): Add @CPPFLAGS@.
+
+2003-04-24  Dieter Baron  <dillo@netbsd.org>
+
+	* builds/unix/freetype-config.in (cflags): Emit FreeType 2's include
+	files first.  Otherwise there are conflicts with FreeType 1
+	installed simultaneously.
+
+2003-04-23  Werner Lemberg  <wl@gnu.org>
+
+	Fixing bugs reported by Nelson Beebe.
+

+
+	* src/sfnt/sfdriver.c (get_sfnt_postscript_name): Mark `error' as
+	unused.
+
+	* src/type1/t1objs.c (T1_Face_Init): Remove unused variable

+
+	* src/type1/t1gload.c (T1_Load_Glyph): Use `glyph_data_loaded'
+	only for FT_CONFIG_OPTION_INCREMENTAL.
+
+2003-04-23  Akito Hirai  <akito@kde.gr.jp>
+
+	* src/sfnt/ttcmap0.c (tt_cmap4_validate): Provide a weak variant
+	of the glyph ID bounding check if FT_VALIDATE_TIGHT is not active.
+	Without this change, many CJK fonts from Dynalab are rejected.
+
+2003-04-23  Joe Marcus Clarke  <marcus@FreeBSD.org>
+
+	* src/base/ftbdf.c (FT_Get_BDF_Property): Check for valid
+	`get_interface'.
+
+2003-04-23  Paul Miller  <paulm@profoundeffects.com>
+
+	* src/base/ftmac.c (parse_fond): Fix handling of style names.
+
+2003-04-23  Werner Lemberg  <wl@gnu.org>
+
+	* src/pfr/pfrload.c (pfr_extra_item_load_font_id): Use FT_PtrDist
+	instead of FT_UInt for `len'.
+
+2003-04-22  Werner Lemberg  <wl@gnu.org>
+
+	* src/gzip/ftgzip.c (zcalloc) [!FT_CONFIG_OPTION_SYSTEM_ZLIB]:
+	Convert K&R format to modern C usage.

+
+2003-04-21  Werner Lemberg  <wl@gnu.org>

+	bug that had nasty consequences when trying to open an `invalid'
+	font on a Mac.
+
+2003-04-09  Mike Fabian  <mfabian@suse.de>
+
+	* src/bdf/bdfdrivr.h (BDF_encoding_el), src/pcf/pcf.h
+	(PCF_EncodingRec): Changed FT_Short to FT_UShort in order to be able
+	to access more than 32768 glyphs in fonts.
+
+2003-04-08  David Turner  <david@freetype.org>
+
+
+	* Version 2.1.4 released.
+	=========================
+
+
+2003-04-03  Martin Muskens  <mmuskens@aurelon.com>
+
+	* src/type1/t1load.c (T1_Open_Face): Fixed the code to make it
+	handle special cases where a font only contains a `.notdef' glyph
+	(happens in PDF-embedded fonts).  Otherwise, FT_Panic was called.
+
+2003-03-27  David Turner  <david@freetype.org>
+
+	* README: Updated.
+
+	* README.UNX: Removed (now replaced by docs/INSTALL.UNX).
+
+	* src/pshinter/pshalgo3.c: The hinter now performs as in 2.1.3 and
+	will ignore stem quantization only when FT_LOAD_TARGET_SMOOTH is
+	used.
+	(psh3_dimension_quantize_len): Enabled.
+	(psh3_hint_align): Enable commented code.
+	(psh3_hint_align_light): Commented out.
+
+	* src/base/ftobjs.c (FT_Set_Char_Size): Changed the default
+	computations to include rounding in all cases; this is required to
+	provide accurate kerning data when native TrueType hinting is
+	enabled.
+
+	* src/type1/t1load.c (is_name_char): The Type 1 loader now accepts
+	more general names according to the PostScript specification (the
+	previous one was too restrictive).
+	(parse_font_name, parse_encoding, parse_charstrings, parse_dict):
+	Use `is_name_char'.
+	(parse_subrs): Handle empty arrays.
+
+2003-03-20  David Turner  <david@freetype.org>
+
+	Serious rewriting of the documentation.
+
+	* docs/BUGS, docs/BUILD: Removed.
+	* docs/DEBUG.TXT: Renamed to...
+	* docs/DEBUG: This.
+	* docs/CUSTOMIZE, docs/TRUETYPE, docs/UPGRADE.UNX: New files.
+	* docs/INSTALL.ANY, docs/INSTALL.UNX, docs/INSTALL.GNU New files,
+	containing platform specific information previously in INSTALL.
+	* docs/readme.vms: Renamed to...
+	* docs/INSTALL.VMS: This.
+
+	* docs/*: Updated.
+
+	Introduced three new functions to deal with glyph bitmaps within
+	FT_GlyphSlot objects:
+
+	  ft_glyphslot_free_bitmap
+	  ft_glyphslot_alloc_bitmap
+	  ft_glyphslot_set_bitmap
+
+	These functions are much more convenient to use than managing the
+	FT_GLYPH_OWN_BITMAP flag manually.
+
+	* include/freetype/internal/ftobjs.h (ft_glyphslot_free_bitmap,
+	ft_glyphslot_alloc_bitmap, ft_glyphslot_set_bitmap): New functions.
+	* src/base/ftobjs.c: Implement them.
+	(ft_glyphslot_done): Use ft_glyphslot_free_bitmap.
+
+	* src/bdf/bdfdrivr.c (BDF_Glyph_Load), src/pcf/pcfdriver.c
+	(PCF_Glyph_Load): Remove unused variable `memory'.
+	Use `ft_glyphslot_*' functions.
+	Don't set `FT_GLYPH_OWN_BITMAP'.
+
+	* src/pfr/pfrsbit.c (pfr_slot_load_bitmap): Use
+	`ft_glyphslot_alloc_bitmap'.
+
+	* src/sfnt/ttsbit.c (Load_SBit_Image): Change 5th argument to type
+	`FT_GlyphSlot'.
+	Adding argument `depth' to handle recursive calls.
+	Use `ft_glyphslot_alloc_bitmap'.
+	(tt_face_load_sbit_image): Remove unused variable `memory'.
+	Don't handle `FT_GLYPH_OWN_BITMAP'.
+	Update call to Load_SBit_Image.
+
+	* src/type42/t42objs.c (ft_glyphslot_clear): Renamed to...
+	(t42_glyphslot_clear): This.  Updated caller.
+	Call `ft_glyphslot_free_bitmap'.
+
+	* src/winfonts/winfnt.c (FNT_Load_Glyph): Use
+	`ft_glyphslot_set_bitmap'.
+	Don't handle `FT_GLYPH_OWN_BITMAP'.
+
+	* src/cache/ftlru.c (FT_LruList_Lookup): Fixed an invalid assertion
+	check.
+
+	* src/autohint/ahglyph.c (ah_outline_load): Add two scaling
+	arguments.
+	* src/autohint/ahglyph.h: Updated.
+	* src/autohint/ahhint.c (ah_hinter_load): Updated.
+	* src/autohint/ahglobal.c (ah_hinter_compute_widths): Updated.
+
+	* src/cache/ftccache.c (ftc_family_done): Fixed small bug that could
+	crash the cache in rare circumstances (mostly with broken fonts).
+
+2003-03-15  David Turner  <david@freetype.org>
+
+	* src/truetype/ttdriver.c (Set_Char_Sizes): Fixed a small rounding
+	bug.  Actually, it seems that previous versions of FreeType didn't
+	perform TrueType rounding exactly as appropriate.
+
+2003-03-14  David Turner  <david@freetype.org>
+
+	* src/truetype/ttdriver.c (Set_Char_Sizes): Fixing the small
+	TrueType native rendering glitches; they came from a small rounding
+	error.
+
+2003-03-13  David Turner  <david@freetype.org>
+
+	Added new environment variables to control memory debugging with
+	FreeType.  See the description of `FT2_DEBUG_MEMORY',
+	`FT2_ALLOC_TOTAL_MAX' and `FT2_ALLOC_COUNT_MAX' in DEBUG.TXT.
+
+	* src/base/ftdbgmem.c (FT_MemTableRec): Add `alloc_count',
+	`bound_total', `alloc_total_max', `bound_count', `alloc_count_max'.
+	(ft_mem_debug_alloc): Handle new variables.
+	(ft_mem_debug_init): s/FT_DEBUG_MEMORY/FT2_DEBUG_MEMORY/.
+	Handle new environment variables.
+	* docs/DEBUG.TXT: Updated.
+
+	Fixed the cache sub-system to correctly deal with out-of-memory
+	conditions.
+
+	* src/cache/ftccache.c (ftc_node_destroy): Comment out generic
+	check.
+	(ftc_cache_lookup): Implement loop.
+	* src/cache/ftccmap.c: Define FT_COMPONENT.
+	* src/cache/ftcsbits.c (ftc_sbit_node_load): Handle
+	FT_Err_Out_Of_Memory.
+	* src/cache/ftlru.c: Include FT_INTERNAL_DEBUG_H.
+	(FT_LruList_Lookup): Implement loop.
+
+	* src/pfr/pfrobjs.c (pfr_face_done): Fix memory leak.
+	(pfr_face_init): Fixing compiler warnings.
+
+	* src/psaux/psobjs.c (reallocate_t1_table): Fixed a bug (memory
+	leak) that only happened when a try to resize an array would end in
+	an out-of-memory condition.
+
+	* src/smooth/ftgrays.c (gray_convert_glyph): Removed compiler
+	warnings / volatile bug.
+
+	* src/truetype/ttobjs.c (tt_glyphzone_done): Removed segmentation
+	fault that happened in tight memory environments.
+
+2003-02-28  Pixel  <pixel@mandrakesoft.com>
+
+	* src/gzip/ftgzip.c (ft_gzip_file_done): Fixed memory leak: The ZLib
+	stream was not properly finalized.
+
+2003-02-25  Anthony Fok  <anthony@thizlinux.com>
+
+	* src/cache/ftccmap.c: Include FT_TRUETYPE_IDS_H.
+	(ftc_cmap_family_init): The cmap cache now
+	supports UCS-4 charmaps when available in Asian fonts.
+
+	* src/sfnt/ttload.c, src/base/ftobjs.c: Changed `asian' to `Asian'
+	in comments.
+
+2003-02-25  David Turner  <david@freetype.org>
+
+	* src/gzip/ftgzip.c (ft_gzip_file_fill_output): Fixed a bug that
+	caused FreeType to loop endlessly when trying to read certain
+	compressed gzip files.  The following test reveals the bug:
+
+	  touch 0123456789 ; gzip 0123456789 ; ftdump 0123456789.gz
+
+	Several fixes to the PFR font driver:
+
+	- The list of available embedded bitmaps was not correctly set in
+	  the root FT_FaceRec structure describing the face.
+
+	- The glyph loader always tried to load the outlines when
+	  FT_LOAD_SBITS_ONLY was specified.
+
+	- The table loaded now scans for *undocumented* elements of a
+	  physical font's auxiliary data record.  This is necessary to
+	  retrieve the `real' family and style names.
+
+	NOTE THAT THESE CHANGES THE FAMILY NAME OF MANY PFR FONTS!
+
+	* src/pfr/pfrload.c (pfr_aux_name_load): New function.
+	(pfr_phy_font_done): Free `family_name' and `style_name' also.
+	Remove unused variables.
+	(pfr_phy_font_load): Extract useful information from the auxiliary
+	bytes.
+
+	* src/pfr/pfrobjs.c (pfr_face_done): Set pointers to NULL.
+	(pfr_face_init): Provide fallback values for `family_name' and
+	`style_name'.
+	Handle strikes.
+	(pfr_slot_load): Handle FT_LOAD_SBITS_ONLY.
+	* src/pfr/pfrtypes.h (PFR_PhyFontRec): Add fields `ascent',
+	`descent', `leading', `family_name', and `style_name'.
+
+	* src/truetype/ttdriver.c (Set_Char_Sizes): Fixed a rounding bug
+	when computing the scale factors for a given character size in
+	points with resolution.
+
+	* devel/ft2build.h, devel/ftoption.h: New files (in a new directory)
+	which are special development versions of include/ft2build.h and
+	include/freetype/config/ftoption.h, respectively.
+
+2003-02-18  David Turner  <david@freetype.org>
+
+	Fixing the slight distortion problem that occurred due to the latest
+	auto-hinter changes.
+
+	* src/base/ftobjs.c (ft_recompute_scaled_metrics): Fix rounding.
+
+	* src/truetype/ttdriver.c (Set_Char_Sizes): New variable `metrics2'.
+	[!TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Removed.
+
+	* src/truetype/ttobjs.h (TT_SizeRec): New field `metrics'.
+	* src/truetype/ttobjs.c (Reset_Outline_Size): Fix initialization of
+	`metrics'.
+	[FT_CONFIG_CHESTER_ASCENDER]: Code removed.
+	(Reset_SBit_Size): Fix initialization of `metrics'.
+
+	* src/truetype/ttinterp.c (TT_Load_Context): Fix initialization of
+	`exec->metrics'.
+
+	* src/autohint/ahhint.c (ah_hinter_load): Disabled the advance width
+	`correction' which seemed to provide more trouble than benefits.
+
+2003-02-13  Graham Asher  <graham.asher@btinternet.com>
+
+	Changed the incremental loading interface in a way that makes it
+	simpler and allows glyph metrics to be changed (e.g., by adding a
+	constant, as required by CFF fonts) rather than just overridden.
+	This was required to make the GhostScript-to-FreeType bridge work.
+
+	* src/cff/cffgload.c (cff_slot_load) [FT_CONFIG_OPTION_INCREMENTAL]:
+	Allow metrics to be overridden.
+	* src/cid/cidgload.c (cid_load_glyph) [FT_CONFIG_OPTION_INCREMENTAL]:
+	Ditto.
+
+	* src/truetype/ttgload.c (load_truetype_glyph)
+	[FT_CONFIG_OPTION_INCREMENTAL]: Simplify.
+	(compute_glyph_metrics) [FT_CONFIG_OPTION_INCREMENTAL]: Code block
+	moved down.
+
+	* src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String)
+	[FT_CONFIG_OPTION_INCREMENTAL]: Updated.
+
+	* include/freetype/ftincrem.h: Updated.
+
+2003-01-31  David Turner  <david@freetype.org>
+
+	* docs/CHANGES, docs/VERSION.DLL, docs/TODO: Updating documentation
+	for the 2.1.4 release.
+
+	* builds/win32/visualc/freetype.dsp,
+	builds/win32/visualc/index.html: Updating the project file for
+	2.1.4.
+
+	* src/gzip/adler32.c, src/gzip/ftgzip.c, src/gzip/infblock.c,
+	src/gzip/infcodes.c, src/gzip/inflate.c, src/gzip/inftrees.c,
+	src/gzip/infutil.c: Removed old-style (K&R)function definitions.
+	This avoids warnings with Visual C++ at its most pedantic mode.
+
+	* src/pfr/pfrsbit.c: Removed compiler warnings.
+
+	* src/cache/ftccmap.c (ftc_cmap_family_init): Changed an FT_ERROR
+	into an FT_TRACE1 since it caused `ftview' and others to dump too
+	much junk when trying to display a waterfall with a font without a
+	Unicode charmap (e.g.  SYMBOL.TTF).
+
+	Implemented FT_CONFIG_CHESTER_BLUE_SCALE, corresponding to the last
+	patch from David Chester, but with a much simpler (and saner)
+	implementation.
+
+	* src/autohint/ahhint.c (ah_hinter_load_glyph)
+	[FT_CONFIG_CHESTER_BLUE_SCALE]: Try to optimize the y_scale so that
+	the top of non-capital letters is aligned on a pixel boundary
+	whenever possible.
+
+	* src/base/ftobjs.c (FT_Set_Char_Size)
+	[FT_CONFIG_CHESTER_BLUE_SCALE]: Round differently.
+	* src/truetype/ttdriver.c (Set_Char_Sizes)
+	[TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Do some rounding only
+	if this macro is defined.
+
+	* src/truetype/ttobjs.c (Reset_Outline_Size)
+	[FT_CONFIG_CHESTER_ASCENDER]: Round differently.
+
+	* src/pshinter/pshalgo3.c: Improved the Postscript hinter.  Getting
+	rid of stem snapping seems to work well here (though the stems are
+	still slightly moved to increase contrast).
+	(psh3_dimension_quantize_len): Commented out.
+	(psh3_hint_align_light): New function.
+	(psh3_hint_align): Comment out some code.
+
+	THIS IMPROVES ANTI-ALIASED RENDERING, BUT MONOCHROME AND LCD MODES
+	STILL SUCK.
+
+2003-01-22  David Chester  <davidchester@qmx.net>
+
+	* src/autohint/ahhint.c (ah_compute_stem_width): Small fix to the
+	stem width optimization.
+
+2003-01-22  David Turner  <david@freetype.org>
+
+	Adding a new API `FT_Get_BDF_Property' to retrieve the BDF
+	properties of a given PCF or BDF font.
+
+	* include/freetype/ftbdf.h (BDF_PropertyType): New enumeration.
+	(BDF_Property, BDF_PropertyRec): New structure.

+	(BDF_GetPropertyFunc): New function pointer.
+
+	* src/base/ftbdf.c (test_font_type): New helper function.

+
+	* src/pcf/pcfdrivr.c: Include FT_BDF_H.
+	(pcf_get_bdf_property, pcf_driver_requester): New functions
+	(pcf_driver_class): Use `pcf_driver_requester'.
+
+	* src/pcf/pcfread.c: Include `pcfread.h'.
+	(pcf_find_property): Decorate it with FT_LOCAL_DEF.
+	* src/pcf/pcfread.h: New file, providing `pcf_find_property'.
+
+	* src/sfnt/ttload.c (sfnt_dir_check): Relaxed the `head' table size
+	verification to accept a few broken fonts who pad the size
+	incorrectly (the table should be padded, but its `size' field
+	shouldn't according to the specification).
+
+2003-01-18  Werner Lemberg  <wl@gnu.org>
+
+	* builds/unix/ltmain.sh: Regenerated with `libtoolize --force
+	--copy' from libtool 1.4.3.
+	* builds/unix/aclocal.m4: Regenerated with `aclocal -I .' from
+	automake 1.7.1.
+	* builds/unix/configure: Regenerated with autoconf 2.54.
+	* builds/unix/config.guess, builds/unix/config.sub: Updated from
+	`config' CVS module at subversions.gnu.org.
+	* builds/unix/install-sh, builds/unix/mkinstalldirs: Updated from

+	FT_Size_Metrics.
+
+2003-01-15  James Su  <suzhe@turbolinux.com.cn>
+
+	* src/gzip/ftgzip.c (ft_gzip_check_header): Bugfix: couldn't read
+	certain gzip-ed font files (typo: `&&' -> `&').
+
+2003-01-15  Huw D M Davies  <h.davies1@physics.ox.ac.uk>
+
+	Added a Windows .FNT specific API (mostly for Wine).  Also fixed a
+	nasty bug in the header loader which would cause invalid memory
+	overwrites.
+
+	* include/freetype/config/ftheader.h (FT_WINFONTS_H): New macro
+	for ftwinfnt.h.
+	* include/freetype/internal/fnttypes.h: Include FT_WINFONTS_H.

+	* src/base/Jamfile, src/base/descrip.mms, src/base/rules.mk:
+	Updated.
+
+2003-01-14  Graham Asher  <graham.asher@btinternet.com>
+
+	* include/freetype/ftglyph.h, src/base/ftglyph.c: Added `const' to
+	the type of the first argument to FT_Matrix_Multiply, which isn't
+	changed -- this adds documentation and convenience.
+
+2003-01-13  Graham Asher  <graham.asher@btinternet.com>
+
+	* src/sfnt/ttload.c (tt_face_load_metrics)
+	[FT_CONFIG_OPTION_INCREMENTAL]: TrueType typefaces without
+	horizontal metrics (without the `hmtx' table) are now tolerated if
+	an incremental interface has been specified that has a
+	get_glyph_metrics function, implying that metrics will be supplied
+	from outside.  This happens for certain Type 42 fonts passed from
+	GhostScript.
+
+2003-01-11  David Chester  <davidchester@qmx.net>
+
+	Patches to the auto-hinter in order to slightly improve the output.
+	Note that everything is controlled through the new
+	FT_CONFIG_OPTION_CHESTER_HINTS defined in `ftoption.h'.  There are
+	also individual FT_CONFIG_CHESTER_XXX macros to control individual
+	`features'.
+
+	Note that all improvements are enabled by default, but can be
+	tweaked for optimization and testing purposes.  The configuration
+	macros will most likely disappear in the short future.
+
+	* include/freetype/config/ftoption.h
+	(FT_CONFIG_OPTION_CHESTER_HINTS): New macro.
+	(FT_CONFIG_CHESTER_{SMALL_F,ASCENDER,SERIF,STEM,BLUE_SCALE})
+	[FT_CONFIG_OPTION_CHESTER_HINTS]: New macros to control individual
+	features.
+
+	* src/autohint/ahglobal.c (blue_chars) [FT_CONFIG_CHESTER_SMALL_F]:

+	[FT_CONFIG_CHESTER_SMALL_F]: Use `AH_BLUE_SMALL_F_TOP'.
+	* src/autohint/ahglyph.c (ah_outline_compute_edges)
+	[FT_CONFIG_CHESTER_SERIF]: Use `AH_EDGE_SERIF'.
+	(ah_outline_compute_blue_edges) [FT_CONFIG_CHESTER_SMALL_F]:
+	Increase threshold for `best_dist'.
+	* src/autohint/ahhint.c (ah_compute_stem_width)
+	[FT_CONFIG_CHESTER_SERIF]: Provide new version for improved serif
+	handling.
+	(ah_align_linked_edge) [FT_CONFIG_CHESTER_SERIF]: Use special
+	version of `ah_compute_stem_width'.
+	(ah_hint_edges_3) [FT_CONFIG_CHESTER_STEM]: A new algorithm for stem
+	alignment when stem widths are less than 1.5 pixels wide centers the
+	stem slightly off-center of the center of a pixel (this increases
+	sharpness and consistency).
+	[FT_CONFIG_CHESTER_SERIF]: Use special version of
+	`ah_compute_stem_width'.
+	* src/autohint/ahtypes.h [FT_CONFIG_CHESTER_SMALL_F]: Add
+	`AH_BLUE_SMALL_F_TOP'.
+
+2003-01-11  David Turner  <david@freetype.org>
+
+	* include/freetype/internal/fnttypes.h (WinFNT_HeaderRec): Increase
+	size of `reserved2' to avoid memory overwrites.
+
+2003-01-08  Huw Davies  <huw@codeweavers.com>
+
+	* src/winfonts/winfnt.c (winfnt_header_fields): Read 16 bytes into
+	`reserved2', not `reserved'.
+
+	* src/base/ftobjs.c (find_unicode_charmap): Fixed the error code
+	returned when the font doesn't contain a Unicode charmap.  This
+	allows FT2 to load `symbol.ttf' and a few others correctly since the
+	last release.
+	(open_face): Fix return value.
+
+2003-01-08  Owen Taylor  <owen@redhat.com>
+
+	Implemented the FT_RENDER_MODE_LIGHT hinting mode in the auto and
+	postscript hinters.
+
+	* src/autohint/ahtypes.h (AH_HinterRec): Add `do_stem_adjust'.
+	* src/autohint/ahhint.c (ah_compute_stem_width): Handle
+	hinter->do_stem_adjust.
+	(ah_hinter_load_glyph): Set hinter->do_stem_adjust.
+
+	* src/pshinter/pshalgo3.h (PSH3_GlyphRec): Add `do_stem_adjust'.
+	* src/pshinter/pshalgo3.c (psh3_hint_align): Use `do_stem_adjust'.
+	(ps3_hints_apply): Handle FT_RENDER_MODE_LIGHT.
+
+	* include/freetype/freetype.h (FT_Render_Mode): Add
+	FT_RENDER_MODE_LIGHT.
+
+	* src/truetype/ttgload.c: Fixing the TrueType loader to handle
+	invalid composites correctly by limiting the recursion depth.
+	(TT_MAX_COMPOSITE_RECURSE): New macro.
+	(load_truetype_glyph): Add argument `recurse_count'.
+	Load a composite only if the numbers of contours is -1, emit error
+	otherwise.
+	(TT_Load_Glyph): Updated.
+
+2003-01-08  David Turner  <david@freetype.org>
+
+	* Jamrules, Jamfile, Jamfile.in, src/*/Jamfile: Small changes to
+	support the compilation of FreeType 2 as part of larger projects
+	with their own configuration options (only with Jam).
+
+2003-01-07  David Turner  <david@freetype.org>
+
+	* src/base/ftstroker.c: Probably the last bug-fixes to the stroker;
+	the API is likely to change, however.
+	(ft_stroke_border_close): Don't record empty paths.
+	(ft_stroke_border_get_counts): Increase `num_points' also in for loop.
+	(ft_stroke_border_export): Don't increase `write' twice in for loops.
+	(ft_stroker_outside): Handle `phi' together with `theta'.
+	(FT_Stroker_ParseOutline): New function.
+
+	* src/base/fttrigon.c (FT_Angle_Diff): Fixing function: It returned
+	invalid values for large negative angle differences (resulting in
+	incorrect stroker computations, among other things).
+
+	* src/cache/ftccache.c (ftc_node_hash_unlink): Removing incorrect
+	assertion, and changing code to avoid hash table size contraction.
+
+	* src/base/Jamfile, src/base/rules.mk, src/base/descrip.mms: Adding
+	`ftstroker' to default build, as optional component.
+
+2002-12-26  David Turner  <david@freetype.org>
+
+	* src/gzip/adler32.c, src/gzip/infblock.c, src/gzip/inflate.c,
+	src/gzip/inftrees.c, src/gzip/zconf.h, src/gzip/zlib.h,
+	src/gzip/zutil.h: Updates to allow compilation without compiler
+	warnings with LCC-Win32.
+
+	* include/freetype/freetype.h (FREETYPE_PATCH): Set to 4.
+	* builds/unix/configure.ac (version_info): Increased to 9:3:3.
+	* builds/unix/configure: Regenerated.

+
+	* include/freetype/internal/sfnt.h (SFNT_Load_Table_Func): New

+	well as providing an autoconf fragment provided by Lars Clausen.
+
+	* src/smooth/ftgrays.c (gray_render_conic): Fixed small bug that
+	prevented Bézier arcs with negative vertical coordinates to be
+	rendered appropriately.
+
+2002-12-02  Antoine Leca  <Antoine-Freetype@Leca-Marti.org>
+
+	* src/base/ftobjs.c: Modified the logic to get Unicode charmaps.
+	Now it loads UCS-4 charmaps when there is one.
+	(find_unicode_charmap): New function.
+	(open_face): Refer to the above one.
+	(FT_Select_Charmap): Idem.
+
+2002-11-29  Antoine Leca  <Antoine-Freetype@Leca-Marti.org>
+
+	* include/freetype/ftgzip.h: Correct the name of the controlling
+	macro (was __FTXF86_H__ ...).
+
+2002-11-27  Vincent Caron  <v.caron@zerodeux.net>
+
+	* builds/unix/unix-def.in, builds/unix/freetype-config.in,
+	builds/unix/configure.ac, src/gzip/rules.mk, src/gzip/ftgzip.c
+	[FT_CONFIG_OPTION_SYSTEM_ZLIB]: Adding support for system zlib
+	installations if available on the target platform (Unix only).
+
+2002-11-23  David Turner  <david@freetype.org>
+
+	* src/cff/cffload.c (cff_charset_load, cff_encoding_load): Modified
+	charset loader to accept pre-defined charsets, even when the font
+	contains fewer glyphs.  Also enforced more checks to ensure that we
+	never overflow the character codes array in the encoding.
+
+2002-11-22  Antoine Leca  <Antoine-Freetype@Leca-Marti.org>
+
+	* include/freetype/ttnameid.h: Updated to latest OpenType
+	specification.
+
+2002-11-18  David Turner  <david@freetype.org>
+
+
+	* Version 2.1.3 released.
+	=========================
+
+
+2002-11-07  David Turner  <david@freetype.org>
+
+	* src/cache/ftcsbits.c (ftc_sbit_node_load): Fixed a small bug that
+	caused problems with embedded bitmaps.
+
+	* src/otlayout/otlayout.h, src/otlayout/otlconf.h,
+	src/otlayout/otlgsub.c, src/otlayout/otlgsub.h,
+	src/otlayout/otlparse.c, src/otlayout/otlparse.h,
+	src/otlayout/otlutils.h: Updating the OpenType Layout code, adding
+	support for the first GSUB lookups.  Nothing that really compiles
+	for now though.
+
+	* src/autohint/ahhint.c (ah_align_serif_edge): Disabled serif stem
+	width quantization.  It produces slightly better shapes though this
+	is not distinguishable with many fonts.
+	Remove other dead code.
+
+	* src/Jamfile, src/*/Jamfile: Simplified.
+	Use $(FT2_SRC_DIR).
+
+2002-11-06  David Turner  <david@freetype.org>
+
+	* include/freetype/freetype.h (FT_LOAD_TARGET_LIGHT): New macro.
+	(FT_LOAD_TARGET, FT_LOAD_TARGET_MODE): Use `& 15' instead of `& 7'.
+
+2002-11-05  David Turner  <david@freetype.org>
+
+	* include/freetype/config/ftoption.h, src/gzip/ftgzip.c: Added
+	support for the FT_CONFIG_OPTION_SYSTEM_ZLIB option, used to specify
+	the use of system-wide zlib.
+
+	Note that this macro, as well as
+	TT_CONFIG_OPTION_BYTECODE_INTERPRETER, is not #undef-ed anymore.
+	This allows the build system to define them depending on the
+	configuration (typically by adding -D flags at compile time).
+
+	* src/sfnt/ttcmap0.c (tt_face_build_cmaps): Removed compiler
+	warnings in optimized mode relative to the `volatile' local
+	variables.  This was not a compiler bug after all, but the fact that
+	a pointer to a volatile variable is not the same as a volatile
+	pointer to a variable :-)
+
+	The fix was to change
+	  `volatile FT_Byte* p'
+	into
+	  `FT_Byte* volatile p'.
+
+	* src/pfr/pfrload.c (pfr_phy_font_load), src/pfr/pfrdrivr.c
+	(pfr_get_metrics), src/gzip/inftrees.c: Removed compiler warnings in
+	optimized modes.
+
+	* src/gzip/*.[hc]: Modified our zlib copy in order to prevent
+	exporting any zlib function names outside of the component.  This
+	prevents linking problems on some platforms, when applications want
+	to link FreeType _and_ zlib together.
+
+2002-11-05  Juliusz  <jch@pps.jussieu.fr>
+
+	* src/psaux/psobjs.c (ps_table_add): Modified increment loop in
+	order to implement exponential behaviour.
+
+2002-11-01  David Turner  <david@freetype.org>
+
+	Added PFR-specific public API.  Fixed the kerning retrieval routine
+	(it returned invalid values when the outline and metrics resolution
+	differ).
+
+	* include/freetype/ftpfr.h, include/freetype/internal/pfr.h: New
+	files.
+
+	* include/freetype/internal/internal.h (FT_INTERNAL_PFR_H): New
+	macro for pfr.h.

+	(pfr_get_kerning, pfr_get_advance, pfr_get_metrics): New functions.
+	(pfr_service_rec): New format interface.
+	(pfr_driver_class): Use `pfr_service_rec'.
+	Replace `pfr_face_get_kerning' with `pfr_get_kerning'.
+	* src/pfr/pfrobjs.c: Remove dead code.
+
+	* src/base/ftobjs.c (ft_glyphslot_clear): Small internal fix to
+	better support bitmap-based font formats.
+
+	* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Fix handling of
+	`scale'.
+	Fix arguments to `FT_Vector_From_Polar'.
+
+2002-10-31  David Turner  <david@freetype.org>
+
+	Add support for automatic handling of gzip-compressed PCF files.
+
+	* src/gzip/*: New files, taken from the zlib package (except
+	ftgzip.c).
+
+	* include/freetype/ftgzip.h, src/gzip/ftgzip.c: New files.
+	* include/freetype/config/ftheader.h (FT_GZIP_H): New macro for
+	`ftgzip.h'.
+
+	* src/pcf/pcfdriver.c: Include FT_GZIP_H and FT_ERRORS_H.
+	(PCF_Face_Init): If normal open fails, try to open gzip stream.
+	(PCF_Face_Done): Close gzip stream.
+
+	* include/freetype/internal/pcftypes.h (PCF_Public_FaceRec),
+	src/pcf/pcf.h (PCF_FaceRec): Add `gzip_stream' and `gzip_source'.
+
+	* include/freetype/config/ftoption.h (FT_CONFIG_OPTION_USE_ZLIB):
+	New macro.
+	(T1_CONFIG_OPTION_DISABLE_HINTER, FT_CONFIG_OPTION_USE_CMAPS
+	FT_CONFIG_OPTION_NO_CONVENIENCE_FUNCS,
+	FT_CONFIG_OPTION_ALTERNATE_GLYPH_FORMATS): Removed.
+
+	(FT_EXPORT, FT_EXPORT_DEF, FT_DEBUG_LEVEL_ERROR,
+	FT_DEBUG_LEVEL_TRACE, FT_DEBUG_MEMORY): Comment out definitions so
+	that platform specific configuration file can override.
+
+	* include/freetype/internal/ftstream.h: Include FT_SYSTEM_H.
+
+2002-10-30  David Turner  <david@freetype.org>
+
+	* FreeType 2.1.3rc3 released.
+
+2002-10-25  David Turner  <david@freetype.org>
+
+	* include/freetype/ftcache.h (FT_POINTER_TO_ULONG): New macro.

+
+2002-10-22  Giuseppe Ghibò  <ghibo@mandrakesoft.com>

+	* include/freetype/freetype.h (FT_Encoding): Fix entry for latin-2.
+
+2002-10-07  Werner Lemberg  <wl@gnu.org>
+
+	* include/freetype/freetype.h (FT_Open_Face): Use `const' for `args'
+	(suggested by Graham).
+	* src/base/ftobjs.c (FT_Open_Face): Updated.
+	(ft_input_stream_new): Ditto.
+
+2002-10-05  David Turner  <david@freetype.org>
+
+	Adding support for embedded bitmaps to the PFR driver, and rewriting
+	its kerning loader/handler to use all kerning pairs in a physical
+	font (and not just the first item).
+
+	* src/pfr/pfr.c: Include `pfrsbit.c'.
+	* src/pfr/pfrgload.c: Include `pfrsbit.h'.

+	Load embedded bitmaps only if FT_LOAD_NO_BITMAP isn't set.
+
+	* src/tools/docmaker/content.py, src/tools/docmaker/sources.py,
+	src/tools/docmaker/tohtml.py: Fixing a few nasty bugs.
+
+	* src/sfnt/ttcmap0.c (tt_cmap4_validate): The validator for format 4
+	sub-tables is now capable of dealing with invalid `length' fields at
+	the start of the sub-table.  This allows fonts like `mg______.ttf'
+	(i.e.  Marriage) to return accurate charmaps.
+
+	* docs/CHANGES: Updated.
+
+2002-10-05  Werner Lemberg  <wl@gnu.org>
+
+	* src/smooth/ftgrays.c (SUBPIXELS): Add cast to `TPos'.

+
+	* include/freetype/freetype.h: Corrected the definition of

+	the erroneous FT_ENCODING_SYMBOL).
+
+	* builds/unix/unix-def.in (datadir): Initialize it (thanks to
+	Anthony Fok).
+
+2002-08-29  David Turner  <david@freetype.org>
+
+	Slight modification to the Postscript hinter to slightly increase
+	the contrast of smooth hinting.  This is very similar to what the
+	auto-hinter does when it comes to stem width computations.  However,
+	it produces better results with well-hinted fonts.
+
+	* include/freetype/internal/psaux.h (T1_Decoder_FuncsRec): Add hint
+	mode to `init' member function.
+	(T1_DecoderRec): Add hint mode.

+	Implement announced changes.
+	* src/pshinter/pshalgo3.h (PSH3_GlyphRec): Add flags to control
+	vertical and horizontal hints and snapping.
+
+	* README, docs/CHANGES: Updating for the 2.1.3 release.
+
+2002-08-27  David Turner  <david@freetype.org>
+
+	* Massive re-formatting changes to many, many source files.  I don't
+	want to list them all here.  The operations performed were all
+	logical transformations of the sources:
+
+	- trying to convert all enums and constants to CAPITALIZED_STYLE,
+	  #with define definitions like
+
+	    #define my_old_constants   MY_NEW_CONSTANT
+
+	- big, big update of the documentation comments
+
+	* include/freetype/freetype.h, src/base/ftobjs.c,
+	src/smooth/ftsmooth.c, include/freetype/ftimage.h: Adding support
+	for LCD-optimized rendering though the new constants/enums:
+
+	  FT_RENDER_MODE_LCD, FT_RENDER_MODE_LCD_V
+	  FT_PIXEL_MODE_LCD,  FT_PIXEL_MODE_LCD_V
+
+	This is still work in progress, don't expect everything to work
+	correctly though most of the features have been implemented.
+
+	* Adding new FT_LOAD_XXX flags, used to specify both hinting and
+	rendering targets:
+
+	  FT_LOAD_TARGET_NORMAL :: anti-aliased hinting & rendering
+	  FT_LOAD_TARGET_MONO   :: monochrome bitmaps
+	  FT_LOAD_TARGET_LCD    :: horizontal RGB/BGR decimated
+	                           hinting & rendering
+	  FT_LOAD_TARGET_LCD_V  :: vertical RGB/BGR decimated
+	                           hinting & rendering
+
+	Note that FT_LOAD_TARGET_NORMAL is 0, which means that the default
+	behaviour of the font engine is _unchanged_.
+
+	* include/freetype/ftimage.h
+	(FT_Outline_{Move,Line,Conic,Cubic}To_Func): Renamed to...
+	(FT_Outline_{Move,Line,Conic,Cubic}ToFunc): This.

+	have been updated accordingly.
+
+	* src/cff/cffgload.c (cff_decoder_init): Add hint mode as parameter.

+2002-08-23  Graham Asher  <graham.asher@btinternet.com>
+
+	* src/cff/cffgload.c (cff_operator_seac)
+	[FT_CONFIG_OPTION_INCREMENTAL]: Incremental fonts (actually not
+	incremental in the case of CFF but just using callbacks to get glyph
+	recipes) pass the character code, not the glyph index, to the
+	get_glyph_data function; they have no valid charset table.
+
+	* src/cff/cffload.c (cff_font_load): Removed special cases for
+	FT_CONFIG_OPTION_INCREMENTAL, which are no longer necessary; CFF
+	fonts provided via the incremental interface now have to conform
+	more closely to the CFF font format.
+
+	* src/cff/cffload.h (cff_font_load): Removed argument now unneeded.
+
+	* src/cff/cffobjs.c (cff_face_init): Changed call to cff_font_load

+	compiler warnings and resolve shadowing of local variables.
+
+2002-08-21  David Turner  <david@freetype.org>
+
+	The automatic and Postscript hinter now automatically detect
+	inflection points in glyph outlines and treats them specially.  This
+	is very useful to prevent nasty effect like the disappearing
+	diagonals of `S' and `s' in many, many fonts.
+
+	* src/autohint/ahtypes.h (ah_flag_inflection): New macro.
+	* src/autohint/ahangles.c (ah_angle_diff): New function.

+
+	* include/freetype/freetype.h: Changing the type of the `load_flags'
+	parameter from `FT_Int' to `FT_Int32', this in order to support more
+	options.  This should only break binary and/or source compatibility
+	on 16-bit platforms (Atari?).
+	(FT_LOAD_NO_AUTOHINT): New macro.
+
+	* src/base/ftobjs.c (FT_Load_Glyph): Updated.

+	New macros.
+	(PSH3_PointRec): New members `flags2' and `org_v'.
+	(PSH3_POINT_EQUAL_ARG, PSH3_POINT_ANGLE): New macros.
+

+
+2002-08-01  Graham Asher  <graham.asher@btinternet.com>
+
+	* src/type1/t1load.c (T1_Open_Face): Tolerate a face with no
+	charstrings if there is an incremental loading interface.  Type 1
+	faces supplied by PostScript interpreters like GhostScript will
+	typically not provide any charstrings at load time, so this is
+	essential if they are to work.
+
+2002-08-01  Graham Asher  <graham.asher@btinternet.com>
+
+	Modified incremental loading interface to be closer to David's
+	preferences.  The header freetype.h is not now affected, the
+	interface is specified via an FT_Parameter, the pointer to the
+	interface is hidden in an internal part of the face record, and all
+	the definitions are in ftincrem.h.

+	Removed.

+2002-07-24  Graham Asher  <graham.asher@btinternet.com>
+
+	* src/truetype/ttobjs.c: Fix for bug reported by Sven Neumann
+	[sven@gimp.org] on the FreeType development forum: `If

+	TrueType loader crashes in line 852 of src/truetype/ttgload.c when
+	it tries to access face->glyph_locations.'
+
+2002-07-18  Graham Asher  <graham.asher@btinternet.com>
+
+	Added types and structures to support incremental typeface loading.
+	The FT_Incremental_Interface structure, defined in freetype.h, is
+	designed to be passed to FT_Open_Face to provide callback functions
+	to obtain glyph recipes and metrics, for fonts like those passed
+	from PostScript that do not necessarily provide all, or any, glyph
+	information, when first opened.
+
+	* include/freetype/config/ftoption.h (FT_CONFIG_OPTION_INCREMENTAL):
+	New configuration macro to enable incremental face loading.  By
+	default it is not defined.

+	system for the TrueType driver.
+
+	* src/cid/cidgload.c (cid_load_glyph)
+	[FT_CONFIG_OPTION_INCREMENTAL]: Added the incremental loading system
+	for the CID driver.
+
+	* src/sfnt/sfobjs.c (SFNT_Load_Face) [FT_CONFIG_OPTION_INCREMENTAL]:
+	Changes to support incremental Type 42 fonts: Assume a font has
+	glyphs if it has an incremental interface object.
+
+	* src/type1/t1gload.c (T1_Parse_Glyph): Renamed to...
+	(T1_Parse_Glyph_And_Get_Char_String): This.

+
+2002-07-11  David Turner  <david@freetype.org>

+
+2005-05-28  David Turner  <david@freetype.org>
+
+	* docs/CHANGES: Updating file for next release (2.1.1).
+
+	* src/bdf/bdflib.c: Removing compiler warnings.
+
+	* include/freetype/ftxf86.h, src/base/ftxf86.c: New files.
+	They provide a new API (FT_Get_X11_Font_Format) to retrieve an
+	X11-compatible string describing the font format of a given face.
+	This was put in a new optional base source file, corresponding to a
+	new public header (named FT_XFREE86_H since this function should
+	only be used within the XFree86 font server IMO).
+
+	* include/freetype/config/ftheader.h (FT_XFREE86_H): New macro (not
+	documented yet).
+
+	* src/base/fttype1.c: New file, providing two new API functions
+	(FT_Get_PS_Font_Info and FT_Has_PS_Glyph_Names).
+	* include/freetype/t1tables.h: Updated.
+
+	* src/base/Jamfile, src/base/rules.mk, src/base/descrip.mms:
+	Updating build control files for the new files `ftxf86.c' and
+	`fttype1.c' in src/base.
+
+	* src/pshinter/pshglob.c (psh_blues_scale_zones): Fixed a bug that
+	prevented family blue zones substitution from happening correctly.
+

+
+2002-05-28  Werner Lemberg  <wl@gnu.org>

+	but FT_STREAM_READ.
+	Declare `stream' variable.
+
+	* src/bdf/bdflib.c (_bdf_parse_glyphs): Replace floating point math
+	with calls to `FT_MulDiv'.
+
+2002-05-28  David Turner  <david@freetype.org>
+
+	Fixing the SFNT name table loader to support various buggy fonts.
+	It now ignores empty name entries, entries with invalid pointer
+	Offsets and certain fonts containing tables with broken
+	`storageOffset' fields.
+
+	Name strings are now loaded on demand, which reduces the memory
+	requirements for a given FT_Face tremendously (for example, the name
+	table of Arial.ttf is about 10Kb and contains 70 names).
+
+	This is a temporary fix.  The whole name table loader and interface
+	will be rewritten in a much more cleanly way shortly, once CSEH have
+	been introduced in the sources.
+
+	* include/freetype/internal/tttypes.h (TT_NameEntryRec): Change
+	type of `stringOffset' to FT_ULong.
+	(TT_NameTableRec): Change type of `numNameRecords' and
+	`storageOffset' to FT_UInt.
+	Replace `storage' with `stream'.
+	* src/base/ftnames.c (FT_Get_Sfnt_Name): Load name on demand.
+	* src/sfnt/sfdriver.c (get_sfnt_postscript_name): Ditto.
+	Make code more robust.
+	* src/sfnt/sfobjs.c (TT_NameEntry_ConvertFunc): New typedef.
+	(tt_face_get_name): Use it.
+	Make code more robust.
+	* src/sfnt/ttload.c (TT_Load_Names): Use `static' for arrays.
+	Handle invalid `storageOffset' data better.
+	Set length fields to zero for invalid or ignored data.
+	Remove code within FT_DEBUG_LEVEL_TRACE.
+	(TT_Free_Names): Updated.
+
+2002-05-24  Tim Mooney  <enchanter@users.sourceforge.net>
+
+	* builds/unix/ft-munmap.m4: New file, extracted FT_MUNMAP_DECL and
+	FT_MUNMAP_PARAM from aclocal.m4 into here, so aclocal.m4 can be
+	rebuilt from sources.  Set macro serial to 1, and use third argument
+	to AC_DEFINE for our two custom symbols, so ftconfig.in could one day
+	be rebuilt with autoheader (not recommended now, ftconfig.in is a
+	custom source file)
+
+2002-05-22  Werner Lemberg  <wl@gnu.org>
+
+	* include/freetype/config/ftheader.h (FT_BEZIER_H): Removed.

+
+	* src/psaux/t1decode.c (T1_Decoder_Parse_Charstrings): Add dummy
+	for undocumented, obsolete opcode 15.
+
+2002-05-21  David Turner  <david@freetype.org>
+
+	* src/bdf/bdflib.c: Removed compiler warning, and changed all tables
+	to the `static const' storage specifier (instead of simply
+	`static').
+
+	* src/type42/t42drivr.c (hexval): Use more efficient code.
+	Removing compiler warnings.
+	* src/bdf/bdfdrivr.c: Removing compiler warnings.
+
+	* include/freetype/internal/ftbdf.h, src/base/ftbdf.c,
+	src/base/descrip.mms, src/base/Jamfile, src/base/rules.mk
+	(FT_Get_BDF_Charset_ID): New API to retrieve BDF-specific strings
+	from a face.  This is much cleaner than accessing the internal types
+	`BDF_Public_Face' defined in FT_INTERNAL_BDF_TYPES_H.
+
+2002-05-21  Werner Lemberg  <wl@gnu.org>
+
+	* src/bdf/README: Mention Microsoft's SBIT tool.

+	* include/freetype/internal/internal.h (FT_INTERNAL_T42_TYPES_H):
+	New macro.
+
+2002-05-20  Werner Lemberg  <wl@gnu.org>
+
+	* include/freetype/cache/ftcsbits.h (FTC_SBit): Added a new field
+	`num_grays' for specifying the number of used gray levels.
+	* src/cache/ftcsbits.c (ftc_sbit_node_load): Initialize it.
+
+2002-05-19  Werner Lemberg  <wl@gnu.org>
+
+	Adding a driver for BDF fonts written by Francesco Zappa Nardelli
+	<Francesco.Zappa.Nardelli@ens.fr>.  Heavily modified by me to

+
+2002-05-05  Werner Lemberg  <wl@gnu.org>
+
+	FreeType 2 can now be built in an external directory with the
+	configure script also.
+

+
+	* builds/unix/detect.mk (have_mk): New variable to test for
+	external build.
+	(unix-def.mk): Defined according to value of `have_mk'.
+	* builds/unix/unix.mk (have_mk): New variable to test for

+	(DISTCLEAN): Use it.
+	* builds/unix/unix-cc.in (LIBTOOL): Define default value only
+	if not yet defined.
+	* builds/unix/install.mk (install): Use `OBJ_BUILD' for installing
+	freetype-config.
+
+	* configure: Don't depend on bash features.

+	partially taken from Autoconf).
+	Build a dummy Makefile if not building in source tree.
+
+	* docs/INSTALL: Document it.
+
+2002-05-04  David Turner  <david@freetype.org>
+
+	* src/truetype/ttgload.c (TT_Load_Glyph): Finally fixing the last
+	bug that prevented FreeType 2.x and FreeType 1.x to produce
+	bit-by-bit identical monochrome glyph bitmaps with native TrueType
+	hinting.  The culprit was a single-bit flag that wasn't set
+	correctly by the TrueType glyph loader.
+
+	* src/otlayout/otlayout.h, src/otlayout/otlbase.c,
+	src/otlayout/otlbase.h, src/otlayout/otlconf.h,

+
+	* src/sfnt/ttcmap0.c (tt_cmap4_char_index): Fix serious typo

+	were opened.
+
+	* src/sfnt/ttload.c (TT_Load_Names): Applied a small work-around to
+	manage fonts containing a broken name table (e.g. `hya6gb.ttf').

+	* src/sfnt/ttcmap0.c (tt_cmap4_char_index): Switched to a binary
+	search algorithm.  Certain fonts contain more than 170 distinct
+	segments!

+	This is generic implementation of dynamic hash tables using a linear
+	algorithm (to get rid of `stalls' during resizes).  In the future
+	this will be used in at least three parts of the library: the cache
+	sub-system, the object sub-system, and the memory debugger.
+
+	* src/base/Jamfile: Updated.
+
+	* include/freetype/internal/internal.h (FT_INTERNAL_HASH_H,
+	FT_INTERNAL_OBJECT_H): New macros.
+
+	* include/freetype/internal/ftcore.h: New file to group all new
+	definitions related to exception handling and memory management.  It
+	is very likely that this file will disappear or be renamed in the
+	future.
+
+	* include/freetype/internal/ftobject.h, include/freetype/ftsysmem.h:
+	Adding comments to better explain the object sub-system as well as
+	the new memory manager interface.
+
+2002-04-30  Wenlin Institute (Tom Bishop)  <wenlin@wenlin.com>
+
+	* src/base/ftmac.c (p2c_str): Removed.

+	Various fixes to make the FT_CMaps support work correctly (more
+	tests are still needed).
+
+	* include/freetype/internal/ftobjs.h, src/sfnt/Jamfile,
+	src/sfnt/rules.mk, src/sfnt/sfnt.c, src/sfnt/sfobjs.c,
+	src/sfnt/ttload.c, src/sfnt/ttcmap0.c, src/sfnt/ttcmap0.h: Updated
+	the SFNT charmap support to use FT_CMaps.
+
+	* include/freetype/fterrdef.h: New file.
+	* include/freetype/fterrors.h: Include it.  It contains all error
+	codes.
+	* include/freetype/config/ftheader.h (FT_ERROR_DEFINITIONS_H): New
+	macro.
+
+	* include/freetype/internal/ftmemory.h, and a lot of other files:
+	Changed the names of memory macros.  Examples:
+
+	  MEM_Set   => FT_MEM_SET
+	  MEM_Copy  => FT_MEM_COPY
+	  MEM_Move  => FT_MEM_MOVE
+
+	  ALLOC     => FT_ALLOC
+	  FREE      => FT_FREE
+	  REALLOC   = >FT_REALLOC
+
+	FT_NEW was introduced to allocate a new object from a _typed_
+	pointer.
+
+	Note that ALLOC_ARRAY and REALLOC_ARRAY have been replaced by
+	FT_NEW_ARRAY and FT_RENEW_ARRAY which take _typed_ pointer
+	arguments.
+
+	This results in _lots_ of sources being changed, but makes the code
+	more generic and less error-prone.

+	  NEXT_UShortLE => FT_NEXT_USHORT_LE
+	  READ_Short    => FT_READ_SHORT

+
+	* src/psaux/t1cmap.h, src/psaux/t1cmap.c, src/type1/t1cmap.h,
+	src/type1/t1cmap.c: Updating and moving the Type 1 FT_CMap support
+	from `src/type1' to `src/psaux' since it is going to be shared by
+	the Type 1 and CID font drivers.

+
+	* src/base/ftdbgmem.c (ft_mem_table_destroy): Fixed a small bug that
+	caused the library to crash with Electric Fence when memory
+	debugging is used.
+
+	* Renaming stream macros.  Examples:
+

+	  FILE_Read    => FT_STREAM_READ
+	  ACCESS_Frame => FT_FRAME_ENTER

+
+	* include/freetype/internal/cfftypes.h, src/cff/*.c: Updating the
+	type definitions of the CFF font driver.
+
+	  CFF_Font  => CFF_FontRec

+
+	* src/type1/t1objs.c (T1_Face_Init), src/cff/cffobjs.c
+	(CFF_Face_Init), src/cid/cidobjs.c (CID_Face_Init): Removing the bug
+	that returned global BBox values in 16.16 fixed format (instead of
+	integer font units).
+
+	* src/cid/cidriver.c (cid_get_postscript_name): Fixed a bug that
+	caused the CID driver to return Postscript font names with a leading
+	slash (`/') as in `/MOEKai-Regular'.
+
+	* src/sfnt/ttload.c (TT_Load_Names), src/sfnt/sfobjs.c (Get_Name),
+	src/sfnt/sfdriver.c (get_sfnt_postscript_name): Fixed the loader so
+	that it accepts broken fonts like `foxjump.ttf', which made FreeType
+	crash when trying to load them.
+
+	Also improved the name table parser to be able to load
+	Windows-encoded entries before Macintosh or Unicode ones, since it
+	seems some fonts don't have reliable values here anyway.
+
+	* include/freetype/internal/psnames.h: Add typedef for
+	`PSNames_Service'.
+
+2002-03-05  Werner Lemberg  <wl@gnu.org>
+
+	* builds/unix/aclocal.m4, builds/unix/ltmain.sh: Update to libtool

+
+	* include/freetype/ftconfig.h: Changed `FT_LOCAL xxxx' to
+	`FT_LOCAL( xxxx )' everywhere in the source.  The same goes for
+	`FT_LOCAL_DEF xxxx' which is translated to `FT_LOCAL_DEF( xxxxx )'.
+
+	* include/freetype/freetype.h (FREETYPE_MINOR, FREETYPE_PATCH):
+	Changing version to 2.1.0 to indicate an unstable branch.

+
+	* include/freetype/t1tables.h: Renaming structure types.  This
+
+	  typedef  T1_Struct_
+	  {
+	  } T1_Struct;
+
+	becomes
+
+	  typedef  PS_StructRec_
+	  {
+	  } PS_StructRec, *PS_Struct;
+
+	  typedef PS_StructRec  T1_Struct;  /* backward compatibility */
+
+	Hence, we increase the coherency of the source code by effectively
+	using the `Rec' prefix for structure types.
+
+2002-02-27  David Turner  <david@freetype.org>
+
+	* src/sfnt/ttload.c (TT_Load_Names): Simplifying and securing the

+	experimental) code for Type 1 charmap processing.
+
+	* src/sfnt/ttcmap0.c: New file.  It contains a new, still
+	experimental SFNT charmap processing support.
+
+	* include/freetype/internal/ftobjs.h: Adding validation support as
+	well as internal charmap object definitions (FT_CMap != FT_CharMap).
+
+2002-02-24  David Turner  <david@freetype.org>

+
+	  FT_New_Stream( filename, stream ) =>
+	    FT_Stream_Open( stream, filename )
+
+	    (The function doesn't create the FT_Stream structure, it simply
+	    initializes it for reading.)
+
+	  FT_New_Memory_Stream( library, FT_Byte*  base, size, stream ) =>
+	    FT_Stream_Open_Memory( stream, const FT_Byte* base, size )
+
+	  FT_Done_Stream  => FT_Stream_Close
+	  FT_Stream_IO    => FT_Stream_IOFunc
+	  FT_Stream_Close => FT_Stream_CloseFunc
+
+	  ft_close_stream => ft_ansi_stream_close (in base/ftsystem.c only)
+	  ft_io_stream    => ft_ansi_stream_io    (in base/ftsystem.c only)
+
+	* src/base/ftutil.c: New file.  Contains all memory and list
+	management code (previously in `ftobjs.c' and `ftlist.c',
+	respectively).
+
+	* include/freetype/internal/ftobjs.h: Moving all code related to
+	glyph loaders to ...
+	* include/freetype/internal/ftgloadr.h: This new file.
+	`FT_GlyphLoader' is now a pointer to the structure

+	(ft_glyph_own_bitmap): Renamed to ...
+	(FT_GLYPH_OWN_BITMAP): This.
+	* src/base/ftobjs.c: Moving all code related to glyph loaders

+	Some stuff from ftdebug.h has been moved to ...
+
+	* include/freetype/internal/fttrace.h: New file, to define the trace

+
+	* include/freetype/internal/internal.h: Updated.
+
+	* src/base/ftobjs.c, src/base/ftstream.c: Updated.

+
+2006-05-03  David Turner  <david@freetype.org>
+
+	Allow compilation again with C++ compilers.
+
+	* include/freetype/internal/ftmemory.h (FT_ASSIGNP,
+	FT_ASSIGNP_INNER): New macros which do the actual assignment, and
+	which exist in two variants (for C and C++).
+	Update callers accordingly.
+
+2006-05-03  Werner Lemberg  <wl@gnu.org>
+
+	* include/freetype/config/ftoption.h (FT_STRICT_ALIASING): Removed.
+
+2006-05-02  Werner Lemberg  <wl@gnu.org>
+
+	* include/freetype/internal/ftmemory.h: s/new/newsz/ (for C++).
+	(FT_ALLOC): Remove redundant redefinition.
+
+	* builds/compiler/gcc-dev.mk (CFLAGS) [g++]: Don't use
+	`-Wstrict-prototypes'.
+
+	* src/base/ftstream.c (FT_Stream_EnterFrame): Add cast.
+
+	* include/freetype/config/ftconfig.h (FT_BASE_DEF) [__cplusplus]:
+	Remove `extern'.
+
+2006-05-02  David Turner  <david@freetype.org>
+
+	Update the memory management functions and macros to safely deal
+	with array size buffer overflows.  This corresponds to attempts to
+	allocate arrays that are too large.  For an example, consider the
+	following code:
+
+	  count = read_uint32_from_file(); array = malloc( sizeof ( Item ) *
+	  count ); for ( nn = 0; nn < count; nn++ )
+	    array[nn] = read_item_from_file();
+
+	If `count' is larger than `FT_UINT_MAX/sizeof(Item)', the
+	multiplication overflows, and the array allocated os smaller than
+	the data read from the file.  In this case, the heap will be
+	trashed, and this can be used as a denial-of-service attack, or make
+	the engine crash later.
+
+	The FT_ARRAY_NEW and FT_ARRAY_RENEW macros now ensure that the new
+	count is no larger than `FT_INT_MAX/item_size', otherwise a new
+	error code `FT_Err_Array_Too_Large' will be returned.
+
+	Note that the memory debugger now works again when FT_DEBUG_MEMORY
+	is defined.  FT_STRICT_ALIASING has disappeared; the corresponding
+	code is now the default.
+
+
+	* include/freetype/config/ftconfig.h (FT_BASE_DEF) [!__cplusplus]:
+	Don't use `extern'.
+
+	* include/freetype/fterrdef.h (FT_Err_Array_Too_Large): New error
+	code.
+
+	* include/freetype/internal/ftmemory.h (FT_DEBUG_INNER)
+	[FT_DEBUG_MEMORY]: New macro.
+	(ft_mem_realloc, ft_mem_qrealloc): Pass new object size count also.
+	(ft_mem_alloc_debug, ft_mem_qalloc_debug, ft_mem_realloc_debug,
+	ft_mem_qrealloc_debug, ft_mem_free_debug): Removed.
+	(FT_MEM_ALLOC, FT_MEM_REALLOC, FT_MEM_QALLOC, FT_MEM_QREALLOC,
+	FT_MEM_FREE): Redefine.
+	(FT_MEM_NEW_ARRAY, FT_MEM_RENEW_ARRAY, FT_MEM_QNEW_ARRAY,
+	FT_MEM_QRENEW_ARRAY): Redefine.
+	(FT_ALLOC_MULT, FT_REALLOC_MULT, FT_MEM_QALLOC_MULT,
+	FT_MEM_QREALLOC_MULT): New macros.  Update callers where
+	appropriate.
+	(FT_MEM_SET_ERROR): Slightly redefine.
+
+
+	* src/base/ftdbgmem.c (_ft_debug_file, _ft_debug_lineno)
+	[FT_DEBUG_MEMORY]: New global variables, replacing...
+	(FT_MemTableRec) [FT_DEBUG_MEMORY]: Remove `filename' and
+	`line_no'.  Update all callers.
+	(ft_mem_debug_alloc) [FT_DEBUG_MEMORY]: Avoid possible integer
+	overflow.
+	(ft_mem_alloc_debug, ft_mem_realloc_debug, ft_mem_qalloc_debug,
+	ft_mem_qrealloc_debug, ft_mem_free_debug): Removed.
+
+	* src/base/ftmac.c (read_lwfn): Catch integer overflow.
+	* src/base/ftrfork.c (raccess_guess_darwin_hfsplus): Ditto.
+	* src/base/ftutil.c: Remove special code for FT_STRICT_ALIASING.
+	(ft_mem_alloc, ft_mem_realloc, ft_mem_qrealloc): Rewrite.
+
+
+	* include/freetype/ftstream.h (FT_FRAME_ENTER, FT_FRAME_EXIT,
+	FT_FRAME_EXTRACT, FT_FRAME_RELEASE): Use FT_DEBUG_INNER to report the
+	place where the frames were entered, extracted, exited or released
+	in the memory debugger.
+
+	* src/base/ftstream.c (FT_Stream_ReleaseFrame) [FT_DEBUG_MEMORY]:
+	Call ft_mem_free.
+	(FT_Stream_EnterFrame) [FT_DEBUG_MEMORY]: Use ft_mem_qalloc.
+	(FT_Stream_ExitFrame) [FT_DEBUG_MEMORY]: Use ft_mem_free.
+
+2006-04-30  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	* src/base/ftobjs.c (Mac_Read_POST_Resource): Correct pfb_pos
+	initialization, remove extra cast to copy to pfb_lenpos.  This fixes
+	parsing of PFB fonts with MacOS resource fork (bug introduced
+	2003-09-11).  Patch provided by Huib-Jan Imbens <ft@imbens.nl>.

+	wrapper functions).
+
+	* src/base/ftsystem.c: Don't include stdio.h and stdlib.h.
+	* src/gzip/zutil.h [MSDOS && !(__TURBOC__ || __BORLANDC__)]: Don't

+2006-02-28  Chia-I Wu  <b90201047@ntu.edu.tw>
+
+	* src/base/ftutil.c (ft_mem_qalloc) [FT_STRICT_ALIASING]: Do not
+	return error when size == 0.
+
+2006-02-28  Chia-I Wu  <b90201047@ntu.edu.tw>
+
+	* src/base/ftobjs.c (FT_Done_Library): Remove modules in reverse
+	order so that type42 module is removed before truetype module.  This
+	avoids double free in some occasions.
+
+2006-02-28  David Turner  <david@freetype.org>
+
+	* Release candidate VER-2-2-0-RC4.

+2006-02-27  Werner Lemberg  <wl@gnu.org>
+
+	* include/freetype/cache/ftccache.h

+	it needs to be exported for rogue clients.
+
+	* src/pshinter/pshglob.c (psh_blues_set_zones_0): Prevent problems
+	with malformed fonts which have an odd number of blue values (these
+	are broken according to the specs).
+
+	* src/cff/cffload.c (cff_subfont_load), src/type1/t1load.c
+	(T1_Open_Face): Modify the loaders to force even-ness of

+
+2006-02-27  Chia-I Wu  <b90201047@ntu.edu.tw>
+

+2006-02-27  Chia-I Wu  <b90201047@ntu.edu.tw>
+
+	* src/base/ftobjs.c (GRID_FIT_METRICS): New macro.
+	(ft_glyphslot_grid_fit_metrics, FT_Load_Glyph) [GRID_FIT_METRICS]:
+	Re-enable glyph metrics grid-fitting.  It is now done in the base
+	layer.
+	(FT_Set_Char_Size, FT_Set_Pixel_Sizes): Make sure the width and
+	height are not too small or too large, just like we were doing in
+	2.1.10.
+
+	* src/autofit/afloader.c (af_loader_load_g): The vertical metrics
+	are not scaled.
+
+2006-02-26  Werner Lemberg  <wl@gnu.org>
+
+	* docs/release: Minor additions and clarifications.
+
+	* docs/CHANGES: Updated to reflect many fixes for backward
+	compatibility.  Still incomplete.
+
+2006-02-26  David Turner  <david@freetype.org>
+
+	* src/base/ftobjs.c (ft_recompute_scaled_metrics): Re-enable
+	conservative rounding of metrics to avoid breaking clients like
+	Pango (see https://bugzilla.gnome.org/show_bug.cgi?id=327852).
+
+2006-02-25  Werner Lemberg  <wl@gnu.org>
+
+	* devel/ftoption.h: Synchronize with
+	include/freetype/config/ftoption.h.
+
+	* src/cache/ftccache.c (ftc_node_destroy): Use FT_LOCAL_DEF (again).
+
+2006-02-25  David Turner  <david@freetype.org>
+
+	Fix compiler warnings as well as C++ compilation problems.
+	Add missing prototypes.
+
+	* src/autofit/afcjk.c, src/base/ftobjs.c, src/base/ftutil.c,
+	src/bdf/bdfdrivr.c, src/cff/cffcmap.c, src/cff/cffobjs.c,
+	src/psaux/afmparse.c,, src/psaux/t1cmap.c, src/smooth/ftgrays.c

+
+	* src/cache/ftcbasic.c: Fix `-Wmissing-prototypes' warnings with
+	gcc.
+
+	* builds/unix/ftsystem.c: Don't include FT_INTERNAL_OBJECTS_H but
+	FT_INTERNAL_STREAM_H.
+
+	* src/base/ftsystem.c: Include FT_INTERNAL_STREAM_H.
+
+	* include/freetype/config/ftheader.h (FT_PFR_H): New macro.

+
+	* src/base/ftoutln.c (FT_OUTLINE_GET_CONTOUR, ft_contour_has,

+
+2006-02-24  Chia-I Wu  <b90201047@ntu.edu.tw>
+
+	* include/freetype/ftbitmap.h (FT_Bitmap_Embolden): Update
+	documentation.
+
+	* include/freetype/ftsynth.h (FT_GlyphSlot_Own_Bitmap),

+	sure a glyph slot owns its bitmap.  It is also marked experimental
+	and due to change.
+	(FT_GlyphSlot_Embolden): Undo the last change.  It turns out that

+
+2006-02-24  David Turner  <david@freetype.org>
+
+	* Release candidate VER-2-2-0-RC3.
+	----------------------------------
+
+	* src/cache/ftcbasic.c: Correct compatibility hack bug.
+
+2006-02-24  Chia-I Wu  <b90201047@ntu.edu.tw>
+
+	* include/freetype/freetype.h (FT_Size_RequestRec): Change the type
+	of `width' and `height' to `FT_Long'.
+	(enum FT_Size_Request_Type), src/base/ftobjs.c (FT_Request_Metrics):
+	New request type `FT_SIZE_REQUEST_TYPE_SCALES' to specify the scales
+	directly.
+
+2006-02-23  David Turner  <david@freetype.org>
+
+	Two BDF patches from Debian libfreetype6 for 2.1.10.
+
+	* src/bdf/bdflib.c (_bdf_parse_glyphs): Fix a bug with zero-width
+	glyphs.
+	Fix a problem with large encodings.
+
+
+	Fix binary compatibility issues for gnustep-back (GNUstep backend
+	module) which still crashes under Sarge.
+
+	* src/cache/ftccmap.c (FTC_OldCMapType, FTC_OldCMapIdRec,
+	FTC_OldCMapDesc) [FT_CONFIG_OPTION_OLD_INTERNALS]: New data
+	structures and enumerations.
+	(FTC_CMapCache_Lookup) [FT_CONFIG_OPTION_OLD_INTERNALS]: New
+	compatibility code.
+
+	* src/cache/ftcbasic.c: Fix a silly bug that prevented our `hack' to
+	support rogue clients compiled against 2.1.7 to work correctly.
+	This probably explains the GNUstep crashes with the second release
+	candidate.
+
+2006-02-23  Chia-I Wu  <b90201047@ntu.edu.tw>
+
+	* include/freetype/ftoutln.h (enum FT_Orientation): New value
+	`FT_ORIENTATION_NONE'.
+
+	* src/base/ftoutln.c (FT_OUTLINE_GET_CONTOUR, ft_contour_has,
+	ft_contour_enclosed, ft_outline_get_orientation): Another version of
+	`FT_Outline_Get_Orientation'.  This version differs from the public
+	one in that each part (contour not enclosed in another contour) of the
+	outline is checked for orientation.
+	(FT_Outline_Embolden): Use `ft_outline_get_orientation'.
+
+	* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Render the outline and
+	use bitmap's embolden routine when the outline one failed.
+
+2006-02-22  Chia-I Wu  <b90201047@ntu.edu.tw>
+
+	* modules.cfg: Compile in ftotval.c and ftxf86.c by default for ABI
+	compatibility.
+
+	* src/sfnt/sfobjs.c (sfnt_done_face): Fix a memory leak.
+
+	* src/sfnt/ttsbit0.c (tt_sbit_decoder_load_bit_aligned,
+	tt_sbit_decoder_load_byte_aligned) [FT_OPTIMIZE_MEMORY]: Fix sbit
+	loading.  (Only tested with bit aligned sbit with x_pos == 0.)
+
+	* src/truetype/ttpload.c (tt_face_load_hdmx,
+	tt_face_get_device_metrics) [FT_OPTIMIZE_MEMORY]: `hdmx' is not
+	actually used.
+
+2006-02-21  David Turner  <david@freetype.org>
+
+	Add a new API named FT_Get_TrueType_Engine_Type to determine whether
+	we have a patented, unpatented, or unimplemented TrueType bytecode
+	interpreter.
+
+	The FT_Get_Module_Flags API was removed consequently.
+
+	* include/freetype/ftmodapi.h (FT_Module_Get_Flags): Removed.
+	Replaced with...
+	(FT_Get_TrueType_Engine_Type): This.
+	(FT_TrueTypeEngineType): New enumeration.
+
+	* include/freetype/internal/ftserv.h (FT_SERVICE_TRUETYPE_ENGINE_H):
+	New macro.
+
+	* src/base/ftobjs.c: Include FT_SERVICE_TRUETYPE_ENGINE_H.
+	(FT_Module_Get_Flags): Removed.  Replaced with...
+	(FT_Get_TrueType_Engine_Type): This.
+
+	* src/truetype/ttdriver.c: Include FT_SERVICE_TRUETYPE_ENGINE_H.
+	(tt_service_truetype_engine): New service structure.
+	(tt_services): Register it.
+
+	* include/freetype/internal/services/svtteng.h: New file.
+
+
+	* src/sfnt/sfobjs.c (sfnt_load_face): Fix silly bug that prevented
+	embedded bitmaps from being correctly listed and used.
+
+
+	* src/sfnt/ttmtx.c (tt_face_load_hmtx): Disable memory optimization
+	if FT_CONFIG_OPTION_OLD_INTERNALS is used.  The is necessary because
+	libXfont is directly accessing the HMTX data, unfortunately.
+	Fix some compiler warnings.
+	(tt_face_get_metrics): Ditto.
+
+
+	* src/pfr/pfrsbit.c (pfr_slot_load_bitmap): Fix handling of
+	character advances.
+
+2006-02-20  David Turner  <david@freetype.org>
+
+	Support binary compatibility with the X.Org server's Xfont library.
+	Note that this change unfortunately prevents memory optimizations
+	for the embedded bitmap loader.
+
+	* include/freetype/internal/sfnt.h (SFNT_Interface): Move
+	`set_sbit_strike' and `load_sbit_metrics' fields to the location of
+	version 2.1.8.
+
+	* src/sfnt/sfdriver.c (tt_face_set_sbit_strike_stub): Call
+	FT_Size_Request.
+	(sfnt_interface): Updated.
+
+	* src/sfnt/ttsbit.c [FT_CONFIG_OPTION_OLD_INTERNALS]: Don't load
+	ttsbit0.c.
+	(tt_load_sbit_metrics): Make `sbit_small_metrics_fields' static.
+
+	* src/sfnt/ttsbit.h: Updated.
+
+2006-02-17  David Turner  <david@freetype.org>
+
+	* builds/unix/unix-cc.in (LINK_LIBRARY): Don't filter out exported
+	functions anymore.  This ensures that all FT_BASE internal functions
+	are available for dynamic linking.
+
+	* include/freetype/ftcache.h (FTC_IMAGE_TYPE_COMPARE,
+	FTC_IMAGE_TYPE_HASH), src/cache/ftcbasic.c (FTC_OldFontRec,
+	FTC_OldImageDescRec, FTC_ImageCache_Lookup, FTC_Image_Cache_New,
+	FTC_OldImageDesc, FTC_OLD_IMAGE_FORMAT, ftc_old_image_xxx,
+	ftc_image_type_from_old_desc, FTC_Image_Cache_Lookup,
+	FTC_SBitCache_Lookup, FTC_SBit_Cache_New, FTC_SBit_Cache_Lookup)
+	[FT_CONFIG_OPTION_OLD_INTERNALS]: Try to revive old functions of the
+	cache sub-system.  We try to recognize old legacy signatures with a
+	gross hack (hope it works).
+
+2006-02-17  Werner Lemberg  <wl@gnu.org>
+
+	* devel/ftoption.h: Synchronize with
+	include/freetype/config/ftoption.h.
+
+2006-02-16  David Turner  <david@freetype.org>
+
+	Massive changes to the internals to respect the internal object
+	layouts and exported functions of FreeType 2.1.7.  Note that the
+	cache sub-system cannot be fully retrofitted, unfortunately.
+
+	* include/freetype/config/ftoption.h
+	(FT_CONFIG_OPTION_OLD_INTERNALS): New macro.
+
+	* include/freetype/ftcache.h, include/freetype/cache/ftccache.h,

+	src/type1/t1objs.c, src/type42/t42drivr.c, src/winfonts/winfnt.c:
+	Use FT_CONFIG_OPTION_OLD_INTERNALS to revive old functions and data
+	structures.
+
+	Move newly added structure elements to the end of the affected
+	structure and add stub fields (if FT_CONFIG_OPTION_OLD_INTERNALS is
+	defined) to assure binary compatibility with older FreeType
+	versions.
+	Use FT_CONFIG_OPTION_OLD_INTERNALS to add function stubs for old
+	functions:
+
+	  ft_stub_set_char_sizes
+	  ft_stub_set_pixel_sizes
+
+	Rename the following internal functions to provide the old function
+	names as stubs:
+
+	  FT_Alloc          -> ft_mem_alloc
+	  FT_QAlloc         -> ft_mem_qalloc
+	  FT_Realloc        -> ft_mem_realloc

+	  FT_Free_Debug     -> ft_mem_free_debug
+
+2006-02-15  Chia-I Wu  <b90201047@ntu.edu.tw>
+
+	* include/freetype/internal/ftobjs.h (FT_Face_InternalRec): Remove
+	unused `max_points' and `max_contours'.
+
+	* src/cid/cidobjs.c (cid_face_init), src/type1/t1objs.c
+	(T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Update.
+
+	* include/freetype/internal/tttypes.h (TT_FaceRec): Remove unused
+	`max_components'.
+
+	* src/truetype/ttinterp.h (TT_ExecContextRec): Remove unused
+	`loadSize' and `loadStack'.
+
+	* src/truetype/ttinterp.c (TT_Done_Context, TT_Load_Context),
+	src/sfnt/ttload.c (tt_face_load_maxp): Update.
+
+	* src/cff/cffobjs.h (cff_size_select), src/sfnt/sfdriver.c
+	(sfnt_interface), src/truetype/ttdriver.c (tt_size_request): Fix
+	compiler errors/warnings when TT_CONFIG_OPTION_EMBEDDED_BITMAPS is not
+	defined.
+
+	* src/sfnt/ttmtx.c (tt_face_load_hmtx, tt_face_get_metrics): Fix
+	possible segment faults for the non-FT_OPTIMIZE_MEMORY'ed versions.
+	(finally!)
+
+
+	For most OpenType tables, `tt_face_load_xxxx' simply loads the table
+	and `face->root' is set later in `sfnt_load_face'.  Here, we try to
+	make this work for _all_ tables.  Also improve tracing messages.
+
+	* src/sfnt/ttsbit.c, src/sfnt/ttsbit0.c, src/sfnt/ttload.c,
+	src/sfnt/ttmtx.c: all `tt_face_load_xxxx' should load the table and
+	then exit.  Error handling or setting face->root is done later in
+	`sfnt_load_face'.
+
+	* src/sfnt/sfobjs.c (sfnt_load_face): Work harder.
+	Mac bitmap-only fonts are not scalable.
+	Check that `face->header.Units_Per_EM' is not zero.
+	(LOAD_, LOADM_): Emit pretty trace messages.
+
+	* src/sfnt/ttsbit0.c (tt_face_load_strike_metrics): Read metrics
+	from `eblc'.
+
+	* src/sfnt/ttcmap.c (tt_face_build_cmaps), src/sfnt/ttpost.c
+	(load_format_20, load_format_25, tt_face_get_ps_name): Use
+	face->max_profile.numGlyphs, instead of face->root.num_glyphs.
+
+2006-02-14  Werner Lemberg  <wl@gnu.org>
+
+	* include/freetype/ftoutln.h (FT_Outline_Embolden): Mention in
+	documentation that negative strength values are possible.
+	Give an example call.
+
+	* include/freetype/freetype.h (FT_GlyphSlotRec): Improve
+	documentation of `outline' field.
+
+	* src/sfnt/sfobjs.c: Include FT_INTERNAL_DEBUG_H.
+	* src/sfnt/sfdriver.c: Include ttmtx.h.
+
+	* src/autofit/afcjk.c: Include aftypes.h and aflatin.h.
+
+2006-02-14  Chia-I Wu  <b90201047@ntu.edu.tw>
+
+	* src/sfnt/ttmtx.c (tt_face_get_metrics): Typo.
+
+2006-02-14  Chia-I Wu  <b90201047@ntu.edu.tw>
+
+	* src/sfnt/ttmtx.c (tt_face_load_hhea, tt_face_load_hmtx): Simply
+	return error if table is missing.
+	Check table length in non-FT_OPTIMIZE_MEMORY'ed `tt_face_load_hmtx'.
+
+	* src/sfnt/sfobjs.c (sfnt_load_face): Take care of missing metrics
+	tables.  The last change makes Mac bitmap-only font not load and
+	this fixes it.
+
+	* src/truetype/ttgload.c (load_truetype_glyph): Fix compilation
+	error when FT_CONFIG_OPTION_INCREMENTAL is defined.
+
+2006-02-13  Chia-I Wu  <b90201047@ntu.edu.tw>
+
+	Clean up the SFNT_Interface.  In this final pass, `load_hmtx' is
+	split from `load_hhea'.
+
+	* include/freetype/internal/sfnt.h, src/sfnt/sfdriver.c,
+	src/sfnt/ttmtx.c, src/sfnt/ttmtx.h: Split `hmtx' from `hhea'.
+
+	* src/sfnt/sfobjs.c (sfnt_load_face): Update.
+
+2006-02-13  Chia-I Wu  <b90201047@ntu.edu.tw>
+
+	* src/sfnt/ttmtx.h, src/sfnt/ttmtx.c: Why are there two copies of
+	code...
+
+2006-02-13  Chia-I Wu  <b90201047@ntu.edu.tw>
+
+	Clean up the SFNT_Interface.  In this pass, we want to treat the
+	font directory (offset table and table directory) as a normal table
+	like the others.  This also means that TTCs are no longer recognized
+	there but in `init_face'.
+
+	* include/freetype/internal/sfnt.h (SFNT_Interface),
+	src/sfnt/sfdriver.c: `load_sfnt_header' and `load_directory' are
+	combined and renamed to `load_font_dir'.
+
+	* src/sfnt/ttload.h, src/sfnt/ttload.c:
+	s/sfnt_dir_check/check_table_dir/.
+	`sfnt_init' is moved to sfobjs.c and renamed to `sfnt_open_font'.
+	`tt_face_load_sfnt_header' and `tt_face_load_directory' are combined
+	and renamed to `tt_face_load_font_dir'.
+
+	* src/sfnt/sfobjs.c (sfnt_init_face): Recognize TTC here.
+
+2006-02-13  Chia-I Wu  <b90201047@ntu.edu.tw>
+
+	Clean up the SFNT_Interface.  Table loading functions are now named
+	after the tables' tags; `hdmx' is TrueType-specific and thus the
+	code is moved to the truetype module; `get_metrics' is moved here
+	from the truetype module so that the code can be shared with the cff
+	module.
+
+	This pass involves no real changes.  That is, the code is moved
+	verbatim mostly.  The only exception is the return value of
+	`tt_face_get_metrics'.
+
+	* include/freetype/internal/sfnt.h, src/sfnt/rules.mk,
+	src/sfnt/sfdriver.c, src/sfnt/sfnt.c, src/sfnt/sfobjs.c,
+	src/sfnt/ttload.c, src/sfnt/ttload.h, src/sfnt/ttsbit.c,
+	src/sfnt/ttsbit.h, src/sfnt/ttsbit0.c: Clean up the SFNT_Interface.
+
+	* src/sfnt/ttmtx.c, src/sfnt/ttmtx.h: New files.  Metrics-related
+	tables' loading and parsing code is moved to here.
+	Move `tt_face_get_metrics' here from the truetype module.  The
+	return value is changed from `void' to `FT_Error'.
+
+	* include/freetype/internal/fttrace.h: New trace: ttmtx.
+
+	* src/truetype/ttpload.c, src/truetype/ttpload.h: `hdmx' loading and
+	parsing code is moved here.
+	New function `tt_face_load_prep' split from `tt_face_load_fpgm'.
+	`tt_face_load_fpgm' returns `FT_Err_Ok' if `fpgm' doesn't exist.
+
+	* src/cff/cffgload.c, src/cff/cffobjs.c: Update.
+
+	* src/truetype/ttgload.c, src/truetype/ttobjs.c: Update.
+
+2006-02-11  Chia-I Wu  <b90201047@ntu.edu.tw>
+
+	* src/autofit/afcjk.c (af_cjk_metrics_init): Fix a stupid bug...
+

+
+	Implement new, simplified module selection.  With GNU make it is now
+	sufficient to modify a single file, `modules.cfg', to control the
+	inclusion of modules and base extension files.
+
+	This change also fixes the creation of ftmodule.h; it now depends on
+	`modules.cfg' and thus is rebuilt only if necessary.
+
+	Finally, a version of `ftoption.h' in OBJ_DIR is preferred over the
+	default location.
+
+	* modules.cfg: New file.
+
+	* builds/freetype.mk: Don't include `modules.mk'.
+	Include all `rules.mk' files as specified in `modules.cfg'.

+	(make_module_list, clean_module_list): Replace targets
+	with...
+	(FTMODULE_H_INIT, FTMODULE_H_CREATE, FTMODULE_H_DONE): New
+	variables.  Reason for the change is that it is not possible to have
+	a phony prerequisite which is run only if the target file must be
+	rebuilt (phony prerequisites act like subroutines and are *always*
+	executed).  We only want to rebuild `ftmodule.h' if `module.cfg' is
+	changed.
+	Update all callers.
+	($FTMODULE_H)): Rule to create `ftmodule.h', depending on
+	`modules.cfg'.
+
+	* builds/toplevel.mk: Rewrite and simplify module handling.
+	(MODULES_CFG, FTMODULE_H): New variables.

+	defined.
+	(have_mk): Don't use `strip' function.
+	Test for unix-def.mk in OBJ_DIR, not BUILD_DIR (and invert the test
+	accordingly).
+
+	* builds/unix/install.mk (install, uninstall): Handle `ftmodule.h'.
+
+	* builds/os2/os2-dev.mk, builds/unix/unix-dev.mk,
+	builds/win32/w32-bccd.mk, builds/win32/w32-dev.mk: Don't define

+	Update snippet taken from autoconf's m4sh.m4 to current CVS version.
+	Be more verbose.
+
+	* include/freetype/config/ftmodule.h: Add comments -- this file is
+	no longer used if FreeType is built with GNU make.
+
+	* docs/CHANGES, docs/CUSTOMIZE, docs/INSTALL, docs/INSTALL.ANY,
+	docs/INSTALL.GNU, docs/INSTALL.UNX: Document new build mechanism.

+
+	* Jamfile, include/freetype/config/ftmodule.h: Remove `gxvalid'
+	and `otvalid' from the list of modules that are linked statically
+	to a given FreeType library.  Functionality has been moved to the

+
+	Note also that current Make-based build system still compiles the
+	modules though.
+
+	* include/freetype/config/ftoption.h (FT_STRICT_ALIASING): New macro
+	which controls the definitions of the memory management functions to
+	avoid warnings with recent versions of GCC.  This macro is only here
+	to be disabled, in case we detect problems with the new scheme.
+
+	NOTE: Disable macro to use the memory debugger -- this will be fixed
+	      later!
+
+	* include/freetype/internal/ftmemory.h, src/base/ftutil.c (FT_Alloc,

+
+	* include/freetype/internal/ftobjs.h (FT_Select_Metrics,
+	FT_Request_Metrics), src/base/ftobjs.c (FT_Select_Metrics,
+	FT_Request_Metrics): New base functions to set the font metrics.  They
+	were part of FT_Select_Size/FT_Request_Size and are made independent
+	functions so that metrics are not set again and again.
+
+	* src/base/ftobjs.c (FT_Select_Size, FT_Request_Size): Metrics are set
+	only when driver's size_select/size_request is NULL.  That is, drivers
+	should set the metrics themselves.
+	(FT_Match_Size): Round before matching.  This was what we did and it

+	s/index/strike_index/.
+	The scaled metrics are always preferred over strikes' metrics, even
+	when some strike is selected.  This is done because the strikes'

+	some fonts.
+
+	* src/cff/cffobjs.c (cff_size_request), src/truetype/ttdriver.c
+	(tt_size_request): Set the font metrics.

+	(PS_Conv_ASCIIHexDecode, PS_Conv_EexecDecode): Speed up a little.
+
+	* src/sfnt/ttsbit.c (tt_face_load_sbit_strikes,
+	tt_face_load_strike_metrics), src/sfnt/ttsbit0.c

+
+2006-01-20  David Turner  <david@freetype.org>
+

+
+	Change the implementation of the LIGHT hinting mode to completely
+	disable horizontal hinting.  This is an experimental effort to
+	integrate David Chester's latest patch without affecting the other
+	hinting modes as well.
+
+	Note that this doesn't force auto-hinting for all fonts, however.
+
+	* src/autofit/afhints.c (af_glyph_hints_reload): Don't set

+	(af_glyph_hints_rescale): Here.
+
+	* src/autofit/aflatin.c (af_latin_hints_init): Disable horizontal

+
+
+	* Jamfile: Small fix to ensure that ftexport.sym is placed into the
+	same location as other generated objects (i.e., within the `objs'
+	directory of the current directory).
+
+
+	Add support for an embedded `BDF ' table within SFNT-based bitmap
+	font files.  This is used to store atoms & properties from the
+	original BDF fonts that were used to generate the font file.
+
+	The feature is controlled by TT_CONFIG_OPTION_BDF within
+	`ftoption.h' and is used to implement FT_Get_BDF_Property for these
+	font files.
+
+	At the moment, this is still experimental, the BDF table format
+	isn't cast into stone yet.

+	Take care of overlapping segments.
+	(tt_cmap4_validate): Make sure the subtable is large enough.
+	Do not check glyph_ids because some fonts set the length wrongly.
+	Also, if all segments have offset 0, glyph_ids is always invalid.
+	It does not cause any problem so far only because the check misses
+	equality.
+	Distinguish between unsorted and overlapping segments.
+	(tt_cmap4_char_map_linear, tt_cmap4_char_map_binary): New functions
+	to do `charcode => glyph index' by linear/binary search.
+	(tt_cmap4_char_index, tt_cmap4_char_next): Use

+	* src/sfnt/ttload.c (sfnt_dir_check): Modified to allow a
+	font to have no `head' table if tables `SING' and `META' are
+	present; this is to support `SING Glyphlet'.
+
+	`SING Glyphlet' is an extension to OpenType developed by Adobe
+	primarily to facilitate adding supplemental glyphs to an OpenType
+	font (with emphasis on, but not necessarily limited to, gaiji to a
+	CJK font).  A SING Glyphlet Font is an OpenType font that contains
+	the outline(s), either in a `glyf' or `CFF' table, for a glyph;
+	`cmap', `BASE', and `GSUB' tables are present with the same format
+	and functionality as a regular OpenType font; there are no `name',
+	`head', `OS/2', and `post' tables; there are two new tables, `SING'
+	which contains details about the glyphlet, and `META' which contains
+	metadata.
+
+	Further information on the SING Glyphlet format can be found at:
+
+	  https://www.adobe.com/content/dam/acom/en/devnet/font/pdfs/5148.SING_Tutorial.pdf
+
+	* include/freetype/tttags.h (TTAG_SING, TTAG_META): New macros for
+	the OpenType tables `SING' and `META'.  These two tables are used in
+	SING Glyphlet Format fonts.

+
+	* src/truetype/ttgload.c (TT_Load_Glyph): Only translate outline
+	to (0,0) if bit 1 of the `head' table isn't set.  This improves
+	rendering of buggy fonts.
+
+2005-08-20  Chia I Wu  <b90201047@ntu.edu.tw>
+
+	* src/truetype/ttdriver.c (Load_Glyph): Don't check the validity of
+	ttmetrics here.  TrueType fonts with only sbits always have

+	(TT_LOADER_SET_PP): New macro to calculate and set the four phantom
+	points.
+	(load_truetype_glyph): Never set exec->glyphSize to 0.  This closes
+	Savannah bug #13107.
+	Forget glyph frame before calling TT_Process_Simple_Glyph.
+	Use TT_LOADER_SET_PP.
+	Scale all four phantom points.
+	Split off some functionality to ...
+	(TT_Process_Composite_Component, TT_Process_Composite_Glyph): These

+	which won't be fixed in the very near future).
+
+	* Jamfile (FT2_COMPONENTS): Include otvalid (again).

