-Android
-================================================================================
-
-Matt Styles wrote a tutorial on building SDL for Android with Visual Studio:
-http://trederia.blogspot.de/2017/03/building-sdl2-for-android-with-visual.html
-
-The rest of this README covers the old style build process.
-
-================================================================================
- Requirements
-================================================================================
-
-Android SDK (version 16 or later)
-https://developer.android.com/sdk/index.html
-
-Android NDK r7 or later
-https://developer.android.com/tools/sdk/ndk/index.html
-
-Minimum API level supported by SDL: 10 (Android 2.3.3)
-Joystick support is available for API level >= 12 devices.
-
-================================================================================
- How the port works
-================================================================================
-
-- Android applications are Java-based, optionally with parts written in C
-- As SDL apps are C-based, we use a small Java shim that uses JNI to talk to 
-  the SDL library
-- This means that your application C code must be placed inside an Android 
-  Java project, along with some C support code that communicates with Java
-- This eventually produces a standard Android .apk package
-
-The Android Java code implements an "Activity" and can be found in:
-android-project/src/org/libsdl/app/SDLActivity.java
-
-The Java code loads your game code, the SDL shared library, and
-dispatches to native functions implemented in the SDL library:
-src/core/android/SDL_android.c
-
-Your project must include some glue code that starts your main() routine:
-src/main/android/SDL_android_main.c
-
-
-================================================================================
- Building an app
-================================================================================
-
-For simple projects you can use the script located at build-scripts/androidbuild.sh
-
-There's two ways of using it:
-
-    androidbuild.sh com.yourcompany.yourapp < sources.list
-    androidbuild.sh com.yourcompany.yourapp source1.c source2.c ...sourceN.c
-
-sources.list should be a text file with a source file name in each line
-Filenames should be specified relative to the current directory, for example if
-you are in the build-scripts directory and want to create the testgles.c test, you'll
-run:
-
-    ./androidbuild.sh org.libsdl.testgles ../test/testgles.c
-
-One limitation of this script is that all sources provided will be aggregated into
-a single directory, thus all your source files should have a unique name.
-
-Once the project is complete the script will tell you where the debug APK is located.
-If you want to create a signed release APK, you can use the project created by this
-utility to generate it.
-
-Finally, a word of caution: re running androidbuild.sh wipes any changes you may have
-done in the build directory for the app!
-
-
-For more complex projects, follow these instructions:
-    
-1. Copy the android-project directory wherever you want to keep your projects
-   and rename it to the name of your project.
-2. Move or symlink this SDL directory into the "<project>/jni" directory
-3. Edit "<project>/jni/src/Android.mk" to include your source files
-4. Run 'ndk-build' (a script provided by the NDK). This compiles the C source
-
-If you want to use the Eclipse IDE, skip to the Eclipse section below.
-
-5. Create "<project>/local.properties" and use that to point to the Android SDK directory, by writing a line with the following form:
-
-       sdk.dir=PATH_TO_ANDROID_SDK
-
-6. Run 'ant debug' in android/project. This compiles the .java and eventually 
-   creates a .apk with the native code embedded
-7. 'ant debug install' will push the apk to the device or emulator (if connected)
-
-Here's an explanation of the files in the Android project, so you can customize them:
-
-    android-project/
-        AndroidManifest.xml	- package manifest. Among others, it contains the class name
-        			  of the main Activity and the package name of the application.
-        build.properties	- empty
-        build.xml		- build description file, used by ant. The actual application name
-        			  is specified here.
-        default.properties	- holds the target ABI for the application, android-10 and up
-        project.properties	- holds the target ABI for the application, android-10 and up
-        local.properties	- holds the SDK path, you should change this to the path to your SDK
-        jni/			- directory holding native code
-        jni/Android.mk		- Android makefile that can call recursively the Android.mk files
-        			  in all subdirectories
-        jni/SDL/		- (symlink to) directory holding the SDL library files
-        jni/SDL/Android.mk	- Android makefile for creating the SDL shared library
-        jni/src/		- directory holding your C/C++ source
-        jni/src/Android.mk	- Android makefile that you should customize to include your 
-                                  source code and any library references
-        res/			- directory holding resources for your application
-        res/drawable-*		- directories holding icons for different phone hardware. Could be
-        			  one dir called "drawable".
