+ * RLE encoding for software colorkey and alpha-channel acceleration
+ *
+ * Original version by Sam Lantinga
+ *
+ * Mattias Engdegård (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.
+ *   i.e. if the target has the format         rrrrrggggggbbbbb,
+ *   the encoded pixel will be 00000gggggg00000rrrrr0aaaaabbbbb.
+ *   The <skip> and <run> counts are 8 bit for the opaque lines, 16 bit
+ *   for the translucent lines. Two padding bytes may be inserted
+ *   before each translucent line to keep them 32-bit aligned.
+ *
+ *   The end of the sequence is marked by a zero <skip>,<run> pair at the
+ *   beginning of an opaque line.

+ * This file should be included as

+ * 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

+ *    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
+using QtWayland's "qmlcompositor" as Wayland server. This is needed for touch
+input when running SDL applications under a qmlcompositor Wayland server.
+
+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/
+
+Generate headers and glue code:
+    for extension in touch-extension surface-extension windowmanager; do
+        wayland-scanner client-header < src/extensions/$extension.xml > wayland-qt-$extension.h
+        wayland-scanner code < src/extensions/$extension.xml > wayland-qt-$extension.c

+     * 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.

+       extensions via SDL_GL_DeduceMaxSupportedESProfile. This uses
+       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
+        // to a Win32 HWND) 'PointerCursor' property.
+        //
+        // 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:

+    //  - 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

+// 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.