+
+2010-02-10  Ken Sharp  <ken.sharp@artifex.com>
+
+	Really fix Savannah bug #28678 (part 2).
+
+	Since we consider `sbw' for the horizontal direction only, we still have
+	to synthesize vertical metrics if the user wants to use the vertical
+	writing direction.
+
+	* src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c
+	(cid_slot_load_glyph), src/type1/t1gload.c (T1_Load_Glyph):
+	Synthesize vertical metrics (only) if FT_LOAD_VERTICAL_LAYOUT is
+	set.
+
+2010-02-10  Ken Sharp  <ken.sharp@artifex.com>
+
+	Really fix Savannah bug #28678 (part 1).
+
+	After long discussion, we now consider the character width vector
+	(wx,wy) returned by the `sbw' Type 1 operator as being part of *one*
+	direction only.  For example, if you are using the horizontal
+	writing direction, you get the horizontal and vertical components of
+	the advance width for this direction.  Note that OpenType and CFF fonts
+	don't have such a vertical component; instead, the GPOS table can be
+	used to generate two-dimensional advance widths (but this isn't
+	handled by FreeType).
+
+	* include/freetype/ftincrem.h (FT_Incremental_MetricsRec): Add
+	`advance_v' field to hold the vertical component of the advance
+	value.
+
+	* src/truetype/ttgload.c (tt_get_metrics), src/cff/cffgload.c
+	(cff_slot_load), src/type1/t1gload.c
+	(T1_Parse_Glyph_And_Get_Char_String), src/cid/cidgload.c
+	(cid_load_glyph): Use it.
+
+2010-02-08  Werner Lemberg  <wl@gnu.org>
+
+	* devel/ftoption.h [FT_CONFIG_OPTION_PIC]: Define.
+
+2010-02-04  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	Prevent NULL pointer dereference passed to FT_Module_Requester.
+
+	* src/sfnt/sfdriver.c (sfnt_get_interface): Don't use `module'.
+	* src/psnames/psmodule.c (psnames_get_interface): Ditto.
+
+	* src/cff/cffdrivr.c (cff_get_interface): Check NULL `driver'.
+	* src/truetype/ttdriver.c (tt_get_interface): Ditto.
+
+2010-01-29  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	Fix memory leaks in previous patch.
+
+	* src/sfnt/sfobjs.c (sfnt_load_face): Don't overwrite the strings
+	allocated for face->root.family_name and style_name.
+
+2010-01-29  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	New parameters for FT_Open_Face() to ignore preferred family names.
+
+	Preferred family names should be used for legacy systems that

+	Andreas Heinrich.
+	https://lists.gnu.org/archive/html/freetype/2010-01/msg00001.html

+	ignore preferred family and subfamily names if requested.
+
+2010-01-27  Ken Sharp  <ken.sharp@artifex.com>
+
+	Fix Savannah bug #28678.
+
+	* src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c
+	(cid_load_glyph): Handle vertical metrics correctly.
+
+	* src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Handle
+	vertical metrics correctly.
+	(T1_Load_Glyph): Don't synthesize vertical metrics.
+
+2010-01-14  Werner Lemberg  <wl@gnu.org>
+
+	Make FT_Set_Transform work if no renderer is available.
+
+	* src/base/ftobjs.c (FT_Load_Glyph): Apply `standard' transformation
+	if no renderer is compiled into the library.
+
+2010-01-14  Werner Lemberg  <wl@gnu.org>
+
+	Fix compilation warning.
+
+	* src/base/ftbase.h: s/LOCAL_DEF/LOCAL/.
+	* src/base/ftobjs.c: Include ftbase.h conditionally.
+
+2010-01-11  Kwang Yul Seo  <skyul@company100.net>
+
+	Provide inline assembly code for RVCT compiler.
+	This is Savannah patch #7059.
+
+	* include/freetype/config/ftconfig.h (FT_MULFIX_ASSEMBLER,
+	FT_MulFix_arm) [__CC_ARM || __ARM_CC]: Define.
+
+2010-01-08  Ken Sharp  <ken.sharp@artifex.com>
+
+	Fix Savannah bug #28521.
+
+	Issue #28226 involved a work-around for a font which used the
+	`setcurrentpoint' operator in an invalid way; this operator is only
+	supposed to be used with the result of OtherSubrs, and the font used
+	it directly.  The supplied patch removed the block of code which
+	checked this usage entirely.
+
+	This turns out to be a Bad Thing.  If `setcurrentpoint' is being
+	used correctly it should reset the flex flag in the decoder.  If we
+	don't do this then the flag never gets reset and we omit any further
+	contours from the glyph (at least until we close the path or
+	similar).
+
+	* src/psaux/t1decode.c (t1_decoder_parse_charstrings)
+	<op_setcurrentpoint>: Handle `flex_state' correctly.
+
+2010-01-05  Werner Lemberg  <wl@gnu.org>
+
+	Apply reports from clang static analyzer.
+
+	* src/lzw/ftlzw.c (ft_lzw_file_init), src/base/ftstroke.c
+	(FT_Stroker_ParseOutline), src/base/ftsynth.c
+	(FT_GlyphSlot_Embolden): Remove dead code.
+
+	* src/base/ftpatent.c (_tt_check_patents_in_table): Initialize
+	`offset_i' and `length_i'.
+
+2010-01-05  Ralph Giles  <giles@ghostscript.com>
+
+	Enable the incremental font interface by default.
+
+	Ghostscript requires the incremental font interface for handling
+	some Postscript documents.  It is moving to using FreeType as its
+	primary renderer; supporting this in the default build makes it
+	Ghostscript to be linked against the system FreeType when one is
+	available.
+
+	* include/freetype/config/ftoption.h (FT_CONFIG_OPTION_INCREMENTAL):
+	Uncomment.
+
+2010-01-05  Werner Lemberg  <wl@gnu.org>
+
+	Fix Savannah bug #28395.
+
+	* src/truetype/ttdriver.c (Load_Glyph), src/type1/t1gload.c
+	(T1_Load_Glyph): Don't check `num_glyphs' if incremental interface
+	is used.
+
+2010-01-05  Ken Sharp  <ken.sharp@artifex.com>
+
+	Make Type 1 `seac' operator work with incremental interface.
+	This fixes Savannah bug #28480.
+
+	* src/psaux/t1decode.c (t1operator_seac): Don't check `glyph_names'
+	if incremental interface is used.
+
+2010-01-04  Ken Sharp  <ken.sharp@artifex.com>
+
+	Make incremental interface work with TrueType fonts.
+	This fixes Savannah bug #28478.
+
+	* src/truetype/ttgload.c (load_truetype_glyph): Don't check
+	`glyf_offset' if incremental interface is used.
+
+2009-12-31  Lars Abrahamsson  <wonko@opera.com>
+
+	Make compilation with FT_CONFIG_OPTION_PIC work again.
+
+	* src/base/ftglyph.c (FT_Glyph_To_Bitmap) [FT_CONFIG_OPTION_PIC]:
+	Declare `library' for FT_BITMAP_GLYPH_CLASS_GET.
+
+	* src/base/ftinit.c (ft_destroy_default_module_classes,
+	ft_create_default_module_classes): Use proper casts (needed for C++
+	compilation).
+
+	* src/sfnt/ttcmap.c (tt_cmap13_class_rec): Use FT_DEFINE_TT_CMAP.
+
+2009-12-22  Marc Kleine-Budde  <mkl@pengutronix.de>
+
+	Make freetype-config aware of $SYSROOT.
+	This is Savannah patch #7040.
+
+	* builds/unix/freetype-config.in: Decorate with ${SYSROOT} where
+	appropriate.
+
+2009-12-20  Werner Lemberg  <wl@gnu.org>
+
+	Fix compiler warning.
+	Reported by Sean.
+
+	* src/base/ftdbgmem.c [!FT_DEBUG_MEMORY]: ANSI C doesn't like empty
+	source files; however, some compilers warn about an unused variable
+	declaration.  This is now replaced with a typedef.
+
+2009-12-18  Werner Lemberg  <wl@gnu.org>
+
+	Fix Savannah bug #28320.
+
+	There exist corrupt, subsetted fonts (embedded in PDF files) which
+	contain a private dict that ends with an unterminated floating point
+	number (no operator following).  We now ignore this error (as
+	acrobat does).
+
+	* src/cff/cffparse.c (cff_parser_run): Don't emit a syntax error for
+	unterminated floating point numbers.
+
+2009-12-16  Werner Lemberg  <wl@gnu.org>
+
+	Really fix compiler warnings.

+
+	Ignore invalid `setcurrentpoint' operations in Type 1 fonts.
+	This fixes Savannah bug #28226.
+
+	At least two wild PostScript files of unknown provenance contain
+	Type 1 fonts, apparently converted from TrueType fonts in earlier
+	PDF versions of the files, which use the `setcurrentpoint' operator
+	inappropriately.
+
+	FreeType currently throws an error in this case, but Ghostscript and
+	Adobe Distiller both accept the fonts and ignore the problem.  This
+	commit #ifdefs out the check so PostScript interpreters using
+	FreeType can render these files.
+
+	The specification says `setcurrentpoint' should only be used to set
+	the point after a `Subr' call, but these fonts use it to set the
+	initial point to (0,0).  Unnecessarily so, as they correctly use an
+	`hsbw' operation which implicitly sets the initial point.

+	[BDF] Modify hash API to take size_t value instead of void *.

+
+	Improve vertical metrics calculation (Savannah bug #27364).
+
+	The calculation of `vertBearingX' is not defined in the OTF font
+	spec so FreeType does a `best effort' attempt.  However, this value
+	is defined in the PDF and PostScript specs, and that algorithm is
+	better than the one FreeType currently uses:
+
+	  FreeType: Use the middle of the bounding box as the X coordinate
+	            of the vertical origin.
+
+	  Adobe PDF spec: Use the middle of the horizontal advance vector as
+	                  the X coordinate of the vertical origin.
+
+	FreeType's algorithm goes wrong if you have a really small glyph
+	(like the full-width, circle-like dot at the end of the sentence, as
+	used in CJK scripts) with large bearings.  With the FreeType
+	algorithm this dot gets centered on the baseline; with the PDF
+	algorithm it gets the correct location (in the top right).  Note
+	that this is a serious issue, it's like printing the dot at the end
+	of a Roman sentence at the center of the textline instead of on the
+	baseline like it should. So i believe the PDF spec's algorithm
+	should be used in FreeType as well.
+
+	The `vertBearingY' value for such small glyphs is also very strange
+	if no `vmtx' information is present, since the height of the bbox is
+	not representable for the height of the glyph visually (the
+	whitespace up to the baseline is part of the glyph).  The fix also
+	includes some code for a better estimate of `vertBearingY'.
+
+	* src/base/ftobjs.c (ft_synthesize_vertical_metrics): `vertBearingX'
+	is now calculated as described by the Adobe PDF Spec.  Estimate for
+	`vertBearingY' now works better for small glyphs completely above or
+	below the baseline into account.
+
+	* src/cff/cffgload.c (cff_slot_load): `vertBearingX' is now
+	calculated as described by the Adobe PDF Spec.  Vertical metrics
+	information was always ignored when FT_CONFIG_OPTION_OLD_INTERNALS
+	was not defined.
+
+	* src/truetype/ttgload.c (compute_glyph_metrics): `vertBearingX' is
+	now calculated as described by the Adobe PDF Spec.

+
+	Previously, only integers have been used which can lead to serious

+	applying scaling.  This should be fixed; at the same time a new load
+	flag should be introduced, to be used in combination with

+	16.16 format.  Similarly, the incremental interface should be

+
+	Fix B/W rasterization of subglyphs with different drop-out modes.
+
+	Normally, the SCANMODE instruction (if present) to set the drop-out
+	mode in a TrueType font is located in the `prep' table only and thus
+	valid for all glyphs.  However, there are fonts like `pala.ttf'
+	which additionally contain this instruction in the hinting code of
+	some glyphs (but not all).  As a result it can happen that a
+	composite glyph needs multiple drop-out modes for its subglyphs
+	since the rendering state gets reset for each subglyph.
+
+	FreeType collects the hinted outlines from all subglyphs, then it
+	sends the data to the rasterizer.  It also sends the drop-out mode
+	-- after hinting has been applied -- and here is the error: It sends
+	the drop-out mode of the last subglyph only; drop-out modes of all
+	other subglyphs are lost.
+
+	This patch fixes the problem; it adds a second, alternative
+	mechanism to pass the drop-out mode: For each contour, the
+	rasterizer now checks the first `tags' array element.  If bit 2 is
+	set, bits 5-7 contain the contour's drop-out mode, overriding the
+	global drop-out mode.
+
+	* include/freetype/ftimage.h (FT_CURVE_TAG_HAS_SCANMODE): New macro.
+
+	* src/truetype/ttgload.c (TT_Hint_Glyph): Store drop-out mode in

+	(Decompose_Curve): Check `tags[0]' and set `dropOutControl' if
+	necessary.

+	mode.
+
+2009-06-16  Werner Lemberg  <wl@gnu.org>
+
+	Improve scan conversion rules 4 and 6.
+
+	Two new constraints are introduced to better identify a `stub' -- a
+	concept which is only vaguely described in the OpenType
+	specification.  The old code was too rigorous and suppressed more
+	pixel than it should.
+
+	  . The intersection of the two profiles with the scanline is less
+	    than a half pixel.  Code related to this was already present in
+	    the sources but has been commented out.
+
+	  . The endpoint of the original contour forming a profile has a
+	    distance (`overshoot') less than half a pixel to the scanline.
+
+	Note that the two additional conditions fix almost all differences
+	to the Windows rasterizer, but some problematic cases remain.
+
+	* src/raster/ftraster.c (Overshoot_Top, Overshoot_Bottom): New
+	macros for the `flags' field in the `TProfile' structure.

+
+	* src/sfnt/rules.mk (SFNT_DRV_H): Add ttsbit0.c.
+
+2009-03-09  Alexey Kryukov  <anagnost@yandex.ru>
+
+	Fix handling of EBDT formats 8 and 9 (part 2).
+
+	This patch fixes the following problems in ttsbit0.c:
+
+	. Bitmaps for compound glyphs were never allocated.
+
+	. `SBitDecoder' refused to load metrics if some other metrics have
+	  already been loaded.  This condition certainly makes no sense for
+	  recursive calls, so I've just disabled it.  Another possibility
+	  would be resetting `decoder->metrics_loaded' to false before
+	  loading each composite component.  However, we must restore the
+	  original metrics after finishing the recursion; otherwise we can
+	  get a misaligned glyph.
+
+	. `tt_sbit_decoder_load_bit_aligned' incorrectly handled `x_pos',
+	  causing some glyph components to be shifted too far to the right
+	  (especially noticeable for small sizes).
+
+	Note that support for grayscale bitmaps (not necessarily compound) is
+	completely broken in ttsbit0.c.
+
+	* src/sfnt/tt_sbit_decoder_load_metrics: Always load metrics.
+	(tt_sbit_decoder_load_bit_aligned): Handle `x_pos' correctly in case
+	of `h == height'.
+	(tt_sbit_decoder_load_compound): Reset metrics after loading
+	components.
+	Allocate bitmap.

+
+	FT_USE_MODULE declares things as:
+
+	  extern const FT_Module_Class
+
+	(or similar for C++).  However, the actual types of the variables
+	being declared are often different, e.g., FT_Driver_ClassRec or
+	FT_Renderer_Class.  (Some are, indeed, FT_Module_Class.)
+
+	This works with most C compilers (since those structs begin with an
+	FT_Module_Class struct), but technically it's undefined behavior.
+
+	To quote the ISO/IEC 9899:TC2 final committee draft, section 6.2.7
+	paragraph 2:
+
+	  All declarations that refer to the same object or function shall
+	  have compatible type; otherwise, the behavior is undefined.
+
+	(And they are not compatible types.)
+
+	Most C compilers don't reject (or even detect!) code which has this
+	issue, but the GCC LTO development branch compiler does.  (It
+	outputs the types of the objects while generating .o files, along
+	with a bunch of other information, then compares them when doing the
+	final link-time code generation pass.)

+
+	Generalize the concept of `tricky' fonts by introducing
+	FT_FACE_FLAG_TRICKY to indicate that the font format's hinting
+	engine is necessary for correct rendering.
+
+	At the same time, slightly modify the behaviour of tricky fonts:
+	FT_LOAD_NO_HINTING is now ignored.  To really force raw loading
+	of tricky fonts (without hinting), both FT_LOAD_NO_HINTING and
+	FT_LOAD_NO_AUTOHINT must be used.
+
+	Finally, tricky TrueType fonts always use the bytecode interpreter
+	even if the patented code is used.

+	* docs/CHANGES: Add note about the current status of sfnt-wrapped
+	Type1 and sfnt-wrapped CID-keyed font support.
+
+2008-09-18  Werner Lemberg  <wl@gnu.org>
+
+	* src/base/ftsystem.c (FT_Done_Memory): Use ft_sfree directly for
+	orthogonality (ft_free and ft_sfree could belong to different memory
+	pools).  This fixes Savannah bug #24297.
+
+2008-09-18  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	* src/cff/cffobjs.c (cff_face_init): Use TTAG_OTTO defined
+	in tttags.h instead of numerical value 0x4F54544FL.
+
+2008-09-16  Werner Lemberg  <wl@gnu.org>
+
+	* src/cff/cffgload.h, src/cff/cffgload.c
+	(cff_decoder_set_width_only): Eliminate function call.
+
+2008-09-15  George Williams  <gww@silcom.com>
+
+	Fix Savannah bug #24179, reported by Bram Tassyns.
+
+	* src/type1/t1load.c (mm_axis_unmap, T1_Get_MM_Var): Fix computation
+	of default values.
+
+2008-09-15  Werner Lemberg  <wl@gnu.org>
+
+	* src/tools/glnames.py (main): Surround `ft_get_adobe_glyph_index'
+	and `ft_adobe_glyph_list' with FT_CONFIG_OPTION_ADOBE_GLYPH_LIST to
+	prevent unconditional definition.  This fixes Savannah bug #24241.
+
+	* src/psnames/pstables.h: Regenerated.
+
+2008-09-13  Werner Lemberg  <wl@gnu.org>
+
+	* autogen.sh, builds/unix/configure.raw,
+	include/freetype/config/ftconfig.h, builds/unix/ftconfig.in: Minor
+	beautifying.
+
+	* include/freetype/ftadvanc.h, include/freetype/ftgasp.h,
+	include/freetype/ftlcdfil.h: Protect against FreeType 1.
+	Some other minor fixes.
+
+	* devel/ftoption.h: Synchronize with
+	include/freetype/config/ftoption.h.
+
+2008-09-11  Werner Lemberg  <wl@gnu.org>
+
+	* src/base/ftbase.c: Include ftadvanc.c.
+
+2008-09-11  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	* builds/unix/ftconfig.in: Duplicate the cpp computation of
+	FT_SIZEOF_{INT|LONG} from include/freetype/config/ftconfig.h.
+	(FT_USE_AUTOCONF_SIZEOF_TYPES): New macro.  If defined, the cpp
+	computation is disabled and the statically configured sizes are
+	used.  This fixes Savannah bug #21250.
+
+	* builds/unix/configure.raw: Add the checks to compare the cpp
+	computation results of the bit length of int and long versus the
+	sizes detected by running `configure'.  If the results are
+	different, FT_USE_AUTOCONF_SIZEOF_TYPES is defined to prioritize the
+	results.
+	New option --{enable|disable}-biarch-config is added to define or
+	undefine FT_USE_AUTOCONF_SIZEOF_TYPES manually.
+
+2008-09-05  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	* builds/unix/configure.raw: Clear FT2_EXTRA_LIBS when Carbon or
+	ApplicationServices framework is missing.  Although this value is not
+	used in building of FreeType2, it is written in `freetype2.pc' and
+	`freetype-config'.
+
+2008-09-01  David Turner  <david@freetype.org>
+
+	* src/cache/ftccmap.c (FTC_CMapCache_Lookup): Accept a negative cmap
+	index to mean `use default cached FT_Face's charmap'.  This fixes
+	Savannah bug #22625.
+	* include/freetype/ftcache.h: Document it.
+
+
+	Make FT_MulFix an inlined function.  This is done to speed up
+	FreeType a little (on x86 3% when loading+hinting, 10% when
+	rendering, ARM savings are more important though).  Disable this by
+	undefining FT_CONFIG_OPTION_INLINE_MULFIX.
+
+	Use of assembler code can now be controlled with
+	FT_CONFIG_OPTION_NO_ASSEMBLER.
+
+	* include/freetype/config/ftconfig.h, builds/unix/ftconfig.in
+	[!FT_CONFIG_OPTION_NO_ASSEMBLER] (FT_MulFix_arm): New assembler
+	implementation.
+	[!FT_CONFIG_OPTION_NO_ASSEMBLER] (FT_MulFix_i386): Assembler
+	implementation taken from `ftcalc.c'.
+	[!FT_CONFIG_OPTION_NO_ASSEMBLER] (FT_MULFIX_ASSEMBLER): New macro
+	which is defined to the platform-specific assembler implementation
+	of FT_MulFix.
+	[FT_CONFIG_OPTION_INLINE_MULFIX && FT_MULFIX_ASSEMBLER]
+	(FT_MULFIX_INLINED): New macro.
+
+	* include/freetype/config/ftoption.h (FT_CONFIG_OPTION_NO_ASSEMBLER,
+	FT_CONFIG_OPTION_INLINE_MULFIX): New macros.
+
+	* include/freetype/freetype.h: Updated to handle FT_MULFIX_INLINED.
+
+	* src/base/ftcalc.c: Updated to use FT_MULFIX_ASSEMBLER and
+	FT_MULFIX_INLINED.
+
+
+	Add a new header named FT_ADVANCES_H declaring some new APIs to
+	extract the advances of one or more glyphs without necessarily
+	loading their outlines.  Also provide `fast loaders' for the
+	TrueType, Type1, and CFF font drivers (more to come later).
+
+	* src/base/ftadvanc.c, include/freetype/ftadvanc.h: New files.
+
+	* include/freetype/config/ftheader.h (FT_ADVANCES_H): New macro.
+	* include/freetype/freetype.h (FT_LOAD_ADVANCE_ONLY): New macro.
+
+	* include/freetype/internal/ftdriver.h (FT_Face_GetAdvancesFunc):
+	`flags' and `advances' are now of type `FT_UInt' and `FT_Fixed',
+	respectively.
+
+	* src/base/Jamfile (_sources), src/base/rules.mk (BASE_SRC): Add
+	ftadvanc.c.
+
+	* src/cff/cffdrivr.c (cff_get_advances): New function.
+	(cff_driver_class): Register it.
+
+	* src/cff/cffgload.c (cff_decoder_set_width_only): New function.
+	(cff_decoder_parse_charstrings): Handle `width_only'.
+	(cff_slot_load): Handle FT_LOAD_ADVANCE_ONLY.
+
+	* src/cff/cffgload.h (cff_decoder): New element `width_only'.
+	(cff_decoder_set_width_only): New declaration.
+
+	* src/truetype/ttdriver.c (tt_get_advances): New function.
+	(tt_driver_class): Register it.
+
+	* src/truetype/ttgload.c (Get_HMetrics, Get_VMetrics): Renamed to...
+	(TT_Get_HMetrics, TT_Get_VMetrics): This.
+	Update callers.
+	* src/truetype/ttgload.h: Declare them.
+
+	* src/type1/t1gload.h, src/type1/t1gload.c (T1_Get_Advances): New
+	function.
+	* src/type1/t1driver.c (t1_driver_class): Register T1_Get_Advances.
+
+
+	Add checks for minimum version of the `autotools' stuff.
+
+	* autogen.sh: Implement it.
+	(get_major_version, get_minor_version, get_patch_version,
+	compare_to_minimum_version, check_tool_version): New auxiliary
+	functions.
+
+	* README.CVS: Document it.
+
+2008-08-29  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	* src/sfnt/sfobjs.c (sfnt_open_font): Use TTAG_OTTO defined in
+	tttags.h instead of FT_MAKE_TAG( 'O', 'T', 'T', 'O' ).
+
+2008-08-28  Werner Lemberg  <wl@gnu.org>
+
+	* src/type1/t1load.c (parse_encoding): Protect against infinite
+	loop.  This fixes Savannah bug #24150 (where a patch has been posted
+	too).
+
+2008-08-23  Werner Lemberg  <wl@gnu.org>
+
+	* src/type/t1afm.c (compare_kern_pairs), src/psaux/afmparse.c
+	(afm_compare_kern_pairs): Fix comparison.  This fixes Savannah bug
+	#24119.
+
+2008-08-19  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	* src/base/ftobjs.c (FT_Stream_New): Initialize *astream always,
+	even if passed library or arguments are invalid.  This fixes a bug
+	that an uninitialized stream is freed when an invalid library handle
+	is passed.  Originally proposed by Mike Fabian, 2008/08/18 on
+	freetype-devel.
+	(FT_Open_Face): Ditto (stream).
+	(load_face_in_embedded_rfork): Ditto (stream2).
+
+2008-08-18  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	* src/base/ftmac.c: Add a fallback to guess the availability of the
+	`ResourceIndex' type.  It is used when built without configure
+	(e.g., a build with Jam).
+	* builds/mac/ftmac.c: Ditto.
+	* builds/unix/configure.raw: Set HAVE_TYPE_RESOURCE_INDEX to 1 or 0
+	explicitly, even if `ResourceIndex' is unavailable.
+
+2008-08-18  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	* builds/unix/configure.raw: In checking of Mac OS X features,
+	all-in-one header file `Carbon.h' is replaced by the minimum
+	header file `CoreServices.h', similar to current src/base/ftmac.c.
+
+2008-08-18  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	* src/sfnt/ttcmap.c (tt_cmap2_validate): Skip the validation of
+	sub-header when its code_count is 0.  Many Japanese Dynalab fonts
+	include such an empty sub-header (code_count == 0, first_code == 0
+	delta == 0, but offset != 0) as the second sub-header in SJIS cmap.
+
+2008-08-04  Werner Lemberg  <wl@gnu.org>
+
+	* src/type1/t1tokens.h: Handle `ForceBold' keyword.  This fixes
+	Savannah bug #23995.
+
+	* src/cid/cidload.c (parse_expansion_factor): New callback function.
+	(cid_field_records): Use it for `ExpansionFactor'.
+	* src/cod/cidtoken.h: Handle `ForceBold' keyword.
+	Don't handle `ExpansionFactor'.
+
+2008-08-04  Bram Tassyns  <bramt@enfocus.be>
+
+	* src/cff/cffparse.c (cff_parse_fixed_scaled): Fix thinko which
+	resulted in incorrect scaling.  This fixes Savannah bug #23973.
+
+2008-08-04  Werner Lemberg  <wl@gnu.org>
+
+	Be more tolerant w.r.t. invalid entries in SFNT table directory.
+
+	* src/sfnt/ttload.c (check_table_dir): Ignore invalid entries and
+	adjust table count.
+	Add more trace messages.
+	(tt_face_load_font_dir): Updated.
+
+2008-07-30  Werner Lemberg  <wl@gnu.org>
+
+	* src/cff/cffgload.c (cff_decoder_parse_charstrings): No longer
+	assume that the first argument on the stack is the bottom-most
+	element.  Two reasons:
+
+	  o According to people from Adobe it is missing in the Type 2
+	    specification that pushing of additional, superfluous arguments
+	    on the stack is prohibited.
+
+	  o Acroread in general handles fonts differently, namely by popping
+	    the number of arguments needed for a particular operand (as a PS
+	    interpreter would do).  In case of buggy fonts this causes a
+	    different interpretation which of the elements on the stack are
+	    superfluous and which not.
+
+	Since there are CFF subfonts (embedded in PDFs) which rely on
+	Acroread's behaviour, FreeType now does the same.
+
+2008-07-27  Werner Lemberg  <wl@gnu.org>
+
+	Add extra mappings for `Tcommaaccent' and `tcommaaccent'.  This
+	fixes Savannah bug #23940.
+
+	* src/psnames/psmodule.c (WGL_EXTRA_LIST_SIZE): Rename to...
+	(EXTRA_GLYPH_LIST_SIZE): This.
+	Increase by 2.
+	(ft_wgl_extra_unicodes): Rename to...
+	(ft_extra_glyph_unicodes): This.
+	Add two code values.
+	(ft_wgl_extra_glyph_names): Rename to...
+	(ft_extra_glyph_names): This.
+	Add two glyphs.
+	(ft_wgl_extra_glyph_name_offsets): Rename to...
+	(ft_extra_glyph_name_offsets): This.
+	Add two offsets.
+
+	(ps_check_wgl_name, ps_check_wgl_unicode): Rename to...
+	(ps_check_extra_glyph_name, ps_check_extra_glyph_unicode): This.
+	Updated.
+	(ps_unicodes_init): Updated.
+
+2008-07-26  Werner Lemberg  <wl@gnu.org>
+
+	* src/cff/cffgload.c (cff_decoder_prepare,
+	cff_decoder_parse_charstrings): Improve debug output.
+
+2008-07-22  Martin McBride  <mmcbride@emtex.com>
+
+	* src/sfnt/ttcmap.c (tt_cmap4_validate, tt_cmap4_char_map_linear,
+	tt_cmap4_char_map_binary): Handle fonts which treat the last segment
+	specially.  According to the specification, such fonts would be
+	invalid but acroread accepts them.
+
+2008-07-16  Jon Foster  <Jon.Foster@cabot.co.uk>
+
+	* src/pfr/pfrdrivr.c (pfr_get_advance): Fix off-by-one error.
+
+	* src/base/ftcalc.c (FT_MulFix): Fix portability issue.
+
+	* src/sfnt/ttpost.c (MAC_NAME) [!FT_CONFIG_OPTION_POSTSCRIPT_NAMES]:
+	Fix compiler warning.
+
+2008-07-16  Werner Lemberg  <wl@gnu.org>
+
+	Handle CID-keyed fonts wrapped in an SFNT (with cmaps) correctly.
+
+	* src/cff/cffload.c (cff_font_load): Pass `pure_cff'.
+	Invert sids table only if `pure_cff' is set.
+	* src/cff/cffload.h: Updated.
+
+	* src/cff/cffobjs.c (cff_face_init): Updated.
+	Set FT_FACE_FLAG_CID_KEYED only if pure_cff is set.
+
+	* docs/CHANGES: Updated.
+
+2008-07-09  Werner Lemberg  <wl@gnu.org>
+
+	* src/truetype/ttpload.c (tt_face_load_loca): Handle buggy fonts
+	where num_locations < num_glyphs.  Problem reported by Ding Li.
+
+2008-07-05  Werner Lemberg  <wl@gnu.org>
+
+	Since FreeType uses `$(value ...)', we now need GNU make 3.80 or
+	newer.  This fixes Savannah bug #23648.
+
+	* configure: zsh doesn't like ${1+"$@"}.
+	Update needed GNU make version.
+	* builds/toplevel.mk: Check for `$(eval ...)'.
+	* docs/INSTALL.GNU, docs/INSTALL.CROSS, docs/INSTALL.UNIX: Document
+	it.
+
+2008-07-04  Werner Lemberg  <wl@gnu.org>
+
+	* src/raster/ftraster.c (Draw_Sweep): If span is smaller than one
+	pixel, only check for dropouts if neither start nor end point lies
+	on a pixel center.  This fixes Savannah bug #23762.
+
+2008-06-29  Werner Lemberg  <wl@gnu.org>
+
+	* Version 2.3.7 released.
+	=========================
+
+
+	Tag sources with `VER-2-3-7'.
+
+	* docs/CHANGES, docs/VERSION.DLL: Update documentation and bump
+	version number to 2.3.7.
+
+	* README, Jamfile (RefDoc), builds/win32/visualc/index.html,
+	builds/win32/visualc/freetype.dsp,
+	builds/win32/visualc/freetype.vcproj,
+	builds/win32/visualce/index.html,
+	builds/win32/visualce/freetype.dsp,
+	builds/win32/visualce/freetype.vcproj: s/2.3.6/2.3.7/, s/236/237/.
+
+	* include/freetype/freetype.h (FREETYPE_PATCH): Set to 7.
+
+	* builds/unix/configure.raw (version_info): Set to 9:18:3.
+
+	* docs/release: Updated.
+
+2008-06-28  Werner Lemberg  <wl@gnu.org>
+
+	* src/ftglyph.c (FT_Matrix_Multiply, FT_Matrix_Invert): Move to...
+	* src/ftcalc.c: Here.  This fixes Savannah bug #23729.
+
+2008-06-27  Werner Lemberg  <wl@gnu.org>
+
+	* src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
+	Horizontal_Gray_Sweep_Drop): Test for intersections which
+	degenerate to a single point can be ignored; this has been confirmed
+	by Greg Hitchcock from Microsoft.  (This was commented out code.)
+
+2008-06-26  Werner Lemberg  <wl@gnu.org>
+
+	Improve navigation in API reference.
+
+	* src/tools/docmaker/tohtml.py (html_header_3): Renamed to...
+	(html_header_6): This.
+	(html_header_3, html_header_3i, html_header_4, html_header_5,
+	html_header_5t): New strings.
+	(toc_footer_start, toc_footer_end): New strings.
+	(HtmlFormatter::html_header): Updated.
+	(HtmlFormatter::html_index_header, HtmlFormatter::html_toc_header):
+	New strings.
+	(HtmlFormatter::index_enter): Use `html_index_header'.
+	(HtmlFormatter::index_exit): Print `html_footer'.
+	(HtmlFormatter::toc_enter): Use `html_toc_header'.
+	(HtmlFormatter::toc_exit): Print proper footer.
+
+	Convert ~ to non-breakable space.
+
+	* src/tools/docmaker/tohtml.py (make_html_para): Implement it.
+	Update header files accordingly.
+
+2008-06-24  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	* builds/unix/configure.raw: Check type `ResourceIndex' explicitly
+	and define HAVE_TYPE_RESOURCE_INDEX if it is defined.  Mac OS X 10.5
+	bundles 10.4u SDK with MAC_OS_X_VERSION_10_5 macro but without
+	ResourceIndex type definition.  The macro does not inform the type
+	availability.
+	* src/base/ftmac.c: More parentheses are inserted to clarify the
+	conditionals to disable legacy APIs in `10.5 and later' cases.  If
+	HAVE_TYPE_RESOURCE_INDEX is not defined, ResourceIndex is defined.
+
+2008-06-24  Werner Lemberg  <wl@gnu.org>
+
+	* src/truetype/ttinterp.c (Ins_SCANTYPE): Don't check rendering
+	mode.
+
+	* src/raster/ftraster.c (Render_Glyph, Render_Gray_Glyph,
+	Draw_Sweep): No-dropout mode is value 2, not value 0.
+	(Draw_Sweep): Really skip dropout handling for no-dropout mode.
+
+2008-06-24  Werner Lemberg  <wl@gnu.org>
+
+	* src/psaux/psobjs.c (t1_builder_close_contour): Don't add contour
+	if it consists of one point only.  Based on a patch from Savannah
+	bug #23683 (from John Tytgat).
+
+2008-06-22  Werner Lemberg  <wl@gnu.org>
+
+	* src/truetype/ttgload.c (TT_Load_Glyph): Protect bytecode stuff
+	with IS_HINTED.
+
+	* docs/CHANGES: Updated.
+
+2008-06-22  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	* builds/unix/configure.raw: If CFLAGS has `-isysroot XXX' option
+	but LDFLAGS does not, import it to LDFLAGS.  The option is used to
+	specify non-default SDK on Mac OS X (e.g., universal binary SDK for
+	Mac OS X 10.4 on PowerPC platform).  Although Apple TechNote 2137
+	recommends to add the option only to CFLAGS, LDFLAGS should include
+	it because libfreetype.la is built with -no-undefined.  This fixes a
+	bug reported by Ryan Schmidt in MacPorts,
+	https://trac.macports.org/ticket/15331.
+
+2008-06-21  Werner Lemberg  <wl@gnu.org>
+
+	Enable access to the various dropout rules of the B&W rasterizer.
+	Pass dropout rules from the TT bytecode interpreter to the
+	rasterizer.
+
+	* include/freetype/ftimage.h (FT_OUTLINE_SMART_DROPOUTS,
+	FT_OUTLINE_EXCLUDE_STUBS): New flags for FT_Outline.
+
+	* src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
+	Horizontal_Gray_Sweep_Drop): Use same mode numbers as given in the
+	OpenType specification.
+	Fix mode 4 computation.
+	(Render_Glyph, Render_Gray_Glyph): Handle new outline flags.
+
+	* src/truetype/ttgload.c (TT_Load_Glyph) Convert scan conversion
+	mode to FT_OUTLINE_XXX flags.
+
+	* src/truetype/ttinterp.c (Ins_SCANCTRL): Enable ppem check.
+
+2008-06-19  Werner Lemberg  <wl@gnu.org>
+
+	* src/cff/cffobjs.c (cff_face_init): Compute final
+	`dict->units_per_em' value before assigning it to
+	`cffface->units_per_EM'.  Otherwise, CFFs without subfonts are
+	scaled incorrectly if the font matrix is non-standard.  This fixes
+	Savannah bug #23630.
+
+	* docs/CHANGES: Updated.
+
+2008-06-19  Werner Lemberg  <wl@gnu.org>
+
+	* src/type/t1objs.c (T1_Face_Init): Slightly improve algorithm fix
+	from 2008-06-19.
+
+2008-06-18  Werner Lemberg  <wl@gnu.org>
+
+	* src/type/t1objs.c (T1_Face_Init): Fix change from 2008-03-21.

+
+	* docs/CHANGES: Updated.
+
+2008-06-15  George Williams  <gww@silcom.com>
+
+	* src/otvalid/otvgpos.c (otv_MarkBasePos_validate): Set
+	`valid->extra2' to 1.  This is undocumented in the OpenType 1.5
+	specification.
+
+2008-06-15  Werner Lemberg  <wl@gnu.org>
+
+	* src/base/ftcalc.c (FT_MulFix) <asm>: Protect registers correctly
+	from clobbering.  Patch from Savannah bug report #23556.
+
+	* docs/CHANGES: Document it.
+
+2008-06-10  Werner Lemberg  <wl@gnu.org>
+
+	* autogen.sh: Add option `--install' to libtoolize.

+
+2008-06-09  VaDiM  <s_sliva@rambler.ru>
+
+	Support debugging on WinCE.  From Savannah patch #6536; this fixes

+	* builds/unix/configure.raw, builds/unix/freetype-config.in: Updated
+	for newer versions of autoconf and friends.
+
+2008-06-08  Werner Lemberg  <wl@gnu.org>
+
+	* src/type1/t1parse.h (T1_ParserRec): Make `base_len' and
+	`private_len' unsigned.
+
+	* src/type1/t1parse.c (read_pfb_tag): Make `asize' unsigned and read
+	it as such.
+	(T1_New_Parser, T1_Get_Private_Dict): Make `size' unsigned.
+
+
+	* src/base/ftstream.c (FT_Stream_Skip): Reject negative values.
+
+
+	* src/type1/t1load.c (parse_blend_design_positions): Check `n_axis'
+	for sane value.
+	Fix typo.
+
+
+	* src/psaux/psobjs.c (ps_table_add): Check `idx' correctly.
+
+
+	* src/truetype/ttinterp (Ins_SHC): Use BOUNDS() to check
+	`last_point'.
+
+
+	* src/sfnt/ttload.c (tt_face_load_max_profile): Limit
+	`maxTwilightPoints'.
+
+2008-06-06  Werner Lemberg  <wl@gnu.org>
+
+	* src/truetype/ttinterp.c (Ins_IP): Handle case `org_dist == 0'
+	correctly.  This fixes glyphs `t' and `h' of Arial Narrow at 12ppem.
+
+2008-06-03  Werner Lemberg  <wl@gnu.org>
+
+	* include/freetype/ftcache.h (FTC_FaceID): Change type back to
+	FT_Pointer.  Reported by Ian Britten <britten@caris.com>.
+
+2008-06-02  Werner Lemberg  <wl@gnu.org>
+
+	Emit header info for defined FreeType objects in reference.
+
+	* src/tools/docmaker/content.py (re_header_macro): New regexp.
+	(ContentProcessor::__init__): Initialize new dictionary `headers'.
+	(DocBlock::__init__): Collect macro header definitions.
+
+	* src/tools/docmaker/tohtml.py (header_location_header,
+	header_location_footer): New strings.
+	(HtmlFormatter::__init__): Pass `headers' dictionary.
+	(HtmlFormatter::print_html_field): Don't emit paragraph tags.
+	(HtmlFormatter::print_html_field_list): Emit empty paragraph.
+	(HtmlFormatter::block_enter): Emit header info.
+
+2008-06-01  Werner Lemberg  <wl@gnu.org>
+
+	* include/freetype/config/ftheader.h (FT_UNPATENTED_HINTING_H,
+	FT_INCREMENTAL_H): Added.
+
+2008-05-28  Werner Lemberg  <wl@gnu.org>
+
+	* src/tools/docmaker/sources.py (SourceBlock::__init__): While
+	looking for markup tags, return immediately as soon a single one is
+	found.
+
+2008-05-28  Werner Lemberg  <wl@gnu.org>
+
+	* src/truetype/ttinterp.c (Ins_MD): The MD instruction also uses
+	original, unscaled input values.  Confirmed by Greg Hitchcock from
+	Microsoft.
+
+2008-05-27  Werner Lemberg  <wl@gnu.org>
+
+	* src/tools/docmaker/tohtml.py (block_footer_start,
+	block_footer_middle): Beautify output.
+
+2008-05-25  Werner Lemberg  <wl@gnu.org>
+
+	* src/raster/ftraster.c (fc_black_render): Return 0 when we are
+	trying to render into a zero-width/height bitmap, not an error code.
+
+	* src/truetype/ttgload.c (load_truetype_glyph): Move initialization
+	of the graphics state for subglyphs to...
+	(TT_Hint_Glyph): This function.
+	Hinting instructions for a composite glyph apparently refer to the
+	just hinted subglyphs, not the unhinted, unscaled outline.  This
+	seems to fix Savannah bugs #20973 and (at least partially) #23310.
+
+2008-05-20  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	* src/base/ftmac.c (FT_New_Face_From_Suitcase): Check if valid
+	`aface' is returned by FT_New_Face_From_FOND().  The patch was
+	proposed by an anonymous reporter of Savannah bug #23204.
+
+2008-05-18  Werner Lemberg  <wl@gnu.org>
+
+	* src/pshinter/pshalgo.c (ps_hints_apply): Reset scale values after
+	correction for pixel boundary.  Without this patch, the effect can
+	be cumulative under certain circumstances, making glyphs taller and
+	taller after each call.  This fixes Savannah bug #19976.
+
+2008-05-18  Werner Lemberg  <wl@gnu.org>
+
+	* src/base/ftdebug.c (FT_Message, FT_Panic): Send output to stderr.
+	This fixes Savannah bug #23280.
+
+	* docs/CHANGES: Updated.
+
+2008-05-18  David Turner  <david@freetype.org>
+
+	* src/psnames/psmodule.c (ft_wgl_extra_unicodes,
+	ft_wgl_extra_glyph_names, ft_wgl_extra_glyph_name_offsets,
+	ps_check_wgl_name, ps_check_wgl_unicode): Use `static' to make
+	declarations non-global.
+
+	* src/type1/t1load.c: Add missing comment.
+
+2008-05-17  Sam Hocevar  <samh>
+
+	* src/truetype/ttgload.c (TT_Load_Simple_Glyph): Handle zero-contour
+	glyphs correctly.  Patch from Savannah bug #23277.
+
+2008-05-16  Werner Lemberg  <wl@gnu.org>
+
+	* docs/CHANGES: Updated.
+
+2008-05-16  Sergey Tolstov  <stolstov@esri.com>
+
+	Improve support for WGL4 encoded fonts.
+
+	* src/psnames/psmodule.c (WGL_EXTRA_LIST_SIZE): New macro.
+	(ft_wgl_extra_unicodes, ft_wgl_extra_glyph_names,
+	ft_wgl_extra_glyph_name_offsets): New arrays.
+	(ps_check_wgl_name, ps_check_wgl_unicode): New functions.
+	(ps_unicodes_init): Use them to add additional Unicode mappings.
+
+2008-05-15  Werner Lemberg  <wl@gnu.org>
+
+	* src/psaux/t1decode.c (t1_decoder_parse_charstrings)
+	<op_closepath>: `closepath' without a path is a no-op, not an error
+	(cf. the PS reference manual).
+
+	Reported by Martin McBride.
+
+2008-05-15  Werner Lemberg  <wl@gnu.org>
+
+	* builds/toplevel.mk (CONFIG_GUESS, CONFIG_SUB): Updated.
+
+2008-05-15  Werner Lemberg  <wl@gnu.org>
+
+	* src/type1/t1load.c (parse_subrs): Accept fonts with a subrs array
+	which contains a single but empty entry.  This is technically
+	invalid (since it must end with `return'), but...
+
+	Reported by Martin McBride.
+
+2008-05-14  Werner Lemberg  <wl@gnu.org>
+
+	Finish fix of scaling bug of CID-keyed CFF subfonts.
+
+	* include/freetype/internal/ftcalc.h, src/base/ftcalc.c
+	(FT_Matrix_Multiply_Scaled, FT_Vector_Transform_Scaled): New
+	functions.
+
+	* src/cff/cffobjs.h (CFF_Internal): New struct.  It is used to
+	provide global hinting data for both the top-font and all subfonts
+	(with proper scaling).
+
+	* src/cff/cffobjs.c (cff_make_private_dict): New function, using
+	code from `cff_size_init'.
+	(cff_size_init, cff_size_done, cff_size_select, cff_size_request):
+	Use CFF_Internal and handle subfonts.
+	(cff_face_init): Handle top-dict and subfont matrices correctly;
+	apply some heuristic in case of unlikely matrix concatenation
+	results.  This has been discussed with people from Adobe (thanks
+	goes mainly to David Lemon) who confirm that the CFF specs are fuzzy
+	and not correct.
+
+	* src/cff/cffgload.h (cff_decoder_prepare): Add `size' argument.
+
+	* src/cff/cffgload.c (cff_builder_init): Updated.
+	(cff_decoder_prepare): Handle hints globals for subfonts.

+	* docs/CHANGES: Document it.
+
+2008-05-04  Werner Lemberg  <wl@gnu.org>
+
+	First steps to fix the scaling bug of CID-keyed CFF subfonts,
+	reported by Ding Li on 2008/03/28 on freetype-devel.
+
+	* src/base/cff/cffparse.c (power_tens): New array.
+	(cff_parse_real): Rewritten to introduce a fourth parameter which
+	returns the `scaling' of the real number so that we have no
+	precision loss.  This is not used yet.
+	Update all callers.
+	(cff_parse_fixed_thousand): Replace with...
+	(cff_parse_fixed_scaled): This function.  Update all callers.
+
+2008-05-03  Werner Lemberg  <wl@gnu.org>
+
+	* src/base/ftobjs.c (FT_Load_Glyph): Call the auto-hinter without
+	transformation since it recursively calls FT_Load_Glyph.  This fixes
+	Savannah bug #23143.
+
+2008-04-26  Werner Lemberg  <wl@gnu.org>
+
+	* include/freetype/internal/psaux.h (T1_BuilderRec): Mark `scale_x'
+	and `scale_y' as obsolete since they aren't used.
+	* src/psaux/psobjs.c (t1_builder_init): Updated.
+
+	* src/cff/cffgload.h (CFF_Builder): Mark `scale_x' and `scale_y' as

+2008-04-14  Werner Lemberg  <wl@gnu.org>
+
+	* src/pcf/pcfdrivr.c (PCF_Face_Init): Protect call to

+	bug #22909.
+
+2008-04-13  Werner Lemberg  <wl@gnu.org>
+
+	* src/psaux/psconv.c (PS_Conv_ToFixed): Increase precision if
+	integer part is zero.
+
+2008-04-01  Werner Lemberg  <wl@gnu.org>
+
+	Fix compilation with g++ 4.1 (with both `single' and `multi'
+	targets).
+
+	* src/base/ftobjs.c (FT_Open_Face): Don't define a variable in block
+	which is crossed by a `goto'.
+
+	* src/otvalid/otvalid.h (otv_MATH_validate): Add prototype.
+
+2008-03-31  Werner Lemberg  <wl@gnu.org>
+
+	Fix support for subsetted CID-keyed CFFs.

+
+
+	Fix CFF font matrix calculation and improve precision.
+
+	* src/cff/cffparse.c (cff_parse_real): Increase precision if integer
+	part is zero.
+	(cff_parse_font_matrix): Simplify computation of `units_per_em';
+	this prevents overflow also.
+
+
+	Support FT_Get_CID_Registry_Ordering_Supplement for PS CID fonts.
+
+	* src/cid/cidriver.c: Include FT_SERVICE_CID_H.
+	(cid_get_ros): New function.

+2008-03-23  Werner Lemberg  <wl@gnu.org>
+
+	Adjustments for Visual C++ 8.0, as reported by Rainer Deyke.
+
+	* builds/compiler/visualc.mk (CFLAGS): Remove /W5.
+	(ANSIFLAGS): Add _CRT_SECURE_NO_DEPRECATE.
+
+2008-03-21  Laurence Darby  <ldarby>
+
+	* src/type1/t1objs.c (T1_Face_Init): Use `/Weight'.  Patch from
+	Savannah bug #22675.
+
+2008-03-13  Derek Clegg  <dclegg@apple.com>
+
+	* src/truetype/ttgxvar.c (TT_Get_MM_Var): Fix named style loop.

+
+	* docs/CHANGES: Updated.
+
+2008-02-29  Wolf
+
+	Add build support for symbian platform.  From Savannah bug #22440.
+
+	* builds/symbian/*: New files.
+
+2008-02-21  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	* src/base/ftmac.c (parse_fond): Fix a bug of PostScript font name
+	synthesis.  For any face of a specified FOND, always the name for
+	the first face was used.  Except of a FOND that refers multiple
+	Type1 font files, wrong synthesized font names are not used at all,
+	so this is an invisible bug.  A few limit checks are added too.
+
+	* builds/mac/ftmac.c: Ditto.
+
+2008-02-21  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	* builds/unix/configure.raw: Split compiler option to link Carbon
+	frameworks to one option for CoreServices framework and another
+	option for ApplicationServices framework.  The split options can be
+	managed by GNU libtool to avoid unrequired duplication when FreeType
+	is linked with other applications.  Suggested by Daniel Macks,
+	Savannah bug #22366.
+
+2008-02-18  Victor Stinner  <victor.stinner@haypocalc.com>
+
+	* src/truetype/ttinterp.c (Ins_IUP): Check number of points.  Fix

+	Check for valid callback pointers.
+
+2008-02-15  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	* src/base/ftmac.c (FT_New_Face_From_SFNT): Check the sfnt resource
+	handle by its value instead of ResError(), fix provided by Deron
+	Kazmaier.  According to the Resource Manager Reference,
+	GetResource(), Get1Resource(), GetNamedResource(),
+	Get1NamedResource() and RGetResource() set noErr but return NULL
+	handle when they can not find the requested resource.  These
+	functions never return undefined values, so it is sufficient to
+	check if the handle is not NULL.
+
+	* builds/mac/ftmac.c (FT_New_Face_From_SFNT): Ditto.
+
+2008-02-14  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	* src/base/ftbase.c: <ftmac.c> is replaced by "ftmac.c" as other
+	inclusion styles.  Now it always includes src/base/ftmac.c;
+	builds/mac/ftmac.c is never included in any configuration.
+
+	* builds/unix/configure.raw: Print warning if configure is executed
+	with options to specify Carbon functionalities explicitly.
+
+	* docs/INSTALL.MAC: Note that legacy builds/mac/ftmac.c is not
+	included automatically and manual replacement is required.
+
+2008-02-11  Werner Lemberg  <wl@gnu.org>
+
+	* builds/modules.mk (CLOSE_MODULE, REMOVE_MODULE), builds/detect.mk
+	(dos_setup), builds/freetype.mk (clean_project_dos,

+
+2008-01-18  Sylvain Pasche  <sylvain.pasche@gmail.com>
+
+	* src/base/ftlcdfil.c (_ft_lcd_filter_legacy): Updated comment to

+
+2008-01-16  Werner Lemberg  <wl@gnu.org>
+
+	* src/raster/ftraster.c (ft_black_render): Check `outline' before

+
+2008-01-12  Werner Lemberg  <wl@gnu.org>
+
+	* src/raster/ftraster.c (FT_CONFIG_OPTION_5_GRAY_LEVELS): Remove.
+
+2008-01-12  Allan Yang, Jian Hua - SH  <Allan.Yang@fmc.fujitsu.com>
+
+	* src/raster/ftraster.c (ft_black_init)
+	[FT_RASTER_OPTION_ANTI_ALIASING]: Fix compilation.
+
+2008-01-10  Werner Lemberg  <wl@gnu.org>
+
+	* src/truetype/ttgload.c (load_truetype_glyph): Handle the case
+	where the number of contours in a simple glyph is zero (and which
+	does contain an entry in the `glyf' table).  This fixes Savannah bug
+	#21990.
+
+2008-01-04  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	Formatting suggested by Sean McBride.
+
+	* builds/mac/ftmac.c: Formatting (tab expanded).

+	* src/base/ftmac.c: Ditto.
+
+2007-12-30  Werner Lemberg  <wl@gnu.org>
+

+	correctly.
+
+2007-12-21  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	Improvement of POSIX resource-fork accessor to load unsorted
+	references in a resource.  In HelveLTMM (resource-fork PostScript
+	Type1 font bundled with Mac OS X since 10.3.x), the appearance order
+	of PFB chunks is not sorted; sorting the chunks by reference IDs is
+	required.
+
+	* include/freetype/internal/ftrfork.h (FT_RFork_Ref): New structure
+	type to store a pair of reference ID and offset to the chunk.
+
+	* src/base/ftrfork.c (ft_raccess_sort_ref_by_id): New function to
+	sort FT_RFork_Ref by their reference IDs.
+
+	(FT_Raccess_Get_DataOffsets): Returns an array of offsets that is
+	sorted by reference ID.
+
+2007-12-14  Werner Lemberg  <wl@gnu.org>
+
+	* src/cff/cffparse.c (cff_parse_real): Don't apply `power_ten'
+	division too early; otherwise the most significant digit(s) of the
+	final result are lost as the value is truncated to an integer.  This
+	fixes Savannah bug #21794 (where the patch has been posted too).
+
+2007-12-06  Fix  <4d876b82@gmail.com>
+
+	Pass options from one configure script to another as-is (not
+	expanded).  This is needed for options like
+	--includedir='${prefix}/include'.
+
+	* builds/unix/detect.mk, configure: Prevent argument expansion in
+	call to the (real) `configure' script.
+
+2007-12-06  Werner Lemberg  <wl@gnu.org>
+
+	* src/truetype/ttgload.c (load_truetype_glyph): Fix compilation if
+	TT_USE_BYTECODE_INTERPRETER isn't defined.
+
+2007-12-06  Werner Lemberg  <wl@gnu.org>
+
+	There exist CFFs which contain opcodes for the Type 1 operators
+	`hsbw' and `closepath' which are both invalid in Type 2 charstrings.
+	However, it doesn't harm to support them.
+
+	* src/cff/cffgload.c (CFF_Operator): Add `cff_op_hsbw' and
+	`cff_op_closepath.'
+	(cff_argument_counts): Ditto.
+
+	(cff_decoder_parse_charstrings): Handle Type 1 opcodes 9 (closepath)
+	and 13 (hsbw) which are invalid in Type 2 charstrings.
+
+2007-12-06  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	* src/base/ftrfork.c (raccess_guess_darwin_newvfs): New function to
+	support new pathname syntax `..namedfork/rsrc' to access a resource
+	fork on Mac OS X.  The legacy syntax `/rsrc' does not work on
+	case-sensitive HFS+.
+	(raccess_guess_darwin_hfsplus): Fix a bug in the calculation of
+	buffer size to store a pathname.
+	* include/freetype/internal/ftrfork.h: Increment the number of
+	resource fork guessing rule.
+
+2007-12-06  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	* builds/unix/configure.raw: Improve the compile tests to search

+	* builds/mac/ftmac.c: Import fixes for Carbon incompatibilities
+	proposed by Sean McBride from src/base/ftmac.c (see 2007-11-16).
+
+2007-12-06  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	The documents and comments for Mac OS X are improved by Sean

+
+2007-12-04  Werner Lemberg  <wl@gnu.org>
+
+	* src/cff/cffload.c (cff_subfont_load): Don't use logical OR to

+
+2007-12-04  Graham Asher  <graham.asher@btinternet.com>

+
+2007-12-04  Sean McBride  <sean@rogue-research.com>

+	warning.
+
+2007-11-20  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	Fix MacOS legacy font support by Masatake Yamato on Mac OS X.  It is
+	not working since 2.3.5.  In FT_Open_New(), if FT_New_Stream()
+	cannot mmap() the specified file and cannot seek to head of the
+	specified file, it returns NULL stream and FT_Open_New() returns the
+	error immediately.  On MacOS, most legacy MacOS fonts fall into such
+	a scenario because their data forks are zero-sized and cannot be
+	sought.  To proceed to guessing of resource fork fonts, the
+	functions for legacy MacOS font must properly handle the NULL stream
+	returned by FT_New_Stream().
+
+	* src/base/ftobjs.c (IsMacBinary): Return error
+	FT_Err_Invalid_Stream_Operation immediately when NULL stream is
+	passed.
+	(FT_Open_Face): Even when FT_New_Stream() returns an error, proceed
+	to fallback.  Originally, legacy MacOS font is tested in the cases
+	of FT_Err_Invalid_Stream_Operation (occurs when data fork is empty)
+	or FT_Err_Unknown_File_Format (occurs when AppleSingle header or
+	.dfont header is combined).  Now the case of
+	FT_Err_Cannot_Open_Stream is included.
+
+	* src/base/ftrfork.c (FT_Raccess_Guess): When passed stream is NULL,
+	skip FT_Stream_Seek(), which seeks to the head of stream, and
+	proceed to unit testing of raccess_guess_XXX().  FT_Stream_Seek()
+	for a NULL stream causes a Bus error on Mac OS X.
+	(raccess_guess_apple_double): Return FT_Err_Cannot_Open_Stream
+	immediately if passed stream is NULL.
+	(raccess_guess_apple_single): Ditto.
+
+2007-11-16  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	Fix for Carbon incompatibilities since Mac OS X 10.5,
+	proposed by Sean McBride.
+
+	* doc/INSTALL.MAC: Comment on MACOSX_DEPLOYMENT_TARGET.
+
+	* include/freetype/ftmac.h: Deprecate FT_New_Face_From_FOND and
+	FT_GetFilePath_From_Mac_ATS_Name.  Since Mac OS X 10.5, calling
+	Carbon functions from a forked process is classified as unsafe
+	by Apple.  All Carbon-dependent functions should be deprecated.
+
+	* src/base/ftmac.c: Use essential header files

+
+	For the index in the segment of resource fork, new portable
+	type ResourceIndex is introduced for better compatibility.
+	This type is since Mac OS X 10.5, so it is defined as short
+	when built on older platforms.
+
+	(FT_ATSFontGetFileReference): If build target is only the systems
+	10.5 and newer, it calls Apple genuine ATSFontGetFileReference().
+
+	(FT_GetFile_From_Mac_ATS_Name): Return an error if system is 10.5

+	instead.
+
+	(TT_CMap14Rec): Provide array and auxiliary data for result.

+

+
+
+	* Version 2.3.1 released.
+	=========================
+
+
+	Tag sources with `VER-2-3-1-FINAL'.
+
+	* builds/win32/visualc/freetype.dsp,
+	builds/win32/visualc/freetype.vcproj: s/230/231/.
+	* builds/win32/visualc/index.html: s/221/231/.
+
+	* vms_make.com: Add `ftgasp'.
+
+2007-01-30  David Turner  <david@freetype.org>
+
+	Tag sources with VER-2-3-1 to prepare release.
+
+	* include/freetype/freetype.h (FREETYPE_PATCH): Set to 1.
+
+	* docs/VERSION.DLL, docs/release, README, Jamfile (RefDoc):
+	s/2.3.0/2.3.1/.
+
+	* builds/unix/configure.raw (version_info): Set to 9:12:3.
+
+
+	* src/autofit/aftypes.h (AF_USE_WARPER), src/autofit/afloader.c
+	(af_loader_load_g): Disable the warper (i.e., the light hinting
+	improvements) to make a 2.3.1 bugfix release before introducing a
+	new feature.  This should give us more time to tune and improve the
+	warper for the next release.
+
+	* docs/CHANGES: Update accordingly.
+
+2007-01-25  David Turner  <david@freetype.org>
+
+	For light auto-hinting, improve glyph advance widths and resurrect
+	normal/full hinting to its normal quality.
+
+	* src/autofit/afhints.h (AF_GlyphHintsRec): New members `xmin_delta'
+	and `xmax_delta'.
+	* src/autofit/afhints.c (af_glyph_hints_reload): Reset `xmin_delta'
+	and `xmax_delta'.
+
+	* src/autofit/afloader.c (af_loader_load_g) <AF_USE_WARPER>: Replace

+	normal mode.
+
+	* src/autofit/afwarp.c (AF_WarpScore): Fine-tune again.

+
+2007-01-25  Werner Lemberg  <wl@gnu.org>
+
+	* src/cff/cffload.c (cff_index_get_pointers): Handle last entry
+	correctly in a sanity check.  Since this function is only used to
+	load local and global functions, any charstring that called the last
+	local/global function would fail otherwise.  This fixes Savannah bug
+	#18867.
+
+	* docs/CHANGES: Document it.
+
+2007-01-23  David Turner  <david@freetype.org>
+
+	* src/truetype/ttobjs.c (tt_size_ready_bytecode): Fix typo that
+	prevented compilation when disabling both the unpatented and the
+	bytecode interpreter in the TrueType font driver.
+
+
+	Fix and enable the warper to improve `light' hinting mode.  This is
+	not necessarily a final version, but it seems to work well.
+
+	* src/autofit/aflatin.c (af_latin_hints_init) [AF_USE_WARPER]:
+	Disable code.
+	(af_latin_hints_apply) [AF_USE_WARPER]: Handle FT_RENDER_MODE_LIGHT.

+	and `X2'.

+
+2007-01-21  George Williams  <gww@silcom.com>

+	points.
+
+2007-01-21  Werner Lemberg  <wl@gnu.org>
+
+	* src/sfnt/ttmtx.c (tt_face_get_metrics)

+
+2007-01-15  Detlef Würkner  <TetiSoft@apg.lahn.de>
+
+	* builds/amiga/makefile, builds/amiga/makefile.os4,

+
+	* builds/amiga/include/freetype/config/ftconfig.h: Synchronize.
+
+2007-01-14  Detlef Würkner  <TetiSoft@apg.lahn.de>

+
+2007-01-13  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

+
+2007-01-13  Werner Lemberg  <wl@gnu.org>

+
+2007-01-10  David Turner  <david@freetype.org>
+
+	* all-sources: Tag all sources with VER-2-3-0-RC1 and

+2007-01-04  David Turner  <david@freetype.org>
+
+	* src/pfr/pfrobjs.c (pfr_face_init): Detect non-scalable fonts

+
+
+	Don't extract the metrics table from the SFNT font file.  Instead,

+
+	* include/freetype/internal/tttypes.h (TT_FaceRec): Add members
+	`horz_metrics_offset' and `vert_metrics_offset'.

+
+
+	* src/sfnt/ttcmap.c (tt_cmap4_validate): Slight optimization.
+
+

+	(ft_black_init): Don't initialize `count_table'.
+	(ft_black_reset): Use the render pool.  This saves about 6KB of
+	heap space for each FT_Library instance.
+
+	* src/smooth/ftgrays.c (TRaster): Replaced with...

+	src/sfnt/ttmtx.c, src/sfnt/ttsbit.c, src/sfnt/ttsbit.h,
+	src/truetype/ttpload.c, include/freetype/config/ftoption.h: Remove

+
+	* src/pshinter/pshalgo.c (psh_glyph_interpolate_normal_points):
+	Remove a typo that results in no hinting and a memory leak with some

+2006-12-15  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	* src/base/ftmac.c: Specialized for Mac OS X only.
+	* builds/unix/ftconfig.in: Fixed for ppc64 missing Carbon framework.

+2006-12-09  Werner Lemberg  <wl@gnu.org>
+
+	* builds/*/*def.mk, builds/*/detect.mk (CAT): Define to either `cat'

+
+2006-12-08  Werner Lemberg  <wl@gnu.org>
+
+	* builds/toplevel.mk (dist): Extract version number from freetype.h.
+
+2006-12-08  Vladimir Volovich  <vvv@vsu.ru>
+
+	* src/tools/apinames.c (State): Remove final comma in structure --
+	xlc v5 under AIX 4.3 doesn't like this.

+
+2006-11-18  Werner Lemberg  <wl@gnu.org>
+
+	Because FT_Load_Glyph expects CID values for CID-keyed fonts, the

+	This patch fixes Savannah bug #18301.
+
+	* src/base/ftobjs.c (FT_Load_Glyph): Don't check `glyph_index'.
+	* src/bdf/bdfdrivr.c (BDF_Glyph_Load), src/cff/cffgload.c

+
+2006-11-13  David Turner  <david@freetype.org>
+
+	* src/truetype/ttinterp.c (FIX_BYTECODE): Undefine.  The interpreter
+	`enhancements' are still too buggy for general use.
+
+	* src/base/ftlcdfil.c: Add support for FT_FORCE_LIGHT_LCD_FILTER and
+	FT_FORCE_LEGACY_LCD_FILTER at compile time.  Define these macros

+
+2006-11-10  David Turner  <david@freetype.org>
+
+	* src/smooth/ftsmooth.c: API change for the LCD
+	filter.  The FT_LcdFilter value is an enumeration describing which
+	filter to apply, with new values FT_LCD_FILTER_LIGHT and
+	FT_LCD_FILTER_LEGACY (the latter implements the LibXft original
+	algorithm which produces strong color fringes for everything
+	except very-well hinted text).
+
+	* include/freetype/ftlcdfil.h (FT_Library_SetLcdFilter): Change
+	second parameter to an enum type.
+

+	improve the handling of serif fonts and of LCD/LCD_V hinting modes.
+	(af_latin_hints_compute_edges): Fix typo.
+	(af_latin_compute_stem_width): Take better care of diagonal stems.
+
+2006-11-09  David Turner  <david@freetype.org>

+	* src/pshinter/pshalgo.c (psh_glyph_compute_inflections): Fix
+	typo which created a variable-used-before-initialized bug.
+
+2006-11-07  Zhe Su  <james.su@gmail.com>

+	* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Handle vertical layout
+	also.
+
+2006-11-03  Werner Lemberg  <wl@gnu.org>

+
+	Add a few tweaks to better handle serif fonts.
+	Add more debugging messages.
+
+	* src/autofit/aflatin.c (af_latin_hints_compute_edges): Ignore
+	segments that are less than 1.5 pixels high.  This gets rid of
+	*many* corner cases with serifs.
+	(af_latin_align_linked_edge): Add logging message.
+	(af_latin_hint_edges): Use AF_HINTS_DO_BLUES.
+	Add logging messages.

+
+	* src/autofit/afmodule.c [AF_DEBUG]: Add _af_debug,
+	_af_debug_disable_blue_hints, and _af_debug_hints variables.
+
+	* src/autofit/aftypes.h (AF_LOG) [AF_DEBUG]: Use _af_debug.
+	Update external declarations.
+	(af_corner_orientation, af_corner_is_flat): Replaced by...
+
+	* include/freetype/internal/ftcalc.h (ft_corner_orientation,
+	ft_corner_is_flat): These declarations.
+
+	* src/autofit/afangles.c (af_corner_orientation, af_corner_is_flat):
+	Comment out.  Replaced by...
+
+	* src/base/ftcalc.h (ft_corner_orientation, ft_corner_is_flat):
+	These functions.  Update all callers.

+
+	* src/autofit/afhints.c: Include FT_INTERNAL_CALC_H.
+	(af_direction_compute): Add a missing FT_ABS call.  This bug caused

+
+	* src/autofit/afhints.h (AF_HINTS_DO_BLUES): New macro.
+
+	* src/autofit/afloader.c (af_loader_init, af_loader_done)

+	(psh_corner_is_flat, psh_corner_orientation): Use ft_corner_is_flat
+	and ft_corner_orientation.

+
+	* src/base/ftoutln.c (FT_Outline_Get_Orientation): Re-implement to
+	better deal with broken Asian fonts with strange glyphs, having
+	self-intersections and other peculiarities.  The used algorithm is
+	based on the nonzero winding rule.
+
+2006-10-23  David Turner  <david@freetype.org>
+
+	Speed up the CFF font loader.  With some large CFF fonts,
+	FT_Open_Face is now more than three times faster.
+
+	* src/cff/cffload.c (cff_get_offset): Removed.
+	(cff_new_index): Inline functionality of `cff_get_offset'.
+	(cff_charset_compute_cids, cff_charset_free_cids): New functions.
+	(cff_charset_done): Call `cff_charset_free_cids'.
+	(cff_charset_load): Call `cff_charset_compute_cids'.

+
+	* docs/INSTALL.CROSS: New document file for cross-building.
+
+	* builds/unix/configure.raw: Preliminary cross-building support.
+	Find native C compiler and pass it by CC_BUILD, and

+	Also suffix for target executable is passed by EXEEXT.
+
+	* builds/unix/unix-cc.in (CCraw_build, E_BUILD): New variables to
+	build `apinames' which runs on building system.  They are set by
+	CC_BUILD and EXEEXT_BUILD.
+
+	* builds/exports.mk (APINAMES_EXE): Change the extension for
+	apinames from the suffix for target (E) to that for building host
+	(E_BUILD).
+
+2006-10-12  Werner Lemberg  <wl@gnu.org>
+
+	* docs/INSTALL.UNX, docs/UPGRADE.UNX: Renamed to...
+	* docs/INSTALL.UNIX, docs/UPGRADE.UNIX: This.  Update all documents
+	which reference those files.
+
+2006-10-12  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	* builds/unix/configure.raw (FT2_EXTRA_LIBS): New variable.  It is
+	embedded in freetype2.pc and freetype-config.  Use it to record

+
+	* builds/unix/freetype2.in: Embed FT2_EXTRA_LIBS.
+

+
+2006-10-01  Werner Lemberg  <wl@gnu.org>
+
+	* src/base/ftbase.c: Undo change from 2006-09-30.

+
+2006-09-30  David Turner  <david@freetype.org>

+
+2006-09-27  David Turner  <david@freetype.org>
+
+	* include/freetype/freetype.h (FT_FREETYPE_PATCH): Set to 2.
+
+
+	Add a new API to support color filtering of subpixel glyph bitmaps.
+	In a default build, the function `FT_Library_SetLcdFilter' returns
+	`FT_Err_Unimplemented_Feature'; you need to #define
+	FT_CONFIG_OPTION_SUBPIXEL_RENDERING in ftoption.h to compile the
+	real implementation.
+
+	* include/freetype/ftlcdfil.h, src/base/ftlcdfil.c: New files.

+
+2006-09-26  David Bustin

+
+	* include/freetype/config/ftoption.h, devel/ftoption.h
+	(FT_CONFIG_OPTION_SUBPIXEL_RENDERING): New macro to control whether
+	we want to compile LCD-optimized rendering code (à la ClearType) or
+	not.  The macro *must* be disabled in default builds of the library
+	for patent reasons.
+
+	* src/smooth/ftsmooth.c (ft_smooth_render_generic): Disable
+	LCD-specific rendering when FT_CONFIG_OPTION_SUBPIXEL_RENDERING
+	isn't defined at compile time.  This only changes the content of the
+	rendered glyph to match the one of normal gray-level rendering,
+	hence clients should not need to be modified.
+
+	* docs/CHANGES: Updated.
+
+2006-09-18  Garrick Meeker  <garrick@digitalanarchy.com>
+
+	* src/base/ftmac.c (FT_New_Face_From_FOND): Fall back to SFNT if
+	LWFN fails and both are available.
+
+2006-09-11  David Turner  <david@freetype.org>
+
+	* src/sfnt/sfobjs.c (tt_face_get_name): Support some fonts which
+	report their English names through an Apple Roman
+	(platform,encoding) pair, with language_id != English.
+
+	If the font uses another name entry with language_id == English, it
+	will be selected correctly, though.
+
+	* src/truetype/ttobjs.c (tt_face_init): Add unpatented hinting
+	selection for `mingli.ttf'.
+
+2006-09-05  Werner Lemberg  <wl@gnu.org>
+

+	`HAN NOM B.ttf').
+
+	* src/smooth/ftgrays.c [GRAYS_USE_GAMMA]: Really remove all code.
+
+2006-09-05  David Turner  <david@freetype.org>

+	(gray_set_cell): Rewrite.
+	(gray_start_cell): Apply offsets to `ras.ex' and `ras.ey'.
+	(gray_render_span): Don't use FT_MEM_SET for small values.
+	(gray_dump_cells) [DEBUG_GRAYS]: New function.
+	(gray_sweep): Avoid buffer overwrites when to drawing the end of a
+	bitmap scanline.
+	(gray_convert_glyph): Fix speed-up.

+2006-06-25  Jens Claudius  <jens.claudius@yahoo.com>
+
+	The Type 1 parser now skips over top-level procedures as required

+2006-05-17  David Turner  <david@freetype.org>
+
+	This is a major patch used to drastically improve the performance of

+
+	[cff] Make Adobe CFF engine work correctly on 64bit hosts.
+
+	Reported by numerous people on the `freetype-devel' list.  Without
+	this fix, glyphs aren't properly aligned on a common baseline.
+
+	On 64bit systems, `FT_Pos' expands to `long int', having a width of
+	64bit.  `CF2_Fixed' expands to `int' which is normally 32bit wide on
+	64bit hosts also.  Wrong casts filled up the blues arrays with
+	incorrect values.  Note that all blues values are accessed with the
+	`cf2_blueToFixed' macro which handles the 64bit to 32bit conversion.
+
+	* src/cff/cf2ft.h (cf2_getBlueValues, cf2_getOtherBlues,
+	cf2_getFamilyBlues, cf2_getFamilyOtherBlues): Use `FT_Pos' for
+	`data', not `CF2_Fixed'.
+	* src/cff/cf2ft.c (cf2_getBlueValues, cf2_getOtherBlues,
+	cf2_getFamilyBlues, cf2_getFamilyOtherBlues): Updated.
+	* src/cff/cf2blues.c (cf2_blues_init): Updated.
+
+2013-05-04  Werner Lemberg  <wl@gnu.org>
+
+	More fixes for clang's `sanitize' feature.
+
+	* src/base/ftcalc.c (FT_DivFix): Use unsigned values for
+	computations which use the left shift operator and convert to signed
+	as the last step.
+	* src/base/fttrigon.c (ft_trig_prenorm, FT_Vector_Rotate,
+	FT_Vector_Length, FT_Vector_Polarize): Ditto.

+	FT_PEEK_LONG_LE, FT_PEEK_OFF3_LE): Use unsigned values for
+	computations and convert to signed as the last step.
+
+	* src/cff/cf2fixed.h (cf2_intToFixed, cf2_fixedToInt,
+	cf2_fracToFixed): Avoid shifts of negative values.
+	(cf2_intToFrac, cf2_fixedToFrac, cf2_fixedTo26Dot6): Removed,
+	unused.
+
+	* src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdEXTENDEDNMBR,
+	default>: Use unsigned values for computations and convert to signed
+	as the last step.
+	Use proper types in tracing messages.
+
+	* src/cff/cffgload.c (cff_decoder_parse_charstrings): Use unsigned
+	values for computation of operands and convert to signed as the last
+	step.
+	Use proper type in tracing message.
+
+2013-05-03  Werner Lemberg  <wl@gnu.org>

+
+2013-04-13  Werner Lemberg  <wl@gnu.org>
+
+	[cff] Add a new Type 2 interpreter and hinter.
+
+	This work, written by Dave Arnold <darnold@adobe.com> and fully
+	integrated into FreeType by me, is a donation by Adobe in
+	collaboration with Google.  It is vastly superior to the old CFF
+	engine, and it will replace it soon.  Right now, it is still off by
+	default, and you have to explicitly select it using the new
+	`hinting-engine' property of the cff driver.
+
+	For convenience, (most of) the new files are committed separately.
+
+	* include/freetype/config/ftheader.h (FT_CFF_DRIVER_H): New macro.
+	* include/freetype/ftcffdrv.h: New file to access CFF driver
+	properties.

+	* src/cff/cffgload.h (CFF_SubFont): New member `current_subfont'.
+	* src/cff/cffobjs.h (CFF_DriverRec): New members `hinting_engine'
+	and `no_stem_darkening'.
+	* src/cff/cfftypes.h (CFF_FontRec): New member `cf2_instance'.
+
+	* src/cff/cff.c: Include new files.
+	* src/cff/cffdrivr.c (cff_property_set, cff_property_get): Handle
+	`hinting-engine' and `no-stem-darkening' properties (only the Adobe
+	engine listens to them).
+	* src/cff/cffgload.c: Include `cf2ft.h'.
+	(cff_decoder_prepare): Initialize `current_subfont'.
+	(cff_build_add_point): Handle Adobe engine which uses 16.16
+	coordinates.
+	(cff_slot_load): Handle FT_LOAD_NO_SCALE and FT_LOAD_NO_HINTING
+	separately.
+	Choose rendering engine based on `hinting_engine' property.
+	* src/cff/cffload.c (cff_font_done): Call finalizer of the Adobe
+	engine.
+	* src/cff/cffobjs.c: Include FT_CFF_DRIVER_H.
+	(cff_driver_init): Set default property values.
+
+	* src/cff/rules.mk (CFF_DRV_SRC, CFF_DRV_H): Add new files.
+
+	* src/cff/cf2*.*: New files, containing the Adobe engine.
+
+2013-04-12  Werner Lemberg  <wl@gnu.org>
+
+	[cff] Minor code administration issues.
+
+	* src/cff/cffgload.c (check_points): Rename to...
+	(cff_check_points): ...this and make it FT_LOCAL.
+	(cff_builder_add_point, cff_builder_add_point1,
+	cff_builder_start_point, cff_builder_close_contour,
+	cff_lookup_glyph_by_stdcharcode, cff_get_glyph_data,
+	cff_free_glyph_data): Make them FT_LOCAL.
+
+	* src/cff/cffgload.h: Updated.
+
+2013-04-12  Werner Lemberg  <wl@gnu.org>
+
+	Add output bitmap checksums.
+
+	Use `FT2_DEBUG=bitmap:3' for tracing.
+
+	* src/base/md5.c, src/base/md5.h: New files, taken from
+
+	  http://openwall.info/wiki/people/solar/software/public-domain-source-code/md5
+
+	* include/freetype/internal/fttrace.h: Add `bitmap'.
+
+	* src/base/ftobjs.c [FT_DEBUG_LEVEL_TRACE]: Include `md5.c'
+
+	(FT_Render_Glyph_Internal) [FT_DEBUG_LEVEL_TRACE]: For tracing,
+	convert resulting bitmap to a uniform format and compute a checksum.
+	Use `bitmap' category for the tracing message.
+
+	* src/base/rules.mk (BASE_H): Updated.
+
+	* docs/LICENSE.TXT: Updated.
+
+2013-04-12  Werner Lemberg  <wl@gnu.org>

+	* src/cff/cffpic.h: Include FT_SERVICE_PROPERTIES_H.
+	(CFF_SERVICE_PROPERTIES_GET): New macro.
+	(CffModulePIC): Add `cff_service_properties'.
+
+2013-04-03  Werner Lemberg  <wl@gnu.org>
+
+	[bdf] Fix Savannah bug #38589.
+
+	* src/bdf/bdflib.c (_bdf_readstream): Thinko.
+
+2013-03-31  Werner Lemberg  <wl@gnu.org>
+
+	* configure: Use egrep, not grep.
+
+	Problem reported Mojca Miklavec <mojca.miklavec.lists@gmail.com>.
+
+2013-03-29  Werner Lemberg  <wl@gnu.org>
+
+	* include/freetype/ftlcdfil.h: Add description of color filtering.
+
+	Based on a contribution from Antti S. Lankila <alankila@bel.fi>
+	(Savannah bug #38607).
+
+2013-03-23  Werner Lemberg  <wl@gnu.org>
+
+	[autofit] Minor.
+
+	* src/autofit/afmodule.c (af_property_set): Typo.
+	(af_autofitter_init, af_autofitter_done): Use cast.
+
+2013-03-21  Werner Lemberg  <wl@gnu.org>
+
+	* configure: Automatically test for `gmake' also.
+
+	Suggested by Mojca Miklavec <mojca.miklavec.lists@gmail.com>.
+
+2013-03-21  Peter Breitenlohner  <peb@mppmu.mpg.de>
+
+	Respect CONFIG_SHELL from the environment.
+
+	Some large packages using FreeType have to use a broken (deficient)
+	/bin/sh.  The configure scripts (as generated by Autoconf) are
+	clever enough to find a better shell and put that one into the
+	environment variable CONFIG_SHELL.  If that environment variable is
+	already set the script skips the test and assumes to be already
+	running under a good shell.
+
+	* builds/unix/detect.mk: Honour CONFIG_SHELL.
+	* builds/unix/unix-def.in (SHELL): Define.
+
+2013-03-21  Werner Lemberg  <wl@gnu.org>
+
+	Fix Savannah patch #7971.
+
+	* configure: Handle MAKE environment variable also.
+
+2013-03-17  Werner Lemberg  <wl@gnu.org>
+
+	Fix Savannah bug #38538.
+
+	* builds/amiga/src/base/ftdebug.c, builds/win32/ftdebug.c,
+	builds/wince/ftdebug.c (FT_Throw): Add function.
+
+2013-03-17  Werner Lemberg  <wl@gnu.org>
+
+	[raster] Remove dead code.
+
+	* src/raster/rastpic.c (ft_raster1_renderer_class_pic_init)
+	src/smooth/ftspic.c (ft_smooth_renderer_class_pic_init): Do it.
+
+2013-03-17  Werner Lemberg  <wl@gnu.org>
+
+	* src/pshinter/pshpic.h (GET_PIC): Use correct container.
+
+2013-03-15  Werner Lemberg  <wl@gnu.org>
+
+	* include/freetype/ftmoderr.h: Fix commit from 2013-03-11.
+
+	The previous version was not backward compatible.  Reported by
+	Behdad.
+
+2013-03-14  Werner Lemberg  <wl@gnu.org>
+
+	*/*: Use FT_ERR_EQ, FT_ERR_NEQ, and FT_ERR where appropriate.
+
+	FT_Err_XXX and friends are no longer directly used in the source
+	code.
+
+2013-03-14  Werner Lemberg  <wl@gnu.org>
+
+	New error management macros.
+
+	* include/freetype/fterrors.h (FT_ERR_XCAT, FT_ERR_CAT): Move to...
+	* include/freetype/fttypes.h: ... this file.
+	(FT_ERR, FT_ERR_EQ, FT_ERR_NEQ, FT_MODERR_EQ, FT_MODERR_NEQ): New
+	macros.
+
+	* include/freetype/freetype.h: Updated.
+
+2013-03-14  Werner Lemberg  <wl@gnu.org>
+
+	*/*: Use FT_Err_Ok only.
+
+	This is a purely mechanical conversion.
+
+2013-03-14  Werner Lemberg  <wl@gnu.org>
+
+	*/*: Use `FT_THROW'.
+
+	This is essentially a mechanical conversion, adding inclusion of
+	`FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for
+	stand-alone compiling modes of the rasterizer modules.
+
+	To convert the remaining occurrences of FT_Err_XXX and friends it is
+	necessary to rewrite the code.  Note, however, that it doesn't harm
+	if some cases are not handled since FT_THROW is a no-op.
+
+2013-03-13  Werner Lemberg  <wl@gnu.org>
+
+	Introduce `FT_THROW' macro.
+
+	The idea is to replace code like
+
+	  return FT_Err_Foo_Bar;
+
+	or
+
+	  return CFF_Err_Foo_Bar;
+
+	with
+
+	  return FT_THROW( Foo_Bar );
+
+	The FT_THROW macro has two functions:
+
+	  . It hides the module specific prefix.
+
+	  . In debug mode, it calls the empty function `FT_Throw' which can
+	    be thus used to set a breakpoint.
+
+	* include/freetype/internal/ftdebug.h (FT_THROW): New macro.
+	(FT_Throw): New prototype.
+	* src/base/ftdebug.c (FT_Throw): New function.
+
+2013-03-12  Werner Lemberg  <wl@gnu.org>
+
+	Remove `FT_KEEP_ERR_PREFIX'.
+
+	The idea is to always have FT_ERR_PREFIX available internally.
+
+	* include/freetype/fterrors.h: Use FT2_BUILD_LIBRARY to guard
+	undefinition of FT_ERR_PREFIX
+
+	* src/gxvalid/gxverror.h, src/otvalid/otverror.h,
+	src/sfnt/sferrors.h: Updated.
+
+2013-03-11  Werner Lemberg  <wl@gnu.org>
+
+	[gxvalid] Fix module error.
+
+	* src/gxvalid/gxverror.h (FT_ERR_BASE): Define as
+	FT_Mod_Err_GXvalid.
+	* include/freetype/ftmoderr.h: Add module error for `GXvalid'.
+
+2013-03-11  Werner Lemberg  <wl@gnu.org>
+
+	Always use module related error codes.
+
+	* src/cff/cffobjs.c (cff_face_init), src/type1/t1objs.c
+	(T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Use
+	`FT_ERROR_BASE'.
+
+	* src/type1/t1load.c (parse_encoding): Use
+	T1_Err_Unknown_File_Format.
+
+2013-03-08  Werner Lemberg  <wl@gnu.org>
+
+	[cff] Set `linear{Hori,Vert}Advance' for embedded bitmaps also.
+
+	Problem reported by Khaled Hosny <khaledhosny@eglug.org>.
+
+	* src/cff/cffgload.c (cff_slot_load): Implement it.
+
+2013-02-23  Alexei Podtelezhnikov  <apodtele@gmail.com>
+
+	[base] Fix commit ab02d9e8.
+
+	* src/base/ftbbox.c (BBox_Cubic_Check): Change scaling to msb of 22.
+
+2013-02-19  Alexei Podtelezhnikov  <apodtele@gmail.com>
+
+	[base] New bisecting BBox_Cubic_Check (disabled).
+
+	* src/base/ftbbox.c (BBox_Cubic_Check): New bisecting algorithm
+	for extremum search built around simple condition that defines
+	which half contains the extremum.
+
+2013-02-18  Alexei Podtelezhnikov  <apodtele@gmail.com>
+
+	[tools] Update BBox testing tool.
+
+	* src/tools/test_bbox.c: Add another cubic outline with exact BBox.
+	(REPEAT): Increase the number of benchmarking cycles.
+	(profile_outline): Tweak output formatting.
+
+2013-02-02  Werner Lemberg  <wl@gnu.org>
+
+	Fix Savannah bug #38235.
+
+	* builds/unix/configure.raw: Don't generate `freetype-config' and
+	`freetype.pc'.
+
+	* builds/unix/unix-def.in (FT2_EXTRA_LIBS, LIBBZ2, LIBZ,
+	build_libtool_libs, ft_version): New variables to be substituted.
+	(freetype-config, freetype.pc): New rules to generate those files.
+
+	* builds/unix/freetype-config.in: Remove code for handling `rpath'.
+	The use of $rpath has been accidentally removed in a patch from
+	2009-12-22, and apparently noone has missed it since.
+	Use `%' instead of `@' as a variable substitution marker.
+	Use quotes.
+
+	* builds/unix/freetype.in: Use `%' instead of `@' as a variable
+	substitution marker.
+	Use quotes.
+
+2013-02-07  Werner Lemberg  <wl@gnu.org>
+
+	* src/truetype/ttobjs.c (tt_size_run_prep): Reset more GS variables.
+
+	BTW, Greg agrees that the OpenType specification is missing the list
+	of GS variables which will always be reset to the default values
+	after the `prep' table has been executed.
+
+2013-02-06  Werner Lemberg  <wl@gnu.org>
+
+	* src/truetype/ttobjs.c (tt_size_run_prep): Reset reference points.
+
+	Up to now, we simply took a snapshot of the Graphics State after the
+	`prep' table has been executed, and right before a glyph's bytecode
+	was run it got reloaded.  However, as Greg Hitchcock has told us in
+	private communication, reference points get reset to zero in the MS
+	rasterizer and we follow in due course.  While reasonable, this is
+	undocumented behaviour.
+
+	Most notably, this fixes the rendering of Arial's `x' glyph in
+	subpixel hinting mode.
+
+2013-02-05  Werner Lemberg  <wl@gnu.org>
+
+	[truetype] A better fix for Savannah bug #38211.

+
+	[truetype] Improve subpixel code.
+
+	This patches fixes many issues with the ttsubpix implementation.
+
+	1. Data tables are defined, instead of declared, in the header, and
+	   thus copied into each source file that includes it.
+
+	2. These tables were defined as global, mutable, visible variables,
+	   and thus costing private RAM to every process that loads the
+	   library (> 50 KB / process, this is huge!).
+
+	   Additionally, this also made the library export the symbols
+	   completely needlessly.
+
+	3. Missing `sph_' and `SPH_' prefixes to some of the definitions.
+
+	Note that this doesn't try to fix the incredibly inefficient storage
+	format for the data tables used by the code.  This one will require
+	another pass in the future.

+
+	[truetype] Improve accuracy of normalization of short vectors.
+
+	Unit vector components are stored as 2.14 fixed-point numbers. In

+
+	[base] Improve trigonometric core.
+
+	FreeType used to rely on a 24-step iteration CORDIC algorithm to
+	calculate trigonometric functions and rotate vectors. It turns out
+	that once the vector is in the right half-plane, the initial rotation
+	by 63 degrees is not necessary. The algorithm is perfectly capable
+	to converge to any angle starting from the second 45 degree rotation.
+	This patch removes the first rotation and makes it a 23-step CORDIC
+	algorithm.

+
+	[truetype] Scale F_dot_P down.
+
+	The dot product between freeVector and projVector or cosine of
+	the angle between these FT_F2Dot14 unit vectors used to be scaled up
+	by 4 and routinely occupied 32 bits in an FT_Long field F_dot_P.
+	This patch scales the value down by 2^14 instead, which simplifies
+	its use throughout the bytecode interpreter.
+
+	This does not lead to the loss of precision because the lower bits
+	are unreliable anyway. Consider two unit vectors (1,0) and (.6,.8)
+	for which the true value of F_dot_P is .6 * 0x40000000 = 0x26666666.
+	These vectors are stored as (0x4000,0) and (0x2666,0x3333) after
+	rounding and F_dot_P is assigned 0x26660000. The lower bits were
+	already lost while rounding the unit vector components.
+
+	Besides code simplification, this change can lead to better
+	performance when FT_MulDiv with the scaled-down F_dot_P is less
+	likely to use the costly 64-bit path. We are not changing the type
+	of F_dot_P to FT_F2Dot14 at this point.
+
+	* src/truetype/ttinterp.c (Compute_Funcs): Scale F_dot_P down by 14
+	bits and modify its use accordingly.
+	(Direct_Move, Direct_Move_Orig, Compute_Point_Displacement): Modify
+	the use of F_dot_P field.
+	* src/truetype/ttobjs.c (tt_size_run_fpgm): Change arbitrary
+	assignment of F_dot_P to its theoretical maximum in case we decide
+	to scale back its type later.

+2012-06-18  Infinality  <infinality@infinality.net>
+
+	[truetype] Support subpixel hinting.
+
+	This is the large, famous `Infinality' patch to support ClearType
+	bytecode which has been available from
+	http://www.infinality.net/blog/ for some time, and which has been
+	refined over the last years.  While still experimental, it is now
+	mature enough to be included directly into FreeType.
+
+	Most of the code is based on the ClearType whitepaper written by
+	Greg Hitchcock
+
+	  https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx
+
+	which gives a detailed overview of the necessary changes to the
+	Microsoft rasterizer so that older fonts are supported.  However, a
+	lot of details are still missing, and this patches provides a
+	framework to easily handle rendering issues down to the glyph level
+	of certain fonts.
+
+	Note that ClearType support is not completely implemented!  In
+	particular, full support for the options `compatible_widths',
+	`symmetrical_smoothing, and `bgr' (via the GETINFO bytecode
+	instruction) is missing.
+
+	* src/truetype/ttsubpix.c: New file, providing code to handle
+	`tweaks', this is, rules for certain glyphs in certain fonts
+	(including wildcards) which need a special treatment.
+
+	* src/truetype/ttsubpix.h: New file, holding the tweaking rules.
+
+	* include/freetype/config/ftoption.h, src/devel/ftoption.h

+
+	[type1] Fix Savannah bug #35833.
+
+	Based on the patch given in the bug report.
+
+	* src/type1/t1load.c (IS_INCREMENTAL): New macro.
+	(read_binary_data): Add parameter `incremental'.
+	Update all callers using `IS_INCREMENTAL'.
+

+
+	[autofit] Return correct linear advance width values.
+
+	This was quite a subtle bug which accidentally showed up with glyph
+	`afii10023' of arial.ttf (version 2.76).  This glyph is a composite;
+	the first component, `E', has an advance width of 1366 font units,
+	while the advance width of the composite itself (which looks like
+	uppercase `E' with dieresis) is 1367 font units.  I think this is
+	actually a bug in the font itself, because there is no reason that
+	this glyph has not the same width as uppercase `E' without the
+	dieresis.  Anyway, it helped identify this problem.
+
+	Using the TrueType hinter, the correct value (1367) of `afii10023'
+	was returned, but the autohinter mysteriously returned 1366.
+
+	Digging in the code showed that the autohinter recursively calls
+	FT_Load_Glyph to load the glyph, adding the FT_LOAD_NO_SCALE load
+	flag.  However, the `linearHoriAdvance' field is still returned as a
+	scaled value.  To avoid scaling twice, the old code in autofit reset
+	`linearHoriAdvance', using the `horiAdvance' field.  This seemed to
+	work since FT_LOAD_NO_SCALE was in use, but it failed actually,
+	because `horiAdvance' is defined as the distance of the first
+	subglyph's phantom points, which in turn are initialized using the
+	advance width of the first subglyph.  And as the given example
+	shows, these widths can differ.
+
+	* src/autofit/afloader.c (af_loader_load_g): Temporarily set
+	FT_LOAD_LINEAR_DESIGN while calling FT_Load_Glyph to get unscaled
+	values for the linear advance widths.