-        res/layout/main.xml	- Usually contains a file main.xml, which declares the screen layout.
-        			  We don't need it because we use the SDL video output.
-        res/values/strings.xml	- strings used in your application, including the application name
-        			  shown on the phone.
-        src/org/libsdl/app/SDLActivity.java - the Java class handling the initialization and binding
-        			  to SDL.  Be very careful changing this, as the SDL library relies
-        			  on this implementation.
-
-
-================================================================================
- Build an app with static linking of libSDL
-================================================================================
-
-This build uses the Android NDK module system.
-
-Instructions:
-1. Copy the android-project directory wherever you want to keep your projects
-   and rename it to the name of your project.
-2. Rename "<project>/jni/src/Android_static.mk" to "<project>/jni/src/Android.mk"
-   (overwrite the existing one)
-3. Edit "<project>/jni/src/Android.mk" to include your source files
-4. create and export an environment variable named NDK_MODULE_PATH that points
-   to the parent directory of this SDL directory. e.g.:
-
-       export NDK_MODULE_PATH="$PWD"/..
-
-5. Edit "<project>/src/org/libsdl/app/SDLActivity.java" and remove the call to
-   System.loadLibrary("SDL2").
-6. Run 'ndk-build' (a script provided by the NDK). This compiles the C source
-
-
-================================================================================
- Customizing your application name
-================================================================================
-
-To customize your application name, edit AndroidManifest.xml and replace
-"org.libsdl.app" with an identifier for your product package.
-
-Then create a Java class extending SDLActivity and place it in a directory
-under src matching your package, e.g.
-
-    src/com/gamemaker/game/MyGame.java
-
-Here's an example of a minimal class file:
-
-    --- MyGame.java --------------------------
-    package com.gamemaker.game;
-    
-    import org.libsdl.app.SDLActivity; 
-    
-    /**
-     * A sample wrapper class that just calls SDLActivity 
-     */ 
-    
-    public class MyGame extends SDLActivity { }
-    
-    ------------------------------------------
-
-Then replace "SDLActivity" in AndroidManifest.xml with the name of your
-class, .e.g. "MyGame"
-
-================================================================================
- Customizing your application icon
-================================================================================
-
-Conceptually changing your icon is just replacing the "ic_launcher.png" files in
-the drawable directories under the res directory. There are four directories for
-different screen sizes. These can be replaced with one dir called "drawable",
-containing an icon file "ic_launcher.png" with dimensions 48x48 or 72x72.
-
-You may need to change the name of your icon in AndroidManifest.xml to match
-this icon filename.
-
-================================================================================
- Loading assets
-================================================================================
-
-Any files you put in the "assets" directory of your android-project directory
-will get bundled into the application package and you can load them using the
-standard functions in SDL_rwops.h.
-
-There are also a few Android specific functions that allow you to get other
-useful paths for saving and loading data:
-* SDL_AndroidGetInternalStoragePath()
-* SDL_AndroidGetExternalStorageState()
-* SDL_AndroidGetExternalStoragePath()
-
-See SDL_system.h for more details on these functions.
-
-The asset packaging system will, by default, compress certain file extensions.
-SDL includes two asset file access mechanisms, the preferred one is the so
-called "File Descriptor" method, which is faster and doesn't involve the Dalvik
-GC, but given this method does not work on compressed assets, there is also the
-"Input Stream" method, which is automatically used as a fall back by SDL. You
-may want to keep this fact in mind when building your APK, specially when large
-files are involved.
-For more information on which extensions get compressed by default and how to
-disable this behaviour, see for example:
-    
-http://ponystyle.com/blog/2010/03/26/dealing-with-asset-compression-in-android-apps/
-
-================================================================================
- Pause / Resume behaviour
-================================================================================
-
-If SDL is compiled with SDL_ANDROID_BLOCK_ON_PAUSE defined (the default),
-the event loop will block itself when the app is paused (ie, when the user
-returns to the main Android dashboard). Blocking is better in terms of battery
-use, and it allows your app to spring back to life instantaneously after resume
-(versus polling for a resume message).