+
+	[truetype] Fix SSW instruction.
+
+	* src/truetype/ttinterp.c (DO_SSW): SSW *does* use font units.  For

+	this instruction.

+
+	Fix redundant declaration warning in PIC mode.
+
+	Originally FT_DEFINE_{DRIVER,MODULE,RENDERER}() macros were
+	designed to declare xxx_pic_{free,init} by themselves.
+	Because these macros are used at the end of the module
+	interface (e.g. ttdriver.c) and the wrapper source to build
+	a module as a single object (e.g. truetype.c) includes
+	the PIC file (e.g. ttpic.c) before the module interface,
+	these macros are expanded AFTER xxx_pic_{free,init} body
+	when the modules are built as single object.
+	The declaration after the implementation causes the redundant
+	declaration warnings, so the declarations are moved to module
+	PIC headers (e.g. ttpic.h).  Separating to other header files
+	are needed for multi build.

+
+	[base] Fix a dereference of uninitialized variable in PIC mode.
+
+	* src/base/ftglyph.c (FT_Glyph_To_Bitmap): `glyph' must be
+	set before dereferring to obtain `library'.  The initialization
+	of `clazz', `glyph', `library' and NULL pointer check are
+	reordered to minimize PIC conditionals.
+
+2012-01-14  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	[base] Insert explicit cast for GCC 4.6 in PIC mode.
+
+	* src/base/ftinit.c (FT_Add_Default_Modules): Under PIC
+	configuration, FT_DEFAULT_MODULES_GET returns
+	FT_Module_Class** pointer, GCC 4.6 warns that
+	const FT_Module_Class* const* variable is warned as
+	inappropriate to store it.  To calm it, explicit cast is

+	pointer dereference in FT_DEFAULT_MODULES_GET.
+
+2012-01-13  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	Fix PIC build broken by d9145241fe378104ba4c12a42534549faacc92e6.
+
+	Under PIC configuration, FT_{CFF,PSCMAPS,SFNT,TT}_SERVICES_GET
+	take no arguments but derefer the variable named `library'
+	internally.

+	set it if non-NULL driver is passed.
+	* src/truetype/ttdriver.c (tt_get_interface): Ditto.
+
+	* src/sfnt/sfdriver.c (sfnt_get_interface): Declare `library'

+
+2011-12-10  Werner Lemberg  <wl@gnu.org>

+
+2011-12-08  Werner Lemberg  <wl@gnu.org>
+
+	Fix serious scaling bug in `FT_Get_Advances'.
+
+	* src/base/ftadvanc.c (FT_Get_Advances): Advance values returned by
+	`FT_Load_Glyph' must be simply multiplied by 1024.
+
+2011-12-08  Werner Lemberg  <wl@gnu.org>
+
+	* src/bdf/bdflib.c (_bdf_parse_start): Drop redundant error tracing.
+
+2011-12-02  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	[mac] Unify DARWIN_NO_CARBON with FT_MACINTOSH.
+
+	Originally FT_MACINTOSH was a pure auto macro and DARWIN_NO_CARBON
+	was a configurable macro to disable Carbon-dependent code.  Because
+	now configure script sets DARWIN_NO_CARBON by default and disables
+	Darwin & Carbon-dependent codes, these macros can be unified.
+	FT_MACINTOSH (undefined by default) is kept and DARWIN_NO_CARBON
+	(defined by default) is removed, because DARWIN_NO_CARBON violates
+	FT_XXX naming convention of public macros, and a macro configured by
+	default is not portable for the building without configure (e.g.
+	make devel).
+
+	* builds/unix/configure.raw: Define FT_MACINTOSH if Carbon-based
+	old Mac font support is requested and Carbon is available.
+	* builds/unix/ftconfig.in: Undefine FT_MACINTOSH when the support
+	for Mac OS X without Carbon (e.g.  Mac OS X 10.4 for ppc64) is
+	requested.
+	* include/freetype/config/ftconfig.in: Ditto.

+
+	* src/base/ftmac.c: Compile the body if FT_MACINTOSH is defined
+	(same with TT_USE_BYTECODE_INTERPRETER in ttinterp.c).
+	* builds/mac/ftmac.c: Ditto.
+
+	* builds/mac/FreeType.m68k_cfm.make.txt: Define FT_MACINTOSH.

+2011-11-30  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	Fix Savannah bug #34728 (`make devel' on Mac OS X).
+
+	* builds/toplevel.mk: Check `/dev/null' to identify the Unix-
+	like systems without `init' nor `hurd' (e.g. Mac OS X >= 10.4).
+	* builds/unix/detect.mk: Ditto.
+

+
+	[apinames] Fix the overflow of signed integer hash.
+
+	* src/tools/apinames.c (names_add): Change the type of `h' from
+	int to unsigned int, to prevent undefined behaviour in the
+	overflow of signed integers (overflow of unsigned int is defined
+	to be wrap around).  Found by clang test suggested by Sean
+	McBride.
+
+2011-11-30  Werner Lemberg  <wl@gnu.org>

+
+2011-11-27  Werner Lemberg  <wl@gnu.org>
+
+	[bdf] Fix Savannah bug #34896.
+
+	ENCODING now covers the whole Unicode range.
+
+	Note, however, that this change is quite expensive since it
+	increases the size of three arrays by almost 400kByte in total.  The
+	right fix is to replace the logic with something smarter.
+	Additionally, there exist very old BDFs for three-byte CCCII
+	encoding which exceeds the range of Unicode (another reason to have
+	a smarter logic).
+
+	* src/bdf/bdf.h (bdf_font_t): Increase size of `nmod' and `umod'
+	arrays.
+	* src/bdf/bdflib.c (bdf_parse_t): Increase size of `have' array.
+
+2011-11-27  Werner Lemberg  <wl@gnu.org>

+
+	[smooth] Slightly optimize conic and cubic flatteners.
+
+	* src/smooth/ftgrays.c (gray_render_conic, gray_render_cubic): Move
+	out some code from the main loop to speed it up.
+
+2011-09-11  Tomas Hoger  <thoger@redhat.com>
+
+	Slightly improve LZW_CLEAR handling.
+
+	* src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_CODE>:
+	Ensure that subsequent (modulo garbage byte(s)) LZW_CLEAR codes are
+	handled as clear codes.  This also re-sets old_code and old_char to
+	predictable values, which is a little better than using `random'
+	ones if the code following LZW_CLEAR is invalid.
+
+2011-09-11  Tomas Hoger  <thoger@redhat.com>
+
+	Add explicit LZW decompression stack size limit.
+
+	Stack larger than 1<<LZW_MAX_BITS is never needed if prefix table is
+	constructed correctly.  It's even less than that, see e.g.
+	libarchive code comment for a better size upper bound:
+
+	  http://code.google.com/p/libarchive/source/browse/trunk/libarchive/archive_read_support_filter_compress.c?r=3635#121
+
+	This patch adds explicit stack size limit, enforced when stack is
+	realloced.
+
+	An alternative is to ensure that code < state->prefix[code - 256]
+	when traversing prefix table.  Such check is less efficient and
+	should not be required if prefix table is constructed correctly in
+	the first place.
+
+	* src/lzw/ftzopen.c (ft_lzwstate_stack_grow): Implement it.
+
+2011-09-11  Tomas Hoger  <thoger@redhat.com>
+
+	Protect against loops in the prefix table.
+
+	LZW decompressor did not sufficiently check codes read from the
+	input LZW stream.  A specially-crafted or corrupted input could
+	create a loop in the prefix table, which leads to memory usage
+	spikes, as there's no decompression stack size limit.
+
+	* src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_START>: First

+
+	[ftstroke] Major revision.
+
+	The main problems
+	-----------------
+
+	  o If FT_STROKER_LINEJOIN_BEVEL was specified, unlimited miter
+	    joins (not bevel joins) were generated.  Indeed, the meanings of
+	    `miter' and `bevel' were incorrectly reversed (consistently) in
+	    both the code and comments.
+
+	  o The way bevel joins were constructed (whether specified
+	    explicitly, or created as a result of exceeding the miter limit)
+	    did not match what is required for stroked text in PostScript or
+	    PDF.
+
+	The main fixes
+	--------------
+
+	  o The behaviour of FT_STROKER_LINEJOIN_BEVEL has been corrected.
+
+	  o A new line join style, FT_STROKER_LINEJOIN_MITER_FIXED, has been
+	    introduced to support PostScript and PDF miter joins.
+
+	  o FT_STROKER_LINEJOIN_MITER_VARIABLE has been introduced as an
+	    alias for FT_STROKER_LINEJOIN_MITER.
+
+	Additionally, a variety of stroking errors have been fixed.  These
+	would cause various artifacts (including points `at infinity'),
+	especially when stroking poor quality fonts.
+
+	See
+
+	  https://lists.gnu.org/archive/html/freetype-devel/2011-07/msg00001.html
+
+	for example documents.  The FreeType stroker now produces results
+	very similar to that produced by GhostScript and Distiller for these
+	fonts.
+
+	Other problems
+	--------------
+
+	The following problems have been resolved:
+
+	  o Inside corners could be generated incorrectly.  Intersecting the
+	    inside corner could cause a missing triangular area and other
+	    effects.
+
+	    The intersection point can only be used if the join is between
+	    two lines and both lines are long enough.  The `optimization'
+	    condition in `ft_stroker_inside' has been corrected; this
+	    requires the line length to be passed into various functions and
+	    stored in `FT_StrokerRec'.
+
+	  o Incorrect cubic curves could be generated.  The angle
+	    calculations in `FT_Stroker_CubicTo' have been corrected to
+	    handle the case of the curve crossing the +/-PI direction.
+
+	  o If the border radius was greater than the radius of curvature of
+	    a curve, then the negative sector would end up outside (not
+	    inside) the border.  This situation is now recognized and the
+	    negative sector is circumnavigated in the opposite direction.
+	    (If round line joins are being used, this code is disabled
+	    because the line join will always cover the negative sector.)
+
+	  o When a curve is split, the arcs may not join smoothly (especially
+	    if the curve turns sharply back on itself).  Changes in
+	    direction between adjacent arcs were not handled.  A round
+	    corner is now added if the deviation from one arc to the next is
+	    greater than a suitable threshold.
+
+	  o The current direction wasn't retained if a the outline contained
+	    a zero length lineto or a curve that was determined to be
+	    `basically a point'.  This could cause a spurious join to be
+	    added.
+
+	  o Cubics with close control points could be mishandled.  All eight
+	    cases are now distinguished correctly.
+
+	Other improvements
+	------------------
+
+	o Borders for cubic curves could be too `flat'.
+	  FT_SMALL_CUBIC_THRESHOLD has been reduced a little to prevent
+	  this.
+
+	o The handling and use of movable points has been simplified a
+	  little.
+
+	o Various values are now computed only if the results are actually
+	  needed.
+
+	o The directions of the outer and inner borders have been swapped,
+	  as recommended by Graham Asher.

+
+	[cache] Fix Savannah bug #31923, patch drafted by Harsha.
+
+	When a node comparator changes the cached nodes during the
+	search of a node matching with queried properties, the
+	pointers obtained before the function should be updated to
+	prevent the dereference to freed or reallocated nodes.
+	To minimize the rescan of the linked list, the update is
+	executed when the comparator notifies the change of cached
+	nodes. This change depends previous change:
+	38b272ffbbdaae276d636aec4ef84af407d16181
+
+	* src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Rescan the
+	top node if the cached nodes are changed.
+	* src/cache/ftccache.c (FTC_Cache_Lookup): Ditto.
+
+2011-01-09  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	[cache] Notice if a cache query induced the node list change.
+
+	Some node comparators (comparing the cache node contents and the
+	properties specified by the query) can flush the cache node to
+	prevent the cache inflation.  The change may invalidate the pointers
+	to the node obtained before the node comparison, so it should be
+	noticed to the caller.  The problem caused by the cache node
+	changing is reported by Harsha, see Savannah bug #31923.
+
+	* src/cache/ftccache.h (FTC_Node_CompareFunc): Add new argument
+	`FT_Bool* list_changed' to indicate the change of the cached nodes
+	to the caller.
+	(FTC_CACHE_LOOKUP_CMP): Watch the change of the cached nodes by
+	`_list_changed'.
+	(FTC_CACHE_TRYLOOP_END): Take new macro argument `_list_changed'
+	and update it when `FTC_Manager_FlushN' flushes any nodes.
+
+	* src/cache/ftccback.h (ftc_snode_compare): Updated to fit with new
+	FTC_Node_CompareFunc type.
+	(ftc_gnode_compare): Ditto.
+
+	* src/cache/ftcbasic.c: Include FT_INTERNAL_OBJECTS_H to use

+	* src/cache/ftccmap.c: Include FT_INTERNAL_OBJECTS_H to use
+	TRUE/FALSE macros.
+	(ftc_cmap_node_compare): New argument `FT_Bool* list_changed' to

+	passed to `ftc_gnode_compare'.
+	* src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto.
+
+	* src/cache/ftcsbits.c (ftc_snode_compare): New argument `FT_Bool*
+	list_changed' to indicate the change of the cache nodes, anyway.  It
+	is updated by `FTC_CACHE_TRYLOOP'.
+	(FTC_SNode_Compare): New argument `FT_Bool* list_changed' to be
+	passed to `ftc_snode_compare'.
+	* src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto.
+
+2011-01-09  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	[cache] Fit `FTC_GNode_Compare' to `FTC_Node_CompareFunc'.
+
+	* src/cache/ftcglyph.h (FTC_GNode_Compare): Add the 3rd
+	argument `FTC_Cache  cache' to fit FTC_Node_CompareFunc
+	prototype.
+	* src/cache/ftcglyph.c (FTC_GNode_Compare): Ditto. Anyway,
+	`cache' is not used by its child `ftc_gnode_compare'.
+
+2011-01-09  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	[cache] Deduplicate the code to get the top node by a hash.
+
+	There are several duplicated code fragments getting the top node
+	from a cache by a given hash, like:
+
+	    idx = hash & cache->mask;
+	    if ( idx < cache->p )
+	      idx = hash & ( cache->mask * 2 + 1 );
+	    pnode = cache->buckets + idx;
+
+	To remove duplication, a cpp-macro to do same work
+	`FTC_NODE__TOP_FOR_HASH' is introduced.  For non-inlined
+	configuration, non-`ftc_get_top_node_for_hash' is also introduced.
+
+	* src/cache/ftccache.h (FTC_NODE__TOP_FOR_HASH): Declare
+	and implement inlined version.
+	(FTC_CACHE_LOOKUP_CMP): Use `FTC_NODE__TOP_FOR_HASH'.
+	* src/cache/ftccache.c (ftc_get_top_node_for_hash): Non-inlined

+
+2011-01-09  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	[cache] inline-specific functions are conditionalized.
+
+	* src/cache/ftcglyph.c (FTC_GNode_Compare): Conditionalized for
+	inlined configuration.  This function is a thin wrapper of
+	`ftc_gnode_compare' for inlined `FTC_CACHE_LOOKUP_CMP' (see
+	`nodecmp' argument).  Under non-inlined configuration,
+	`ftc_gnode_compare' is invoked by `FTC_Cache_Lookup', via
+	`FTC_Cache->clazz.node_compare'.
+
+	* src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto.
+	* src/cache/ftcsbits.c (FTC_SNode_Compare): Ditto, for
+	`ftc_snode_compare'.
+	* src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto.
+
+2011-01-09  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	[cache] Correct a type mismatch under non-inlined config.
+
+	* src/cache/ftcglyph.h (FTC_GCACHE_LOOKUP_CMP): `FTC_GCache_Lookup'

+	`FTC_CACHE_LOOKUP_CMP'.

+
+	Apply Savannah patch #7422.
+
+	If we encounter a space in a string then the sbit buffer is NULL,
+	height and width are 0s.  So the check in ftc_snode_compare will
+	always pass for spaces (comparison with 255).  Here the comments
+	above the condition are proper but the implementation is not.  When
+	we create an snode I think it is the proper way to initialize the
+	width to 255 and then put a check for being equal to 255 in snode
+	compare function.
+
+	* src/cache/ftcsbits.c (FTC_SNode_New): Initialize sbit widths with
+	value 255.
+	(ftc_snode_compare): Fix condition.

+
+	[cache] Change the hash types to FT_PtrDist.
+
+	On LLP64 platforms (e.g. Win64), FT_ULong (32-bit)
+	variables are inappropriate to calculate hash values

+	are extended from FT_ULong to FT_PtrDist and new
+	hashing macro functions are introduced.  The hash
+	values on 16-bit memory platforms are changed, but
+	ILP32 and LP64 are not changed.  The hash value in
+	the cache subsystem is not reverted to the memory
+	address, so using signed type FT_PtrDist is safe.
+
+	* src/cache/ftccache.h (_FTC_FACE_ID_HASH): New hash

+
+	When a resource fork access rule by Darwin VFS could open the

+
+	* src/base/ftobjs.c (load_face_in_embedded_rfork):
+	When `FT_Stream_New' returns FT_Err_Cannot_Open_Stream, it

+	Also there is a case that the resource fork is not zero-sized,
+	but no supported font exists in it.  If a rule by Darwin VFS
+	falls into such cases, there is no need to try other Darwin VFS
+	rules anymore.  Such cases are marked by vfs_rfork_has_no_font.
+	If it is TRUE, the Darwin VFS rules are skipped.

+
+	MacOS X/Darwin kernel supports a few tricky methods to access

+	But if a method could open a resource fork but no font is found,
+	there is no need to try other methods older than tested method.
+	To determine whether the rule index is for Darwin VFS, a local
+	function `ftrfork.c::raccess_rule_by_darwin_vfs' is introduced.
+	To use this function in ftobjs.c etc but it should be inlined,
+	it is exposed by ftbase.h.

+	intra module functions.

+
+	Additional fix for Savannah bug #30306.
+

+2010-05-10  Ken Sharp  <ken.sharp@artifex.com>
+
+	[psaux] Fix Savannah bug #29846.
+
+	Previously we discovered fonts which used `setcurrentpoint' to set
+	the initial point of a contour to 0,0.  This caused FreeType to
+	raise an error, because the `setcurrentpoint' operator is only
+	supposed to be used with the results from an OtherSubr subroutine.
+
+	This was fixed by simply ignoring the error and carrying on.
+
+	Now we have found a font which uses setcurrentpoint to actually
+	establish a non-zero point for a contour during the course of a
+	glyph program.  FWIW, these files may be produced by an application
+	called `Intaglio' on the Mac, when converting TrueType fonts to
+	Type 1.
+
+	The fix allows the new invalid behaviour, the old invalid behaviour
+	and real proper usage of the operator to work the same way as Adobe
+	interpreters apparently do.
+
+	* src/psaux/t1decode.c (t1_decoder_parse_charstrings): Make
+	`setcurrentpoint' use the top two elements of the stack to establish
+	unconditionally the current x and y coordinates.
+
+	Make the `flex' subroutine handling (OtherSubr 0) put the current
+	x,y coordinates onto the stack, instead of two dummy uninitialised
+	values.
+
+2010-04-14  Ken Sharp  <ken.sharp@artifex.com>
+
+	[psaux] Fix Savannah bug #29444.
+
+	* src/psaux/psobjs.c (t1_builder_start_point): Accept (invalid)
+	`lineto' immediately after `hsbw', in accordance with Acrobat, GS,
+	and others.
+
+2010-04-14  Michał Cichoń  <thedmd@artifexmundi.com>
+
+	[psaux] Fix Savannah bug #27999.

+	however.
+
+2010-04-05  Werner Lemberg  <wl@gnu.org>
+
+	Add new function `FT_Library_SetLcdFilterWeights'.

+	[otvalid] Fix a naming convention conflicting with ftvalid.
+
+	Some prototypes in ftvalid.h use `valid' for the variables

+
+	Some macros in otvcommn.h assume the exist of the variable
+	`valid' typed as OTV_Validator in the caller.
+
+	Mixing these two conventions cause invalid pointer conversion
+	and unexpected SEGV in longjmp.  To prevent it, all variables
+	typed as OTV_Validator are renamed to `otvalid'.

+	Work around `features' of X11's `pcfWriteFont' and `pcfReadFont'

+	[autofit] Better fix for conversion specifiers in debug messages.
+
+	Using `%ld' for pointer differences causes warnings on 32bit

+	however, this is missing on some important platforms.
+
+	This patch improves the change from 2014-11-28.

+
+	Before this patch, the suggested order of entries stopped at the
+	first empty line.
+
+	Obviously, nobody noticed that this problem caused a much reduced

+
+2014-11-27  Werner Lemberg  <wl@gnu.org>
+
+	* src/tools/docmaker/tohtml.py: Remove remaining `width' attributes.
+
+	For `Index' and `TOC' links, we now simply use the `text-align' CSS
+	property of `<td>' to enforce flush-left and flush-right,
+	eliminating the hack with an empty, full-width `<td>' element
+	inbetween.
+
+	The change also enforces the same (smaller) size for all index and

+
+	[Savannah bug #43682] Add/remove `void' casts to some functions.

+

+
+	Don't cast cmap init function pointers to an incompatible type.
+
+	Without this patch, the number of parameters between declaration and
+	the real signature differs.  Calling such a function results in
+	undefined behavior.
+
+	  ISO/IEC 9899:TC3 (Committee Draft September 7, 2007)
+	    6.5.2.2 Function calls
+	      9 If the function is defined with a type that is not
+	        compatible with the type (of the expression) pointed to by
+	        the expression that denotes the called function, the
+	        behavior is undefined.
+
+	On certain platforms (c -> js with emscripten) this causes
+	termination of execution or invalid calls because in the emscripten
+	implementation, function pointers of different types are stored in
+	different pointer arrays.  Incorrect pointer type here results in
+	indexing of an incorrect array.

+	Avoid compiler warnings on x86-64 for `FT_MulFix'.
+
+	`FT_MulFix' takes `FT_Long' parameters as defined in `freetype.h',

+
+	Before this patch, it was impossible to ever call DELTAP[123] in

+	only worked if in `compatibility mode'.  However, compatibility mode
+	essentially disables SHPIX, completely ruining hinting of

+
+	[autofit] Fix Savannah bug #42148.
+
+	The adaptation of the cjk auto-hinter module to blue stringsets in
+	2013-08-25 had three severe bugs.  Mea culpa.
+
+	1. Contrary to the latin auto-hinter, characters for reference and
+	   overshoot values of a blue zone are specified separately.  Due to
+	   the screwed-up change it didn't work at all.
+
+	2. A boolean comparison was erroneously replaced with a cast,
+	   causing invalid results with the `^' operator later on.  The
+	   visual artifact caused by this problem is the topic of the bug
+	   report.
+
+	3. Two flag values were inverted, causing incorrect assignment of
+	   reference and overshoot values.
+
+	* src/autofit/afblue.dat: Fix CJK bluestrings, introducing a new
+	syntax to have both reference and overshoot characters in a single
+	string.  This is error #1.
+	Add extensive comments.
+
+	* src/autofit/afblue.hin (AF_BLUE_PROPERTY_CJK_FILL): Removed, no
+	longer used.
+	(AF_BLUE_PROPERTY_CJK_TOP, AF_BLUE_PROPERTY_CJK_HORIZ): Fix values.
+	This is error #3.
+
+	* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
+
+	* src/autofit/afcjk.c (af_cjk_metrics_init_blues): Correct error #1.
+	Use character `|' to separate characters for reference and overshoot
+	values.
+	Improve tracing messages, synchronizing them with the latin
+	auto-hinter.
+	(af_cjk_hints_compute_blue_edges): Fix value of `is_top_right_blue'.
+	This is error #2.
+	(af_cjk_align_linked_edge): Add tracing message.
+
+	* src/autofit/afcjk.h (AF_CJK_IS_FILLED_BLUE): Removed, no longer
+	used.
+
+2014-04-17  Werner Lemberg  <wl@gnu.org>
+
+	[autofit] More coverage fixes for complex scripts.
+
+	* src/autofit/hbshim.c (af_get_coverage): Merge input glyph coverage

+	handled properly.
+	Don't check blue zone characters for default coverage.
+

+
+	Make `FT_Get_SubGlyph_Info' actually work.

+

+
+	[smooth] Fix stand-alone compilation.
+

+
+2014-04-12  Werner Lemberg  <wl@gnu.org>
+
+	[autofit] Redesign the recognition algorithm of strong points.
+
+	In particular, local extrema without horizontal or vertical segments
+	are better recognized:
+
+	  + A                + D
+	   \                /
+	    \              /
+	     \            /
+	      \          /
+	       \        + C
+	        \    /
+	       B +/
+
+	If the distances AB and CD are large, point B wasn't previously
+	detected as an extremum since the `ft_corner_is_flat' function
+	`swallowed' BC regardless of its direction, tagging point B as weak.
+	The next iteration started at B and made `ft_corner_is_flat' swallow
+	point C, tagging it as weak also, et voilà.
+
+	To improve that, another pass gets now performed before calling
+	`ft_corner_is_flat' to improve the `topology' of an outline: A
+	sequence of non-horizontal or non-vertical vectors that point into
+	the same quadrant are handled as a single, large vector.
+
+	Additionally, distances of near points are now accumulated, which
+	makes the auto-hinter handle them as if they were prepended to the
+	next non-near vector.
+
+	This generally improves the auto-hinter's rendering results.
+
+	* src/autofit/afhints.c (af_glyph_hints_reload): Implement it.
+
+	* src/autofit/afhints.h (AF_FLAGS): Remove no longer used flag
+	`AF_FLAG_NEAR'.
+
+2014-04-05  Werner Lemberg  <wl@gnu.org>
+
+	[autofit] Improve scoring algorithm for identifying stems.
+
+	Problem reported by Karsten Lücke <karsten.luecke@kltf.de>.
+
+	The new algorithm takes care of the width of stems: If the distance
+	between two segments is larger than the largest stem width, the
+	demerits quickly increase for larger distances.  This improves
+	hinting of slanted fonts (especially if the inner parts of serifs
+	have non-horizontal `shoulders'), avoiding false stem links.
+
+	* src/autofit/aflatin.c (af_latin_hints_link_segments): Use largest
+	stem width (if available) to compute better demerits for distances
+	between stems.
+	(af_latin_hints_detect_features): Pass stem width array and array
+	size.
+	(af_latin_metrics_init_widths): Updated to use original algorithm.

+2014-03-01  Werner Lemberg  <wl@gnu.org>
+
+	Avoid `long long' warnings with older gcc compilers.
+	Problem reported by Hin-Tak Leung <htl10@users.sourceforge.net>.
+
+	* builds/unix/configure.raw: Don't use gcc's `-pedantic' flag for
+	versions < 4.6.  This is especially needed for Max OS X since this
+	OS runs a gcc variant (or emulation) based on version 4.2.1.
+
+2014-03-01  Werner Lemberg  <wl@gnu.org>
+
+	* docs/INSTALL.CROSS: Revised and updated.
+
+2014-03-01  Werner Lemberg  <wl@gnu.org>
+
+	Make `make clean' remove `freetype2.pc'.

+
+	* builds/unix/unix-def.in (DISTCLEAN): Move `freetype2.pc' to ...

+
+2014-03-01  Werner Lemberg  <wl@gnu.org>
+

+
+2014-02-28  Dave Arnold  <darnold@adobe.com>
+
+	[cff] Fix Savannah bug #41697, part 2.
+
+	* src/cff/cf2ft.c (cf2_initLocalRegionBuffer,
+	cf2_initGlobalRegionBuffer): It is possible for a charstring to call
+	a subroutine if no subroutines exist.  This is an error but should
+	not trigger an assert.  Split the assert to account for this.
+
+2014-02-28  Dave Arnold  <darnold@adobe.com>
+
+	[cff] Fix Savannah bug #41697, part 1.
+
+	* src/cff/cf2hints.c (cf2_hintmap_build): Return when `hintMask' is

+
+2014-02-26  Werner Lemberg  <wl@gnu.org>
+
+	[bdf] Fix Savannah bug #41692.
+
+	bdflib puts data from the input stream into a buffer in chunks of
+	1024 bytes.  The data itself gets then parsed line by line, simply
+	increasing the current pointer into the buffer; if the search for
+	the final newline character exceeds the buffer size, more data gets
+	read.
+
+	However, in case the current line's end is very near to the buffer
+	end, and the keyword to compare with is longer than the current
+	line's length, an out-of-bounds read might happen since `memcmp'
+	doesn't stop properly at the string end.
+
+	* src/bdf/bdflib.c: s/ft_memcmp/ft_strncmp/ to make comparisons
+	stop at string ends.

+
+	This is useful for OpenType features like `c2sc' (caps to small

+
+	* src/autofit/afscript.h: Add more standard characters.

+
+	[autofit] Fix Indic scripts.
+
+	Split the single, incorrect Indic entry into separate scripts so
+	that the covered ranges are the same: Bengali, Devanagari, Gujarati,
+	Gurmukhi, Kannada, Limbu, Malayalam, Oriya, Sinhala, Sundanese,
+	Syloti Nagri, Tamil, Telugu, and Tibetan.  At the same time, remove
+	entries for Meetei Mayek and Sharada – the Unicode ranges were
+	incorrect (and nobody has complained about that), fonts are scarce
+	for those scripts, and the Indic auto-hinter support is rudimentary
+	anyways.
+
+	* src/autofit/afscript.h: Updated, using AF_CONFIG_OPTION_INDIC and
+	AF_CONFIG_OPTION_CJK.
+
+	* src/autofit/afstyles.h (STYLE_DEFAULT_INDIC): New auxiliary macro.
+	Use it, together with AF_CONFIG_OPTION_INDIC and

+
+	* src/autofit/afranges.c [AF_CONFIG_OPTION_INDIC]: Updated.

+2014-01-03  Werner Lemberg  <wl@gnu.org>
+
+	[autofit] Fix handling of default coverages.
+
+	With this commit, the implementation of coverage handling is

+
+2014-01-01  Werner Lemberg  <wl@gnu.org>
+
+	[autofit] Add more styles.
+

+	auxiliary macros; use them to define styles for Cyrillic, Greek, and
+	Latin.
+
+	* src/autofit/afcover.h: Remove coverage for oldstyle figures.
+	Since those digits are used in combination with ordinary letters, it
+	makes no sense to handle them separately.
+
+	* src/autofit/afglobal.c (af_face_globals_get_metrics): Don't limit

+
+2014-01-01  Werner Lemberg  <wl@gnu.org>

+
+2013-12-30  Werner Lemberg  <wl@gnu.org>
+
+	[autofit] Don't combine multiple features into one set.
+
+	Combining them, as originally envisioned, would lead to much more

+	[ftrfork] Fix the face order difference between POSIX and Carbon.
+
+	The fragmented resources in Suitcase and .dfont should be reordered
+	when `POST' resource for Type1 is being restored, but reordering of
+	sfnt resources induces the different face order.  Now the ordering
+	is restricted to `POST' resource only, to prevent the different
+	order issue (e.g. the face index in the fontconfig cache generated
+	with Carbon framework is incompatible with that by FreeType 2
+	without Carbon framework.)  Found by Khaled Hosny and Hin-Tak Leung.

+
+	[autofit] Introduce `coverages'.
+
+	Coverages are the interface to the HarfBuzz library to access
+	OpenType features for handling glyphs not addressable by the cmap.
+
+	Right now, compilation of HarfBuzz is only added to the development
+	build.  A solution for standard build mode will be delayed until
+	HarfBuzz gets split into two libraries to avoid mutual dependencies
+	between FreeType and HarfBuzz.
+
+	Note that this is only a first step in handling coverages, basically
+	providing the framework only.  Code for handling selected OpenType
+	features (this is, actually using the data in `afcover.h') will
+	follow.

+
+	* src/cff/cf2font.c (cf2_computeDarkening): Avoid division by zero.
+

+	incorrect amount of darkening.

+
+	* src/cff/cf2font.c (cf2_computeDarkening): Initialize darkenAmount.
+
+	This line was lost in commit 89ca1fd6 (from 2013-06-25).  The effect
+	is to use a previous darkening amount when producing an unhinted,
+	unscaled outline.  This can cause autohint samples in ftgrid and
+	ftview to be based on darkened CFF outlines instead of unhinted,
+	undarkened ones.
+
+2013-09-29  Dave Arnold  <darnold@adobe.com>
+
+	Fix Savannah bug #39295.
+
+	The bug was caused by switching to the initial hintmap (the one in
+	effect when `moveto' executes) just before drawing the final element
+	in the charstring.  This ensured that the path was closed (in both
+	Character Space and Device Space).  But if the final element was a
+	curve and if the final hintmap was different enough from the initial
+	one, then the curve was visibly distorted.
+
+	The first part of the fix is to draw the final curve using the final
+	hintmap as specified by the charstring.  This corrects the
+	distortion but does not ensure closing in Device Space.  It may
+	require the rasterizer to automatically generate an extra closing
+	line.  Depending on the hintmap differences, this line could be from
+	zero to a couple pixels in length.
+
+	The second part of the fix covers the case where the charstring
+	subpath is closed with an explicit line.  We now modify that line's
+	end point to avoid the distortion.
+
+	Some glyphs in the bug report font (TexGyreHeros-Regular) that show
+	the change are:
+
+	  25ppem    S (98)
+	  24ppem    eight (52)
+	  25.5ppem  p (85)
+
+	Curves at the *end* of a subpath are no longer distorted.  However,
+	some of these glyphs have bad hint substitutions in the middle of a
+	subpath, and these are not affected.
+
+	The patch has been tested with a set of 106 fonts that shipped with
+	Adobe Creative Suite 4, together with 756 Open Source CFF fonts from
+	Google Fonts.  There are 1.5 million glyphs, of which some 20k are
+	changed with the fix.  A sampling of a few hundred of these changes
+	have been examined more closely, and the changes look good (or at
+	least acceptable).
+
+	* src/cff/cf2hints.h (CF2_GlyphPathRec): New element `pathIsClosing'
+	to indicate that we synthesize a closepath line.
+
+	* src/cff/cf2hints.c (cf2_glyphpath_init): Updated.
+	(cf2_glyphpath_pushPrevElem): If closing, use first hint map (for
+	`lineto' operator) and adjust hint zone.
+	For synthesized closing lines, use end point in first hint zone.
+	(cf2_glyphpath_lineTo): Take care of synthesized closing lines.  In
+	particular, shift the detection of zero-length lines from character
+	space to device space.
+	(cf2_glyphpath_closeOpenPath): Remove assertion.
+	Updated.

+
+	[autofit] Introduce data file for blue strings.
+
+	The idea is to have a central file which gets processed by a Perl
+	script to create proper `.c' and `.h' files using templates.  There
+	are two other reasons to do that:
+
+	  . The data file should be easily readable.  We use UTF-8 encoding
+	    which then gets converted to single bytes.
+
+	  . Since the number of supported scripts will increase soon, the
+	    current usage of blue string arrays is a waste of space.  Using
+	    the Perl script it is possible to imitate jagged arrays,
+	    defining enumeration constants as offsets into the arrays.
+
+	This commit only adds files without changing any functionality.
+
+	* src/autofit/afblue.dat: New data file.
+	* src/tools/afblue.pl: New Perl script for processing `afblue.dat'.
+
+	* src/autofit/afblue.cin, src/autofit/afblue.hin: New template files

+
+	Speed up ARMv7 support.
+
+	When building for ARMv7 with thumb2 instructions, the optimized
+	`FT_MulFix_arm' assembly routine was not being used.
+
+	The reason for this is in the `ftconfig.h' header, namely:
+
+	- The assembly routine uses the `smull' instruction which is not
+	  available when generating Thumb-1 machine code.  It is available
+	  in Thumb-2 mode, though.
+
+	- The header was written a long time ago before Thumb-2 became
+	  widely popular (e.g. with Android).  So it simply doesn't use the
+	  assembly routine if the `__thumb__' built-in macro is defined.
+
+	- When compiling in Thumb-2 mode, the compiler will define both
+	  `__thumb__' and `__thumb2__'.
+
+	By checking for `(__thumb2__ || !__thumb__)', we ensure that the
+	assembly routine is only avoided when generating Thumb-1 code.
+
+	Given that this is performance-sensitive function, this improves
+	`ftbench' as follows on a Galaxy Nexus:

+
+	[smooth] Sub-banding protocol revision.
+
+	Rasterization sub-banding is utilized at large sizes while using a
+	rather small fixed memory pool.  Indeed it is possible to make an
+	educated guess how much memory is necessary at a given size for a
+	given glyph.  It turns out that, for a large majority of European
+	glyphs, you should store about 8 times more boundary pixels than
+	their height.  Or, vice versa, if your memory pool can hold 800
+	pixels the band height should be 100 and you should sub-band
+	anything larger than that.  Should you still run out of memory,
+	FreeType bisects the band but you have wasted some time.  This is
+	what has been implemented in FreeType since the beginning.
+
+	It was overlooked, however, that the top band could grow to twice
+	the default band size leading to unnecessary memory overflows there.
+	This commit fixes that.  Now the bands are distributed more evenly
+	and cannot exceed the default size.
+
+	Now the magic number 8 is really suitable for rather simple European
+	scripts.  For complex Chinese logograms the magic number should be
+	13 but that is subject for another day.
+
+	* src/smooth/ftgrays.c (gray_convert_glyph): Revise sub-banding
+	protocol.
+

+	file includes non-existing symbols.  Reported by Ryan Schmidt.

+
+	* builds/unix/unix-cc.in (LINK_LIBRARY): Use `-export-symbols'.
+
+	This was commented about 10 years ago – I think the reason then to

+
+	[truetype] Improve the recursive reference detector.
+
+	The previous fix for #46372 misunderstood a composite glyph referring

+
+2016-05-07  Werner Lemberg  <wl@gnu.org>
+
+	[cache] Allow value 0 for face ID.
+
+	We never dereference `face_id', and some implementations might use a

+
+	* src/cache/ftccmap.c (FTC_CMapCache_Lookup), src/cache/ftcmanag.c
+	(FTC_Manager_LookupFace, FTC_Manager_RemoveFaceID): Remove test for

+
+2016-05-05  Alexei Podtelezhnikov  <apodtele@gmail.com>
+
+	[smooth] More efficient accounting of conic splits and draws.
+
+	A single decrement counter of segments to draw, instead of an array,

+
+	As FreeType depends on zlib, if we don't install zlib (e.g., because

+
+	[autofit] Add support for Georgian scripts.
+
+	Georgian is problematic, since `uppercase' forms of Mkhedruli
+	(called Mtavruli) are not yet defined in Unicode, which means that
+	proper blue zones can't be defined.  However, there is already a
+	proposal submitted to Unicode; see
+
+	  https://www.unicode.org/L2/L2016/16034-n4707-georgian.pdf
+
+	Additionally, due to historical reasons, Unicode treats Khutsuri as
+	the same script as Mkhedruli, and so does OpenType.  However, since
+	the two scripts have completely different shapes it can happen that
+	blue zones differ considerably.  The tag `geok' used here (derived
+	from ISO 15924) to differentiate the two scripts is not an OpenType
+	tag in use.  If we now have a font that contains both glyphs for
+	Mkhedruli and Khutsuri, and it uses OpenType features for both also,
+	HarfBuzz unavoidably treats all glyphs as `geor'.  As a consequence,
+	blue zones for `geok' are not used for glyphs involved in the
+	OpenType features.
+
+	An issue not yet resolved is which OpenType feature should be used
+	to access Mtavruli glyph shapes; right now, FreeType doesn't set up
+	support for them, but it is easy to add them later on as soon as
+	more information is available.

+
+	[autofit] Fix handling of default script.
+
+	Patch taken from ttfautohint, commit
+	071ae2c00e0d67f9d19418f4fade1c23d27dc185.
+
+	There were two bugs.
+
+	  - We now use non-standard script tags like `khms' for special
+	    purposes.  However, HarfBuzz maps such tags to `DFLT', and
+	    without this commit the associated lookups were incorrectly
+	    assigned to the non-standard tags.
+
+	  - Let's assume we have a Bengali font, and the font's `DFLT'
+	    script tag handles the necessary lookups for Bengali, too.
+	    Without this commit, the `DFLT' lookups were assigned to
+	    ttfautohint's default script (usually `latn') before the
+	    standard lookups for Bengali were handled.
+
+	    We now have the following order while searching for covered
+	    glyph indices.
+
+	      special features of scripts (e.g. `sups' for Cyrillic)
+	      Unicode mappings of scripts
+	      remaining features of scripts (especially important for Indic
+	        scripts)
+	      default features of default script

+
+	[autofit] Introduce subscript top blue zones.
+
+	This feature is mainly for Khmer: The idea is to avoid a clash

+
+	This only works for character clusters mapped to multiple glyphs.
+

+
+	[autofit] Rewrite HarfBuzz interface to support character clusters.
+
+	Scripts like Khmer have blue zones that can't be directly
+	represented by Unicode characters.  Instead, it is necessary to let
+	HarfBuzz convert character clusters into proper glyph representation
+	forms, then deriving the blue zone information from the resulting
+	glyphs.
+
+	* src/autofit/hbshim.c, src/autofit/hbshim.h: Replaced by...
+	* src/autofit/afshaper.c, src/autofit/afshaper.h: ... these two new
+	files, providing a new API to access HarfBuzz.
+
+	The new API manages a HarfBuzz buffer with `af_shaper_buf_create'
+	and `af_shaper_buf_destroy'.  The buffer receives a UTF8 encoded
+	string with function `af_shaper_get_cluster', and the resulting
+	glyph data (indices, advance widths, vertical offsets) can be
+	iteratively accessed with function `af_shaper_get_elem'.

+
+	[smooth] Faster alternative line renderer.
+
+	This implementation renders the entire line segment at once without

+	reducing the number of divisions to just two per line segment, which

+	Notably, the progression from cell to cell does not itself require any
+	divisions at all.  The speed improvement is more noticeable at larger

+	[sfnt] Improve handling of invalid SFNT table entries (#45987).
+
+	This patch fixes weaknesses in function `tt_face_load_font_dir'.
+
+	- It incorrectly assumed that valid tables are always at the

+	  entries (which are ignored) were never seen.
+
+	- Duplicate table entries (this is, having the same tag) were not

+
+	- The number of valid tables was sometimes too large, leading to

+
+	[autofit] Redesign code ranges (1/2).
+
+	This patch introduces auxiliary code ranges that identify no-base
+	characters; they refer to glyphs of a script that should be hinted
+	without alignments to blue zones (mostly diacritics).
+
+	It also splits off ranges for fallback scripts that handle subscript
+	and superscript characters not covered by OpenType features.  For
+	example, this greatly helps improve the hinting of various phonetic
+	alphabets, which contain a large amount characters that look like
+	superscript glyphs.
+
+	Finally, code ranges are updated to Unicode 8.0, and enclosed
+	characters are removed in general since they normally look better if
+	they stay unhinted.
+
+	* src/autofit/afranges.c (af_latn_uniranges): Updated to Unicode
+	8.0.
+	Split off superscript-like and subscript-like glyphs into...
+
+	(af_latb_uniranges, af_latp_uniranges): ... these two new arrays.
+
+	(af_xxxx_nobase_uniranges): New arrays that hold no-base characters
+	of the corresponding character ranges.

+
+	This is a severe bug: We've missed one level of indirection, as

+
+	Another adjustment to header locations.
+
+	This change is a result of a discussion thread on freetype-devel

+
+	Re-introduce the `freetype2' subdirectory for all FreeType header

+
+	Fix Savannah bug #45097.
+
+	We no longer `pollute' the namespace of possible header file names;
+	instead we move `ft2build.h' up by one level so that it gets
+	installed in the default include directory (e.g.,
+	/usr/local/include).  After this commit, only `ft2build.h' stays in
+	the compiler's include path.
+
+	No visible changes for the user who follows the standard FreeType
+	header inclusion rules.

+	Make Jam support work again.
+
+	This is just very basic stuff and just a little bit tested on

+2015-06-06  Ashish Azad  <ashish.azad@samsung.com>
+

+
+2015-06-03  Werner Lemberg  <wl@gnu.org>
+
+	[truetype] Fix memory leak.
+
+	Problem reported by Grissiom <chaos.proton@gmail.com>; in
+
+	  https://lists.nongnu.org/archive/html/freetype/2015-05/msg00013.html
+
+	there is an example code to trigger the bug.
+

+
+2015-06-02  Werner Lemberg  <wl@gnu.org>
+
+	[raster] Add more tracing.
+

+
+2015-05-31  Werner Lemberg  <wl@gnu.org>
+
+	[truetype] In GX, make private point numbers work correctly.
+
+	This is completely missing in Apple's documentation: If a `gvar'
+	tuple uses private point numbers (this is, deltas are specified for
+	some points only), the uncovered points must be interpolated for
+	this tuple similar to the IUP bytecode instruction.  Examples that
+	need this functionality are glyphs `Oslash' and `Q' in Skia.ttf.
+
+	* src/truetype/ttgxvar.c (tt_delta_shift, tt_delta_interpolate,
+	tt_handle_deltas): New functions.
+	(TT_Vary_Get_Glyph_Deltas): Renamed to...
+	(TT_Vary_Apply_Glyph_Deltas): ... this; it directly processes the
+	points and does no longer return an array of deltas.
+	Add tracing information.
+	Call `tt_handle_deltas' to interpolate missing deltas.
+	Also fix a minor memory leak in case of error.
+
+	* src/truetype/ttgxvar.h: Updated.

+	Change `symmetrical smoothing' to TRUE, since FreeType produces
+	exactly this.
+
+	* src/truetype/ttinterp.c (Ins_GETINFO): Fix selector/return bit
+	values for symmetrical smoothing, namely 11/18.
+	Handle bits for vertical LCD subpixels (8/15) and Gray ClearType
+	(12/19).
+
+2015-05-23  Werner Lemberg  <wl@gnu.org>
+
+	[truetype] Minor.
+
+	* src/truetype/ttinterp.h (TT_ExecContext):

+
+2015-05-22  Werner Lemberg  <wl@gnu.org>
+
+	[truetype] Support selector index 3 of the INSTCTRL instruction.
+
+	This flag activates `native ClearType hinting', disabling backward
+	compatibility mode as described in Greg Hitchcocks whitepaper.  In
+	other words, it enables unrestricted functionality of all TrueType
+	instructions in ClearType.
+
+	* src/truetype/ttgload.c (tt_get_metrics): Call `sph_set_tweaks'
+	unconditionally.
+	(tt_loader_init): Unset `ignore_x_mode' flag if bit 2 of
+	`GS.instruct_control' is active.
+
+	* src/truetype/ttinterp.c (Ins_INSTCTRL): Handle selector index 3.

+
+2015-05-17  Werner Lemberg  <wl@gnu.org>
+
+	[truetype] Fix loading of composite glyphs.
+
+	* src/truetype/ttgload.c (TT_Load_Composite_Glyph): If the
+	ARGS_ARE_XY_VALUES flag is not set, handle argument values as
+	unsigned.  I trust `ttx' (which has exactly such code) that it does
+	the right thing here...
+
+	The reason that noone has ever noticed this bug is probably the fact
+	that point-aligned subglyphs are rare, as are subglyphs with a
+	number of points in the range [128;255], which is quite large (or
+	even in the range [32768;65535], which is extremely unlikely).
+
+2015-05-12  Chris Liddell  <chris.liddell@artifex.com>
+
+	[cff] Make the `*curveto' operators more tolerant.
+
+	* src/cff/cf2intrp.c (cf2_interpT2CharString): The opcodes
+	`vvcurveto', `hhcurveto', `vhcurveto', and `hvcurveto' all iterate,
+	pulling values off the stack until the stack is exhausted.
+	Implicitly the stack must be a multiple (or for subtly different
+	behaviour) a multiple plus a specific number of extra values deep.
+	If that's not the case, enforce it (as the old code did).
+
+2015-05-12  Chris Liddell  <chris.liddell@artifex.com>
+
+	[cff] fix incremental interface with new cff code.
+
+	* src/cff/cf2ft.c (cf2_getSeacComponent): When using the incremental
+	interface to retrieve glyph data for a SEAC, it be left to the
+	incremental interface callback to apply the encoding to raw
+	character index (as it was in the previous code).

+
+	[raster] Fix Savannah bug #44022.
+
+	Add fallback for glyphs with degenerate bounding boxes.
+
+	If a glyph has only one very narrow feature, the bbox can end up
+	with either the width or height of the bbox being 0, in which case
+	no raster memory is allocated and no attempt is made to render the
+	glyph.  This is less than ideal when the drop-out compensation in
+	the rendering code would actually result in the glyph being
+	rendered.
+
+	This problem can be observed with the `I' glyph (gid 47) in the
+	Autodesk RomanS TrueType font.
+
+	* src/raster/ftrend1.c (ft_raster1_render): Add a fallback if either
+	dimension is zero to explicitly round up/down (instead of simply
+	round).
+
+2015-01-17  Werner Lemberg  <wl@gnu.org>
+
+	Add some tools to handle yearly copyright notice updates.
+
+	We are now following the GNU guidelines: A new release automatically
+	means that the copyright year of all affected files gets updated; it
+	is no longer used to track years of modification changes.
+
+	* src/tools/update-copyright-year: New Perl script.
+	* src/tools/update-copyright: New shell script that calls
+	`update-copyright-year' on all files.
+	* src/tools/no-copyright: Exceptions that should not be handled by

+
+	[autofit] Add embedded array of segments and edges.
+
+	Avoids multiple mallocs per typical glyphs.
+
+	With this and recent changes to avoid mallocs, the thread-safe

+	cached singleton.
+
+	* src/autofit/afhints.h (AF_SEGMENTS_EMBEDDED, AF_EDGES_EMBEDDED):

+	Update prototype.

+
+2015-01-14  Behdad Esfahbod  <behdad@behdad.org>
+
+	[autofit] Reuse slot glyph loader.
+
+	No need to create a new glyph loader; we can reuse the one from
+	`slot->internal->loader'.  It's hard to tell why it was written that
+	way originally, but new code looks sound and correct to me, and
+	avoids lots of allocations.
+
+	* src/autofit/afloader.c (af_loader_init): Change return type to
+	`void'.
+	Don't call `FT_GlyphLoader_New'.
+	(af_loader_reset): Don't call `FT_GlyphLoader_Rewind'.
+	(af_loader_load_g): Update code to use `internal->loader', which
+	doesn't need copying of data.
+
+	* src/autofit/afloader.h (AF_LoaderRec): Remove `gloader' member.
+	Update prototype.
+
+	* src/autofit/afmodule.c (af_autofitter_load_glyph): Updated.
+
+2015-01-14  Behdad Esfahbod  <behdad@behdad.org>
+
+	[autofit] Remove (unused) support for composite glyphs.
+
+	We never have to deal with composite glyphs in the autohinter, as
+	those will be loaded into FORMAT_OUTLINE by the recursed
+	`FT_Load_Glyph' function.
+
+	In the rare cases that FT_LOAD_NO_RECURSE is set, it will imply
+	FT_LOAD_NO_SCALE as per `FT_Load_Glyph', which then implies
+	FT_LOAD_NO_HINTING:
+
+	  /* resolve load flags dependencies */
+
+	  if ( load_flags & FT_LOAD_NO_RECURSE )
+	    load_flags |= FT_LOAD_NO_SCALE         |
+	                  FT_LOAD_IGNORE_TRANSFORM;
+
+	  if ( load_flags & FT_LOAD_NO_SCALE )
+	  {
+	    load_flags |= FT_LOAD_NO_HINTING |
+	                  FT_LOAD_NO_BITMAP;
+
+	    load_flags &= ~FT_LOAD_RENDER;
+	  }
+
+	and as such the auto-hinter is never called.  Thus, the recursion in
+	`af_loader_load_g' never actually happens.  So remove the depth
+	counter as well.
+
+	* src/autofit/afloader.c (af_loader_load_g): Remove `depth'
+	parameter.
+	<FT_GLYPH_FORMAT_COMPOSITE>: Remove associated code.
+	(af_loader_load_glyph): Updated.
+
+2015-01-14  Behdad Esfahbod  <behdad@behdad.org>
+
+	[raster] Fix uninitialized memory access.
+
+	Apparently `ras.cProfile' might be uninitialized.  This will be the
+	case if `ras.top == ras.cProfile->offset', as can be seen in
+	`End_Profile'.  The overshoot code introduced in a change `Fix B/W
+	rasterization of subglyphs with different drop-out modes.' (from
+	2009-06-18) violated this, accessing `ras.cProfile->flags'
+	unconditionally just before calling `End_Profile' (which then
+	detected that `cProfile' is uninitialized and didn't touch it).
+
+	This was harmless, and was not detected by valgrind before because
+	the objects were allocated on the `raster_pool', which was always
+	initialized.  With recent change to allocate raster buffers on the
+	stack, valgrind now reported this invalid access.
+
+	* src/raster/ftraster.c (Convert_Glyph): Don't access an
+	uninitialized `cProfile'.
+
+2015-01-14  Behdad Esfahbod  <behdad@behdad.org>
+
+	[smooth] Fix uninitialized memory access.
+
+	Looks like `ras.span_y' could always be used without initialization.
+	This was never detected by valgrind before because the library-wide
+	`raster_pool' was used for the worker object and `raster_pool' was
+	originally zero'ed.  But subsequent reuses of it were using `span_y'
+	uninitialized.  With the recent change to not use `render_pool' and
+	allocate worker and buffer on the stack, valgrind now detects this
+	uninitialized access.
+
+	* src/smooth/ftgrays.c (gray_raster_render): Initialize
+	`ras.span_y'.
+
+2015-01-14  Behdad Esfahbod  <behdad@behdad.org>

+
+2015-01-14  Behdad Esfahbod  <behdad@behdad.org>
+
+	[base] Don't allocate `library->raster_pool' anymore.
+
+	It's unused after the following commits:
+
+	  [raster] Allocate render pool for mono rasterizer on the stack.
+	  [raster] Remove 5-level gray AA mode from monochrome rasterizer.
+
+	The value of FT_RENDER_POOL_SIZE still serves the purpose it used to
+	serve, which is, to adjust the pool size.  But the pool is now
+	allocated on the stack on demand.
+
+	* src/base/ftobjs.c (FT_New_Library, FT_Done_Library): Implement.
+
+2015-01-14  Behdad Esfahbod  <behdad@behdad.org>
+
+	[base] Do not reorder library->renderers upon use.
+
+	Instead of keeping `library->renderers' in a MRU order, just leave
+	it as-is.  The MRU machinery wasn't thread-safe.
+
+	With this patch, rasterizing glyphs from different faces from
+	different threads doesn't fail choosing rasterizer
+	(FT_Err_Cannot_Render_Glyph).
+
+	Easiest to see that crash was to add a `printf' (or otherwise let
+	thread yield in FT_Throw with debugging enabled).
+
+	* src/base/ftobjs.c (FT_Render_Glyph_Internal), src/base/ftoutln.c
+	(FT_Outline_Render): Don't call `FT_Set_Renderer'.
+
+2015-01-14  Behdad Esfahbod  <behdad@behdad.org>
+
+	[raster] Allocate render pool for mono rasterizer on the stack.
+
+	Instead of using the `render_pool' member of `FT_Library' that is

+
+	With this patch, rasterizing glyphs from different faces from
+	different threads doesn't crash in the monochrome rasterizer.
+

+
+	[raster] Remove 5-level gray AA mode from monochrome rasterizer.
+

+
+	[truetype] Allocate TT_ExecContext in TT_Size instead of TT_Driver.
+
+	Previously the code had stipulation for using a per-TT_Size exec

+	using the singleton `TT_ExecContext' that was stored in `TT_Driver'.

+	strikes in advance.
+
+	Reported as
+
+	  https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=353
+
+	* src/tools/ftfuzzer/ftfuzzer.cc: Include `stdlib.h' for `rand'.

+	(without repetition) out of the value set [1,N].
+	(LLVMFuzzerTestOneInput): Use it to test only up to 10 bitmap

+
+	[truetype] Fix linear metrics of GX variation fonts (#49829).
+
+	When asking for an unhinted non-default variations,
+	`linearVertAdvance' is currently the value from the `hmtx' table

+
+	* src/base/ftobjs.c (FT_Open_Face): Code moved to...
+	(ft_open_face_internal): ... this function.
+	Add a parameter to control whether we try special Mac font handling
+	in case of failure.
+	(FT_Open_Face, FT_New_Face, FT_New_Memory_Face,

+	field.
+
+	* src/sfnt/sfobjs.c (sfnt_init_face): Compute `use_fvar', also

+	the following error.
+
+	  ftgzip.c
+	  zlib-1.2.8\zlib.h(86): error C2061:

+	                          error count exceeds 100; stopping compilation
+
+	The error happens because FreeType keeps an own copy of zlib-1.1.4
+	under `src/gzip'.  When building `src/gzip/ftgzip.c' with
+	FT_CONFIG_OPTION_SYSTEM_ZLIB defined, it uses
+
+	  #include <zlib.h>
+
+	which correctly finds an external `zlib.h', but `zlib.h' itself has
+	a line
+
+	  #include "zconf.h"
+

+	compiling the files in `src/gzip'.
+
+	* src/gzip/zconf.h: Rename to...
+	* src/gzip/ftzconf.h: ... this.

+	[pcf] Enrich family name with foundry name and glyph width info.
+
+	This is a very old patch from openSuSE (from 2006, submitted to
+	FreeType in 2011) that I forgot to apply.
+
+	  https://build.opensuse.org/package/view_file/openSUSE:Factory/freetype2/freetype2-bitmap-foundry.patch
+
+	Prepend the foundry name plus a space to the family name.  There are
+	many fonts just called `Fixed' which look completely different, and
+	which have nothing to do with each other.  When selecting `Fixed' in
+	KDE or Gnome one gets results that appear rather random, the style
+	changes often if one changes the size and one cannot select some
+	fonts at all.
+
+	We also check whether we have `wide' characters; all put together,
+	we get family names like `Sony Fixed' or `Misc Fixed Wide'.
+
+	* src/pcf/pcfread.c (pcf_load_font): Implement it.
+
+	* docs/CHANGES: Document it.

+

+
+	[truetype] Speed up `TT_Load_Glyph'.
+
+	This avoids additional calls to `tt_face_lookup_table' for the

+
+	* include/freetype/internal/tttypes.h (TT_LoaderRec): Move

+
+	[truetype] Introduce dynamic limits for some bytecode opcodes.
+
+	This speeds up FreeType's handling of malformed fonts.
+
+	* src/truetype/ttinterp.c (TT_RunIns): Set up limits for the number
+	of twilight points, the total number of negative jumps, and the
+	total number of loops in LOOPCALL opcodes.  The values are based on
+	the number of points and entries in the CVT table.
+	(Ins_JMPR): Test negative jump counter.
+	(Ins_LOOPCALL): Test loopcall counter.

+
+	* docs/CHANGES: Updated.
+
+2016-09-25  Werner Lemberg  <wl@gnu.org>
+
+	[truetype] Sanitize only last entry of `loca' table.
+
+	Without this patch, a loca sequence like `0 100000 0 100000 ...',
+	where value 100000 is larger than the `glyf' table size, makes
+	FreeType handle the whole `glyf' table as a single glyph again and
+	again, which is certainly invalid (and can be very slow, too).
+

+
+	We don't need some divisions if a line segments stays within a single

+
+2016-09-11  Alexei Podtelezhnikov  <apodtele@gmail.com>
+
+	[smooth] Fix valgrind warning and reoptimize.
+
+	The algorithm calls `gray_set_cell' at the start of each new contour
+	or when the contours cross the cell boundaries. Double-checking for

+
+	* src/smooth/ftgrays.c (gray_set_cell): Remove check for a new cell.

+
+	[smooth] Simplify span rendering more.
+
+	It turns out that there is significant cost associated with `FT_Span'
+	creation and calls to `gray_render_span' because it happens so
+	frequently. This removes these steps from our internal use but leaves
+	it alone for `FT_RASTER_FLAG_DIRECT" to preserve API. The speed gain
+	is about 5%.
+
+	* src/smooth/ftgrays.c (gray_render_span): Removed. The code is

+
+	[sfnt] Fix `FT_Get_Advance' for bitmap strikes.
+
+	`FT_Get_Advance' returns 0 for bitmap fonts.  It first gets the
+	advance value from the font table and then scales it by the
+	`font->size->metrics->x_scale' field.  But `FT_Select_Size' doesn't
+	set that value for bitmap fonts and the advance gets scaled to zero.
+
+	Taken from

+
+	[sfnt, truetype] Don't abort on invalid `maxComponentDepth'.
+
+	Since 2016-05-16 we detect infinite recursion directly.
+
+	* src/sfnt/ttload.c (tt_face_load_maxp): Don't adjust
+	`maxComponentDepth'.
+	* src/truetype/ttgload.c (load_truetype_glyph): Don't abort if
+	`maxComponentDepth' is not valid.  Instead, simply adjust its value
+	and emit a tracing message.
+
+2016-07-26  Werner Lemberg  <wl@gnu.org>
+

+
+	No functional change.
+
+2016-07-22  Hin-Tak Leung  <htl10@users.sourceforge.net>
+
+	[truetype] Record the end of IDEFs.
+
+	To match the logic in FDEF.  The value of the end is only used for
+	bound-checking in `Ins_JMPR', so it may not have been obvious that
+	it was not recorded.  Tested (as part of Font Validator 2.0) all the
+	fonts on Fedora and did not see any change.
+
+	* src/truetype/ttinterp.c (Ins_IDEF): Updated.
+
+2016-07-19  Werner Lemberg  <wl@gnu.org>

+
+2016-07-17  Werner Lemberg  <wl@gnu.org>
+

+	(TT_RunIns): Add it.
+
+2016-07-16  Werner Lemberg  <wl@gnu.org>
+
+	[truetype] Add bytecode support for GX variation fonts.
+
+	This commit implements undocumented (but confirmed) stuff from
+	Apple's old bytecode engine.
+
+	  GETVARIATION[], opcode 0x91
+	    This opcode pushes normalized variation coordinates for all axes
+	    onto the stack (in 2.14 format).  Coordinate of first axis gets
+	    pushed first.
+
+	  GETINFO[], selector bit 3
+	    If GX variation support is enabled, bit 10 of the result is set
+	    to 1.
+
+	* src/truetype/ttinterp.c: Include FT_MULTIPLE_MASTERS_H.
+	(opcode_name) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Updated.
+	(Ins_GETINFO) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Handle selector
+	bit 3, checking support for variation glyph hinting.
+	(Ins_GETVARIATION) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: New function
+	to implement opcode 0x91.
+	(TT_RunIns) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Handle opcode 0x91.

+
+	[truetype] Fix GX delta tracing.

+
+2016-07-16  Behdad Esfahbod  <behdad@behdad.org>
+
+	[truetype] More fixes for GX.
+
+	This finally fixes the rendering of the cyclist and the lizard in
+	the `Zycon' font.
+
+	* src/truetype/ttgxvar.c (ft_var_readpackedpoints): `first' point
+	index is always cumulative.
+
+	(tt_handle_deltas): Rename to...
+	(tt_interpolate_deltas): ... This.
+	Add new parameter for output point array.
+	Update caller.
+
+	(TT_Vary_Apply_Glyph_Deltas): Add `points_out' array; it now holds
+	the intermediate results of `tt_interpolate_deltas' that are to be
+	added to `outline->points'.
+
+2016-07-15  Werner Lemberg  <wl@gnu.org>
+
+	* src/autofit/aflatin.c (af_latin_hints_compute_segments): Thinko.

+
+	[autofit] Update and improve segment and edge tracing.
+
+	* src/autofit/afhints.c (af_glyph_hints_dump_segments): Trace
+	`delta' also.
+	Don't show first point of segment as a replacement for `pos'; this
+	is (a) misleading, since the difference to `pos' can be almost
+	arbitrarily large in corner cases, and (b) it is better to have all
+	segment data in font units instead of a single value given in output
+	space coordinates.
+	Improve layout.
+	(af_glyph_hints_dump_edges): Show px->units and units->px conversion
+	values for convenience.
+	Improve layout.
+
+2016-07-15  Werner Lemberg  <wl@gnu.org>
+
+	[autofit] For edges, reject segments wider than 1px (#41334).

+
+	* src/autofit/aflatin.c (af_latin_hints_compute_segments): Compute

+2016-07-14  Behdad Esfahbod  <behdad@behdad.org>
+
+	[truetype] Fix gxvar delta interpolation.
+
+	The coordinates of the base font should be used for interpolation
+	purposes, NOT the current points (i.e., the result of accumulation
+	of previous deltas).
+
+	* src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Initialize

+
+	[base] Remove a check for resource ID in the resource fork driver.
+
+	LastResort.dfont has a marginal resource ID 0xFFFF for sfnt
+	resource.  Inside Macintosh: More Macintosh Toolbox, `Resource IDs'
+	(1-46), tells that some IDs are reserved and should not be used.
+	FreeType2 just uses resource ID to sort the fragmented resource.
+	To accept the marginal fonts, the checking is removed.
+
+	* src/base/ftrfork.c (FT_Raccess_Get_DataOffsets): Remove res_id
+	validity check, fix a trace message format.
+
+2017-09-08  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	[sfnt, truetype] Register the tags for marginal fonts.
+
+	The first 32bit of standard TrueType variants is 0x00010000,
+	`OTTO', `ttcf', `true' or `typ1'.  2 marginal dfonts on legacy Mac
+	OS X, Keyboard.dfont and LastResort.dfont, have the sfnt resources
+	starting 0xA5 followed by `kbd' or `lst'.  Considering the following
+	data could be parsed as conventional TrueType fonts, the header
+	checking is updated to allow these tags.  It seems that recent Mac
+	OS X has already switched to normal TTF for these fonts.
+
+	See the discussion at
+	http://u88.n24.queensu.ca/exiftool/forum/index.php?topic=3931.0
+
+	* include/freetype/tttags.h (TTAG_0xA5kbd, TTAG_0xA5lst): New header
+	tags for Keyboard.dfont and LastResort.dfont.
+	* src/sfnt/sfobjs.c (sfnt_open_font): Accept the sfnt resource
+	starts with TTAG_0xA5kbd or TTAG_0xA5lst.
+	* src/truetype/ttobjs.c (tt_face_init): Accept the face with the
+	format tag is TTAG_0xA5kbd or TTAG_0xA5lst.
+
+2017-09-05  Werner Lemberg  <wl@gnu.org>
+
+	Fix multiple calls of `FT_Bitmap_Convert'.
+
+	The documentation of `FT_Bitmap_Convert' says that multiple calls do
+	proper reallocation of the target FT_Bitmap object.  However, this
+	failed for the sequence
+
+	  non-empty bitmap
+	  empty bitmap
+	  non-empty bitmap
+
+	Reason was that `FT_Bitmap_Convert' only reallocated the bitmap
+	buffer if it became too small; it didn't make the buffer smaller.
+	For an empty bitmap following a non-empty one, only the buffer
+	dimension got set to zero, without deallocation.  If the next call
+	was a non-empty buffer again, an assertion in `ft_mem_qrealloc' was
+	triggered.
+
+	* src/base/ftbitmap.c (FT_Bitmap_Convert): Always reallocate target
+	buffer to the correct size.
+
+	* docs/CHANGES: Document it.
+
+2017-09-05  Werner Lemberg  <wl@gnu.org>
+
+	[bdf] Fix size and resolution handling.
+
+	* src/bdf/bdfdrivr.c (BDF_Face_Init): Use `SIZE' values if
+	`POINT_SIZE', `RESOLUTION_X', or `RESOLUTION_Y' properties are
+	missing.
+

+

+
+	Modern bitmap-only SFNTs like `NotoColorEmoji.ttf' don't contain

+
+	[smooth] Harmony LCD rendering.
+
+	This is a new technology for LCD-optimized rendering. It capitalizes
+	on the fact that each color channel grid is shifted by a third of a
+	pixel.  Therefore it is logical to render 3 separate monochrome
+	bitmaps shifting the outline by 1/3 pixel, and then combine them.
+	Importantly, the resulting output does not require additional LCD
+	filtering.

+
+	* src/truetype/ttgload.c (load_truetype_glyph): The new OpenType
+	version explicitly allows all negative values for the number of

+
+	Handle some integer overflow run-time errors (#46149, #48979).
+
+	This commit (mainly for 32bit CPUs) is the first of a series of
+	similar commits to handle known integer overflows.  Basically, all
+	of them are harmless, since they affect rendering of glyphs only,
+	not posing security threats.  It is expected that fuzzying will show
+	up more overflows, to be fixed in due course.
+
+	The idea is to mark places where overflows can occur, using macros
+	that simply cast to unsigned integers, because overflow arithmetic
+	is well defined in this case.  Doing so suppresses run-time errors
+	of sanitizers without adding computational overhead.
+
+	* include/freetype/internal/ftcalc.h (OVERFLOW_ADD_INT,

+2017-05-28  Werner Lemberg  <wl@gnu.org>
+
+	[cff] s/cf2_floatToFixed/cf2_doubleToFixed/.
+
+	The new name better describes what the macro actually does;
+	additionally, we don't need a trailing `f' for literals (there was
+	only a single such instance in the code, but this caused a clang
+	warning because the macro itself uses `double' literals).

+
+	[smooth] Implement minimal dynamic padding for LCD filtering.
+
+	Extra bitmap padding for LCD filtering depends on the filter.  The
+	default 5-tap filter needs 2 extra subpixels.  The light 3-tap filter
+	needs only 1 extra subpixel.  This space could be already available
+	due to rounding.  In order to optimize the padding, we now expand
+	CBox for the given filter weights before rounding.
+
+	This change breaks current Skia (and Firefox).

+	[autofit] Make autohint warping NORMAL option.
+
+	This moves warping option from LIGHT to NORMAL mode.  This makes LIGHT

+	Therefore, LIGHT is now ready to return fractional advance.  As a
+	NORMAL option, warping substitutes normal hinting.

+	[truetype] Make `IUP' gvar deltas do the same as Apple (#50832).
+
+	When points are not touched by gvar interpolation deltas, FreeType
+	gave a slightly different result than Apple's CoreText.
+
+	The OpenType working group will update the specification to document
+	the following behaviour: If the two points with deltas to the `left'
+	and `right' of the untouched point have the same coordinate, then
+	the inferred delta for the untouched point should be zero.
+
+	* src/truetype/ttgxvar.c (tt_delta_interpolate): Implement new
+	behaviour.

+
+	Add new `slight' auto-hinting mode.
+
+	This mode uses fractional advance widths and doesn't scale glyphs
+	horizontally, only applying vertical scaling and hinting.
+
+	At the same time, the behaviour of the `light' auto-hinter gets
+	restored for backward compatibility: Both vertical and horizontal
+	scaling is again based on rounded metrics values (this was changed
+	in a commit from 2017-03-30 as a side effect).  To be more precise,
+	the behaviour is restored for TrueType fonts only; for other font
+	formats like Type 1, this is a new feature of the `light' hinting
+	mode.
+
+	* include/freetype/freetype.h (FT_LOAD_TARGET_SLIGHT): New macro.
+	(FT_RENDER_MODE_SLIGHT): New render mode.

+
+	[autofit] Prevent overlapping blue zones.
+
+	Problem reported as
+
+	  https://github.com/google/fonts/issues/632
+
+	The font in question (Nunito) has values 705 and 713 for the
+	reference and overshoot values, respectively, of the first blue
+	zone.  Blue zone 2, however, has value 710 for both the reference
+	and overshoot.  At 12ppem, reference and overshoot of blue zone 0
+	becomes 8px, while blue zone 2 becomes 9px.
+
+	A peculiarity of this font is that the tops of isolated vertical
+	stems like `N' have a slight overshoot also.  The auto-hinter tries
+	to find the nearest blue zone using the *original* coordinates.  For
+	vertical stems, this is value 713.  For normal horizontal tops like
+	in character `E', this is value 710.  Since value 713 is mapped to
+	8px but value 710 to 9px, `N' and similar characters are one pixel
+	higher than `E', which looks very bad.
+
+	This commit sanitizes blue zones to avoid such a behaviour.

+
+	The number of lowercase characters for computing the top flat blue

+	FreeType must select between two different values, having a 50%

+  FreeType 2.9.1
+  ==============
+
+  Homepage: https://www.freetype.org
+
+  FreeType is a freely available software library to render fonts.
+
+  It  is  written  in  C,  designed to  be  small,  efficient,  highly
+  customizable, and  portable while capable of  producing high-quality
+  output  (glyph  images) of  most  vector  and bitmap  font  formats.
+
+  Please   read   the  docs/CHANGES   file,   it  contains   IMPORTANT
+  INFORMATION.
+
+  Read the  files `docs/INSTALL*'  for installation  instructions; see
+  the file `docs/LICENSE.TXT' for the available licenses.
+
+  The FreeType 2 API reference is located in `docs/reference'; use the
+  file   `ft2-toc.html'   as   the   top  entry   point.    Additional
+  documentation is available as a separate package from our sites.  Go
+  to
+
+    https://download.savannah.gnu.org/releases/freetype/
+
+  and download one of the following files.
+
+    freetype-doc-2.9.1.tar.bz2
+    freetype-doc-2.9.1.tar.gz
+    ftdoc291.zip
+
+  To view the documentation online, go to
+
+    https://www.freetype.org/freetype2/documentation.html
+
+
+  Mailing Lists
+  =============
+
+  The preferred way  of communication with the FreeType  team is using
+  e-mail lists.
+
+    general use and discussion:      freetype@nongnu.org
+    engine internals, porting, etc.: freetype-devel@nongnu.org
+    announcements:                   freetype-announce@nongnu.org
+    git repository tracker:          freetype-commit@nongnu.org
+
+  The lists are moderated; see
+
+    https://www.freetype.org/contact.html
+
+  how to subscribe.
+
+
+  Bugs
+  ====
+
+  Please submit bug reports at
+
+    https://savannah.nongnu.org/bugs/?group=freetype
+
+  Alternatively,    you   might    report    bugs    by   e-mail    to
+  `freetype-devel@nongnu.org'.   Don't  forget   to  send  a  detailed
+  explanation of the problem --  there is nothing worse than receiving
+  a terse message that only says `it doesn't work'.
+
+
+  Enjoy!

+The git  archive doesn't  contain pre-built configuration  scripts for
+UNIXish platforms.  To generate them say
+
+  sh autogen.sh
+
+which in turn depends on the following packages:
+
+  automake (1.10.1)
+  libtool (2.2.4)
+  autoconf (2.62)
+
+The versions given  in parentheses are known to  work.  Newer versions
+should work too, of course.   Note that autogen.sh also sets up proper
+file permissions for the `configure' and auxiliary scripts.
+
+The autogen.sh script  now checks the version of  above three packages
+whether they match the numbers  above.  Otherwise it will complain and
+suggest either upgrading or using  an environment variable to point to
+a more recent version of the required tool(s).
+
+Note that  `aclocal' is provided  by the `automake' package  on Linux,
+and that `libtoolize' is called `glibtoolize' on Darwin (OS X).
+
+
+For static builds which  don't use platform specific optimizations, no
+configure script is necessary at all; saying
+
+  make setup ansi
+  make
+
+should work on all platforms which have GNU make (or makepp).
+
+
+Similarly, a  build with  `cmake' can  be done  directly from  the git
+repository.

+Copyright 2005-2018 by
+Werner Lemberg and Detlef W�rkner.

+
+
+The makefile.os4 is for the AmigaOS4 SDK.  To use it, type
+"make -f makefile.os4", it produces a link library libft2_ppc.a.
+
+The makefile is for ppc-morphos-gcc-2.95.3-bin.tgz (gcc 2.95.3 hosted on
+68k-Amiga producing MorphOS-PPC-binaries from http://www.morphos.de).
+To use it, type "make assign", then "make"; it produces a link library
+libft2_ppc.a.
+
+The smakefile is a makefile for Amiga SAS/C 6.58 (no longer available,
+latest sold version was 6.50, updates can be found in Aminet).  It is
+based on the version found in the sourcecode of ttf.library 0.83b for
+FreeType 1.3.1 from Richard Griffith (ragriffi@sprynet.com,
+http://ragriffi.home.sprynet.com).
+
+You will also need the latest include files and amiga.lib from the
+Amiga web site (http://www.amiga.com/3.9/download/NDK3.9.lha) for
+AmigaOS 3.9; the generated code should work under AmigaOS 2.04 and up.
+
+To use it, call "smake assign" and then "smake" from the builds/amiga
+directory.  The results are:
+
+- A link library "ft2_680x0.lib" (where x depends on the setting of
+  the CPU entry in the smakefile) containing all FreeType2 parts
+  except of the init code, debugging code, and the system interface
+  code.
+
+- ftsystem.o, an object module containing the standard version of the
+  system interface code which uses fopen() fclose() fread() fseek()
+  ftell() malloc() realloc() and free() from lib:sc.lib (not pure).
+
+- ftsystempure.o, an object module containing the pure version of the
+  system interface code which uses Open() Close() Read() Seek()
+  ExamineFH() AsmAllocPooled() AsmFreePooled() etc.  This version can
+  be used in both normal programs and in Amiga run-time shared system
+  librarys (can be linked with lib:libinit.o, no copying of DATA and
+  BSS hunks for each OpenLibrary() necessary).  Source code is in
+  src/base/ftsystem.c.
+
+- ftdebug.o, an object module containing the standard version of the
+  debugging code which uses vprintf() and exit() (not pure).
+  Debugging can be turned on in FT:include/freetype/config/ftoption.h
+  and with FT_SetTraceLevel().
+
+- ftdebugpure.o, an object module containing the pure version of the
+  debugging code which uses KVPrintf() from lib:debug.lib and no
+  exit().  For debugging of Amiga run-time shared system libraries.
+  Source code is in src/base/ftdebug.c.
+
+- NO ftinit.o.  Because linking with a link library should result in
+  linking only the needed object modules in it, but standard
+  ftsystem.o would force ALL FreeType2 modules to be linked to your
+  program, I decided to use a different scheme: You must #include
+  FT:src/base/ftinit.c in your sourcecode and specify with #define
+  statements which modules you need.  See
+  include/freetype/config/ftmodule.h.
+
+
+To use in your own programs:
+
+- Insert the #define and #include statements from top of
+  include/freetype/config/ftmodule.h in your source code and
+  uncomment the #define statements for the FreeType2 modules you need.
+
+- You can use either PARAMETERS=REGISTER or PARAMETERS=STACK for
+  calling the FreeType2 functions, because the link library and the
+  object files are compiled with PARAMETERS=BOTH.
+
+- "smake assign" (assign "FT:" to the FreeType2 main directory).
+
+- Compile your program.
+
+- Link with either ftsystem.o or ftsystempure.o, if debugging enabled
+  with either ftdebug.o or (ftdebugpure.o and lib:debug.lib), and with
+  ft2_680x0.lib as link library.
+
+
+To adapt to other compilers:
+
+- The standard ANSI C maximum length of 31 significant characters in
+  identifiers is not enough for FreeType2.  Check if your compiler has
+  a minimum length of 40 significant characters or can be switched to
+  it.  "idlen=40" is the option for SAS/C.  Setting #define
+  HAVE_LIMIT_ON_IDENTS in an include file may also work (not tested).
+
+- Make sure that the include directory in builds/amiga is searched
+  before the normal FreeType2 include directory, so you are able to
+  replace problematic include files with your own version (same may be
+  useful for the src directory).
+
+- An example of how to replace/workaround a problematic include file
+  is include/freetype/config/ftconfig.h; it changes a #define that
+  would prevent SAS/C from generating XDEF's where it should do that and
+  then includes the standard FreeType2 include file.

+Compiling FreeType 2 with PureC compiler
+========================================
+
+[See below for a German version.]
+
+To compile FreeType 2 as a library the following changes must be applied:
+
+- All *.c files must start with an uppercase letter.
+  (In case GEMSCRIPT is available:
+  Simply drag the whole FreeType 2 directory to the file `FNames.SIC'.)
+
+- You have to change the INCLUDE directory in PureC's compiler options
+  to contain both the `INCLUDE' and `freetype2\include' directory.
+  Example:
+
+    INCLUDE;E:\freetype2\include
+
+- The file `freetype2/include/Ft2build.h' must be patched as follows to
+  include ATARI.H:
+
+    #ifndef FT2_BUILD_GENERIC_H_
+    #define FT2_BUILD_GENERIC_H_
+
+    #include "ATARI.H"
+
+
+
+Compilieren von FreeType 2 mit PureC
+====================================
+
+Um FreeType 2 als eine Bibliothek (library) zu compilieren, muss folgendes
+ge�ndert werden:
+
+- Alle *.c-files m�ssen mit einem GROSSBUCHSTABEN beginnen.
+  (Falls GEMSCRIPT zur Verf�gung steht:
+  Den kompletten Ordner freetype2 auf die Datei `FNames.SIC' draggen.)
+
+- In den Compiler-Optionen von PureC muss das INCLUDE directory auf INCLUDE
+  und freetype2\include verweisen. Z.B.:
+
+    INCLUDE;E:\freetype2\include
+
+- In der Datei freetype2/include/Ft2build.h muss zu Beginn
+  ein #include "ATARI.H" wie folgt eingef�gt werden:
+
+    #ifndef FT2_BUILD_GENERIC_H_
+    #define FT2_BUILD_GENERIC_H_
+
+    #include "ATARI.H"

+# Options
+# -------
+#
+#   IOS_PLATFORM = OS | SIMULATOR
+#
+#     This decides whether SDKS are selected from the `iPhoneOS.platform' or
+#     `iPhoneSimulator.platform' folders.
+#
+#     OS - the default, used to build for iPhone and iPad physical devices,
+#       which have an ARM architecture.
+#     SIMULATOR - used to build for the Simulator platforms, which have an
+#       x86 architecture.
+#
+#   CMAKE_IOS_DEVELOPER_ROOT = /path/to/platform/Developer folder
+#
+#     By default, this location is automatically chosen based on the
+#     IOS_PLATFORM value above.  If you manually set this variable, it
+#     overrides the default location and forces the use of a particular
+#     Developer Platform.
+#
+#   CMAKE_IOS_SDK_ROOT = /path/to/platform/Developer/SDKs/SDK folder
+#
+#     By default, this location is automatically chosen based on the
+#     CMAKE_IOS_DEVELOPER_ROOT value.  In this case it is always the most
+#     up-to-date SDK found in the CMAKE_IOS_DEVELOPER_ROOT path.  If you
+#     manually set this variable, it forces the use of a specific SDK
+#     version.

+This folder contains
+
+  * Makefile skeletons for Apple MPW (Macintosh's Programmer's Workshop)
+
+  * Python script to generate MPW makefile from skeleton
+
+  * Metrowerks CodeWarrior 9.0 project file in XML format
+
+------------------------------------------------------------
+
+1. What is this
+---------------
+
+Files in this directory are designed to build FreeType
+running on classic MacOS. To build FreeType running on
+Mac OS X, build as the system is UNIX.
+
+However, Mac OS X is most useful to manipulate files in
+vanilla FreeType to fit classic MacOS.
+
+The information about MacOS specific API is written in
+appendix of this document.
+
+2. Requirement
+--------------
+
+You can use MPW: a free-charged developer environment
+by Apple, or CodeWarrior: a commercial developer
+environment by Metrowerks. GCC for MPW and Symantec
+"Think C" are not tested at present.
+
+
+  2-1. Apple MPW
+  --------------
+
+  Following C compilers are tested:
+
+      m68k target:	Apple SC  8.9.0d3e1
+      ppc  target:	Apple MrC 5.0.0d3c1
+
+  The final MPW-GM (official release on 1999/Dec) is too
+  old and cannot compile FreeType, because bundled C
+  compilers cannot search header files in sub directories.
+  Updating by the final MPW-PR (pre-release on 2001/Feb)
+  is required.
+
+  Required files are downloadable from:
+
+      http://developer.apple.com/tools/mpw-tools/index.html
+
+  Also you can find documents how to update by MPW-PR.
+
+  Python is required to restore MPW makefiles from the
+  skeletons. Python bundled to Mac OS X is enough. For
+  classic MacOS, MacPython is available:
+
+      http://homepages.cwi.nl/~jack/macpython/
+
+  MPW requires all files are typed by resource fork.
+  ResEdit bundled to MPW is enough. In Mac OS X,
+  /Developer/Tools/SetFile of DevTool is useful to
+  manipulate from commandline.
+
+  2-2. Metrowerks CodeWarrior
+  ---------------------------
+
+  XML project file is generated and tested by
+  CodeWarrior 9.0.  Older versions are not tested
+  at all. At present, static library for ppc target
+  is available in the project file.
+
+
+3. How to build
+---------------
+
+  3-1. Apple MPW
+  --------------
+  Detailed building procedure by Apple MPW is
+  described in following.
+
+    3-1-1. Generate MPW makefiles from the skeletons
+    ------------------------------------------------
+
+    Here are 4 skeletons for following targets are
+    included.
+
+    - FreeType.m68k_far.make.txt
+      Ancient 32bit binary executable format for
+      m68k MacOS: System 6, with 32bit addressing
+      mode (far-pointer-model) So-called "Toolbox"
+      API is used.
+
+    - FreeType.m68k_cfm.make.txt
+      CFM binary executable format for m68k MacOS:
+      System 7. So-called "Toolbox" API is used.
+
+    - FreeType.ppc_classic.make.txt
+      CFM binary executable format for ppc MacOS:
+      System 7, MacOS 8, MacOS 9. So-called "Toolbox"
+      API is used.
+
+    - FreeType.ppc_carbon.make.txt
+      CFM binary executable format for ppc MacOS:
+      MacOS 9. Carbon API is used.
+
+    At present, static library is only supported,
+    although targets except of m68k_far are capable
+    to use shared library.
+
+    MPW makefile syntax uses 8bit characters. To keep
+    from violating them during version control, here
+    we store skeletons in pure ASCII format. You must
+    generate MPW makefile by Python script ascii2mpw.py.
+
+    In Mac OS X terminal, you can convert as:
+
+	python builds/mac/ascii2mpw.py \
+		< builds/mac/FreeType.m68k_far.make.txt \
+		> FreeType.m68k_far.make
+
+    The skeletons are designed to use in the top
+    directory where there are builds, include, src etc.
+    You must name the generated MPW makefile by removing
+    ".txt" from source skeleton name.
+
+    3-1-2. Add resource forks to related files
+    ------------------------------------------
+
+    MPW's Make and C compilers cannot recognize files
+    without resource fork. You have to add resource
+    fork to the files that MPW uses. In Mac OS X
+    terminal of the system, you can do as:
+
+	find . -name '*.[ch]' -exec \
+		/Developer/Tools/SetFile -a l -c "MPS " -t TEXT \{\} \;
+
+	find . -name '*.make' -exec \
+		/Developer/Tools/SetFile -a l -c "MPS " -t TEXT \{\} \;
+
+
+    3-1-3. Open MPW shell and build
+    -------------------------------
+
+    Open MPW shell and go to the top directory that
+    FreeType sources are extracted (MPW makefile must
+    be located in there), from "Set Directory" in
+    "Directory" menu.
+
+    Choose "Build" from "Build" menu, and type the
+    name of project by removing ".make" from MPW
+    makefile, as: FreeType.m68k_far
+
+    If building is successfully finished, you can find
+    built library in objs/ directory.
+
+
+  3-2. Metrowerks CodeWarrior
+  ---------------------------
+
+  Detailed building procedure by Metrowerks
+  CodeWarrior (CW) 9.0 is described in following.
+
+    3-2-1. Import XML project file
+    ------------------------------
+
+    CW XML project file is not ready for double-
+    click. Start CodeWarrior IDE, and choose
+    "Import project" in "File" menu. Choose XML
+    project file: builds/mac/ftlib.prj.xml.
+    In next, you will be asked where to save CW
+    native project file: you must choose
+    "builds/mac/ftlib.prj". The project file is
+    designed with relative path from there. After
+    CW native project file is generated, it is
+    automatically loaded, small project window
+    titled "ftlib.prj" is displayed.
+
+    3-2-2. Building
+    ---------------
+    Choose "Make" from "Project" menu. If building
+    is successfully finished, you can find built
+    library at objs/FreeTypeLib.
+
+4. TODO
+-------
+
+  4-1. All modules should be included
+  -----------------------------------
+
+  At present, MPW makefiles and CW project file are
+  just updated versions of these by Leonard. Some
+  modules are added after the last maintenance, they
+  are not included.
+
+  4-2. Working test with ftdemos
+  ------------------------------
+
+  At present, MPW makefiles and CW project file can
+  build FreeType for classic MacOS. But their working
+  behaviours are not tested at all. Building ftdemos
+  for classic MacOS and working test is required.
+
+  4-3. Porting Jam onto MPW
+  -------------------------
+
+  FreeType uses Jam (and FT-Jam) for unified cross-
+  platform building tool. At present, Jam is not ported
+  to MPW. To update classic MacOS support easily,
+  building by Jam is expected on MPW.
+
+
+APPENDIX I
+----------
+
+  A-1. Framework dependencies
+  ---------------------------
+
+  src/base/ftmac.c adds two Mac-specific features to
+  FreeType. These features are based on MacOS libraries.
+
+  * accessing resource-fork font
+  The fonts for classic MacOS store their graphical data
+  in resource forks which cannot be accessed via ANSI C
+  functions. FreeType2 provides functions to handle such
+  resource fork fonts, they are based on File Manager
+  framework of MacOS. In addition, HFS and HFS+ file
+  system driver of Linux is supported. Following
+  functions are for this purpose.
+
+    FT_New_Face_From_Resource()
+    FT_New_Face_From_FSSpec()
+    FT_New_Face_From_FSRef()
+
+  * resolving font name to font file
+  The font menu of MacOS application prefers font name
+  written in FOND resource than sfnt resource. FreeType2
+  provides functions to find font file by name in MacOS
+  application, they are based on QuickDraw Font Manager
+  and Apple Type Service framework of MacOS.
+
+    FT_GetFile_From_Mac_Name()
+    FT_GetFile_From_Mac_ATS_Name()
+
+  Working functions for each MacOS are summarized as
+  following.
+
+  upto MacOS 6:
+    not tested (you have to obtain MPW 2.x)
+
+  MacOS 7.x, 8.x, 9.x (without CarbonLib):
+    FT_GetFile_From_Mac_Name()
+    FT_New_Face_From_Resource()
+    FT_New_Face_From_FSSpec()
+
+  MacOS 9.x (with CarbonLib):
+    FT_GetFile_From_Mac_Name()
+    FT_New_Face_From_Resource()
+    FT_New_Face_From_FSSpec()
+    FT_New_Face_From_FSRef()
+
+  Mac OS X upto 10.4.x:
+    FT_GetFile_From_Mac_Name()     deprecated
+    FT_New_Face_From_FSSpec()      deprecated
+    FT_GetFile_From_Mac_ATS_Name() deprecated?
+    FT_New_Face_From_FSRef()
+
+  A-2. Deprecated Functions
+  -------------------------
+
+    A-2-1. FileManager
+    ------------------
+
+    For convenience to write MacOS application, ftmac.c
+    provides functions to specify a file by FSSpec and FSRef,
+    because the file identification pathname had ever been
+    unrecommended method in MacOS programming.
+
+    Toward to MacOS X 10.4 & 5, Carbon functions using FSSpec
+    datatype is noticed as deprecated, and recommended to
+    migrate to FSRef datatype. The big differences of FSRef
+    against FSSpec are explained in Apple TechNotes 2078.
+
+    http://developer.apple.com/technotes/tn2002/tn2078.html
+
+    - filename length: the max length of file
+    name of FSRef is 255 chars (it is limit of HFS+),
+    that of FSSpec is 31 chars (it is limit of HFS).
+
+    - filename encoding: FSSpec is localized by
+    legacy encoding for each language system,
+    FSRef is Unicode enabled.
+
+    A-2-2. FontManager
+    ------------------
+
+    Following functions receive QuickDraw fontname:
+
+      FT_GetFile_From_Mac_Name()
+
+    QuickDraw is deprecated and replaced by Quartz
+    since Mac OS X 10.4. They are still kept for
+    backward compatibility. By undefinition of
+    HAVE_QUICKDRAW in building, you can change these
+    functions to return FT_Err_Unimplemented always.
+
+    Replacement functions are added for migration.
+
+      FT_GetFile_From_Mac_ATS_Name()
+
+    They are usable on Mac OS X only. On older systems,
+    these functions return FT_Err_Unimplemented always.
+
+    The detailed incompatibilities and possibility
+    of FontManager emulation without QuickDraw is
+    explained in
+
+      http://www.gyve.org/~mpsuzuki/ats_benchmark.html
+
+  A-3. Framework Availabilities
+  -----------------------------
+
+  The framework of MacOS are often revised, especially
+  when new format of binary executable is introduced.
+  Following table is the minimum version of frameworks
+  to use functions used in FreeType2. The table is
+  extracted from MPW header files for assembly language.
+
+  *** NOTE ***
+  The conditional definition of available data type
+  in MPW compiler is insufficient. You can compile
+  program using FSRef data type for older systems
+  (MacOS 7, 8) that don't know FSRef data type.

+
+    (*)
+    In the "Classic": the original binary executable
+    format, these framework functions are directly
+    transformed to MacOS system call. Therefore, the
+    exact availability should be checked by running
+    system.
+
+    (**)
+    InterfaceLib is bundled to MacOS and its version
+    is usually equal to MacOS. There's no separate
+    update for InterfaceLib. It is supposed that
+    there's no InterfaceLib 9.x for m68k platforms.
+    In fact, these functions are FSRef dependent.
+
+    (***)
+    ATSUI framework is available on ATSUnicode 8.5 on
+    ppc Toolbox CFM, CarbonLib 1.0 too. But its base:
+    ATS font manager is not published in these versions.

+    Notes
+
+    Mac suitcase files can (and often do!) contain multiple fonts.  To
+    support this I use the face_index argument of FT_(Open|New)_Face()
+    functions, and pretend the suitcase file is a collection.
+
+    Warning: fbit and NFNT bitmap resources are not supported yet.  In old
+    sfnt fonts, bitmap glyph data for each size is stored in each `NFNT'
+    resources instead of the `bdat' table in the sfnt resource.  Therefore,
+    face->num_fixed_sizes is set to 0, because bitmap data in `NFNT'
+    resource is unavailable at present.
+
+    The Mac FOND support works roughly like this:
+
+    - Check whether the offered stream points to a Mac suitcase file.  This
+      is done by checking the file type: it has to be 'FFIL' or 'tfil'.  The
+      stream that gets passed to our init_face() routine is a stdio stream,
+      which isn't usable for us, since the FOND resources live in the
+      resource fork.  So we just grab the stream->pathname field.
+
+    - Read the FOND resource into memory, then check whether there is a
+      TrueType font and/or(!) a Type 1 font available.
+
+    - If there is a Type 1 font available (as a separate `LWFN' file), read
+      its data into memory, massage it slightly so it becomes PFB data, wrap
+      it into a memory stream, load the Type 1 driver and delegate the rest
+      of the work to it by calling FT_Open_Face().  (XXX TODO: after this
+      has been done, the kerning data from the FOND resource should be
+      appended to the face: On the Mac there are usually no AFM files
+      available.  However, this is tricky since we need to map Mac char
+      codes to ps glyph names to glyph ID's...)
+
+    - If there is a TrueType font (an `sfnt' resource), read it into memory,
+      wrap it into a memory stream, load the TrueType driver and delegate
+      the rest of the work to it, by calling FT_Open_Face().
+
+    - Some suitcase fonts (notably Onyx) might point the `LWFN' file to
+      itself, even though it doesn't contains `POST' resources.  To handle
+      this special case without opening the file an extra time, we just
+      ignore errors from the `LWFN' and fallback to the `sfnt' if both are
+      available.

+# These exist entirely to fool aclocal when bootstrapping libtool.
+#
+# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN),
+# which have later been changed to m4_define as they aren't part of the
+# exported API, or moved to Autoconf or Automake where they belong.
+#
+# The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
+# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
+# using a macro with the same name in our local m4/libtool.m4 it'll
+# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
+# and doesn't know about Autoconf macros at all.)
+#
+# So we provide this file, which has a silly filename so it's always
+# included after everything else.  This provides aclocal with the
+# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
+# because those macros already exist, or will be overwritten later.
+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
+#
+# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
+# Yes, that means every name once taken will need to remain here until
+# we give up compatibility with versions before 1.7, at which point
+# we need to keep only those names which we still refer to.
+
+# This is to help aclocal find these macros, as it can't see m4_define.

+	mmap private fixed at somewhere currently unmapped
+	mmap private fixed at somewhere already mapped
+	mmap shared not fixed
+	mmap shared fixed at somewhere currently unmapped
+	mmap shared fixed at somewhere already mapped
+   For private mappings, we should verify that changes cannot be read()
+   back from the file, nor mmap's back from the file at a different
+   address.  (There have been systems where private was not correctly
+   implemented like the infamous i386 svr4.0, and systems where the
+   VM page cache was not coherent with the file system buffer cache
+   like early versions of FreeBSD and possibly contemporary NetBSD.)
+   For shared mappings, we should conversely verify that changes get
+   propagated back to all the places they're supposed to be.
+
+   Grep wants private fixed already mapped.
+   The main things grep needs to know about mmap are:
+   * does it exist and is it safe to write into the mmap'd area
+   * how to use it (BSD variants)  */

+## ------ ##
+## Usage. ##
+## ------ ##
+
+# This file is a library for parsing options in your shell scripts along
+# with assorted other useful supporting features that you can make use
+# of too.
+#
+# For the simplest scripts you might need only:
+#
+#   #!/bin/sh
+#   . relative/path/to/funclib.sh
+#   . relative/path/to/options-parser
+#   scriptversion=1.0
+#   func_options ${1+"$@"}
+#   eval set dummy "$func_options_result"; shift
+#   ...rest of your script...
+#
+# In order for the '--version' option to work, you will need to have a
+# suitably formatted comment like the one at the top of this file
+# starting with '# Written by ' and ending with '# warranty; '.
+#
+# For '-h' and '--help' to work, you will also need a one line
+# description of your script's purpose in a comment directly above the
+# '# Written by ' line, like the one at the top of this file.
+#
+# The default options also support '--debug', which will turn on shell
+# execution tracing (see the comment above debug_cmd below for another
+# use), and '--verbose' and the func_verbose function to allow your script
+# to display verbose messages only when your user has specified
+# '--verbose'.
+#
+# After sourcing this file, you can plug processing for additional
+# options by amending the variables from the 'Configuration' section
+# below, and following the instructions in the 'Option parsing'
+# section further down.
+
+## -------------- ##
+## Configuration. ##
+## -------------- ##
+
+# You should override these variables in your script after sourcing this
+# file so that they reflect the customisations you have added to the
+# option parser.
+
+# The usage line for option parsing errors and the start of '-h' and
+# '--help' output messages. You can embed shell variables for delayed

+# expanded when the contents are evaled.

+<h1>
+  FreeType&nbsp;2 Project Files for VS.NET&nbsp;2005
+  (Pocket PC)
+</h1>
+
+<p>This directory contains project files for Visual C++, named
+<tt>freetype.vcproj</tt>, and Visual Studio, called <tt>freetype.sln</tt> for
+the following targets:
+
+<ul>
+  <li>PPC/SP 2003 (Pocket PC 2003)</li>
+  <li>PPC/SP WM5 (Windows Mobile 5)</li>
+  <li>PPC/SP WM6 (Windows Mobile 6)</li>
+</ul>
+
+It compiles the following libraries from the FreeType 2.9.1 sources:</p>
+
+<ul>
+  <pre>
+    freetype291.lib     - release build; single threaded
+    freetype291_D.lib   - debug build;   single threaded
+    freetype291MT.lib   - release build; multi-threaded
+    freetype291MT_D.lib - debug build;   multi-threaded</pre>
+</ul>
+
+<p>Be sure to extract the files with the Windows (CR+LF) line endings.  ZIP
+archives are already stored this way, so no further action is required.  If
+you use some <tt>.tar.*z</tt> archives, be sure to configure your extracting
+tool to convert the line endings.  For example, with <a
+href="http://www.winzip.com">WinZip</a>, you should activate the <em>TAR
+file smart CR/LF Conversion</em> option.  Alternatively, you may consider
+using the <tt>unix2dos</tt> or <tt>u2d</tt> utilities that are floating
+around, which specifically deal with this particular problem.
+
+<p>Build directories are placed in the top-level <tt>objs</tt>
+directory.</p>

+<h1>
+  FreeType&nbsp;2 Project Files for VS.NET&nbsp;2008
+  (Pocket PC)
+</h1>
+
+<p>This directory contains project files for Visual C++, named
+<tt>freetype.dsp</tt>, and Visual Studio, called <tt>freetype.sln</tt> for
+the following targets:
+
+<ul>
+  <li>PPC/SP 2003 (Pocket PC 2003)</li>
+  <li>PPC/SP WM5 (Windows Mobile 5)</li>
+  <li>PPC/SP WM6 (Windows Mobile 6)</li>
+</ul>
+
+It compiles the following libraries from the FreeType 2.9.1 sources:</p>
+
+<ul>
+  <pre>
+    freetype291.lib     - release build; single threaded
+    freetype291_D.lib   - debug build;   single threaded
+    freetype291MT.lib   - release build; multi-threaded
+    freetype291MT_D.lib - debug build;   multi-threaded</pre>
+</ul>
+
+<p>Be sure to extract the files with the Windows (CR+LF) line endings.  ZIP
+archives are already stored this way, so no further action is required.  If
+you use some <tt>.tar.*z</tt> archives, be sure to configure your extracting
+tool to convert the line endings.  For example, with <a
+href="http://www.winzip.com">WinZip</a>, you should activate the <em>TAR
+file smart CR/LF Conversion</em> option.  Alternatively, you may consider
+using the <tt>unix2dos</tt> or <tt>u2d</tt> utilities that are floating
+around, which specifically deal with this particular problem.
+
+<p>Build directories are placed in the top-level <tt>objs</tt>
+directory.</p>

+<h1>
+  FreeType&nbsp;2 Project Files for VS.NET&nbsp;2005
+</h1>
+
+<p>This directory contains project files for Visual C++, named
+<tt>freetype.vcproj</tt>, and Visual Studio, called <tt>freetype.sln</tt>.  It
+compiles the following libraries from the FreeType 2.9.1 sources:</p>
+
+<ul>
+  <pre>
+    freetype291.lib     - release build; single threaded
+    freetype291_D.lib   - debug build;   single threaded
+    freetype291MT.lib   - release build; multi-threaded
+    freetype291MT_D.lib - debug build;   multi-threaded</pre>
+</ul>
+
+<p>Be sure to extract the files with the Windows (CR+LF) line endings.  ZIP
+archives are already stored this way, so no further action is required.  If
+you use some <tt>.tar.*z</tt> archives, be sure to configure your extracting
+tool to convert the line endings.  For example, with <a
+href="http://www.winzip.com">WinZip</a>, you should activate the <em>TAR
+file smart CR/LF Conversion</em> option.  Alternatively, you may consider
+using the <tt>unix2dos</tt> or <tt>u2d</tt> utilities that are floating
+around, which specifically deal with this particular problem.
+
+<p>Build directories are placed in the top-level <tt>objs</tt>
+directory.</p>

+<h1>
+  FreeType&nbsp;2 Project Files for VS.NET&nbsp;2008
+</h1>
+
+<p>This directory contains project files for Visual C++, named
+<tt>freetype.vcproj</tt>, and Visual Studio, called <tt>freetype.sln</tt>.  It
+compiles the following libraries from the FreeType 2.9.1 sources:</p>
+
+<ul>
+  <pre>
+    freetype291.lib     - release build; single threaded
+    freetype291_D.lib   - debug build;   single threaded
+    freetype291MT.lib   - release build; multi-threaded
+    freetype291MT_D.lib - debug build;   multi-threaded</pre>
+</ul>
+
+<p>Be sure to extract the files with the Windows (CR+LF) line endings.  ZIP
+archives are already stored this way, so no further action is required.  If
+you use some <tt>.tar.*z</tt> archives, be sure to configure your extracting
+tool to convert the line endings.  For example, with <a
+href="http://www.winzip.com">WinZip</a>, you should activate the <em>TAR
+file smart CR/LF Conversion</em> option.  Alternatively, you may consider
+using the <tt>unix2dos</tt> or <tt>u2d</tt> utilities that are floating
+around, which specifically deal with this particular problem.
+
+<p>Build directories are placed in the top-level <tt>objs</tt>
+directory.</p>

+<h1>
+  FreeType&nbsp;2 Project Files for Visual&nbsp;C++&nbsp;2010 or newer
+</h1>
+
+<p>This directory contains solution and project files for
+Visual&nbsp;C++&nbsp;2010 or newer, named <tt>freetype.sln</tt>,
+and <tt>freetype.vcxproj</tt>.  It compiles the following libraries
+from the FreeType 2.9.1 sources:</p>
+
+<ul>
+  <li>freetype.dll using 'Release' or 'Debug' configurations</li>
+  <li>freetype.lib using 'Release Static' or 'Debug Static' configurations</li>
+</ul>
+
+<p>Both Win32 and x64 builds are supported.  Build directories and target
+files are placed in the top-level <tt>objs</tt> directory.</p>
+
+<p>Customization of the FreeType library is done by editing the
+<tt>ftoption.h</tt> header file in the top-level <tt>devel</tt> path.
+Alternatively, you may copy the file to another directory and change the
+include directory in <tt>freetype.users.props</tt>.</p>
+
+<p>To configure library dependencies like <em>zlib</em> and <em>libpng</em>,
+edit the <tt>freetype.users.props</tt> file in this directory.  It also
+simplifies automated (command-line) builds using <a
+href="http://msdn.microsoft.com/library/dd393574%28v=vs.100%29.aspx">msbuild</a>.</p>
+
+<p>To link your executable with FreeType DLL, you may want to define
+FT2_DLLIMPORT so that the imported functions are appropriately
+attributed with <tt>dllimport<tt>.</p>

+<h1>
+  FreeType&nbsp;2 Project Files for Visual&nbsp;C++ and VS.NET&nbsp;2005
+</h1>
+
+<p>This directory contains project files for Visual C++, named
+<tt>freetype.dsp</tt>, and Visual Studio, called <tt>freetype.sln</tt>.  It
+compiles the following libraries from the FreeType 2.9.1 sources:</p>
+
+<ul>
+  <pre>
+    freetype291.lib     - release build; single threaded
+    freetype291_D.lib   - debug build;   single threaded
+    freetype291MT.lib   - release build; multi-threaded
+    freetype291MT_D.lib - debug build;   multi-threaded</pre>
+</ul>
+
+<p>Be sure to extract the files with the Windows (CR+LF) line endings.  ZIP
+archives are already stored this way, so no further action is required.  If
+you use some <tt>.tar.*z</tt> archives, be sure to configure your extracting
+tool to convert the line endings.  For example, with <a
+href="http://www.winzip.com">WinZip</a>, you should activate the <em>TAR
+file smart CR/LF Conversion</em> option.  Alternatively, you may consider
+using the <tt>unix2dos</tt> or <tt>u2d</tt> utilities that are floating
+around, which specifically deal with this particular problem.
+
+<p>Build directories are placed in the top-level <tt>objs</tt>
+directory.</p>

+<h1>
+  FreeType&nbsp;2 Project Files for Visual&nbsp;C++ and VS.NET&nbsp;2005
+  (Pocket PC)
+</h1>
+
+<p>This directory contains project files for Visual C++, named
+<tt>freetype.dsp</tt>, and Visual Studio, called <tt>freetype.sln</tt> for
+the following targets:
+
+<ul>
+  <li>PPC/SP 2003 (Pocket PC 2003)</li>
+  <li>PPC/SP WM5 (Windows Mobile 5)</li>
+  <li>PPC/SP WM6 (Windows Mobile 6)</li>
+</ul>
+
+It compiles the following libraries from the FreeType 2.9.1 sources:</p>
+
+<ul>
+  <pre>
+    freetype291.lib     - release build; single threaded
+    freetype291_D.lib   - debug build;   single threaded
+    freetype291MT.lib   - release build; multi-threaded
+    freetype291MT_D.lib - debug build;   multi-threaded</pre>
+</ul>
+
+<p>Be sure to extract the files with the Windows (CR+LF) line endings.  ZIP
+archives are already stored this way, so no further action is required.  If
+you use some <tt>.tar.*z</tt> archives, be sure to configure your extracting
+tool to convert the line endings.  For example, with <a
+href="http://www.winzip.com">WinZip</a>, you should activate the <em>TAR
+file smart CR/LF Conversion</em> option.  Alternatively, you may consider
+using the <tt>unix2dos</tt> or <tt>u2d</tt> utilities that are floating
+around, which specifically deal with this particular problem.
+
+<p>Build directories are placed in the top-level <tt>objs</tt>
+directory.</p>

+      correctly (bug introduced in version 2.9).
+
+    - CVE-2018-6942: Older  FreeType versions  can crash  with certain
+      malformed variation fonts.
+
+        http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-6942
+
+
+  II. MISCELLANEOUS
+
+    - Bug fix: Multiple calls to `FT_Get_MM_Var' returned garbage.
+
+    - The base  extensions `ftlcdfil' and  `ftfntfmt' are now  part of
+      the  base  module  (and  thus no  longer  configurable  in  file
+      `modules.cfg').
+
+    - Emboldening of bitmaps didn't work correctly sometimes,  showing
+      various artifacts (bug introduced in version 2.8.1).
+
+    - Use  of  the `freetype-config'  script  to  get compilation  and
+      linking  options   is  deprecated   since  it   doesn't  support
+      cross-compiling, among other  deficiencies.  Instead, you should
+      use the `pkg-config' interface.
+
+      The `configure'  script no longer installs  `freetype-config' by
+      default.  For  backwards compatibility,  a new  configure option
+      `--enable-freetype-config'   is  provided   that  reverts   this
+      decision.
+
+    - The auto-hinter script ranges have  been updated for Unicode 11.
+      No support  for new scripts  have been added, however,  with the
+      exception of Georgian Mtavruli.
+
+    - Support for cmake has been improved.
+
+    - The next  release will  remove support for  Position Independent
+      Code  as  needed  by  systems that  prohibit  automatic  address
+      fixups, such  as BREW.  [Compilation with  modern compilers that
+      use flags like `-fPIC' or `-fPIE' is not affected.]
+
+
+======================================================================
+
+CHANGES BETWEEN 2.8.1 and 2.9
+
+  I. IMPORTANT BUG FIXES
+
+    - Advance width values of variation fonts were often wrong.
+
+    - More fixes for variation font support; you should update to this
+      version if you want to support them.
+
+
+  II. IMPORTANT CHANGES
+
+    - As a GSoC project, Ewald Hew extended the new (Adobe) CFF engine
+      to  handle  Type  1  fonts  also,  thus  greatly  improving  the
+      rendering of  this format.   This is the  new default.   The old
+      engine   is  still   available   if   the  configuration   macro
+      `T1_CONFIG_OPTION_OLD_ENGINE'    gets    defined;   using    the
+      `hinting-engine' property  of the `type1' driver  module you can
+      then switch between the two engines.
+
+    - A new function,  `FT_Set_Named_Instance', can be used  to set or
+      change the current named instance.
+
+    - Starting  with   this  FreeType  version,   resetting  variation
+      coordinates  will   return  to  the  currently   selected  named
+      instance.  Previously, FreeType returned to the base font (i.e.,
+      no instance set).
+
+
+  III. MISCELLANEOUS
+
+    - The `face_flags' field of the `FT_Face' structure has a new bit,
+      `FT_FACE_FLAG_VARIATION', which  is set if a  variation font has
+      been      altered      with      `FT_Set_MM_Design_Coordinates',
+      `FT_Set_Var_Design_Coordinates',                              or
+      `FT_Set_Var_Blend_Coordinates'.
+
+    - If  the  current  face  is  a  named  instance,  the  new  macro
+      `FT_IS_NAMED_INSTANCE' returns true.
+
+    - `FT_IS_VARIATION' is  a new macro  that returns true  whenever a
+      face object has  been altered by `FT_Set_MM_Design_Coordinates',
+      `FT_Set_Var_Design_Coordinates',                              or
+      `FT_Set_Var_Blend_Coordinates'.
+
+    - Changing  the  design  coordinates  of  a  variation  font  with
+      `FT_Set_Var_Design_Coordinates'                               or
+      `FT_Set_Var_Blend_Coordinates'  does  not  influence  the  named
+      instance index value (only `FT_Set_Named_Instance' does that).
+
+    - Special PostScript  names for named instances  are only returned
+      if the  named instance is set  with `FT_Set_Named_Instance' (and
+      the font  has corresponding  entries in  its `fvar'  table).  If
+      `FT_IS_VARIATION'  returns  true,  the  algorithmically  derived
+      PostScript name is provided, not  looking up special entries for
+      named instances.
+
+    - A new function  `FT_Done_MM_Var' is provided to  free the memory
+      returned in a call to `FT_Get_MM_Var'.
+
+    - On  platforms  using  the   `configure'  script,  the  installed
+      `ftoption.h' file  now correctly reflects  configuration options
+      like `--with-harfbuzz'.
+
+    - Better  support to  build FreeType  as  a DLL  on Windows  using
+      Visual C.
+
+    - All data specific to driver modules is now collected in a single
+      file,      `FT_DRIVER_H'.      Consequently,      the     macros
+      `FT_AUTOHINTER_H',   `FT_CFF_DRIVER_H',  `FT_TRUETYPE_DRIVER_H',
+      and `FT_PCF_DRIVER_H' still work but are deprecated.
+
+    - Some fuzzer fixes to better reject malformed fonts.
+
+    - The `ftbench' demo program has a new test for opening a new face
+      and loading some glyphs.
+
+    - The `ftbench' demo program has a  new option `-j' to specify the
+      last glyph index to be used in the tests.
+
+    - The  `ftgrid' demo  program has  a new  option `-n'  to suppress
+      display of named instances of variation fonts.
+
+    - The `ttdebug' demo program can now  show a stack trace (key `K')
+      and switch  between hexadecimal and decimal  display of integers
+      (key `I').
+
+
+======================================================================
+
+CHANGES BETWEEN 2.8 and 2.8.1
+
+  I. IMPORTANT BUG FIXES
+
+    - B/W  hinting   of  TrueType   fonts  didn't  work   properly  if
+      interpreter version 38 or 40 was selected.
+
+    - Some severe  problems within the handling  of TrueType Variation
+      Fonts were found and fixed.
+
+    - Function `FT_Set_Var_Design_Coordinates' didn't correctly handle
+      the case with less input coordinates than axes.
+
+
+  II. IMPORTANT CHANGES
+
+    - By  default,  FreeType  now offers  high  quality  LCD-optimized
+      output without  resorting to ClearType techniques  of resolution
+      tripling and  filtering.  In  this method, called  Harmony, each
+      color channel  is generated separately after  shifting the glyph
+      outline, capitalizing  on the fact  that the color grids  on LCD
+      panels  are shifted  by  a third  of a  pixel.   This output  is
+      indistinguishable from ClearType with a light 3-tap filter.
+
+
+  III. MISCELLANEOUS
+
+    - Using the  new function `FT_Get_Var_Axis_Flags',  an application
+      can access the `flags' field  of a variation axis (introduced in
+      OpenType version 1.8.2)
+
+    - More sanity checks.
+
+    - The  internal representation  of buffers  for LCD  rendering has
+      changed (to be more precise, the amount of padding gets computed
+      differently).  Applications  that use  the FreeType API  are not
+      affected.
+
+    - To  reset all  design axis  values of  a variation  font to  its
+      default values you can now say
+
+        error = FT_Set_Var_Design_Coordinates( face, 0, NULL );
+
+      This  also works  with functions  `FT_Set_MM_Design_Coordinates'
+      and `FT_Set_MM_Blend_Coordinates'.
+
+    - FreeType  now synthesizes  a  missing Unicode  cmap for  (older)
+      TrueType fonts also if glyph names are available.
+
+    - FreeType  has  improved  handling   of  BDF  fonts  without  the
+      `POINT_SIZE', `RESOLUTION_X', or  `RESOLUTION_Y' properties; the
+      library now  uses the values of  the `SIZE' keyword if  they are
+      missing.   Previously,   `SIZE'  was  completely   ignored,  and
+      FreeType used heuristic values instead.
+
+    - Multiple calls to `FT_Bitmap_Convert' do work now as advertised.
+      Previously,  they failed with an assertion error if there was an
+      empty bitmap between non-empty ones.
+
+    - The warping option  has moved  from `light'  to `normal' hinting
+      where  it replaces  the original hinting algorithm.  The `light'
+      mode is now always void of any hinting in x-direction.
+
+    - 16bit  compiler  support is  now  officially  ended.  We  didn't
+      provide any maintenance  since many years,  and given that there
+      were no error  or problem reports either it seems  that it is no
+      longer needed.
+
+    - The `ftgrid'  demo program  can now toggle  the display  of grid
+      lines with the `G' key.
+
+    - The `ftgrid' demo  program can toggle a different  set of colors
+      (suitable to color-blind people) with the `C' key.
+
+    - The `ftgrid'  demo program  now supports  the `-e'  command line
+      option to select a cmap.
+
+    - The `ftdump' demo program has a  new command line option `-t' to
+      output the SFNT table list.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.7.1 and 2.8
+
+  I. IMPORTANT CHANGES
+
+    - Support for OpenType Variation Fonts is now complete.   The last
+      missing part was handling the `VVAR' and `MVAR' tables, which is
+      available with this release.
+
+    - A new  function `FT_Face_Properties' allows the  control of some
+      module  and   library  properties  per  font.    Currently,  the
+      following properties can be  handled: stem darkening, LCD filter
+      weights, and the random seed for the `random' CFF operator.
+
+    - The PCF change to show more `colourful' family names (introduced
+      in version 2.7.1) was too radical; it can now be configured with
+      PCF_CONFIG_OPTION_LONG_FAMILY_NAMES   at   compile   time.    If
+      activated, it can  be switched off at run time  with the new pcf
+      property  `no-long-family-names'.  If  the `FREETYPE_PROPERTIES'
+      environment variable is available, you can say
+
+        FREETYPE_PROPERTIES=pcf:no-long-family-names=1
+
+    - Support  for  the  following  scripts  has  been  added  to  the
+      auto-hinter.
+
+        Adlam, Avestan, Bamum, Buhid, Carian, Chakma, Coptic, Cypriot,
+        Deseret, Glagolitic, Gothic, Kayah, Lisu, N'Ko, Ol Chiki, Old
+        Turkic, Osage, Osmanya, Saurashtra, Shavian, Sundanese, Tai
+        Viet, Tifinagh, Unified Canadian Syllabics, Vai
+
+
+  II. IMPORTANT BUG FIXES
+
+    - `Light' auto-hinting  mode no  longer uses TrueType  metrics for
+      TrueType  fonts.   This bug  was  introduced  in version  2.4.6,
+      causing   horizontal  scaling   also.    Almost  all   GNU/Linux
+      distributions (with Fedora as  a notable exception) disabled the
+      corresponding patch for good reasons; chances are thus high that
+      you won't notice a difference.
+
+      If  optical backward  compatibility for  legacy applications  is
+      necessary, you might enable the AF_CONFIG_OPTION_TT_SIZE_METRICS
+      configuration option.   However, it  is strongly  recommended to
+      avoid that, adjusting font sizes instead.
+
+    - Global size  metrics values  in the  `FT_Size_Metrics' structure
+      can be  different for TrueType  fonts.  Reason is that  in older
+      FreeType  versions  the  metrics  were  rounded  differently  to
+      integer pixels compared  to all other font  formats, yielding an
+      inconsistent behaviour if you used non-native hinting.  Starting
+      with this  version, global size  metrics for TrueType  fonts are
+      handled the same as other  font formats: `ascender' gets rounded
+      up,  `descender'  gets  rounded  down,  `height'  gets  normally
+      rounded, and `max_advance' gets normally rounded, too.
+
+      If you need more precise values of (global) ascender, descender,
+      height, or  `max_advance', please take the  corresponding values
+      from the `FT_Face' structure and scale them manually.
+
+    - If a TrueType font gets loaded with FT_LOAD_NO_HINTING, FreeType
+      now scales  the font linearly  again (bug introduced  in version
+      2.4.6).
+
+    - CVE-2017-8105,  CVE-2017-8287:  Older   FreeType  versions  have
+      out-of-bounds  writes  caused  by  heap-based  buffer  overflows
+      related to Type 1 fonts.
+
+        https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-8105
+        https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-8287
+
+
+  III. MISCELLANEOUS
+
+    - A  new function  `FT_Set_Default_Properties' has  been added  to
+      parse    the    `FREETYPE_PROPERTIES'    environment    variable
+      (previously, it  was internal only).   `FT_Init_FreeType' always
+      call this  function, but  `FT_New_Library' does not  (similar to
+      `FT_Add_Default_Modules').
+
+    - To be in sync with OpenType version 1.7 and newer, macros
+
+        FT_PARAM_TAG_IGNORE_PREFERRED_FAMILY,
+        FT_PARAM_TAG_IGNORE_PREFERRED_SUBFAMILY,
+        TT_NAME_ID_PREFERRED_FAMILY
+        TT_NAME_ID_PREFERRED_SUBFAMILY
+
+      are renamed to
+
+        FT_PARAM_TAG_IGNORE_TYPOGRAPHIC_FAMILY,
+        FT_PARAM_TAG_IGNORE_TYPOGRAPHIC_SUBFAMILY,
+        TT_NAME_ID_TYPOGRAPHIC_FAMILY
+        TT_NAME_ID_TYPOGRAPHIC_SUBFAMILY
+
+      The old macro names are deprecated (but still available).
+
+    - Support for SFNT `name' tables has been improved.
+
+      . Format  1 `name' tables  are now supported.  Use  new function
+        `FT_Get_Sfnt_LangTag' to access associated language tags.
+
+      . Language, encoding, and name IDs have been updated to OpenType
+        version 1.8.1.
+
+    - The new CFF  engine now handles the `random'  operator.  All CFF
+      opcodes are now supported.
+
+    - The CFF module  has a new property `random-seed'  to control the
+      pseudo-random number generation for the `random' operator.
+
+    - The `freetype-config' script is now a wrapper of `pkg-config' if
+      this program is available in the path.
+
+    - FT_LOAD_TARGET_LCD  is now  a  variant of  FT_LOAD_TARGET_LIGHT;
+      this should provide better rendering results.
+
+    - A mode to display  light auto-hinting with  subpixel positioning
+      has been added to `ftdiff'.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.7 and 2.7.1
+
+  I. IMPORTANT CHANGES
+
+    - Support for the new CFF2 font format as introduced with OpenType
+      1.8 has been contributed by Dave Arnolds from Adobe.
+
+    - Preliminary support for variation fonts as specified in OpenType
+      1.8 (in addition to the  already existing support for Adobe's MM
+      and Apple's  GX formats).  Dave Arnolds  contributed handling of
+      advance  width change  variation;  more will  come  in the  next
+      version.
+
+
+  II. IMPORTANT BUG FIXES
+
+    - Handling of  raw CID fonts was partially  broken (bug introduced
+      in 2.6.4).
+
+    - CVE-2016-10328:  Older  FreeType versions had  an  out-of-bounds
+      write caused by a heap-based  buffer overflow related to the CFF
+      fonts.
+
+        https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2016-10328
+
+
+  III. MISCELLANEOUS
+
+    - Some limits for TrueType  bytecode execution have been tightened
+      to  speed   up  FreeType's  handling  of   malformed  fonts,  in
+      particular to quickly abort endless loops.
+
+      - The  number of  twilight points  can no  longer be  set to  an
+        arbitrarily large value.
+
+      - The total number of jump  opcode instructions (like JMPR) with
+        negative arguments  is dynamically restricted; the  same holds
+        for the total number of iterations in LOOPCALL opcodes.
+
+      The dynamic limits are based on  the number of points in a glyph
+      and the number of CVT entries.  Please report if you encounter a
+      font where the selected values are not adequate.
+
+    - PCF family names are made more `colourful'; they now include the
+      foundry  and information  whether they contain  wide characters.
+      For example,  you no longer get `Fixed' but  rather `Sony Fixed'
+      or `Misc Fixed Wide'.
+
+    - A new  function `FT_Get_Var_Blend_Coordinates'  (with its  alias
+      name  `FT_Get_MM_Blend_Coordinates') to retrieve the  normalized
+      blend  coordinates of the currently  selected variation instance
+      has been added to the Multiple Masters interface.
+
+    - A new  function `FT_Get_Var_Design_Coordinates' to  retrieve the
+      design coordinates of the  currently selected variation instance
+      has been added to the Multiple Masters interface.
+
+    - A new load flag `FT_LOAD_BITMAP_METRICS_ONLY' to retrieve bitmap
+      information without loading the (embedded) bitmap itself.
+
+    - Retrieving   advance   widths   from   bitmap   strikes   (using
+      `FT_Get_Advance' and `FT_Get_Advances') have been sped up.
+
+    - The  usual round  of  fuzzer fixes  to  better reject  malformed
+      fonts.
+
+    - The `ftmulti' demo program can now switch engines with key `H'.
+
+    - The  `ftstring'  demo  program   can  now  show  some  built-in,
+      non-latin sample strings (to be selected with the TAB key).
+
+    - The  `ftview'  demo program  can  now  switch between  a  font's
+      charmaps using the TAB key.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.6.5 and 2.7
+
+  I. IMPORTANT CHANGES
+
+    - As announced earlier, the 2.7.x series now uses the new subpixel
+      hinting  mode as  the  default, emulating  a  modern version  of
+      ClearType.
+
+      This change inevitably leads to different rendering results, and
+      you   might   change   the   `TT_CONFIG_OPTION_SUBPIXEL_HINTING'
+      configuration option to  adapt it to your taste (or  use the new
+      `FREETYPE_PROPERTIES'    environment    variable).    See    the
+      corresponding entry  below for  version 2.6.4, which  gives more
+      information.
+
+    - A new option  `FT_CONFIG_OPTION_ENVIRONMENT_PROPERTIES' has been
+      introduced.   If  set (which  is  the  default), an  environment
+      variable  `FREETYPE_PROPERTIES' can  be used  to control  driver
+      properties.  Example:
+
+        FREETYPE_PROPERTIES=truetype:interpreter-version=35 \
+                            cff:no-stem-darkening=1 \
+                            autofitter:warping=1
+
+      This allows to select, say, the subpixel hinting mode at runtime
+      for a given application.  See file `ftoption.h' for more.
+
+
+  II. IMPORTANT BUG FIXES
+
+    - After  loading a  named instance  of  a GX  variation font,  the
+      `face_index'  value  in  the returned  `FT_Face'  structure  now
+      correctly holds the named instance  index in the upper 16bits as
+      documented.
+
+
+  III. MISCELLANEOUS
+
+    - A new macro `FT_IS_NAMED_INSTANCE' to  test whether a given face
+      is a named instance.
+
+    - More fixes to GX font handling.
+
+    - Apple's   `GETVARIATION'  bytecode   operator  (needed   for  GX
+      variation font support) has been implemented.
+
+    - Another round  of fuzzer fixes,  mainly to reject  invalid fonts
+      faster.
+
+    - Handling of raw CID fonts  was broken (bug introduced in version
+      2.6.4).
+
+    - The smooth rasterizer has been streamlined  to make it faster by
+      approx. 20%.
+
+    - The `ftgrid'  demo program now  understands command  line option
+      `-d' to give start-up design coordinates.
+
+    - The `ftdump' demo program has  a new command line option `-p' to
+      dump TrueType bytecode instructions.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.6.4 and 2.6.5
+
+  I. IMPORTANT BUG FIXES
+
+    - Compilation works again  on Mac OS X (bug introduced  in version
+      2.6.4).
+
+
+  II. IMPORTANT CHANGES
+
+    - The new  subpixel hinting  mode is now  disabled by  default; it
+      will  be enabled  by default  in the  forthcoming 2.7.x  series.
+      Main reason for reverting this feature is the principle of least
+      surprise: a  sudden change in  appearance of all fonts  (even if
+      the rendering improves  for almost all recent  fonts) should not
+      be expected in a new micro version of a series.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.6.3 and 2.6.4
+
+  I. IMPORTANT CHANGES
+
+    - A new  subpixel hinting  mode has  been contributed  by Nikolaus
+      Waxweiler, which is now the  default rendering mode for TrueType
+      fonts.  It implements  (almost everything of) version  40 of the
+      bytecode engine.
+
+      The existing code  base in FreeType (the  `Infinality code') was
+      stripped to the bare minimum  and all configurability removed in
+      the  name  of speed  and  simplicity.   The configurability  was
+      mainly aimed  at legacy  fonts like Arial,  Times New  Roman, or
+      Courier.  [Legacy fonts are fonts  that modify vertical stems to
+      achieve clean black-and-white bitmaps.]  The new mode focuses on
+      applying a minimal set of rules to all fonts indiscriminately so
+      that modern and web fonts  render well while legacy fonts render
+      okay.
+
+      Activation  of the  subpixel hinting  support can  be controlled
+      with   the   `TT_CONFIG_OPTION_SUBPIXEL_HINTING'   configuration
+      option  at compile  time: If  set to  value 1,  you get  the old
+      Infinality  mode  (which  was  never  the  default  due  to  its
+      slowness).  Value 2 activates the new subpixel hinting mode, and
+      value 3 activates both.  The default is value 2.
+
+      At run time,  you can select the subpixel hinting  mode with the
+      `interpreter-version'  property (provided  you have  compiled in
+      the corresponding hinting mode); see `ftttdrv.h' for more.
+
+    - Support  for  the  following  scripts  has  been  added  to  the
+      auto-hinter.
+
+        Armenian, Cherokee, Ethiopic, Georgian, Gujarati, Gurmukhi,
+        Malayalam, Sinhala, Tamil
+
+
+  II. MISCELLANEOUS
+
+    - Type 42 fonts as created by LilyPond are now supported.
+
+    - Minor rendering improvements in the auto-hinter.
+
+    - For experimental  reasons, the old  CFF engine now  supports all
+      CFF operators except `random', including the deprecated Multiple
+      Masters  instructions.  This  allows the  display of  fonts like
+      `ITCGaramondMM-It.otf' (without font variations, though).
+
+    - Another round of fixes to improve handling of invalid fonts.
+
+    - The `ftgrid' demo program now displays the rendered pixels also;
+      this can be switched off with the `b' key.  Selection of various
+      LCD filtering modes can be done with the `L' key.
+
+    - The demo programs  have been extended to allow  selection of all
+      available TrueType bytecode engines.
+
+    - A very early beta version of a new, Qt based demo program called
+      `ftinspect'  is  part  of  the   source  code  bundle;  it  will
+      eventually supersede  the other  demo programs.   Currently, you
+      have to compile  it manually with `qmake; make';  note that many
+      features are still missing.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.6.2 and 2.6.3
+
+  I. IMPORTANT CHANGES
+
+    - Khmer,  Myanmar, Bengali,  and Kannada  script support  has been
+      added to the auto-hinter.
+
+
+  II. MISCELLANEOUS
+
+    - Better  support of  Indic  scripts like  Devanagari  by using  a
+      top-to-bottom hinting flow.
+
+    - All  FreeType macros  starting  with two  underscores have  been
+      renamed to  avoid a violation of  both the C and  C++ standards.
+      Example: Header  macros of the  form `__FOO_H__' are  now called
+      `FOO_H_'.  In most cases,  this should be completely transparent
+      to the user.   The exception to this  is `__FTERRORS_H__', which
+      must be  sometimes undefined by  the user to get  FreeType error
+      strings:  Both this  form and  the new  `FTERRORS_H_' macro  are
+      accepted for backward compatibility.
+
+    - Minor improvements mainly to the Type 1 driver.
+
+    - The  new CFF  engine now  supports all  Type 2  operators except
+      `random'.
+
+    - The macro `_STANDALONE_', used for  compiling the B/W and smooth
+      rasterizers  as   stand-alone  modules,  has  been   renamed  to
+      `STANDALONE_', since macro names starting with an underscore and
+      followed by an uppercase letter are reserved in both C and C++.
+
+    - Function  `FT_Library_SetLcdFilterWeights'  now  also  activates
+      custom LCD filter weights (instead of just adjusting them).
+
+    - Support for  `unpatented hinting'  has been  completely removed:
+      Consequently,  the two  functions `FT_Face_CheckTrueTypePatents'
+      and  `FT_Face_SetUnpatentedHinting'  now  return  always  false,
+      doing nothing.
+
+    - The `ftgamma' demo  program has been modernized;  the gamma grid
+      display has been moved from `ftview' to this program.
+
+    - In `ftview',  it is now possible to cycle through  the available
+      LCD filtering modes.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.6.1 and 2.6.2
+
+  I. IMPORTANT CHANGES
+
+    - The auto-hinter now supports stem darkening, to be controlled by
+      the    new   `no-stem-darkening'    and   `darkening-parameters'
+      properties.   This is  an  experimental  feature contributed  by
+      Nikolaus Waxweiler, and  the interface might change  in a future
+      release.
+
+    - By default, stem darkening is now switched off (for both the CFF
+      engine and the  auto-hinter).  The main reason is  that you need
+      linear  alpha  blending  and  gamma correction  to  get  correct
+      rendering results, and  the latter is not yet  available in most
+      freely  available  rendering  stacks like  X11.   Applying  stem
+      darkening without proper gamma correction  leads to far too dark
+      rendering results.
+
+    - The   meaning  of   `FT_RENDER_MODE_LIGHT'  has   been  slightly
+      modified.   It  now  essentially  means `no  hinting  along  the
+      horizontal  axis'; in  particular,  no change  of glyph  advance
+      widths.  Consequently, the auto-hinter  is used for all scalable
+      font  formats  except  for  CFF.    It  is  planned  that  other
+      font-specific rendering engines (TrueType, Type 1) will follow.
+
+
+  II. MISCELLANEOUS
+
+    - The default  LCD filter  has been changed  to be  normalized and
+      color-balanced.
+
+    - For    better    compatibility   with    FontConfig,    function
+      `FT_Library_SetLcdFilter'  accepts   a  new   enumeration  value
+      `FT_LCD_FILTER_LEGACY1'   (which  has   the   same  meaning   as
+      `FT_LCD_FILTER_LEGACY').
+
+    - A large number of bugs have been detected by using the libFuzzer
+      framework,  which should  further  improve  handling of  invalid
+      fonts.  Thanks again to Kostya Serebryany and Bungeman!
+
+    - `TT_CONFIG_OPTION_MAX_RUNNABLE_OPCODES',  a   new  configuration
+      option, controls the maximum number of executed opcodes within a
+      bytecode program.  You don't want to change this except for very
+      special  situations (e.g.,  making a  library fuzzer  spend less
+      time to handle broken fonts).
+
+    - The smooth renderer has been made faster.
+
+    - The `ftstring' demo program now supports subpixel rendering; use
+      key `l' to cycle through the LCD modes.
+
+    - The `ftstring'  demo program now supports  colour rendering; use
+      the `space' key to cycle through various colour combinations.
+
+    - The graphical demo programs now use a default gamma value of 1.8
+      (instead of 1.2).
+
+
+======================================================================
+
+CHANGES BETWEEN 2.6 and 2.6.1
+
+  I. IMPORTANT BUG FIXES
+
+    - It turned  out that for CFFs  only the advance widths  should be
+      taken from the  `htmx' table, not the side  bearings.  This bug,
+      introduced in  version 2.6.0, makes  it necessary to  upgrade if
+      you are using  CFFs; otherwise, you get cropped  glyphs with GUI
+      interfaces like GTK or Qt.
+
+    - Accessing Type 42 fonts returned  incorrect results if the glyph
+      order of the embedded TrueType font differs from the glyph order
+      of the Type 42 charstrings table.
+
+
+  II. IMPORTANT CHANGES
+
+    - The header  file layout  has been  changed (again),  moving  all
+      header files except `ft2build.h' into a subdirectory tree.
+
+      Doing so  reduces the  possibility of  header file  name clashes
+      (e.g., FTGL's  `FTGlyph.h' with FreeType's `ftglyph.h')  on case
+      insensitive file systems like Mac OS X or Windows.
+
+      Applications  that  use  (a)  the  `freetype-config'  script  or
+      FreeType's `freetype2.pc' file for pkg-config to get the include
+      directory  for the  compiler,  and (b)  the  documented way  for
+      header inclusion like
+
+        #include <ft2build.h>
+        #include FT_FREETYPE_H
+        ...
+
+      don't need any change to the source code.
+
+    - Simple access  to named instances  in GX variation fonts  is now
+      available (in addition to the  previous method via FreeType's MM
+      interface).   In  the `FT_Face'  structure,  bits  16-30 of  the
+      `face_index' field hold the current named instance index for the
+      given face  index, and bits  16-30 of `style_flags'  contain the
+      number of  instances for  the given face  index.  `FT_Open_Face'
+      and friends also understand the  extended bits of the face index
+      parameter.
+
+      You need to enable  TT_CONFIG_OPTION_GX_VAR_SUPPORT for this new
+      feature.  Otherwise, bits  16-30 of the two fields  are zero (or
+      are ignored).
+
+    - Lao script support has been added to the auto-hinter.
+
+
+  III. MISCELLANEOUS
+
+    - The auto-hinter's Arabic script support has been enhanced.
+
+    - Superscript-like and  subscript-like glyphs  as used  by various
+      phonetic alphabets like the IPA  are now better supported by the
+      auto-hinter.
+
+    - The TrueType bytecode interpreter now runs slightly faster.
+
+    - Improved support for builds with cmake.
+
+    - The  function  `FT_CeilFix'  now   always  rounds  towards  plus
+      infinity.
+
+    - The  function  `FT_FloorFix'  now always  rounds  towards  minus
+      infinity.
+
+    - A  new load  flag `FT_LOAD_COMPUTE_METRICS'  has been  added; it
+      makes FreeType  ignore pre-computed  metrics, as needed  by font
+      validating  or  font  editing  programs.  Right  now,  only  the
+      TrueType  module supports  it  to ignore  data  from the  `hdmx'
+      table.
+
+    - Another round of bug fixes  to better handle broken fonts, found
+      by Kostya Serebryany <kcc@google.com>.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.5.5 and 2.6
+
+  I. IMPORTANT CHANGES
+
+    - Behdad  Esfahbod contributed  code  for improved  thread-safety,
+      which results in the following model.
+
+      * An `FT_Face' object can only be safely used from one thread at
+        a time.
+
+      * An `FT_Library'  object can  now be used  without modification
+        from multiple threads at the same time.
+
+      * `FT_Face' creation and destruction  with the same `FT_Library'
+        object can only be done from one thread at a time.
+
+      One can use a single  `FT_Library' object across threads as long
+      as a mutex lock is used around `FT_New_Face' and `FT_Done_Face'.
+      Any calls to `FT_Load_Glyph' and similar API are safe and do not
+      need the lock  to be held as  long as the same  `FT_Face' is not
+      used from multiple threads at the same time.
+
+    - Thai script support has been added to the auto-hinter.
+
+    - Arabic script support has been added to the auto-hinter.
+
+    - Following OpenType version 1.7,  advance widths and side bearing
+      values in  CFFs (wrapped  in an SFNT  structure) are  now always
+      taken from the `hmtx' table.
+
+    - Following OpenType  version 1.7, the  PostScript font name  of a
+      CFF font (wrapped in an SFNT structure) is now always taken from
+      the `name'  table.  This is  also true for  OpenType Collections
+      (i.e., TTCs using  CFFs subfonts instead of TTFs),  where it may
+      have a significant difference.
+
+    - Fonts natively hinted for  ClearType are now supported, properly
+      handling selector index 3 of the INSTCTRL bytecode instruction.
+
+    - Major improvements to the GX TrueType variation font handling.
+
+
+  II. MISCELLANEOUS
+
+    - A new auto-hinter  property `warping' can switch on  and off the
+      warping code  if this  experimental feature  is compiled  in (by
+      defining  the AF_CONFIG_OPTION_USE_WARPER  configuration option;
+      by default  this option is  now enabled but warping  is switched
+      off).
+
+      The AF_CONFIG_OPTION_USE_WARPER option itself is an old feature,
+      available   since  2006.    Warping   only   works  in   `light'
+      auto-hinting mode.   The idea of  the code is to  slightly scale
+      and  shift a  glyph  along the  non-hinted  dimension (which  is
+      usually the horizontal axis) so that as much of its segments are
+      aligned  (more or  less) to  the grid.   To find  out a  glyph's
+      optimal   scaling   and   shifting  value,   various   parameter
+      combinations are tried and scored.
+
+      See  file  `ftautoh.h' for  more;  the  demo programs  `ftdiff',
+      `ftview', and `ftgrid' can toggle warping with key `w'.
+
+    - Some  fields  in  the  `FTC_ImageTypeRec'  structure  have  been
+      changed from signed to unsigned  type, which better reflects the
+      actual usage.  It is also an additional means to protect against
+      malformed input.
+
+      This  change doesn't  break  the ABI;  however,  it might  cause
+      compiler warnings.
+
+    - Function `FT_Bitmap_New'  has been renamed  to `FT_Bitmap_Init',
+      since  this name  better reflects  its  function.   For backward
+      compatibility, the old function name is still available.
+
+    - Function   `FT_Get_X11_Font_Format'   has    been   renamed   to
+      `FT_Get_Font_Format',  since  this   name  better  reflects  its
+      function.  For backward compatibility,  the old function name is
+      still available.
+
+      Additionally, the header  file macro for this  function has been
+      renamed to  `FT_FONT_FORMATS_H' (the old name  `FT_XFREE86_H' is
+      retained for backward compatibility).
+
+    - Various improvements to the `ftgrid' demo program.
+
+      . It  can  now  display  GX and  MM  fonts  while  interactively
+        manipulating the axes (with keys F2, F3, and F4).
+
+      . Anti-aliasing rendering  modes can now be  selected (with keys
+        F5 and F6).
+
+      . The display of point numbers can be toggled with key `D'.
+
+    - Various improvements to the `ftdump' demo program.
+
+      . It now displays information on MM and GX variation axes.
+
+      . New  command line option  `-u' makes  it output data  in utf-8
+        encoding.
+
+    - The `ftmulti'  demo program can  now handle up  to six MM  or GX
+      axes.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.5.4 and 2.5.5
+
+  I. IMPORTANT BUG FIXES
+
+    - Handling of  uncompressed PCF files works again (bug  introduced
+      in version 2.5.4).
+
+
+======================================================================
+
+CHANGES BETWEEN 2.5.3 and 2.5.4
+
+  I. IMPORTANT BUG FIXES
+
+    - A   variant  of   vulnerability  CVE-2014-2240   was  identified
+      (cf.  https://savannah.nongnu.org/bugs/?43661) and  fixed in the
+      new CFF driver.  All users should upgrade.
+
+    - The new auto-hinter code using HarfBuzz crashed for some invalid
+      fonts.
+
+    - Many fixes to better protect against malformed input.
+
+
+  II. IMPORTANT CHANGES
+
+    - Full auto-hinter support of the Devanagari script.
+
+    - Experimental auto-hinter support of the Telugu script.
+
+    - CFF stem darkening behaviour can now be controlled at build time
+      using the eight macros
+
+        CFF_CONFIG_OPTION_DARKENING_PARAMETER_{X,Y}{1,2,3,4}    .
+
+    - Some fields in the `FT_Bitmap'  structure have been changed from
+      signed to unsigned type, which better reflects the actual usage.
+      It  is also  an additional  means to  protect against  malformed
+      input.
+
+      This  change doesn't  break  the ABI;  however,  it might  cause
+      compiler warnings.
+
+
+  III. MISCELLANEOUS
+
+    - Improvements to  the auto-hinter's algorithm to  recognize stems
+      and local extrema.
+
+    - Function `FT_Get_SubGlyph_Info' always returned an error even in
+      case of success.
+
+    - Version  2.5.1 introduced  major bugs  in  the cjk  part of  the
+      auto-hinter, which are now fixed.
+
+    - The  `FT_Sfnt_Tag'  enumeration  values  have  been  changed  to
+      uppercase,  e.g.  `FT_SFNT_HEAD'.   The lowercase  variants  are
+      deprecated.    This  is   for  orthogonality   with  all   other
+      enumeration (and enumeration-like) values in FreeType.
+
+    - `cmake' now supports builds of FreeType as an OS X framework and
+      for iOS.
+
+    - Improved project files for vc2010, introducing a property file.
+
+    - The  documentation generator  for  the API  reference  has  been
+      updated to produce  better HTML code (with proper  CSS).  At the
+      same time, the documentation got a better structure.
+
+    - The FT_LOAD_BITMAP_CROP flag is obsolete;  it is not used by any
+      driver.
+
+    - The  TrueType  DELTAP[123]  bytecode instructions  now  work  in
+      subpixel hinting  mode as described in  the ClearType whitepaper
+      (i.e., for touched points in the non-subpixel direction).
+
+    - Many small improvements to the internal arithmetic routines.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.5.2 and 2.5.3
+
+  I. IMPORTANT BUG FIXES
+
+    - A vulnerability (CVE-2014-2240) was  identified and fixed in the
+      new  CFF driver  (cf.  https://savannah.nongnu.org/bugs/?41697).
+      All users should upgrade.
+
+    - More  bug  fixes related  to  correct  positioning of  composite
+      glyphs.
+
+    - Many fixes to better protect against malformed input.
+
+
+  II. IMPORTANT CHANGES
+
+    - FreeType can now use the HarfBuzz library to greatly improve the
+      auto-hinting of  fonts that  use OpenType features:  Many glyphs
+      that are part  of such features but don't have  cmap entries are
+      now handled  properly, for  example small caps  or superscripts.
+      Define the configuration  macro FT_CONFIG_OPTION_USE_HARFBUZZ to
+      activate HarfBuzz support.
+
+      You need HarfBuzz version 0.9.19 or newer.
+
+      Note that HarfBuzz depends on  FreeType; this currently causes a
+      chicken-and-egg problem  that can be  solved as follows  in case
+      HarfBuzz is not yet installed on your system.
+
+        1. Compile  and  install  FreeType without  the  configuration
+           macro FT_CONFIG_OPTION_USE_HARFBUZZ.
+
+        2. Compile and install HarfBuzz.
+
+        3. Define  macro  FT_CONFIG_OPTION_USE_HARFBUZZ, then  compile
+           and install FreeType again.
+
+      With FreeType's  `configure' script the procedure  boils down to
+      configure, build, and install FreeType, then configure, compile,
+      and  install  HarfBuzz,  then configure,  compile,  and  install
+      FreeType again (after executing `make distclean').
+
+    - All  libraries FreeType  depends on  are now  checked using  the
+      `pkg-config' configuration files  first, followed by alternative
+      methods.
+
+    - The  new  value  `auto'  for the  various  `--with-XXX'  library
+      options   (for   example   `--with-harfbuzz=auto')   makes   the
+      `configure' script automatically link to the libraries it finds.
+      This is now the default.
+
+    - In case FreeType's `configure' script  can't find a library, you
+      can  pass environment  variables to  circumvent pkg-config,  and
+      those variables  have been  harmonized as  a consequence  of the
+      changes mentioned above:
+
+        LIBZ           -> removed; use LIBZ_CFLAGS and LIBZ_LIBS
+        LIBBZ2         -> removed; use BZIP2_CFLAGS and BZIP2_LIBS
+        LIBPNG_LDFLAGS -> LIBPNG_LIBS
+
+      `./configure --help' shows all available environment variables.
+
+    - The `freetype-config'  script now understands  option `--static'
+      to emit static linking information.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.5.1 and 2.5.2
+
+  I. IMPORTANT BUG FIXES
+
+    - Improving the display of some broken TrueType fonts introduced a
+      bug  that made  FreeType crash  on some  popular (but  not fully
+      conformant) fonts like `ahronbd.ttf'.
+
+    - Another round of improvements to correct positioning and hinting
+      of composite glyphs in TrueType fonts.
+
+
+  II. MISCELLANEOUS
+
+    - Version  2.5.1  introduced a  bug  in  handling embedded  bitmap
+      strikes of  TrueType fonts,  causing garbage display  under some
+      circumstances.
+
+    - The   `ftgrid'   demo   program    couldn't   be   compiled   in
+      non-development builds.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.5 and 2.5.1
+
+  I. IMPORTANT BUG FIXES
+
+    - For  some WinFNT  files,  the last  glyph  wasn't displayed  but
+      incorrectly marked as invalid.
+
+    - The vertical size of glyphs was  incorrectly set after a call to
+      `FT_GlyphSlot_Embolden', resulting in clipped glyphs.
+
+    - Many fields of the `PCLT' table in SFNT based fonts (if accessed
+      with `FT_Get_Sfnt_Table') were computed incorrectly.
+
+    - In TrueType fonts,  hinting of composite glyphs  could sometimes
+      deliver  incorrect positions  of  components or  even  distorted
+      shapes.
+
+
+  II. IMPORTANT CHANGES
+
+    - WOFF font format support has been added.
+
+    - The auto-hinter now supports Hebrew.  Greek and Cyrillic support
+      has been improved.
+
+    - Support for the forthcoming `OS/2'  SFNT table version 5, as can
+      be found e.g. in the `Sitka' font family for Windows 8.1.
+
+    - The header  file layout  has been changed.   After installation,
+      all files are now located in `<prefix>/include/freetype2'.
+
+      Applications  that  use   (a)  `freetype-config'  or  FreeType's
+      `pkg-config' file to get the include directory for the compiler,
+      and (b) the documented way for header inclusion like
+
+        #include <ft2build.h>
+        #include FT_FREETYPE_H
+        ...
+
+      don't need any change to the source code.
+
+
+  III. MISCELLANEOUS
+
+    - The stem  darkening feature  of the  new CFF  engine can  now be
+      fine-tuned with the new `darkening-parameters' property.
+
+    - `ftgrid' has been updated to toggle various engines with the `H'
+      key, similar to `ftview' and `ftdiff'.
+
+    - The functionality of `ttdebug' has been greatly enhanced.
+
+      . It now displays twilight, storage, and control value data; key
+        `T' shows the twilight point  table, key `S' the storage data,
+        and key `C' the control value table.
+
+      . Some  keys  have  been  reassigned  from  lowercase  to  their
+        uppercase equivalents; for example `q'  to quit the program is
+        now `Q'.
+
+      . Key `f' finishes the current function.
+
+      . Key `R' restarts the debugger.
+
+      . Keys `b' and `p' set a breakpoint.
+
+      . Key `B' provides a function call backtrace.
+
+    - Better support of ARMv7 and x86_64 processors.
+
+    - Apple's `sbix' color bitmap format is now supported.
+
+    - Improved   auto-hinter  rendering   for  many   TrueType  fonts,
+      especially in the range 20-40ppem.
+
+    - A  new face  flag  `FT_FACE_FLAG_COLOR' has  been  added (to  be
+      accessed with the macro `FT_HAS_COLOR').
+
+    - `FT_Gzip_Uncompress'   (modeled    after   zlib's   `uncompress'
+      function)  has been  added; this  is a  by-product of  the newly
+      added WOFF support.
+
+    - Support for  a build with  `cmake' has been contributed  by John
+      Cary <cary@txcorp.com>.
+
+    - Support for x64  builds with Visual C++ has  been contributed by
+      Kenneth Miller <kennethadammiller@yahoo.com>
+
+    - Manual pages for most demo programs have been added.
+
+    - The GETINFO bytecode instruction for TrueType fonts was buggy if
+      used to retrieve subpixel hinting information.  It was necessary
+      to set  selector bit 6  to get  results for selector  bits 7-10,
+      which is wrong.
+
+    - Improved computation  of emulated vertical metrics  for TrueType
+      fonts.
+
+    - Fixed horizontal start-up position of vertical phantom points in
+      TrueType bytecode.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.4.12 and 2.5
+
+  I. IMPORTANT BUG FIXES
+
+    - The cache manager function `FTC_Manager_Reset'  didn't flush the
+      cache.
+
+
+  II. IMPORTANT CHANGES
+
+    - Behdad Esfahbod  (on behalf  of Google) contributed  support for
+      color embedded bitmaps (eg. color emoji).
+
+      A  new  load  flag,  FT_LOAD_COLOR, makes  FreeType  load  color
+      embedded-bitmaps, following this draft specification
+
+        https://color-emoji.googlecode.com/git/specification/v1.html
+
+      which defines two new SFNT  tables, `CBDT' and `CBLC' (named and
+      modeled  after  `EBDT'  and `EBLC',  respectively).   The  color
+      bitmaps  are  stored in  the  new  FT_PIXEL_MODE_BGRA format  to
+      represent BGRA  pre-multiplied sRGB  images.  If PNG  support is
+      available,  PNG color  images as  defined in  the same  proposed
+      specification are supported also.
+
+      Note that  color bitmaps  are converted  to grayscale  if client
+      didn't ask for color.
+
+    - As  announced in  the  previous release,  the  old FreeType  CFF
+      engine  is now  disabled by  default.  It  can be  conditionally
+      compiled     by     defining     the     configuration     macro
+      CFF_CONFIG_OPTION_OLD_ENGINE.
+
+    - As announced in the previous release,  all code related to macro
+      FT_CONFIG_OPTION_OLD_INTERNALS  has been removed,  thus becoming
+      obsolete.
+
+
+  III. MISCELLANEOUS
+
+    - The  property API  (`FT_Property_Get' and  `FT_Property_Set') is
+      now declared as stable.
+
+      The  exception,   however,  are  the   experimental  auto-hinter
+      properties `glyph-to-script-map' and `fallback-script' which are
+      subject to change in a forthcoming release.
+
+    - `ftview' has been updated to  support color embedded bitmaps; it
+      can be toggled on and off  with key `c'.  The small cache toggle
+      is now key `K'.
+
+    - It  is now  possible  to  control the  version  of the  TrueType
+      hinting engine  using the new `interpreter-version'  property of
+      the  `truetype' module:  Versions 35  and 38  (the default)  are
+      supported,  which  roughly  corresponds to  disable  and  enable
+      subpixel hinting support, respectively.
+
+      In  both  `ftview'  and  `ftdiff',  switching  between  the  two
+      versions  can be  done  with  key `H'.   In  the `ftbench'  demo
+      program, command line option `-H'  has been extended to activate
+      the non-default interpreter version.
+
+    - The `ttdebug' program has been further improved.  In particular,
+      it accepts a new command line  option `-H' to select the hinting
+      engine.
+
+    - `ftdump's verbose option has been renamed to `-V'.  For all demo
+      programs, `-v' now shows version information.
+
+    - Another round of TrueType subpixel hinting fixes.
+
+    - The `apinames' tool can now create an import file for NetWare.
+
+    - 64bit compilation of the new CFF engine was buggy.
+
+    - Some fixes to improve robustness in memory-tight situations.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.4.11 and 2.4.12
+
+    - We have another CFF parsing and hinting engine!  Written by Dave
+      Arnold <darnold@adobe.com>,  this work  has been  contributed by
+      Adobe in  collaboration with Google.   It is vastly  superior to
+      the old CFF engine, and it  will replace it in the next release.
+      Right  now,  it  is  still  off by  default,  and  you  have  to
+      explicitly select it using  the new `hinting-engine' property of
+      the cff driver:
+
+        ...
+        #include FT_MODULE_H
+        #include FT_CFF_DRIVER_H
+
+        FT_Library  library;
+        int         engine = FT_CFF_HINTING_ADOBE;
+
+
+        ...
+        FT_Property_Set( library, "cff", "hinting-engine", &engine );
+
+      The code has  a (mature) beta status; we encourage  all users to
+      test it and report any problems.
+
+      In case you want to activate the new CFF engine unconditionally,
+      apply this patch:

+
+     return FT_Err_Ok;
+--- snip ---
+
+    - The  macro FT_CONFIG_OPTION_OLD_INTERNALS  is no  longer set  by
+      default.  In  the next  release, we  will completely  remove the
+      associated code.   Please update your  programs in case  you are
+      still using this macro.
+
+
+  II. MISCELLANEOUS
+
+    - The  (top-level)  `configure'  script   now  respects  the  MAKE
+      environment variable  to specify a `make' binary.   For backward
+      compatibility, GNUMAKE still overrides MAKE, though.
+
+    - The `ftview'  and `ftdiff'  demo programs have  been redesigned,
+      showing  more options  permanently  on the  screen, among  other
+      minor improvements.
+
+    - Using the `H'  key, it is now possible to  select the CFF engine
+      in both `ftview' and `ftdiff'.
+
+    - The new command line option `-H' for `ftbench' selects the Adobe
+      CFF engine.
+
+    - It is  now possible  to directly select  the LCD  rendering mode
+      with the keys `A'-`F' in  `ftview'.  The key mapping for cycling
+      through LCD modes  has been changed from `K' and  `L' to `k' and
+      `l', and  toggling custom LCD  filtering is no longer  mapped to
+      key `F' but to key `L'.
+
+    - In `ftdiff',  key `x' toggles  between layout modes:  Either use
+      the  advance width  (this is  new and  now the  default) or  the
+      bounding box information to determine line breaks.
+
+    - For all demo  tools, the new command line option  `-v' shows the
+      version.
+
+    - For the demo tools with a GUI, the new command line options `-w'
+      and `-h' select  the width and the height of  the output window,
+      respectively.
+
+    - The `ttdebug' program was broken and has been reactivated.  Note
+      that this program is not compiled by default.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.4.10 and 2.4.11
+
+  I. IMPORTANT BUG FIXES
+
+    - Some vulnerabilities in the  BDF implementation have been fixed.
+      Users of this font format should upgrade.
+
+
+  II. IMPORTANT CHANGES
+
+    - Subpixel  hinting support  has been  contributed by  Infinality,
+      based on Greg Hitchcock's whitepaper at
+
+        https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx
+
+      Originally, it was a separate patch available from
+
+        http://www.infinality.net/blog/
+
+      and which has been integrated.
+
+      Note that  ClearType support is not  completely implemented!  In
+      particular,  full support  for the  options `compatible_widths',
+      `symmetrical_smoothing,  and  `bgr'  (via the  GETINFO  bytecode
+      instruction) is missing.
+
+      Activation of  subpixel hinting  support can be  controlled with
+      the `TT_CONFIG_OPTION_SUBPIXEL_HINTING' configuration option; it
+      is switched off by default.  This feature is still experimental;
+      we welcome test reports!
+
+    - Support for OpenType collections (OTC) has been added.
+
+    - Pure CFF fonts within an SFNT wrapper are now supported.
+
+
+  III. MISCELLANEOUS
+
+    - Minor rendering improvements to the auto-hinter.
+
+    - `FT_GlyphSlot_Oblique' now uses a shear angle of 12°.
+
+    - Experimental support  to handle `property modules',  for example
+      to control the  behaviour of the auto-hinter.   The API consists
+      of two new functions, `FT_Property_Set' and `FT_Property_Get'.
+
+      The code is  still subject to change and should  not be used for
+      production.
+
+    - The `ftdiff' demo program now supports UTF-8 encoded input files
+      for option `-f'.
+
+    - Using keys `r' and `R', you can now adjust the stroker radius in
+      the `ftview' demo program.
+
+    - Other, minor fixes and improvements.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.4.9 and 2.4.10
+
+  I. IMPORTANT BUG FIXES
+
+    - Incremental glyph loading as needed by ghostscript was broken.
+
+
+  II. MISCELLANEOUS
+
+    - A new  function `FT_Outline_EmboldenXY',  contributed by  Alexei
+      Podtelezhnikov.
+
+    - In the `ftview' demo program, key `e' has been replaced with `x'
+      and `y' to  embolden in  the horizontal and  vertical direction,
+      respectively.
+
+    - The glyph  spacing computation  in `FT_GlyphSlot_Embolden'  (and
+      similar code in `ftview') has been improved.
+
+    - Minor  improvements to  the TrueType  bytecode  interpreter  and
+      glyph loader, the auto-hinter, and the B/W rasterizer.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.4.8 and 2.4.9
+
+  I. IMPORTANT BUG FIXES
+
+    - Another round of fixes to better handle invalid fonts.   Many of
+      them are vulnerabilities  (see CVE-2012-1126 up to CVE-2012-1144
+      and SA48320) so all users should upgrade.
+
+
+  II. MISCELLANEOUS
+
+    - The `ENCODING -1 <n>' format of BDF fonts is now supported.
+
+    - For BDF fonts,  support for the whole Unicode encoding range has
+      been added.
+
+    - Better TTF support for x_ppem != y_ppem.
+
+    - `FT_Get_Advances' sometimes returned bogus values.
+
+    - The  demo  programs  no  longer  recognize  and  handle  default
+      suffixes; you now have to always specify the complete font name.
+
+    - Better rendering and LCD mode cycling added to `ftview'.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.4.7 and 2.4.8
+
+  I. IMPORTANT BUG FIXES
+
+    - Some vulnerabilities in handling CID-keyed PostScript fonts have
+      been fixed; see CVE-2011-3439.
+
+
+  II. MISCELLANEOUS
+
+    - Chris Liddell contributed a new API, `FT_Get_PS_Font_Value',  to
+      retrieve most of the dictionary keys in Type 1 fonts.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.4.6 and 2.4.7
+
+  I. IMPORTANT BUG FIXES
+
+    - Some  vulnerabilities in handling Type 1 fonts  have been fixed;
+      see CVE-2011-3256.
+
+
+  II. MISCELLANEOUS
+
+    - FreeType  now properly  handles ZapfDingbats  glyph names  while
+      constructing a Unicode character map (for fonts which don't have
+      one).
+
+
+======================================================================
+
+CHANGES BETWEEN 2.4.5 and 2.4.6
+
+  I. IMPORTANT BUG FIXES
+
+    - For TrueType based fonts, the ascender and descender values were
+      incorrect sometimes  (off by a pixel if the ppem value was not a
+      multiple of 5).   Depending on the use you might now  experience
+      a different  layout; the  change should  result in  better, more
+      consistent line spacing.
+
+    - Fix CVE-2011-0226  which causes a  vulnerability while  handling
+      Type 1 fonts.
+
+    - BDF fonts  containing  glyphs with negative values  for ENCODING
+      were  incorrectly  rejected.  This  bug has  been introduced  in
+      FreeType version 2.2.0.
+
+    - David Bevan contributed a major revision of the FreeType stroker
+      code:
+
+      . The behaviour of FT_STROKER_LINEJOIN_BEVEL has been corrected.
+
+      . A new  line join style,  FT_STROKER_LINEJOIN_MITER_FIXED,  has
+        been introduced to support PostScript and PDF miter joins.
+
+      . FT_STROKER_LINEJOIN_MITER_VARIABLE  has been introduced  as an
+        alias for FT_STROKER_LINEJOIN_MITER.
+
+      . Various stroking glitches has been fixed.
+
+
+  II. MISCELLANEOUS
+
+      - SFNT bitmap fonts which contain an outline glyph for `.notdef'
+        only no longer set the FT_FACE_FLAG_SCALABLE flag.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.4.4 and 2.4.5
+
+  I. IMPORTANT BUG FIXES
+
+    - A rendering regression  for second-order Bézier curves  has been
+      fixed, introduced in 2.4.3.
+
+
+  II. IMPORTANT CHANGES
+
+    - If autohinting  is not  explicitly disabled,  FreeType now  uses
+      the autohinter if  a TrueType based font doesn't  contain native
+      hints.
+
+    - The load flag FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH  has been made
+      redundant and  is simply ignored;  this means that FreeType  now
+      ignores the global advance width value in TrueType fonts.
+
+
+  III. MISCELLANEOUS
+
+    - `FT_Sfnt_Table_Info' can now return the number of SFNT tables of
+      a font.
+
+    - Support for PCF files compressed with bzip2 has been contributed
+      by Joel  Klinghed.  To  make this  work, the  OS must  provide a
+      bzip2 library.
+
+    - Bradley  Grainger  contributed  project  and  solution  files in
+      Visual Studio 2010 format.
+
+    - Again some fixes to better handle broken fonts.
+
+    - Some improvements to the B/W rasterizer.
+
+    - Fixes to the cache module to improve robustness.
+
+    - Just  Fill Bugs contributed (experimental) code to compute  blue
+      zones for CJK Ideographs, improving the alignment of  horizontal
+      stems at the top or bottom edges.
+
+    - The `ftgrid' demo program  can now display  autohinter segments,
+      to be toggled on and off with key `s'.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.4.3 and 2.4.4
+
+  I. IMPORTANT BUG FIXES
+
+    - UVS support (TrueType/OpenType cmap format 14) support is fixed.
+      This regression has been introduced in version 2.4.0.
+
+
+  II. MISCELLANEOUS
+
+    - Detect tricky fonts (e.g. MingLiU)  by the lengths and checksums
+      of Type42-persistent subtables (`cvt ', `fpgm', and `prep') when
+      a TrueType font without family name is given.  The previous fix,
+      introduced in 2.4.3,  was too rigorous,  causing many  subsetted
+      fonts (mainly  from PDF files) displayed badly  because FreeType
+      forced  rendering with  the TrueType bytecode engine  instead of
+      the autohinter.
+
+    - Better support for 64bit platforms.
+
+    - More fixes to improve handling of broken fonts.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.4.2 and 2.4.3
+
+  I. IMPORTANT BUG FIXES
+
+    - Fix rendering of certain cubic, S-shaped arcs.   This regression
+      has been introduced in version 2.4.0.
+
+
+  II. MISCELLANEOUS
+
+    - To  fix  the  above  mentioned  rendering  issue,  a  new spline
+      flattening algorithm  has been  introduced which  speeds up both
+      conic and cubic arcs.
+
+    - Handling of broken fonts has been further improved.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.4.1 and 2.4.2
+
+  I. IMPORTANT BUG FIXES
+
+    - A stack overflow in CFF Type2 CharStrings interpreter is fixed.
+
+    - Handling Type 42 font deallocation was broken; additionally, the
+      library is now more robust against malformed Type 42 fonts.
+
+
+  II. MISCELLANEOUS
+
+    - Two new functions,  `FT_Reference_Library' (in FT_MODULE_H)  and
+      `FT_Reference_Face'  (in  FT_FREETYPE_H),  have  been  added  to
+      simplify life-cycle management.  A counter gets initialized to 1
+      at the  time an  FT_Library (or  FT_Face) structure  is created.
+      The  two  new   functions  increment  the  respective   counter.
+      `FT_Done_Library' and `FT_Done_Face' then only destroy a library
+      or face if the counter is 1, otherwise they simply decrement the
+      counter.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.4.0 and 2.4.1
+
+  I. IMPORTANT CHANGES
+
+    - A serious bug in the  CFF font module prevented  display of many
+      glyphs in CFF fonts like `MinionPro-Regular.otf'.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.3.12 and 2.4.0
+
+  I. IMPORTANT CHANGES
+
+    - Since May  2010, all  patents  regarding  the TrueType  bytecode
+      interpreter have expired worldwide.  Consequently, we now define
+      TT_CONFIG_OPTION_BYTECODE_INTERPRETER by  default (and  undefine
+      TT_CONFIG_OPTION_UNPATENTED_HINTING).
+
+    - A new function `FT_Library_SetLcdFilterWeights' is available  to
+      adjust the filter weights set by `FT_Library_SetLcdFilter'.
+
+
+  II. MISCELLANEOUS
+
+    - Thanks to many reports from Robert Święcki, FreeType's stability
+      in handling broken or damaged fonts is much improved.
+
+    - Support  for LCD  filter  control has  been  added to  the  demo
+      programs `ftdiff' and `ftview'.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.3.11 and 2.3.12
+
+  I. IMPORTANT CHANGES
+
+    - For  `FT_Open_Face',  new  parameters  are  available  to ignore
+      preferred family names: FT_PARAM_TAG_IGNORE_PREFERRED_FAMILY and
+      FT_PARAM_TAG_IGNORE_PREFERRED_SUBFAMILY.
+
+
+  II. MISCELLANEOUS
+
+    - Support  for  incremental  font  loading  (controlled  with  the
+      FT_CONFIG_OPTION_INCREMENTAL macro) is now active by default.
+
+    - Better support for vertical metrics.
+
+    - Various minor bug fixes.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.3.10 and 2.3.11
+
+  I. IMPORTANT BUG FIXES
+
+    - Version 2.3.10 broke PCF support.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.3.10 and 2.3.9
+
+  I. IMPORTANT BUG FIXES
+
+    - If all  ASCII digits in a  font have the  same (unscaled) width,
+      the autohinter respects this and won't change it.
+
+    - TrueType fonts  are now  rasterized correctly  if the horizontal
+      and vertical resolution differ.
+
+    - Type 1 fonts are now handled with increased precision internally
+      to avoid serious rounding issues if non-integral coordinates are
+      encountered.
+
+    - Horizontally  condensed CFF  fonts (using the font  matrix) were
+      rendered  incorrectly.   This  bug  has  been  introduced  after
+      release 2.3.5.
+
+
+  II. IMPORTANT CHANGES
+
+    - Support for the SFNT cmap 13 table format (as defined by the new
+      OpenType 1.6 specification) has been added.
+
+    - B/W rasterization  of well-hinted TrueType  fonts at small sizes
+      has been greatly improved.
+
+    - Calculation  of  vertical  metrics in  OpenType  fonts has  been
+      improved.
+
+
+  III. MISCELLANEOUS
+
+    - It  is now  possible to  change  the emboldening  factor in  the
+      `ftview' demo program with keys `e' and `E'.
+
+    - It is  now possible  to change the  slant value in  the `ftview'
+      demo program with keys `s' and `S'.
+
+    - The  5-levels  grayscale  mode of  the `ftraster'  module (which
+      FreeType doesn't use by default) was broken since version 2.3.0.
+
+    - Compilation of the  `ftgrays' and `ftraster' modules  was broken
+      in stand-alone mode.
+
+    - Various fixes for compilation on 64bit and 16bit architectures.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.3.9 and 2.3.8
+
+  I. IMPORTANT BUG FIXES
+
+    - Very unfortunately, FreeType 2.3.8 contained a change that broke
+      its  official ABI.  The  end result  is  that programs  compiled
+      against previous versions of the library, but dynamically linked
+      to  2.3.8 can  experience  memory corruption  if  they call  the
+      `FT_Get_PS_Font_Info' function.
+
+      We recommend all users to  upgrade to 2.3.9 as soon as possible,
+      or to downgrade to a previous  release of the library if this is
+      not an option.
+
+      The  origin of the  bug is  that a  new field  was added  to the
+      publicly  defined  `PS_FontInfoRec'  structure.   Unfortunately,
+      objects of this  type can be stack or  heap allocated by callers
+      of   `FT_Get_PS_Font_Info',  resulting   in   a  memory   buffer
+      overwrite with its implementation in 2.3.8.
+
+      If  you want to  know whether  your code  is vulnerable  to this
+      issue,  simply  search  for  the  substrings  `PS_FontInfo'  and
+      `PS_Font_Info' in your source code.  If none is found, your code
+      is safe and is not affected.
+
+      The FreeType team apologizes for the problem.
+
+    - The POSIX support  of MacOS resource-fork fonts  (Suitcase fonts
+      and LaserWriter Type1 PostScript fonts) was broken in 2.3.8.  If
+      FreeType2 is built without Carbon framework, these fonts are not
+      handled correctly.  Version 2.3.7 didn't have this bug.
+
+    - `FT_Get_Advance' (and `FT_Get_Advances') returned bad values for
+      almost all font formats except TrueType fonts.
+
+    - Fix a bug  in the SFNT  kerning table  loader/parser which could
+      crash the engine if certain malformed tables were encountered.
+
+    - Composite SFNT bitmaps are now handled correctly.
+
+
+  II. IMPORTANT CHANGES
+
+    - The   new  functions   `FT_Get_CID_Is_Internally_CID_keyed'  and
+      `FT_Get_CID_From_Glyph_Index'  can be  used to  access CID-keyed
+      CFF fonts  via CID  values.  This code  has been  contributed by
+      Michael Toftdal.
+
+
+  III. MISCELLANEOUS
+
+    - `FT_Outline_Get_InsideBorder'  returns   FT_STROKER_BORDER_RIGHT
+      for empty outlines.  This was incorrectly documented.
+
+    - The `ftview' demo program now supports UTF-8 encoded strings.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.3.8 and 2.3.7
+
+  I. IMPORTANT BUG FIXES
+
+    - CID-keyed fonts in an SFNT wrapper were not handled correctly.
+
+    - The smooth renderer produced truncated images (on the right) for
+      outline parts with negative horizontal values.  Most fonts don't
+      contain outlines left  to the y coordinate axis, but  the effect
+      was very noticeable for outlines processed with FT_Glyph_Stroke,
+      using thick strokes.
+
+    - `FT_Get_TrueType_Engine_Type'  returned a  wrong  value if  both
+      configuration  macros  TT_CONFIG_OPTION_BYTECODE_INTERPRETER and
+      TT_CONFIG_OPTION_UNPATENTED_HINTING were defined.
+
+    - The  `face_index'  field  in   the  `FT_Face'  structure  wasn't
+      initialized properly after calling FT_Open_Face and friends with
+      a positive face index for CFFs,  WinFNTs, and, most importantly,
+      for TrueType Collections (TTCs).
+
+
+  II. IMPORTANT CHANGES
+
+    - Rudimentary support for Type 1  fonts and CID-keyed Type 1 fonts
+      in an SFNT wrapper has been  added -- such fonts are used on the
+      Mac.  The core  SFNT tables `TYP1' and `CID '  are passed to the
+      PS Type 1  and CID-keyed PS font drivers;  other tables (`ALMX',
+      `BBOX', etc.) are not supported yet.
+
+    - A  new interface  to extract  advance values  of glyphs  without
+      loading their outlines has been added.  The functions are called
+      `FT_Get_Advance' and `FT_Get_Advances'; they are defined in file
+      `ftadvanc.h' (to be accessed as FT_ADVANCES_H).
+
+    - A new function `FT_Get_FSType_Flags' (in FT_FREETYPE_H) has been
+      contributed  by   David  Bevan  to  access   the  embedding  and
+      subsetting restriction information of fonts.
+
+
+  III. MISCELLANEOUS
+
+    - FT_MulFix is now an inlined function; by default, assembler code
+      is provided for x86 and ARM.  See FT_CONFIG_OPTION_INLINE_MULFIX
+      and FT_CONFIG_OPTION_NO_ASSEMBLER (in ftoption.h) for more.
+
+    - The handling of `tricky' fonts  (this is, fonts which don't work
+      with the  autohinter, needing the font  format's hinting engine)
+      has been generalized and changed slightly:
+
+      . A new  face flag  FT_FACE_FLAG_TRICKY indicates that  the font
+        format's  hinting engine is  necessary for  correct rendering.
+        The macro FT_IS_TRICKY can be used to check this flag.
+
+      . FT_LOAD_NO_HINTING is now ignored for tricky fonts.  To really
+        force  raw  loading  of  such fonts  (without  hinting),  both
+        FT_LOAD_NO_HINTING  and FT_LOAD_NO_AUTOHINT  must  be used  --
+        this is something which you probably never want to do.
+
+      . Tricky  TrueType fonts  always use  the  bytecode interpreter,
+        either the patented or unpatented version.
+
+    - The  function  `FT_GlyphSlot_Own_Bitmap'  has  been  moved  from
+      FT_SYNTHESIS_H to FT_BITMAP_H; it  is now part of the `official'
+      API.   (The functions  in  FT_SYNTHESIS_H are  still subject  to
+      change, however.)
+
+    - In the  `ftdiff'  demo  program you  can now  toggle the  use of
+      FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH with key `a'.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.3.7 and 2.3.6
+
+  I. IMPORTANT BUG FIXES
+
+    - If the library  was compiled on an i386  platform using gcc, and
+      compiler  option -O3 was  given, `FT_MulFix'  sometimes returned
+      incorrect  results   which  could  have   caused  problems  with
+      `FT_Request_Metrics'   and  `FT_Select_Metrics',   returning  an
+      incorrect descender size.
+
+    - Pure CFFs without  subfonts were scaled incorrectly  if the font
+      matrix  was  non-standard.  This  bug  has  been  introduced  in
+      version 2.3.6.
+
+    - The  `style_name'  field  in  the  `FT_FaceRec'  structure often
+      contained  a wrong  value for  Type 1  fonts.  This misbehaviour
+      has been  introduced  in  version  2.3.6  while  trying  to  fix
+      another   problem.   [Note,  however,   that   this   value   is
+      informative only  since  the  used  algorithm to  extract  it is
+      very simplistic.]
+
+
+  II. IMPORTANT CHANGES
+
+    - Two      new      macros,      FT_OUTLINE_SMART_DROPOUTS     and
+      FT_OUTLINE_EXCLUDE_STUBS,  have been introduced.   Together with
+      FT_OUTLINE_IGNORE_DROPOUTS (which  was ignored previously) it is
+      now possible to control the dropout mode  of the `raster' module
+      (for B&W rasterization),   using  the   `flags'  field   in  the
+      `FT_Outline' structure.
+
+    - The TrueType bytecode interpreter now passes the dropout mode to
+      the B&W rasterizer.  This greatly increases the output for small
+      ppem values of many fonts like `pala.ttf'.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.3.6 and 2.3.5
+
+  I. IMPORTANT BUG FIXES
+
+    - A  bunch of  potential security  problems have  been found.  All
+      users should update.
+
+    - Microsoft  Unicode  cmaps  in  TrueType  fonts  are  now  always
+      preferred over Apple cmaps.  This is not a bug per se, but there
+      exist some buggy  fonts created for MS which  have broken  Apple
+      cmaps.  This affects  only the automatic  selection of FreeType;
+      it's always possible to manually select an Apple Unicode cmap if
+      desired.
+
+    - Many bug fixes to the TrueType bytecode interpreter.
+
+    - Improved Mac support.
+
+    - Subsetted CID-keyed CFFs are now supported correctly.
+
+    - CID-keyed CFFs with subfonts which are scaled in a  non-standard
+      way are now handled correctly.
+
+    - A call to FT_Open_Face with `face_index' < 0 crashed FreeType if
+      the font was a Windows (bitmap) FNT/FON.
+
+
+  II. IMPORTANT CHANGES
+
+    - The new function `FT_Get_CID_Registry_Ordering_Supplement' gives
+      access to  those fields in a CID-keyed font.  The code  has been
+      contributed by Derek Clegg.
+
+    - George Williams  contributed  code  to validate  the new  `MATH'
+      OpenType  table (within  the `otvalid'  module).  The  `ftvalid'
+      demo program has been extended accordingly.
+
+    - An API for cmap 14 support  (for Unicode Variant Selectors, UVS)
+      has been contributed by George Williams.
+
+    - A new face flag FT_FACE_FLAG_CID_KEYED has been added,  together
+      with a macro FT_IS_CID_KEYED which evaluates to 1 if the font is
+      CID-keyed.
+
+
+  III. MISCELLANEOUS
+
+    - Build support for symbian has been contributed.
+
+    - Better WGL4 glyph name support, contributed by Sergey Tolstov.
+
+    - Debugging output of the  various FT_TRACEX macros is now sent to
+      stderr.
+
+    - The `ftview' demo program now provides artificial slanting too.
+
+    - The `ftvalid' demo  program has a new  option `-f' to select the
+      font index.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.3.5 and 2.3.4
+
+  I. IMPORTANT BUG FIXES
+
+    - Some subglyphs in TrueType fonts were handled incorrectly due to
+      a missing graphics state reinitialization.
+
+    - Large .Z files  (as distributed with some X11  packages) weren't
+      handled correctly, making FreeType increase the heap stack in an
+      endless loop.
+
+    - A large  number of  bugs have  been fixed  to avoid  crashes and
+      endless loops with invalid fonts.
+
+
+  II. IMPORTANT CHANGES
+
+    - The  two new  cache functions  `FTC_ImageCache_LookupScaler' and
+      `FTC_SBit_Cache_LookupScaler' have been added to allow lookup of
+      glyphs using an  `FTC_Scaler' object;  this makes it possible to
+      use fractional pixel sizes in the cache.  The demo programs have
+      been updated accordingly to use this feature.
+
+    - A new API  `FT_Get_CMap_Format' has been added to  get the  cmap
+      format  of a  TrueType font.   This  is useful  in handling  PDF
+      files.  The code has been contributed by Derek Clegg.
+
+    - The  auto-hinter  now  produces  better  output  by  default for
+      non-Latin scripts  like Indic.   This was done by  using the CJK
+      hinting module  as the default instead of the Latin one.  Thanks
+      to Rahul Bhalerao for this suggestion.
+
+    - A new API `FT_Face_CheckTrueTypePatents'  has been added to find
+      out  whether  a  given  TrueType  font  uses  patented  bytecode
+      instructions.   The  `ft2demos' bundle  contains a  new  program
+      called `ftpatchk' which demonstrates its usage.
+
+    - A  new  API  `FT_Face_SetUnpatentedHinting'  has  been  added to
+      enable or disable the unpatented hinter.
+
+    - Support for Windows FON files in PE format  has been contributed
+      by Dmitry Timoshkov.
+
+
+  III. MISCELLANEOUS
+
+    - Vincent Richomme contributed Visual C++ project files for Pocket
+      PCs.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.3.4 and 2.3.3
+
+  I. IMPORTANT BUG FIXES
+
+    - A serious  bug  in  the  handling  of bitmap  fonts (and  bitmap
+      strikes of outline fonts) has been introduced in 2.3.3.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.3.3 and 2.3.2
+
+  I. IMPORTANT BUG FIXES
+
+    - Remove a serious regression in the TrueType bytecode interpreter
+      that was introduced  in version 2.3.2.  Note that  this does not
+      disable  the  improvements  introduced  to  the  interpreter  in
+      version 2.3.2,  only some ill  cases that occurred  with certain
+      fonts (though a few popular ones).
+
+    - The auto-hinter now  ignores single-point contours for computing
+      blue zones.   This bug  created `wavy' baselines  when rendering
+      text  with  various  fonts  that  use these  contours  to  model
+      mark-attach points  (these are points that  are never rasterized
+      and are placed outside of the glyph's real outline).
+
+    - The `rsb_delta' and `lsb_delta' glyph slot fields are now set to
+      zero for mono-spaced fonts.  Otherwise code that uses them would
+      essentially ruin the fixed-advance property.
+
+    - Fix  CVE-2007-1351 which  can  cause an  integer overflow  while
+      parsing  BDF fonts,  leading to  a potentially  exploitable heap
+      overflow condition.
+
+
+  II. MISCELLANEOUS
+
+    - Fixed compilation issues on some 64-bit platforms (see ChangeLog
+      for details).
+
+    - A new demo  program `ftdiff' has been added  to compare TrueType
+      hinting, FreeType's auto  hinting, and rendering without hinting
+      in three columns.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.3.2 and 2.3.1
+
+  I. IMPORTANT BUG FIXES
+
+    - FreeType  returned incorrect  kerning information  from TrueType
+      fonts when the bytecode  interpreter was enabled.  This happened
+      due to a typo introduced in version 2.3.0.
+
+    - Negative  kerning  values  from   PFM  files  are  now  reported
+      correctly  (they were read  as 16-bit  unsigned values  from the
+      file).
+
+    - Fixed  a small  memory leak  when `FT_Init_FreeType'  failed for
+      some reason.
+
+    - The Postscript hinter placed and sized very thin and ghost stems
+      incorrectly.
+
+    - The TrueType bytecode  interpreter has been fixed to  get rid of
+      most of the  rare differences seen in comparison  to the Windows
+      font loader.
+
+
+  II. IMPORTANT CHANGES
+
+    - The auto-hinter  now better deals  with serifs and  corner cases
+      (e.g.,  glyph '9'  in Arial  at 9pt,  96dpi).  It  also improves
+      spacing  adjustments and doesn't  change widths  for non-spacing
+      glyphs.
+
+    - Many   Mac-specific   functions   are  deprecated   (but   still
+      available);  modern replacements  have been  provided  for them.
+      See the documentation in file `ftmac.h'.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.3.1 and 2.3.0
+
+  I. IMPORTANT BUG FIXES
+
+    - The TrueType interpreter sometimes returned incorrect horizontal
+      metrics due to a bug in the handling of the SHZ instruction.
+
+    - A typo  in  a  security  check  introduced  after  version 2.2.1
+      prevented FreeType to render some glyphs in CFF fonts.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.3.0 and 2.2.1
+
+  I. IMPORTANT BUG FIXES
+
+    - The  PCF font  loader  is  now much  more  robust while  loading
+      malformed font files.
+
+    - Various memory leaks have been found and fixed.
+
+    - The TrueType name loader now deals properly with some fonts that
+      encode their  names in UTF-16 (the specification  was vague, and
+      the code incorrectly assumed UCS-4).
+
+    - Fixed the TrueType bytecode  loader to deal properly with subtle
+      monochrome/gray  issues  when   scaling  the  CVT.   Some  fonts
+      exhibited bad rendering artifacts otherwise.
+
+    - `FT_GlyphSlot_Embolden' now  supports vertical layouts correctly
+      (it mangled the vertical advance height).
+
+    - Fixed byte  endian issues  of `ftmac.c' to  support Mac OS  X on
+      i386.
+
+    - The  PFR  font loader  no  longer  erroneously  tags font  files
+      without any outlines as FT_FACE_FLAG_SCALABLE.
+
+
+  II. NEW API FUNCTIONS
+
+    - `FT_Library_SetLcdFilter' allows you  to select a special filter
+      to be  applied to the bitmaps generated  by `FT_Render_Glyph' if
+      one of the FT_RENDER_MODE_LCD and FT_RENDER_MODE_LCD_V modes has
+      been  selected.  This filter  is used  to reduce  color fringes;
+      several  settings are  available  through the  FT_LCD_FILTER_XXX
+      enumeration.
+
+      Its  declaration   and  documentation  can  be   found  in  file
+      `include/freetype/ftlcdfil.h'   (to  be   accessed   with  macro
+      FT_LCD_FILTER_H).
+
+      *IMPORTANT*:     This      function     returns     an     error
+      (FT_Err_Unimplemented_Feature) in default  builds of the library
+      for patent reasons.  See below.
+
+    - `FT_Get_Gasp'  allows you  to query  the flags  of  the TrueType
+      `gasp' table for  a given character pixel size.   This is useful
+      to duplicate  the text rendering  of MS Windows when  the native
+      bytecode  interpreter is  enabled (which  isn't the  default for
+      other patent reasons).
+
+      Its  declaration   and  documentation  can  be   found  in  file
+      `include/freetype/ftgasp.h'   (to   be   accessed   with   macro
+      FT_GASP_H).
+
+
+  III. IMPORTANT CHANGES
+
+    - The auto-hinter has been tuned a lot to improve its results with
+      serif fonts, resulting in much better font rendering of many web
+      pages.
+
+    - The unpatented  hinter is now part  of the default  build of the
+      library; we  have added  code to automatically  support `tricky'
+      fonts that need it.
+
+      This means  that FreeType should `just work'  with certain Asian
+      fonts, like  MingLiU, which cannot properly be  loaded without a
+      bytecode interpreter,  but which fortunately  do not use  any of
+      the patented  bytecode opcodes.  We detect these  fonts by name,
+      so please  report any font file  that doesn't seem  to work with
+      FreeType, and  we shall do what we  can to support it  in a next
+      release.
+
+      Note  that  the API  hasn't  changed,  so  you can  still  force
+      unpatented hinting with a special parameter to `FT_Open_Face' as
+      well.  This  might be useful in  same cases; for  example, a PDF
+      reader might present  a user option to activate  it to deal with
+      certain  `tricky'   embedded  fonts  which   cannot  be  clearly
+      identified.
+
+      If you are  a developer for embedded systems,  you might want to
+      *disable*  the   feature  to  save  code   space  by  undefining
+      TT_CONFIG_OPTION_UNPATENTED_HINTING in file `ftoption.h'.
+
+    - LCD-optimized rendering is now  *disabled* in all default builds
+      of  the  library,  mainly   due  to  patent  issues.   For  more
+      information see:
+
+      https://lists.gnu.org/archive/html/freetype/2006-09/msg00064.html
+
+      A  new  configuration macro  FT_CONFIG_OPTION_SUBPIXEL_RENDERING
+      has been introduced in  `ftoption.h'; manually define it in this
+      file if you want to re-enable the feature.
+
+      The  change only  affects the  implementation, not  the FreeType
+      API.  This means that clients don't need to be modified, because
+      the library still generates  LCD decimated bitmaps, but with the
+      added constraint that R=G=B on each triplet.
+
+      The  displayed result  should  be equal  to normal  anti-aliased
+      rendering.
+
+      Additionally,  if   FT_CONFIG_OPTION_SUBPIXEL_RENDERING  is  not
+      defined, the new  `FT_Library_SetLcdFilter' function returns the
+      FT_Err_Unimplemented_Feature error code.
+
+    - Some computation bugs in  the TrueType bytecode interpreter were
+      found,  which  allow us  to  get rid  of  very  subtle and  rare
+      differences we had experienced with the Windows renderer.
+
+    - It is now possible to cross-compile the library easily.  See the
+      file `docs/INSTALL.CROSS' for details.
+
+    - The file `src/base/ftmac.c' now contains code for Mac OS X only;
+      its  deprecated function  `FT_GetFile_From_Mac_Font_Name' always
+      returns an  error even if the QuickDraw  framework is available.
+      The previous version has been moved to `builds/mac/ftmac.c'.
+
+      Selecting  configure option `--with-quickdraw-carbon'  makes the
+      build process use the original `ftmac.c' file instead of the Mac
+      OS X-only version.
+
+
+  IV. MISCELLANEOUS
+
+    - Various performance and memory footprint optimizations have been
+      performed on  the TrueType and CFF font  loaders, sometimes with
+      very drastic  benefits (e.g., the  TrueType loader is  now about
+      25% faster;  FreeType should use  less heap memory  under nearly
+      all conditions).
+
+    - The anti-aliased rasterizer has been optimized and is now 15% to
+      25%  percent  faster than  in  previous  versions, depending  on
+      content.
+
+    - The Type 1 loader has been improved; as an example, it now skips
+      top-level dictionaries properly.
+
+    - Better support for Mac  fonts on POSIX systems, plus compilation
+      fixes for Mac OS X on ppc64 where `ftmac.c' cannot be built.
+
+    - Configuration  without `--with-old-mac-fonts'  does  not include
+      `ftmac.c' (this was the behaviour in FreeType version 2.1.10).
+
+    - The TrueTypeGX validator (gxvalid) checks the order of glyph IDs
+      in the kern table.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.2.1 and 2.2
+
+  I. IMPORTANT BUG FIXES
+
+    - Various integer overflows have been fixed.
+
+    - PFB fonts with MacOS resource fork weren't  handled correctly on
+      non-MacOS platforms.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.2 and 2.1.10
+
+(not released officially)
+
+  I. IMPORTANT BUG FIXES
+
+    - Vertical metrics for SFNT fonts were incorrect sometimes.
+
+    - The FT_HAS_KERNING macro always returned 0.
+
+    - CFF OpenType  fonts didn't  return correct vertical  metrics for
+      glyphs with outlines.
+
+    - If FreeType was compiled without hinters, all font formats based
+      on PS outlines weren't scaled correctly.
+
+
+  II. IMPORTANT CHANGES
+
+    - Version 2.2 no longer exposes its internals, this is, the header
+      files  located in  the `include/freetype/internal'  directory of
+      the source package are not  copied anymore by the `make install'
+      command.  Consequently, a number of rogue clients which directly
+      access  FreeType's  internal   functions  and  structures  won't
+      compile without modification.
+
+      We provide  patches for  most of those  rogue clients.   See the
+      following page for more information:
+
+        https://www.freetype.org/freetype2/patches/rogue-patches.html
+
+      Note that, as  a convenience to our Unix  desktop users, version
+      2.2 is *binary* compatible with FreeType 2.1.7, which means that
+      installing this  release on  an existing distribution  shall not
+      break any working desktop.
+
+    - FreeType's build  mechanism has been redesigned.   With GNU make
+      it  is  now  sufficient  in   most  cases  to  edit  two  files:
+      `modules.cfg',  to  select   the  library  components,  and  the
+      configuration  file  `include/freetype/config/ftoption.h' (which
+      can be copied to the objects directory).  Removing unused module
+      directories   to    prevent   its   compilation    and   editing
+      `include/freetype/config/ftmodule.h' is no longer necessary.
+
+    - The  LIGHT  hinting algorithm  produces  more pleasant  results.
+      Also, using the  FT_LOAD_TARGET_LIGHT flags within FT_Load_Glyph
+      always forces auto-hinting, as a special exception.  This allows
+      you to experiment with it  even if you have enabled the TrueType
+      bytecode interpreter in your build.
+
+    - The auto hinter now employs a new algorithm for CJK fonts, based
+      on Akito  Hirai's patch.   Note that this  only works  for fonts
+      with a Unicode charmap at the moment.
+
+    - The following callback function  types have changed slightly (by
+      adding the `const' keyword where appropriate):
+
+        FT_Outline_MoveToFunc
+        FT_Outline_LineToFunc
+        FT_Outline_ConicToFunc
+        FT_Outline_CubicToFunc
+        FT_SpanFunc
+        FT_Raster_RenderFunc
+
+        FT_Glyph_TransformFunc
+        FT_Renderer_RenderFunc
+        FT_Renderer_TransformFunc
+
+      Note that this doesn't affect binary backward compatibility.
+
+    - On MacOS,  new APIs have  been added as replacements  for legacy
+      APIs:  `FT_New_Face_From_FSRef'  for  `FT_New_Face_From_FSSpec',
+      and              `FT_GetFile_From_Mac_ATS_Name'              for
+      `FT_GetFile_From_Mac_Name'.  Legacy APIs are still available, if
+      FreeType is built without disabling them.
+
+    - A new  API `FT_Select_Size'  has been added  to select  a bitmap
+      strike  by its  index.   Code using  other  functions to  select
+      bitmap strikes should be updated to use this function.
+
+    - A  new API  `FT_Get_SubGlyph_Info'  has been  added to  retrieve
+      subglyph data.  This can be  used by rogue clients which used to
+      access the internal headers to get the corresponding data.
+
+    - In 2.1.10, the behaviour of `FT_Set_Pixel_Sizes' was changed for
+      BDF/PCF fonts,  and only  for them.  This  causes inconsistency.
+      In this release,  we undo the change.  The  intent of the change
+      in 2.1.10  is to allow  size selection through  real dimensions,
+      which can now be done through `FT_Request_Size'.
+
+    - Some security  issues were discovered  and fixed in the  CFF and
+      Type  1 loader, causing  crashes of  FreeType by  malformed font
+      files.
+
+
+  III. MISCELLANEOUS
+
+    - The documentation  for FT_LOAD_TARGET_XXX and FT_RENDER_MODE_XXX
+      values now better reflects its usage and differences: One set is
+      used to specify the hinting algorithm, the other to specify  the
+      pixel rendering mode.
+
+    - `FT_New_Face' and `FT_New_Face_From_FSSpec' in ftmac.c have been
+      changed to count supported scalable faces (sfnt, LWFN) only, and
+      to  return the  number of  available faces  via face->num_faces.
+      Unsupported bitmap faces (fbit, NFNT) are ignored.
+
+    - builds/unix/configure  has been  improved for  MacOS X.   It now
+      automatically checks available  functions in Carbon library, and
+      prepare to use newest  functions by default.  Options to specify
+      the  dependencies of  each Carbon  APIs (FSSpec,  FSRef, old/new
+      QuickDraw, ATS)  are available too.  By manual  disabling of all
+      QuickDraw   functionality,  FreeType   can   be  built   without
+      `deprecated   function'   warnings    on   MacOS   10.4.x,   but
+      FT_GetFile_Mac_Name  in  ftmac.c  then  is changed  to  a  dummy
+      function, and returns an `unimplemented' error.  For details see
+      builds/mac/README.
+
+    - SFNT cmap handling has been  improved, mainly to run much faster
+      with CJK fonts.
+
+    - A   new  function   `FT_Get_TrueType_Engine_Type   (declared  in
+      `FT_MODULE_H')  is  provided  to  determine the  status  of  the
+      TrueType   bytecode  interpreter   compiled  into   the  library
+      (patented, unpatented, unimplemented).
+
+    - Vertical metrics of glyphs are  synthesized if the font does not
+      provide such information.  You can tell whether  the metrics are
+      synthesized or not by checking the FT_FACE_FLAG_VERTICAL flag of
+      the face.
+
+    - The demo programs  `ftview' and  `ftstring' have been  rewritten
+      for better readability.   `ftview' has a new switch `-p' to test
+      FT_New_Memory_Face (instead of FT_New_Face).
+
+    - FreeType now honours bit 1 in the `head' table of TrueType fonts
+      (meaning `left sidebearing point at x=0').  This helps with some
+      buggy fonts.
+
+    - Rudimentary support for Adobe's new `SING Glyphlet' format.  See
+
+        https://www.adobe.com/content/dam/acom/en/devnet/font/pdfs/5148.SING_Tutorial.pdf
+
+      for more information.
+
+    - The `ftdump'  program from the `ft2demos' bundle  now shows some
+      information about charmaps.  It  also supports a new switch `-v'
+      to increase verbosity.
+
+    - Better AFM support.  This includes track kerning support.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.1.10 and 2.1.9
+
+  I. IMPORTANT BUG FIXES
+
+    - The size comparison for BDF and PCF files could fail sometimes.
+
+    - Some  CFF files  were still not  loaded  correctly.   Patch from
+      Derek Noonburg.
+
+    - The stroker still had some serious bugs.
+
+    - Boris  Letocha  fixed a  bug in  the  TrueType interpreter:  The
+      NPUSHW instruction wasn't skipped correctly in IF clauses.  Some
+      fonts like `Helvetica 75 Bold' failed.
+
+    - Another  serious  bug  in  handling  TrueType hints  caused many
+      distortions.  It has been introduced in version 2.1.8, and it is
+      highly recommended to upgrade.
+
+    - FreeType didn't properly parse empty Type 1 glyphs.
+
+    - An unbound dynamic buffer growth was fixed in the PFR loader.
+
+    - Several bugs have been fixed in the cache sub-system.
+
+    - FreeType behaved incorrectly when resizing two distinct but very
+      close character pixel sizes through `FT_Set_Char_Size' (Savannah
+      bug #12263).
+
+    - The auto-hinter didn't work properly for fonts without a Unicode
+      charmap -- it even refused to load the glyphs.
+
+
+  II. IMPORTANT CHANGES
+
+    - Many fixes have been applied to drastically reduce the amount of
+      heap   memory   used   by   FreeType,   especially   when  using
+      memory-mapped font files  (which is the default on Unix  systems
+      which support them).
+
+    - The auto-hinter  has been replaced with a new module, called the
+      `auto-fitter'.  It consumes  less memory  than its  predecessor,
+      and it is  prepared to support non-latin scripts  better in next
+      releases.
+
+    - George Williams  contributed code to read  kerning data from PFM
+      files.
+
+    - FreeType   now   uses    the   TT_NAME_ID_PREFERRED_FAMILY   and
+      TT_NAME_ID_PREFERRED_SUBFAMILY   strings   (if   available)  for
+      setting  family  and  style in SFNT  fonts  (patch from Kornfeld
+      Eliyahu Peter).
+
+    - A  new  API `FT_Sfnt_Table_Info'  (in FT_TRUETYPE_TABLES_H)  has
+      been added to retrieve name and size information of SFNT tables.
+
+    - A new API `FT_OpenType_Validate' (in FT_OPENTYPE_VALIDATE_H) has
+      been added to validate OpenType tables  (BASE, GDEF, GPOS, GSUB,
+      JSTF).   After validation  it is  no longer  necessary to  check
+      for errors in those tables while accessing them.
+
+      Note that  this module might  be moved to another library in the
+      future  to avoid  a tight  dependency between  FreeType and  the
+      OpenType specification.
+
+    - A new API in FT_BITMAP_H  (`FT_Bitmap_New', `FT_Bitmap_Convert',
+      `FT_Bitmap_Copy',  `FT_Bitmap_Embolden',  `FT_Bitmap_Done')  has
+      been added.   Its  use is  to convert an  FT_Bitmap structure in
+      1bpp, 2bpp,  4bpp, or 8bpp  format into  another 8bpp FT_Bitmap,
+      probably using a different pitch, and to further manipulate it.
+
+    - A new  API `FT_Outline_Embolden'  (in FT_OUTLINE_H) gives  finer
+      control how outlines are emboldened.
+
+    - `FT_GlyphSlot_Embolden' (in FT_SYNTHESIS_H)  now handles bitmaps
+      also (code contributed  by Chia I Wu).  Note that this  function
+      is still experimental and may be replaced with a better API.
+
+    - The method  how BDF and PCF  bitmap fonts  are accessed has been
+      refined.   Formerly,   FT_Set_Pixel_Sizes  and  FT_Set_Char_Size
+      were  synonyms in  FreeType's  BDF and PCF interface.  This  has
+      changed now.  FT_Set_Pixel_Sizes  should be  used to  select the
+      actual  font dimensions  (the `strike',  which is the sum of the
+      `FONT_ASCENT'    and    `FONT_DESCENT'    properties),     while
+      FT_Set_Char_Size  selects  the  `nominal' size  (the `PIXELSIZE'
+      property).  In both functions, the width parameter is ignored.
+
+
+  III. MISCELLANEOUS
+
+    - The BDF driver  no longer converts  all returned bitmaps  with a
+      depth of 2bpp or 4bpp to a depth of 8bpp.  The documentation has
+      not  mentioned  this  explicitly,  but  implementors  might have
+      relied on this after looking into the source files.
+
+    - A new option `--ftversion' has been  added to freetype-config to
+      return the FreeType version.
+
+    - The  memory  debugger  has  been  updated   to  dump  allocation
+      statistics on  all allocation  sources in the library.   This is
+      useful to  spot greedy  allocations when  loading and processing
+      fonts.
+
+    - We removed a huge array of constant pointers to constant strings
+      in the `psnames' module.   The problem was that  compilations in
+      PIC mode (i.e.,  when generating a  Unix shared object/dll)  put
+      the array  into the non-shared  writable section of  the library
+      since absolute pointers are not relocatable by nature.
+
+      This reduces the memory consumption by approximately 16KByte per
+      process linked  to FreeType.   We now also store  the array in a
+      compressed form (as a trie) which saves about 20KByte of code as
+      well.
+
+    - Kirill  Smelkov provided  patches to make  src/raster/ftraster.c
+      compile stand-alone again.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.1.9 and 2.1.8
+
+  I. IMPORTANT BUG FIXES
+
+    - The function  `FT_Get_CharMap_Index' was only declared,  without
+      any  real  code.   For  consistency,  it  has  been  renamed  to
+      `FT_Get_Charmap_Index'.   (This function is needed  to implement
+      cmap caches.)
+
+    - `FT_Outline_Get_BBox'  sometimes returned  incorrect values  for
+      conic outlines (e.g., for TrueType fonts).
+
+    - Handling of `bhed' table has been fixed.
+
+    - The TrueType driver with enabled byte code interpreter sometimes
+      returned artifacts due to incorrect rounding.  This bug has been
+      introduced after version 2.1.4.
+
+    - The BDF driver dropped the last glyph in the font.
+
+    - The BDF driver now uses the DEFAULT_CHAR property (if available)
+      to select a glyph shape for the undefined glyph.
+
+    - The stroker failed for closed outlines and single points.
+
+
+  II. IMPORTANT CHANGES
+
+    - George  Williams   contributed  code  to   handle  Apple's  font
+      distortion technology found in GX fonts (`avar', `cvar', `fvar',
+      and `gvar' tables;  the Multiple Masters  API has been  slightly
+      extended to cope with the new functionality).
+
+    - The `FT_GlyphSlotRec' structure has been extended:  The elements
+      `lsb_delta' and  `rsb_delta' give the difference  between hinted
+      and  unhinted  left and right  side bearings  if autohinting  is
+      active.  Using those values can improve the inter-letter spacing
+      considerably.   See the documentation of  `FT_GlyphSlotRec'  and
+      the `ftstring' demo program how to use it.
+
+    - Loading TrueType and Type 1 fonts has been made much faster.
+
+    - The stroker is  no longer experimental (but the  cache subsystem
+      still is).
+
+
+  III. MISCELLANEOUS
+
+    - A new  documentation file  `formats.txt' describes various  font
+      formats supported (and not supported) by FreeType.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.1.8 and 2.1.7
+
+  I. IMPORTANT BUG FIXES
+
+    - The native  TrueType hinter contained some  bugs which prevented
+      some fonts to be rendered correctly, most notably Legendum.otf.
+
+    - The PostScript hinter now produces improved results.
+
+    - The  linear advance  width  and height  values were  incorrectly
+      rounded,  making  them virtually  unusable  if  not loaded  with
+      FT_LOAD_LINEAR_DESIGN.
+
+    - Indexing CID-keyed CFF fonts is  now working: The glyph index is
+      correctly  treated as a  CID, similar  to FreeType's  CID driver
+      module.  Note that CID CMap support is still missing.
+
+    - The FT_FACE_FLAG_GLYPH_NAMES flag  is now  set correctly for all
+      font formats.
+
+    - Some subsetted Type 1  fonts weren't parsed correctly.  This bug
+      has been introduced in 2.1.7.  In summary, the Type 1 parser has
+      become more robust.
+
+    - Non-decimal numbers weren't parsed correctly in PS fonts.
+
+    - The WinFNT driver now correctly reports FT_ENCODING_NONE for all
+      but one encoding.  Use  the new FT_WinFNT_ID_XXX values together
+      with `FT_Get_WinFNT_Header' to get the WinFNT charset ID.
+
+    - The descender metrics (face->size->metrics.descender) for WinFNT
+      bitmap fonts had the wrong sign.
+
+    - The (emulated) `seac' support for CFF fonts was broken.
+
+    - The `flex' operator didn't work for CFF fonts.
+
+    - PS glyphs  which  use  the   `hintmask'  operator  haven't  been
+      rendered correctly in some cases.
+
+    - Metrics for BDF and PCF bitmap font formats have been fixed.
+
+    - Autohinting  is now  disabled for  glyphs  which  are vertically
+      distorted  or mirrored  (using a  transformation matrix).   This
+      fixes a bug which produced zero-height glyphs.
+
+    - The   `freetype-config'   script   now  handles   --prefix   and
+      --exec-prefix correctly; it also  returns the proper --rpath (or
+      -R) value if FreeType has been built as a shared library.
+
+
+  II. IMPORTANT CHANGES
+
+    - Both  PCF  and BDF  drivers  now  handle  the SETWIDTH_NAME  and
+      ADD_STYLE_NAME    properties.     Values    are   appended    to
+      face->style_name; example: `Bold SemiCondensed'.
+
+    - The PCF driver now handles bitmap  fonts compressed with the LZW
+      algorithm (extension .pcf.Z, compressed with `compress').
+
+    - A  new  API   function  `FT_Get_CMap_Language_ID'  (declared  in
+      `tttables.h')  is  available  to   get  the  language  ID  of  a
+      TrueType/SFNT cmap.
+
+    - The hexadecimal format of  data after the `StartData' command in
+      CID-keyed Type 1 fonts is now supported.  While this can't occur
+      in  file-based   fonts,  it  can   happen  in  document-embedded
+      resources of PostScript documents.
+
+    - Embedded bitmaps in SFNT-based CFF fonts are now supported.
+
+    - A simple  API is  now available  to control  FreeType's  tracing
+      mechanism if compiled  with FT_DEBUG_LEVEL_TRACE.   See the file
+      `ftdebug.h' for more details.
+
+    - YAMATO Masatake contributed improved  handling of MacOS resource
+      forks on non-MacOS platforms (for example, Linux can mount MacOS
+      file systems).
+
+    - Support for MacOS has been improved; there is now a new function
+      `FT_New_Face_From_FSSpec'  similar to `FT_New_Face'  except that
+      it accepts an FSSpec instead of a path.
+
+    - The cache sub-system has been rewritten.
+
+      - There is now support for deinstallation of faces.
+
+      - A new  API function `FTC_Manager_RemoveFaceID'  has been added
+        to  delete  all  `idle'  nodes  that  correspond  to  a  given
+        FTC_FaceID.  All `locked' nodes  (i.e., those with a reference
+        count > 0), will be modified to prevent them from appearing in
+        further  lookups (they  will  be cleaned  normally when  their
+        reference count reaches 0).
+
+      - There  is  now  support  for point  scaling  (i.e.,  providing
+        character sizes in points + dpis, instead of pixels).
+
+      - Three abstract cache classes are now available:
+
+          FTC_GCache:  Used to store  one glyph  item per  cache node,
+                      with the ability to group common attributes into
+                      `families'.      This    replaces     the    old
+                      FTC_GlyphCache class.
+
+          FTC_ICache: Used to store one FT_Glyph per cache node.  This
+                      extends  FTC_GCache.  Family  definition, family
+                      comparison, and  glyph loading are  however left
+                      to sub-classes.
+
+          FTC_SCache: Used to  store up to 16 small  bitmaps per cache
+                      node.    This    extends   FTC_GCache.    Family
+                      definition, family  comparison and glyph loading
+                      are however left to sub-classes.
+
+      - The file `src/cache/ftcbasic.c' implements:
+
+          FTC_ImageCache: Extends    FTC_ICache;   implements   family
+                          definitions and glyph loading similar to the
+                          old API.
+
+          FTC_SBitCache: Extends    FTC_SCache,    implements   family
+                         definitions and glyph  loading similar to the
+                         old API
+
+        Client  applications  should  be  able to  extend  FTC_GCache,
+        FTC_ICache, or FTC_SCache much more easily (i.e., less code to
+        write, and  less callbacks).  For example,  one could envision
+        caches  that are  capable of  storing  transformed (obliqued),
+        stroked,   emboldened,   or   colored   glyph   images.    Use
+        `ftcbasic.c' as an example.
+
+      - All public  APIs are now  in `include/freetype/ftcache.h', (to
+        be    accessed   as    `FT_CACHE_H').     The   contents    of
+        `include/freetype/cache/' is only  needed by applications that
+        wish to implement their own caches.
+
+      - There were some major performance improvements through the use
+        of  various programming  tricks.   Cache hits  are  up to  70%
+        faster than in the old code.
+
+      - The  FTC_CMapCache has  been simplified.  Charmaps can only be
+        accessed by  index right now.  There  is also a  new API named
+        `FT_Charmap_GetIndex' for this purpose.
+
+      - The  demo programs  have been  updated to  the new  code.  The
+        previous versions will not work with the current one.
+
+      - Using  an invalid face  index in FT_Open_Face and friends  now
+        causes an error even if the font contains a single face only.
+
+
+  III. MISCELLANEOUS
+
+    - Wolfgang Domröse contributed support files for building FreeType
+      on the Atari using the PureC compiler.  Note that the Atari is a
+      16bit platform.
+
+    - Vitaliy Pasternak contributed project files for VS.NET 2003.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.1.7 and 2.1.6
+
+  I. IMPORTANT BUG FIXES
+
+    - Updated  to newest  libtool  version, fixing  build problems  on
+      various platforms.
+
+    - On  Unix  platforms,  `make  install' didn't  copy  the  correct
+      `ftconfig.h' file.
+
+  Note that version 2.1.7  contains the same library  C source code as
+  version 2.1.6.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.1.6 and 2.1.5
+
+  I. IMPORTANT BUG FIXES
+
+    - The PFR  font driver didn't  load kerning tables  correctly, and
+      the functions in FT_PFR_H didn't work at all.
+
+    - Type 1 font  files in  binary format  (PFB) with  an end-of-file
+      indicator weren't accepted by the FreeType engine.
+
+    - Fonts which contain /PaintType  and /StrokeWidth no longer cause
+      a segfault.  This bug has been introduced in version 2.1.5.
+
+    - Fonts  loaded  with   FT_LOAD_RENDER  no  longer  cause  strange
+      results.  This bug has been introduced in version 2.1.5.
+
+    - Some  Windows   (bitmap)  FNT/FON  files   couldn't  be  handled
+      correctly.
+
+
+  II. IMPORTANT CHANGES
+
+    - The internal  module API  has been heavily  changed in  favor of
+      massive simplifications within the font engine.  This also means
+      that authors of third-party modules must adapt their code to the
+      new scheme.
+
+      NOTE:  THE NEW SCHEME IS NOT COMPLETED YET.  PLEASE WAIT UNTIL A
+      FINAL ANNOUNCEMENT!
+
+    - The PostScript  parser has been enhanced to  handle comments and
+      strings   correctly.   Additionally,   more  syntax   forms  are
+      recognized.
+
+    - Added the  optional unpatented hinting system  for TrueType.  It
+      allows  typefaces which  need hinting  to produce  correct glyph
+      forms (e.g., Chinese typefaces  from Dynalab) to work acceptably
+      without infringing Apple patents.   This system is compiled only
+      if  TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING  is  defined  in
+      ftoption.h (activated by default).
+
+
+  III. MISCELLANEOUS
+
+    - There  is now  a guard  in the  public header  files  to protect
+      against inclusion of freetype.h from FreeType 1.
+
+    - Direct inclusion of freetype.h  and other public header files no
+      longer works.  You have to use the documented scheme
+
+        #include <ft2build.h>
+        #include FT_FREETYPE_H
+
+      to load freetype.h with  a symbolic name.  This protects against
+      renaming  of public  header  files (which  shouldn't happen  but
+      actually  has, avoiding two  public header  files with  the same
+      name).
+
+
+======================================================================
+
+CHANGES BETWEEN 2.1.5 and 2.1.4
+
+  I. IMPORTANT BUG FIXES
+
+    - Parsing the /CIDFontName field  now removes the leading slash to
+      be in sync with other font drivers.
+
+    - gzip support was buggy.  Some fonts could not be read.
+
+    - Fonts which  have nested subglyphs  more than one level  deep no
+      longer cause a segfault.
+
+    - Creation of synthetic  cmaps for fonts in CFF  format was broken
+      partially.
+
+    - Numeric  font  dictionary entries  for  synthetic  fonts are  no
+      longer overwritten.
+
+    - The font matrix  wasn't applied to the advance  width for Type1,
+      CID, and  CFF fonts.  This caused problems  when loading certain
+      synthetic Type 1 fonts like `Helvetica Narrow'.
+
+    - The test  for the charset registry  in BDF and PCF  fonts is now
+      case-insensitive.
+
+    - FT_Vector_Rotate  sometimes  returned   strange  values  due  to
+      rounding errors.
+
+    - The  PCF  driver  now  returns  the  correct  number  of  glyphs
+      (including an artificial `notdef' glyph at index 0).
+
+    - FreeType now  supports buggy CMaps  which are contained  in many
+      CJK fonts from Dynalab.
+
+    - Opening  an invalid  font  on a  Mac  caused a  segfault due  to
+      double-freeing memory.
+
+    - BDF  fonts  with  more   than  32768  glyphs  weren't  supported
+      properly.
+
+
+  II. IMPORTANT CHANGES
+
+    - Accessing bitmap font formats has been synchronized.  To do that
+      the FT_Bitmap_Size  structure has  been extended to  contain new
+      fields `size', `x_ppem', and `y_ppem'.
+
+    - The FNT driver now returns multiple faces, not multiple strikes.
+
+    - The `psnames'  module has been  updated to the Adobe  Glyph List
+      version 2.0.
+
+    - The `psnames' module now understands `uXXXX[X[X]]' glyph names.
+
+    - The algorithm for guessing the font style has been improved.
+
+    - For fonts in SFNT format, root->height is no longer increased if
+      the line gap  is zero.  There exist fonts  (containing e.g. form
+      drawing  characters) which  intentionally have  a zero  line gap
+      value.
+
+    - ft_glyph_bbox_xxx  flags   are  now  deprecated   in  favour  of
+      FT_GLYPH_BBOX_XXX.
+
+    - ft_module_xxx   flags   are   now   deprecated  in   favour   of
+      FT_MODULE_XXX.
+
+    - FT_ENCODING_MS_{SJIS,GB2312,BIG5,WANSUNG,JOHAB}      are     now
+      deprecated               in               favour              of
+      FT_ENCODING_{SJIS,GB2312,BIG5,WANSUNG,JOHAB}  -- those encodings
+      are not specific to Microsoft.
+
+
+  III. MISCELLANEOUS
+
+    - The  autohinter  has been  further  improved;  for example,  `m'
+      glyphs now retain its vertical symmetry.
+
+    - Partial support of Mac fonts on non-Mac platforms.
+
+    - `make   refdoc'   (after   first   `make')   builds   the   HTML
+      documentation.  You need Python for this.
+
+    - The make build system should  now work more reliably on DOS-like
+      platforms.
+
+    - Support for  EMX gcc  and Watson C/C++  compilers on  MS-DOS has
+      been added.
+
+    - Better VMS build support.
+
+    - Support for the pkg-config  package by providing a `freetype.pc'
+      file.
+
+    - New configure option --with-old-mac-fonts for Darwin.
+
+    - Some source files have been  renamed (mainly to fit into the 8.3
+      naming scheme).
+
+
+======================================================================
+
+CHANGES BETWEEN 2.1.4 and 2.1.3
+
+  I. IMPORTANT BUG FIXES
+
+    - Updated  to newest  libtool  version, fixing  build problems  on
+      various platforms.
+
+    - A fix  in the Gzip stream  reader: It couldn't  read certain .gz
+      files properly due to a  small typo.  In certain cases, FreeType
+      could  also loop  endlessly  when trying  to  load tiny  gzipped
+      files.
+
+    - The configure script now tries  to use the system-wide zlib when
+      it  finds one  (instead of  the  copy found  in src/gzip).   And
+      `freetype-config' has  been updated to return  relevant flags in
+      this case when invoked with `--libs' (e.g. `-lzlib').
+
+    - Certain fonts couldn't be loaded  by 2.1.3 because they lacked a
+      Unicode   charmap  (e.g.   SYMBOL.TTF).    FreeType  erroneously
+      rejected them.
+
+    - The CFF loader was modified to accept fonts which only contain a
+      subset of  their reference charset.  This  prevented the correct
+      use of PDF-embedded fonts.
+
+    - The logic to detect Unicode charmaps has been modified.  This is
+      required to  support fonts which include both  16-bit and 32-bit
+      charmaps (like very  recent asian ones) using the  new 10 and 12
+      SFNT formats.
+
+    - The TrueType  loader now limits  the depth of  composite glyphs.
+      This is necessary to prevent broken fonts to break the engine by
+      blowing the stack with recursive glyph definitions.
+
+    - The CMap cache is now  capable of managing UCS-4 character codes
+      that   are   mapped   through   extended  charmaps   in   recent
+      TrueType/OpenType fonts.
+
+    - The   cache  sub-system   now  properly   manages  out-of-memory
+      conditions  instead of  blindly  reporting them  to the  caller.
+      This means that it will try to empty the cache before restarting
+      its allocations to see if that can help.
+
+    - The  PFR driver  didn't return  the list  of  available embedded
+      bitmaps properly.
+
+    - There was  a nasty  memory leak when  using embedded  bitmaps in
+      certain font formats.
+
+
+  II. IMPORTANT CHANGES
+
+    - David Chester  contributed some enhancements  to the auto-hinter
+      that  significantly increase  the  quality of  its output.   The
+      Postscript hinter was also improved in several ways.
+
+    - The FT_RENDER_MODE_LIGHT render mode was implemented.
+
+    - A new  API function called `FT_Get_BDF_Property'  has been added
+      to FT_BDF_H to  retrieve BDF properties from BDF  _and_ PCF font
+      files.   THIS  IS  STILL  EXPERIMENTAL,  since  it  hasn't  been
+      properly tested yet.
+
+    - A Windows FNT specific API has been added, mostly to access font
+      headers.  This is used by Wine.
+
+    - TrueType tables  without an `hmtx' table are  now tolerated when
+      an  incremental interface  is  used.  This  happens for  certain
+      Type42 fonts passed from Ghostscript to FreeType.
+
+    - The PFR font driver is  now capable of returning the font family
+      and style  names when  they are available  (instead of  the sole
+      `FontID').   This  is  performed  by parsing  an  *undocumented*
+      portion of the font file!
+
+
+  III. MISCELLANEOUS
+
+    - The path stroker in FT_STROKER_H has entered beta stage.  It now
+      works very  well, but  its interface might  change a bit  in the
+      future.  More on this in later releases.
+
+    - The documentation for  FT_Size_Metrics didn't appear properly in
+      the API reference.
+
+    - The file docs/VERSION.DLL has been updated to explain versioning
+      with FreeType  (i.e., comparing release/libtool/so  numbers, and
+      how to use them in autoconf scripts).
+
+    - The  installation  documentation  has been  seriously  revamped.
+      Everything is now in the `docs' directory.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.1.3 and 2.1.2
+
+  I. IMPORTANT BUG FIXES
+
+    - FT_Vector_Transform  had  been  incorrectly modified  in  2.1.2,
+      resulting  in  incorrect   transformations  being  applied  (for
+      example, rotations were processed in opposite angles).
+
+    - The format  8 and 12 TrueType charmap  enumeration routines have
+      been fixed (FT_Get_Next_Char returned invalid values).
+
+    - The  PFR font driver  returned incorrect  advance widths  if the
+      outline  and metrics resolution  defined in  the font  file were
+      different.
+
+    - FT_Glyph_To_Bitmap now returns  successfully when called with an
+      FT_BitmapGlyph argument (it previously returned an error).
+
+    - A bug  in the Type 1  loader that prevented  valid font bounding
+      boxes to be loaded from multiple master fonts.
+
+    - The SFNT  validation code has been rewritten.   FreeType can now
+      load `broken'  fonts that were  usable on Windows, but  not with
+      previous versions of the library.
+
+    - The computation of bearings in the BDF driver has been fixed.
+
+    - The Postscript hinter crashed when trying to hint certain glyphs
+      (more precisely,  when trying to  apply hints to an  empty glyph
+      outline).
+
+    - The  TrueType glyph  loader  now supports  composites in  `Apple
+      format'  (they differ slightly  from Microsoft/OpenType  ones in
+      the way transformation offsets are computed).
+
+    - FreeType was  very slow at opening certain  asian CID/CFF fonts,
+      due to  fixed increment  in dynamic array  re-allocations.  This
+      has  been changed  to  exponential behaviour  to get  acceptable
+      performance.
+
+
+
+  II. IMPORTANT CHANGES
+
+    - The PCF driver now supports gzip-compressed font files natively.
+      This means that  you will be able to use  all these bitmap fonts
+      that  come with  XFree86 with  FreeType (and  libXft/libXft2, by
+      extension).
+
+    - The  automatic and  postscript hinters  have both  been updated.
+      This  results in  a relatively  important increase  of rendering
+      quality since  many nasty defaults have been suppressed.  Please
+      visit the web page:
+
+        https://www.freetype.org/hinting/smooth-hinting.html
+
+      for additional details on this topic.
+
+    - The `load_flags' parameter of `FT_Load_Glyph' is now an FT_Int32
+      (instead  of just  being  an FT_Int).   This  breaks source  and
+      binary  compatibility for  16bit systems  only,  while retaining
+      both of them for 32 and 64 bit ones.
+
+      Some new flags have been added consequently:
+
+        FT_LOAD_NO_AUTOHINT   :: Disable the use of the auto-hinter
+                                 (but not native format hinters).
+
+        FT_LOAD_TARGET_NORMAL :: Hint and render for normal
+                                 anti-aliased displays.
+
+        FT_LOAD_TARGET_MONO   :: Hint and render for 1-bit displays.
+
+        FT_LOAD_TARGET_LCD    :: Hint and render for horizontal RGB or
+                                 BGR subpixel displays (like LCD
+                                 screens).  THIS IS STILL
+                                 EXPERIMENTAL!
+
+        FT_LOAD_TARGET_LCD_V  :: Same as FT_LOAD_TARGET_LCD, for
+                                 vertical subpixel displays (like
+                                 rotated LCD screens).  THIS IS STILL
+                                 EXPERIMENTAL!
+
+      FT_LOAD_MONOCHROME   is  still   supported,  but   only  affects
+      rendering, not the hinting.
+
+      Note that the `ftview'  demo program available in the `ft2demos'
+      package  has been  updated to  support LCD-optimized  display on
+      non-paletted displays (under Win32 and X11).
+
+    - The  PFR  driver  now  supports embedded  bitmaps  (all  formats
+      supported), and returns correct kerning metrics for all glyphs.
+
+    - The TrueType charmap loader  now supports certain `broken' fonts
+      that load under Windows without problems.
+
+    - The cache API has been slightly modified (it's still a beta!):
+
+       - The type  FTC_ImageDesc has been removed; it  is now replaced
+         by  FTC_ImageTypeRec.   Note that  one  of  its  fields is  a
+         `load_flag' parameter for FT_Load_Glyph.
+
+       - The  field  `num_grays' of  FT_SBitRec  has  been changed  to
+         `max_grays'  in  order to  fit  within  a  single byte.   Its
+         maximum value is thus 255 (instead of 256 as previously).
+
+
+  III. MISCELLANEOUS
+
+    - Added support  for the  DESTDIR variable during  `make install'.
+      This simplifies packaging of FreeType.
+
+    - Included modified  copies of the  ZLib sources in  `src/gzip' in
+      order to support  gzip-compressed PCF fonts.  We do  not use the
+      system-provided  zlib  for  now,   though  this  is  a  probable
+      enhancement for future releases.
+
+    - The DocMaker tool used to generate the on-line API reference has
+      been   completely    rewritten.    It   is    now   located   in
+      `src/tools/docmaker/docmaker.py'.  Features:
+
+        - better cross-referenced output
+        - more polished output
+        - uses Python regular expressions  (though it didn't speed the
+          program)
+        - much  more  modular structure,  which  allows for  different
+          `backends'  in  order to  generate  HTML,  XML, or  whatever
+          format.
+
+      One can regenerate the API reference by calling:
+
+         python src/tools/docmaker/docmaker.py \
+                --prefix=ft2 \
+                --title=FreeType-2.1.3 \
+                --output=<outputdirectory>
+                include/freetype/*.h \
+                include/freetype/config/*.h \
+                include/freetype/cache/*.h
+
+    - A new, experimental, support for incremental font loading (i.e.,
+      loading  of fonts  where the  glyphs are  not in  the  font file
+      itself, but provided by an external component, like a Postscript
+      interpreter) has been added by Graham Asher.  This is still work
+      in progress, however.
+
+    - A new,  EXPERIMENTAL, path stroker  has been added.   It doesn't
+      suffer  from  severe  rounding  errors  and  treat  bezier  arcs
+      directly.  Still work in progress (i.e. not part of the official
+      API).   See  the file  <freetype/ftstroker.h>  for  some of  the
+      details.
+
+    - The massive  re-formatting of sources and  internal re-design is
+      still under-way.  Many  internal functions, constants, and types
+      have been renamed.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.1.2 and 2.1.1
+
+  I. IMPORTANT BUG FIXES
+
+    - Many  font drivers didn't  select a  Unicode charmap  by default
+      when a new face  was opened (with the FT_CONFIG_OPTION_USE_CMAPS
+      options enabled),  causing many applications  to not be  able to
+      display text correctly with the 2.1.x releases.
+
+    - The  PFR driver had  a bug  in its  composite loading  code that
+      produces incorrectly placed accents with many fonts.
+
+    - The Type42 driver crashed sometimes due to a nasty bug.
+
+    - The Type 1 custom encoding  charmap didn't handle the case where
+      the first glyph index wasn't 0.
+
+    - A  serious  typo  in  the  TrueType  composite  loader  produced
+      incorrectly placed  glyphs in fonts  like `Wingdings' and  a few
+      others.
+
+
+  II. MISCELLANEOUS
+
+    - The Win32  Visual C++ project  file has been updated  to include
+      the PFR driver as well.
+
+    - `freetype.m4' is  now installed by default by  `make install' on
+      Unix systems.
+
+    - The function  FT_Get_PS_Font_Info now works with  CID and Type42
+      fonts as well.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.1.1 and 2.1.0
+
+  I. IMPORTANT BUG FIXES
+
+    - The  `version_info'  returned   by  `freetype-config'  in  2.1.0
+      returned an invalid value.  It now returns 9:1:3 (2.0.9 returned
+      9:0:3).
+
+    - Version 2.1.0  couldn't be linked against  applications on Win32
+      and  Amiga systems  due  to  a new  debug  function that  wasn't
+      properly   propagated  to   the  system-specific   directory  in
+      `builds'.
+
+    - Various MacOS and Mac OS X specific fixes.
+
+    - Fixed  a bug in  the TrueType  charmap validation  routines that
+      made version  2.1.0 too restrictive  -- many popular  fonts have
+      been rejected.
+
+    - There was  still a very small difference  between the monochrome
+      glyph bitmaps produced by FreeType 1.x and FreeType 2.x with the
+      bytecode  interpreter enabled.   This was  caused by  an invalid
+      flag setting in the TrueType glyph loader, making the rasterizer
+      change  its  drop-out   control  mode.   Now  the results should
+      _really_ be completely identical.
+
+    - The TrueType name table loader has been improved to support many
+      popular  though buggy Asian  fonts.  It  now ignores  empty name
+      entries,  invalid  pointer offsets  and  a  few other  incorrect
+      subtleties.  Moreover,  name strings  are now loaded  on demand,
+      which reduces the memory load  of many faces (e.g. the ARIAL.TTF
+      font file contains a 10kByte name table with 70 names).
+
+    - Fixed a bug in the Postscript hinter that prevented family blues
+      substitution to happen correctly.
+
+
+  II. NEW FEATURES
+
+    - Three new font drivers in this release:
+
+      * A  BDF  font driver,  contributed  by  Franco Zappa  Nardelli,
+        heavily  modified   by  Werner  Lemberg.    It  also  supports
+        anti-aliased bitmaps (using a slightly extended BDF format).
+
+      * A Type42  font driver, contributed by Roberto  Alameda.  It is
+        still experimental but seems to work relatively well.
+
+      * A PFR  font driver, contributed  by David Turner  himself.  It
+        doesn't  support PFR  hinting --  note that  BitStream  has at
+        least two patents on this format!
+
+
+  III. MISCELLANEOUS
+
+    - The  cache  sub-system has  been  optimized  in important  ways.
+      Cache hits are now significantly faster.  For example, using the
+      CMap cache is about  twice faster than calling FT_Get_Char_Index
+      on most platforms.  Similarly, using an SBit cache is about five
+      times faster  than loading the  bitmaps from a bitmap  file, and
+      300 to  500 times  faster than generating  them from  a scalable
+      format.
+
+      Note that  you should recompile  your sources if you  designed a
+      custom  cache  class for  the  FT2  Cache  subsystem, since  the
+      changes performed are source, but not binary, compatible.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.1.0 and 2.0.9
+
+  I. IMPORTANT BUG FIXES
+
+    - The  TrueType bytecode  interpreter  has been  fixed to  produce
+      _exactly_ the same output as FreeType 1.x.  Previous differences
+      were due  to slightly distinct  fixed-point computation routines
+      used to perform dot products and vector length measurements.
+
+      It seems  that native TrueType hinting  is _extremely_ sensitive
+      to  rounding errors.  The  required vector  computation routines
+      have been optimized and placed within the `ttinterp.c' file.
+
+    - Fixed the parsing of accelerator tables in the PCF font driver.
+
+    - Fixed the Type1 glyph loader  routine used to compute the font's
+      maximum advance width.
+
+
+  II. NEW FEATURES
+
+    - The `configure' script used on Unix systems has been modified to
+      check  that  GNU  Make  is  being used  to  build  the  library.
+      Otherwise,  it  will display  a  message  proposing  to use  the
+      GNUMAKE environment variable to name it.
+
+      The Unix-specific file README.UNX has been modified accordingly.
+
+
+  III. MISCELLANEOUS
+
+    - The  FreeType  License in  `docs/FTL.TXT'  has  been updated  to
+      include  a  proposed preferred  disclaimer.   If  you are  using
+      FreeType in your products, you are encouraged (but not mandated)
+      to use the following text in your documentation:
+
+      """
+        Portions of this software are copyright © 1996-2002 The
+        FreeType Project (www.freetype.org).  All rights reserved.
+      """
+
+    - The default size of the render pool has been reduced to 16kByte.
+      This  shouldn't result  in any  noticeable  performance penalty,
+      unless you are  using the engine as-is to  render very large and
+      complex glyphs.
+
+    - The  FreeType 2  redesign has  begun.  More  information  can be
+      found at this URL:
+
+        https://www.freetype.org/freetype2/redesign.html
+
+      The following  internal changes  have been performed  within the
+      sources of this release:
+
+        - Many   internal  types   have  been   renamed   to  increase
+          consistency.   The  following  should  be true,  except  for
+          public types:
+
+            * All structure  types have a name ending  in `Rec' (short
+              for `record').
+
+            * A  pointer-to-structure type  has the  same name  as the
+              structure, _without_ the `Rec' suffix.
+
+              Example:
+
+                typedef struct FooRec_
+                {
+                  ...
+
+                } FooRec, *Foo;
+
+        - Many   internal  macros  have   been  renamed   to  increase
+          consistency.  The following should be true:
+
+            * All  macros  have a  name  beginning  with `FT_'.   This
+              required a few changes like
+
+                ALLOC   => FT_ALLOC
+                FREE    => FT_FREE
+                REALLOC => FT_REALLOC
+
+            * All  macros are completely  UPPERCASE.  This  required a
+              few changes like:
+
+                READ_Short  => FT_READ_SHORT
+                NEXT_Short  => FT_NEXT_SHORT
+                GET_ULongLE => FT_GET_ULONG_LE
+                MEM_Set     => FT_MEM_SET
+                MEM_Copy    => FT_MEM_COPY
+                etc.
+
+            * Whenever   possible,   all   macro  names   follow   the
+              FT_<OBJECT>_<METHOD> pattern.  For example
+
+                ACCESS_Frame   => FT_FRAME_ENTER
+                FORGET_Frame   => FT_FRAME_EXIT
+                EXTRACT_Frame  => FT_FRAME_EXTRACT
+                RELEASE_Frame  => FT_FRAME_RELEASE
+
+                FILE_Pos       => FT_STREAM_POS
+                FILE_Seek      => FT_STREAM_SEEK
+                FILE_Read      => FT_STREAM_READ
+                FILE_ReadAt    => FT_STREAM_READ_AT
+                READ_Fields    => FT_STREAM_READ_FIELDS
+
+        - Many  internal functions  have  been renamed  to follow  the
+          FT_<Object>_<Method> pattern.  For example:
+
+            FT_Seek_Stream       => FT_Stream_Seek
+            FT_Read_Stream_At    => FT_Stream_ReadAt
+            FT_Done_Stream       => FT_Stream_Close
+            FT_New_Stream        => FT_Stream_Open
+            FT_New_Memory_Stream => FT_Stream_OpenMemory
+            FT_Extract_Frame     => FT_Stream_ExtractFrame
+
+          Note that method names do not contain `_'.
+
+        - The FT_ALLOC_ARRAY  and FT_REALLOC_ARRAY have  been replaced
+          with  FT_NEW_ARRAY and  FT_RENEW_ARRAY which  do not  take a
+          type  as the  fourth argument.   Instead, the  array element
+          type  size is computed  automatically from  the type  of the
+          target pointer used.
+
+        - A  new object  class, FT_CMap,  has been  introduced.  These
+          internal  objects are  used to  model character  maps.  This
+          eases  the support  of additional  charmap types  within the
+          engine.
+
+        - A new  configuration file named `ftstdlib.h'  has been added
+          to `include/freetype/config'.  It  is used to define aliases
+          for  _every_ routine  of the  ISO  C library  that the  font
+          engine   uses.    Each    aliases   has   a   `ft_'   prefix
+          (e.g. `ft_strlen' is an alias for `strlen').
+
+          This is  used to  ease the porting  of FreeType 2  to exotic
+          runtime environments where the ISO C Library isn't available
+          (e.g.  XFree86 extension modules).
+
+      More details are available in the `ChangeLog' file.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.0.9 and 2.0.8
+
+  I. IMPORTANT BUG FIXES
+
+    - Certain fonts like `foxjump.ttf' contain broken name tables with
+      invalid entries and wild offsets.  This caused FreeType to crash
+      when trying to load them.
+
+      The  SFNT `name'  table  loader has  been  fixed to  be able  to
+      support these strange fonts.
+
+      Moreover, the code  in charge of processing this  table has been
+      changed  to always favour  Windows-formatted entries  over other
+      ones.  Hence,  a font that works  on Windows but not  on the Mac
+      will  load cleanly in  FreeType and  report accurate  values for
+      Family & PostScript names.
+
+    - The CID font driver has been fixed.  It unfortunately returned a
+      Postscript   Font   name   with   a   leading   slash,   as   in
+      `/MunhwaGothic-Regular'.
+
+    - FreeType  2 should now  compile fine  on AIX  4.3.3 as  a shared
+      library.
+
+    - A  bug  in the  Postscript  hinter  has  been found  and  fixed,
+      removing un-even stem widths at small pixel sizes (like 14-17).
+
+      This  improves the  quality of  a certain  number  of Postscript
+      fonts.
+
+
+  II. NEW FEATURES
+
+    - A  new function  named  `FT_Library_Version' has  been added  to
+      return  the current  library's major,  minor, and  patch version
+      numbers.   This is  important since  the  macros FREETYPE_MAJOR,
+      FREETYPE_MINOR,  and  FREETYPE_PATCH  cannot  be used  when  the
+      library is dynamically linked by a program.
+
+    - Two   new  APIs   have  been   added:   `FT_Get_First_Char'  and
+      `FT_Get_Next_Char'.
+
+      Together,  these can  be used  to iterate  efficiently  over the
+      currently  selected  charmap of  a  given  face.   Read the  API
+      reference for more details.
+
+
+  III. MISCELLANEOUS
+
+    - The FreeType sources are  under heavy internal re-factoring.  As
+      a consequence,  we have created  a branch named `STABLE'  on the
+      CVS to hold all future releases/fixes in the 2.0.x family.
+
+      The  HEAD  branch  now  contains  the  re-factored  sources  and
+      shouldn't  be used for  testing or  packaging new  releases.  In
+      case you  would like  to access the  2.0.9 sources from  our CVS
+      repository, use the tag `VER-2-0-9'.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.0.8 and 2.0.7
+
+  I. IMPORTANT BUG FIXES
+
+    - There was  a small but  nasty bug in  `freetype-config.in' which
+      caused the `freetype-config' script to fail on Unix.
+
+      This didn't prevent the installation  of the library or even its
+      execution, but caused problems  when trying to compile many Unix
+      packages that depend on it.
+
+    - Some TrueType or OpenType fonts embedded in PDF documents do not
+      have  a  'cmap',  'post'  and  'name'  as  is  required  by  the
+      specification.  FreeType no longer refuses to load such fonts.
+
+    - Various fixes to the PCF font driver.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.0.7 and 2.0.6
+
+  I. IMPORTANT BUG FIXES
+
+    - Fixed  two  bugs in  the  Type 1  font  driver.   The first  one
+      resulted in a memory leak in subtle cases.  The other one caused
+      FreeType to crash when  trying to load `.gsf' files (Ghostscript
+      so-called Postscript fonts).
+
+      (This  made _many_  KDE applications  crash on  certain systems.
+       FreeType _is_ becoming a critical system component on Linux :-)
+
+    - Fixed a memory leak in the CFF font driver.
+
+    - Fixed a memory leak in the PCF font driver.
+
+    - Fixed       the        Visual       C++       project       file
+      `builds/win32/visualc/freetype.dsp' since  it didn't include the
+      Postscript hinter component, causing errors at build time.
+
+    - Fixed a  small rendering bug  in the anti-aliased  renderer that
+      only  occurred when  trying to  draw  thin (less  than 1  pixel)
+      strokes.
+
+    - Fixed  `builds/unix/freetype2.a4' which  is used  to  generate a
+      valid `freetype2.m4' for use with autoconf.
+
+    - Fixed the OpenVMS Makefiles.
+
+
+  II. MISCELLANEOUS
+
+    - Added  `configure'  and   `install'  scripts  to  the  top-level
+      directory.  A GNU-style installation is thus now easily possible
+      with
+
+        ./configure  <options>
+        make
+        make install
+
+
+======================================================================
+
+CHANGES BETWEEN 2.0.6 and 2.0.5
+
+  I. IMPORTANT BUG FIXES
+
+    - It wasn't possible to load embedded bitmaps when the auto-hinter
+      was used.  This is now fixed.
+
+    - The TrueType  font driver  didn't load some  composites properly
+      (the  sub-glyphs  were  slightly  shifted,  and  this  was  only
+      noticeable when using monochrome rendering).
+
+    - Various  fixes  to the  auto-hinter.   They  merely improve  the
+      output of sans-serif fonts.   Note that there are still problems
+      with serifed fonts and composites (accented characters).
+
+    - All scalable  font drivers erroneously  returned un-fitted glyph
+      advances when hinting was  requested.  This created problems for
+      a number  of layout applications.  This  is a very  old bug that
+      got  undetected mainly  because most  test/demo  program perform
+      rounding explicitly or implicitly (through the cache).
+
+    - `FT_Glyph_To_Bitmap' did erroneously  modify the source glyph in
+      certain cases.
+
+    - `glnames.py'  still contained  a bug  that made  FreeType return
+      invalid names for certain glyphs.
+
+    - The  library crashed  when  loading certain  Type  1 fonts  like
+      `sadn.pfb'  (`Stalingrad  Normal'),   which  appear  to  contain
+      pathetic font info dictionaries.
+
+    - The TrueType glyph  loader is now much more  paranoid and checks
+      everything when loading a given glyph image.  This was necessary
+      to avoid problems (crashes and/or memory overwrites) with broken
+      fonts that came from a really buggy automatic font converter.
+
+
+  II. IMPORTANT UPDATES AND NEW FEATURES
+
+    - Important updates to the Mac-specific parts of the library.
+
+    - The caching sub-system has  been completely re-designed, and its
+      API has  evolved (the  old one is  still supported  for backward
+      compatibility).
+
+      The documentation for it is  not yet completed, sorry.  For now,
+      you are encouraged to continue  using the old API.  However, the
+      ftview  demo program in  the ft2demos  package has  already been
+      updated to use the new caching functions.
+
+    - A new charmap cache is provided too.  See `FTC_CMapCache'.  This
+      is useful to perform  character code -> glyph index translations
+      quickly, without the need for an opened FT_Face.
+
+    - A NEW POSTSCRIPT HINTER module  has been added to support native
+      hints in  the following  formats: PostScript Type  1, PostScript
+      CID, and CFF/CEF.
+
+      Please test!  Note that  the auto-hinter produces better results
+      for a number of  badly-hinted fonts (mostly auto-generated ones)
+      though.
+
+    - A memory debugger is now  part of the standard FreeType sources.
+      To      enable      it,      define      FT_DEBUG_MEMORY      in
+      <freetype/config/ftoption.h>, and recompile the library.
+
+      Additionally, define  the _environment_ variable FT_DEBUG_MEMORY
+      and run any program using FreeType.  When the library is exited,
+      a  summary  of memory  footprints  and  possible  leaks will  be
+      displayed.
+
+      This works transparently with  _any_ program that uses FreeType.
+      However, you  will need a lot  of memory to  use this (allocated
+      blocks are never  released to the heap to  detect double deletes
+      easily).
+
+
+  III. MISCELLANEOUS
+
+    - We  are  aware  of  subtle  differences between  the  output  of
+      FreeType  versions   1  and  2  when  it   comes  to  monochrome
+      TrueType-hinted glyphs.   These are  most probably due  to small
+      differences in the monochrome rasterizers and will be worked out
+      in an upcoming release.
+
+    - We have decided to fork the sources in a `stable' branch, and an
+      `unstable' one, since FreeType  is becoming a critical component
+      of many Unix systems.
+
+      The next  bug-fix releases of  the library will be  named 2.0.7,
+      2.0.8, etc.,  while the `2.1'  branch will contain a  version of
+      the sources where we will start major reworking of the library's
+      internals, in order to produce FreeType 2.2.0 (or even 3.0) in a
+      more distant future.
+
+      We  also hope  that this  scheme will  allow much  more frequent
+      releases than in the past.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.0.5 and 2.0.4
+
+  NOTE THAT 2.0.5 DOES NOT CONTAIN THE POSTSCRIPT HINTER.  THIS MODULE
+  WILL BE PART OF THE NEXT RELEASE (EITHER 2.0.6 or 2.1)
+
+  - Fixed a bug that made  certain glyphs, like `Cacute', `cacute' and
+    `lslash'  unavailable from Unicode  charmaps of  Postscript fonts.
+    This prevented the correct display of Polish text, for example.
+
+  - The kerning table of Type 1 fonts was loaded by FreeType, when its
+    AFM    file    was    attached    to    its    face,    but    the
+    FT_FACE_FLAG_HAS_KERNING   bit  flags   was  not   set  correctly,
+    preventing FT_Get_Kerning to return meaningful values.
+
+  - Improved  SFNT (TrueType  & OpenType)  charmap  support.  Slightly
+    better performance, as well as support for the new formats defined
+    by the OpenType 1.3 specification (8, 10, and 12)
+
+  - Fixed a  serious typo in `src/base/ftcalc.c'  which caused invalid
+    computations in certain rare cases, producing ugly artefacts.
+
+  - The  size  of the  EM  square is  computed  with  a more  accurate
+    algorithm for Postscript fonts.   The old one caused slight errors
+    with embedded fonts found in PDF documents.
+
+  - Fixed  a  bug in  the  cache  manager  that prevented  normal  LRU
+    behaviour  within the cache  manager, causing  unnecessary reloads
+    (for FT_Face and FT_Size objects only).
+
+  - Added  a new  function named  `FT_Get_Name_Index' to  retrieve the
+    glyph index of a given glyph name, when found in a face.
+
+  - Added  a new function  named `FT_Get_Postscript_Name'  to retrieve
+    the `unique' Postscript font name of a given face.
+
+  - Added   a   new   public   header  size   named   FT_SIZES_H   (or
+    <freetype/ftsizes.h>) providing  new FT_Size-management functions:
+    FT_New_Size, FT_Activate_Size, FT_Done_Size.
+
+  - Fixed a  reallocation bug that  generated a dangling  pointer (and
+    possibly    memory    leaks)    with    Postscript    fonts    (in
+    src/psaux/psobjs.c).
+
+  - Many fixes for 16-bit correctness.
+
+  - Removed many pedantic compiler warnings from the sources.
+
+  - Added an Amiga build directory in `builds/amiga'.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.0.4 and 2.0.3
+
+  - Fixed a rather annoying bug that was introduced in 2.0.3.  Namely,
+    the font  transformation set through  FT_Set_Transform was applied
+    twice to auto-hinted glyphs, resulting in incorrectly rotated text
+    output.
+
+  - Fixed _many_  compiler warnings.   FT2 should now  compile cleanly
+    with Visual  C++'s most pedantic warning level  (/W4).  It already
+    compiled fine with GCC and a few other compilers.
+
+  - Fixed a bug  that prevented the linear advance  width of composite
+    TrueType glyphs to be correctly returned.
+
+  - Fixed    the    Visual    C++    project    files    located    in
+    `builds/win32/visualc' (previous versions  used older names of the
+    library).
+
+  - Many  32-bit constants  have an  `L' appended  to their  value, in
+    order to improve the 16-bitness  of the code.  Someone is actually
+    trying to use FT2 on an Atari ST machine!
+
+  - Updated  the  `builds/detect.mk' file  in  order to  automatically
+    build FT2  on AIX systems.   AIX uses `/usr/sbin/init'  instead of
+    `/sbin/init' and wasn't previously  detected as a Unix platform by
+    the FreeType build system.
+
+  - Updated  the  Unix-specific  portions  of the  build  system  (new
+    libtool version, etc.).
+
+  - The  SFNT kerning  loader now  ensures  that the  table is  sorted
+    (since some problem fonts do not meet this requirement).
+
+
+=======================================================================
+
+CHANGES BETWEEN 2.0.3 and 2.0.2
+
+  I. CHANGES TO THE MODULES / FONT DRIVERS
+
+    - THE  AUTO-HINTER HAS  BEEN SLIGHTLY  IMPROVED, in  order  to fix
+      several annoying artefacts, mainly:
+
+        - Blue  zone alignment  of  horizontal stems  wasn't performed
+          correctly, resulting in artefacts  like the `d' being placed
+          one pixel below the `b' in some fonts like Time New Roman.
+
+        - Overshoot thresholding  wasn't performed correctly, creating
+          unpleasant artefacts at large character pixel sizes.
+
+        - Composite glyph loading has  been simplified.  This gets rid
+          of  various artefacts  where the  components of  a composite
+          glyphs were not correctly spaced.
+
+      These are  the last changes to the  current auto-hinting module.
+      A new  hinting sub-system is currently  in the work  in order to
+      support native hints  in Type 1 / CFF /  OpenType fonts, as well
+      as globally improve rendering.
+
+    - The  PCF  driver has  been  fixed.   It  reported invalid  glyph
+      dimensions for the fonts available on Solaris.
+
+    - The Type  1, CID and CFF  drivers have been modified  to fix the
+      computation of the EM size.
+
+    - The Type 1  driver has been fixed to avoid  a dangerous bug that
+      crashed the library with non-conforming fonts (i.e. ones that do
+      not place the .notdef glyph at position 0).
+
+    - The TrueType  driver had a  rather subtle bug  (dangling pointer
+      when loading  composite glyphs) that could crash  the library in
+      rare occasions!
+
+
+  II. HIGH-LEVEL API CHANGES
+
+    - The error  code enumeration values have been  changed.  An error
+      value  is decomposed  in  a  generic error  code,  and a  module
+      number.  see <freetype/fterrors.h> for details.
+
+    - A   new  public   header   file  has   been  introduced,   named
+      FT_TRIGONOMETRY_H    (include/freetype/fttrigon.h),    providing
+      trigonometric functions to  compute sines, cosines, arctangents,
+      etc. with 16.16 fixed precision.  The implementation is based on
+      the CORDIC  algorithm and is very fast  while being sufficiently
+      accurate.
+
+
+  III. INTERNALS
+
+    - Added  BeOS-specific files  in the  old build  sub-system.  Note
+      that no changes were required to compile the library with Jam.
+
+    - The  configuration  is now  capable  of automatically  detecting
+      64-bit integers  on a set  of predefined compilers  (GCC, Visual
+      C++, Borland C++) and will use them by default.  This provides a
+      small performance boost.
+
+    - A  small memory leak  that happened  when opening  0-sized files
+      (duh!)  have been fixed.
+
+    - Fixed bezier  stack depth  bug in the  routines provided  by the
+      FT_BBOX_H  header   file.   Also  fixed  similar   bugs  in  the
+      rasterizers.
+
+    - The outline bounding  box code has been rewritten  to use direct
+      computations,  instead of  bezier sub-division,  to  compute the
+      exact bounding box of glyphs.   This is slightly slower but more
+      accurate.
+
+    - The build system has been  improved and fixed, mainly to support
+      `make'  on Windows  2000  correctly, avoid  problems with  `make
+      distclean' on non Unix systems, etc.
+
+    - Hexadecimal  constants  have been  suffixed  with  `U' to  avoid
+      problems with certain compilers on 64-bit platforms.
+
+    - A new directory named `src/tools' has been created.  It contains
+      Python scripts and simple unit test programs used to develop the
+      library.
+
+    - The DocMaker tool has been  moved from `docs' to `src/tools' and
+      has been updated with the following:
+
+         - Now accepts the `--title=XXXX' or `-t XXXX' option from the
+           command line to set the project's name in the generated API
+           reference.
+
+         - Now accepts the `--output=DIR'  or `-o DIR' option from the
+           command line to set  the output directory for all generated
+           HTML files.
+
+         - Now accepts the `--prefix=XXXX' or `-p XXX' option from the
+           command  line  to  set  the  file prefix  to  use  for  all
+           generated HTML files.
+
+         - Now generates the current  time/data on each generated page
+           in order to distinguish between versions.
+
+      DocMaker  can be  used with  other  projects now,  not only  FT2
+      (e.g. MLib, FTLayout, etc.).
+
+
+======================================================================
+
+CHANGES BETWEEN 2.0.2 and 2.0.1
+
+  I. CHANGES TO THE MODULES / FONT DRIVERS
+
+    - THE TRUETYPE BYTECODE INTERPRETER IS NOW TURNED OFF, in order to
+      avoid legal problems  with the Apple patents.  It  seems that we
+      mistakenly  turned this option  on in  previous releases  of the
+      build.
+
+      Note that if  you want to use the  bytecode interpreter in order
+      to get high-quality TrueType  rendering, you will need to toggle
+      by        hand        the        definition        of        the
+      TT_CONFIG_OPTION_BYTECODE_INTERPRETER   macro    in   the   file
+      `include/freetype/config/ftoption.h'.
+
+    - The CFF driver has been improved by Tom Kacvinsky and Sander van
+      der Wal:
+
+      * Support for `seac' emulation.
+      * Support for `dotsection'.
+      * Support for retrieving glyph names through
+        `FT_Get_Glyph_Name'.
+
+      The first two items are necessary to correctly a large number of
+      Type 1 fonts converted to the CFF formats by Adobe Acrobat.
+
+    - The Type 1 driver was also improved by Tom & others:
+
+      * Better EM size computation.
+      * Better support for synthetic (transformed) fonts.
+      * The  Type 1  driver returns  the charstrings  corresponding to
+        each glyph in the  `glyph->control_data' field after a call to
+        `FT_Load_Glyph' (thanks Ha Shao).
+
+    - Various other bugfixes, including the following:
+
+      * Fixed a nasty memory leak in the Type 1 driver.
+      * The autohinter  and the pcf  driver used static  writable data
+        when they shouldn't.
+      * Many casts were added to  make the code more 64-bits safe.  It
+        also now compiles on Windows XP 64-bits without warnings.
+      * Some incorrect writable statics were removed in the `autohint'
+        and `pcf' drivers.  FreeType 2 now compiles on Epoc again.
+
+
+  II. CHANGES TO THE HIGH-LEVEL API
+
+    - The library header files inclusion scheme has been changed.  The
+      old scheme looked like:
+
+        #include <freetype/freetype.h>
+        #include <freetype/ftglyph.h>
+        #include <freetype/ftcache.h>
+        #include <freetype/cache/ftimage.h>
+
+      Now you should use:
+
+        #include <ft2build.h>
+        #include FT_FREETYPE_H
+        #include FT_GLYPH_H
+        #include FT_CACHE_H
+        #include FT_CACHE_IMAGE_H
+
+      NOTE THAT  THE OLD  INCLUSION SCHEME WILL  STILL WORK  WITH THIS
+      RELEASE.  HOWEVER, WE  DO NOT GUARANTEE THAT THIS  WILL STILL BE
+      TRUE IN THE NEXT ONE (A.K.A. FREETYPE 2.1).
+
+      The  file <ft2build.h>  is used  to define  the  header filename
+      macros.  The complete and  commented list of macros is available
+      in the API reference under the section name `Header File Macros'
+      in Chapter I.
+
+      For more information, see section I of the following document:
+
+        https://www.freetype.org/freetype2/docs/tutorial/step1.html
+
+    - Many, many comments have been added to the public source file in
+      order to  automatically generate  the API Reference  through the
+      `docmaker.py' Python script.
+
+      The latter has been updated  to support the grouping of sections
+      in chapters and better index sort.  See:
+
+        https://www.freetype.org/freetype2/docs/reference/ft2-toc.html
+
+
+  III. CHANGES TO THE BUILD PROCESS
+
+    - If you  are not  building FreeType 2  with its own  build system
+      (but with your own Makefiles or project files), you will need to
+      be  aware that  the  build  process has  changed  a little  bit.
+
+      You don't  need to put the  `src' directory in  the include path
+      when  compiling  any FT2  component.   Instead,  simply put  the
+      component's directory in the current include path.
+
+      So, if you were doing something like:
+
+        cc -c -Iinclude -Isrc src/base/ftbase.c
+
+      change the line to:
+
+        cc -c -Iinclude -Isrc/base src/base/ftbase.c
+
+      If you were doing something like:
+
+        cd src/base
+        cc -c -I../../include -I.. ftbase.c
+
+      change it to:
+
+        cd src/base
+        cc -c -I../../include ftbase.c
+
+
+======================================================================
+
+CHANGES BETWEEN 2.0.1 and 2.0
+
+  2.0.1 introduces a few changes:
+
+    - Fixed many bugs related to  the support of CFF / OpenType fonts.
+      These  formats are  now much  better supported  though  there is
+      still work planned to  deal with charset tables and PDF-embedded
+      CFF files that use the old `seac' command.
+
+    - The  library could not  be compiled  in debug  mode with  a very
+      small  number   of  C  compilers   whose  pre-processors  didn't
+      implement the `##'  directive correctly (i.e. per se  the ANSI C
+      specification!)  An elegant fix was found.
+
+    - Added  support for  the  free Borland  command-line C++  Builder
+      compiler.   Use `make  setup bcc32'.   Also fixed  a  few source
+      lines that generated new warnings with BCC32.
+
+    - Fixed a bug in FT_Outline_Get_BBox when computing the extrema of
+      a conic Bezier arc.
+
+    - Updated the INSTALL file to add IDE compilation.
+
+    - Other  minor bug  fixes,  from  invalid Type  1  style flags  to
+      correct   support   of  synthetic   (obliqued)   fonts  in   the
+      auto-hinter, better support for embedded bitmaps in a SFNT font.
+
+    - Fixed some problems with `freetype-config'.
+
+  Finally, the `standard' scheme for including FreeType headers is now
+  gradually changing,  but this will  be explained in a  later release
+  (probably 2.0.2).
+
+  And very  special thanks to Tom Kacvinsky  and YAMANO-UCHI Hidetoshi
+  for their contributions!
+
+
+======================================================================
+
+CHANGES BETWEEN beta8 and 2.0
+
+  - Changed  the default  installation  path for  public headers  from
+    `include/freetype' to `include/freetype2'.
+
+    Also added a new `freetype-config' that is automatically generated
+    and installed  on Unix and  Cygwin systems.  The script  itself is
+    used to retrieve the current  install path, C compilation flags as
+    well as linker flags.
+
+  - Fixed several small bugs:
+
+    * Incorrect max advance width for fixed-pitch Type 1 fonts.
+    * Incorrect glyph names for certain TrueType fonts.
+    * The  glyph advance  was not  copied when  FT_Glyph_To_Bitmap was
+      called.
+    * The  linearHoriAdvance  and  linearVertAdvance  fields  were not
+      correctly returned for glyphs processed by the auto-hinter.
+    * `type1z'  renamed back to  `type1'; the  old `type1'  module has
+      been removed.
+
+  - Revamped the  build system  to make it  a lot more  generic.  This
+    will  allow us  to  re-use  nearly un-modified  in  lots of  other
+    projects (including FreeType Layout).
+
+  - Changed `cid' to use `psaux' too.
+
+  - Added the  cache sub-system.  See <freetype/ftcache.h>  as well as
+    the sources  in `src/cache'.  Note  that it compiles but  is still
+    untested for now.
+
+  - Updated `docs/docmaker.py', a draft  API reference is available at
+    http://www.freetype.org/ft2api.html.
+
+  - Changed `type1' to use `psaux'.
+
+  - Created a  new module named  `psaux' to hold  the Type 1 &  Type 2
+    parsing routines.  It should be  used by `type1', `cid', and `cff'
+    in the future.
+
+  - Fixed an important bug in `FT_Glyph_Get_CBox'.
+
+  - Fixed  some compiler  warnings  that happened  since the  TrueType
+    bytecode decoder was deactivated by default.
+
+  - Fixed two memory leaks:
+
+    * The    memory   manager   (16    bytes)   isn't    released   in
+      FT_Done_FreeType!
+    * Using custom input streams, the  copy of the original stream was
+      never released.
+
+  - Fixed the  auto-hinter by performing automatic  computation of the
+    `filling direction' of each glyph.   This is done through a simple
+    and  fast approximation, and  seems to  work (problems  spotted by
+    Werner though).  The Arphic fonts are a lot nicer though there are
+    still a lot of things to do to handle Asian fonts correctly.
+
+
+======================================================================
+
+BETA-8 (RELEASE CANDIDATE) CHANGES
+
+  - Deactivated the TrueType bytecode interpreter by default.
+
+  - Deactivated the `src/type1' font driver.  Now `src/type1z' is used
+    by default.
+
+  - Updates to the build system.  We now compile the library correctly
+    under  Unix  system  through  `configure' which  is  automatically
+    called on the first `make' invocation.
+
+  - Added the auto-hinting module!  Fixing some bugs here and there.
+
+  - Found some bugs in the  composite loader (seac) of the Type1-based
+    font drivers.
+
+  - Renamed the directory `freetype2/config' to `freetype2/builds' and
+    updated all relevant files.
+
+  - Found a memory leak in the `type1' driver.
+
+  - Incorporated Tom's patches to  support flex operators correctly in
+    OpenType/CFF fonts.  Now all I need is to support pure CFF and CEF
+    fonts to be done with this driver :-)
+
+  - Added the  Windows FNT/FON driver in `src/winfonts'.   For now, it
+    always  `simulates'   a  Unicode  charmap,  so   it  shouldn't  be
+    considered completed right now.
+
+    It  is there  to be  more a  proof of  concept than  anything else
+    anyway.  The driver is a single  C source file, that compiles to 3
+    Kb of code.
+
+    I'm  still working on  the PCF/BDF  drivers, but  I'm too  lazy to
+    finish them now.
+
+  - CHANGES TO THE HIGH-LEVEL API
+
+    * FT_Get_Kerning has a new parameter that allows you to select the
+      coordinates of the kerning  vector (font units, scaled, scaled +
+      grid-fitted).
+    * The  outline functions are  now in <freetype/ftoutln.h>  and not
+      part of <freetype/freetype.h> anymore.
+    * <freetype/ftmodule.h>    now     contains    declarations    for
+       FT_New_Library, FT_Done_Library, FT_Add_Default_Modules.
+    * The so-called convenience  functions have moved from `ftoutln.c'
+      to  `ftglyph.c',  and  are  thus available  with  this  optional
+      component    of   the   library.     They   are    declared   in
+      <freetype/ftglyph.h> now.
+    * Anti-aliased  rendering is now  the default  for FT_Render_Glyph
+      (i.e. corresponds to render_mode == 0 == ft_render_mode_normal).
+      To generate a monochrome bitmap, use ft_render_mode_mono, or the
+      FT_LOAD_MONOCHROME     flag    in    FT_Load_Glyph/FT_Load_Char.
+      FT_LOAD_ANTI_ALIAS is still defined, but values to 0.
+    * <freetype/freetype.h>  now include <freetype/config/ftconfig.h>,
+      solving a few headaches :-)
+    * The type FT_GlyphSlotRec has now a `library' field.
+
+  - CHANGES TO THE `ftglyph.h' API
+
+    This API has  been severely modified in order  to make it simpler,
+    clearer, and more  efficient.  It certainly now looks  like a real
+    `glyph factory'  object, and allows client  applications to manage
+    (i.e.  transform,  bbox  and  render) glyph  images  without  ever
+    knowing their original format.
+
+  - Added  support  for CID-keyed  fonts  to  the  CFF driver.   Maybe
+    support for pure CFF + CEF fonts should come in?
+
+  - Cleaned up  source code in order  to avoid two  functions with the
+    same name.  Also  changed the names of the  files in `type1z' from
+    `t1XXXX' to `z1XXXX' in order to avoid any conflicts.
+
+    `make multi' now works well :-)
+
+    Also removed the use of `cidafm' for now, even if the source files
+    are  still there.  This  functionality will  certainly  go into  a
+    specific module.
+
+  - ADDED SUPPORT FOR THE AUTO-HINTER
+
+    It  works :-) I  have a  demo program  which simply  is a  copy of
+    `ftview'       that      does       a      `FT_Add_Module(library,
+    &autohinter_module_class)' after  library initialization, and Type
+    1 & OpenType/CFF fonts are now hinted.
+
+    CID  fonts are  not hinted,  as they  include no  charmap  and the
+    auto-hinter doesn't include  `generic' global metrics computations
+    yet.
+
+    Now, I need to release this thing to the FreeType 2 source.
+
+  - CHANGES TO THE RENDERER MODULES
+
+    The  monochrome  and smooth  renderers  are  now  in two  distinct
+    directories, namely `src/raster1' and `src/smooth'.  Note that the
+    old `src/renderer' is now gone.
+
+    I ditched  the 5-gray-levels renderers.  Basically,  it involved a
+    simple #define toggle in 'src/raster1/ftraster.c'.
+
+    FT_Render_Glyph,  FT_Outline_Render  &  FT_Outline_Get_Bitmap  now
+    select the best renderer  available, depending on render mode.  If
+    the current renderer for a  given glyph image format isn't capable
+    of supporting  the render mode, another  one will be  found in the
+    library's list.   This means that client applications  do not need
+    to  switch or  set  the  renderers themselves  (as  in the  latest
+    change), they'll get what they want automatically.  At last.
+
+    Changed the demo programs accordingly.
+
+  - MAJOR INTERNAL REDESIGN:
+
+    A lot of internal modifications  have been performed lately on the
+    source in order to provide the following enhancements:
+
+    * More generic module support:
+
+      The FT_Module  type is  now defined to  represent a handle  to a
+      given  module.   The  file  <freetype/ftmodule.h>  contains  the
+      FT_Module_Class definition, as well as the module-loading public
+      API.
+
+      The  FT_Driver type  is still  defined, and  still  represents a
+      pointer to  a font driver.  Note that  FT_Add_Driver is replaced
+      by FT_Add_Module, FT_Get_Driver by FT_Get_Module, etc.
+
+    * Support for generic glyph image types:
+
+      The FT_Renderer  type is a pointer  to a module  used to perform
+      various operations on glyph image.
+
+      Each renderer is  capable of handling images in  a single format
+      (e.g. ft_glyph_format_outline).  Its functions are used to:
+
+      - transform an glyph image
+      - render a glyph image into a bitmap
+      - return the control box (dimensions) of a given glyph image
+
+      The scan converters `ftraster.c' and `ftgrays.c' have been moved
+      to the new directory `src/renderer', and are used to provide two
+      default renderer modules.
+
+      One corresponds  to the `standard' scan-converter,  the other to
+      the `smooth' one.
+
+      he  current  renderer  can  be  set  through  the  new  function
+      FT_Set_Renderer.
+
+      The old raster-related function FT_Set_Raster, FT_Get_Raster and
+      FT_Set_Raster_Mode have now disappeared, in favor of the new:
+
+        FT_Get_Renderer
+        FT_Set_Renderer
+
+      See the file <freetype/ftrender.h> for more details.
+
+      These  changes  were  necessary  to properly  support  different
+      scalable formats in the future, like bi-color glyphs, etc.
+
+    * Glyph loader object:
+
+      A  new  internal  object,  called  a  'glyph  loader'  has  been
+      introduced in the base layer.  It is used by all scalable format
+      font drivers to load glyphs and composites.
+
+      This object  has been  created to reduce  the code size  of each
+      driver,  as  each  one  of  them  basically  re-implemented  its
+      functionality.
+
+      See <freetype/internal/ftobjs.h> and the FT_GlyphLoader type for
+      more information.
+
+    * FT_GlyphSlot has new fields:
+
+      In  order   to  support  extended  features   (see  below),  the
+      FT_GlyphSlot structure has a few new fields:
+
+      linearHoriAdvance:
+
+        This  field  gives  the   linearly  scaled  (i.e.  scaled  but
+        unhinted) advance  width for the  glyph, expressed as  a 16.16
+        fixed pixel value.  This is useful to perform WYSIWYG text.
+
+      linearVertAdvance:
+        This field  gives the linearly  scaled advance height  for the
+        glyph  (relevant in  vertical  glyph layouts  only).  This  is
+        useful to perform WYSIWYG text.
+
+        Note that  the two above field replace  the removed `metrics2'
+        field in the glyph slot.
+
+      advance:
+        This field is a vector  that gives the transformed advance for
+        the glyph.   By default, it corresponds to  the advance width,
+        unless  FT_LOAD_VERTICAL_LAYOUT  was  specified  when  calling
+        FT_Load_Glyph or FT_Load_Char.
+
+      bitmap_left:
+        This  field gives  the  distance in  integer  pixels from  the
+        current pen position  to the left-most pixel of  a glyph image
+        IF IT IS  A BITMAP.  It is only valid  when the `format' field
+        is set to `ft_glyph_format_bitmap', for example, after calling
+        the new function FT_Render_Glyph.
+
+      bitmap_top:
+        This  field gives  the  distance in  integer  pixels from  the
+        current pen position (located on the baseline) to the top-most
+        pixel of the  glyph image IF IT IS  A BITMAP.  Positive values
+        correspond to upwards Y.
+
+      loader:
+        This  is a  new  private  field for  the  glyph slot.   Client
+        applications should not touch it.
+
+
+    * Support for transforms and direct rendering in FT_Load_Glyph:
+
+      Most of the functionality found in <freetype/ftglyph.h> has been
+      moved to the core library.  Hence, the following:
+
+      - A   transform   can   be   specified  for   a   face   through
+        FT_Set_Transform.  this transform  is applied by FT_Load_Glyph
+        to  scalable glyph  images (i.e.  NOT TO  BITMAPS)  before the
+        function returns, unless the bit flag FT_LOAD_IGNORE_TRANSFORM
+        was set in the load flags.
+
+      - Once  a  glyph image  has  been  loaded,  it can  be  directly
+        converted  to  a  bitmap  by  using  the  new  FT_Render_Glyph
+        function.  Note that this  function takes the glyph image from
+        the glyph slot,  and converts it to a  bitmap whose properties
+        are returned  in `face.glyph.bitmap', `face.glyph.bitmap_left'
+        and `face.glyph.bitmap_top'.  The  original native image might
+        be lost after the conversion.
+
+      - When using the new  bit flag FT_LOAD_RENDER, the FT_Load_Glyph
+        and   FT_Load_Char   functions   will   call   FT_Render_Glyph
+        automatically when needed.
+
+  - Reformatted all  modules source  code in order  to get rid  of the
+    basic data types redefinitions (i.e. `TT_Int' instead of `FT_Int',
+    `T1_Fixed'  instead  of  `FT_Fixed').  Hence  the  format-specific
+    prefixes like  `TT_', `T1_',  `T2_' and `CID_'  are only  used for
+    relevant structures.
+