-
-Upon resume, SDL will attempt to restore the GL context automatically.
-In modern devices (Android 3.0 and up) this will most likely succeed and your
-app can continue to operate as it was.
-
-However, there's a chance (on older hardware, or on systems under heavy load),
-where the GL context can not be restored. In that case you have to listen for
-a specific message, (which is not yet implemented!) and restore your textures
-manually or quit the app (which is actually the kind of behaviour you'll see
-under iOS, if the OS can not restore your GL context it will just kill your app)
-
-================================================================================
- Threads and the Java VM
-================================================================================
-
-For a quick tour on how Linux native threads interoperate with the Java VM, take
-a look here: https://developer.android.com/guide/practices/jni.html
-
-If you want to use threads in your SDL app, it's strongly recommended that you
-do so by creating them using SDL functions. This way, the required attach/detach
-handling is managed by SDL automagically. If you have threads created by other
-means and they make calls to SDL functions, make sure that you call
-Android_JNI_SetupThread() before doing anything else otherwise SDL will attach
-your thread automatically anyway (when you make an SDL call), but it'll never
-detach it.
-
-================================================================================
- Using STL
-================================================================================
-
-You can use STL in your project by creating an Application.mk file in the jni
-folder and adding the following line:
-
-    APP_STL := stlport_static
-
-For more information check out CPLUSPLUS-SUPPORT.html in the NDK documentation.
-
-================================================================================
- Additional documentation
-================================================================================
-
-The documentation in the NDK docs directory is very helpful in understanding the
-build process and how to work with native code on the Android platform.
-
-The best place to start is with docs/OVERVIEW.TXT
-
-
-================================================================================
- Using Eclipse
-================================================================================
-
-First make sure that you've installed Eclipse and the Android extensions as described here:
-	https://developer.android.com/tools/sdk/eclipse-adt.html
-
-Once you've copied the SDL android project and customized it, you can create an Eclipse project from it:
- * File -> New -> Other
- * Select the Android -> Android Project wizard and click Next
- * Enter the name you'd like your project to have
- * Select "Create project from existing source" and browse for your project directory
- * Make sure the Build Target is set to Android 3.1 (API 12)
- * Click Finish
-
-
-================================================================================
- Using the emulator
-================================================================================
-
-There are some good tips and tricks for getting the most out of the
-emulator here: https://developer.android.com/tools/devices/emulator.html
-
-Especially useful is the info on setting up OpenGL ES 2.0 emulation.
-
-Notice that this software emulator is incredibly slow and needs a lot of disk space.
-Using a real device works better.
-
-================================================================================
- Troubleshooting
-================================================================================
-
-You can create and run an emulator from the Eclipse IDE:
- * Window -> Android SDK and AVD Manager
-
-You can see if adb can see any devices with the following command:
-
-    adb devices
-
-You can see the output of log messages on the default device with:
-
-    adb logcat
-
-You can push files to the device with:
-
-    adb push local_file remote_path_and_file
-
-You can push files to the SD Card at /sdcard, for example:
-
-    adb push moose.dat /sdcard/moose.dat
-
-You can see the files on the SD card with a shell command:
-
-    adb shell ls /sdcard/
-
-You can start a command shell on the default device with:
-
-    adb shell
-
-You can remove the library files of your project (and not the SDL lib files) with:
-
-    ndk-build clean
-
-You can do a build with the following command:
-
-    ndk-build
-
-You can see the complete command line that ndk-build is using by passing V=1 on the command line:
-
-    ndk-build V=1
-
-If your application crashes in native code, you can use addr2line to convert the
-addresses in the stack trace to lines in your code.
-
-For example, if your crash looks like this:
-
-    I/DEBUG   (   31): signal 11 (SIGSEGV), code 2 (SEGV_ACCERR), fault addr 400085d0
-    I/DEBUG   (   31):  r0 00000000  r1 00001000  r2 00000003  r3 400085d4
-    I/DEBUG   (   31):  r4 400085d0  r5 40008000  r6 afd41504  r7 436c6a7c
-    I/DEBUG   (   31):  r8 436c6b30  r9 435c6fb0  10 435c6f9c  fp 4168d82c
-    I/DEBUG   (   31):  ip 8346aff0  sp 436c6a60  lr afd1c8ff  pc afd1c902  cpsr 60000030
-    I/DEBUG   (   31):          #00  pc 0001c902  /system/lib/libc.so
-    I/DEBUG   (   31):          #01  pc 0001ccf6  /system/lib/libc.so
-    I/DEBUG   (   31):          #02  pc 000014bc  /data/data/org.libsdl.app/lib/libmain.so
-    I/DEBUG   (   31):          #03  pc 00001506  /data/data/org.libsdl.app/lib/libmain.so
-
-You can see that there's a crash in the C library being called from the main code.