+
+OLD CHANGES FOR BETA 7
+
+  - bug-fixed the  OpenType/CFF parser.  It  now loads and displays my
+    two  fonts nicely,  but I'm  pretty certain  that more  testing is
+    needed :-)
+
+  - fixed the crummy Type 1 hinter, it now handles accented characters
+    correctly (well, the accent is  not always well placed, but that's
+    another problem..)
+
+  - added the CID-keyed Type 1 driver in `src/cid'.  Works pretty well
+    for only 13 Kb of code  ;-) Doesn't read AFM files though, nor the
+    really useful CMAP files..
+
+  - fixed  two  bugs  in  the  smooth  renderer  (src/base/ftgrays.c).
+    Thanks to Boris Letocha for spotting them and providing a fix.
+
+  - fixed potential `divide by zero' bugs in ftcalc.c.
+
+  - added source  code for  the OpenType/CFF driver  (still incomplete
+    though..)
+
+  - modified the  SFNT driver slightly  to perform more  robust header
+    checks  in TT_Load_SFNT_Header.  This prevents certain  font files
+    (e.g.  some  Type  1  Multiple  Masters)  from  being  incorrectly
+    `recognized' as TrueType font files..
+
+  - moved a lot of stuff from  the TrueType driver to the SFNT module,
+    this   allows   greater   code   re-use   between   font   drivers
+    (e.g. TrueType, OpenType, Compact-TrueType, etc..)
+
+  - added a tiny segment cache to the SFNT Charmap 4 decoder, in order
+    to minimally speed it up..
+
+  - added  support for  Multiple Master  fonts in  `type1z'.  There is
+    also a new file named <freetype/ftmm.h> which defines functions to
+    manage them from client applications.
+
+    The new file `src/base/ftmm.c' is also optional to the engine..
+
+  - various  formatting changes (e.g.  EXPORT_DEF ->  FT_EXPORT_DEF) +
+    small bug fixes in FT_Load_Glyph, the `type1' driver, etc..
+
+  - a minor fix to the Type 1 driver to let them apply the font matrix
+    correctly (used for many oblique fonts..)
+
+  - some fixes for 64-bit systems (mainly changing some FT_TRACE calls
+    to use %p instead of %lx).  Thanks to Karl Robillard.
+
+  - fixed  some bugs  in  the sbit  loader (src/base/sfnt/ttsbit.c)  +
+    added  a new flag,  FT_LOAD_CROP_BITMAP to  query that  bitmaps be
+    cropped when  loaded from a file  (maybe I should  move the bitmap
+    cropper to the base layer ??).
+
+  - changed the default  number of gray levels of  the smooth renderer
+    to 256  (instead of  the previous 128).  Of course, the  human eye
+    can't see any difference ;-)
+
+  - removed TT_MAX_SUBGLYPHS,  there is no static limit  on the number
+    of subglyphs in a TrueType font now..
+
+
+======================================================================
+
+OLD CHANGES 16 May 2000
+
+  - tagged `BETA-6'  in the  CVS tree.  This one is a  serious release
+    candidate even though it doesn't incorporate the auto-hinter yet..
+
+  - various obsolete files were removed, and copyright header updated
+
+  - finally  updated  the  standard   raster  to  fix  the  monochrome
+    rendering bug + re-enable  support for 5-gray levels anti-aliasing
+    (suck, suck..)
+
+  - created new header files, and modified sources accordingly:
+
+     <freetype/fttypes.h>
+       - simple FreeType types, without the API
+     <freetype/internal/ftmemory.h>
+       - definition of memory-management macros
+
+  - added   the   `DSIG'   (OpenType   Digital   Signature)   tag   to
+    <freetype/tttags.h>
+
+  - light update/cleaning of the build system + changes to the sources
+    in  order  to  get  rid  of _all_  compiler  warnings  with  three
+    compilers, i.e:
+
+    gcc with `-ansi -pedantic -Wall -W', Visual C++ with `/W3 /WX' and
+    LCC
+
+    IMPORTANT NOTE FOR WIN32-LCC USERS:
+    |
+    |  It seems the C pre-processor  that comes with LCC is broken, it
+    |  doesn't  recognize  the  ANSI  standard  directives  #  and  ##
+    |  correctly   when  one  of   the  argument  is  a  macro.  Also,
+    |  something like:
+    |
+    |     #define F(x)  print##x
+    |
+    |     F(("hello"))
+    |
+    |  will get incorrectly translated to:
+    |
+    |     print "hello")
+    |
+    |  by its pre-processor.  For this reason, you simply cannot build
+    |  FreeType 2 in debug mode with this compiler..
+
+  - yet  another massive grunt work.  I've  changed the  definition of
+    the EXPORT_DEF,  EXPORT_FUNC, BASE_DEF &  BASE_FUNC macros.  These
+    now take an argument, which is the function's return value type.
+
+    This  is necessary to  compile FreeType  as a  DLL on  Windows and
+    OS/2.  Depending on the compiler used, a compiler-specific keyword
+    like  __export or __system  must be  placed before  (VisualC++) or
+    after (BorlandC++) the type..
+
+    Of course, this needed a lot of changes throughout the source code
+    to make it compile again...  All cleaned up now, apparently..
+
+    Note also  that there is a  new EXPORT_VAR macro  defined to allow
+    the   _declaration_    of   an   exportable    public   (constant)
+    variable.  This  is  the   case  of  the  raster  interfaces  (see
+    ftraster.h and ftgrays.h), as well as each module's interface (see
+    sfdriver.h, psdriver.h, etc..)
+
+  - new feature: it  is now possible to pass  extra parameters to font
+                 drivers  when creating  a new  face object.  For now,
+                 this capability is unused.  It could however prove to
+                 be useful in a near future..
+
+      the FT_Open_Args structure was  changes, as well as the internal
+      driver interface  (the specific `init_face'  module function has
+      now a different signature).
+
+  - updated the tutorial (not finished though).
+
+  - updated the top-level BUILD  document
+
+  - fixed  a  potential memory  leak  that  could  occur when  loading
+    embedded bitmaps.
+
+  - added     the     declaration     of     FT_New_Memory_Face     in
+    <freetype/freetype.h>, as  it was  missing from the  public header
+    (the implementation was already in `ftobjs.c').
+
+  - the file <freetype/fterrors.h> has been seriously updated in order
+    to allow  the automatic generation  of error message tables.   See
+    the comments within it for more information.
+
+  - major directory  hierarchy re-organisation.  This was done for two
+    things:
+
+      * first,  to ease  the `manual'  compilation of  the  library by
+        requiring at lot less include paths :-)
+
+      * second,  to  allow  external  programs to  effectively  access
+        internal  data  fields.  For example,  this  can be  extremely
+        useful if  someone wants  to write a  font producer or  a font
+        manager on top of FreeType.
+
+    Basically, you  should now use  the 'freetype/' prefix  for header
+    inclusion, as in:
+
+        #include <freetype/freetype.h>
+        #include <freetype/ftglyph.h>
+
+    Some new include sub-directories are available:
+
+     a. the  `freetype/config' directory,  contains two files  used to
+        configure  the  build  of  the  library.  Client  applications
+        should  not need  to look  at these  normally, but they can if
+        they want.
+
+        #include <freetype/config/ftoption.h>
+        #include <freetype/config/ftconfig.h>
+
+     b. the `freetype/internal'  directory, contains header files that
+        describes library  internals.  These are the header files that
+        were  previously  found  in  the `src/base'  and  `src/shared'
+        directories.
+
+
+    As  usual, the build  system and  the demos  have been  updated to
+    reflect the change..
+
+    Here's a layout of the new directory hierarchy:
+
+    TOP_DIR
+      include/
+         freetype/
+            freetype.h
+            ...
+            config/
+              ftoption.h
+              ftconfig.h
+              ftmodule.h
+
+            internal/
+              ftobjs.h
+              ftstream.h
+              ftcalc.h
+              ...
+
+      src/
+         base/
+            ...
+
+         sfnt/
+         psnames/
+         truetype/
+         type1/
+         type1z/
+
+
+    Compiling a module is now  much easier, for example, the following
+    should work when in the TOP_DIR directory on an ANSI build:
+
+       gcc -c -I./include -I./src/base src/base/ftbase.c
+       gcc -c -I./include -I./src/sfnt src/sfnt/sfnt.c
+       etc..
+
+    (of course, using -Iconfig/<system> if you provide system-specific
+     configuration files).
+
+  - updated the structure of FT_Outline_Funcs in order to allow direct
+    coordinate scaling within  the outline decomposition routine (this
+    is  important for virtual  `on' points  with TrueType  outlines) +
+    updates to the rasters to support this..
+
+  - updated  the OS/2  table  loading code  in `src/sfnt/ttload.c'  in
+    order to support version 2 of the table (see OpenType 1.2 spec)
+
+  - created  `include/tttables.h'  and  `include/t1tables.h' to  allow
+    client applications to access some of  the SFNT and T1 tables of a
+    face  with  a  procedural  interface (see  `FT_Get_Sfnt_Table')  +
+    updates to internal source files to reflect the change..
+
+  - some  cleanups in  the source  code to  get rid  of  warnings when
+    compiling with the `-Wall -W -ansi -pedantic' options in gcc.
+
+  - debugged and moved the smooth renderer to `src/base/ftgrays.c' and
+    its header to `include/ftgrays.h'
+
+  - updated TT_MAX_SUBGLYPHS  to 96 as some CJK  fonts have composites
+    with up to 80 sub-glyphs !! Thanks to Werner
+
+
+======================================================================
+
+OLD CHANGES - 14-apr-2000
+
+  - fixed  a bug  in  the  TrueType glyph  loader  that prevented  the
+    correct loading of some CJK glyphs in mingli.ttf
+
+  - improved the standard Type 1 hinter in `src/type1'
+
+  - fixed two bugs  in the experimental Type 1  driver in `src/type1z'
+    to handle the new XFree86 4.0 fonts (and a few other ones..)
+
+  - the smooth  renderer is now  complete and supports  sub-banding to
+    render large glyphs  at high speed.  However, it is still  located
+    in `demos/src/ftgrays.c' and should move to the  library itself in
+    the next  beta.  NOTE: The  smooth  renderer  doesn't  compile  in
+    stand-alone mode anymore, but this should be fixed RSN..
+
+  - introduced convenience  functions to  more easily deal  with glyph
+    images, see  `include/ftglyph.h' for more details, as  well as the
+    new  demo program  named `demos/src/ftstring.c'  that demonstrates
+    its use
+
+  - implemented  FT_LOAD_NO_RECURSE in  both the  TrueType and  Type 1
+    drivers  (this  is required  by  the  auto-hinter  to improve  its
+    results).
+
+  - changed   the  raster   interface,  in   order  to   allow  client
+    applications  to   provide  their   own  span-drawing   callbacks.
+    However,   only   the   smooth   renderer   supports   this.   See
+    `FT_Raster_Params' in the file `include/ftimage.h'.
+
+  - fixed  a small bug  in FT_MulFix  that caused  incorrect transform
+    computation!
+
+  - Note: The tutorial is out-of-date.
+
+
+======================================================================
+
+OLD CHANGES - 12-mar-2000
+
+  - changed  the  layout  of  configuration  files  :  now,  all  ANSI
+    configuration         files         are         located         in
+    `freetype2/config'.  System-specific over-rides  can be  placed in
+    `freetype2/config/<system>'.
+
+  - moved all configuration macros to `config/ftoption.h'
+
+  - improvements in the Type 1 driver with AFM support
+
+  - changed the fields  in the FT_Outline structure :  the old `flags'
+    array is re-named `tags', while all ancient flags are encoded into
+    a single unsigned int named `flags'.
+
+  - introduced     new      flags     in     FT_Outline.flags     (see
+    ft_outline_.... enums in `ftimage.h').
+
+  - changed outline functions to `FT_Outline_<action>' syntax
+
+  - added a smooth anti-alias renderer to the demonstration programs
+
+  - added Mac graphics driver (thanks Just)
+
+  - FT_Open_Face  changed  in  order   to  received  a  pointer  to  a
+    FT_Open_Args descriptor..
+
+  - various  cleanups,  a  few  more API  functions  implemented  (see
+    FT_Attach_File)
+
+  - updated some docs
+
+
+======================================================================
+
+OLD CHANGES - 22-feb-2000
+
+  - introduced the `psnames' module.  It is used to:
+
+      o convert  a Postscript glyph  name into the  equivalent Unicode
+        character code (used by the  Type 1 driver(s) to synthesize on
+        the fly a Unicode charmap).
+
+      o provide an  interface to retrieve the Postscript  names of the
+        Macintosh,  Adobe  Standard &  Adobe  Expert character  codes.
+        (the Macintosh  names are  used by the  SFNT-module postscript
+        names support routines, while the other two tables are used by
+        the Type 1 driver(s)).
+
+  - introduced the `type1z' alternate Type 1 driver.  This is a (still
+    experimental) driver  for the Type  1 format that  will ultimately
+    replace the one  in `src/type1'.  It uses pattern matching to load
+    data from the font, instead of a finite  state analyzer.  It works
+    much better than the `old' driver with `broken' fonts.  It is also
+    much smaller (under 15 Kb).
+
+  - the  Type 1  drivers (both  in `src/type1'  and  `src/type1z') are
+    nearly  complete.  They  both  provide automatic  Unicode  charmap
+    synthesis through  the `psnames' module.  No re-encoding vector is
+    needed.  (note  that they  still  leak  memory  due to  some  code
+    missing, and I'm getting lazy).
+
+    Trivial AFM support has been added to read kerning information but
+    wasn't exactly tested as it should ;-)
+
+  - The TrueType  glyph loader has  been seriously rewritten  (see the
+    file  `src/truetype/ttgload.c'.  It is now  much, much  simpler as
+    well as  easier to read,  maintain and understand  :-) Preliminary
+    versions introduced a  memory leak that has been  reported by Jack
+    Davis, and is now fixed..
+
+  - introduced  the new  `ft_glyph_format_plotter', used  to represent
+    stroked outlines  like Windows `Vector' fonts, and  certain Type 1
+    fonts  like `Hershey'.  The corresponding  raster will  be written
+    soon.
+
+  - FT_New_Memory_Face  is  gone.  Likewise,  FT_Open_Face has  a  new
+    interface that uses a structure  to describe the input stream, the
+    driver (if required), etc..
+
+
+TODO
+
+  - Write FT_Get_Glyph_Bitmap and FT_Load_Glyph_Bitmap
+
+  - Add a function like FT_Load_Character(face, char_code, load_flags)
+    that  would   really  embed  a  call   to  FT_Get_Char_Index  then
+    FT_Load_Glyph to ease developer's work.
+
+  - Update the tutorial!
+
+  - consider adding  support for Multiple  Master fonts in the  Type 1
+    drivers.
+
+  - Test the AFM routines of the  Type 1 drivers to check that kerning
+    information is returned correctly.
+
+  - write a decent auto-gridding component  !! We need this to release
+    FreeType 2.0 gold !
+
+
+less urgent needs:
+
+  - add a CFF/Type2 driver
+  - add a BDF driver
+  - add a FNT/PCF/HBF driver
+  - add a Speedo driver from the X11 sources
+
+
+======================================================================
+
+OLDER CHANGES - 27-jan-2000
+
+  - updated the  `sfnt' module  interface to allow  several SFNT-based
+    drivers to co-exist peacefully
+
+  - updated  the `T1_Face'  type  to better  separate Postscript  font
+    content  from the  rest of  the FT_Face  structure.  Might be used
+    later by the CFF/Type2 driver..
+
+  - added an experimental replacement Type 1 driver featuring advanced
+    (and speedy) pattern matching to retrieve the data from postscript
+    fonts.
+
+  - very minor  changes in the implementation  of FT_Set_Char_Size and
+    FT_Set_Pixel_Sizes (they now implement default to lighten the font
+    driver's code).
+
+
+======================================================================
+
+OLD MESSAGE
+
+This file summarizes the changes  that occurred  since the last `beta'
+of FreeType 2. Because the list is important, it has been divided into
+separate sections:
+
+Table Of Contents:
+
+    I   High-Level Interface (easier !)
+   II   Directory Structure
+  III   Glyph Image Formats
+   IV   Build System
+    V   Portability
+   VI   Font Drivers
+
+
+----------------------------------------------------------------------
+
+High-Level Interface:
+
+  The high-level API has been considerably simplified.  Here is how:
+
+    - resource objects have disappeared.  this means that face objects
+      can now be created with  a single function call (see FT_New_Face
+      and FT_Open_Face)
+
+    - when calling  either FT_New_Face  & FT_Open_Face, a  size object
+      and a glyph slot object  are automatically created for the face,
+      and can  be accessed  through `face->glyph' and  `face->size' if
+      one really  needs to.   In most cases,  there's no need  to call
+      FT_New_Size or FT_New_Glyph.
+
+    - similarly,  FT_Load_Glyph  now  only  takes  a  `face'  argument
+      (instead  of a  glyph  slot  and a  size).  Also,  its  `result'
+      parameter is  gone, as the glyph  image type is  returned in the
+      field `face->glyph.format'
+
+    - the list  of available  charmaps is directly  accessible through
+      `face->charmaps', counting `face->num_charmaps'  elements.  Each
+      charmap  has an  'encoding'  field which  specifies which  known
+      encoding it deals with.  Valid values are, for example:
+
+          ft_encoding_unicode      (for ASCII, Latin-1 and Unicode)
+          ft_encoding_apple_roman
+          ft_encoding_sjis
+          ft_encoding_adobe_standard
+          ft_encoding_adobe_expert
+
+      other  values may  be added  in the  future.  Each charmap still
+      holds  its `platform_id'  and `encoding_id'  values in  case the
+      encoding is too exotic for the current library
+
+
+----------------------------------------------------------------------
+
+Directory Structure:
+
+  Should seem obvious to most of you:
+
+     freetype/
+         config/        -- configuration sub-makefiles
+            ansi/
+            unix/       -- platform-specific configuration files
+            win32/
+            os2/
+            msdos/
+
+         include/       -- public header  files, those to  be included
+                           directly by client apps
+
+         src/           -- sources of the library
+           base/        -- the base layer
+           sfnt/        -- the sfnt `driver'  (see the drivers section
+                           below)
+           truetype/    -- the truetype driver
+           type1/       -- the type1 driver
+           shared/      -- some header files shared between drivers
+
+         demos/         -- demos/tools
+
+         docs/          -- documentation (a bit empty for now)
+
+
+----------------------------------------------------------------------
+
+Glyph Image Formats:
+
+  Drivers are now able to  register new glyph image formats within the
+  library.  For  now, the  base layer supports  of course  bitmaps and
+  vector  outlines, but  one  could imagine  something different  like
+  colored bitmaps, bi-color vectors or whatever else (Metafonts anyone
+  ??).
+
+  See  the   file  `include/ftimage.h'.   Note  also  that   the  type
+  FT_Raster_Map  is gone,  and  is now  replaced  by FT_Bitmap,  which
+  should encompass all known bitmap types.
+
+  Each new  image format  must provide at  least one `raster',  i.e. a
+  module capable of  transforming the glyph image into a bitmap.  It's
+  also possible  to change the default  raster used for  a given glyph
+  image format.
+
+  The default outline  scan-converter now uses 128 levels  of grays by
+  default,  which tends  to smooth  many  things.  Note that the  demo
+  programs have been updated significantly in order to display these..
+
+
+----------------------------------------------------------------------
+
+Build system:
+
+  You still need  GNU Make to build the library.  The build system has
+  been very seriously re-vamped in order to provide things like :
+
+   - automatic host platform  detection (reverting to 'config/ansi' if
+     it is not detected, with pseudo-standard compilation flags)
+
+   - the ability to compile from the Makefiles with very different and
+     exotic compilers.  Note that linking the library can be difficult
+     for some platforms.
+
+     For example, the file `config/win32/lcclib.bat' is invoked by the
+     build system to create the `.lib' file with LCC-Win32 because its
+     librarian  has too  many flaws  to be  invoked directly  from the
+     Makefile.
+
+  Here's how it works:
+
+  - the first time you type `make',  the build system runs a series of
+    sub-makefiles  in order  to detect  your host  platform.  It  then
+    dumps what it found, and creates a file called `config.mk' in  the
+    current  directory.  This is a  sub-Makefile used  to  define many
+    important Make variables used to build the library.
+
+  - the second time, the build system detects the `config.mk' then use
+    it  to  build the  library.  All object  files  go  into 'obj'  by
+    default,  as well  as the  library file,  but this  can  easily be
+    changed.
+
+  Note that  you can run `make  setup' to force  another host platform
+  detection  even   if  a  `config.mk'  is  present   in  the  current
+  directory.  Another solution  is  simply to  delete  the file,  then
+  re-run make.
+
+  Finally, the  default compiler  for all platforms  is gcc  (for now,
+  this will hopefully changed in the future).  You can however specify
+  a different  compiler by specifying  it after the 'setup'  target as
+  in:
+
+      gnumake setup lcc         on Win32 to use the LCC compiler
+      gnumake setup visualc     on Win32 to use Visual C++
+
+  See  the file  `config/<system>/detect.mk' for  a list  of supported
+  compilers for your platforms.
+
+  It should be relatively easy  to write new detection rules files and
+  config.mk..
+
+  Finally, to  build the demo programs,  go to `demos'  and launch GNU
+  Make, it will use the `config.mk'  in the top directory to build the
+  test programs..
+
+
+----------------------------------------------------------------------
+
+Portability:
+
+  In  the  previous  beta,  a  single FT_System  object  was  used  to
+  encompass  all  low-level  operations like  thread  synchronisation,
+  memory management and i/o access.  This has been greatly simplified:
+
+    - thread synchronisation  has been dropped, for  the simple reason
+      that the library  is already re-entrant, and that  if you really
+      need  two  threads accessing  the  same  FT_Library, you  should
+      really synchronize access to it yourself with a simple mutex.
+
+    - memory  management is  performed  through a  very simple  object
+      called `FT_Memory',  which really is a table  containing a table
+      of pointers to  functions like malloc, realloc and  free as well
+      as some user data (closure).
+
+    - resources have disappeared (they created more problems than they
+      solved), and  i/o management have  been simplified greatly  as a
+      result.  Streams are  defined through  FT_Stream objects,  which
+      can be either memory-based or disk-based.
+
+      Note that  each face  has its own  stream, which is  closed only
+      when  the  face object  is  destroyed.  Hence,  a function  like
+      TT_Flush_Face in 1.x cannot be directly  supported.  However, if
+      you really need something like  this, you can easily tailor your
+      own streams  to achieve the same  feature at a  lower level (and
+      use FT_Open_Face instead of FT_New_Face to create the face).
+
+  See the file  `include/ftsystem.h' for more details, as  well as the
+  implementations found in `config/unix' and `config/ansi'.
+
+
+----------------------------------------------------------------------
+
+Font Drivers:
+
+  The  Font Driver  interface has  been modified  in order  to support
+  extensions & versioning.
+
+
+  The  list of  the font  drivers that  are statically  linked  to the
+  library at compile time is  managed through a new configuration file
+  called `config/<platform>/ftmodule.h'.
+
+  This  file is  autogenerated  when  invoking  `make modules'.   This
+  target  will  parse  all  sub-directories  of  'src', looking  for a
+  `module.mk' rules  file, used  to describe  the driver to  the build
+  system.
+
+  Hence, one  should call  `make modules' each  time a font  driver is
+  added or removed from the `src' directory.
+
+  Finally, this  version  provides  a `pseudo-driver'  in  `src/sfnt'.
+  This  driver  doesn't  support  font  files  directly, but  provides
+  services used by all TrueType-like font drivers.  Hence, its code is
+  shared between  the TrueType & OpenType  font formats,  and possibly
+  more formats to come if we're lucky..
+
+
+----------------------------------------------------------------------
+
+Extensions support:
+
+  The extensions support is inspired by the one found in 1.x.
+
+  Now, each font driver has  its own `extension registry', which lists
+  which extensions  are available  for the font  faces managed  by the
+  driver.
+
+  Extension ids are  now strings, rather than 4-byte  tags, as this is
+  usually more readable.
+
+  Each extension has:
+    - some data, associated to each face object
+    - an interface (table of function pointers)
+
+  An extension  that is format-specific should  simply register itself
+  to the correct font driver.  Here is some example code:
+
+   // Registering an extensions
+   //
+   FT_Error  FT_Init_XXXX_Extension( FT_Library  library )
+   {
+     FT_DriverInterface*  tt_driver;
+
+     driver = FT_Get_Driver( library, "truetype" );
+     if (!driver) return FT_Err_Unimplemented_Feature;
+
+     return FT_Register_Extension( driver, &extension_class );
+   }
+
+
+   // Implementing the extensions
+   //
+   FT_Error  FT_Proceed_Extension_XXX( FT_Face  face )
+   {
+     FT_XXX_Extension            ext;
+     FT_XXX_Extension_Interface  ext_interface;
+
+     ext = FT_Get_Extension( face, "extensionid", &ext_interface );
+     if (!ext) return error;
+
+     return ext_interface->do_it(ext);
+   }
+

+How to customize the compilation of the library
+===============================================
+
+  FreeType  is highly  customizable  to fit  various  needs, and  this
+  document  describes  how  it  is  possible  to  select  options  and
+  components at compilation time.
+
+
+I. Configuration macros
+
+  The  file `include/freetype/config/ftoption.h'  contains a  list  of
+  commented configuration macros that can  be toggled by developers to
+  indicate which features should be active while building the library.
+
+  These  options range  from debug  level to  availability  of certain
+  features,   like  native   TrueType  hinting   through   a  bytecode
+  interpreter.
+
+  We  invite you  to read  this file  for more  information.   You can
+  change the  file's content to suit  your needs, or  override it with
+  one of the techniques described below.
+
+
+II. Modules list
+
+  If you  use GNU make  please edit the top-level  file `modules.cfg'.
+  It contains a  list of available FreeType modules  and extensions to
+  be compiled.  Change it to suit your own preferences.  Be aware that
+  certain modules  depend on  others, as described  in the  file.  GNU
+  make  uses `modules.cfg'  to  generate `ftmodule.h'  (in the  object
+  directory).
+
+  If you build FreeType in a directory separate from the source files,
+  put your  customized `modules.cfg' in  that directory; that  way you
+  can keep the source files `clean'.
+
+  If  you don't  use  GNU make  you  have to  manually  edit the  file
+  `include/freetype/config/ftmodule.h' (which  is *not* used  with  if
+  compiled with GNU make) to add  or remove the drivers and components
+  you want  to compile into  the library.  See `INSTALL.ANY'  for more
+  information.
+
+
+III. System interface
+
+  FreeType's  default interface to  the system  (i.e., the  parts that
+  deal  with  memory  management   and  i/o  streams)  is  located  in
+  `src/base/ftsystem.c'.
+
+  The current  implementation uses standard C library  calls to manage
+  memory  and to read  font files.   It is  however possible  to write
+  custom implementations to suit specific systems.
+
+  To  tell the  GNU Make-based  build system  to use  a  custom system
+  interface, you have to  define the environment variable FTSYS_SRC to
+  point to the relevant implementation:
+
+    on Unix:
+
+      ./configure <your options>
+      export FTSYS_SRC=foo/my_ftsystem.c
+      make
+      make install
+
+    on Windows:
+
+      make setup <compiler>
+      set FTSYS_SRC=foo/my_ftsystem.c
+      make
+
+
+IV. Overriding default configuration and module headers
+
+  It  is possible  to override  the default  configuration  and module
+  headers without  changing the original files.  There  are three ways
+  to do that:
+
+
+  1. With GNU make
+
+    [This is actually a combination of method 2 and 3.]
+
+    Just put your custom `ftoption.h'  file into the objects directory
+    (normally `<topdir>/objs' if you build  in the source tree, or the
+    directory where  you invoke configure  if you build in  a separate
+    directory), which GNU make prefers over the standard location.  No
+    action  is  needed  for   `ftmodule.h'  because  it  is  generated
+    automatically in the objects directory.
+
+  2. Using the C include path
+
+    Use the  C include path  to ensure that  your own versions  of the
+    files are used at compile time when the lines
+
+      #include FT_CONFIG_OPTIONS_H
+      #include FT_CONFIG_MODULES_H
+
+    are      compiled.       Their      default      values      being
+    <freetype/config/ftoption.h> and <freetype/config/ftmodule.h>, you
+    can do something like:
+
+      custom/
+        config/
+          ftoption.h      => custom options header
+          ftmodule.h      => custom modules list
+
+      include/            => normal FreeType 2 include
+        ...
+
+    then change the C include path to always give the path to `custom'
+    before the FreeType 2 `include'.
+
+
+  3. Redefining FT_CONFIG_OPTIONS_H and FT_CONFIG_MODULES_H
+
+    Another way to do the same thing is to redefine the macros used to
+    name  the configuration  headers.  To  do  so, you  need a  custom
+    `ft2build.h' whose content can be as simple as:
+
+      #ifndef FT2_BUILD_MY_PLATFORM_H_
+      #define FT2_BUILD_MY_PLATFORM_H_
+
+      #define FT_CONFIG_OPTIONS_H  <custom/my-ftoption.h>
+      #define FT_CONFIG_MODULES_H  <custom/my-ftmodule.h>
+
+      #include <freetype/config/ftheader.h>
+
+      #endif /* FT2_BUILD_MY_PLATFORM_H_ */
+
+    Place those files in a separate directory, e.g.,
+
+      custom/
+        ft2build.h           => custom version described above
+        my-ftoption.h        => custom options header
+        my-ftmodule.h        => custom modules list header
+
+    and change  the C include path  to ensure that  `custom' is always
+    placed before the FT2 `include' during compilation.
+

+Debugging within the FreeType sources
+=====================================
+
+I. Configuration macros
+-----------------------
+
+There are  several ways to enable  debugging features in a  FreeType 2
+builds.  This is  controlled through the definition  of special macros
+located in the file `ftoption.h'.  The macros are:
+
+
+  FT_DEBUG_LEVEL_ERROR
+
+    #define this macro if you want to compile the FT_ERROR macro calls
+    to print error  messages during program execution.   This will not
+    stop  the  program.  Very  useful  to  spot invalid  fonts  during
+    development and to code workarounds for them.
+
+  FT_DEBUG_LEVEL_TRACE
+
+    #define this macro if you want to compile both macros FT_ERROR and
+    FT_TRACE.  This  also includes the variants  FT_TRACE0, FT_TRACE1,
+    FT_TRACE2, ..., FT_TRACE7.
+
+    The  trace macros  are used  to  send debugging  messages when  an
+    appropriate  `debug level'  is configured  at runtime  through the
+    FT2_DEBUG environment variable (more on this later).
+
+  FT_DEBUG_MEMORY
+
+    If this  macro is #defined, the  FreeType engine is linked  with a
+    small  but  effective debugging  memory  manager  that tracks  all
+    allocations and frees that are performed within the font engine.
+
+    When  the  FT2_DEBUG_MEMORY  environment variable  is  defined  at
+    runtime, a  call to FT_Done_FreeType will  dump memory statistics,
+    including  the  list  of  leaked memory  blocks  with  the  source
+    locations where  these were allocated.   It is always a  very good
+    idea to define this in  development builds.  This works with _any_
+    program linked to FreeType, but requires a big deal of memory (the
+    debugging memory  manager never  frees the blocks  to the  heap in
+    order to detect double frees).
+
+    When  FT2_DEBUG_MEMORY isn't  defined  at  runtime, the  debugging
+    memory manager is ignored, and performance is unaffected.
+
+
+II. Debugging macros
+--------------------
+
+Several  macros  can be  used  within  the  FreeType sources  to  help
+debugging its code:
+
+
+  1. FT_ERROR(( ... ))
+
+    This macro is used to send debug messages that indicate relatively
+    serious errors  (like broken  font files), but  will not  stop the
+    execution of the running program.   Its code is compiled only when
+    either FT_DEBUG_LEVEL_ERROR or FT_DEBUG_LEVEL_TRACE are defined in
+    `ftoption.h'.
+
+    Note that you have to use a printf-like signature, but with double
+    parentheses, like in
+
+      FT_ERROR(( "your %s is not %s\n", "foo", "bar" ));
+
+
+  2. FT_ASSERT( condition )
+
+    This macro is used to check  strong assertions at runtime.  If its
+    condition isn't TRUE, the program will abort with a panic message.
+    Its  code   is  compiled   when  either   FT_DEBUG_LEVEL_ERROR  or
+    FT_DEBUG_LEVEL_TRACE   are  defined.    You   don't  need   double
+    parentheses here.  For example
+
+      FT_ASSERT( ptr != NULL );
+
+
+  3. FT_TRACE( level, (message...) )
+
+    The  FT_TRACE  macro is  used  to  send general-purpose  debugging
+    messages during program execution.   This macro uses an *implicit*
+    macro  named  FT_COMPONENT  used  to  name  the  current  FreeType
+    component being run.
+
+    The developer  should always  define FT_COMPONENT  as appropriate,
+    for example as in
+
+      #undef  FT_COMPONENT
+      #define FT_COMPONENT  trace_io
+
+    The  value  of the  FT_COMPONENT  macro  is an  enumeration  named
+    `trace_XXXX' where `XXXX' is one of the component names defined in
+    the internal  file `internal/fttrace.h'.   If you  modify FreeType
+    source and insert new `trace_XXXX'  macro, you must register it in
+    `fttrace.h'. If  you insert or  remove many trace macros,  you can
+    check   the    undefined   or   the   unused    trace   macro   by
+    `src/tools/chktrcmp.py'.
+
+    Each such component is assigned a `debug level', ranging from 0 to
+    7,  through   the  use  of  the   FT2_DEBUG  environment  variable
+    (described below) when a program linked with FreeType starts.
+
+    When FT_TRACE is  called, its level is compared to  the one of the
+    corresponding component.  Messages with trace levels *higher* than
+    the corresponding component level are filtered and never printed.
+
+    This means  that trace messages  with level 0 are  always printed,
+    those with  level 2 are only  printed when the component  level is
+    *at least* 2.
+
+    The  second parameter  to  FT_TRACE must  contain parentheses  and
+    correspond to a printf-like call, as in
+
+      FT_TRACE( 2, ( "your %s is not %s\n", "foo", "bar" ) )
+
+    The   shortcut  macros   FT_TRACE0,  FT_TRACE1,   FT_TRACE2,  ...,
+    FT_TRACE7 can  be used with  constant level indices, and  are much
+    cleaner to use, as in
+
+      FT_TRACE2(( "your %s is not %s\n", "foo", "bar" ));
+
+
+III. Environment variables
+--------------------------
+
+The  following  environment  variables control  debugging  output  and
+behaviour of FreeType at runtime.
+
+
+  FT2_DEBUG
+
+    This  variable   is  only  used   when  FreeType  is   built  with
+    FT_DEBUG_LEVEL_TRACE  defined.  It  contains a  list of  component
+    level definitions, following this format:
+
+      component1:level1 component2:level2 component3:level3 ...
+
+    where `componentX' is the name  of a tracing component, as defined
+    in `fttrace.h', but without the  `trace_' prefix.  `levelX' is the
+    corresponding level to use at runtime.
+
+    `any'  is a  special component  name that  will be  interpreted as
+    `any/all components'.  For example, the following definitions
+
+      set FT2_DEBUG=any:2 memory:5 io:4        (on Windows)
+      export FT2_DEBUG="any:2 memory:5 io:4"   (on Linux with bash)
+
+    both stipulate that all components should have level 2, except for
+    the memory and  io components which will be set  to trace levels 5
+    and 4, respectively.
+
+
+  FT2_DEBUG_MEMORY
+
+    This environment variable,  when defined, tells FreeType  to use a
+    debugging memory manager that will  track leaking memory blocks as
+    well as other common errors like double frees.  It is also capable
+    of  reporting _where_  the  leaking blocks  were allocated,  which
+    considerably  saves  time  when  debugging new  additions  to  the
+    library.
+
+    This  code  is only  compiled  when  FreeType  is built  with  the
+    FT_DEBUG_MEMORY macro #defined in  `ftoption.h' though, it will be
+    ignored in other builds.
+
+
+  FT2_ALLOC_TOTAL_MAX
+
+    This variable is  ignored if FT2_DEBUG_MEMORY is  not defined.  It
+    allows  you  to  specify  a  maximum  heap  size  for  all  memory
+    allocations performed  by FreeType.  This  is very useful  to test
+    the robustness  of the  font engine  and programs  that use  it in
+    tight memory conditions.
+
+    If it is undefined, or if its value is not strictly positive, then
+    no allocation bounds are checked at runtime.
+
+
+  FT2_ALLOC_COUNT_MAX
+
+    This variable is  ignored if FT2_DEBUG_MEMORY is  not defined.  It
+    allows  you to  specify  a maximum  number  of memory  allocations
+    performed    by    FreeType    before    returning    the    error
+    FT_Err_Out_Of_Memory.  This  is useful  for debugging  and testing
+    the engine's robustness.
+
+    If it is undefined, or if its value is not strictly positive, then
+    no allocation bounds are checked at runtime.

+Introduction
+============
+
+  The FreeType  Project is distributed in  several archive packages;
+  some of them may contain, in addition to the FreeType font engine,
+  various tools and  contributions which rely on, or  relate to, the
+  FreeType Project.
+
+  This  license applies  to all  files found  in such  packages, and
+  which do not  fall under their own explicit  license.  The license
+  affects  thus  the  FreeType   font  engine,  the  test  programs,
+  documentation and makefiles, at the very least.
+
+  This  license   was  inspired  by  the  BSD,   Artistic,  and  IJG
+  (Independent JPEG  Group) licenses, which  all encourage inclusion
+  and  use of  free  software in  commercial  and freeware  products
+  alike.  As a consequence, its main points are that:
+
+    o We don't promise that this software works. However, we will be
+      interested in any kind of bug reports. (`as is' distribution)
+
+    o You can  use this software for whatever you  want, in parts or
+      full form, without having to pay us. (`royalty-free' usage)
+
+    o You may not pretend that  you wrote this software.  If you use
+      it, or  only parts of it,  in a program,  you must acknowledge
+      somewhere  in  your  documentation  that  you  have  used  the
+      FreeType code. (`credits')
+
+  We  specifically  permit  and  encourage  the  inclusion  of  this
+  software, with  or without modifications,  in commercial products.
+  We  disclaim  all warranties  covering  The  FreeType Project  and
+  assume no liability related to The FreeType Project.
+
+
+  Finally,  many  people  asked  us  for  a  preferred  form  for  a
+  credit/disclaimer to use in compliance with this license.  We thus
+  encourage you to use the following text:
+
+   """
+    Portions of this software are copyright © <year> The FreeType
+    Project (www.freetype.org).  All rights reserved.
+   """
+
+  Please replace <year> with the value from the FreeType version you
+  actually use.
+
+
+Legal Terms
+===========
+
+0. Definitions
+--------------
+
+  Throughout this license,  the terms `package', `FreeType Project',
+  and  `FreeType  archive' refer  to  the  set  of files  originally
+  distributed  by the  authors  (David Turner,  Robert Wilhelm,  and
+  Werner Lemberg) as the `FreeType Project', be they named as alpha,
+  beta or final release.
+
+  `You' refers to  the licensee, or person using  the project, where
+  `using' is a generic term including compiling the project's source
+  code as  well as linking it  to form a  `program' or `executable'.
+  This  program is  referred to  as  `a program  using the  FreeType
+  engine'.
+
+  This  license applies  to all  files distributed  in  the original
+  FreeType  Project,   including  all  source   code,  binaries  and
+  documentation,  unless  otherwise  stated   in  the  file  in  its
+  original, unmodified form as  distributed in the original archive.
+  If you are  unsure whether or not a particular  file is covered by
+  this license, you must contact us to verify this.
+
+  The FreeType  Project is copyright (C) 1996-2000  by David Turner,
+  Robert Wilhelm, and Werner Lemberg.  All rights reserved except as
+  specified below.
+
+1. No Warranty
+--------------
+
+  THE FREETYPE PROJECT  IS PROVIDED `AS IS' WITHOUT  WARRANTY OF ANY
+  KIND, EITHER  EXPRESS OR IMPLIED,  INCLUDING, BUT NOT  LIMITED TO,
+  WARRANTIES  OF  MERCHANTABILITY   AND  FITNESS  FOR  A  PARTICULAR
+  PURPOSE.  IN NO EVENT WILL ANY OF THE AUTHORS OR COPYRIGHT HOLDERS
+  BE LIABLE  FOR ANY DAMAGES CAUSED  BY THE USE OR  THE INABILITY TO
+  USE, OF THE FREETYPE PROJECT.
+
+2. Redistribution
+-----------------
+
+  This  license  grants  a  worldwide, royalty-free,  perpetual  and
+  irrevocable right  and license to use,  execute, perform, compile,
+  display,  copy,   create  derivative  works   of,  distribute  and
+  sublicense the  FreeType Project (in  both source and  object code
+  forms)  and  derivative works  thereof  for  any  purpose; and  to
+  authorize others  to exercise  some or all  of the  rights granted
+  herein, subject to the following conditions:
+
+    o Redistribution of  source code  must retain this  license file
+      (`FTL.TXT') unaltered; any  additions, deletions or changes to
+      the original  files must be clearly  indicated in accompanying
+      documentation.   The  copyright   notices  of  the  unaltered,
+      original  files must  be  preserved in  all  copies of  source
+      files.
+
+    o Redistribution in binary form must provide a  disclaimer  that
+      states  that  the software is based in part of the work of the
+      FreeType Team,  in  the  distribution  documentation.  We also
+      encourage you to put an URL to the FreeType web page  in  your
+      documentation, though this isn't mandatory.
+
+  These conditions  apply to any  software derived from or  based on
+  the FreeType Project,  not just the unmodified files.   If you use
+  our work, you  must acknowledge us.  However, no  fee need be paid
+  to us.
+
+3. Advertising
+--------------
+
+  Neither the  FreeType authors and  contributors nor you  shall use
+  the name of the  other for commercial, advertising, or promotional
+  purposes without specific prior written permission.
+
+  We suggest,  but do not require, that  you use one or  more of the
+  following phrases to refer  to this software in your documentation
+  or advertising  materials: `FreeType Project',  `FreeType Engine',
+  `FreeType library', or `FreeType Distribution'.
+
+  As  you have  not signed  this license,  you are  not  required to
+  accept  it.   However,  as  the FreeType  Project  is  copyrighted
+  material, only  this license, or  another one contracted  with the
+  authors, grants you  the right to use, distribute,  and modify it.
+  Therefore,  by  using,  distributing,  or modifying  the  FreeType
+  Project, you indicate that you understand and accept all the terms
+  of this license.
+
+4. Contacts

+		    GNU GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+     51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year  name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+
+There are  several ways  to build the  FreeType library,  depending on
+your system and the level of  customization you need.  Here is a short
+overview of the documentation available:
+
+
+I. Normal installation and upgrades
+===================================
+
+  1. Unix Systems (including Mac OS X, Cygwin, and MSys on Windows)
+
+    Please read `INSTALL.UNIX' to install or upgrade FreeType  2 on  a
+    Unix system.   Note  that  you  *need*  GNU  Make   for  automatic
+    compilation,  since other make tools won't work (this includes BSD
+    Make).
+
+    GNU Make VERSION 3.81 OR NEWER IS NEEDED!
+
+    [For `cmake' see below.]
+
+
+  2. On VMS with the `mms' build tool
+
+    See `INSTALL.VMS' for installation instructions on this platform.
+
+
+  3. Other systems using GNU Make
+
+    On non-Unix platforms,  it is possible to build  the library using
+    GNU Make  utility.  Note that  *NO OTHER MAKE TOOL  WILL WORK*[1]!
+    This  methods supports  several  compilers on  Windows, OS/2,  and
+    BeOS, including MinGW, Visual C++, Borland C++, and more.
+
+    Instructions are provided in the file `INSTALL.GNU'.
+
+
+  4. With an IDE Project File (e.g., for Visual Studio or CodeWarrior)
+
+    We provide a  small number of `project files'  for various IDEs to
+    automatically build  the library as  well.  Note that  these files
+    are  not supported  and only  sporadically maintained  by FreeType
+    developers, so don't expect them to work in each release.
+
+    To find them, have a  look at the content of the `builds/<system>'
+    directory, where <system> stands for your OS or environment.
+
+
+  5. Using cmake
+
+    See the top-level `CMakeLists.txt' file for more information.
+
+
+  6. From you own IDE, or own Makefiles
+
+    If  you  want  to  create   your  own  project  file,  follow  the
+    instructions   given  in  the   `INSTALL.ANY'  document   of  this
+    directory.
+
+
+II. Custom builds of the library
+================================
+
+  Customizing the compilation  of FreeType is easy, and  allows you to
+  select only the components of  the font engine that you really need.
+  For more details read the file `CUSTOMIZE'.
+
+
+----------------------------------------------------------------------
+
+[1] make++, a make tool written in Perl, has sufficient support of GNU
+    make extensions to build FreeType.  See
+
+      http://makepp.sourceforge.net
+
+    for more information;  you need version 2.0 or newer, and you must
+    pass option `--norc-substitution'.

+Instructions on how to build FreeType with your own build tool
+==============================================================
+
+See  the  file `CUSTOMIZE'  to  learn  how  to customize  FreeType  to
+specific environments.
+
+
+I. Standard procedure
+---------------------
+
+  * DISABLE PRE-COMPILED  HEADERS!  This is very  important for Visual
+    C++, because FreeType uses lines like:
+
+      #include FT_FREETYPE_H
+
+    which are not correctly supported by this compiler while being ISO
+    C compliant!
+
+  * You need to add the directory `include' to your  include path when
+    compiling the library.
+
+  * FreeType 2 is made of  several components; each of them is located
+    in    a   subdirectory    of   `freetype2/src'.     For   example,
+    `freetype2/src/truetype/' contains the TrueType font driver.
+
+  * DO NOT COMPILE ALL C FILES!  Rather, compile the following ones.
+
+    -- base components (required)
+
+      src/base/ftsystem.c
+      src/base/ftinit.c

+       formats)
+
+      src/raster/raster.c     -- monochrome rasterizer
+      src/smooth/smooth.c     -- anti-aliasing rasterizer
+
+    -- auxiliary modules (optional)
+
+      src/autofit/autofit.c   -- auto hinting module

+      src/lzw/ftlzw.c         -- support for compressed fonts (.Z)
+      src/bzip2/ftbzip2.c     -- support for compressed fonts (.bz2)
+      src/gxvalid/gxvalid.c   -- TrueTypeGX/AAT table validation
+      src/otvalid/otvalid.c   -- OpenType table validation
+      src/psaux/psaux.c       -- PostScript Type 1 parsing
+      src/pshinter/pshinter.c -- PS hinting module
+      src/psnames/psnames.c   -- PostScript glyph names support
+
+
+    Notes:
+
+      `ftcache.c'  needs `ftglyph.c'
+      `ftfstype.c' needs `fttype1.c'
+      `ftglyph.c'  needs `ftbitmap.c'
+      `ftstroke.c' needs `ftglyph.c'
+      `ftsynth.c'  needs `ftbitmap.c'
+
+      `cff.c'      needs `sfnt.c', `pshinter.c', and `psnames.c'
+      `truetype.c' needs `sfnt.c' and `psnames.c'
+      `type1.c'    needs `psaux.c' `pshinter.c', and `psnames.c'
+      `type1cid.c' needs `psaux.c', `pshinter.c', and `psnames.c'
+      `type42.c'   needs `truetype.c'
+
+      Please consult the central  `include/freetype/config/ftoption.h'
+      configuration file for details on additional libraries necessary
+      for some optional features.
+
+
+  Read the file `CUSTOMIZE' in case  you want to compile only a subset
+  of  the  drivers,  renderers,   and  optional  modules;  a  detailed
+  description of the various base  extension is given in the top-level
+  file `modules.cfg'.
+
+  You are done.  In case of problems, see the archives of the FreeType
+  development mailing list.
+
+
+II. Support for flat-directory compilation
+------------------------------------------
+
+  It is  possible to  put all  FreeType 2 source  files into  a single
+  directory, with the *exception* of the `include' hierarchy.
+
+  1. Copy all files in current directory
+
+      cp freetype2/src/base/*.[hc] .
+      cp freetype2/src/raster1/*.[hc] .
+      cp freetype2/src/smooth/*.[hc] .
+      etc.
+
+  2. Compile sources
+
+      cc -c -Iinclude -DFT2_BUILD_LIBRARY ftsystem.c
+      cc -c -Iinclude -DFT2_BUILD_LIBRARY ftinit.c
+      cc -c -Iinclude -DFT2_BUILD_LIBRARY ftdebug.c
+      cc -c -Iinclude -DFT2_BUILD_LIBRARY ftbase.c
+      etc.
+
+    You don't  need to define  the FT_FLAT_COMPILATION macro  (as this
+    was required in previous releases of FreeType 2).

+This document contains instructions on how to cross-build the FreeType
+library on Unix systems, for example, building binaries for Linux/MIPS
+on  FreeBSD/i386.  Before  reading this  document, please  consult the
+file  `INSTALL.UNIX' for  required tools  and the  basic self-building
+procedure.
+
+
+  1. Required Tools
+  -----------------
+
+    For self-building the FreeType library  on a Unix system, GNU Make
+    3.81 or newer  is required.  `INSTALL.UNIX' contains  hints how to
+    check the installed `make'.
+
+    The GNU C  compiler to cross-build the target  system is required.
+    Currently, using a non-GNU cross  compiler is untested.  The cross
+    compiler is  expected to be  installed with a system  prefix.  For
+    example, if  your building system  is FreeBSD/i386 and  the target
+    system is Linux/MIPS, the cross  compiler should be installed with
+    the name `mips-ip22-linuxelf-gcc'.
+
+    A C  compiler for a self-build  is required also, to  build a tool
+    (`apinames') that is executed during the build procedure.  Non-GNU
+    self compilers are acceptable, but such a setup is untested.
+
+
+  2. Configuration
+  ----------------
+
+    2.1. Building and target system
+
+      To configure  a cross-build,  the options  `--host=<system>' and
+      `--build=<system>'  must be  passed to  the `configure'  script.
+      For example, if your build system is FreeBSD/i386 and the target
+      system is Linux/MIPS, say
+
+        ./configure \
+          --build=i386-unknown-freebsd \
+          --host=mips-ip22-linuxelf \
+          [other options]
+
+      It should  be noted that `--host=<system>'  specifies the system
+      where the built binaries will  be executed, not the system where
+      the build actually happens.   Older versions of GNU autoconf use
+      the option  pair `--host=' and `--target='.  This  is broken and
+      doesn't work.  Similarly, an explicit CC specification like
+
+        env CC=mips-ip22-linux-gcc ./configure                 # BAD
+
+      or
+
+        env CC=/usr/local/mips-ip22-linux/bin/gcc ./configure  # BAD
+
+      doesn't   work  either;  such   a  configuration   confuses  the
+      `configure' script while  trying to find the cross  and native C
+      compilers.
+
+
+    2.2. The prefix to install FreeType2
+
+      Setting `--prefix=<prefix>'  properly is important.   The prefix
+      to  install  FreeType2  is written  into  the  `freetype-config'
+      script and `freetype2.pc' configuration file.
+
+      If  the built  FreeType  2 library  is  used as  a  part of  the
+      cross-building system,  the prefix  is expected to  be different
+      from  the self-building  system.  For  example, a  configuration
+      with   `--prefix=/usr/local'   installs    binaries   into   the
+      system-wide `/usr/local' directory, which then can't be executed
+      due  to the  incorrect architecture.   This causes  confusion in
+      configuration of all applications  that use FreeType2.  Instead,
+      use a prefix  to install the cross-build into  a separate system
+      tree, for example, `--prefix=/usr/local/mips-ip22-linux/'.
+
+      On the other hand, if the built  FreeType 2 library is used as a
+      part of the target system,  the prefix to install should reflect
+      the file system structure of the target system.
+
+
+    2.3. Library dependencies
+
+      FreeType normally depends on external libraries like `libpng' or
+      `libharfbuzz'.   The  easiest case  is  to  deactivate all  such
+      dependencies  using the  `--without-XXX' configuration  options.
+      However, if you  want to use those libraries,  you should ensure
+      that  they  are available  both  on  the  target system  and  as
+      (cross-compiled) libraries on the build system.
+
+      FreeType uses  `pkg-config' to find  most of the  libraries; the
+      other libraries it links to  are expected in the standard system
+      directories.   Since the  default pkg-config's  meta-information
+      files (like `harfbuzz.pc') of the build platform don't work, use
+      one of the two possible solutions below.
+
+        o Use pkg-config's meta-information files that are adjusted to
+          cross-compile  and  cross-link  with the  target  platform's
+          libraries.  Make sure those files are found before the build
+          system's default files.  Example:
+
+            ./configure \
+              --build=i386-unknown-freebsd \
+              --host=mips-ip22-linuxelf \
+              PKG_CONFIG_LIBDIR="/usr/local/mips-ip22-linux/lib/pkgconfig" \
+              [other options]
+
+          See the manpage of `pkg-config' for more details.
+
+        o Set variables like LIBPNG_LIBS  as additional options to the
+          `configure' script, overriding the values `pkg-config' would
+          provide.  `configure --help' shows the available environment
+          variables.  Example:
+
+            ./configure \
+              --build=i386-unknown-freebsd \
+              --host=mips-ip22-linuxelf \
+              LIBPNG_CFLAGS="-I/usr/local/mips-ip22-linux/include" \
+              LIBPNG_LIBS="-L/usr/local/mips-ip22-linux/lib -lpng12" \
+              [other options]
+
+
+  3. Building command
+  -------------------
+
+    If  the  configuration  finishes successfully,  invoking  GNU make
+    builds FreeType2.  Just say
+
+      make
+
+    or
+
+      gmake
+
+    depending on the name the GNU make binary actually has.
+
+
+  4. Installation
+  ---------------
+
+    Saying
+
+      make install
+
+    as usual to install FreeType2 into the directory tree specified by
+    the argument of the `--prefix' option.
+
+    As noted in section 2.2,  FreeType2  is sometimes configured to be
+    installed  into the  system directory  of the  target  system, and
+    should  not be installed  in the  cross-building system.   In such
+    cases, the  make variable `DESTDIR'  is useful to change  the root
+    directory in the installation.  For example, after
+
+      make DESTDIR=/mnt/target_system_root/ install
+
+    the built FreeType2 library files are installed into the directory
+    `/mnt/target_system_root/<prefix_in_configure>/lib'.
+
+
+  5. TODO
+  -------
+
+    Cross building between Cygwin (or MSys) and Unix must be tested.

+This document contains instructions how  to build the FreeType library
+on non-Unix systems with  the help of GNU Make.  Note  that if you are
+running  Cygwin  or  MinGW/MSYS  in Windows,  you  should  follow  the
+instructions in the file `INSTALL.UNIX' instead.
+
+
+  FreeType 2 includes a powerful and flexible build system that allows
+  you to  easily compile it on  a great variety of  platforms from the
+  command line.  To do so, just follow these simple instructions.
+
+  1. Install GNU Make
+  -------------------
+
+    Because  GNU Make  is  the  only Make  tool  supported to  compile
+    FreeType 2, you should install it on your machine.
+
+    The FreeType 2 build system relies on many features special to GNU
+    Make.
+
+    NEARLY ALL OTHER MAKE TOOLS  FAIL, INCLUDING `BSD MAKE', SO REALLY
+    INSTALL A RECENT VERSION OF GNU MAKE ON YOUR SYSTEM!
+
+    Note that  make++, a  make tool written  in Perl,  supports enough
+    features of GNU make to compile FreeType.  See
+
+      http://makepp.sourceforge.net
+
+    for more information;  you need version 2.0 or newer, and you must
+    pass option `--norc-substitution'.
+
+    Make sure that you are invoking GNU Make from the command line, by
+    typing something like:
+
+      make -v
+
+    to display its version number.
+
+    VERSION 3.81 OR NEWER IS NEEDED!
+
+
+  2. Invoke `make'
+  ----------------
+
+    Go to  the root  directory of FreeType  2, then simply  invoke GNU
+    Make from the command line.   This will launch the FreeType 2 host
+    platform  detection routines.   A summary  will be  displayed, for
+    example, on Win32.
+
+
+      ==============================================================
+      FreeType build system -- automatic system detection
+
+      The following settings are used:
+
+        platform                     windows
+        compiler                     gcc
+        configuration directory      .\builds\windows
+        configuration rules          .\builds\windows\w32-gcc.mk
+
+      If this does not correspond to your system or settings please
+      remove the file 'config.mk' from this directory then read the
+      INSTALL file for help.
+
+      Otherwise, simply type 'make' again to build the library
+      or 'make refdoc' to build the API reference (the latter needs
+      python).
+      =============================================================
+
+
+    If the detected settings correspond to your platform and compiler,
+    skip to step 5.  Note that if your platform is completely alien to
+    the build system, the detected platform will be `ansi'.
+
+
+  3. Configure the build system for a different compiler
+  ------------------------------------------------------
+
+    If the build system correctly detected your platform, but you want
+    to use a different compiler  than the one specified in the summary
+    (for most platforms, gcc is the default compiler), invoke GNU Make
+    with
+
+      make setup <compiler>
+
+    Examples:
+
+      to use Visual C++ on Win32, type:  `make setup visualc'
+      to use Borland C++ on Win32, type  `make setup bcc32'
+      to use Watcom C++ on Win32, type   `make setup watcom'
+      to use Intel C++ on Win32, type    `make setup intelc'
+      to use LCC-Win32 on Win32, type:   `make setup lcc'
+      to use Watcom C++ on OS/2, type    `make setup watcom'
+      to use VisualAge C++ on OS/2, type `make setup visualage'
+
+    The  <compiler> name to  use is  platform-dependent.  The  list of
+    available  compilers for  your  system is  available  in the  file
+    `builds/<system>/detect.mk'.
+
+    If you  are satisfied  by the new  configuration summary,  skip to
+    step 5.
+
+
+  4. Configure the build system for an unknown platform/compiler
+  --------------------------------------------------------------
+
+    The auto-detection/setup  phase of the build system  copies a file
+    to the current directory under the name `config.mk'.
+
+    For    example,    on    OS/2+gcc,    it   would    simply    copy
+    `builds/os2/os2-gcc.mk' to `./config.mk'.
+
+    If for  some reason your  platform isn't correctly  detected, copy
+    manually the configuration sub-makefile to `./config.mk' and go to
+    step 5.
+
+    Note  that  this file  is  a  sub-Makefile  used to  specify  Make
+    variables  for compiler  and linker  invocation during  the build.
+    You can  easily create your own  version from one  of the existing
+    configuration files,  then copy it to the  current directory under
+    the name `./config.mk'.
+
+
+  5. Build the library
+  --------------------
+
+    The auto-detection/setup  phase should have  copied a file  in the
+    current  directory,  called  `./config.mk'.   This  file  contains
+    definitions of various Make  variables used to invoke the compiler
+    and linker during the build.  [It has also generated a file called
+    `ftmodule.h'   in  the  objects   directory  (which   is  normally
+    `<toplevel>/objs/');  please read  the  file `docs/CUSTOMIZE'  for
+    customization of FreeType.]
+
+    To  launch  the build,  simply  invoke  GNU  Make again:  The  top
+    Makefile will detect the configuration file and run the build with
+    it.
+
+
+  Final note
+
+    The above instructions build a  _statically_ linked library of the
+    font engine in the `objs' directory.   On Windows, you can build a
+    DLL  either  with  MinGW  (within an  MSYS  shell,  following  the
+    instructions in `INSTALL.UNIX'), or you  use one of the Visual C++
+    project files; see  the  subdirectories  of `builds/windows'.  For
+    everything else,  you are on  your own,  and you might  follow the
+    instructions in `INSTALL.ANY' to create your own Makefiles.

+Please follow the instructions in  INSTALL.UNIX to install FreeType on
+Mac OS X.
+
+Currently  FreeType2 functions  based on  some deprecated  Carbon APIs
+return  `FT_Err_Unimplemented_Feature' always,  even  if FreeType2  is
+configured and  built on  the system that  deprecated Carbon  APIs are
+available.   To  enable  deprecated  FreeType2  functions  as  far  as
+possible, replace `src/base/ftmac.c' by `builds/mac/ftmac.c'.
+
+Starting with  Mac OS X  10.5, gcc  defaults the deployment  target to
+10.5.  In previous  versions of Mac OS X, this  defaulted to 10.1.  If
+you want your built binaries to run only on 10.5, this change does not
+concern you.  If  you want them to  also run on older  versions of Mac
+OS  X,   then  you   must  either  set   the  MACOSX_DEPLOYMENT_TARGET
+environment  variable  or  pass `-mmacosx-version-min'  to  gcc.   You
+should specify the oldest  version of Mac OS you want  the code to run
+on.  For example, if you use Bourne shell:
+
+  export MACOSX_DEPLOYMENT_TARGET=10.2
+
+or, if you use C shell:
+
+  setenv MACOSX_DEPLOYMENT_TARGET 10.2
+
+Alternatively, you could pass `-mmacosx-version-min=10.2' to gcc.
+
+Here the number 10.2 is the lowest version that the built binaries can
+run on.  In the  above cases, the built binaries will run  on Mac OS X
+10.2 and later, but _not_ earlier.  If you want to run on earlier, you
+have to set lower version, e.g., 10.0.
+
+For classic Mac OS (Mac OS 7, 8, 9) please refer to builds/mac/README.

+This  document contains  instructions  on how  to  build the  FreeType
+library on Unix  systems.  This also works for  emulations like Cygwin
+or MSys on Win32:
+
+
+  1. Ensure that you are using GNU Make
+  -------------------------------------
+
+    The FreeType build system  _exclusively_ works with GNU Make.  You
+    will  not be  able to  compile the  library with  the instructions
+    below using any other alternative (including BSD Make).
+
+    Check that you have GNU make by running the command:
+
+       make -v
+
+    This should dump some text that begins with:
+
+       GNU Make  <version number>
+       Copyright (C) <year> Free Software Foundation Inc.
+
+    Note that version  3.81 or higher is *required* or the  build will
+    fail.
+
+    It is also fine to have GNU Make under another name (e.g. 'gmake')
+    if you use the MAKE variable as described below.
+
+    As  a  special exception,  'makepp'  can  also  be used  to  build
+    FreeType 2.  See the file docs/MAKEPP for details.
+
+    For builds  with `cmake' please check file `CMakeLists.txt';  this
+    is a contributed file not directly supported by the FreeType team.
+
+
+  2. Regenerate the configure script if needed
+  --------------------------------------------
+
+    This only applies if you  are building a git snapshot or checkout,
+    *not* if you grabbed the sources of an official release.
+
+    You  need  to invoke  the  `autogen.sh'  script  in the  top-level
+    directory  in order  to  create the  `configure'  script for  your
+    platform.  Normally, this simply means typing:
+
+      sh autogen.sh
+
+    In case of problems, you  may need to install or upgrade Automake,
+    Autoconf or  Libtool.  See  README.git in the  top-level directory
+    for more information.
+
+
+  3. Build and install the library
+  --------------------------------
+
+    The following  should work  on all Unix  systems where  the `make'
+    command invokes GNU Make:
+
+      ./configure [options]
+      make
+      make install           (as root)
+
+    The default installation path  is `/usr/local'.  It can be changed
+    with the `--prefix=<path>' option.  Example:
+
+      ./configure --prefix=/usr
+
+    When using  a different command  to invoke GNU Make,  use the MAKE
+    variable.  For example,  if `gmake' is the command  to use on your
+    system, do something like:
+
+       MAKE=gmake ./configure [options]
+       gmake
+       gmake install            (as root)
+
+    If  this still doesn't  work, there  must be  a problem  with your
+    system (e.g., you are using a very old version of GNU Make).
+
+    It  is possible  to  compile FreeType  in  a different  directory.
+    Assuming the FreeType source  files in directory `/src/freetype' a
+    compilation in directory `foo' works as follows:
+
+      cd foo
+      /src/freetype/configure [options]
+      make
+      make install
+
+
+  3.1 Interdependency with HarfBuzz
+  .................................
+
+    Note that there  is a chicken-and-egg problem  currently since the
+    HarfBuzz library  (used by the  auto-hinter to improve  support of
+    OpenType  fonts)  depends on  FreeType,  which  can be  solved  as
+    follows in case HarfBuzz is not yet installed on your system.
+
+    1. Call    FreeType's     `configure'    script     with    option
+       `--without-harfbuzz', then compile and install FreeType.
+
+    2. Compile and install HarfBuzz.
+
+    3. Call    FreeType's    `configure'   script    without    option
+       `--without-harfbuzz' (after  executing `make  distclean'), then
+       compile and install FreeType again.

+How to build the FreeType 2 library on VMS
+-----------------------------------------
+
+It is actually very straightforward to install the FreeType 2 library.
+Just  execute vms_make.com from  the toplevel  directory to  build the
+library.  This procedure currently accepts the following options:
+
+DEBUG
+  Build the library with debug information and without optimization.
+
+lopts=<value>
+  Options to pass to the link command e.g. lopts=/traceback
+
+ccopt=<value>
+  Options to pass to the C compiler e.g. ccopt=/float=ieee
+
+In case you did download the demos, place them in a separate directory
+sharing the same top level  as the directory of FreeType 2  and follow
+the same instructions as above for  the demos from  there.  The  build
+process relies on this  to figure out  the location  of the FreeType 2
+include files.
+
+
+To rebuild  the  sources it is necessary to  have MMS/MMK installed on
+the system.
+
+The library is available in the directory
+
+  [.LIB]
+
+To  compile applications  using  FreeType  2 you  have  to define  the
+logical FREETYPE pointing to the directory
+
+  [.INCLUDE.FREETYPE]
+
+i.e., if  the directory in which  this INSTALL.VMS file  is located is
+$disk:[freetype] then define the logical with
+
+  define freetype $disk:[freetype.include.freetype]
+
+This version has  been tested with Compaq C  V6.2-006 on OpenVMS Alpha
+V7.2-1.
+
+
+  Any problems can be reported to
+
+    Jouk Jansen <joukj@hrem.stm.tudelft.nl> or
+    Martin P.J. Zinser <zinser@zinser.no-ip.info>

+The  FreeType 2  font  engine is  copyrighted  work and  cannot be  used
+legally  without a  software license.   In  order to  make this  project
+usable  to a vast  majority of  developers, we  distribute it  under two
+mutually exclusive open-source licenses.
+
+This means  that *you* must choose  *one* of the  two licenses described
+below, then obey  all its terms and conditions when  using FreeType 2 in
+any of your projects or products.
+
+  - The FreeType License, found in  the file `FTL.TXT', which is similar
+    to the original BSD license *with* an advertising clause that forces
+    you  to  explicitly cite  the  FreeType  project  in your  product's
+    documentation.  All  details are in the license  file.  This license
+    is  suited  to products  which  don't  use  the GNU  General  Public
+    License.
+
+    Note that  this license  is  compatible  to the  GNU General  Public
+    License version 3, but not version 2.
+
+  - The GNU General Public License version 2, found in  `GPLv2.TXT' (any
+    later version can be used  also), for programs which already use the
+    GPL.  Note  that the  FTL is  incompatible  with  GPLv2 due  to  its
+    advertisement clause.
+
+The contributed BDF and PCF drivers  come with a license similar to that
+of the X Window System.  It is compatible to the above two licenses (see
+file src/bdf/README and  src/pcf/README).  The same holds  for the files
+`fthash.c' and  `fthash.h'; their  code was  part of  the BDF  driver in
+earlier FreeType versions.
+
+The gzip module uses the zlib license (see src/gzip/zlib.h) which too is
+compatible to the above two licenses.
+
+The MD5 checksum support (only used for debugging in development builds)
+is in the public domain.

+This  file describes various  problems that  have been  encountered in
+compiling,  installing  and   running  FreeType  2.   Suggestions  for
+additions or other improvements to this file are welcome.
+
+----------------------------------------------------------------------
+
+Running Problems
+================
+
+
+* Some Type 1, Multiple Masters, and CID-keyed PostScript fonts aren't
+  handled correctly.
+
+-----
+
+Of course,  there might be  bugs in FreeType,  but some fonts based on
+the  PostScript  format can't  be handled indeed.  The reason  is that
+FreeType  doesn't contain a full  PostScript  interpreter  but applies
+pattern matching instead.  In case a font doesn't follow the  standard
+structure of the given font format, FreeType fails.  A typical example
+is Adobe's `Optima'  font family which  contains extra code  to switch
+between low and high resolution versions of the glyphs.
+
+It might be  possible to patch  FreeType in  some situations,  though.
+Please report failing fonts so that we investigate the problem and set
+up a list of such problematic fonts.
+
+
+* Why do identical FreeType  versions render differently  on different
+  platforms?
+
+-----
+
+Different distributions compile FreeType with different options.   The
+developer  version of  a  distribution's  FreeType  package,  which is
+needed to compile  your program  against FreeType,  includes the  file
+ftoption.h.  Compare  each platform's  copy of ftoption.h to  find the
+differences.
+
+
+----------------------------------------------------------------------
+
+
+Compilation Problems
+====================
+
+
+* I get an `internal compilation error' (ICE) while compiling FreeType
+  2.2.1 with Intel C++.
+
+  This has been reported for the following compiler version:
+
+    Intel(R) C++ Compiler for 32-bit applications,
+      Version 9.0 Build 20050430Z Package ID: W_CC_P_9.0.019
+
+-----
+
+The best solution is to update the compiler to version
+
+  Intel(R) C++ Compiler for 32-bit applications,
+    Version 9.1 Build 20060323Z Package ID: W_CC_P_9.1.022
+
+or newer.  If this isn't feasible, apply the following patch.

+Due  to our  use of  `libtool' to  generate and  install the  FreeType 2
+libraries on  Unix systems, as  well as  other historical events,  it is
+generally very  difficult to  know precisely which  release of  the font
+engine is installed on a given system.
+
+This file tries  to explain why and to document  ways to properly detect
+FreeType on Unix.
+
+
+1. Version and Release numbers
+------------------------------
+
+For each new  public release of FreeType 2, there  are generally *three*
+distinct `version' numbers to consider:
+
+  * The official FreeType 2 release number, like 2.3.1 or 2.4.10.
+
+  * The libtool (and  Unix) specific version number,  like 13.0.7.  This
+    is what `freetype-config --version' returns.
+
+  * The platform-specific  shared object  number, used for  example when
+    the library is installed as `/usr/lib/libfreetype.so.6.7.1'.
+
+The platform-specific  number is, unsurprisingly,  platform-specific and
+varies  with the  operating system  you are  using (several  variants of
+Linux, FreeBSD,  Solaris, etc.).  You  should thus _never_ use  it, even
+for simple tests.
+
+The libtool-specific  number does  not equal the  release number  but is
+tied to it.
+
+The release number is available  at *compile* time through the following
+macros defined in FT_FREETYPE_H:
+
+  - FREETYPE_MAJOR: major release number
+  - FREETYPE_MINOR: minor release number
+  - FREETYPE_PATCH: patch release number
+
+See below for a small autoconf fragment.
+
+The  release  number   is  also  available  at   *runtime*  through  the
+`FT_Library_Version' API.
+
+
+2. History
+----------
+
+The  following   table  gives,  for   all  releases  since   2.4.0,  the
+corresponding libtool number, as well  as the shared object number found
+on _most_ systems, but not all of them:

+This  file contains  a list  of various  font formats.   It gives  the
+reference document and whether it is supported in FreeType 2.
+
+Table fields
+------------
+
+  wrapper format
+    The format used to represent the font data.  In the table below it
+    is  used only  if the  font format  differs.  Possible  values are
+
+      SFNT  binary
+      PFB   binary
+      PS    a text header, followed by  binary or text data
+      LZW   compressed with  either `gzip' or `compress'
+      BZ2   compressed with `bzip2'.
+
+  font format
+    How the font is to be accessed, possibly after converting the file
+    type and wrapper  format into a generic form.   Bitmap formats are
+    `BDF',  `PCF', and  one form  of `WINFNT';  all others  are vector
+    formats.   `PS' indicates  third-order,  `TT' second-order  Bézier
+    curves.
+
+  font type
+    Sub-formats of the  font format.  `SBIT' and  `MACSBIT' are bitmap
+    formats,  `MM' and  `VAR' support  optical axes.   `CFF2' supports
+    optical axes also.
+
+  glyph access
+    If  not specified,  the glyph  access  is `standard'  to the  font
+    format.   Values are  `CID' for  CID-keyed fonts,  `SYNTHETIC' for
+    fonts that  are modified  versions of  other fonts  by means  of a
+    transformation matrix, and  `TYPE_0' for PS fonts which  are to be
+    accessed in a tree-like structure.
+
+  FreeType driver
+    The module in the FreeType library which handles the specific font
+    format.  A missing  entry means that FreeType  doesn't support the
+    font format (yet).
+
+
+Notes
+-----
+
+  The  SFNT  container  format also  provides  `collections'  (usually
+  having the file extension `.ttc'  or `.otc').  A collection contains
+  multiple font faces that share some tables to avoid redundancy, thus
+  reducing the file  size.  In FreeType, elements of  a collection can
+  be accessed with a proper face index.
+
+  Both  the GX  and the  OpenType 1.8  variation fonts  provide `named
+  instances'.  FreeType  maps them to  face indices (they can  also be
+  accessed with the standard MM interface).
+
+  Other  font  formats  (not  using the  SFNT  wrapper)  also  provide
+  multiple faces  within one  file; they are  marked with  an asterisk
+  (`*') in the table below.
+
+  FreeType can  be configured to  support Mac  files (on older  Mac OS
+  versions, a `file' is stored as a data and a resource fork, this is,
+  within two  separate data chunks).  If  a file can't be  opened as a
+  font, FreeType then checks whether it  is a resource fork, trying to
+  extract  the contained  font data  from  either a  `POST' or  `sfnt'
+  resource.
+
+
+Please  send additions  and/or  corrections to  wl@gnu.org  or to  the
+FreeType   developer's   list    at   freetype-devel@nongnu.org   (for
+subscribers only).   If you can  provide a  font example for  a format
+which isn't supported yet please send a mail too.

+.TH FREETYPE-CONFIG 1 "May 2018" "FreeType 2.9.1"
+.
+.
+.SH NAME
+.
+freetype-config \- Get information about a libfreetype installation
+.
+.
+.SH SYNOPSIS
+.
+.B freetype-config
+.RI [ options ]
+.
+.
+.SH DESCRIPTION
+.
+.B freetype-config
+returns information needed for compiling and linking programs with the
+FreeType library, such as linker flags and compilation parameters.
+.
+Alternatively, it can be used to query information about the
+FreeType library version installed on the system, such as the
+installation (directory path) prefix or the FreeType version number.
+.
+.PP
+If
+.BR pkg-config (1)
+is found in the path,
+.B freetype-config
+acts as a wrapper for
+.BR pkg-config .
+.
+.PP
+This program is part of the FreeType package.
+.
+.
+.SH OPTIONS
+.
+There are two types of options: output/display selection options, and
+path override options.
+.
+.
+.SS Output selection options
+.
+Only one of the output selection options should be given at each program
+invocation.
+.
+.TP
+.B \-\-prefix
+Return the prefix value of the installed FreeType library (the default
+prefix will be `/usr' in most cases for distribution-installed
+packages).
+.
+.TP
+.B \-\-exec-prefix
+Return the executable prefix value of the installed FreeType library
+(will often be the same as the prefix value).
+.
+.TP
+.B \-\-ftversion
+Return the FreeType version number, directly derived from file
+`freetype.h'.
+.
+.TP
+.B \-\-version
+Return the `libtool version' of the FreeType library.
+.
+.TP
+.B \-\-libtool
+Return the library name for linking with libtool.
+.
+.TP
+.B \-\-libs
+Return compiler flags for linking with the installed FreeType library.
+.
+.TP
+.B \-\-cflags
+Return compiler flags for compiling against the installed FreeType library.
+.
+.TP
+.B \-\-static
+Make command line options display flags for static linking.
+.
+.TP
+.B \-\-help
+Show help and exit.
+.
+.
+.SS Path override options
+.
+These affect any selected output option, except the libtool version
+returned by
+.BR \-\-version .
+.
+.TP
+.BI \-\-prefix= PREFIX
+Override
+.B \-\-prefix
+value with
+.IR PREFIX .
+.
+This also sets
+.BI \-\-exec-prefix= PREFIX
+if option
+.B \-\-exec-prefix
+is not explicitly given.
+.
+.TP
+.BI \-\-exec-prefix= EPREFIX
+Override
+.B \-\-exec-prefix
+value with
+.IR EPREFIX .
+.
+.
+.SH BUGS
+In case the libraries FreeType links to are located in non-standard
+directories, and
+.BR pkg-config (1)
+is not available, the output from option
+.B \-\-libs
+might be incomplete.
+.
+It is thus recommended to use the
+.BR pkg-config (1)
+interface instead, which is able to correctly resolve all dependencies.
+.
+.PP
+Setting
+.B \-\-exec-prefix
+(either explicitly or implicitly) might return incorrect results if
+combined with option
+.BR \-\-static .
+.
+The same problem can occur if you set the
+.B SYSROOT
+environment variable.

+
+
+This file  is an  attempt to explain  the internals of  the FreeType
+rasterizer.  The  rasterizer is of  quite general purpose  and could
+easily be integrated into other programs.

+
+
+I. Introduction
+===============
+
+  A  rasterizer is  a library  in charge  of converting  a vectorial
+  representation of a shape  into a bitmap.  The FreeType rasterizer
+  has  been  originally developed  to  render  the  glyphs found  in
+  TrueType  files, made  up  of segments  and second-order  Béziers.
+  Meanwhile it has been extended to render third-order Bézier curves
+  also.   This  document  is   an  explanation  of  its  design  and
+  implementation.
+
+  While  these explanations start  from the  basics, a  knowledge of
+  common rasterization techniques is assumed.
+
+
+II. Rendering Technology
+========================
+
+1. Requirements
+---------------
+
+  We  assume that  all scaling,  rotating, hinting,  etc.,  has been
+  already done.  The glyph is thus  described by a list of points in
+  the device space.
+
+  - All point coordinates  are in the 26.6 fixed  float format.  The
+    used orientation is:
+
+
+       ^ y
+       |         reference orientation
+       |
+       *----> x
+      0
+
+
+    `26.6' means  that 26 bits  are used for  the integer part  of a
+    value   and  6   bits  are   used  for   the   fractional  part.
+    Consequently, the `distance'  between two neighbouring pixels is
+    64 `units' (1 unit = 1/64th of a pixel).
+
+    Note  that, for  the rasterizer,  pixel centers  are  located at
+    integer   coordinates.   The   TrueType   bytecode  interpreter,
+    however, assumes that  the lower left edge of  a pixel (which is
+    taken  to be  a square  with  a length  of 1  unit) has  integer
+    coordinates.
+
+
+        ^ y                                        ^ y
+        |                                          |
+        |            (1,1)                         |      (0.5,0.5)

+

+
+
+    A pixel line in the target bitmap is called a `scanline'.
+
+  - A  glyph  is  usually  made  of several  contours,  also  called
+    `outlines'.  A contour is simply a closed curve that delimits an
+    outer or inner region of the glyph.  It is described by a series
+    of successive points of the points table.
+
+    Each point  of the glyph  has an associated flag  that indicates
+    whether  it is  `on' or  `off' the  curve.  Two  successive `on'
+    points indicate a line segment joining the two points.
+
+    One `off' point amidst two `on' points indicates a second-degree
+    (conic)  Bézier parametric  arc, defined  by these  three points
+    (the `off' point being the  control point, and the `on' ones the
+    start and end points).  Similarly, a third-degree (cubic) Bézier
+    curve  is described  by four  points (two  `off'  control points
+    between two `on' points).
+
+    Finally,  for  second-order curves  only,  two successive  `off'
+    points  forces the  rasterizer to  create, during  rendering, an
+    `on'  point amidst them,  at their  exact middle.   This greatly
+    facilitates the  definition of  successive Bézier arcs.
+
+  The parametric form of a second-order Bézier curve is:
+
+      P(t) = (1-t)^2*P1 + 2*t*(1-t)*P2 + t^2*P3
+
+      (P1 and P3 are the end points, P2 the control point.)
+
+  The parametric form of a third-order Bézier curve is:
+
+      P(t) = (1-t)^3*P1 + 3*t*(1-t)^2*P2 + 3*t^2*(1-t)*P3 + t^3*P4
+
+      (P1 and P4 are the end points, P2 and P3 the control points.)
+
+  For both formulae, t is a real number in the range [0..1].
+
+  Note  that the rasterizer  does not  use these  formulae directly.
+  They exhibit,  however, one very  useful property of  Bézier arcs:
+  Each  point of  the curve  is a  weighted average  of  the control
+  points.
+
+  As all weights  are positive and always sum up  to 1, whatever the
+  value  of t,  each arc  point lies  within the  triangle (polygon)
+  defined by the arc's three (four) control points.
+
+  In  the following,  only second-order  curves are  discussed since
+  rasterization of third-order curves is completely identical.
+
+  Here some samples for second-order curves.

+
+2. Profiles and Spans
+---------------------
+
+  The following is a basic explanation of the _kind_ of computations
+  made  by  the   rasterizer  to  build  a  bitmap   from  a  vector
+  representation.  Note  that the actual  implementation is slightly
+  different, due to performance tuning and other factors.
+
+  However, the following ideas remain  in the same category, and are
+  more convenient to understand.
+
+
+  a. Sweeping the Shape
+
+    The best way to fill a shape is to decompose it into a number of
+    simple  horizontal segments,  then turn  them on  in  the target
+    bitmap.  These segments are called `spans'.
+
+                __---__
+             _--       -_
+           _-            -
+          -               \
+         /                 \
+        /                   \
+       |                     \
+
+                __---__         Example: filling a shape
+             _----------_                with spans.
+           _--------------
+          ----------------\
+         /-----------------\    This is typically done from the top
+        /                   \   to the bottom of the shape, in a
+       |           |         \  movement called a `sweep'.
+                   V

+                __---__

+        /-------------------\
+       |---------------------\
+
+
+    In  order  to draw  a  span,  the  rasterizer must  compute  its
+    coordinates, which  are simply the x coordinates  of the shape's
+    contours, taken on the y scanlines.
+
+
+                   /---/    |---|   Note that there are usually

+
+
+  b. Decomposing Outlines into Profiles
+
+    For  each  scanline during  the  sweep,  we  need the  following
+    information:
+
+    o The  number of  spans on  the current  scanline, given  by the
+      number of  shape points  intersecting the scanline  (these are
+      the points a, b, c, and d in the above example).
+
+    o The x coordinates of these points.
+
+    x coordinates are  computed before the sweep, in  a phase called
+    `decomposition' which converts the glyph into *profiles*.
+
+    Put it simply, a `profile'  is a contour's portion that can only
+    be either ascending or descending,  i.e., it is monotonic in the
+    vertical direction (we also say  y-monotonic).  There is no such
+    thing as a horizontal profile, as we shall see.
+
+    Here are a few examples:
+
+
+      this square
+                                          1         2

+             <--__     P3                   up           down
+
+
+
+      A more general contour can be made of more than two profiles:
+
+              __     ^
+             /  |   /  ___          /    |
+            /   |     /   |        /     |       /     |
+           |    |    /   /    =>  |      v      /     /
+           |    |   |   |         |      |     ^     |
+        ^  |    |___|   |  |      ^   +  |  +  |  +  v
+        |  |           |   v      |                 |
+           |           |          |           up    |
+           |___________|          |    down         |
+
+                <--               up              down
+
+
+    Successive  profiles are  always joined  by  horizontal segments
+    that are not part of the profiles themselves.
+
+    For  the  rasterizer,  a  profile  is  simply  an  *array*  that
+    associates  one  horizontal *pixel*  coordinate  to each  bitmap
+    *scanline*  crossed  by  the  contour's section  containing  the
+    profile.  Note that profiles are *oriented* up or down along the
+    glyph's original flow orientation.
+
+    In other graphics libraries, profiles are also called `edges' or
+    `edgelists'.
+
+
+  c. The Render Pool
+
+    FreeType  has been designed  to be  able to  run well  on _very_
+    light systems, including embedded systems with very few memory.
+
+    A render pool  will be allocated once; the  rasterizer uses this
+    pool for all  its needs by managing this  memory directly in it.
+    The  algorithms that are  used for  profile computation  make it
+    possible to use  the pool as a simple  growing heap.  This means
+    that this  memory management is  actually quite easy  and faster
+    than any kind of malloc()/free() combination.
+
+    Moreover,  we'll see  later that  the rasterizer  is  able, when
+    dealing with profiles too large  and numerous to lie all at once
+    in  the render  pool, to  immediately decompose  recursively the
+    rendering process  into independent sub-tasks,  each taking less
+    memory to be performed (see `sub-banding' below).
+
+    The  render pool doesn't  need to  be large.   A 4KByte  pool is
+    enough for nearly all renditions, though nearly 100% slower than
+    a more comfortable 16KByte or 32KByte pool (that was tested with
+    complex glyphs at sizes over 500 pixels).
+
+
+  d. Computing Profiles Extents
+
+    Remember that a profile is an array, associating a _scanline_ to
+    the x pixel coordinate of its intersection with a contour.
+
+    Though it's not exactly how the FreeType rasterizer works, it is
+    convenient  to think  that  we need  a  profile's height  before
+    allocating it in the pool and computing its coordinates.
+
+    The profile's height  is the number of scanlines  crossed by the
+    y-monotonic section of a contour.  We thus need to compute these
+    sections from  the vectorial description.  In order  to do that,
+    we are  obliged to compute all  (local and global)  y extrema of
+    the glyph (minima and maxima).
+
+
+           P2             For instance, this triangle has only
+                          two y-extrema, which are simply
+           |\
+           | \               P2.y  as a vertical maximum
+          |   \              P3.y  as a vertical minimum
+          |    \
+         |      \            P1.y is not a vertical extremum (though
+         |       \           it is a horizontal minimum, which we
+      P1 ---___   \          don't need).
+               ---_\
+                     P3
+
+
+    Note  that the  extrema are  expressed  in pixel  units, not  in
+    scanlines.   The triangle's  height  is certainly  (P3.y-P2.y+1)
+    pixel  units,   but  its  profiles'  heights   are  computed  in
+    scanlines.  The exact conversion is simple:
+
+      - min scanline = FLOOR  ( min y )
+      - max scanline = CEILING( max y )
+
+    A problem  arises with Bézier  Arcs.  While a segment  is always
+    necessarily y-monotonic (i.e.,  flat, ascending, or descending),
+    which makes extrema computations easy,  the ascent of an arc can
+    vary between its control points.
+
+
+                          P2
+                         *
+                                       # on curve
+                                       * off curve
+                   __-x--_
+                _--       -_
+          P1  _-            -          A non y-monotonic Bézier arc.
+             #               \
+                              -        The arc goes from P1 to P3.
+                               \
+                                \  P3
+                                 #
+
+
+    We first  need to be  able to easily detect  non-monotonic arcs,
+    according to  their control points.  I will  state here, without
+    proof, that the monotony condition can be expressed as:
+
+      P1.y <= P2.y <= P3.y   for an ever-ascending arc
+
+      P1.y >= P2.y >= P3.y   for an ever-descending arc
+
+    with the special case of
+
+      P1.y = P2.y = P3.y     where the arc is said to be `flat'.
+
+    As  you can  see, these  conditions can  be very  easily tested.
+    They are, however, extremely important, as any arc that does not
+    satisfy them necessarily contains an extremum.
+
+    Note  also that  a monotonic  arc can  contain an  extremum too,
+    which is then one of its `on' points:
+
+
+        P1           P2
+          #---__   *         P1P2P3 is ever-descending, but P1
+                -_           is an y-extremum.
+                  -
+           ---_    \
+               ->   \
+                     \  P3
+                      #
+
+
+    Let's go back to our previous example:
+
+
+                          P2
+                         *
+                                       # on curve
+                                       * off curve
+                   __-x--_
+                _--       -_
+          P1  _-            -          A non-y-monotonic Bézier arc.
+             #               \
+                              -        Here we have
+                               \              P2.y >= P1.y &&
+                                \  P3         P2.y >= P3.y      (!)
+                                 #
+
+
+    We need to  compute the vertical maximum of this  arc to be able
+    to compute a profile's height (the point marked by an `x').  The
+    arc's equation indicates that  a direct computation is possible,
+    but  we rely  on a  different technique,  which use  will become
+    apparent soon.
+
+    Bézier  arcs have  the  special property  of  being very  easily
+    decomposed into two sub-arcs,  which are themselves Bézier arcs.
+    Moreover, it is easy to prove that there is at most one vertical
+    extremum on  each Bézier arc (for  second-degree curves; similar
+    conditions can be found for third-order arcs).
+
+    For instance,  the following arc  P1P2P3 can be  decomposed into
+    two sub-arcs Q1Q2Q3 and R1R2R3:
+
+
+                    P2
+                   *

+                                    * off curve
+
+
+                                    original Bézier arc P1P2P3.

+          -                 -         Q2 = (P1+P2)/2  R2 = (P2+P3)/2
+         /                   \
+        /                     \            Q3 = R1 = (Q2+R2)/2
+       #                       #
+     Q1                         R3    Note that Q2, R2, and Q3=R1
+                                      are on a single line which is
+                                      tangent to the curve.
+
+
+    We have then decomposed  a non-y-monotonic Bézier curve into two
+    smaller sub-arcs.  Note that in the above drawing, both sub-arcs
+    are monotonic, and that the extremum is then Q3=R1.  However, in
+    a  more general  case,  only  one sub-arc  is  guaranteed to  be
+    monotonic.  Getting back to our former example:
+
+
+                    Q2
+                   *
+
+                   __-x--_ R1
+                _--       #_
+          Q1  _-        Q3  -   R2
+             #               \ *
+                              -
+                               \
+                                \  R3
+                                 #
+
+
+    Here, we see that,  though Q1Q2Q3 is still non-monotonic, R1R2R3
+    is ever  descending: We  thus know that  it doesn't  contain the
+    extremum.  We can then re-subdivide Q1Q2Q3 into two sub-arcs and
+    go  on recursively,  stopping  when we  encounter two  monotonic
+    subarcs, or when the subarcs become simply too small.
+
+    We  will finally  find  the vertical  extremum.   Note that  the
+    iterative process of finding an extremum is called `flattening'.
+
+
+  e. Computing Profiles Coordinates
+
+    Once we have the height of each profile, we are able to allocate
+    it in the render pool.   The next task is to compute coordinates
+    for each scanline.
+
+    In  the case  of segments,  the computation  is straightforward,
+    using  the  Euclidean   algorithm  (also  known  as  Bresenham).
+    However, for Bézier arcs, the job is a little more complicated.
+
+    We assume  that all Béziers that  are part of a  profile are the
+    result of  flattening the curve,  which means that they  are all
+    y-monotonic (ascending  or descending, and never  flat).  We now
+    have  to compute the  intersections of  arcs with  the profile's
+    scanlines.  One  way is  to use a  similar scheme  to flattening
+    called `stepping'.
+
+
+                                 Consider this arc, going from P1 to
+      ---------------------      P3.  Suppose that we need to
+                                 compute its intersections with the
+                                 drawn scanlines.  As already
+      ---------------------      mentioned this can be done
+                                 directly, but the involved
+          * P2         _---# P3  algorithm is far too slow.
+      ------------- _--  --
+                  _-
+                _/               Instead, it is still possible to
+      ---------/-----------      use the decomposition property in
+              /                  the same recursive way, i.e.,
+             |                   subdivide the arc into subarcs
+      ------|--------------      until these get too small to cross
+            |                    more than one scanline!
+           |
+      -----|---------------      This is very easily done using a
+          |                      rasterizer-managed stack of
+          |                      subarcs.
+          # P1
+
+
+  f. Sweeping and Sorting the Spans
+
+    Once all our profiles have  been computed, we begin the sweep to
+    build (and fill) the spans.
+
+    As both the  TrueType and Type 1 specifications  use the winding
+    fill  rule (but  with opposite  directions), we  place,  on each
+    scanline, the present profiles in two separate lists.
+
+    One  list,  called  the  `left'  one,  only  contains  ascending
+    profiles, while  the other `right' list  contains the descending
+    profiles.
+
+    As  each glyph  is made  of  closed curves,  a simple  geometric
+    property ensures that  the two lists contain the  same number of
+    elements.
+
+    Creating spans is thus straightforward:
+
+    1. We sort each list in increasing horizontal order.
+
+    2. We pair  each value of  the left list with  its corresponding
+       value in the right list.
+
+
+                   /     /  |   |          For example, we have here
+                  /     /   |   |          four profiles.  Two of
+                >/     /    |   |  |       them are ascending (1 &
+              1//     /   ^ |   |  | 2     3), while the two others
+              //     //  3| |   |  v       are descending (2 & 4).
+              /     //4   | |   |          On the given scanline,
+           a /     /<       |   |          the left list is (1,3),
+      - - - *-----* - - - - *---* - - y -  and the right one is
+           /     / b       c|   |d         (4,2) (sorted).
+
+                                   There are then two spans, joining
+                                   1 to 4 (i.e. a-b) and 3 to 2
+                                   (i.e. c-d)!
+
+
+    Sorting doesn't necessarily  take much time, as in  99 cases out
+    of 100, the lists' order is  kept from one scanline to the next.
+    We can  thus implement it  with two simple  singly-linked lists,
+    sorted by a classic bubble-sort, which takes a minimum amount of
+    time when the lists are already sorted.
+
+    A  previous  version  of  the  rasterizer  used  more  elaborate
+    structures, like arrays to  perform `faster' sorting.  It turned
+    out that  this old scheme is  not faster than  the one described
+    above.
+
+    Once the spans  have been `created', we can  simply draw them in
+    the target bitmap.

+
+<p>A handle to a FreeType library instance. Each &lsquo;library&rsquo; is completely independent from the others; it is the &lsquo;root&rsquo; of a set of objects like fonts, faces, sizes, etc.</p>
+<p>It also embeds a memory manager (see <a href="ft2-system_interface.html#FT_Memory">FT_Memory</a>), as well as a scan-line converter object (see <a href="ft2-raster.html#FT_Raster">FT_Raster</a>).</p>
+<p>In multi-threaded applications it is easiest to use one &lsquo;FT_Library&rsquo; object per thread. In case this is too cumbersome, a single &lsquo;FT_Library&rsquo; object across threads is possible also (since FreeType version 2.5.6), as long as a mutex lock is used around <a href="ft2-base_interface.html#FT_New_Face">FT_New_Face</a> and <a href="ft2-base_interface.html#FT_Done_Face">FT_Done_Face</a>.</p>
+
+<h4>note</h4>
+<p>Library objects are normally created by <a href="ft2-base_interface.html#FT_Init_FreeType">FT_Init_FreeType</a>, and destroyed with <a href="ft2-base_interface.html#FT_Done_FreeType">FT_Done_FreeType</a>. If you need reference-counting (cf. <a href="ft2-module_management.html#FT_Reference_Library">FT_Reference_Library</a>), use <a href="ft2-module_management.html#FT_New_Library">FT_New_Library</a> and <a href="ft2-module_management.html#FT_Done_Library">FT_Done_Library</a>.</p>

+  <span class="keyword">typedef</span> <span class="keyword">struct</span> FT_FaceRec_*  <b>FT_Face</b>;
+</pre>
+
+<p>A handle to a typographic face object. A face object models a given typeface, in a given style.</p>
+
+<h4>note</h4>
+<p>A face object also owns a single <a href="ft2-base_interface.html#FT_GlyphSlot">FT_GlyphSlot</a> object, as well as one or more <a href="ft2-base_interface.html#FT_Size">FT_Size</a> objects.</p>
+<p>Use <a href="ft2-base_interface.html#FT_New_Face">FT_New_Face</a> or <a href="ft2-base_interface.html#FT_Open_Face">FT_Open_Face</a> to create a new face object from a given filepath or a custom input stream.</p>
+<p>Use <a href="ft2-base_interface.html#FT_Done_Face">FT_Done_Face</a> to destroy it (along with its slot and sizes).</p>
+<p>An &lsquo;FT_Face&rsquo; object can only be safely used from one thread at a time. Similarly, creation and destruction of &lsquo;FT_Face&rsquo; with the same <a href="ft2-base_interface.html#FT_Library">FT_Library</a> object can only be done from one thread at a time. On the other hand, functions like <a href="ft2-base_interface.html#FT_Load_Glyph">FT_Load_Glyph</a> and its siblings are thread-safe and do not need the lock to be held as long as the same &lsquo;FT_Face&rsquo; object is not used from multiple threads at the same time.</p>

+<p>An <a href="ft2-base_interface.html#FT_Face">FT_Face</a> has one <i>active</i> <a href="ft2-base_interface.html#FT_Size">FT_Size</a> object that is used by functions like <a href="ft2-base_interface.html#FT_Load_Glyph">FT_Load_Glyph</a> to determine the scaling transformation that in turn is used to load and hint glyphs and metrics.</p>
+<p>You can use <a href="ft2-base_interface.html#FT_Set_Char_Size">FT_Set_Char_Size</a>, <a href="ft2-base_interface.html#FT_Set_Pixel_Sizes">FT_Set_Pixel_Sizes</a>, <a href="ft2-base_interface.html#FT_Request_Size">FT_Request_Size</a> or even <a href="ft2-base_interface.html#FT_Select_Size">FT_Select_Size</a> to change the content (i.e., the scaling values) of the active <a href="ft2-base_interface.html#FT_Size">FT_Size</a>.</p>
+<p>You can use <a href="ft2-sizes_management.html#FT_New_Size">FT_New_Size</a> to create additional size objects for a given <a href="ft2-base_interface.html#FT_Face">FT_Face</a>, but they won't be used by other functions until you activate it through <a href="ft2-sizes_management.html#FT_Activate_Size">FT_Activate_Size</a>.

+</pre>
+
+<p>A handle to a character map (usually abbreviated to &lsquo;charmap&rsquo;). A charmap is used to translate character codes in a given encoding into glyph indexes for its parent's face. Some font formats may provide several charmaps per font.</p>
+<p>Each face object owns zero or more charmaps, but only one of them can be &lsquo;active&rsquo;, providing the data used by <a href="ft2-base_interface.html#FT_Get_Char_Index">FT_Get_Char_Index</a> or <a href="ft2-base_interface.html#FT_Load_Char">FT_Load_Char</a>.</p>
+<p>The list of available charmaps in a face is available through the &lsquo;face-&gt;num_charmaps&rsquo; and &lsquo;face-&gt;charmaps&rsquo; fields of <a href="ft2-base_interface.html#FT_FaceRec">FT_FaceRec</a>.</p>
+<p>The currently active charmap is available as &lsquo;face-&gt;charmap&rsquo;. You should call <a href="ft2-base_interface.html#FT_Set_Charmap">FT_Set_Charmap</a> to change it.</p>
+
+<h4>note</h4>
+<p>When a new face is created (either through <a href="ft2-base_interface.html#FT_New_Face">FT_New_Face</a> or <a href="ft2-base_interface.html#FT_Open_Face">FT_Open_Face</a>), the library looks for a Unicode charmap within the list and automatically activates it.