-I run addr2line with the debug version of my code:
-
-    arm-eabi-addr2line -C -f -e obj/local/armeabi/libmain.so
-
-and then paste in the number after "pc" in the call stack, from the line that I care about:
-000014bc
-
-I get output from addr2line showing that it's in the quit function, in testspriteminimal.c, on line 23.
-
-You can add logging to your code to help show what's happening:
-
-    #include <android/log.h>
-    
-    __android_log_print(ANDROID_LOG_INFO, "foo", "Something happened! x = %d", x);
-
-If you need to build without optimization turned on, you can create a file called
-"Application.mk" in the jni directory, with the following line in it:
-
-    APP_OPTIM := debug
-
-
-================================================================================
- Memory debugging
-================================================================================
-
-The best (and slowest) way to debug memory issues on Android is valgrind.
-Valgrind has support for Android out of the box, just grab code using:
-
-    svn co svn://svn.valgrind.org/valgrind/trunk valgrind
-
-... and follow the instructions in the file README.android to build it.
-
-One thing I needed to do on Mac OS X was change the path to the toolchain,
-and add ranlib to the environment variables:
-export RANLIB=$NDKROOT/toolchains/arm-linux-androideabi-4.4.3/prebuilt/darwin-x86/bin/arm-linux-androideabi-ranlib
-
-Once valgrind is built, you can create a wrapper script to launch your
-application with it, changing org.libsdl.app to your package identifier:
-
-    --- start_valgrind_app -------------------
-    #!/system/bin/sh
-    export TMPDIR=/data/data/org.libsdl.app
-    exec /data/local/Inst/bin/valgrind --log-file=/sdcard/valgrind.log --error-limit=no $*
-    ------------------------------------------
-
-Then push it to the device:
-
-    adb push start_valgrind_app /data/local
-
-and make it executable:
-
-    adb shell chmod 755 /data/local/start_valgrind_app
-
-and tell Android to use the script to launch your application:
-
-    adb shell setprop wrap.org.libsdl.app "logwrapper /data/local/start_valgrind_app"
-
-If the setprop command says "could not set property", it's likely that
-your package name is too long and you should make it shorter by changing
-AndroidManifest.xml and the path to your class file in android-project/src
-
-You can then launch your application normally and waaaaaaaiiittt for it.
-You can monitor the startup process with the logcat command above, and
-when it's done (or even while it's running) you can grab the valgrind
-output file:
-
-    adb pull /sdcard/valgrind.log
-
-When you're done instrumenting with valgrind, you can disable the wrapper:
-
-    adb shell setprop wrap.org.libsdl.app ""
-
-================================================================================
- Graphics debugging
-================================================================================
-
-If you are developing on a compatible Tegra-based tablet, NVidia provides
-Tegra Graphics Debugger at their website.  Because SDL2 dynamically loads EGL
-and GLES libraries, you must follow their instructions for installing the
-interposer library on a rooted device.  The non-rooted instructions are not
-compatible with applications that use SDL2 for video.
-
-The Tegra Graphics Debugger is available from NVidia here:
-https://developer.nvidia.com/tegra-graphics-debugger
-
-================================================================================
- Why is API level 10 the minimum required?
-================================================================================
-
-API level 10 is the minimum required level at runtime (that is, on the device) 
-because SDL requires some functionality for running not
-available on older devices. Since the incorporation of joystick support into SDL,
-the minimum SDK required to *build* SDL is version 12. Devices running API levels
-10-11 are still supported, only with the joystick functionality disabled.