+<h4>note</h4>
+<p>By default, FreeType enables a Unicode charmap and tags it with FT_ENCODING_UNICODE when it is either provided or can be generated from PostScript glyph name dictionaries in the font file. All other encodings are considered legacy and tagged only if explicitly defined in the font file. Otherwise, FT_ENCODING_NONE is used.</p>
+<p>FT_ENCODING_NONE is set by the BDF and PCF drivers if the charmap is neither Unicode nor ISO-8859-1 (otherwise it is set to FT_ENCODING_UNICODE). Use <a href="ft2-bdf_fonts.html#FT_Get_BDF_Charset_ID">FT_Get_BDF_Charset_ID</a> to find out which encoding is really present. If, for example, the &lsquo;cs_registry&rsquo; field is &lsquo;KOI8&rsquo; and the &lsquo;cs_encoding&rsquo; field is &lsquo;R&rsquo;, the font is encoded in KOI8-R.</p>
+<p>FT_ENCODING_NONE is always set (with a single exception) by the winfonts driver. Use <a href="ft2-winfnt_fonts.html#FT_Get_WinFNT_Header">FT_Get_WinFNT_Header</a> and examine the &lsquo;charset&rsquo; field of the <a href="ft2-winfnt_fonts.html#FT_WinFNT_HeaderRec">FT_WinFNT_HeaderRec</a> structure to find out which encoding is really present. For example, <a href="ft2-winfnt_fonts.html#FT_WinFNT_ID_XXX">FT_WinFNT_ID_CP1251</a> (204) means Windows code page 1251 (for Russian).</p>
+<p>FT_ENCODING_NONE is set if &lsquo;platform_id&rsquo; is <a href="ft2-truetype_tables.html#TT_PLATFORM_XXX">TT_PLATFORM_MACINTOSH</a> and &lsquo;encoding_id&rsquo; is not &lsquo;TT_MAC_ID_ROMAN&rsquo; (otherwise it is set to FT_ENCODING_APPLE_ROMAN).</p>
+<p>If &lsquo;platform_id&rsquo; is <a href="ft2-truetype_tables.html#TT_PLATFORM_XXX">TT_PLATFORM_MACINTOSH</a>, use the function <a href="ft2-truetype_tables.html#FT_Get_CMap_Language_ID">FT_Get_CMap_Language_ID</a> to query the Mac language ID that may be needed to be able to distinguish Apple encoding variants. See</p>
+<p><a href="https://www.unicode.org/Public/MAPPINGS/VENDORS/APPLE/Readme.txt">https://www.unicode.org/Public/MAPPINGS/VENDORS/APPLE/Readme.txt</a></p>
+<p>to get an idea how to do that. Basically, if the language ID is&nbsp;0, don't use it, otherwise subtract 1 from the language ID. Then examine &lsquo;encoding_id&rsquo;. If, for example, &lsquo;encoding_id&rsquo; is &lsquo;TT_MAC_ID_ROMAN&rsquo; and the language ID (minus&nbsp;1) is &lsquo;TT_MAC_LANGID_GREEK&rsquo;, it is the Greek encoding, not Roman. &lsquo;TT_MAC_ID_ARABIC&rsquo; with &lsquo;TT_MAC_LANGID_FARSI&rsquo; means the Farsi variant the Arabic encoding.</p>

+<p>Note that due to glyph hinting and the selected rendering mode these values are usually not exact; consequently, they must be treated as unreliable with an error margin of at least one pixel!</p>
+<p>Indeed, the only way to get the exact metrics is to render <i>all</i> glyphs. As this would be a definite performance hit, it is up to client applications to perform such computations.</p>

+<p><b>TrueType</b> <b>fonts</b> <b>with</b> <b>native</b> <b>bytecode</b> <b>hinting</b></p>
+<p>All applications that handle TrueType fonts with native hinting must be aware that TTFs expect different rounding of vertical font dimensions.

+<p>Only the application knows <i>in</i> <i>advance</i> that it is going to use native hinting for TTFs! FreeType, on the other hand, selects the hinting mode not at the time of creating an <a href="ft2-base_interface.html#FT_Size">FT_Size</a> object but much later, namely while calling <a href="ft2-base_interface.html#FT_Load_Glyph">FT_Load_Glyph</a>.</p>

+<h4>note</h4>
+<p>If <a href="ft2-base_interface.html#FT_Load_Glyph">FT_Load_Glyph</a> is called with default flags (see <a href="ft2-base_interface.html#FT_LOAD_XXX">FT_LOAD_DEFAULT</a>) the glyph image is loaded in the glyph slot in its native format (e.g., an outline glyph for TrueType and Type&nbsp;1 formats). [Since 2.9] The prospective bitmap metrics are calculated according to <a href="ft2-base_interface.html#FT_LOAD_TARGET_XXX">FT_LOAD_TARGET_XXX</a> and other flags even for the outline glyph, even if <a href="ft2-base_interface.html#FT_LOAD_XXX">FT_LOAD_RENDER</a> is not set.</p>
+<p>This image can later be converted into a bitmap by calling <a href="ft2-base_interface.html#FT_Render_Glyph">FT_Render_Glyph</a>. This function searches the current renderer for the native image's format, then invokes it.</p>
+<p>The renderer is in charge of transforming the native image through the slot's face transformation fields, then converting it into a bitmap that is returned in &lsquo;slot-&gt;bitmap&rsquo;.</p>
+<p>Note that &lsquo;slot-&gt;bitmap_left&rsquo; and &lsquo;slot-&gt;bitmap_top&rsquo; are also used to specify the position of the bitmap relative to the current pen position (e.g., coordinates (0,0) on the baseline). Of course, &lsquo;slot-&gt;format&rsquo; is also changed to <a href="ft2-basic_types.html#FT_Glyph_Format">FT_GLYPH_FORMAT_BITMAP</a>.</p>
+<p>Here is a small pseudo code fragment that shows how to use &lsquo;lsb_delta&rsquo; and &lsquo;rsb_delta&rsquo; to do fractional positioning of glyphs:</p>
+<pre class="colored">
+  FT_GlyphSlot  slot     = face-&gt;glyph;
+  FT_Pos        origin_x = 0;
+
+
+  for all glyphs do
+    &lt;load glyph with `FT_Load_Glyph'&gt;
+
+    FT_Outline_Translate( slot-&gt;outline, origin_x &amp; 63, 0 );
+
+    &lt;save glyph image, or render glyph, or ...&gt;
+
+    &lt;compute kern between current and next glyph
+     and add it to `origin_x'&gt;
+
+    origin_x += slot-&gt;advance.x;
+    origin_x += slot-&gt;rsb_delta - slot-&gt;lsb_delta;
+  endfor
+</pre>
+<p>Here is another small pseudo code fragment that shows how to use &lsquo;lsb_delta&rsquo; and &lsquo;rsb_delta&rsquo; to improve integer positioning of glyphs:</p>
+<pre class="colored">
+  FT_GlyphSlot  slot           = face-&gt;glyph;
+  FT_Pos        origin_x       = 0;
+  FT_Pos        prev_rsb_delta = 0;
+
+
+  for all glyphs do
+    &lt;compute kern between current and previous glyph
+     and add it to `origin_x'&gt;
+
+    &lt;load glyph with `FT_Load_Glyph'&gt;
+
+    if ( prev_rsb_delta - slot-&gt;lsb_delta &gt;  32 )
+      origin_x -= 64;
+    else if ( prev_rsb_delta - slot-&gt;lsb_delta &lt; -31 )
+      origin_x += 64;
+
+    prev_rsb_delta = slot-&gt;rsb_delta;
+
+    &lt;save glyph image, or render glyph, or ...&gt;
+
+    origin_x += slot-&gt;advance.x;
+  endfor
+</pre>
+<p>If you use strong auto-hinting, you <b>must</b> apply these delta values! Otherwise you will experience far too large inter-glyph spacing at small rendering sizes in most cases. Note that it doesn't harm to use the above code for other hinting modes also, since the delta values are zero then.</p>

For non-variation fonts, bits 16-30 are ignored. Assuming that you want to access the third named instance in face&nbsp;4, &lsquo;face_index&rsquo; should be set to 0x00030004.

In general, if the &lsquo;face_index&rsquo; argument is negative, the function's return value is&nbsp;0 if the font format is recognized, or non-zero otherwise. The function allocates a more or less empty face handle in &lsquo;*aface&rsquo; (if &lsquo;aface&rsquo; isn't NULL); the only two useful fields in this special case are &lsquo;face-&gt;num_faces&rsquo; and &lsquo;face-&gt;style_flags&rsquo;.

+<p>To get meaningful results, font scaling values must be set with functions like <a href="ft2-base_interface.html#FT_Set_Char_Size">FT_Set_Char_Size</a> before calling &lsquo;FT_Render_Glyph&rsquo;.</p>
+<p>When FreeType outputs a bitmap of a glyph, it really outputs an alpha coverage map. If a pixel is completely covered by a filled-in outline, the bitmap contains 0xFF at that pixel, meaning that 0xFF/0xFF fraction of that pixel is covered, meaning the pixel is 100% black (or 0% bright). If a pixel is only 50% covered (value 0x80), the pixel is made 50% black (50% bright or a middle shade of grey). 0% covered means 0% black (100% bright or white).</p>
+<p>On high-DPI screens like on smartphones and tablets, the pixels are so small that their chance of being completely covered and therefore completely black are fairly good. On the low-DPI screens, however, the situation is different. The pixels are too large for most of the details of a glyph and shades of gray are the norm rather than the exception.</p>
+<p>This is relevant because all our screens have a second problem: they are not linear. 1&nbsp;+&nbsp;1 is not&nbsp;2. Twice the value does not result in twice the brightness. When a pixel is only 50% covered, the coverage map says 50% black, and this translates to a pixel value of 128 when you use 8&nbsp;bits per channel (0-255). However, this does not translate to 50% brightness for that pixel on our sRGB and gamma&nbsp;2.2 screens. Due to their non-linearity, they dwell longer in the darks and only a pixel value of about 186 results in 50% brightness -- 128 ends up too dark on both bright and dark backgrounds. The net result is that dark text looks burnt-out, pixely and blotchy on bright background, bright text too frail on dark backgrounds, and colored text on colored background (for example, red on green) seems to have dark halos or &lsquo;dirt&rsquo; around it. The situation is especially ugly for diagonal stems like in &lsquo;w&rsquo; glyph shapes where the quality of FreeType's anti-aliasing depends on the correct display of grays. On high-DPI screens where smaller, fully black pixels reign supreme, this doesn't matter, but on our low-DPI screens with all the gray shades, it does. 0% and 100% brightness are the same things in linear and non-linear space, just all the shades in-between aren't.</p>
+<p>The blending function for placing text over a background is</p>
+<pre class="colored">
+  dst = alpha * src + (1 - alpha) * dst    ,
+</pre>
+<p>which is known as the OVER operator.</p>
+<p>To correctly composite an antialiased pixel of a glyph onto a surface,</p>
+<p>1. take the foreground and background colors (e.g., in sRGB space) and apply gamma to get them in a linear space,</p>
+<p>2. use OVER to blend the two linear colors using the glyph pixel as the alpha value (remember, the glyph bitmap is an alpha coverage bitmap), and</p>
+<p>3. apply inverse gamma to the blended pixel and write it back to the image.</p>
+<p>Internal testing at Adobe found that a target inverse gamma of&nbsp;1.8 for step&nbsp;3 gives good results across a wide range of displays with an sRGB gamma curve or a similar one.</p>
+<p>This process can cost performance. There is an approximation that does not need to know about the background color; see <a href="https://bel.fi/alankila/lcd/">https://bel.fi/alankila/lcd/</a> and <a href="https://bel.fi/alankila/lcd/alpcor.html">https://bel.fi/alankila/lcd/alpcor.html</a> for details.</p>
+<p><b>ATTENTION</b>: Linear blending is even more important when dealing with subpixel-rendered glyphs to prevent color-fringing! A subpixel-rendered glyph must first be filtered with a filter that gives equal weight to the three color primaries and does not exceed a sum of 0x100, see section &lsquo;<a href="ft2-lcd_filtering.html#lcd_filtering">LCD Filtering</a>&rsquo;. Then the only difference to gray linear blending is that subpixel-rendered linear blending is done 3&nbsp;times per pixel: red foreground subpixel to red background subpixel and so on for green and blue.</p>

+<p>Should you define FT_CONFIG_OPTION_SUBPIXEL_RENDERING in your &lsquo;ftoption.h&rsquo;, which enables patented ClearType-style rendering, the LCD-optimized glyph bitmaps should be filtered to reduce color fringes inherent to this technology. You can either set up LCD filtering with <a href="ft2-lcd_filtering.html#FT_Library_SetLcdFilter">FT_Library_SetLcdFilter</a> or <a href="ft2-base_interface.html#FT_Face_Properties">FT_Face_Properties</a>, or do the filtering yourself. The default FreeType LCD rendering technology does not require filtering.</p>
+<p>The selected render mode only affects vector glyphs of a font. Embedded bitmaps often have a different pixel mode like <a href="ft2-basic_types.html#FT_Pixel_Mode">FT_PIXEL_MODE_MONO</a>. You can use <a href="ft2-bitmap_handling.html#FT_Bitmap_Convert">FT_Bitmap_Convert</a> to transform them into 8-bit pixmaps.</p>

+<p>2. If no embedded bitmap is searched for or found, FreeType looks for a scalable outline. If one is found, it is loaded from the font file, scaled to device pixels, then &lsquo;hinted&rsquo; to the pixel grid in order to optimize it. The outline data can be accessed from the glyph slot (see note below).</p>

+<h4>note</h4>
+<p>By default, hinting is enabled and the font's native hinter (see <a href="ft2-base_interface.html#FT_FACE_FLAG_XXX">FT_FACE_FLAG_HINTER</a>) is preferred over the auto-hinter. You can disable hinting by setting <a href="ft2-base_interface.html#FT_LOAD_XXX">FT_LOAD_NO_HINTING</a> or change the precedence by setting <a href="ft2-base_interface.html#FT_LOAD_XXX">FT_LOAD_FORCE_AUTOHINT</a>. You can also set <a href="ft2-base_interface.html#FT_LOAD_XXX">FT_LOAD_NO_AUTOHINT</a> in case you don't want the auto-hinter to be used at all.</p>
+<p>See the description of <a href="ft2-base_interface.html#FT_FACE_FLAG_XXX">FT_FACE_FLAG_TRICKY</a> for a special exception (affecting only a handful of Asian fonts).</p>
+<p>Besides deciding which hinter to use, you can also decide which hinting algorithm to use. See <a href="ft2-base_interface.html#FT_LOAD_TARGET_XXX">FT_LOAD_TARGET_XXX</a> for details.</p>
+<p>Note that the auto-hinter needs a valid Unicode cmap (either a native one or synthesized by FreeType) for producing correct results. If a font provides an incorrect mapping (for example, assigning the character code U+005A, LATIN CAPITAL LETTER Z, to a glyph depicting a mathematical integral sign), the auto-hinter might produce useless results.</p>

+<h4>note</h4>
+<p>You should use only <i>one</i> of the FT_LOAD_TARGET_XXX values in your &lsquo;load_flags&rsquo;. They can't be ORed.</p>
+<p>If <a href="ft2-base_interface.html#FT_LOAD_XXX">FT_LOAD_RENDER</a> is also set, the glyph is rendered in the corresponding mode (i.e., the mode that matches the used algorithm best). An exception is FT_LOAD_TARGET_MONO since it implies <a href="ft2-base_interface.html#FT_LOAD_XXX">FT_LOAD_MONOCHROME</a>.</p>
+<p>You can use a hinting algorithm that doesn't correspond to the same rendering mode. As an example, it is possible to use the &lsquo;light&rsquo; hinting algorithm and have the results rendered in horizontal LCD pixel mode, with code like</p>
+<pre class="colored">
+  FT_Load_Glyph( face, glyph_index,

+</pre>
+<p>In general, you should stick with one rendering mode. For example, switching between <a href="ft2-base_interface.html#FT_LOAD_TARGET_XXX">FT_LOAD_TARGET_NORMAL</a> and <a href="ft2-base_interface.html#FT_LOAD_TARGET_XXX">FT_LOAD_TARGET_MONO</a> enforces a lot of recomputation for TrueType fonts, which is slow. Another reason is caching: Selecting a different mode usually causes changes in both the outlines and the rasterized bitmaps; it is thus necessary to empty the cache after a mode switch to avoid false hits.</p>

This means that if no font driver is capable of handling the raw compressed file, the library will try to open a bzip2 compressed stream from it and re-open the face with it.</p>

+
+<p>This section describes the FreeType&nbsp;2 cache sub-system, which is used to limit the number of concurrently opened <a href="ft2-base_interface.html#FT_Face">FT_Face</a> and <a href="ft2-base_interface.html#FT_Size">FT_Size</a> objects, as well as caching information like character maps and glyph images while limiting their maximum memory usage.</p>
+<p>Note that all types and functions begin with the &lsquo;FTC_&rsquo; prefix.</p>
+<p>The cache is highly portable and thus doesn't know anything about the fonts installed on your system, or how to access them. This implies the following scheme:</p>
+<p>First, available or installed font faces are uniquely identified by <a href="ft2-cache_subsystem.html#FTC_FaceID">FTC_FaceID</a> values, provided to the cache by the client. Note that the cache only stores and compares these values, and doesn't try to interpret them in any way.</p>
+<p>Second, the cache calls, only when needed, a client-provided function to convert an <a href="ft2-cache_subsystem.html#FTC_FaceID">FTC_FaceID</a> into a new <a href="ft2-base_interface.html#FT_Face">FT_Face</a> object. The latter is then completely managed by the cache, including its termination through <a href="ft2-base_interface.html#FT_Done_Face">FT_Done_Face</a>. To monitor termination of face objects, the finalizer callback in the &lsquo;generic&rsquo; field of the <a href="ft2-base_interface.html#FT_Face">FT_Face</a> object can be used, which might also be used to store the <a href="ft2-cache_subsystem.html#FTC_FaceID">FTC_FaceID</a> of the face.</p>
+<p>Clients are free to map face IDs to anything else. The most simple usage is to associate them to a (pathname,face_index) pair that is used to call <a href="ft2-base_interface.html#FT_New_Face">FT_New_Face</a>. However, more complex schemes are also possible.</p>
+<p>Note that for the cache to work correctly, the face ID values must be <b>persistent</b>, which means that the contents they point to should not change at runtime, or that their value should not become invalid.</p>
+<p>If this is unavoidable (e.g., when a font is uninstalled at runtime), you should call <a href="ft2-cache_subsystem.html#FTC_Manager_RemoveFaceID">FTC_Manager_RemoveFaceID</a> as soon as possible, to let the cache get rid of any references to the old <a href="ft2-cache_subsystem.html#FTC_FaceID">FTC_FaceID</a> it may keep internally. Failure to do so will lead to incorrect behaviour or even crashes.</p>
+<p>To use the cache, start with calling <a href="ft2-cache_subsystem.html#FTC_Manager_New">FTC_Manager_New</a> to create a new <a href="ft2-cache_subsystem.html#FTC_Manager">FTC_Manager</a> object, which models a single cache instance. You can then look up <a href="ft2-base_interface.html#FT_Face">FT_Face</a> and <a href="ft2-base_interface.html#FT_Size">FT_Size</a> objects with <a href="ft2-cache_subsystem.html#FTC_Manager_LookupFace">FTC_Manager_LookupFace</a> and <a href="ft2-cache_subsystem.html#FTC_Manager_LookupSize">FTC_Manager_LookupSize</a>, respectively.</p>
+<p>If you want to use the charmap caching, call <a href="ft2-cache_subsystem.html#FTC_CMapCache_New">FTC_CMapCache_New</a>, then later use <a href="ft2-cache_subsystem.html#FTC_CMapCache_Lookup">FTC_CMapCache_Lookup</a> to perform the equivalent of <a href="ft2-base_interface.html#FT_Get_Char_Index">FT_Get_Char_Index</a>, only much faster.</p>
+<p>If you want to use the <a href="ft2-glyph_management.html#FT_Glyph">FT_Glyph</a> caching, call <a href="ft2-cache_subsystem.html#FTC_ImageCache">FTC_ImageCache</a>, then later use <a href="ft2-cache_subsystem.html#FTC_ImageCache_Lookup">FTC_ImageCache_Lookup</a> to retrieve the corresponding <a href="ft2-glyph_management.html#FT_Glyph">FT_Glyph</a> objects from the cache.</p>
+<p>If you need lots of small bitmaps, it is much more memory efficient to call <a href="ft2-cache_subsystem.html#FTC_SBitCache_New">FTC_SBitCache_New</a> followed by <a href="ft2-cache_subsystem.html#FTC_SBitCache_Lookup">FTC_SBitCache_Lookup</a>. This returns <a href="ft2-cache_subsystem.html#FTC_SBitRec">FTC_SBitRec</a> structures, which are used to store small bitmaps directly. (A small bitmap is one whose metrics and dimensions all fit into 8-bit integers).</p>
+<p>We hope to also provide a kerning cache in the near future.</p>

+<p>The manager intentionally limits the total number of opened <a href="ft2-base_interface.html#FT_Face">FT_Face</a> and <a href="ft2-base_interface.html#FT_Size">FT_Size</a> objects to control memory usage.

+<p>The descriptor's &lsquo;buffer&rsquo; field is set to&nbsp;0 to indicate a missing glyph bitmap.</p>
+<p>If &lsquo;anode&rsquo; is <i>not</i> NULL, it receives the address of the cache node containing the bitmap, after increasing its reference count.

+<p>If &lsquo;anode&rsquo; is NULL, the cache node is left unchanged, which means that the bitmap could be flushed out of the cache on the next call to one of the caching sub-system APIs. Don't assume that it is persistent!</p>

This ensures that the node (as well as the image) will always be kept in the cache until you call <a href="ft2-cache_subsystem.html#FTC_Node_Unref">FTC_Node_Unref</a> to &lsquo;release&rsquo; it.</p>
+<p>If &lsquo;anode&rsquo; is NULL, the cache node is left unchanged, which means that the bitmap could be flushed out of the cache on the next call to one of the caching sub-system APIs. Don't assume that it is persistent!</p>

+<h1>FreeType-2.9.1 API Reference</h1>
+
+<h1 id="cff_driver">The CFF driver</h1>
+
+<p>While FreeType's CFF driver doesn't expose API functions by itself, it is possible to control its behaviour with <a href="ft2-module_management.html#FT_Property_Set">FT_Property_Set</a> and <a href="ft2-module_management.html#FT_Property_Get">FT_Property_Get</a>.</p>
+<p>The CFF driver's module name is &lsquo;cff&rsquo;.</p>
+<p>Available properties are <a href="ft2-properties.html#hinting-engine">hinting-engine</a>, <a href="ft2-properties.html#no-stem-darkening">no-stem-darkening</a>, <a href="ft2-properties.html#darkening-parameters">darkening-parameters</a>, and <a href="ft2-properties.html#random-seed">random-seed</a>, as documented in the &lsquo;<a href="ft2-properties.html#properties">Driver properties</a>&rsquo; section.</p>
+<p><b>Hinting</b> <b>and</b> <b>antialiasing</b> <b>principles</b> <b>of</b> <b>the</b> <b>new</b> <b>engine</b></p>
+<p>The rasterizer is positioning horizontal features (e.g., ascender height &amp; x-height, or crossbars) on the pixel grid and minimizing the amount of antialiasing applied to them, while placing vertical features (vertical stems) on the pixel grid without hinting, thus representing the stem position and weight accurately. Sometimes the vertical stems may be only partially black. In this context, &lsquo;antialiasing&rsquo; means that stems are not positioned exactly on pixel borders, causing a fuzzy appearance.</p>
+<p>There are two principles behind this approach.</p>
+<p>1) No hinting in the horizontal direction: Unlike &lsquo;superhinted&rsquo; TrueType, which changes glyph widths to accommodate regular inter-glyph spacing, Adobe's approach is &lsquo;faithful to the design&rsquo; in representing both the glyph width and the inter-glyph spacing designed for the font. This makes the screen display as close as it can be to the result one would get with infinite resolution, while preserving what is considered the key characteristics of each glyph. Note that the distances between unhinted and grid-fitted positions at small sizes are comparable to kerning values and thus would be noticeable (and distracting) while reading if hinting were applied.</p>
+<p>One of the reasons to not hint horizontally is antialiasing for LCD screens: The pixel geometry of modern displays supplies three vertical subpixels as the eye moves horizontally across each visible pixel. On devices where we can be certain this characteristic is present a rasterizer can take advantage of the subpixels to add increments of weight. In Western writing systems this turns out to be the more critical direction anyway; the weights and spacing of vertical stems (see above) are central to Armenian, Cyrillic, Greek, and Latin type designs. Even when the rasterizer uses greyscale antialiasing instead of color (a necessary compromise when one doesn't know the screen characteristics), the unhinted vertical features preserve the design's weight and spacing much better than aliased type would.</p>
+<p>2) Alignment in the vertical direction: Weights and spacing along the y&nbsp;axis are less critical; what is much more important is the visual alignment of related features (like cap-height and x-height). The sense of alignment for these is enhanced by the sharpness of grid-fit edges, while the cruder vertical resolution (full pixels instead of 1/3 pixels) is less of a problem.</p>
+<p>On the technical side, horizontal alignment zones for ascender, x-height, and other important height values (traditionally called &lsquo;blue zones&rsquo;) as defined in the font are positioned independently, each being rounded to the nearest pixel edge, taking care of overshoot suppression at small sizes, stem darkening, and scaling.</p>
+<p>Hstems (this is, hint values defined in the font to help align horizontal features) that fall within a blue zone are said to be &lsquo;captured&rsquo; and are aligned to that zone. Uncaptured stems are moved in one of four ways, top edge up or down, bottom edge up or down. Unless there are conflicting hstems, the smallest movement is taken to minimize distortion.</p>

+<p>This function has been optimized for the case where the absolute value of &lsquo;a&rsquo; is less than 2048, and &lsquo;b&rsquo; is a 16.16 scaling factor. As this happens mainly when scaling from notional units to fractional pixels in FreeType, it resulted in noticeable speed improvements between versions 2.x and 1.x.</p>
+<p>As a conclusion, always try to place a 16.16 factor as the <i>second</i> argument of this function; this can make a great difference.</p>

+<p>The list below is taken verbatim from the file &lsquo;fterrdef.h&rsquo; (loaded automatically by including &lsquo;FT_FREETYPE_H&rsquo;). The first argument of the &lsquo;FT_ERROR_DEF_&rsquo; macro is the error label; by default, the prefix &lsquo;FT_Err_&rsquo; gets added so that you get error names like &lsquo;FT_Err_Cannot_Open_Resource&rsquo;. The second argument is the error code, and the last argument an error string, which is not used by FreeType.</p>
+<p>Within your application you should <b>only</b> use error names and <b>never</b> its numeric values! The latter might (and actually do) change in forthcoming FreeType versions.</p>
+<p>Macro &lsquo;FT_NOERRORDEF_&rsquo; defines &lsquo;FT_Err_Ok&rsquo;, which is always zero. See the &lsquo;Error Enumerations&rsquo; subsection how to automatically generate a list of error strings.</p>

+<h1>FreeType-2.9.1 API Reference</h1>
+
+<h1 id="error_enumerations">Error Enumerations</h1>
+
+<p>The header file &lsquo;fterrors.h&rsquo; (which is automatically included by &lsquo;freetype.h&rsquo; defines the handling of FreeType's enumeration constants. It can also be used to generate error message strings with a small macro trick explained below.</p>
+<p><b>Error</b> <b>Formats</b></p>
+<p>The configuration macro FT_CONFIG_OPTION_USE_MODULE_ERRORS can be defined in &lsquo;ftoption.h&rsquo; in order to make the higher byte indicate the module where the error has happened (this is not compatible with standard builds of FreeType&nbsp;2, however). See the file &lsquo;ftmoderr.h&rsquo; for more details.</p>
+<p><b>Error</b> <b>Message</b> <b>Strings</b></p>
+<p>Error definitions are set up with special macros that allow client applications to build a table of error message strings. The strings are not included in a normal build of FreeType&nbsp;2 to save space (most client applications do not use them).</p>
+<p>To do so, you have to define the following macros before including this file.</p>
+<pre class="colored">
+  FT_ERROR_START_LIST
+</pre>
+<p>This macro is called before anything else to define the start of the error list. It is followed by several FT_ERROR_DEF calls.</p>
+<pre class="colored">
+  FT_ERROR_DEF( e, v, s )
+</pre>
+<p>This macro is called to define one single error. &lsquo;e&rsquo; is the error code identifier (e.g., &lsquo;Invalid_Argument&rsquo;), &lsquo;v&rsquo; is the error's numerical value, and &lsquo;s&rsquo; is the corresponding error string.</p>
+<pre class="colored">
+  FT_ERROR_END_LIST
+</pre>
+<p>This macro ends the list.</p>
+<p>Additionally, you have to undefine &lsquo;FTERRORS_H_&rsquo; before #including this file.</p>
+<p>Here is a simple example.</p>
+<pre class="colored">
+  #undef FTERRORS_H_
+  #define FT_ERRORDEF( e, v, s )  { e, s },
+  #define FT_ERROR_START_LIST     {
+  #define FT_ERROR_END_LIST       { 0, NULL } };
+
+  const struct
+  {
+    int          err_code;
+    const char*  err_msg;
+  } ft_errors[] =
+
+  #include FT_ERRORS_H
+</pre>
+<p>Note that &lsquo;FT_Err_Ok&rsquo; is <i>not</i> defined with &lsquo;FT_ERRORDEF&rsquo; but with &lsquo;FT_NOERRORDEF&rsquo;; it is always zero.</p>

+<p>If the glyph has been loaded with <a href="ft2-base_interface.html#FT_LOAD_XXX">FT_LOAD_NO_SCALE</a>, &lsquo;bbox_mode&rsquo; must be set to <a href="ft2-glyph_management.html#FT_Glyph_BBox_Mode">FT_GLYPH_BBOX_UNSCALED</a> to get unscaled font units in 26.6 pixel format. The value <a href="ft2-glyph_management.html#FT_Glyph_BBox_Mode">FT_GLYPH_BBOX_SUBPIXELS</a> is another name for this constant.</p>
+<p>If the font is tricky and the glyph has been loaded with <a href="ft2-base_interface.html#FT_LOAD_XXX">FT_LOAD_NO_SCALE</a>, the resulting CBox is meaningless. To get reasonable values for the CBox it is necessary to load the glyph at a large ppem value (so that the hinting instructions can properly shift and scale the subglyphs), then extracting the CBox, which can be eventually converted back to font units.</p>
+<p>Note that the maximum coordinates are exclusive, which means that one can compute the width and height of the glyph image (be it in integer or 26.6 pixels) as:</p>
+<pre class="colored">
+  width  = bbox.xMax - bbox.xMin;
+  height = bbox.yMax - bbox.yMin;
+</pre>
+<p>Note also that for 26.6 coordinates, if &lsquo;bbox_mode&rsquo; is set to <a href="ft2-glyph_management.html#FT_Glyph_BBox_Mode">FT_GLYPH_BBOX_GRIDFIT</a>, the coordinates will also be grid-fitted, which corresponds to:</p>

+  bbox.yMin = FLOOR(bbox.yMin);
+  bbox.xMax = CEILING(bbox.xMax);
+  bbox.yMax = CEILING(bbox.yMax);

+<p>To get the bbox in grid-fitted pixel coordinates, set &lsquo;bbox_mode&rsquo; to <a href="ft2-glyph_management.html#FT_Glyph_BBox_Mode">FT_GLYPH_BBOX_PIXELS</a>.</p>

+<p>Many characters, especially for CJK scripts, have variant forms. They are a sort of grey area somewhere between being totally irrelevant and semantically distinct; for this reason, the Unicode consortium decided to introduce Variation Sequences (VS), consisting of a Unicode base character and a variation selector instead of further extending the already huge number of characters.</p>
+<p>Unicode maintains two different sets, namely &lsquo;Standardized Variation Sequences&rsquo; and registered &lsquo;Ideographic Variation Sequences&rsquo; (IVS), collected in the &lsquo;Ideographic Variation Database&rsquo; (IVD).</p>
+<p><a href="https://unicode.org/Public/UCD/latest/ucd/StandardizedVariants.txt">https://unicode.org/Public/UCD/latest/ucd/StandardizedVariants.txt</a> <a href="https://unicode.org/reports/tr37/">https://unicode.org/reports/tr37/</a> <a href="https://unicode.org/ivd/">https://unicode.org/ivd/</a></p>
+<p>To date (January 2017), the character with the most ideographic variations is U+9089, having 32 such IVS.</p>
+<p>Three Mongolian Variation Selectors have the values U+180B-U+180D; 256 generic Variation Selectors are encoded in the ranges U+FE00-U+FE0F and U+E0100-U+E01EF. IVS currently use Variation Selectors from the range U+E0100-U+E01EF only.</p>
+<p>A VS consists of the base character value followed by a single Variation Selector. For example, to get the first variation of U+9089, you have to write the character sequence &lsquo;U+9089 U+E0100&rsquo;.</p>
+<p>Adobe and MS decided to support both standardized and ideographic VS with a new cmap subtable (format&nbsp;14). It is an odd subtable because it is not a mapping of input code points to glyphs, but contains lists of all variations supported by the font.</p>
+<p>A variation may be either &lsquo;default&rsquo; or &lsquo;non-default&rsquo; for a given font. A default variation is the one you will get for that code point if you look it up in the standard Unicode cmap. A non-default variation is a different glyph.</p>

+<p>The following macros are defined to the name of specific FreeType&nbsp;2 header files. They can be used directly in #include statements as in:</p>
+<pre class="colored">
+  #include FT_FREETYPE_H
+  #include FT_MULTIPLE_MASTERS_H
+  #include FT_GLYPH_H
+</pre>
+<p>There are several reasons why we are now using macros to name public header files. The first one is that such macros are not limited to the infamous 8.3&nbsp;naming rule required by DOS (and &lsquo;FT_MULTIPLE_MASTERS_H&rsquo; is a lot more meaningful than &lsquo;ftmm.h&rsquo;).</p>
+<p>The second reason is that it allows for more flexibility in the way FreeType&nbsp;2 is installed on a given system.</p>

+<h1>FreeType-2.9.1 API Reference</h1>
+
+<h1 id="header_inclusion">FreeType's header inclusion scheme</h1>
+
+<p>To be as flexible as possible (and for historical reasons), FreeType uses a very special inclusion scheme to load header files, for example</p>
+<pre class="colored">
+  #include &lt;ft2build.h&gt;
+
+  #include FT_FREETYPE_H
+  #include FT_OUTLINE_H
+</pre>
+<p>A compiler and its preprocessor only needs an include path to find the file &lsquo;ft2build.h&rsquo;; the exact locations and names of the other FreeType header files are hidden by preprocessor macro names, loaded by &lsquo;ft2build.h&rsquo;. The API documentation always gives the header macro name needed for a particular function.</p>

+<p>This section contains various functions used to perform so-called &lsquo;incremental&rsquo; glyph loading. This is a mode where all glyphs loaded from a given <a href="ft2-base_interface.html#FT_Face">FT_Face</a> are provided by the client application.</p>
+<p>Apart from that, all other tables are loaded normally from the font file. This mode is useful when FreeType is used within another engine, e.g., a PostScript Imaging Processor.</p>
+<p>To enable this mode, you must use <a href="ft2-base_interface.html#FT_Open_Face">FT_Open_Face</a>, passing an <a href="ft2-base_interface.html#FT_Parameter">FT_Parameter</a> with the <a href="ft2-parameter_tags.html#FT_PARAM_TAG_INCREMENTAL">FT_PARAM_TAG_INCREMENTAL</a> tag and an <a href="ft2-incremental.html#FT_Incremental_Interface">FT_Incremental_Interface</a> value.

+<p>Should you #define FT_CONFIG_OPTION_SUBPIXEL_RENDERING in your &lsquo;ftoption.h&rsquo;, which enables patented ClearType-style rendering, the LCD-optimized glyph bitmaps should be filtered to reduce color fringes inherent to this technology. The default FreeType LCD rendering uses different technology, and API described below, although available, does nothing.</p>
+<p>ClearType-style LCD rendering exploits the color-striped structure of LCD pixels, increasing the available resolution in the direction of the stripe (usually horizontal RGB) by a factor of&nbsp;3. Since these subpixels are color pixels, using them unfiltered creates severe color fringes. Use the <a href="ft2-lcd_filtering.html#FT_Library_SetLcdFilter">FT_Library_SetLcdFilter</a> API to specify a low-pass filter, which is then applied to subpixel-rendered bitmaps generated through <a href="ft2-base_interface.html#FT_Render_Glyph">FT_Render_Glyph</a>. The filter sacrifices some of the higher resolution to reduce color fringes, making the glyph image slightly blurrier. Positional improvements will remain.</p>
+<p>A filter should have two properties:</p>
+<p>1) It should be normalized, meaning the sum of the 5&nbsp;components should be 256 (0x100). It is possible to go above or under this target sum, however: going under means tossing out contrast, going over means invoking clamping and thereby non-linearities that increase contrast somewhat at the expense of greater distortion and color-fringing. Contrast is better enhanced through stem darkening.</p>
+<p>2) It should be color-balanced, meaning a filter &lsquo;{&nbsp;a, b, c, b, a&nbsp;}&rsquo; where a&nbsp;+ b&nbsp;=&nbsp;c. It distributes the computed coverage for one subpixel to all subpixels equally, sacrificing some won resolution but drastically reducing color-fringing. Positioning improvements remain! Note that color-fringing can only really be minimized when using a color-balanced filter and alpha-blending the glyph onto a surface in linear space; see <a href="ft2-base_interface.html#FT_Render_Glyph">FT_Render_Glyph</a>.</p>
+<p>Regarding the form, a filter can be a &lsquo;boxy&rsquo; filter or a &lsquo;beveled&rsquo; filter. Boxy filters are sharper but are less forgiving of non-ideal gamma curves of a screen (viewing angles!), beveled filters are fuzzier but more tolerant.</p>
+<p>Examples:</p>
+<p>- [0x10 0x40 0x70 0x40 0x10] is beveled and neither balanced nor normalized.</p>
+<p>- [0x1A 0x33 0x4D 0x33 0x1A] is beveled and balanced but not normalized.</p>
+<p>- [0x19 0x33 0x66 0x4c 0x19] is beveled and normalized but not balanced.</p>
+<p>- [0x00 0x4c 0x66 0x4c 0x00] is boxily beveled and normalized but not balanced.</p>
+<p>- [0x00 0x55 0x56 0x55 0x00] is boxy, normalized, and almost balanced.</p>
+<p>- [0x08 0x4D 0x56 0x4D 0x08] is beveled, normalized and, almost balanced.</p>
+<p>The filter affects glyph bitmaps rendered through <a href="ft2-base_interface.html#FT_Render_Glyph">FT_Render_Glyph</a>, <a href="ft2-base_interface.html#FT_Load_Glyph">FT_Load_Glyph</a>, and <a href="ft2-base_interface.html#FT_Load_Char">FT_Load_Char</a>. It does <i>not</i> affect the output of <a href="ft2-outline_processing.html#FT_Outline_Render">FT_Outline_Render</a> and <a href="ft2-outline_processing.html#FT_Outline_Get_Bitmap">FT_Outline_Get_Bitmap</a>.</p>
+<p>If this feature is activated, the dimensions of LCD glyph bitmaps are either wider or taller than the dimensions of the corresponding outline with regard to the pixel grid. For example, for <a href="ft2-base_interface.html#FT_Render_Mode">FT_RENDER_MODE_LCD</a>, the filter adds 3&nbsp;subpixels to the left, and 3&nbsp;subpixels to the right. The bitmap offset values are adjusted accordingly, so clients shouldn't need to modify their layout and glyph positioning code when enabling the filter.</p>
+<p>It is important to understand that linear alpha blending and gamma correction is critical for correctly rendering glyphs onto surfaces without artifacts and even more critical when subpixel rendering is involved.</p>
+<p>Each of the 3&nbsp;alpha values (subpixels) is independently used to blend one color channel. That is, red alpha blends the red channel of the text color with the red channel of the background pixel. The distribution of density values by the color-balanced filter assumes alpha blending is done in linear space; only then color artifacts cancel out.</p>

+<p>FreeType error code. 0&nbsp;means success.</p>
+
+<h4>note</h4>
+<p>The source stream must be opened <i>before</i> calling this function.</p>
+<p>Calling the internal function &lsquo;FT_Stream_Close&rsquo; on the new stream will <b>not</b> call &lsquo;FT_Stream_Close&rsquo; on the source stream. None of the stream objects will be released to the heap.</p>
+<p>The stream implementation is very basic and resets the decompression process each time seeking backwards is needed within the stream</p>
+<p>In certain builds of the library, LZW compression recognition is automatically handled when calling <a href="ft2-base_interface.html#FT_New_Face">FT_New_Face</a> or <a href="ft2-base_interface.html#FT_Open_Face">FT_Open_Face</a>. This means that if no font driver is capable of handling the raw compressed file, the library will try to open a LZW stream from it and re-open the face with it.</p>
+<p>This function may return &lsquo;FT_Err_Unimplemented_Feature&rsquo; if your build of FreeType was not compiled with LZW support.</p>

+<p>Thanks to Adobe, which contributed a new hinting (and parsing) engine, an application can select between &lsquo;freetype&rsquo; and &lsquo;adobe&rsquo; if compiled with CFF_CONFIG_OPTION_OLD_ENGINE. If this configuration macro isn't defined, &lsquo;hinting-engine&rsquo; does nothing.</p>

+<p>All glyphs that pass through the auto-hinter will be emboldened unless this property is set to TRUE. The same is true for the CFF, Type&nbsp;1, and CID font modules if the &lsquo;Adobe&rsquo; engine is selected (which is the default).</p>
+<p>Stem darkening emboldens glyphs at smaller sizes to make them more readable on common low-DPI screens when using linear alpha blending and gamma correction, see <a href="ft2-base_interface.html#FT_Render_Glyph">FT_Render_Glyph</a>. When not using linear alpha blending and gamma correction, glyphs will appear heavy and fuzzy!</p>
+<p>Gamma correction essentially lightens fonts since shades of grey are shifted to higher pixel values (=&nbsp;higher brightness) to match the original intention to the reality of our screens. The side-effect is that glyphs &lsquo;thin out&rsquo;. Mac OS&nbsp;X and Adobe's proprietary font rendering library implement a counter-measure: stem darkening at smaller sizes where shades of gray dominate. By emboldening a glyph slightly in relation to its pixel size, individual pixels get higher coverage of filled-in outlines and are therefore &lsquo;blacker&rsquo;. This counteracts the &lsquo;thinning out&rsquo; of glyphs, making text remain readable at smaller sizes.</p>
+<p>By default, the Adobe engines for CFF, Type&nbsp;1, and CID fonts darken stems at smaller sizes, regardless of hinting, to enhance contrast. Setting this property, stem darkening gets switched off.</p>
+<p>For the auto-hinter, stem-darkening is experimental currently and thus switched off by default (this is, &lsquo;no-stem-darkening&rsquo; is set to TRUE by default). Total consistency with the CFF driver is not achieved right now because the emboldening method differs and glyphs must be scaled down on the Y-axis to keep outline points inside their precomputed blue zones. The smaller the size (especially 9ppem and down), the higher the loss of emboldening versus the CFF driver.</p>
+<p>Note that stem darkening is never applied if <a href="ft2-base_interface.html#FT_LOAD_XXX">FT_LOAD_NO_SCALE</a> is set.</p>

Its argument is a signed 32bit integer; if the value is zero or negative, the seed given by the &lsquo;intitialRandomSeed&rsquo; private DICT operator in a CFF file gets used (or a default value if there is no such operator). If the value is positive, use it instead of &lsquo;initialRandomSeed&rsquo;, which is consequently ignored.</p>

+<p>The &lsquo;version&rsquo; field gives a rough orientation only, since some applications provided certain features much earlier (as an example, Microsoft Reader used subpixel and Y-direction ClearType already in Windows 2000). Similarly, updates to a given framework might include improved hinting support.</p>

+<p>Color and Gray ClearType are the two available variants of &lsquo;Y-direction ClearType&rsquo;, meaning grayscale rasterization along the Y-direction; the name used in the TrueType specification for this feature is &lsquo;symmetric smoothing&rsquo;. &lsquo;Classic ClearType&rsquo; is the original algorithm used before introducing a modified version in Win&nbsp;XP. Another name for v1.6's grayscale rendering is &lsquo;font smoothing&rsquo;, and &lsquo;Color ClearType&rsquo; is sometimes also called &lsquo;DWrite ClearType&rsquo;. To differentiate between today's Color ClearType and the earlier ClearType variant with B/W rendering along the vertical axis, the latter is sometimes called &lsquo;GDI ClearType&rsquo;.</p>
+<p>&lsquo;Normal&rsquo; and &lsquo;high&rsquo; sampling describe the (virtual) resolution to access the rasterized outline after the hinting process. &lsquo;Normal&rsquo; means 1 sample per grid line (i.e., B/W). In the current Microsoft implementation, &lsquo;high&rsquo; means an extra virtual resolution of 16x16 (or 16x1) grid lines per pixel for bytecode instructions like &lsquo;MIRP&rsquo;. After hinting, these 16 grid lines are mapped to 6x5 (or 6x1) grid lines for color filtering if Color ClearType is activated.</p>
+<p>Note that &lsquo;Gray ClearType&rsquo; is essentially the same as v1.6's grayscale rendering. However, the GETINFO instruction handles it differently: v1.6 returns bit&nbsp;12 (hinting for grayscale), while v2.1 returns bits&nbsp;13 (hinting for ClearType), 18 (symmetrical smoothing), and&nbsp;19 (Gray ClearType). Also, this mode respects bits 2 and&nbsp;3 for the version&nbsp;1 gasp table exclusively (like Color ClearType), while v1.6 only respects the values of version&nbsp;0 (bits 0 and&nbsp;1).</p>
+<p>Keep in mind that the features of the above interpreter versions might not map exactly to FreeType features or behavior because it is a fundamentally different library with different internals.</p>

+
+<p>Currently, three versions are available, two representing the bytecode interpreter with subpixel hinting support (old &lsquo;Infinality&rsquo; code and new stripped-down and higher performance &lsquo;minimal&rsquo; code) and one without, respectively. The default is subpixel support if TT_CONFIG_OPTION_SUBPIXEL_HINTING is defined, and no subpixel support otherwise (since it isn't available then).</p>
+<p>If subpixel hinting is on, many TrueType bytecode instructions behave differently compared to B/W or grayscale rendering (except if &lsquo;native ClearType&rsquo; is selected by the font). Microsoft's main idea is to render at a much increased horizontal resolution, then sampling down the created output to subpixel precision. However, many older fonts are not suited to this and must be specially taken care of by applying (hardcoded) tweaks in Microsoft's interpreter.</p>
+<p>Details on subpixel hinting and some of the necessary tweaks can be found in Greg Hitchcock's whitepaper at &lsquo;<a href="https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx">https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx</a>&rsquo;. Note that FreeType currently doesn't really &lsquo;subpixel hint&rsquo; (6x1, 6x2, or 6x5 supersampling) like discussed in the paper. Depending on the chosen interpreter, it simply ignores instructions on vertical stems to arrive at very similar results.</p>

+<p>The auto-hinter provides various script modules to hint glyphs. Examples of supported scripts are Latin or CJK. Before a glyph is auto-hinted, the Unicode character map of the font gets examined, and the script is then determined based on Unicode character ranges, see below.</p>
+<p>OpenType fonts, however, often provide much more glyphs than character codes (small caps, superscripts, ligatures, swashes, etc.), to be controlled by so-called &lsquo;features&rsquo;. Handling OpenType features can be quite complicated and thus needs a separate library on top of FreeType.</p>
+<p>The mapping between glyph indices and scripts (in the auto-hinter sense, see the <a href="ft2-properties.html#FT_AUTOHINTER_SCRIPT_XXX">FT_AUTOHINTER_SCRIPT_XXX</a> values) is stored as an array with &lsquo;num_glyphs&rsquo; elements, as found in the font's <a href="ft2-base_interface.html#FT_Face">FT_Face</a> structure. The &lsquo;glyph-to-script-map&rsquo; property returns a pointer to this array, which can be modified as needed. Note that the modification should happen before the first glyph gets processed by the auto-hinter so that the global analysis of the font shapes actually uses the modified mapping.</p>

+
+<p><b>Experimental</b> <b>only</b></p>
+<p>If FreeType gets compiled with option AF_CONFIG_OPTION_USE_WARPER to activate the warp hinting code in the auto-hinter, this property switches warping on and off.</p>
+<p>Warping only works in &lsquo;normal&rsquo; auto-hinting mode replacing it. The idea of the code is to slightly scale and shift a glyph along the non-hinted dimension (which is usually the horizontal axis) so that as much of its segments are aligned (more or less) to the grid. To find out a glyph's optimal scaling and shifting value, various parameter combinations are tried and scored.</p>
+<p>By default, warping is off. The example below shows how to switch on warping (omitting the error handling).</p>
+<pre class="colored">
+  FT_Library  library;
+  FT_Bool     warping = 1;
+
+
+  FT_Init_FreeType( &amp;library );
+
+  FT_Property_Set( library, "autofitter",
+                            "warping", &amp;warping );
+</pre>
+
+<h4>note</h4>
+<p>This property can be used with <a href="ft2-module_management.html#FT_Property_Get">FT_Property_Get</a> also.</p>
+<p>This property can be set via the &lsquo;FREETYPE_PROPERTIES&rsquo; environment variable (using values 1 and 0 for &lsquo;on&rsquo; and &lsquo;off&rsquo;, respectively).</p>
+<p>The warping code can also change advance widths. Have a look at the &lsquo;lsb_delta&rsquo; and &lsquo;rsb_delta&rsquo; fields in the <a href="ft2-base_interface.html#FT_GlyphSlotRec">FT_GlyphSlotRec</a> structure for details on improving inter-glyph distances while rendering.</p>
+<p>Since warping is a global property of the auto-hinter it is best to change its value before rendering any face. Otherwise, you should reload all faces that get auto-hinted in &lsquo;normal&rsquo; hinting mode.</p>

+<p>It is however possible to create more sizes for a given face, mostly in order to manage several character pixel sizes of the same font family and style. See <a href="ft2-sizes_management.html#FT_New_Size">FT_New_Size</a> and <a href="ft2-sizes_management.html#FT_Done_Size">FT_Done_Size</a>.</p>

+<h1>FreeType-2.9.1 API Reference</h1>
+
+<h1 id="t1_cid_driver">The Type 1 and CID drivers</h1>
+
+<p>It is possible to control the behaviour of FreeType's Type&nbsp;1 and Type&nbsp;1 CID drivers with <a href="ft2-module_management.html#FT_Property_Set">FT_Property_Set</a> and <a href="ft2-module_management.html#FT_Property_Get">FT_Property_Get</a>.</p>
+<p>Behind the scenes, both drivers use the Adobe CFF engine for hinting; however, the used properties must be specified separately.</p>
+<p>The Type&nbsp;1 driver's module name is &lsquo;type1&rsquo;; the CID driver's module name is &lsquo;t1cid&rsquo;.</p>
+<p>Available properties are <a href="ft2-properties.html#hinting-engine">hinting-engine</a>, <a href="ft2-properties.html#no-stem-darkening">no-stem-darkening</a>, <a href="ft2-properties.html#darkening-parameters">darkening-parameters</a>, and <a href="ft2-properties.html#random-seed">random-seed</a>, as documented in the &lsquo;<a href="ft2-properties.html#properties">Driver properties</a>&rsquo; section.</p>
+<p>Please see the &lsquo;<a href="ft2-cff_driver.html#cff_driver">The CFF driver</a>&rsquo; section for more details on the new hinting engine.</p>

+<h1>FreeType-2.9.1 API Reference</h1>
+
+<h1 id="tt_driver">The TrueType driver</h1>
+
+<p>While FreeType's TrueType driver doesn't expose API functions by itself, it is possible to control its behaviour with <a href="ft2-module_management.html#FT_Property_Set">FT_Property_Set</a> and <a href="ft2-module_management.html#FT_Property_Get">FT_Property_Get</a>. The following lists the available properties together with the necessary macros and structures.</p>
+<p>The TrueType driver's module name is &lsquo;truetype&rsquo;.</p>
+<p>A single property <a href="ft2-properties.html#interpreter-version">interpreter-version</a> is available, as documented in the &lsquo;<a href="ft2-properties.html#properties">Driver properties</a>&rsquo; section.</p>
+<p>We start with a list of definitions, kindly provided by Greg Hitchcock.</p>
+<p><i>Bi-Level</i> <i>Rendering</i></p>
+<p>Monochromatic rendering, exclusively used in the early days of TrueType by both Apple and Microsoft. Microsoft's GDI interface supported hinting of the right-side bearing point, such that the advance width could be non-linear. Most often this was done to achieve some level of glyph symmetry. To enable reasonable performance (e.g., not having to run hinting on all glyphs just to get the widths) there was a bit in the head table indicating if the side bearing was hinted, and additional tables, &lsquo;hdmx&rsquo; and &lsquo;LTSH&rsquo;, to cache hinting widths across multiple sizes and device aspect ratios.</p>
+<p><i>Font</i> <i>Smoothing</i></p>
+<p>Microsoft's GDI implementation of anti-aliasing. Not traditional anti-aliasing as the outlines were hinted before the sampling. The widths matched the bi-level rendering.</p>
+<p><i>ClearType</i> <i>Rendering</i></p>
+<p>Technique that uses physical subpixels to improve rendering on LCD (and other) displays. Because of the higher resolution, many methods of improving symmetry in glyphs through hinting the right-side bearing were no longer necessary. This lead to what GDI calls &lsquo;natural widths&rsquo; ClearType, see <a href="http://www.beatstamm.com/typography/RTRCh4.htm#Sec21">http://www.beatstamm.com/typography/RTRCh4.htm#Sec21</a>. Since hinting has extra resolution, most non-linearity went away, but it is still possible for hints to change the advance widths in this mode.</p>
+<p><i>ClearType</i> <i>Compatible</i> <i>Widths</i></p>
+<p>One of the earliest challenges with ClearType was allowing the implementation in GDI to be selected without requiring all UI and documents to reflow. To address this, a compatible method of rendering ClearType was added where the font hints are executed once to determine the width in bi-level rendering, and then re-run in ClearType, with the difference in widths being absorbed in the font hints for ClearType (mostly in the white space of hints); see <a href="http://www.beatstamm.com/typography/RTRCh4.htm#Sec20">http://www.beatstamm.com/typography/RTRCh4.htm#Sec20</a>. Somewhat by definition, compatible width ClearType allows for non-linear widths, but only when the bi-level version has non-linear widths.</p>
+<p><i>ClearType</i> <i>Subpixel</i> <i>Positioning</i></p>
+<p>One of the nice benefits of ClearType is the ability to more crisply display fractional widths; unfortunately, the GDI model of integer bitmaps did not support this. However, the WPF and Direct Write frameworks do support fractional widths. DWrite calls this &lsquo;natural mode&rsquo;, not to be confused with GDI's &lsquo;natural widths&rsquo;. Subpixel positioning, in the current implementation of Direct Write, unfortunately does not support hinted advance widths, see <a href="http://www.beatstamm.com/typography/RTRCh4.htm#Sec22">http://www.beatstamm.com/typography/RTRCh4.htm#Sec22</a>. Note that the TrueType interpreter fully allows the advance width to be adjusted in this mode, just the DWrite client will ignore those changes.</p>
+<p><i>ClearType</i> <i>Backward</i> <i>Compatibility</i></p>
+<p>This is a set of exceptions made in the TrueType interpreter to minimize hinting techniques that were problematic with the extra resolution of ClearType; see <a href="http://www.beatstamm.com/typography/RTRCh4.htm#Sec1">http://www.beatstamm.com/typography/RTRCh4.htm#Sec1</a> and <a href="https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx">https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx</a>. This technique is not to be confused with ClearType compatible widths. ClearType backward compatibility has no direct impact on changing advance widths, but there might be an indirect impact on disabling some deltas. This could be worked around in backward compatibility mode.</p>
+<p><i>Native</i> <i>ClearType</i> <i>Mode</i></p>
+<p>(Not to be confused with &lsquo;natural widths&rsquo;.) This mode removes all the exceptions in the TrueType interpreter when running with ClearType. Any issues on widths would still apply, though.</p>

+<h4>return</h4>
+<p>The amount of memory (in bytes) required to hold the requested value (if it exists, -1 otherwise).</p>
+
+<h4>note</h4>
+<p>The values returned are not pointers into the internal structures of the face, but are &lsquo;fresh&rsquo; copies, so that the memory containing them belongs to the calling application. This also enforces the &lsquo;read-only&rsquo; nature of these values, i.e., this function cannot be used to manipulate the face.</p>
+<p>&lsquo;value&rsquo; is a void pointer because the values returned can be of various types.</p>
+<p>If either &lsquo;value&rsquo; is NULL or &lsquo;value_len&rsquo; is too small, just the required memory size for the requested entry is returned.</p>
+<p>The &lsquo;idx&rsquo; parameter is used, not only to retrieve elements of, for example, the FontMatrix or FontBBox, but also to retrieve name keys from the CharStrings dictionary, and the charstrings themselves. It is ignored for atomic values.</p>
+<p>PS_DICT_BLUE_SCALE returns a value that is scaled up by 1000. To get the value as in the font stream, you need to divide by 65536000.0 (to remove the FT_Fixed scale, and the x1000 scale).</p>
+<p>IMPORTANT: Only key/value pairs read by the FreeType interpreter can be retrieved. So, for example, PostScript procedures such as NP, ND, and RD are not available. Arbitrary keys are, obviously, not be available either.</p>
+<p>If the font's format is not PostScript-based, this function returns the &lsquo;FT_Err_Invalid_Argument&rsquo; error code.</p>

+How to prepare a new release
+----------------------------
+
+. include/freetype/freetype.h:  Update FREETYPE_MAJOR, FREETYPE_MINOR,
+  and FREETYPE_PATCH.
+
+. Update version numbers in all files where necessary (for example, do
+  a grep for both `2.3.1' and `231' for release 2.3.1).
+
+. builds/unix/configure.raw: Update `version_info'.
+
+. docs/CHANGES: Document differences to last release.
+
+. README: Update.
+
+. docs/VERSIONS.TXT: Document changed `version_info'.
+
+. ChangeLog:   Announce  new  release   (both  in  the  freetype2  and
+  freetype2-demos modules).
+
+. Clone the git archive to another directory with
+
+    git clone -l -s . ../freetype2.test
+
+  or something like this and run
+
+    make distclean; make devel; make
+    make distclean; make devel; make multi
+    make distclean; make devel CC=g++; make CC=g++
+    make distclean; make devel CC=g++; make multi CC=g++
+
+    sh autogen.sh
+    make distclean; ./configure; make
+    make distclean; ./configure CC=g++; make
+
+  in the cloned repository to test compilation with both gcc and g++.
+
+. Test C++ compilation  for freetype2-demos too  (using `git clone' as
+  above).
+
+. Run  src/tools/chktrcmp.py  and check  that there  are no  undefined
+  trace_XXXX macros.
+
+. After pushing the new release,  tag the git repositories (freetype2,
+  freetype2-demos) with
+
+    git tag VER-<version> -m "" -u <committer>
+
+  and push the tags with
+
+    git push --tags
+
+. Check with
+
+    git clean -ndx
+
+  that the git directory is really clean  (and remove extraneous files
+  if necessary).
+
+. Say `make  dist' in both the  freetype2 and freetype2-demos  modules
+  to generate the .tar.gz, .tar.bz2, and .zip files.
+
+. Create     the     doc    bundles    (freetype-doc-<version>.tar.gz,
+  freetype-doc-<version>.tar.bz2,    ftdoc<version>.zip).    This   is
+  everything in
+
+    <freetype-web git repository>/freetype2/docs
+
+  except the `reference' subdirectory.   Do *not* use option `-l' from
+  zip!
+
+. Run the following script (with updated `$VERSION', `$SAVANNAH_USER',
+  and $SOURCEFORGE_USER  variables) to sign and upload the  bundles to
+  both Savannah and SourceForge.  The signing code has been taken from
+  the `gnupload' script (part of the automake bundle).

+   * @enum:
+   *   FT_LOAD_XXX
+   *
+   * @description:
+   *   A list of bit field constants for @FT_Load_Glyph to indicate what
+   *   kind of operations to perform during glyph loading.
+   *
+   * @values:
+   *   FT_LOAD_DEFAULT ::
+   *     Corresponding to~0, this value is used as the default glyph load
+   *     operation.  In this case, the following happens:
+   *
+   *     1. FreeType looks for a bitmap for the glyph corresponding to the
+   *        face's current size.  If one is found, the function returns.
+   *        The bitmap data can be accessed from the glyph slot (see note
+   *        below).
+   *
+   *     2. If no embedded bitmap is searched for or found, FreeType looks
+   *        for a scalable outline.  If one is found, it is loaded from
+   *        the font file, scaled to device pixels, then `hinted' to the
+   *        pixel grid in order to optimize it.  The outline data can be
+   *        accessed from the glyph slot (see note below).
+   *
+   *     Note that by default the glyph loader doesn't render outlines into
+   *     bitmaps.  The following flags are used to modify this default
+   *     behaviour to more specific and useful cases.
+   *
+   *   FT_LOAD_NO_SCALE ::
+   *     Don't scale the loaded outline glyph but keep it in font units.
+   *
+   *     This flag implies @FT_LOAD_NO_HINTING and @FT_LOAD_NO_BITMAP, and
+   *     unsets @FT_LOAD_RENDER.
+   *
+   *     If the font is `tricky' (see @FT_FACE_FLAG_TRICKY for more), using
+   *     FT_LOAD_NO_SCALE usually yields meaningless outlines because the
+   *     subglyphs must be scaled and positioned with hinting instructions.
+   *     This can be solved by loading the font without FT_LOAD_NO_SCALE and
+   *     setting the character size to `font->units_per_EM'.
+   *
+   *   FT_LOAD_NO_HINTING ::
+   *     Disable hinting.  This generally generates `blurrier' bitmap glyphs
+   *     when the glyph are rendered in any of the anti-aliased modes.  See
+   *     also the note below.
+   *
+   *     This flag is implied by @FT_LOAD_NO_SCALE.
+   *
+   *   FT_LOAD_RENDER ::
+   *     Call @FT_Render_Glyph after the glyph is loaded.  By default, the
+   *     glyph is rendered in @FT_RENDER_MODE_NORMAL mode.  This can be
+   *     overridden by @FT_LOAD_TARGET_XXX or @FT_LOAD_MONOCHROME.
+   *
+   *     This flag is unset by @FT_LOAD_NO_SCALE.
+   *
+   *   FT_LOAD_NO_BITMAP ::
+   *     Ignore bitmap strikes when loading.  Bitmap-only fonts ignore this
+   *     flag.
+   *
+   *     @FT_LOAD_NO_SCALE always sets this flag.
+   *
+   *   FT_LOAD_VERTICAL_LAYOUT ::
+   *     Load the glyph for vertical text layout.  In particular, the
+   *     `advance' value in the @FT_GlyphSlotRec structure is set to the
+   *     `vertAdvance' value of the `metrics' field.
+   *
+   *     In case @FT_HAS_VERTICAL doesn't return true, you shouldn't use
+   *     this flag currently.  Reason is that in this case vertical metrics
+   *     get synthesized, and those values are not always consistent across
+   *     various font formats.
+   *
+   *   FT_LOAD_FORCE_AUTOHINT ::
+   *     Prefer the auto-hinter over the font's native hinter.  See also
+   *     the note below.
+   *
+   *   FT_LOAD_PEDANTIC ::
+   *     Make the font driver perform pedantic verifications during glyph
+   *     loading.  This is mostly used to detect broken glyphs in fonts.
+   *     By default, FreeType tries to handle broken fonts also.
+   *
+   *     In particular, errors from the TrueType bytecode engine are not
+   *     passed to the application if this flag is not set; this might
+   *     result in partially hinted or distorted glyphs in case a glyph's
+   *     bytecode is buggy.
+   *
+   *   FT_LOAD_NO_RECURSE ::
+   *     Don't load composite glyphs recursively.  Instead, the font
+   *     driver should set the `num_subglyph' and `subglyphs' values of
+   *     the glyph slot accordingly, and set `glyph->format' to
+   *     @FT_GLYPH_FORMAT_COMPOSITE.  The description of subglyphs can
+   *     then be accessed with @FT_Get_SubGlyph_Info.
+   *
+   *     This flag implies @FT_LOAD_NO_SCALE and @FT_LOAD_IGNORE_TRANSFORM.
+   *
+   *   FT_LOAD_IGNORE_TRANSFORM ::
+   *     Ignore the transform matrix set by @FT_Set_Transform.
+   *
+   *   FT_LOAD_MONOCHROME ::
+   *     This flag is used with @FT_LOAD_RENDER to indicate that you want to
+   *     render an outline glyph to a 1-bit monochrome bitmap glyph, with
+   *     8~pixels packed into each byte of the bitmap data.
+   *
+   *     Note that this has no effect on the hinting algorithm used.  You
+   *     should rather use @FT_LOAD_TARGET_MONO so that the
+   *     monochrome-optimized hinting algorithm is used.
+   *
+   *   FT_LOAD_LINEAR_DESIGN ::
+   *     Keep  `linearHoriAdvance' and `linearVertAdvance' fields of
+   *     @FT_GlyphSlotRec in font units.  See @FT_GlyphSlotRec for
+   *     details.
+   *
+   *   FT_LOAD_NO_AUTOHINT ::
+   *     Disable the auto-hinter.  See also the note below.
+   *
+   *   FT_LOAD_COLOR ::
+   *     [Since 2.5] Load embedded color bitmap images.  The resulting color
+   *     bitmaps, if available, will have the @FT_PIXEL_MODE_BGRA format.
+   *     If the flag is not set and color bitmaps are found, they are
+   *     converted to 256-level gray bitmaps transparently, using the
+   *     @FT_PIXEL_MODE_GRAY format.
+   *
+   *   FT_LOAD_COMPUTE_METRICS ::
+   *     [Since 2.6.1] Compute glyph metrics from the glyph data, without
+   *     the use of bundled metrics tables (for example, the `hdmx' table in
+   *     TrueType fonts).  This flag is mainly used by font validating or
+   *     font editing applications, which need to ignore, verify, or edit
+   *     those tables.
+   *
+   *     Currently, this flag is only implemented for TrueType fonts.
+   *
+   *   FT_LOAD_BITMAP_METRICS_ONLY ::
+   *     [Since 2.7.1] Request loading of the metrics and bitmap image
+   *     information of a (possibly embedded) bitmap glyph without
+   *     allocating or copying the bitmap image data itself.  No effect if
+   *     the target glyph is not a bitmap image.
+   *
+   *     This flag unsets @FT_LOAD_RENDER.
+   *
+   *   FT_LOAD_CROP_BITMAP ::
+   *     Ignored.  Deprecated.
+   *
+   *   FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH ::
+   *     Ignored.  Deprecated.
+   *
+   * @note:
+   *   By default, hinting is enabled and the font's native hinter (see
+   *   @FT_FACE_FLAG_HINTER) is preferred over the auto-hinter.  You can
+   *   disable hinting by setting @FT_LOAD_NO_HINTING or change the
+   *   precedence by setting @FT_LOAD_FORCE_AUTOHINT.  You can also set
+   *   @FT_LOAD_NO_AUTOHINT in case you don't want the auto-hinter to be
+   *   used at all.
+   *
+   *   See the description of @FT_FACE_FLAG_TRICKY for a special exception
+   *   (affecting only a handful of Asian fonts).
+   *
+   *   Besides deciding which hinter to use, you can also decide which
+   *   hinting algorithm to use.  See @FT_LOAD_TARGET_XXX for details.
+   *
+   *   Note that the auto-hinter needs a valid Unicode cmap (either a native
+   *   one or synthesized by FreeType) for producing correct results.  If a
+   *   font provides an incorrect mapping (for example, assigning the
+   *   character code U+005A, LATIN CAPITAL LETTER Z, to a glyph depicting a
+   *   mathematical integral sign), the auto-hinter might produce useless
+   *   results.

+   *
+   * @enum:
+   *   FT_LOAD_TARGET_XXX
+   *
+   * @description:
+   *   A list of values to select a specific hinting algorithm for the
+   *   hinter.  You should OR one of these values to your `load_flags'
+   *   when calling @FT_Load_Glyph.
+   *
+   *   Note that a font's native hinters may ignore the hinting algorithm
+   *   you have specified (e.g., the TrueType bytecode interpreter).  You
+   *   can set @FT_LOAD_FORCE_AUTOHINT to ensure that the auto-hinter is
+   *   used.
+   *
+   * @values:
+   *   FT_LOAD_TARGET_NORMAL ::
+   *     The default hinting algorithm, optimized for standard gray-level
+   *     rendering.  For monochrome output, use @FT_LOAD_TARGET_MONO
+   *     instead.
+   *
+   *   FT_LOAD_TARGET_LIGHT ::
+   *     A lighter hinting algorithm for gray-level modes.  Many generated
+   *     glyphs are fuzzier but better resemble their original shape.  This
+   *     is achieved by snapping glyphs to the pixel grid only vertically
+   *     (Y-axis), as is done by FreeType's new CFF engine or Microsoft's
+   *     ClearType font renderer.  This preserves inter-glyph spacing in
+   *     horizontal text.  The snapping is done either by the native font
+   *     driver, if the driver itself and the font support it, or by the
+   *     auto-hinter.
+   *
+   *     Advance widths are rounded to integer values; however, using the
+   *     `lsb_delta' and `rsb_delta' fields of @FT_GlyphSlotRec, it is
+   *     possible to get fractional advance widths for subpixel positioning
+   *     (which is recommended to use).
+   *
+   *     If configuration option AF_CONFIG_OPTION_TT_SIZE_METRICS is active,
+   *     TrueType-like metrics are used to make this mode behave similarly
+   *     as in unpatched FreeType versions between 2.4.6 and 2.7.1
+   *     (inclusive).
+   *
+   *   FT_LOAD_TARGET_MONO ::
+   *     Strong hinting algorithm that should only be used for monochrome
+   *     output.  The result is probably unpleasant if the glyph is rendered
+   *     in non-monochrome modes.
+   *
+   *   FT_LOAD_TARGET_LCD ::
+   *     A variant of @FT_LOAD_TARGET_LIGHT optimized for horizontally
+   *     decimated LCD displays.
+   *
+   *   FT_LOAD_TARGET_LCD_V ::
+   *     A variant of @FT_LOAD_TARGET_NORMAL optimized for vertically
+   *     decimated LCD displays.
+   *
+   * @note:
+   *   You should use only _one_ of the FT_LOAD_TARGET_XXX values in your
+   *   `load_flags'.  They can't be ORed.
+   *
+   *   If @FT_LOAD_RENDER is also set, the glyph is rendered in the
+   *   corresponding mode (i.e., the mode that matches the used algorithm
+   *   best).  An exception is FT_LOAD_TARGET_MONO since it implies
+   *   @FT_LOAD_MONOCHROME.
+   *
+   *   You can use a hinting algorithm that doesn't correspond to the same
+   *   rendering mode.  As an example, it is possible to use the `light'
+   *   hinting algorithm and have the results rendered in horizontal LCD
+   *   pixel mode, with code like
+   *
+   *     {
+   *       FT_Load_Glyph( face, glyph_index,
+   *                      load_flags | FT_LOAD_TARGET_LIGHT );
+   *
+   *       FT_Render_Glyph( face->glyph, FT_RENDER_MODE_LCD );
+   *     }
+   *
+   *   In general, you should stick with one rendering mode.  For example,
+   *   switching between @FT_LOAD_TARGET_NORMAL and @FT_LOAD_TARGET_MONO
+   *   enforces a lot of recomputation for TrueType fonts, which is slow.
+   *   Another reason is caching: Selecting a different mode usually causes
+   *   changes in both the outlines and the rasterized bitmaps; it is thus
+   *   necessary to empty the cache after a mode switch to avoid false hits.

+   * <Abstract>
+   *    How to cache face, size, and glyph data with FreeType~2.
+   *
+   * <Description>
+   *   This section describes the FreeType~2 cache sub-system, which is used
+   *   to limit the number of concurrently opened @FT_Face and @FT_Size
+   *   objects, as well as caching information like character maps and glyph
+   *   images while limiting their maximum memory usage.
+   *
+   *   Note that all types and functions begin with the `FTC_' prefix.
+   *
+   *   The cache is highly portable and thus doesn't know anything about the
+   *   fonts installed on your system, or how to access them.  This implies
+   *   the following scheme:
+   *
+   *   First, available or installed font faces are uniquely identified by
+   *   @FTC_FaceID values, provided to the cache by the client.  Note that
+   *   the cache only stores and compares these values, and doesn't try to
+   *   interpret them in any way.
+   *
+   *   Second, the cache calls, only when needed, a client-provided function
+   *   to convert an @FTC_FaceID into a new @FT_Face object.  The latter is
+   *   then completely managed by the cache, including its termination
+   *   through @FT_Done_Face.  To monitor termination of face objects, the
+   *   finalizer callback in the `generic' field of the @FT_Face object can
+   *   be used, which might also be used to store the @FTC_FaceID of the
+   *   face.
+   *
+   *   Clients are free to map face IDs to anything else.  The most simple
+   *   usage is to associate them to a (pathname,face_index) pair that is
+   *   used to call @FT_New_Face.  However, more complex schemes are also
+   *   possible.
+   *
+   *   Note that for the cache to work correctly, the face ID values must be
+   *   *persistent*, which means that the contents they point to should not
+   *   change at runtime, or that their value should not become invalid.
+   *
+   *   If this is unavoidable (e.g., when a font is uninstalled at runtime),
+   *   you should call @FTC_Manager_RemoveFaceID as soon as possible, to let
+   *   the cache get rid of any references to the old @FTC_FaceID it may
+   *   keep internally.  Failure to do so will lead to incorrect behaviour
+   *   or even crashes.
+   *
+   *   To use the cache, start with calling @FTC_Manager_New to create a new
+   *   @FTC_Manager object, which models a single cache instance.  You can
+   *   then look up @FT_Face and @FT_Size objects with
+   *   @FTC_Manager_LookupFace and @FTC_Manager_LookupSize, respectively.
+   *
+   *   If you want to use the charmap caching, call @FTC_CMapCache_New, then
+   *   later use @FTC_CMapCache_Lookup to perform the equivalent of
+   *   @FT_Get_Char_Index, only much faster.
+   *
+   *   If you want to use the @FT_Glyph caching, call @FTC_ImageCache, then
+   *   later use @FTC_ImageCache_Lookup to retrieve the corresponding
+   *   @FT_Glyph objects from the cache.
+   *
+   *   If you need lots of small bitmaps, it is much more memory efficient
+   *   to call @FTC_SBitCache_New followed by @FTC_SBitCache_Lookup.  This
+   *   returns @FTC_SBitRec structures, which are used to store small
+   *   bitmaps directly.  (A small bitmap is one whose metrics and
+   *   dimensions all fit into 8-bit integers).
+   *
+   *   We hope to also provide a kerning cache in the near future.

+   *
+   *
+   *   *Hinting* *and* *antialiasing* *principles* *of* *the* *new* *engine*
+   *
+   *   The rasterizer is positioning horizontal features (e.g., ascender
+   *   height & x-height, or crossbars) on the pixel grid and minimizing the
+   *   amount of antialiasing applied to them, while placing vertical
+   *   features (vertical stems) on the pixel grid without hinting, thus
+   *   representing the stem position and weight accurately.  Sometimes the
+   *   vertical stems may be only partially black.  In this context,
+   *   `antialiasing' means that stems are not positioned exactly on pixel
+   *   borders, causing a fuzzy appearance.
+   *
+   *   There are two principles behind this approach.
+   *
+   *   1) No hinting in the horizontal direction: Unlike `superhinted'
+   *   TrueType, which changes glyph widths to accommodate regular
+   *   inter-glyph spacing, Adobe's approach is `faithful to the design' in
+   *   representing both the glyph width and the inter-glyph spacing
+   *   designed for the font.  This makes the screen display as close as it
+   *   can be to the result one would get with infinite resolution, while
+   *   preserving what is considered the key characteristics of each glyph.
+   *   Note that the distances between unhinted and grid-fitted positions at
+   *   small sizes are comparable to kerning values and thus would be
+   *   noticeable (and distracting) while reading if hinting were applied.
+   *
+   *   One of the reasons to not hint horizontally is antialiasing for LCD
+   *   screens: The pixel geometry of modern displays supplies three
+   *   vertical subpixels as the eye moves horizontally across each visible
+   *   pixel.  On devices where we can be certain this characteristic is
+   *   present a rasterizer can take advantage of the subpixels to add
+   *   increments of weight.  In Western writing systems this turns out to
+   *   be the more critical direction anyway; the weights and spacing of
+   *   vertical stems (see above) are central to Armenian, Cyrillic, Greek,
+   *   and Latin type designs.  Even when the rasterizer uses greyscale
+   *   antialiasing instead of color (a necessary compromise when one
+   *   doesn't know the screen characteristics), the unhinted vertical
+   *   features preserve the design's weight and spacing much better than
+   *   aliased type would.
+   *
+   *   2) Alignment in the vertical direction: Weights and spacing along the
+   *   y~axis are less critical; what is much more important is the visual
+   *   alignment of related features (like cap-height and x-height).  The
+   *   sense of alignment for these is enhanced by the sharpness of grid-fit
+   *   edges, while the cruder vertical resolution (full pixels instead of
+   *   1/3 pixels) is less of a problem.
+   *
+   *   On the technical side, horizontal alignment zones for ascender,
+   *   x-height, and other important height values (traditionally called
+   *   `blue zones') as defined in the font are positioned independently,
+   *   each being rounded to the nearest pixel edge, taking care of
+   *   overshoot suppression at small sizes, stem darkening, and scaling.
+   *
+   *   Hstems (this is, hint values defined in the font to help align
+   *   horizontal features) that fall within a blue zone are said to be
+   *   `captured' and are aligned to that zone.  Uncaptured stems are moved
+   *   in one of four ways, top edge up or down, bottom edge up or down.
+   *   Unless there are conflicting hstems, the smallest movement is taken
+   *   to minimize distortion.

+   *   Controlling the TrueType driver module.
+   *
+   * @description:
+   *   While FreeType's TrueType driver doesn't expose API functions by
+   *   itself, it is possible to control its behaviour with @FT_Property_Set
+   *   and @FT_Property_Get.  The following lists the available properties
+   *   together with the necessary macros and structures.
+   *
+   *   The TrueType driver's module name is `truetype'.
+   *
+   *   A single property @interpreter-version is available, as documented in
+   *   the @properties section.
+   *
+   *   We start with a list of definitions, kindly provided by Greg
+   *   Hitchcock.
+   *
+   *   _Bi-Level_ _Rendering_
+   *
+   *   Monochromatic rendering, exclusively used in the early days of
+   *   TrueType by both Apple and Microsoft.  Microsoft's GDI interface
+   *   supported hinting of the right-side bearing point, such that the
+   *   advance width could be non-linear.  Most often this was done to
+   *   achieve some level of glyph symmetry.  To enable reasonable
+   *   performance (e.g., not having to run hinting on all glyphs just to
+   *   get the widths) there was a bit in the head table indicating if the
+   *   side bearing was hinted, and additional tables, `hdmx' and `LTSH', to
+   *   cache hinting widths across multiple sizes and device aspect ratios.
+   *
+   *   _Font_ _Smoothing_
+   *
+   *   Microsoft's GDI implementation of anti-aliasing.  Not traditional
+   *   anti-aliasing as the outlines were hinted before the sampling.  The
+   *   widths matched the bi-level rendering.
+   *
+   *   _ClearType_ _Rendering_
+   *
+   *   Technique that uses physical subpixels to improve rendering on LCD
+   *   (and other) displays.  Because of the higher resolution, many methods
+   *   of improving symmetry in glyphs through hinting the right-side
+   *   bearing were no longer necessary.  This lead to what GDI calls
+   *   `natural widths' ClearType, see
+   *   http://www.beatstamm.com/typography/RTRCh4.htm#Sec21.  Since hinting
+   *   has extra resolution, most non-linearity went away, but it is still
+   *   possible for hints to change the advance widths in this mode.
+   *
+   *   _ClearType_ _Compatible_ _Widths_
+   *
+   *   One of the earliest challenges with ClearType was allowing the
+   *   implementation in GDI to be selected without requiring all UI and
+   *   documents to reflow.  To address this, a compatible method of
+   *   rendering ClearType was added where the font hints are executed once
+   *   to determine the width in bi-level rendering, and then re-run in
+   *   ClearType, with the difference in widths being absorbed in the font
+   *   hints for ClearType (mostly in the white space of hints); see
+   *   http://www.beatstamm.com/typography/RTRCh4.htm#Sec20.  Somewhat by
+   *   definition, compatible width ClearType allows for non-linear widths,
+   *   but only when the bi-level version has non-linear widths.
+   *
+   *   _ClearType_ _Subpixel_ _Positioning_
+   *
+   *   One of the nice benefits of ClearType is the ability to more crisply
+   *   display fractional widths; unfortunately, the GDI model of integer
+   *   bitmaps did not support this.  However, the WPF and Direct Write
+   *   frameworks do support fractional widths.  DWrite calls this `natural
+   *   mode', not to be confused with GDI's `natural widths'.  Subpixel
+   *   positioning, in the current implementation of Direct Write,
+   *   unfortunately does not support hinted advance widths, see
+   *   http://www.beatstamm.com/typography/RTRCh4.htm#Sec22.  Note that the
+   *   TrueType interpreter fully allows the advance width to be adjusted in
+   *   this mode, just the DWrite client will ignore those changes.
+   *
+   *   _ClearType_ _Backward_ _Compatibility_
+   *
+   *   This is a set of exceptions made in the TrueType interpreter to
+   *   minimize hinting techniques that were problematic with the extra
+   *   resolution of ClearType; see
+   *   http://www.beatstamm.com/typography/RTRCh4.htm#Sec1 and
+   *   https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx.
+   *   This technique is not to be confused with ClearType compatible
+   *   widths.  ClearType backward compatibility has no direct impact on
+   *   changing advance widths, but there might be an indirect impact on
+   *   disabling some deltas.  This could be worked around in backward
+   *   compatibility mode.
+   *
+   *   _Native_ _ClearType_ _Mode_
+   *
+   *   (Not to be confused with `natural widths'.)  This mode removes all
+   *   the exceptions in the TrueType interpreter when running with
+   *   ClearType.  Any issues on widths would still apply, though.

+   *   All glyphs that pass through the auto-hinter will be emboldened
+   *   unless this property is set to TRUE.  The same is true for the CFF,
+   *   Type~1, and CID font modules if the `Adobe' engine is selected (which
+   *   is the default).
+   *
+   *   Stem darkening emboldens glyphs at smaller sizes to make them more
+   *   readable on common low-DPI screens when using linear alpha blending
+   *   and gamma correction, see @FT_Render_Glyph.  When not using linear
+   *   alpha blending and gamma correction, glyphs will appear heavy and
+   *   fuzzy!
+   *
+   *   Gamma correction essentially lightens fonts since shades of grey are
+   *   shifted to higher pixel values (=~higher brightness) to match the
+   *   original intention to the reality of our screens.  The side-effect is
+   *   that glyphs `thin out'.  Mac OS~X and Adobe's proprietary font
+   *   rendering library implement a counter-measure: stem darkening at
+   *   smaller sizes where shades of gray dominate.  By emboldening a glyph
+   *   slightly in relation to its pixel size, individual pixels get higher
+   *   coverage of filled-in outlines and are therefore `blacker'.  This
+   *   counteracts the `thinning out' of glyphs, making text remain readable
+   *   at smaller sizes.
+   *
+   *   By default, the Adobe engines for CFF, Type~1, and CID fonts darken
+   *   stems at smaller sizes, regardless of hinting, to enhance contrast. 
+   *   Setting this property, stem darkening gets switched off.
+   *
+   *   For the auto-hinter, stem-darkening is experimental currently and

+   * @description:
+   *   A list of constants used for the @interpreter-version property to
+   *   select the hinting engine for Truetype fonts.
+   *
+   *   The numeric value in the constant names represents the version
+   *   number as returned by the `GETINFO' bytecode instruction.
+   *
+   * @values:
+   *   TT_INTERPRETER_VERSION_35 ::
+   *     Version~35 corresponds to MS rasterizer v.1.7 as used e.g. in
+   *     Windows~98; only grayscale and B/W rasterizing is supported.
+   *
+   *   TT_INTERPRETER_VERSION_38 ::
+   *     Version~38 corresponds to MS rasterizer v.1.9; it is roughly
+   *     equivalent to the hinting provided by DirectWrite ClearType (as can
+   *     be found, for example, in the Internet Explorer~9 running on
+   *     Windows~7).  It is used in FreeType to select the `Infinality'
+   *     subpixel hinting code.  The code may be removed in a future
+   *     version.
+   *
+   *   TT_INTERPRETER_VERSION_40 ::
+   *     Version~40 corresponds to MS rasterizer v.2.1; it is roughly
+   *     equivalent to the hinting provided by DirectWrite ClearType (as can
+   *     be found, for example, in Microsoft's Edge Browser on Windows~10).
+   *     It is used in FreeType to select the `minimal' subpixel hinting
+   *     code, a stripped-down and higher performance version of the
+   *     `Infinality' code.
+   *
+   * @note:
+   *   This property controls the behaviour of the bytecode interpreter
+   *   and thus how outlines get hinted.  It does *not* control how glyph
+   *   get rasterized!  In particular, it does not control subpixel color
+   *   filtering.
+   *
+   *   If FreeType has not been compiled with the configuration option
+   *   TT_CONFIG_OPTION_SUBPIXEL_HINTING, selecting version~38 or~40 causes
+   *   an `FT_Err_Unimplemented_Feature' error.
+   *
+   *   Depending on the graphics framework, Microsoft uses different
+   *   bytecode and rendering engines.  As a consequence, the version
+   *   numbers returned by a call to the `GETINFO' bytecode instruction are
+   *   more convoluted than desired.
+   *
+   *   Here are two tables that try to shed some light on the possible
+   *   values for the MS rasterizer engine, together with the additional

+   *   The `version' field gives a rough orientation only, since some

+   *   Color and Gray ClearType are the two available variants of
+   *   `Y-direction ClearType', meaning grayscale rasterization along the
+   *   Y-direction; the name used in the TrueType specification for this
+   *   feature is `symmetric smoothing'.  `Classic ClearType' is the
+   *   original algorithm used before introducing a modified version in
+   *   Win~XP.  Another name for v1.6's grayscale rendering is `font
+   *   smoothing', and `Color ClearType' is sometimes also called `DWrite
+   *   ClearType'.  To differentiate between today's Color ClearType and the
+   *   earlier ClearType variant with B/W rendering along the vertical axis,
+   *   the latter is sometimes called `GDI ClearType'.
+   *
+   *   `Normal' and `high' sampling describe the (virtual) resolution to
+   *   access the rasterized outline after the hinting process.  `Normal'
+   *   means 1 sample per grid line (i.e., B/W).  In the current Microsoft
+   *   implementation, `high' means an extra virtual resolution of 16x16 (or
+   *   16x1) grid lines per pixel for bytecode instructions like `MIRP'.
+   *   After hinting, these 16 grid lines are mapped to 6x5 (or 6x1) grid
+   *   lines for color filtering if Color ClearType is activated.
+   *
+   *   Note that `Gray ClearType' is essentially the same as v1.6's
+   *   grayscale rendering.  However, the GETINFO instruction handles it
+   *   differently: v1.6 returns bit~12 (hinting for grayscale), while v2.1
+   *   returns bits~13 (hinting for ClearType), 18 (symmetrical smoothing),
+   *   and~19 (Gray ClearType).  Also, this mode respects bits 2 and~3 for
+   *   the version~1 gasp table exclusively (like Color ClearType), while
+   *   v1.6 only respects the values of version~0 (bits 0 and~1).
+   *
+   *   Keep in mind that the features of the above interpreter versions
+   *   might not map exactly to FreeType features or behavior because it is
+   *   a fundamentally different library with different internals.

+   * @description:
+   *   Currently, three versions are available, two representing the
+   *   bytecode interpreter with subpixel hinting support (old `Infinality'
+   *   code and new stripped-down and higher performance `minimal' code) and
+   *   one without, respectively.  The default is subpixel support if
+   *   TT_CONFIG_OPTION_SUBPIXEL_HINTING is defined, and no subpixel support
+   *   otherwise (since it isn't available then).
+   *
+   *   If subpixel hinting is on, many TrueType bytecode instructions behave
+   *   differently compared to B/W or grayscale rendering (except if `native
+   *   ClearType' is selected by the font).  Microsoft's main idea is to
+   *   render at a much increased horizontal resolution, then sampling down
+   *   the created output to subpixel precision.  However, many older fonts
+   *   are not suited to this and must be specially taken care of by
+   *   applying (hardcoded) tweaks in Microsoft's interpreter.
+   *
+   *   Details on subpixel hinting and some of the necessary tweaks can be
+   *   found in Greg Hitchcock's whitepaper at
+   *   `https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx'.
+   *   Note that FreeType currently doesn't really `subpixel hint' (6x1, 6x2,
+   *   or 6x5 supersampling) like discussed in the paper.  Depending on the
+   *   chosen interpreter, it simply ignores instructions on vertical stems
+   *   to arrive at very similar results.

+   *
+   *   The auto-hinter provides various script modules to hint glyphs.
+   *   Examples of supported scripts are Latin or CJK.  Before a glyph is
+   *   auto-hinted, the Unicode character map of the font gets examined, and
+   *   the script is then determined based on Unicode character ranges, see
+   *   below.
+   *
+   *   OpenType fonts, however, often provide much more glyphs than
+   *   character codes (small caps, superscripts, ligatures, swashes, etc.),
+   *   to be controlled by so-called `features'.  Handling OpenType features
+   *   can be quite complicated and thus needs a separate library on top of
+   *   FreeType.
+   *
+   *   The mapping between glyph indices and scripts (in the auto-hinter
+   *   sense, see the @FT_AUTOHINTER_SCRIPT_XXX values) is stored as an
+   *   array with `num_glyphs' elements, as found in the font's @FT_Face
+   *   structure.  The `glyph-to-script-map' property returns a pointer to
+   *   this array, which can be modified as needed.  Note that the
+   *   modification should happen before the first glyph gets processed by
+   *   the auto-hinter so that the global analysis of the font shapes
+   *   actually uses the modified mapping.
+   *
+   *   The following example code demonstrates how to access it (omitting
+   *   the error handling).

+   *
+   * @description:

+   *
+   *   If FreeType gets compiled with option AF_CONFIG_OPTION_USE_WARPER to
+   *   activate the warp hinting code in the auto-hinter, this property
+   *   switches warping on and off.
+   *
+   *   Warping only works in `normal' auto-hinting mode replacing it.
+   *   The idea of the code is to slightly scale and shift a glyph along
+   *   the non-hinted dimension (which is usually the horizontal axis) so
+   *   that as much of its segments are aligned (more or less) to the grid.
+   *   To find out a glyph's optimal scaling and shifting value, various
+   *   parameter combinations are tried and scored.
+   *
+   *   By default, warping is off.  The example below shows how to switch on
+   *   warping (omitting the error handling).
+   *
+   *   {
+   *     FT_Library  library;
+   *     FT_Bool     warping = 1;
+   *
+   *

+   *                               "warping", &warping );
+   *   }
+   *
+   * @note:
+   *   This property can be used with @FT_Property_Get also.
+   *
+   *   This property can be set via the `FREETYPE_PROPERTIES' environment
+   *   variable (using values 1 and 0 for `on' and `off', respectively).
+   *
+   *   The warping code can also change advance widths.  Have a look at the
+   *   `lsb_delta' and `rsb_delta' fields in the @FT_GlyphSlotRec structure
+   *   for details on improving inter-glyph distances while rendering.
+   *
+   *   Since warping is a global property of the auto-hinter it is best to
+   *   change its value before rendering any face.  Otherwise, you should
+   *   reload all faces that get auto-hinted in `normal' hinting mode.

+   *   FT_GASP_DO_GRIDFIT ::

+   *   Apart from that, all other tables are loaded normally from the font
+   *   file.  This mode is useful when FreeType is used within another
+   *   engine, e.g., a PostScript Imaging Processor.
+   *
+   *   To enable this mode, you must use @FT_Open_Face, passing an
+   *   @FT_Parameter with the @FT_PARAM_TAG_INCREMENTAL tag and an
+   *   @FT_Incremental_Interface value.  See the comments for
+   *   @FT_Incremental_InterfaceRec for an example.