-
-Support for native OpenGL ES and ES2 applications was introduced in the NDK for
-API level 4 and 8. EGL was made a stable API in the NDK for API level 9, which
-has since then been obsoleted, with the recommendation to developers to bump the
-required API level to 10.
-As of this writing, according to https://developer.android.com/about/dashboards/index.html
-about 90% of the Android devices accessing Google Play support API level 10 or
-higher (March 2013).
-
-================================================================================
- A note regarding the use of the "dirty rectangles" rendering technique
-================================================================================
-
-If your app uses a variation of the "dirty rectangles" rendering technique,
-where you only update a portion of the screen on each frame, you may notice a
-variety of visual glitches on Android, that are not present on other platforms.
-This is caused by SDL's use of EGL as the support system to handle OpenGL ES/ES2
-contexts, in particular the use of the eglSwapBuffers function. As stated in the
-documentation for the function "The contents of ancillary buffers are always 
-undefined after calling eglSwapBuffers".
-Setting the EGL_SWAP_BEHAVIOR attribute of the surface to EGL_BUFFER_PRESERVED
-is not possible for SDL as it requires EGL 1.4, available only on the API level
-17+, so the only workaround available on this platform is to redraw the entire
-screen each frame.
-
-Reference: http://www.khronos.org/registry/egl/specs/EGLTechNote0001.html
-
-================================================================================
- Known issues
-================================================================================
-
-- The number of buttons reported for each joystick is hardcoded to be 36, which
-is the current maximum number of buttons Android can report.

-SDL's build system was traditionally based on autotools. Over time, this
-approach has suffered from several issues across the different supported 
-platforms.
-To solve these problems, a new build system based on CMake is under development.
-It works in parallel to the legacy system, so users can experiment with it

-While still experimental, the build system should be usable on the following
-platforms:
-
-* FreeBSD
-* Linux
-* VS.NET 2010
-* MinGW and Msys
-* OS X with support for XCode
-
-
-================================================================================
-Usage
-================================================================================
-
-Assuming the source for SDL is located at ~/sdl
-
-    cd ~
-    mkdir build
-    cd build
-    cmake ../sdl
-
-This will build the static and dynamic versions of SDL in the ~/build directory.

-DirectFB
-========
-
-Supports:
-
-- Hardware YUV overlays
-- OpenGL - software only
-- 2D/3D accelerations (depends on directfb driver)
-- multiple displays
-- windows
-
-What you need:
-
-* DirectFB 1.0.1, 1.2.x, 1.3.0
-* Kernel-Framebuffer support: required: vesafb, radeonfb .... 
-* Mesa 7.0.x	   - optional for OpenGL
-
-/etc/directfbrc
-
-This file should contain the following lines to make
-your joystick work and avoid crashes:
-------------------------
-disable-module=joystick
-disable-module=cle266
-disable-module=cyber5k
-no-linux-input-grab
-------------------------
-
-To disable to use x11 backend when DISPLAY variable is found use
-
-export SDL_DIRECTFB_X11_CHECK=0
-
-To disable the use of linux input devices, i.e. multimice/multikeyboard support,
-use
-
-export SDL_DIRECTFB_LINUX_INPUT=0
-
-To use hardware accelerated YUV-overlays for YUV-textures, use:
-
-export SDL_DIRECTFB_YUV_DIRECT=1
-
-This is disabled by default. It will only support one 
-YUV texture, namely the first. Every other YUV texture will be
-rendered in software.
-
-In addition, you may use (directfb-1.2.x)
-
-export SDL_DIRECTFB_YUV_UNDERLAY=1
-
-to make the YUV texture an underlay. This will make the cursor to
-be shown.
-
-Simple Window Manager
-=====================
-
-The driver has support for a very, very basic window manager you may
-want to use when running with "wm=default". Use
-
-export SDL_DIRECTFB_WM=1
-
-to enable basic window borders. In order to have the window title rendered,
-you need to have the following font installed:
-
-/usr/share/fonts/truetype/freefont/FreeSans.ttf
-
-OpenGL Support
-==============
-
-The following instructions will give you *software* OpenGL. However this
-works at least on all directfb supported platforms.
-
-As of this writing 20100802 you need to pull Mesa from git and do the following:
-
-------------------------
-git clone git://anongit.freedesktop.org/git/mesa/mesa
-cd mesa 
-git checkout 2c9fdaf7292423c157fc79b5ce43f0f199dd753a

-Dynamic API
-================================================================================
-Originally posted by Ryan at:
-  https://plus.google.com/103391075724026391227/posts/TB8UfnDYu4U
-
-Background:
-
-- The Steam Runtime has (at least in theory) a really kick-ass build of SDL2, 
-  but developers are shipping their own SDL2 with individual Steam games. 
-  These games might stop getting updates, but a newer SDL2 might be needed later. 
-  Certainly we'll always be fixing bugs in SDL, even if a new video target isn't 
-  ever needed, and these fixes won't make it to a game shipping its own SDL.
-- Even if we replace the SDL2 in those games with a compatible one, that is to 
-  say, edit a developer's Steam depot (yuck!), there are developers that are 
-  statically linking SDL2 that we can't do this for. We can't even force the 
-  dynamic loader to ignore their SDL2 in this case, of course.
-- If you don't ship an SDL2 with the game in some form, people that disabled the
-  Steam Runtime, or just tried to run the game from the command line instead of 
-  Steam might find themselves unable to run the game, due to a missing dependency.
-- If you want to ship on non-Steam platforms like GOG or Humble Bundle, or target
-  generic Linux boxes that may or may not have SDL2 installed, you have to ship 
-  the library or risk a total failure to launch. So now, you might have to have 
-  a non-Steam build plus a Steam build (that is, one with and one without SDL2 
-  included), which is inconvenient if you could have had one universal build 
-  that works everywhere.
-- We like the zlib license, but the biggest complaint from the open source 
-  community about the license change is the static linking. The LGPL forced this 
-  as a legal, not technical issue, but zlib doesn't care. Even those that aren't
-  concerned about the GNU freedoms found themselves solving the same problems: 
-  swapping in a newer SDL to an older game often times can save the day. 
-  Static linking stops this dead.
-
-So here's what we did:
-
-SDL now has, internally, a table of function pointers. So, this is what SDL_Init
-now looks like:
-
-    UInt32 SDL_Init(Uint32 flags)
-    {
-        return jump_table.SDL_Init(flags);
-    }
-
-Except that is all done with a bunch of macro magic so we don't have to maintain
-every one of these.
-
-What is jump_table.SDL_init()? Eventually, that's a function pointer of the real
-SDL_Init() that you've been calling all this time. But at startup, it looks more 
-like this:
-
-    Uint32 SDL_Init_DEFAULT(Uint32 flags)
-    {
-        SDL_InitDynamicAPI();
-        return jump_table.SDL_Init(flags);
-    }
-
-SDL_InitDynamicAPI() fills in jump_table with all the actual SDL function 
-pointers, which means that this _DEFAULT function never gets called again. 
-First call to any SDL function sets the whole thing up.
-
-So you might be asking, what was the value in that? Isn't this what the operating
-system's dynamic loader was supposed to do for us? Yes, but now we've got this 
-level of indirection, we can do things like this:
-
-    export SDL_DYNAMIC_API=/my/actual/libSDL-2.0.so.0
-    ./MyGameThatIsStaticallyLinkedToSDL2
-
-And now, this game that is staticallly linked to SDL, can still be overridden 
-with a newer, or better, SDL. The statically linked one will only be used as 
-far as calling into the jump table in this case. But in cases where no override
-is desired, the statically linked version will provide its own jump table, 
-and everyone is happy.
-
-So now:
-- Developers can statically link SDL, and users can still replace it. 
-  (We'd still rather you ship a shared library, though!)
-- Developers can ship an SDL with their game, Valve can override it for, say, 
-  new features on SteamOS, or distros can override it for their own needs, 
-  but it'll also just work in the default case.
-- Developers can ship the same package to everyone (Humble Bundle, GOG, etc), 
-  and it'll do the right thing.
-- End users (and Valve) can update a game's SDL in almost any case, 
-  to keep abandoned games running on newer platforms.
-- Everyone develops with SDL exactly as they have been doing all along. 
-  Same headers, same ABI. Just get the latest version to enable this magic.