+   * @title:
+   *   LCD Filtering
+   *
+   * @abstract:
+   *   Reduce color fringes of subpixel-rendered bitmaps.
+   *
+   * @description:
+   *   Should you #define FT_CONFIG_OPTION_SUBPIXEL_RENDERING in your
+   *   `ftoption.h', which enables patented ClearType-style rendering,
+   *   the LCD-optimized glyph bitmaps should be filtered to reduce color
+   *   fringes inherent to this technology.  The default FreeType LCD
+   *   rendering uses different technology, and API described below,
+   *   although available, does nothing.
+   *
+   *   ClearType-style LCD rendering exploits the color-striped structure of
+   *   LCD pixels, increasing the available resolution in the direction of
+   *   the stripe (usually horizontal RGB) by a factor of~3.  Since these
+   *   subpixels are color pixels, using them unfiltered creates severe
+   *   color fringes.  Use the @FT_Library_SetLcdFilter API to specify a
+   *   low-pass filter, which is then applied to subpixel-rendered bitmaps
+   *   generated through @FT_Render_Glyph.  The filter sacrifices some of
+   *   the higher resolution to reduce color fringes, making the glyph image
+   *   slightly blurrier.  Positional improvements will remain.
+   *
+   *   A filter should have two properties:
+   *
+   *   1) It should be normalized, meaning the sum of the 5~components
+   *      should be 256 (0x100).  It is possible to go above or under this
+   *      target sum, however: going under means tossing out contrast, going
+   *      over means invoking clamping and thereby non-linearities that
+   *      increase contrast somewhat at the expense of greater distortion
+   *      and color-fringing.  Contrast is better enhanced through stem
+   *      darkening.
+   *
+   *   2) It should be color-balanced, meaning a filter `{~a, b, c, b, a~}'
+   *      where a~+ b~=~c.  It distributes the computed coverage for one
+   *      subpixel to all subpixels equally, sacrificing some won resolution
+   *      but drastically reducing color-fringing.  Positioning improvements
+   *      remain!  Note that color-fringing can only really be minimized
+   *      when using a color-balanced filter and alpha-blending the glyph
+   *      onto a surface in linear space; see @FT_Render_Glyph.
+   *
+   *   Regarding the form, a filter can be a `boxy' filter or a `beveled'
+   *   filter.  Boxy filters are sharper but are less forgiving of non-ideal
+   *   gamma curves of a screen (viewing angles!), beveled filters are
+   *   fuzzier but more tolerant.
+   *
+   *   Examples:
+   *
+   *   - [0x10 0x40 0x70 0x40 0x10] is beveled and neither balanced nor
+   *     normalized.
+   *
+   *   - [0x1A 0x33 0x4D 0x33 0x1A] is beveled and balanced but not
+   *     normalized.
+   *
+   *   - [0x19 0x33 0x66 0x4c 0x19] is beveled and normalized but not
+   *     balanced.
+   *
+   *   - [0x00 0x4c 0x66 0x4c 0x00] is boxily beveled and normalized but not
+   *     balanced.
+   *
+   *   - [0x00 0x55 0x56 0x55 0x00] is boxy, normalized, and almost
+   *     balanced.
+   *
+   *   - [0x08 0x4D 0x56 0x4D 0x08] is beveled, normalized and, almost
+   *     balanced.
+   *
+   *   The filter affects glyph bitmaps rendered through @FT_Render_Glyph,
+   *   @FT_Load_Glyph, and @FT_Load_Char.  It does _not_ affect the output
+   *   of @FT_Outline_Render and @FT_Outline_Get_Bitmap.
+   *
+   *   If this feature is activated, the dimensions of LCD glyph bitmaps are
+   *   either wider or taller than the dimensions of the corresponding
+   *   outline with regard to the pixel grid.  For example, for
+   *   @FT_RENDER_MODE_LCD, the filter adds 3~subpixels to the left, and
+   *   3~subpixels to the right.  The bitmap offset values are adjusted
+   *   accordingly, so clients shouldn't need to modify their layout and
+   *   glyph positioning code when enabling the filter.
+   *
+   *   It is important to understand that linear alpha blending and gamma
+   *   correction is critical for correctly rendering glyphs onto surfaces
+   *   without artifacts and even more critical when subpixel rendering is
+   *   involved.
+   *
+   *   Each of the 3~alpha values (subpixels) is independently used to blend
+   *   one color channel.  That is, red alpha blends the red channel of the
+   *   text color with the red channel of the background pixel.  The
+   *   distribution of density values by the color-balanced filter assumes
+   *   alpha blending is done in linear space; only then color artifacts
+   *   cancel out.

+   * @enum:
+   *   FT_LcdFilter
+   *
+   * @description:
+   *   A list of values to identify various types of LCD filters.
+   *
+   * @values:
+   *   FT_LCD_FILTER_NONE ::
+   *     Do not perform filtering.  When used with subpixel rendering, this
+   *     results in sometimes severe color fringes.
+   *
+   *   FT_LCD_FILTER_DEFAULT ::
+   *     The default filter reduces color fringes considerably, at the cost
+   *     of a slight blurriness in the output.
+   *
+   *     It is a beveled, normalized, and color-balanced five-tap filter
+   *     that is more forgiving to screens with non-ideal gamma curves and
+   *     viewing angles.  Note that while color-fringing is reduced, it can
+   *     only be minimized by using linear alpha blending and gamma
+   *     correction to render glyphs onto surfaces.  The default filter
+   *     weights are [0x08 0x4D 0x56 0x4D 0x08].
+   *
+   *   FT_LCD_FILTER_LIGHT ::
+   *     The light filter is a variant that is sharper at the cost of
+   *     slightly more color fringes than the default one.
+   *
+   *     It is a boxy, normalized, and color-balanced three-tap filter that
+   *     is less forgiving to screens with non-ideal gamma curves and
+   *     viewing angles.  This filter works best when the rendering system
+   *     uses linear alpha blending and gamma correction to render glyphs
+   *     onto surfaces.  The light filter weights are
+   *     [0x00 0x55 0x56 0x55 0x00].
+   *
+   *   FT_LCD_FILTER_LEGACY ::
+   *     This filter corresponds to the original libXft color filter.  It
+   *     provides high contrast output but can exhibit really bad color
+   *     fringes if glyphs are not extremely well hinted to the pixel grid.
+   *     In other words, it only works well if the TrueType bytecode
+   *     interpreter is enabled *and* high-quality hinted fonts are used.
+   *
+   *     This filter is only provided for comparison purposes, and might be
+   *     disabled or stay unsupported in the future.
+   *
+   *   FT_LCD_FILTER_LEGACY1 ::
+   *     For historical reasons, the FontConfig library returns a different
+   *     enumeration value for legacy LCD filtering.  To make code work that
+   *     (incorrectly) forwards FontConfig's enumeration value to
+   *     @FT_Library_SetLcdFilter without proper mapping, it is thus easiest
+   *     to have another enumeration value, which is completely equal to
+   *     `FT_LCD_FILTER_LEGACY'.
+   *
+   * @since:
+   *   2.3.0 (`FT_LCD_FILTER_LEGACY1' since 2.6.2)

+  *   source :: The source stream.
+  *
+  * @return:
+  *   FreeType error code.  0~means success.
+  *
+  * @note:
+  *   The source stream must be opened _before_ calling this function.
+  *
+  *   Calling the internal function `FT_Stream_Close' on the new stream will
+  *   *not* call `FT_Stream_Close' on the source stream.  None of the stream
+  *   objects will be released to the heap.
+  *
+  *   The stream implementation is very basic and resets the decompression
+  *   process each time seeking backwards is needed within the stream
+  *
+  *   In certain builds of the library, LZW compression recognition is
+  *   automatically handled when calling @FT_New_Face or @FT_Open_Face.
+  *   This means that if no font driver is capable of handling the raw
+  *   compressed file, the library will try to open a LZW stream from it
+  *   and re-open the face with it.
+  *
+  *   This function may return `FT_Err_Unimplemented_Feature' if your build
+  *   of FreeType was not compiled with LZW support.

+   *
+   * @description:
+   *   A list of valid values for the `charset' byte in
+   *   @FT_WinFNT_HeaderRec.  Exact mapping tables for the various cpXXXX
+   *   encodings (except for cp1361) can be found at
+   *   ftp://ftp.unicode.org/Public in the MAPPINGS/VENDORS/MICSFT/WINDOWS
+   *   subdirectory.  cp1361 is roughly a superset of
+   *   MAPPINGS/OBSOLETE/EASTASIA/KSC/JOHAB.TXT.
+   *
+   * @values:
+   *   FT_WinFNT_ID_DEFAULT ::
+   *     This is used for font enumeration and font creation as a
+   *     `don't care' value.  Valid font files don't contain this value.
+   *     When querying for information about the character set of the font
+   *     that is currently selected into a specified device context, this
+   *     return value (of the related Windows API) simply denotes failure.
+   *
+   *   FT_WinFNT_ID_SYMBOL ::
+   *     There is no known mapping table available.
+   *
+   *   FT_WinFNT_ID_MAC ::
+   *     Mac Roman encoding.
+   *
+   *   FT_WinFNT_ID_OEM ::
+   *     From Michael Poettgen <michael@poettgen.de>:
+   *
+   *       The `Windows Font Mapping' article says that FT_WinFNT_ID_OEM
+   *       is used for the charset of vector fonts, like `modern.fon',
+   *       `roman.fon', and `script.fon' on Windows.
+   *
+   *       The `CreateFont' documentation says: The FT_WinFNT_ID_OEM value
+   *       specifies a character set that is operating-system dependent.
+   *
+   *       The `IFIMETRICS' documentation from the `Windows Driver
+   *       Development Kit' says: This font supports an OEM-specific
+   *       character set.  The OEM character set is system dependent.
+   *
+   *       In general OEM, as opposed to ANSI (i.e., cp1252), denotes the
+   *       second default codepage that most international versions of
+   *       Windows have.  It is one of the OEM codepages from
+   *
+   *         https://msdn.microsoft.com/en-us/goglobal/bb964655,
+   *
+   *       and is used for the `DOS boxes', to support legacy applications.
+   *       A German Windows version for example usually uses ANSI codepage
+   *       1252 and OEM codepage 850.
+   *
+   *   FT_WinFNT_ID_CP874 ::
+   *     A superset of Thai TIS 620 and ISO 8859-11.
+   *
+   *   FT_WinFNT_ID_CP932 ::
+   *     A superset of Japanese Shift-JIS (with minor deviations).
+   *
+   *   FT_WinFNT_ID_CP936 ::
+   *     A superset of simplified Chinese GB 2312-1980 (with different
+   *     ordering and minor deviations).
+   *
+   *   FT_WinFNT_ID_CP949 ::
+   *     A superset of Korean Hangul KS~C 5601-1987 (with different
+   *     ordering and minor deviations).
+   *
+   *   FT_WinFNT_ID_CP950 ::

+   *
+   *   FT_WinFNT_ID_CP1250 ::

+   *     ordering).
+   *
+   *   FT_WinFNT_ID_CP1251 ::
+   *     A superset of Russian ISO 8859-5 (with different ordering).
+   *
+   *   FT_WinFNT_ID_CP1252 ::
+   *     ANSI encoding.  A superset of ISO 8859-1.

+   *     A superset of Greek ISO 8859-7 (with minor modifications).
+   *
+   *   FT_WinFNT_ID_CP1254 ::
+   *     A superset of Turkish ISO 8859-9.

+   *
+   *   FT_WinFNT_ID_CP1258 ::
+   *     For Vietnamese.  This encoding doesn't cover all necessary
+   *     characters.

+   *     This rewinds the recorder and prepare it for new input.
+   *
+   *   - For each hint found in the glyph charstring, call the corresponding
+   *     method (`stem', `stem3', or `reset').  Note that these functions do
+   *     not return an error code.
+   *
+   *   - Close the recording session by calling the `close' method.  It
+   *     returns an error code if the hints were invalid or something
+   *     strange happened (e.g., memory shortage).

+   *     This rewinds the recorder and prepare it for new input.
+   *
+   *   - For each hint found in the glyph charstring, call the corresponding
+   *     method (`stems', `hintmask', `counters').  Note that these
+   *     functions do not return an error code.
+   *
+   *   - Close the recording session by calling the `close' method.  It
+   *     returns an error code if the hints were invalid or something
+   *     strange happened (e.g., memory shortage).
+   *
+   *   The hints accumulated in the object can later be used by the

+   *
+   * @input:
+   *    face ::
+   *       PostScript face handle.
+   *
+   *    key ::
+   *       An enumeration value representing the dictionary key to retrieve.
+   *
+   *    idx ::
+   *       For array values, this specifies the index to be returned.
+   *
+   *    value ::
+   *       A pointer to memory into which to write the value.
+   *
+   *    valen_len ::
+   *       The size, in bytes, of the memory supplied for the value.
+   *
+   * @output:
+   *    value ::
+   *       The value matching the above key, if it exists.
+   *
+   * @return:
+   *    The amount of memory (in bytes) required to hold the requested
+   *    value (if it exists, -1 otherwise).
+   *
+   * @note:
+   *    The values returned are not pointers into the internal structures of
+   *    the face, but are `fresh' copies, so that the memory containing them
+   *    belongs to the calling application.  This also enforces the
+   *    `read-only' nature of these values, i.e., this function cannot be
+   *    used to manipulate the face.
+   *
+   *    `value' is a void pointer because the values returned can be of
+   *    various types.
+   *
+   *    If either `value' is NULL or `value_len' is too small, just the
+   *    required memory size for the requested entry is returned.
+   *
+   *    The `idx' parameter is used, not only to retrieve elements of, for
+   *    example, the FontMatrix or FontBBox, but also to retrieve name keys
+   *    from the CharStrings dictionary, and the charstrings themselves.  It
+   *    is ignored for atomic values.
+   *
+   *    PS_DICT_BLUE_SCALE returns a value that is scaled up by 1000.  To
+   *    get the value as in the font stream, you need to divide by
+   *    65536000.0 (to remove the FT_Fixed scale, and the x1000 scale).
+   *
+   *    IMPORTANT: Only key/value pairs read by the FreeType interpreter can
+   *    be retrieved.  So, for example, PostScript procedures such as NP,
+   *    ND, and RD are not available.  Arbitrary keys are, obviously, not be
+   *    available either.
+   *
+   *    If the font's format is not PostScript-based, this function returns
+   *    the `FT_Err_Invalid_Argument' error code.

+   *     definitions found in the @FT_TRUETYPE_TAGS_H file, or forge a new
+   *     one with @FT_MAKE_TAG.
+   *
+   *   offset ::

+   *
+   * @output:
+   *   buffer ::

+   * @inout:
+   *   length ::
+   *     If the `length' parameter is NULL, try to load the whole table.
+   *     Return an error code if it fails.
+   *
+   *     Else, if `*length' is~0, exit immediately while returning the

+   *     starting offset.
+   *
+   * @return:
+   *   FreeType error code.  0~means success.
+   *
+   * @note:
+   *   If you need to determine the table's length you should first call this
+   *   function with `*length' set to~0, as in the following example:
+   *
+   *     {
+   *       FT_ULong  length = 0;
+   *
+   *
+   *       error = FT_Load_Sfnt_Table( face, tag, 0, NULL, &length );
+   *       if ( error ) { ... table does not exist ... }
+   *
+   *       buffer = malloc( length );
+   *       if ( buffer == NULL ) { ... not enough memory ... }
+   *
+   *       error = FT_Load_Sfnt_Table( face, tag, 0, buffer, &length );
+   *       if ( error ) { ... could not load table ... }
+   *     }
+   *
+   *   Note that structures like @TT_Header or @TT_OS2 can't be used with
+   *   this function; they are limited to @FT_Get_Sfnt_Table.  Reason is that
+   *   those structures depend on the processor architecture, with varying
+   *   size (e.g. 32bit vs. 64bit) or order (big endian vs. little endian).

+
+
+// This file contains data specific to blue zones.  It gets processed by
+// a script to simulate `jagged arrays', with enumeration values holding
+// offsets into the arrays.
+//
+// The format of the file is rather simple:  A section starts with three
+// labels separated by whitespace and followed by a colon (everything in a
+// single line); the first label gives the name of the enumeration template,
+// the second the name of the array template, and the third the name of the
+// `maximum' template.  The script then fills the corresponding templates
+// (indicated by `@' characters around the name).
+//
+// A section contains one or more data records.  Each data record consists
+// of two or more lines.  The first line holds the enumeration name, and the
+// remaining lines the corresponding array data.
+//
+// There are two possible representations for array data.
+//
+// - A string of characters or character clusters (for example, representing
+//   Aksharas, Devanagari syllables) in UTF-8 encoding enclosed in double
+//   quotes, using C syntax, where the elements are separated by spaces.
+//   There can be only one string per line, thus the starting and ending
+//   double quote must be the first and last character in the line,
+//   respectively, ignoring whitespace before and after the string.  If
+//   there are multiple strings (in multiple lines), they are concatenated
+//   to a single string.  In the output, a string gets represented as a
+//   series of singles bytes, followed by a zero byte.  The enumeration
+//   values simply hold byte offsets to the start of the corresponding
+//   strings.
+//
+//   For strings, the `maximum' template holds the maximum number of
+//   non-space characters in all strings.
+//
+// - Data blocks enclosed in balanced braces, which get copied verbatim and
+//   which can span multiple lines.  The opening brace of a block must be
+//   the first character of a line (ignoring whitespace), and the closing
+//   brace the last (ignoring whitespace also).  The script appends a comma
+//   character after each block and counts the number of blocks to set the
+//   enumeration values.
+//
+//   For data blocks, the `maximum' template holds the maximum number of
+//   array elements.
+//
+// A section can contain either strings only or data blocks only.
+//
+// A comment line starts with `//'; it gets removed.  A preprocessor
+// directive line (using the standard syntax of `cpp') starts with `#' and
+// gets copied verbatim to both the enumeration and the array.  Whitespace
+// outside of a string is insignificant.
+//
+// Preprocessor directives are ignored while the script computes maximum
+// values; this essentially means that the maximum values can easily be too
+// large.  Given that the purpose of those values is to create local
+// fixed-size arrays at compile time for further processing of the blue zone
+// data, this isn't a problem.  Note the final zero byte of a string is not
+// counted.  Note also that the count holds the number of UTF-8 encoded
+// characters, not bytes.

+// The AF_BLUE_PROPERTY_XXX flags are defined in `afblue.h'; here some
+// explanations.
+//
+// A blue zone in general is defined by a reference and an overshoot line.
+// During the hinting process, all coordinate values between those two lines
+// are set equal to the reference value, provided that the blue zone is not
+// wider than 0.75 pixels (otherwise the blue zone gets ignored).  All
+// entries must have `AF_BLUE_STRING_MAX' as the final line.
+//
+// During the glyph analysis, edges are sorted from bottom to top, and then
+// sequentially checked, edge by edge, against the blue zones in the order
+// given below.
+//
+//
+// latin auto-hinter
+// -----------------
+//
+// Characters in a blue string are automatically classified as having a flat
+// (reference) or a round (overshoot) extremum.  The blue zone is then set
+// up by the mean values of all flat extrema and all round extrema,
+// respectively.  Only horizontal blue zones (i.e., adjusting vertical
+// coordinate values) are supported.
+//
+// Some scripts like Khmer need character composition to get all necessary
+// blue zones, since Unicode only provides an abstract data model that
+// doesn't represent all possible glyph shapes.  For such character
+// clusters, the HarfBuzz library is used to convert them into the
+// corresponding glyphs.  The largest glyph element (where `largest' can be
+// either `largest ascender' or `largest descender') then defines the
+// corresponding flat or round extremum.
+//
+// For the latin auto-hinter, the overshoot should be larger than the
+// reference for top zones, and vice versa for bottom zones.
+//
+//   LATIN_TOP
+//     Take the maximum flat and round coordinate values of the blue string
+//     characters for computing the blue zone's reference and overshoot
+//     values.
+//
+//     If not set, take the minimum values.
+//
+//     Mutually exclusive with `LATIN_SUB_TOP'.
+//
+//   LATIN_SUB_TOP
+//     For all glyphs of a character cluster, compute the maximum flat
+//     and round coordinate values of each component, then take the
+//     smallest of the maximum values.  The idea is to get the top of
+//     subscript glyphs, as used in Khmer, for example.  Note that
+//     this mechanism doesn't work for ordinary ligatures.
+//
+//     This flags indicates a secondary blue zone: It gets removed if
+//     there is a non-LATIN_SUB_TOP blue zone at the same coordinate
+//     value (after scaling).
+//
+//     Mutually exclusive with `LATIN_TOP'.
+//
+//   LATIN_NEUTRAL
+//     Ignore round extrema and define the blue zone with flat values only.
+//     Both top and bottom of contours can match.  This is useful for
+//     scripts like Devanagari where vowel signs attach to the base
+//     character and are implemented as components of composite glyphs.
+//
+//     If not set, both round and flat extrema are taken into account.
+//     Additionally, only the top or the bottom of a contour can match,
+//     depending on the LATIN_TOP flag.
+//
+//     Neutral blue zones should always follow non-neutral blue zones.
+//
+//   LATIN_X_HEIGHT
+//     Scale all glyphs vertically from the corresponding script to make the
+//     reference line of this blue zone align on the grid.  The scaling
+//     takes place before all other blue zones get aligned to the grid.
+//     Only one blue character string of a script style can have this flag.
+//
+//   LATIN_LONG
+//     Apply an additional constraint for blue zone values: Don't
+//     necessarily use the extremum as-is but a segment of the topmost (or
+//     bottommost) contour that is longer than a heuristic threshold, and
+//     which is not too far away vertically from the real extremum.  This
+//     ensures that small bumps in the outline are ignored (for example, the
+//     `vertical serifs' found in many Hebrew glyph designs).
+//
+//     The segment must be at least EM/25 font units long, and the distance
+//     to the extremum must be smaller than EM/4.
+//
+//
+// cjk auto-hinter
+// ---------------
+//
+// Characters in a blue string are *not* automatically classified.  Instead,
+// first come the characters used for the overshoot value, then the
+// character `|', then the characters used for the reference value
+// (everything separated by space characters).  The blue zone is then set up
+// by the mean values of all reference values and all overshoot values,
+// respectively.  Both horizontal and vertical blue zones (i.e., adjusting
+// vertical and horizontal coordinate values, respectively) are supported.
+//
+// For the cjk auto-hinter, the overshoot should be smaller than the
+// reference for top zones, and vice versa for bottom zones.
+//
+//   CJK_TOP
+//     Take the maximum flat and round coordinate values of the blue string
+//     characters.  If not set, take the minimum values.
+//
+//   CJK_RIGHT
+//     A synonym for CJK_TOP.  If CJK_HORIZ is set, this flag indicates the
+//     right blue zone, taking horizontal maximum values.
+//
+//   CJK_HORIZ
+//     Define a blue zone for horizontal hinting (i.e., vertical blue
+//     zones).  If not set, this is a blue zone for vertical hinting.

+   *  Segments
+   *
+   *    `af_{cjk,latin,...}_hints_compute_segments' are the functions to
+   *    find segments in an outline.
+   *
+   *    A segment is a series of at least two consecutive points that are
+   *    approximately aligned along a coordinate axis.  The analysis to do
+   *    so is specific to a writing system.
+   *
+   *
+   *  Edges
+   *
+   *    `af_{cjk,latin,...}_hints_compute_edges' are the functions to find
+   *    edges.
+   *
+   *    As soon as segments are defined, the auto-hinter groups them into
+   *    edges.  An edge corresponds to a single position on the main
+   *    dimension that collects one or more segments (allowing for a small
+   *    threshold).
+   *
+   *    As an example, the `latin' writing system first tries to grid-fit
+   *    edges, then to align segments on the edges unless it detects that
+   *    they form a serif.

+   *
+   *    Stems are detected by `af_{cjk,latin,...}_hint_edges'.
+   *
+   *    Segments need to be `linked' to other ones in order to detect stems.

+   *    vocabulary from the TrueType specification, stem segments form a
+   *    `black distance'.
+   *
+   *    In the above ASCII drawing, the horizontal segments are BC, DE, and
+   *    FG; the vertical segments are AB, CD, EF, and GH.
+   *
+   *    Each segment has at most one `best' candidate to form a black
+   *    distance, or no candidate at all.  Notice that two distinct segments
+   *    can have the same candidate, which frequently means a serif.
+   *
+   *    A stem is recognized by the following condition:
+   *
+   *      best segment_1 = segment_2 && best segment_2 = segment_1
+   *
+   *    The best candidate is stored in field `link' in structure
+   *    `AF_Segment'.
+   *
+   *    In the above ASCII drawing, the best candidate for both AB and CD is
+   *    GH, while the best candidate for GH is AB.  Similarly, the best
+   *    candidate for EF and GH is AB, while the best candidate for AB is
+   *    GH.
+   *
+   *    The detection and handling of stems is dependent on the writing
+   *    system.
+   *
+   *
+   *  Serifs
+   *
+   *    Serifs are detected by `af_{cjk,latin,...}_hint_edges'.
+   *
+   *    In comparison to a stem, a serif (as handled by the auto-hinter
+   *    module that takes care of the `latin' writing system) has
+   *
+   *      best segment_1 = segment_2 && best segment_2 != segment_1
+   *
+   *    where segment_1 corresponds to the serif segment (CD and EF in the
+   *    above ASCII drawing).
+   *
+   *    The best candidate is stored in field `serif' in structure
+   *    `AF_Segment' (and `link' is set to NULL).
+   *
+   *
+   *  Touched points
+   *
+   *    A point is called `touched' if it has been processed somehow by the
+   *    auto-hinter.  It basically means that it shouldn't be moved again
+   *    (or moved only under certain constraints to preserve the already
+   *    applied processing).
+   *
+   *
+   *  Flat and round segments
+   *
+   *    Segments are `round' or `flat', depending on the series of points
+   *    that define them.  A segment is round if the next and previous point
+   *    of an extremum (which can be either a single point or sequence of
+   *    points) are both conic or cubic control points.  Otherwise, a
+   *    segment with an extremum is flat.
+   *
+   *
+   *  Strong Points
+   *
+   *    Experience has shown that points not part of an edge need to be
+   *    interpolated linearly between their two closest edges, even if these
+   *    are not part of the contour of those particular points.  Typical
+   *    candidates for this are
+   *
+   *    - angle points (i.e., points where the `in' and `out' direction
+   *      differ greatly)
+   *
+   *    - inflection points (i.e., where the `in' and `out' angles are the
+   *      same, but the curvature changes sign) [currently, such points
+   *      aren't handled specially in the auto-hinter]
+   *
+   *    `af_glyph_hints_align_strong_points' is the function that takes
+   *    care of such situations; it is equivalent to the TrueType `IP'
+   *    hinting instruction.
+   *
+   *
+   *  Weak Points
+   *
+   *    Other points in the outline must be interpolated using the
+   *    coordinates of their previous and next unfitted contour neighbours.
+   *    These are called `weak points' and are touched by the function
+   *    `af_glyph_hints_align_weak_points', equivalent to the TrueType `IUP'
+   *    hinting instruction.  Typical candidates are control points and
+   *    points on the contour without a major direction.
+   *
+   *    The major effect is to reduce possible distortion caused by
+   *    alignment of edges and strong points, thus weak points are processed
+   *    after strong points.

+     * agnostic of OpenType features after the feature analysis has been
+     * completed: The engine then simply receives a glyph index and returns a
+     * hinted and usually rendered glyph.
+     *
+     * Consider the superscript feature of font `pala.ttf': Some of the
+     * glyphs are `real', this is, they have a zero vertical offset, but
+     * most of them are small caps glyphs shifted up to the superscript
+     * position (this is, the `sups' feature is present in both the GSUB and
+     * GPOS tables).  The code for blue zones computation actually uses a
+     * feature's y offset so that the `real' glyphs get correct hints.  But
+     * later on it is impossible to decide whether a glyph index belongs to,
+     * say, the small caps or superscript feature.
+     *
+     * For this reason, we don't assign a style to a glyph if the current
+     * feature covers the glyph in both the GSUB and the GPOS tables.  This
+     * is quite a broad condition, assuming that
+     *
+     *   (a) glyphs that get used in multiple features are present in a
+     *       feature without vertical shift,
+     *
+     * and
+     *
+     *   (b) a feature's GPOS data really moves the glyph vertically.
+     *
+     * Not fulfilling condition (a) makes a font larger; it would also
+     * reduce the number of glyphs that could be addressed directly without
+     * using OpenType features, so this assumption is rather strong.
+     *
+     * Condition (b) is much weaker, and there might be glyphs which get
+     * missed.  However, the OpenType features we are going to handle are
+     * primarily located in GSUB, and HarfBuzz doesn't provide an API to
+     * directly get the necessary information from the GPOS table.  A
+     * possible solution might be to directly parse the GPOS table to find
+     * out whether a glyph gets shifted vertically, but this is something I
+     * would like to avoid if not really necessary.
+     *
+     * Note that we don't follow this logic for the default coverage.
+     * Complex scripts like Devanagari have mandatory GPOS features to
+     * position many glyph elements, using mark-to-base or mark-to-ligature
+     * tables; the number of glyphs missed due to condition (b) would be far
+     * too large.

+   *  Usually, a font contains more glyphs than can be addressed by its
+   *  character map.
+   *
+   *  In the PostScript font world, encoding vectors specific to a given
+   *  task are used to select such glyphs, and these glyphs can be often
+   *  recognized by having a suffix in its glyph names.  For example, a
+   *  superscript glyph `A' might be called `A.sup'.  Unfortunately, this
+   *  naming scheme is not standardized and thus unusable for us.
+   *
+   *  In the OpenType world, a better solution was invented, namely
+   *  `features', which cleanly separate a character's input encoding from
+   *  the corresponding glyph's appearance, and which don't use glyph names
+   *  at all.  For our purposes, and slightly generalized, an OpenType
+   *  feature is a name of a mapping that maps character codes to
+   *  non-standard glyph indices (features get used for other things also).
+   *  For example, the `sups' feature provides superscript glyphs, thus
+   *  mapping character codes like `A' or `B' to superscript glyph
+   *  representation forms.  How this mapping happens is completely
+   *  uninteresting to us.
+   *
+   *  For the auto-hinter, a `coverage' represents all glyphs of an OpenType
+   *  feature collected in a set (as listed below) that can be hinted
+   *  together.  To continue the above example, superscript glyphs must not
+   *  be hinted together with normal glyphs because the blue zones
+   *  completely differ.
+   *
+   *  Note that FreeType itself doesn't compute coverages; it only provides
+   *  the glyphs addressable by the default Unicode character map.  Instead,
+   *  we use the HarfBuzz library (if available), which has many functions
+   *  exactly for this purpose.
+   *
+   *  AF_COVERAGE_DEFAULT is special: It should cover everything that isn't
+   *  listed separately (including the glyphs addressable by the character
+   *  map).  In case HarfBuzz isn't available, it exactly covers the glyphs
+   *  addressable by the character map.

+    Notes
+
+    Mac suitcase files can (and often do!) contain multiple fonts.  To
+    support this I use the face_index argument of FT_(Open|New)_Face()
+    functions, and pretend the suitcase file is a collection.
+
+    Warning: fbit and NFNT bitmap resources are not supported yet.  In old
+    sfnt fonts, bitmap glyph data for each size is stored in each `NFNT'
+    resources instead of the `bdat' table in the sfnt resource.  Therefore,
+    face->num_fixed_sizes is set to 0, because bitmap data in `NFNT'
+    resource is unavailable at present.
+
+    The Mac FOND support works roughly like this:
+
+    - Check whether the offered stream points to a Mac suitcase file.  This
+      is done by checking the file type: it has to be 'FFIL' or 'tfil'.  The
+      stream that gets passed to our init_face() routine is a stdio stream,
+      which isn't usable for us, since the FOND resources live in the
+      resource fork.  So we just grab the stream->pathname field.
+
+    - Read the FOND resource into memory, then check whether there is a
+      TrueType font and/or(!) a Type 1 font available.
+
+    - If there is a Type 1 font available (as a separate `LWFN' file), read
+      its data into memory, massage it slightly so it becomes PFB data, wrap
+      it into a memory stream, load the Type 1 driver and delegate the rest
+      of the work to it by calling FT_Open_Face().  (XXX TODO: after this
+      has been done, the kerning data from the FOND resource should be
+      appended to the face: On the Mac there are usually no AFM files
+      available.  However, this is tricky since we need to map Mac char
+      codes to ps glyph names to glyph ID's...)
+
+    - If there is a TrueType font (an `sfnt' resource), read it into memory,
+      wrap it into a memory stream, load the TrueType driver and delegate
+      the rest of the work to it, by calling FT_Open_Face().
+
+    - Some suitcase fonts (notably Onyx) might point the `LWFN' file to
+      itself, even though it doesn't contains `POST' resources.  To handle
+      this special case without opening the file an extra time, we just
+      ignore errors from the `LWFN' and fallback to the `sfnt' if both are
+      available.

+
+Introduction
+************
+
+BDF (Bitmap Distribution Format) is a bitmap font format defined by Adobe,
+which is intended to be easily understood by both humans and computers.
+This code implements a BDF driver for the FreeType library, following the
+Adobe Specification V 2.2.  The specification of the BDF font format is
+available from Adobe's web site:
+
+  https://www.adobe.com/content/dam/acom/en/devnet/font/pdfs/5005.BDF_Spec.pdf
+
+Many good bitmap fonts in bdf format come with XFree86 (www.XFree86.org).
+They do not define vertical metrics, because the X Consortium BDF
+specification has removed them.
+
+
+Encodings
+*********
+
+The variety of encodings that accompanies bdf fonts appears to encompass the
+small set defined in freetype.h.  On the other hand, two properties that
+specify encoding and registry are usually defined in bdf fonts.
+
+I decided to make these two properties directly accessible, leaving to the
+client application the work of interpreting them.  For instance:
+
+
+  #include FT_INTERNAL_BDF_TYPES_H
+
+  FT_Face          face;
+  BDF_Public_Face  bdfface;
+
+
+  FT_New_Face( library, ..., &face );
+
+  bdfface = (BDF_Public_Face)face;
+
+  if ( ( bdfface->charset_registry == "ISO10646" ) &&
+       ( bdfface->charset_encoding == "1" )        )
+    [..]
+
+
+Thus the driver always exports `ft_encoding_none' as face->charmap.encoding.
+FT_Get_Char_Index's behavior is unmodified, that is, it converts the ULong
+value given as argument into the corresponding glyph number.
+
+If the two properties are not available, Adobe Standard Encoding should be
+assumed.
+
+
+Anti-Aliased Bitmaps
+********************
+
+The driver supports an extension to the BDF format as used in Mark Leisher's
+xmbdfed bitmap font editor.  Microsoft's SBIT tool expects bitmap fonts in
+that format for adding anti-aliased them to TrueType fonts.  It introduces a
+fourth field to the `SIZE' keyword which gives the bpp value (bits per
+pixel) of the glyph data in the font.  Possible values are 1 (the default),
+2 (four gray levels), 4 (16 gray levels), and 8 (256 gray levels).  The
+driver returns either a bitmap with 1 bit per pixel or a pixmap with 8bits
+per pixel (using 4, 16, and 256 gray levels, respectively).
+
+
+Known problems
+**************
+
+- A font is entirely loaded into memory.  Obviously, this is not the Right
+  Thing(TM).  If you have big fonts I suggest you convert them into PCF
+  format (using the bdftopcf utility): the PCF font drive of FreeType can
+  perform incremental glyph loading.
+
+When I have some time, I will implement on-demand glyph parsing.
+
+- Except for encodings properties, client applications have no visibility of
+  the PCF_Face object.  This means that applications cannot directly access
+  font tables and must trust FreeType.
+
+- Currently, glyph names are ignored.
+
+  I plan to give full visibility of the BDF_Face object in an upcoming
+  revision of the driver, thus implementing also glyph names.
+
+- As I have never seen a BDF font that defines vertical metrics, vertical
+  metrics are (parsed and) discarded.  If you own a BDF font that defines
+  vertical metrics, please let me know (I will implement them in 5-10
+  minutes).

+  /*
+   *
+   *  FTC_GCache is an _abstract_ cache object optimized to store glyph
+   *  data.  It works as follows:
+   *
+   *   - It manages FTC_GNode objects. Each one of them can hold one or more
+   *     glyph `items'.  Item types are not specified in the FTC_GCache but
+   *     in classes that extend it.
+   *
+   *   - Glyph attributes, like face ID, character size, render mode, etc.,
+   *     can be grouped into abstract `glyph families'.  This avoids storing
+   *     the attributes within the FTC_GCache, since it is likely that many
+   *     FTC_GNodes will belong to the same family in typical uses.
+   *
+   *   - Each FTC_GNode is thus an FTC_Node with two additional fields:
+   *
+   *       * gindex: A glyph index, or the first index in a glyph range.
+   *       * family: A pointer to a glyph `family'.
+   *
+   *   - Family types are not fully specific in the FTC_Family type, but
+   *     by classes that extend it.
+   *
+   *  Note that both FTC_ImageCache and FTC_SBitCache extend FTC_GCache.
+   *  They share an FTC_Family sub-class called FTC_BasicFamily which is
+   *  used to store the following data: face ID, pixel/point sizes, load
+   *  flags.  For more details see the file `src/cache/ftcbasic.c'.
+   *
+   *  Client applications can extend FTC_GNode with their own FTC_GNode
+   *  and FTC_Family sub-classes to implement more complex caches (e.g.,
+   *  handling automatic synthesis, like obliquing & emboldening, colored
+   *  glyphs, etc.).
+   *
+   *  See also the FTC_ICache & FTC_SCache classes in `ftcimage.h' and
+   *  `ftcsbits.h', which both extend FTC_GCache with additional
+   *  optimizations.
+   *
+   *  A typical FTC_GCache implementation must provide at least the
+   *  following:
+   *
+   *  - FTC_GNode sub-class, e.g. MyNode, with relevant methods:
+   *        my_node_new            (must call FTC_GNode_Init)
+   *        my_node_free           (must call FTC_GNode_Done)
+   *        my_node_compare        (must call FTC_GNode_Compare)
+   *        my_node_remove_faceid  (must call ftc_gnode_unselect in case
+   *                                of match)
+   *
+   *  - FTC_Family sub-class, e.g. MyFamily, with relevant methods:
+   *        my_family_compare
+   *        my_family_init
+   *        my_family_reset (optional)
+   *        my_family_done
+   *
+   *  - FTC_GQuery sub-class, e.g. MyQuery, to hold cache-specific query
+   *    data.
+   *
+   *  - Constant structures for a FTC_GNodeClass.
+   *
+   *  - MyCacheNew() can be implemented easily as a call to the convenience
+   *    function FTC_GCache_New.
+   *
+   *  - MyCacheLookup with a call to FTC_GCache_Lookup.  This function will
+   *    automatically:
+   *
+   *    - Search for the corresponding family in the cache, or create
+   *      a new one if necessary.  Put it in FTC_GQUERY(myquery).family
+   *
+   *    - Call FTC_Cache_Lookup.
+   *
+   *    If it returns NULL, you should create a new node, then call
+   *    ftc_cache_add as usual.

+       *  a non-zero error code only when we are out of memory (OOM).

+       *  an OOM errors occur.
+       *
+       *  However, we need to `lock' the node before this operation to
+       *  prevent it from being flushed within the loop.
+       *
+       *  When we exit the loop, we unlock the node, then check the `error'
+       *  variable.  If it is non-zero, this means that the cache was
+       *  completely flushed and that no usable memory was found to load
+       *  the bitmap.
+       *
+       *  We then prefer to return a value of 0 (i.e., NO MATCH).  This
+       *  ensures that the caller will try to allocate a new node.
+       *  This operation consequently _fail_ and the lookup function
+       *  returns the appropriate OOM error code.
+       *
+       *  Note that `buffer == NULL && width == 255' is a hack used to

+gxvalid: TrueType GX validator
+==============================
+
+
+1. What is this
+---------------
+
+  `gxvalid' is a module to  validate TrueType GX tables: a collection of
+  additional tables  in TrueType  font which are  used by  `QuickDraw GX
+  Text',  Apple Advanced  Typography  (AAT).  In  addition, gxvalid  can
+  validates `kern'  tables which have  been extended for AAT.   Like the
+  otvalid  module,   gxvalid  uses   FreeType  2's  validator  framework
+  (ftvalid).
+
+  You can link gxvalid with your program; before running your own layout
+  engine, gxvalid validates a font  file.  As the result, you can remove
+  error-checking code  from the layout  engine.  It is also  possible to
+  use  gxvalid  as a  stand-alone  font  validator;  the `ftvalid'  test
+  program  included  in the  ft2demo  bundle  calls gxvalid  internally.
+  A stand-alone font validator may be useful for font developers.
+
+  This documents documents the following issues.
+
+  - supported TrueType GX tables
+  - fundamental validation limitations
+  - permissive error handling of broken GX tables
+  - `kern' table issue.
+
+
+2. Supported tables
+-------------------
+
+  The following GX tables are currently supported.
+
+    bsln
+    feat
+    just
+    kern(*)
+    lcar
+    mort
+    morx
+    opbd
+    prop
+    trak
+
+  The following GX tables are currently unsupported.
+
+    cvar
+    fdsc
+    fmtx
+    fvar
+    gvar
+    Zapf
+
+  The following GX tables won't be supported.
+
+    acnt(**)
+    hsty(***)
+
+  The following undocumented tables in TrueType fonts designed for Apple
+  platform aren't handled either.
+
+    addg
+    CVTM
+    TPNM
+    umif
+
+
+  *)   The `kern'  validator handles both  the classic and the  new kern
+       formats;  the former  is supported  on both  Microsoft  and Apple
+       platforms, while the latter is supported on Apple platforms.
+
+  **)  `acnt' tables are not supported by currently available Apple font
+       tools.
+
+  ***) There  is  one more  Apple  extension,  `hsty',  but  it  is  for
+       Newton-OS, not GX  (Newton-OS is a platform by  Apple, but it can
+       use  sfnt- housed bitmap  fonts only).   Therefore, it  should be
+       excluded  from  `Apple  platform'  in the  context  of  TrueType.
+       gxvalid ignores it as Apple font tools do so.
+
+
+  We have  checked 183  fonts bundled with  MacOS 9.1, MacOS  9.2, MacOS
+  10.0, MacOS X 10.1, MSIE  for MacOS, and AppleWorks 6.0.  In addition,
+  we have  checked 67 Dynalab fonts  (designed for MacOS)  and 189 Ricoh
+  fonts (designed for Windows and  MacOS dual platforms).  The number of
+  fonts including TrueType GX tables are as follows.
+
+    bsln:  76
+    feat: 191
+    just:  84
+    kern:  59
+    lcar:   4
+    mort: 326
+    morx:  19
+    opbd:   4
+    prop: 114
+    trak:  16
+
+  Dynalab  and Ricoh fonts  don't have  GX tables  except of  `feat' and
+  `mort'.
+
+
+3. Fundamental validation limitations
+-------------------------------------
+
+  TrueType  GX  provides  layout   information  to  libraries  for  font
+  rasterizers  and text layout.   gxvalid can  check whether  the layout
+  data in  a font is conformant  to the TrueType GX  format specified by
+  Apple.  But gxvalid cannot check  a how QuickDraw GX/AAT renderer uses
+  the stored information.
+
+  3-1. Validation of State Machine activity
+  -----------------------------------------
+
+    QuickDraw GX/AAT uses a `State Machine' to provide `stateful' layout
+    features,  and TrueType GX  stores the  state transition  diagram of
+    this `State  Machine' in a  `StateTable' data structure.   While the
+    State  Machine receives  a series  of glyph  IDs, the  State Machine
+    starts with `start  of text' state, walks around  various states and
+    generates various  layout information  to the  renderer, and finally
+    reaches the `end of text' state.
+
+    gxvalid can check essential errors like:
+
+      - possibility of state transitions to undefined states
+      - existence of glyph  IDs that the State Machine  doesn't know how
+        to handle
+      - the  State Machine  cannot compute  the layout  information from
+        given diagram
+
+    These errors  can be  checked within finite  steps, and  without the
+    State Machine itself, because these are `expression' errors of state
+    transition diagram.
+
+    There  is no  limitation  about  how long  the  State Machine  walks
+    around,  so validation  of  the algorithm  in  the state  transition
+    diagram requires infinite  steps, even if we had  a State Machine in
+    gxvalid.   Therefore, the  following errors  and problems  cannot be
+    checked.
+
+      - existence of states which the State Machine never transits to
+      - the  possibility that the  State Machine  never reaches  `end of
+        text'
+      - the possibility of stack underflow/overflow in the State Machine
+        (in  ligature  and  contextual  glyph substitutions,  the  State
+        Machine can store 16 glyphs onto its stack)
+
+    In addition, gxvalid doesn't check `temporary glyph IDs' used in the
+    chained State Machines  (in `mort' and `morx' tables).   If a layout
+    feature  is  implemented by  a  single  State  Machine, a  glyph  ID
+    converted by the State Machine is passed to the glyph renderer, thus
+    it  should not  point to  an undefined  glyph ID.   But if  a layout
+    feature is implemented by  chained State Machines, a component State
+    Machine  (if it  is  not the  final  one) is  permitted to  generate
+    undefined glyph IDs for temporary use, because it is handled by next
+    component State Machine and not  by the glyph renderer.  To validate
+    such temporary glyph IDs, gxvalid must stack all undefined glyph IDs
+    which  can occur in  the output  of the  previous State  Machine and
+    search  them in  the  `ClassTable' structure  of  the current  State
+    Machine.  It is too complex to  list all possible glyph IDs from the
+    StateTable, especially from a ligature substitution table.
+
+  3-2. Validation of relationship between multiple layout features
+  ----------------------------------------------------------------
+
+    gxvalid does  not validate the relationship  between multiple layout
+    features at all.
+
+    If  multiple layout  features  are defined  in  TrueType GX  tables,
+    possible  interactions,  overrides,  and  conflicts  between  layout
+    features are implicitly  given in the font too.   For example, there
+    are several predefined spacing control features:
+
+      - Text Spacing          (Proportional/Monospace/Half-width/Normal)
+      - Number Spacing        (Monospaced-numbers/Proportional-numbers)
+      - Kana Spacing          (Full-width/Proportional)
+      - Ideographic Spacing   (Full-width/Proportional)
+      - CJK Roman Spacing     (Half-width/Proportional/Default-roman
+                               /Full-width-roman/Proportional)
+
+    If all  layout features are  independently managed, we  can activate
+    inconsistent  typographic rules  like  `Text Spacing=Monospace'  and
+    `Ideographic Spacing=Proportional' at the same time.
+
+    The combinations  of layout features  is managed by a  32bit integer
+    (one bit each for selector  setting), so we can define relationships
+    between  up  to 32  features,  theoretically.   But  if one  feature
+    setting  affects  another   feature  setting,  we  need  typographic
+    priority  rules to  validate the  relationship.   Unfortunately, the
+    TrueType GX format specification does not give such information even
+    for predefined features.
+
+
+4. Permissive error handling of broken GX tables
+------------------------------------------------
+
+  When  Apple's font  rendering system  finds an  inconsistency,  like a
+  specification  violation or  an  unspecified value  in  a TrueType  GX
+  table, it does not always  return error.  In most cases, the rendering
+  engine silently  ignores such wrong  values or even whole  tables.  In
+  fact, MacOS is shipped with  fonts including broken GX/AAT tables, but
+  no harmful  effects due to  `officially broken' fonts are  observed by
+  end-users.
+
+  gxvalid  is designed  to continue  the validation  process as  long as
+  possible.  When gxvalid find wrong  values, gxvalid warns it at least,
+  and takes  a fallback procedure  if possible.  The  fallback procedure
+  depends on the debug level.
+
+  We used the following three tools to investigate Apple's error handling.
+
+    - FontValidator  (for MacOS 8.5 - 9.2)  resource fork font
+    - ftxvalidator   (for MacOS X 10.1 -)   dfont or naked-sfnt
+    - ftxdumperfuser (for MacOS X 10.1 -)   dfont or naked-sfnt
+
+  However, all tests were done on a PowerPC based Macintosh; at present,
+  we have not checked those tools on a m68k-based Macintosh.
+
+  In total, we checked 183 fonts  bundled to MacOS 9.1, MacOS 9.2, MacOS
+  10.0, MacOS X  10.1, MSIE for MacOS, and  AppleWorks 6.0.  These fonts
+  are distributed  officially, but many broken GX/AAT  tables were found
+  by Apple's font tools.  In the following, we list typical violation of
+  the GX specification, in fonts officially distributed with those Apple
+  systems.
+
+  4-1. broken BinSrchHeader (19/183)
+  ----------------------------------
+
+    `BinSrchHeader' is  a header of a  data array for  m68k platforms to
+    access memory efficiently.  Although  there are only two independent
+    parameters  for real  (`unitSize' and  `nUnits'),  BinSrchHeader has
+    three additional parameters which  can be calculated from `unitSize'
+    and  `nUnits',  for  fast  setup.   Apple  font  tools  ignore  them
+    silently, so gxvalid warns if it finds and inconsistency, and always
+    continues  validation.    The  additional  parameters   are  ignored
+    regardless of the consistency.
+
+      19  fonts include  such  inconsistencies; all  breaks  are in  the
+      BinSrchHeader structure of the `kern' table.
+
+  4-2. too-short LookupTable (5/183)
+  ----------------------------------
+
+    LookupTable format 0  is a simple array to get a  value from a given
+    GID (glyph  ID); the index of  this array is a  GID too.  Therefore,
+    the length  of the array is expected  to be same as  the maximum GID
+    value defined  in the `maxp' table,  but there are  some fonts whose
+    LookupTable format 0 is too  short to cover all GIDs.  FontValidator
+    ignores  this error silently,  ftxvalidator and  ftxdumperfuser both
+    warn and continue.  Similar problems are found in format 3 subtables
+    of `kern'.  gxvalid  warns always and abort if  the validation level
+    is set to FT_VALIDATE_PARANOID.
+
+      5 fonts include too-short kern format 0 subtables.
+      1 font includes too-short kern format 3 subtable.
+
+  4-3. broken LookupTable format 2 (1/183)
+  ----------------------------------------
+
+    LookupTable  format  2,  subformat  4  covers the  GID  space  by  a
+    collection  of  segments which  are  specified  by `firstGlyph'  and
+    `lastGlyph'.   Some  fonts  store  `firstGlyph' and  `lastGlyph'  in
+    reverse order,  so the segment specification is  broken.  Apple font
+    tools ignore this error silently;  a broken segment is ignored as if
+    it  did not  exist.   gxvalid  warns and  normalize  the segment  at
+    FT_VALIDATE_DEFAULT, or ignore  the segment at FT_VALIDATE_TIGHT, or
+    abort at FT_VALIDATE_PARANOID.
+
+      1 font includes broken LookupTable format 2, in the `just' table.
+
+    *) It seems  that all fonts manufactured by  ITC for AppleWorks have
+       this error.
+
+  4-4. bad bracketing in glyph property (14/183)
+  ----------------------------------------------
+
+    GX/AAT defines a  `bracketing' property of the glyphs  in the `prop'
+    table,  to control layout  features of  strings enclosed  inside and
+    outside  of   brackets.   Some  fonts   give  inappropriate  bracket
+    properties  to glyphs.   Apple  font tools  warn  about this  error;
+    gxvalid warns too and aborts at FT_VALIDATE_PARANOID.
+
+      14 fonts include wrong bracket properties.
+
+
+  4-5. invalid feature number (117/183)
+  -------------------------------------
+
+    The GX/AAT  extension can  include 255 different  layout features,
+    but    popular    layout     features    are    predefined    (see
+    https://developer.apple.com/fonts/TrueType-Reference-Manual/RM09/AppendixF.html).
+    Some fonts include feature numbers which are incompatible with the
+    predefined feature registry.
+
+    In our survey, there are 140 fonts including `feat' table.
+
+    a) 67 fonts use a feature number which should not be used.
+    b) 117 fonts set the wrong feature range (nSetting).  This is mostly
+       found in the `mort' and `morx' tables.
+
+    Apple  font tools give  no warning,  although they  cannot recognize
+    what  the feature  is.   At FT_VALIDATE_DEFAULT,  gxvalid warns  but
+    continues in both cases (a, b).  At FT_VALIDATE_TIGHT, gxvalid warns
+    and aborts for (a), but continues for (b).  At FT_VALIDATE_PARANOID,
+    gxvalid warns and aborts in both cases (a, b).
+
+  4-6. invalid prop version (10/183)
+  ----------------------------------
+
+    As most TrueType GX tables, the `prop' table must start with a 32bit
+    version identifier: 0x00010000,  0x00020000 or 0x00030000.  But some
+    fonts  store nonsense binary  data instead.   When Apple  font tools
+    find them, they abort the processing immediately, and the data which
+    follows is unhandled.  gxvalid does the same.
+
+      10 fonts include broken `prop' version.
+
+    All  of these  fonts are  classic  TrueType fonts  for the  Japanese
+    script, manufactured by Apple.
+
+  4-7. unknown resource name (2/183)
+  ------------------------------------
+
+    NOTE: THIS IS NOT A TRUETYPE GX ERROR.
+
+    If  a TrueType  font is  stored  in the  resource fork  or in  dfont
+    format, the data must be tagged as `sfnt' in the resource fork index
+    to invoke TrueType font handler for the data.  But the TrueType font
+    data  in   `Keyboard.dfont'  is  tagged   as  `kbd',  and   that  in
+    `LastResort.dfont' is tagged as  `lst'.  Apple font tools can detect
+    that the data is in  TrueType format and successfully validate them.
+    Maybe  this is possible  because they  are known  to be  dfont.  The
+    current  implementation  of the  resource  fork  driver of  FreeType
+    cannot do that, thus gxvalid cannot validate them.
+
+      2 fonts use an unknown tag for the TrueType font resource.
+
+5. `kern' table issues
+----------------------
+
+  In common terminology of TrueType, `kern' is classified as a basic and
+  platform-independent table.  But there are Apple extensions of `kern',
+  and  there is  an  extension which  requires  a GX  state machine  for
+  contextual kerning.   Therefore, gxvalid includes  a special validator
+  for  `kern' tables.   Unfortunately, there  is no  exact  algorithm to
+  check Apple's extension, so  gxvalid includes a heuristic algorithm to
+  find  the proper validation  routines for  all possible  data formats,
+  including    the   data    format   for    Microsoft.     By   calling
+  classic_kern_validate() instead of gxv_validate(), you can specify the
+  `kern' format  explicitly.  However, current  FreeType2 uses Microsoft
+  `kern' format  only, others  are ignored (and  should be handled  in a
+  library one level higher than FreeType).
+
+  5-1. History
+  ------------
+
+    The original  16bit version of `kern'  was designed by  Apple in the
+    pre-GX  era, and  it was  also approved  by  Microsoft.  Afterwards,
+    Apple designed a  new 32bit version of the  `kern' table.  According
+    to  the documentation, the  difference between  the 16bit  and 32bit
+    version is only the size of  variables in the `kern' header.  In the
+    following,  we call  the original  16bit version  as  `classic', and
+    32bit version as `new'.
+
+  5-2. Versions and dialects which should be differentiated
+  ---------------------------------------------------------
+
+    The `kern' table  consists of a table header  and several subtables.
+    The version number  which identifies a `classic' or  a `new' version
+    is  explicitly   written  in  the   table  header,  but   there  are
+    undocumented  differences between  Microsoft's and  Apple's formats.
+    It is  called a `dialect' in  the following.  There  are three cases
+    which  should  be  handled:   the  new  Apple-dialect,  the  classic
+    Apple-dialect,  and the classic  Microsoft-dialect.  An  analysis of
+    the formats and the auto detection algorithm of gxvalid is described
+    in the following.
+
+    5-2-1. Version detection: classic and new kern
+    ----------------------------------------------
+
+      According  to Apple  TrueType  specification, there  are only  two
+      differences between the classic and the new:
+
+        - The `kern' table header starts with the version number.
+          The classic version starts with 0x0000 (16bit),
+          the new version starts with 0x00010000 (32bit).
+
+        - In the  `kern' table header,  the number of  subtables follows
+          the version number.
+          In the classic version, it is stored as a 16bit value.
+          In the new version, it is stored as a 32bit value.
+
+      From Apple font tool's output (DumpKERN is also tested in addition
+      to  the  three  Apple  font  tools in  above),  there  is  another
+      undocumented difference.  In the  new version, the subtable header
+      includes a 16bit variable  named `tupleIndex' which does not exist
+      in the classic version.
+
+      The new version  can store all subtable formats (0,  1, 2, and 3),
+      but the Apple TrueType specification does not mention the subtable
+      formats available in the classic version.
+
+    5-2-2. Available subtable formats in classic version
+    ----------------------------------------------------
+
+      Although the  Apple TrueType  specification recommends to  use the
+      classic version in  the case if the font is  designed for both the
+      Apple and Microsoft platforms,  it does not document the available
+      subtable formats in the classic version.
+
+      According  to the Microsoft  TrueType specification,  the subtable
+      format  assured for  Windows  and OS/2  support  is only  subtable
+      format  0.  The  Microsoft TrueType  specification  also describes
+      subtable format  2, but does  not mention which  platforms support
+      it.  Subtable formats 1, 3,  and higher are documented as reserved
+      for future use.  Therefore, the classic version can store subtable
+      formats 0 and 2, at least.  `ttfdump.exe', a font tool provided by
+      Microsoft,  ignores the  subtable format  written in  the subtable
+      header, and parses the table as if all subtables are in format 0.
+
+      `kern'  subtable format  1  uses  a StateTable,  so  it cannot  be
+      utilized without a GX  State Machine.  Therefore, it is reasonable
+      to assume  that format 1 (and  3) were introduced  after Apple had
+      introduced GX and moved to the new 32bit version.
+
+    5-2-3. Apple and Microsoft dialects
+    -----------------------------------
+
+      The  `kern' subtable  has  a 16bit  `coverage'  field to  describe
+      kerning attributes, but bit interpretations by Apple and Microsoft
+      are different:  For example, Apple  uses bits 0-7 to  identify the
+      subtable, while Microsoft uses bits 8-15.
+
+      In  addition, due  to the  output of  DumpKERN  and FontValidator,
+      Apple's bit interpretations of coverage in classic and new version
+      are  incompatible also.   In  summary, there  are three  dialects:
+      classic Apple  dialect, classic  Microsoft dialect, and  new Apple
+      dialect.  The classic Microsoft  dialect and the new Apple dialect
+      are documented  by each vendors' TrueType  font specification, but
+      the documentation for classic Apple dialect is not available.
+
+      For example,  in the  new Apple dialect,  bit 15 is  documented as
+      `set to  1 if  the kerning  is vertical'.  On  the other  hand, in
+      classic Microsoft dialect, bit 1 is documented as `set to 1 if the
+      kerning  is  horizontal'.   From   the  outputs  of  DumpKERN  and
+      FontValidator, classic  Apple dialect recognizes  15 as `set  to 1
+      when  the kerning  is horizontal'.   From the  results  of similar
+      experiments, classic Apple dialect  seems to be the Endian reverse
+      of the classic Microsoft dialect.
+
+      As a  conclusion it must be  noted that no font  tool can identify
+      classic Apple dialect or classic Microsoft dialect automatically.
+
+    5-2-4. gxvalid auto dialect detection algorithm
+    -----------------------------------------------
+
+      The first 16  bits of the `kern' table are  enough to identify the
+      version:
+
+        - if  the first  16  bits are  0x0000,  the `kern'  table is  in
+          classic Apple dialect or classic Microsoft dialect
+        - if the first 16 bits are  0x0001, and next 16 bits are 0x0000,
+          the kern table is in new Apple dialect.
+
+      If the `kern'  table is a classic one,  the 16bit `coverage' field
+      is checked next.   Firstly, the coverage bits are  decoded for the
+      classic Apple dialect using the following bit masks (this is based
+      on DumpKERN output):
+
+        0x8000: 1=horizontal, 0=vertical
+        0x4000: not used
+        0x2000: 1=cross-stream, 0=normal
+        0x1FF0: reserved
+        0x000F: subtable format
+
+      If  any  of  reserved  bits  are  set  or  the  subtable  bits  is
+      interpreted as format 1 or 3, we take it as `impossible in classic
+      Apple dialect' and retry, using the classic Microsoft dialect.
+
+        The most popular coverage in new Apple-dialect:         0x8000,
+        The most popular coverage in classic Apple-dialect:     0x0000,
+        The most popular coverage in classic Microsoft dialect: 0x0001.
+
+  5-3. Tested fonts
+  -----------------
+
+    We checked  59 fonts  bundled with MacOS  and 38 fonts  bundled with
+    Windows, where all font include a `kern' table.
+
+      - fonts bundled with MacOS
+        * new Apple dialect
+          format 0: 18
+          format 2:  1
+          format 3:  1
+        * classic Apple dialect
+          format 0: 14
+        * classic Microsoft dialect
+          format 0: 15
+
+      - fonts bundled with Windows
+        * classic Microsoft dialect
+          format 0: 38
+
+    It looks strange that classic Microsoft-dialect fonts are bundled to
+    MacOS: they come from MSIE for MacOS, except of MarkerFelt.dfont.

+  ---------------
+
+  Some parts of gxvalid are  derived from both the `gxlayout' module and
+  the `otvalid'  module.  Development of  gxlayout was supported  by the
+  Information-technology Promotion Agency(IPA), Japan.

+   Notes beyond the 1.93a appnote.txt:
+
+   1. Distance pointers never point before the beginning of the output
+      stream.
+   2. Distance pointers can point back across blocks, up to 32k away.
+   3. There is an implied maximum of 7 bits for the bit length table and
+      15 bits for the actual data.
+   4. If only one code exists, then it is encoded using one bit.  (Zero
+      would be more efficient, but perhaps a little confusing.)  If two
+      codes exist, they are coded using one bit each (0 and 1).
+   5. There is no way of sending zero distance codes--a dummy must be
+      sent if there are none.  (History: a pre 2.0 version of PKZIP would
+      store blocks with no distance codes, but this was discovered to be
+      too harsh a criterion.)  Valid only for 1.93a.  2.04c does allow
+      zero distance codes, which is sent as one code of zero bits in
+      length.
+   6. There are up to 286 literal/length codes.  Code 256 represents the
+      end-of-block.  Note however that the static length tree defines
+      288 codes just to fill out the Huffman codes.  Codes 286 and 287
+      cannot be used though, since there is no length base or extra bits
+      defined for them.  Similarily, there are up to 30 distance codes.
+      However, static trees define 32 codes (all 5 bits) to fill out the
+      Huffman codes, but the last two had better not show up in the data.
+   7. Unzip can check dynamic Huffman blocks for complete code sets.
+      The exception is that a single code would not be complete (see #4).
+   8. The five bits following the block type is really the number of
+      literal codes sent minus 257.
+   9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits
+      (1+6+6).  Therefore, to output three times the length, you output
+      three codes (1+1+1), whereas to output four times the same length,
+      you only need two codes (1+3).  Hmm.
+  10. In the tree reconstruction algorithm, Code = Code + Increment
+      only if BitLength(i) is not zero.  (Pretty obvious.)
+  11. Correction: 4 Bits: # of Bit Length codes - 4     (4 - 19)
+  12. Note: length code 284 can represent 227-258, but length code 285
+      really is 258.  The last length deserves its own, short code
+      since it gets used a lot in very redundant files.  The length
+      258 is special since 258 - 3 (the min match length) is 255.
+  13. The literal/length and distance code bit lengths are read as a
+      single stream of lengths.  It is possible (and advantageous) for
+      a repeat code (16, 17, or 18) to go across the boundary between
+      the two sets of lengths.

+   Huffman code decoding is performed using a multi-level table lookup.
+   The fastest way to decode is to simply build a lookup table whose
+   size is determined by the longest code.  However, the time it takes
+   to build this table can also be a factor if the data being decoded
+   is not very long.  The most common codes are necessarily the
+   shortest codes, so those codes dominate the decoding time, and hence
+   the speed.  The idea is you can have a shorter table that decodes the
+   shorter, more probable codes, and then point to subsidiary tables for
+   the longer codes.  The time it costs to decode the longer codes is
+   then traded against the time it takes to make longer tables.
+
+   This results of this trade are in the variables lbits and dbits
+   below.  lbits is the number of bits the first level table for literal/
+   length codes can decode in one step, and dbits is the same thing for
+   the distance codes.  Subsequent tables are also less than or equal to
+   those sizes.  These values may be adjusted either when all of the
+   codes are shorter than that, in which case the longest code length in
+   bits is used, or when the shortest code is *longer* than the requested
+   table size, in which case the length of the shortest code in bits is
+   used.
+
+   There are two different values for the two tables, since they code a
+   different number of possibilities each.  The literal/length table
+   codes 286 possible values, or in a flat code, a little over eight
+   bits.  The distance table codes 30 possible values, or a little less
+   than five bits, flat.  The optimum values for speed end up being
+   about one bit more than those, so lbits is 8+1 and dbits is 5+1.
+   The optimum values may differ though from machine to machine, and
+   possibly even between compilers.  Your mileage may vary.

+     The 'zlib' compression library provides in-memory compression and
+  decompression functions, including integrity checks of the uncompressed
+  data.  This version of the library supports only one compression method
+  (deflation) but other algorithms will be added later and will have the same
+  stream interface.
+
+     Compression can be done in a single step if the buffers are large
+  enough (for example if an input file is mmap'ed), or can be done by
+  repeated calls of the compression function.  In the latter case, the
+  application must provide more input and/or consume the output
+  (providing more output space) before each call.
+
+     The library also supports reading and writing files in gzip (.gz) format
+  with an interface similar to that of stdio.
+
+     The library does not install any signal handler. The decoder checks
+  the consistency of the compressed data, so the library should never
+  crash even in case of corrupted input.

+   The application must update next_in and avail_in when avail_in has
+   dropped to zero. It must update next_out and avail_out when avail_out
+   has dropped to zero. The application must initialize zalloc, zfree and
+   opaque before calling the init function. All other fields are set by the
+   compression library and must not be updated by the application.
+
+   The opaque value provided by the application will be passed as the first
+   parameter for calls of zalloc and zfree. This can be useful for custom
+   memory management. The compression library attaches no meaning to the
+   opaque value.
+
+   zalloc must return Z_NULL if there is not enough memory for the object.
+   If zlib is used in a multi-threaded application, zalloc and zfree must be
+   thread safe.
+
+   On 16-bit systems, the functions zalloc and zfree must be able to allocate
+   exactly 65536 bytes, but will not be required to allocate more than this
+   if the symbol MAXSEG_64K is defined (see zconf.h). WARNING: On MSDOS,
+   pointers returned by zalloc for objects of exactly 65536 bytes *must*
+   have their offset normalized to zero. The default allocation function
+   provided by this library ensures this (see zutil.c). To reduce memory
+   requirements and avoid any allocation of 64K objects, at the expense of
+   compression ratio, compile the library with -DMAX_WBITS=14 (see zconf.h).
+
+   The fields total_in and total_out can be used for statistics or
+   progress reports. After compression, total_in holds the total size of
+   the uncompressed data and may be saved for use in the decompressor

+    deflate compresses as much data as possible, and stops when the input
+  buffer becomes empty or the output buffer becomes full. It may introduce some
+  output latency (reading input without producing any output) except when
+  forced to flush.
+
+    The detailed semantics are as follows. deflate performs one or both of the
+  following actions:
+
+  - Compress more input starting at next_in and update next_in and avail_in
+    accordingly. If not all input can be processed (because there is not
+    enough room in the output buffer), next_in and avail_in are updated and
+    processing will resume at this point for the next call of deflate().
+
+  - Provide more output starting at next_out and update next_out and avail_out
+    accordingly. This action is forced if the parameter flush is non zero.
+    Forcing flush frequently degrades the compression ratio, so this parameter
+    should be set only when necessary (in interactive applications).
+    Some output may be provided even if flush is not set.
+
+  Before the call of deflate(), the application should ensure that at least
+  one of the actions is possible, by providing more input and/or consuming
+  more output, and updating avail_in or avail_out accordingly; avail_out
+  should never be zero before the call. The application can consume the
+  compressed output when it wants, for example when the output buffer is full
+  (avail_out == 0), or after each call of deflate(). If deflate returns Z_OK
+  and with zero avail_out, it must be called again after making room in the
+  output buffer because there might be more output pending.
+
+    If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
+  flushed to the output buffer and the output is aligned on a byte boundary, so
+  that the decompressor can get all input data available so far. (In particular
+  avail_in is zero after the call if enough output space has been provided
+  before the call.)  Flushing may degrade compression for some compression
+  algorithms and so it should be used only when necessary.
+
+    If flush is set to Z_FULL_FLUSH, all output is flushed as with
+  Z_SYNC_FLUSH, and the compression state is reset so that decompression can
+  restart from this point if previous compressed data has been damaged or if
+  random access is desired. Using Z_FULL_FLUSH too often can seriously degrade
+  the compression.
+
+    If deflate returns with avail_out == 0, this function must be called again
+  with the same value of the flush parameter and more output space (updated
+  avail_out), until the flush is complete (deflate returns with non-zero
+  avail_out).
+
+    If the parameter flush is set to Z_FINISH, pending input is processed,
+  pending output is flushed and deflate returns with Z_STREAM_END if there
+  was enough output space; if deflate returns with Z_OK, this function must be
+  called again with Z_FINISH and more output space (updated avail_out) but no
+  more input data, until it returns with Z_STREAM_END or an error. After
+  deflate has returned Z_STREAM_END, the only possible operations on the
+  stream are deflateReset or deflateEnd.
+
+    Z_FINISH can be used immediately after deflateInit if all the compression
+  is to be done in a single step. In this case, avail_out must be at least
+  0.1% larger than avail_in plus 12 bytes.  If deflate does not return
+  Z_STREAM_END, then it must be called again as described above.
+
+    deflate() sets strm->adler to the adler32 checksum of all input read
+  so far (that is, total_in bytes).
+
+    deflate() may update data_type if it can make a good guess about
+  the input data type (Z_ASCII or Z_BINARY). In doubt, the data is considered
+  binary. This field is only for information purposes and does not affect
+  the compression algorithm in any manner.
+
+    deflate() returns Z_OK if some progress has been made (more input
+  processed or more output produced), Z_STREAM_END if all input has been
+  consumed and all output has been produced (only when flush is set to
+  Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example

+
+    If the parameter flush is set to Z_SYNC_FLUSH, inflate flushes as much
+  output as possible to the output buffer. The flushing behavior of inflate is
+  not specified for values of the flush parameter other than Z_SYNC_FLUSH
+  and Z_FINISH, but the current implementation actually flushes as much output
+  as possible anyway.
+
+    inflate() should normally be called until it returns Z_STREAM_END or an
+  error. However if all decompression is to be performed in a single step
+  (a single call of inflate), the parameter flush should be set to
+  Z_FINISH. In this case all pending input is processed and all pending
+  output is flushed; avail_out must be large enough to hold all the
+  uncompressed data. (The size of the uncompressed data may have been saved
+  by the compressor for this purpose.) The next operation on this stream must

+
+     The method parameter is the compression method. It must be Z_DEFLATED in
+   this version of the library.
+
+     The windowBits parameter is the base two logarithm of the window size
+   (the size of the history buffer).  It should be in the range 8..15 for this
+   version of the library. Larger values of this parameter result in better
+   compression at the expense of memory usage. The default value is 15 if
+   deflateInit is used instead.
+
+     The memLevel parameter specifies how much memory should be allocated
+   for the internal compression state. memLevel=1 uses minimum memory but
+   is slow and reduces compression ratio; memLevel=9 uses maximum memory
+   for optimal speed. The default value is 8. See zconf.h for total memory
+   usage as a function of windowBits and memLevel.
+
+     The strategy parameter is used to tune the compression algorithm. Use the
+   value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
+   filter (or predictor), or Z_HUFFMAN_ONLY to force Huffman encoding only (no
+   string match).  Filtered data consists mostly of small values with a
+   somewhat random distribution. In this case, the compression algorithm is
+   tuned to compress them better. The effect of Z_FILTERED is to force more
+   Huffman coding and less string matching; it is somewhat intermediate
+   between Z_DEFAULT and Z_HUFFMAN_ONLY. The strategy parameter only affects
+   the compression ratio but not the correctness of the compressed output even
+   if it is not set appropriately.

+
+     The dictionary should consist of strings (byte sequences) that are likely
+   to be encountered later in the data to be compressed, with the most commonly
+   used strings preferably put towards the end of the dictionary. Using a

+   *
+   *  small technical note
+   *  --------------------
+   *
+   *  We use a few tricks in this implementation that are explained here to
+   *  ease debugging and maintenance.
+   *
+   *  - First of all, the `prefix' and `suffix' arrays contain the suffix
+   *    and prefix for codes over 256; this means that
+   *
+   *      prefix_of(code) == state->prefix[code-256]
+   *      suffix_of(code) == state->suffix[code-256]
+   *
+   *    Each prefix is a 16-bit code, and each suffix an 8-bit byte.
+   *
+   *    Both arrays are stored in a single memory block, pointed to by
+   *    `state->prefix'.  This means that the following equality is always
+   *    true:
+   *
+   *      state->suffix == (FT_Byte*)(state->prefix + state->prefix_size)
+   *
+   *    Of course, state->prefix_size is the number of prefix/suffix slots
+   *    in the arrays, corresponding to codes 256..255+prefix_size.
+   *
+   *  - `free_ent' is the index of the next free entry in the `prefix'
+   *    and `suffix' arrays.  This means that the corresponding `next free
+   *    code' is really `256+free_ent'.
+   *
+   *    Moreover, `max_free' is the maximum value that `free_ent' can reach.
+   *
+   *    `max_free' corresponds to `(1 << max_bits) - 256'.  Note that this
+   *    value is always <= 0xFF00, which means that both `free_ent' and
+   *    `max_free' can be stored in an FT_UInt variable, even on 16-bit
+   *    machines.
+   *
+   *    If `free_ent == max_free', you cannot add new codes to the
+   *    prefix/suffix table.
+   *
+   *  - `num_bits' is the current number of code bits, starting at 9 and
+   *    growing each time `free_ent' reaches the value of `free_bits'.  The
+   *    latter is computed as follows
+   *
+   *      if num_bits < max_bits:
+   *         free_bits = (1 << num_bits)-256
+   *      else:
+   *         free_bits = max_free + 1
+   *
+   *    Since the value of `max_free + 1' can never be reached by
+   *    `free_ent', `num_bits' cannot grow larger than `max_bits'.

+Introduction
+************
+
+PCF (Portable Compiled Format) is a binary bitmap font format, largely used
+in X world. This code implements a PCF driver for the FreeType library.
+Glyph images are loaded into memory only on demand, thus leading to a small
+memory footprint.
+
+Information on the PCF font format can only be worked out from
+`pcfread.c', and `pcfwrite.c', to be found, for instance, in the XFree86
+(www.xfree86.org) source tree (xc/lib/font/bitmap/).
+
+Many good bitmap fonts in bdf format come with XFree86: they can be
+compiled into the pcf format using the `bdftopcf' utility.
+
+
+Supported hardware
+******************
+
+The driver has been tested on linux/x86 and sunos5.5/sparc.  In both
+cases the compiler was gcc.  When back in Paris, I will test it also
+on linux/alpha.
+
+
+Encodings
+*********
+
+Use `FT_Get_BDF_Charset_ID' to access the encoding and registry.
+
+The driver always exports `ft_encoding_none' as face->charmap.encoding.
+FT_Get_Char_Index() behavior is unmodified, that is, it converts the ULong
+value given as argument into the corresponding glyph number.
+
+
+Known problems
+**************
+
+- dealing explicitly with encodings breaks the uniformity of FreeType 2
+  API.
+
+- except for encodings properties, client applications have no
+  visibility of the PCF_Face object.  This means that applications
+  cannot directly access font tables and are obliged to trust
+  FreeType.
+
+- currently, glyph names and ink_metrics are ignored.
+
+I plan to give full visibility of the PCF_Face object in the next
+release of the driver, thus implementing also glyph names and
+ink_metrics.
+
+- height is defined as (ascent - descent).  Is this correct?
+
+- if unable to read size information from the font, PCF_Init_Face
+  sets available_size->width and available_size->height to 12.
+
+- too many english grammar errors in the readme file :-(

+Keith Packard wrote the pcf driver found in XFree86.  His work is at
+the same time the specification and the sample implementation of the
+PCF format.  Undoubtedly, this driver is inspired from his work.

+   * A `CF2_Blues' object stores the blue zones (horizontal alignment
+   * zones) of a font.  These are specified in the CFF private dictionary
+   * by `BlueValues', `OtherBlues', `FamilyBlues', and `FamilyOtherBlues'.
+   * Each zone is defined by a top and bottom edge in character space.
+   * Further, each zone is either a top zone or a bottom zone, as recorded
+   * by `bottomZone'.
+   *
+   * The maximum number of `BlueValues' and `FamilyBlues' is 7 each.
+   * However, these are combined to produce a total of 7 zones.
+   * Similarly, the maximum number of `OtherBlues' and `FamilyOtherBlues'
+   * is 5 and these are combined to produce an additional 5 zones.
+   *
+   * Blue zones are used to `capture' hints and force them to a common
+   * alignment point.  This alignment is recorded in device space in
+   * `dsFlatEdge'.  Except for this value, a `CF2_Blues' object could be
+   * constructed independently of scaling.  Construction may occur once
+   * the matrix is known.  Other features implemented in the Capture
+   * method are overshoot suppression, overshoot enforcement, and Blue
+   * Boost.
+   *
+   * Capture is determined by `BlueValues' and `OtherBlues', but the
+   * alignment point may be adjusted to the scaled flat edge of
+   * `FamilyBlues' or `FamilyOtherBlues'.  No alignment is done to the

+   * A poor-man error facility.
+   *
+   * This code being written in vanilla C, doesn't have the luxury of a
+   * language-supported exception mechanism such as the one available in
+   * Java.  Instead, we are stuck with using error codes that must be
+   * carefully managed and preserved.  However, it is convenient for us to
+   * model our error mechanism on a Java-like exception mechanism.
+   * When we assign an error code we are thus `throwing' an error.
+   *
+   * The preservation of an error code is done by coding convention.
+   * Upon a function call if the error code is anything other than
+   * `FT_Err_Ok', which is guaranteed to be zero, we
+   * will return without altering that error.  This will allow the
+   * error to propagate and be handled at the appropriate location in
+   * the code.
+   *
+   * This allows a style of code where the error code is initialized
+   * up front and a block of calls are made with the error code only
+   * being checked after the block.  If a new error occurs, the original
+   * error will be preserved and a functional no-op should result in any
+   * subsequent function that has an initial error code not equal to
+   * `FT_Err_Ok'.
+   *
+   * Errors are encoded by calling the `FT_THROW' macro.  For example,
+   *
+   * {
+   *   FT_Error  e;
+   *
+   *
+   *   ...

+##  SOURCE BLOCK FORMAT CLASS
+##
+##  A simple class containing compiled regular expressions to detect
+##  potential documentation format block comments within C source code.
+##
+##  The `column' pattern must contain a group to `unbox' the content of
+##  documentation comment blocks.
+##
+##  Later on, paragraphs are converted to long lines, which simplifies the
+##  regular expressions that act upon the text.

+ftfuzzer
+========
+
+
+ftfuzzer.cc
+-----------
+
+This file contains a target function  for FreeType fuzzing.  It can be
+used   with    libFuzzer   (https://llvm.org/docs/LibFuzzer.html)   or
+potentially any other similar fuzzer.
+
+Usage:
+
+  1. Build  `libfreetype.a' and  `ftfuzzer.cc' using  the most  recent
+     clang compiler with these flags:
+
+       # for fuzzer coverage feedback
+       -fsanitize-coverage=edge,8bit-counters
+       # for bug checking
+       -fsanitize=address,signed-integer-overflow,shift
+
+     You  also need  the header  files from  the `libarchive'  library
+     (https://www.libarchive.org/)  for handling  tar files  (see file
+     `ftmutator.cc' below for more).
+
+  2. Link with `libFuzzer' (it contains `main') and `libarchive'.
+
+  3. Run the fuzzer on some test corpus.
+
+The exact flags and commands may vary.
+
+  https://github.com/google/oss-fuzz/tree/master/projects/freetype2
+
+There is a continuous fuzzing bot that runs ftfuzzer.
+
+  https://oss-fuzz.com
+
+(You need an account  to be able to see coverage  reports and the like
+on oss-fuzz.com.)
+
+Check the bot configuration for the most current settings.
+
+
+ftmutator.cc
+------------
+
+FreeType has the  ability to `attach' auxiliary files to  a font file,
+providing additional information.  The main usage is to load AFM files
+for PostScript Type 1 fonts.
+
+However, libFuzzer currently only supports  mutation of a single input
+file.   For  this  reason,  `ftmutator.cc' contains  a  custom  fuzzer
+mutator that uses an uncompressed tar  file archive as the input.  The
+first file in  such a tarball gets  opened by FreeType as  a font, all
+other files are treated as input for `FT_Attach_Stream'.
+
+Compilation is similar to `ftfuzzer.c'.
+
+
+runinput.cc
+-----------
+
+To run the target function on a set of input files, this file contains
+a   convenience  `main'   function.   Link   it  with   `ftfuzzer.cc',
+`libfreetype.a', and `libarchive' and run like
+
+  ./a.out my_tests_inputs/*

+ftrandom
+========
+
+This program expects a set of directories containing good fonts, and a set
+of extensions of fonts to be tested.  It will randomly pick a font, copy it,
+introduce an error and then test it.
+
+The FreeType tests are quite basic; for each erroneous font ftrandom
+
+  . forks off a new tester,
+  . initializes the library,
+  . opens each font in the file,
+  . loads each glyph,
+  . optionally reviews the contours of the glyph,
+  . optionally rasterizes the glyph, and
+  . closes the face.
+
+If a tester takes longer than 20 seconds, ftrandom saves the erroneous font
+and continues.  If the tester exits normally or with an error, then the
+superstructure removes the test font and continues.
+
+
+Command line options
+--------------------
+
+  --all                    Test every font in the directory(ies) no matter
+                           what its extension.
+  --check-outlines         Call `FT_Outline_Decompose' on each glyph.
+  --dir <dir>              Append <dir> to the list of directories to search
+                           for good fonts.  No recursive search.
+  --error-count <cnt>      Introduce <cnt> single-byte errors into the
+                           erroneous fonts (default: 1).
+  --error-fraction <frac>  Multiply the file size of the font by <frac> and
+                           introduce that many errors into the erroneous
+                           font file.  <frac> should be in the range [0;1]
+                           (default: 0.0).
+  --ext <ext>              Add <ext> to the set of font types tested.
+  --help                   Print out this list of options.
+  --nohints                Specify FT_LOAD_NO_HINTING when loading glyphs.
+  --rasterize              Call `FT_Render_Glyph' as well as loading it.
+  --result <dir>           This is the directory in which test files are
+                           placed.
+  --test <file>            Run a single test on a pre-generated testcase.
+                           This is done in the current process so it can be
+                           debugged more easily.
+
+The default font extensions tested by ftrandom are
+
+  .ttf .otf .ttc .cid .pfb .pfa .bdf .pcf .pfr .fon .otb .cff
+
+The default font directory is controlled by the macro `GOOD_FONTS_DIR' in
+the source code (and can be thus specified during compilation); its default
+value is
+
+  /usr/local/share/fonts
+
+The default result directory is `results' (in the current directory).
+
+
+Compilation
+-----------
+
+Two possible solutions.
+
+. Run ftrandom within a debugging tool like `valgrind' to catch various
+  memory issues.
+
+. Compile FreeType with sanitizer flags as provided by gcc or clang, for
+  example, then link it with ftrandom.

+# We now store the Adobe Glyph List in compressed form.  The list is put
+# into a data structure called `trie' (because it has a tree-like
+# appearance).  Consider, for example, that you want to store the
+# following name mapping:
+#
+#   A        => 1
+#   Aacute   => 6
+#   Abalon   => 2
+#   Abstract => 4
+#
+# It is possible to store the entries as follows.
+#
+#   A => 1
+#   |
+#   +-acute => 6
+#   |
+#   +-b
+#     |
+#     +-alon => 2
+#     |
+#     +-stract => 4
+#
+# We see that each node in the trie has:
+#
+# - one or more `letters'
+# - an optional value
+# - zero or more child nodes
+#
+# The first step is to call
+#
+#   root = StringNode( "", 0 )
+#   for word in map.values():
+#     root.add( word, map[word] )
+#
+# which creates a large trie where each node has only one children.
+#
+# Executing
+#
+#   root = root.optimize()
+#
+# optimizes the trie by merging the letters of successive nodes whenever
+# possible.
+#
+# Each node of the trie is stored as follows.
+#
+# - First the node's letter, according to the following scheme.  We
+#   use the fact that in the AGL no name contains character codes > 127.
+#
+#     name         bitsize     description
+#     ----------------------------------------------------------------
+#     notlast            1     Set to 1 if this is not the last letter
+#                              in the word.
+#     ascii              7     The letter's ASCII value.
+#
+# - The letter is followed by a children count and the value of the
+#   current key (if any).  Again we can do some optimization because all
+#   AGL entries are from the BMP; this means that 16 bits are sufficient
+#   to store its Unicode values.  Additionally, no node has more than
+#   127 children.
+#
+#     name         bitsize     description
+#     -----------------------------------------
+#     hasvalue           1     Set to 1 if a 16-bit Unicode value follows.
+#     num_children       7     Number of children.  Can be 0 only if
+#                              `hasvalue' is set to 1.
+#     value             16     Optional Unicode value.
+#
+# - A node is finished by a list of 16bit absolute offsets to the
+#   children, which must be sorted in increasing order of their first
+#   letter.
+#
+# For simplicity, all 16bit quantities are stored in big-endian order.
+#
+# The root node has first letter = 0, and no value.

+   * Calculate the phantom points
+   *
+   * Defining the right side bearing (rsb) as

+   *
+   * (with `aw' the advance width, `lsb' the left side bearing, and `xmin'
+   * and `xmax' the glyph's minimum and maximum x value), the OpenType
+   * specification defines the initial position of horizontal phantom points
+   * as
+   *
+   *   pp1 = (round(xmin - lsb), 0)      ,
+   *   pp2 = (round(pp1 + aw), 0)        .
+   *
+   * Note that the rounding to the grid (in the device space) is not
+   * documented currently in the specification.
+   *
+   * However, the specification lacks the precise definition of vertical
+   * phantom points.  Greg Hitchcock provided the following explanation.
+   *
+   * - a `vmtx' table is present
+   *
+   *   For any glyph, the minimum and maximum y values (`ymin' and `ymax')
+   *   are given in the `glyf' table, the top side bearing (tsb) and advance
+   *   height (ah) are given in the `vmtx' table.  The bottom side bearing
+   *   (bsb) is then calculated as
+   *
+   *     bsb = ah - (tsb + ymax - ymin)       ,
+   *
+   *   and the initial position of vertical phantom points is
+   *
+   *     pp3 = (x, round(ymax + tsb))       ,
+   *     pp4 = (x, round(pp3 - ah))         .
+   *
+   *   See below for value `x'.
+   *
+   * - no `vmtx' table in the font
+   *
+   *   If there is an `OS/2' table, we set
+   *
+   *     DefaultAscender = sTypoAscender       ,
+   *     DefaultDescender = sTypoDescender     ,
+   *
+   *   otherwise we use data from the `hhea' table:
+   *
+   *     DefaultAscender = Ascender         ,
+   *     DefaultDescender = Descender       .
+   *
+   *   With these two variables we can now set
+   *
+   *     ah = DefaultAscender - sDefaultDescender    ,
+   *     tsb = DefaultAscender - yMax                ,
+   *
+   *   and proceed as if a `vmtx' table was present.
+   *
+   * Usually we have
+   *
+   *   x = aw / 2      ,                                                (1)
+   *
+   * but there is one compatibility case where it can be set to
+   *
+   *   x = -DefaultDescender -
+   *         ((DefaultAscender - DefaultDescender - aw) / 2)     .      (2)
+   *
+   * and another one with
+   *
+   *   x = 0     .                                                      (3)

+     * FreeType supports ClearType-like hinting of TrueType fonts through
+     * the version 40 interpreter.  This is achieved through several hacks
+     * in the base (v35) interpreter, as detailed below.
+     *
+     * ClearType is an umbrella term for several rendering techniques
+     * employed by Microsoft's various GUI and rendering toolkit
+     * implementations, most importantly: subpixel rendering for using the
+     * RGB subpixels of LCDs to approximately triple the perceived
+     * resolution on the x-axis and subpixel hinting for positioning stems
+     * on subpixel borders.  TrueType programming is explicit, i.e., fonts
+     * must be programmed to take advantage of ClearType's possibilities.
+     *
+     * When ClearType was introduced, it seemed unlikely that all fonts
+     * would be reprogrammed, so Microsoft decided to implement a backward
+     * compatibility mode.  It employs several simple to complicated
+     * assumptions and tricks, many of them font-dependent, that modify the
+     * interpretation of the bytecode contained in these fonts to retrofit
+     * them into a ClearType-y look.  The quality of the results varies.
+     * Most (web)fonts that were released since then have come to rely on
+     * these hacks to render correctly, even some of Microsoft's flagship
+     * fonts (e.g., Calibri, Cambria, Segoe UI).
+     *
+     * FreeType's minimal subpixel hinting code (interpreter version 40)
+     * employs a small list of font-agnostic hacks loosely based on the
+     * public information available on Microsoft's compatibility mode[2].
+     * The focus is on modern (web)fonts rather than legacy fonts that were
+     * made for monochrome rendering.  It will not match ClearType rendering
+     * exactly.  Unlike the `Infinality' code (interpreter version 38) that
+     * came before, it will not try to toggle hacks for specific fonts for
+     * performance and complexity reasons.  It will fall back to version 35
+     * behavior for tricky fonts[1] or when monochrome rendering is
+     * requested.
+     *
+     * Major hacks
+     *
+     * - Any point movement on the x axis is ignored (cf. `Direct_Move' and
+     *   `Direct_Move_X').  This has the smallest code footprint and single
+     *   biggest effect.  The ClearType way to increase resolution is
+     *   supersampling the x axis, the FreeType way is ignoring instructions
+     *   on the x axis, which gives the same result in the majority of
+     *   cases.
+     *
+     * - Points are not moved post-IUP (neither on the x nor on the y axis),
+     *   except the x component of diagonal moves post-IUP (cf.
+     *   `Direct_Move', `Direct_Move_Y', `Move_Zp2_Point').  Post-IUP
+     *   changes are commonly used to `fix' pixel patterns which has little
+     *   use outside monochrome rendering.
+     *
+     * - SHPIX and DELTAP don't execute unless moving a composite on the
+     *   y axis or moving a previously y touched point.  SHPIX additionally
+     *   denies movement on the x axis (cf. `Ins_SHPIX' and `Ins_DELTAP').
+     *   Both instructions are commonly used to `fix' pixel patterns for
+     *   monochrome or Windows's GDI rendering but make little sense for
+     *   FreeType rendering.  Both can distort the outline.  See [2] for
+     *   details.
+     *
+     * - The hdmx table and modifications to phantom points are ignored.
+     *   Bearings and advance widths remain unchanged (except rounding them
+     *   outside the interpreter!), cf. `compute_glyph_metrics' and
+     *   `TT_Hint_Glyph'.  Letting non-native-ClearType fonts modify spacing
+     *   might mess up spacing.
+     *
+     * Minor hacks
+     *
+     * - FLIPRGON, FLIPRGOFF, and FLIPPT don't execute post-IUP.  This
+     *   prevents dents in e.g. Arial-Regular's `D' and `G' glyphs at
+     *   various sizes.
+     *
+     * (Post-IUP is the state after both IUP[x] and IUP[y] have been
+     * executed.)
+     *
+     * The best results are achieved for fonts that were from the outset
+     * designed with ClearType in mind, meaning they leave the x axis mostly
+     * alone and don't mess with the `final' outline to produce more
+     * pleasing pixel patterns.  The harder the designer tried to produce
+     * very specific patterns (`superhinting') for pre-ClearType-displays,
+     * the worse the results.
+     *
+     * Microsoft defines a way to turn off backward compatibility and
+     * interpret instructions as before (called `native ClearType')[2][3].
+     * The font designer then regains full control and is responsible for