-
-
-A little more about SDL_InitDynamicAPI():
-
-Internally, InitAPI does some locking to make sure everything waits until a 
-single thread initializes everything (although even SDL_CreateThread() goes 
-through here before spinning a thread, too), and then decides if it should use
-an external SDL library. If not, it sets up the jump table using the current 
-SDL's function pointers (which might be statically linked into a program, or in
-a shared library of its own). If so, it loads that library and looks for and 
-calls a single function:
-
-    SInt32 SDL_DYNAPI_entry(Uint32 version, void *table, Uint32 tablesize);
-
-That function takes a version number (more on that in a moment), the address of
-the jump table, and the size, in bytes, of the table. 
-Now, we've got policy here: this table's layout never changes; new stuff gets 
-added to the end. Therefore SDL_DYNAPI_entry() knows that it can provide all 
-the needed functions if tablesize <= sizeof its own jump table. If tablesize is
-bigger (say, SDL 2.0.4 is trying to load SDL 2.0.3), then we know to abort, but
-if it's smaller, we know we can provide the entire API that the caller needs.
-
-The version variable is a failsafe switch. 
-Right now it's always 1. This number changes when there are major API changes 
-(so we know if the tablesize might be smaller, or entries in it have changed). 
-Right now SDL_DYNAPI_entry gives up if the version doesn't match, but it's not 
-inconceivable to have a small dispatch library that only supplies this one 
-function and loads different, otherwise-incompatible SDL libraries and has the
-right one initialize the jump table based on the version. For something that 
-must generically catch lots of different versions of SDL over time, like the 
-Steam Client, this isn't a bad option.
-
-Finally, I'm sure some people are reading this and thinking,
-"I don't want that overhead in my project!"  
-To which I would point out that the extra function call through the jump table 
-probably wouldn't even show up in a profile, but lucky you: this can all be 
-disabled. You can build SDL without this if you absolutely must, but we would 
-encourage you not to do that. However, on heavily locked down platforms like 
-iOS, or maybe when debugging, it makes sense to disable it. The way this is
-designed in SDL, you just have to change one #define, and the entire system 
-vaporizes out, and SDL functions exactly like it always did. Most of it is 
-macro magic, so the system is contained to one C file and a few headers. 
-However, this is on by default and you have to edit a header file to turn it 
-off. Our hopes is that if we make it easy to disable, but not too easy, 
-everyone will ultimately be able to get what they want, but we've gently 
-nudged everyone towards what we think is the best solution.

-Dollar Gestures
-===========================================================================
-SDL provides an implementation of the $1 gesture recognition system. This allows for recording, saving, loading, and performing single stroke gestures.
-
-Gestures can be performed with any number of fingers (the centroid of the fingers must follow the path of the gesture), but the number of fingers must be constant (a finger cannot go down in the middle of a gesture). The path of a gesture is considered the path from the time when the final finger went down, to the first time any finger comes up. 
-
-Dollar gestures are assigned an Id based on a hash function. This is guaranteed to remain constant for a given gesture. There is a (small) chance that two different gestures will be assigned the same ID. In this case, simply re-recording one of the gestures should result in a different ID.
-
-Recording:
-----------
-To begin recording on a touch device call:
-SDL_RecordGesture(SDL_TouchID touchId), where touchId is the id of the touch device you wish to record on, or -1 to record on all connected devices.
-
-Recording terminates as soon as a finger comes up. Recording is acknowledged by an SDL_DOLLARRECORD event.
-A SDL_DOLLARRECORD event is a dgesture with the following fields:
-
-* event.dgesture.touchId   - the Id of the touch used to record the gesture.
-* event.dgesture.gestureId - the unique id of the recorded gesture.
-
-
-Performing:
------------
-As long as there is a dollar gesture assigned to a touch, every finger-up event will also cause an SDL_DOLLARGESTURE event with the following fields:
-
-* event.dgesture.touchId    - the Id of the touch which performed the gesture.
-* event.dgesture.gestureId  - the unique id of the closest gesture to the performed stroke.
-* event.dgesture.error      - the difference between the gesture template and the actual performed gesture. Lower error is a better match.
-* event.dgesture.numFingers - the number of fingers used to draw the stroke.
-
-Most programs will want to define an appropriate error threshold and check to be sure that the error of a gesture is not abnormally high (an indicator that no gesture was performed).
-
-
-
-Saving:
--------
-To save a template, call SDL_SaveDollarTemplate(gestureId, dst) where gestureId is the id of the gesture you want to save, and dst is an SDL_RWops pointer to the file where the gesture will be stored.
-
-To save all currently loaded templates, call SDL_SaveAllDollarTemplates(dst) where dst is an SDL_RWops pointer to the file where the gesture will be stored.
-
-Both functions return the number of gestures successfully saved.
-
-
-Loading:
---------
-To load templates from a file, call SDL_LoadDollarTemplates(touchId,src) where touchId is the id of the touch to load to (or -1 to load to all touch devices), and src is an SDL_RWops pointer to a gesture save file. 
-
-SDL_LoadDollarTemplates returns the number of templates successfully loaded.
-
-
-
-===========================================================================
-Multi Gestures
-===========================================================================
-SDL provides simple support for pinch/rotate/swipe gestures. 
-Every time a finger is moved an SDL_MULTIGESTURE event is sent with the following fields:
-
-* event.mgesture.touchId - the Id of the touch on which the gesture was performed.
-* event.mgesture.x       - the normalized x coordinate of the gesture. (0..1)
-* event.mgesture.y       - the normalized y coordinate of the gesture. (0..1)
-* event.mgesture.dTheta  - the amount that the fingers rotated during this motion.
-* event.mgesture.dDist   - the amount that the fingers pinched during this motion.
-* event.mgesture.numFingers - the number of fingers used in the gesture.
-

-Mercurial
-=========
-
-The latest development version of SDL is available via Mercurial.
-Mercurial allows you to get up-to-the-minute fixes and enhancements;
-as a developer works on a source tree, you can use "hg" to mirror that
-source tree instead of waiting for an official release. Please look
-at the Mercurial website ( https://www.mercurial-scm.org/ ) for more
-information on using hg, where you can also download software for
-Mac OS X, Windows, and Unix systems.
-
-    hg clone http://hg.libsdl.org/SDL
-
-If you are building SDL via configure, you will need to run autogen.sh
-before running configure.
-
-There is a web interface to the subversion repository at:
-	http://hg.libsdl.org/SDL/
-
-There is an RSS feed available at that URL, for those that want to
-track commits in real time.

-iOS
-======
-
-==============================================================================
-Building the Simple DirectMedia Layer for iOS 5.1+
-==============================================================================
-
-Requirements: Mac OS X 10.8 or later and the iOS 7+ SDK.
-
-Instructions:
-
-1.  Open SDL.xcodeproj (located in Xcode-iOS/SDL) in Xcode.
-2.  Select your desired target, and hit build.
-
-There are three build targets:
-- libSDL.a:
-	Build SDL as a statically linked library
-- testsdl:
-	Build a test program (there are known test failures which are fine)
-- Template:
-	Package a project template together with the SDL for iPhone static libraries and copies of the SDL headers.  The template includes proper references to the SDL library and headers, skeleton code for a basic SDL program, and placeholder graphics for the application icon and startup screen.
-
-
-==============================================================================
-Build SDL for iOS from the command line
-==============================================================================
-
-1. cd (PATH WHERE THE SDL CODE IS)/build-scripts
-2. ./iosbuild.sh
-
-If everything goes fine, you should see a build/ios directory, inside there's
-two directories "lib" and "include". 
-"include" contains a copy of the SDL headers that you'll need for your project,
-make sure to configure XCode to look for headers there.
-"lib" contains find two files, libSDL2.a and libSDL2main.a, you have to add both 
-to your XCode project. These libraries contain three architectures in them,
-armv6 for legacy devices, armv7, and i386 (for the simulator).
-By default, iosbuild.sh will autodetect the SDK version you have installed using 
-xcodebuild -showsdks, and build for iOS >= 3.0, you can override this behaviour 
-by setting the MIN_OS_VERSION variable, ie:
-
-MIN_OS_VERSION=4.2 ./iosbuild.sh
-
-==============================================================================
-Using the Simple DirectMedia Layer for iOS
-==============================================================================
-
-FIXME: This needs to be updated for the latest methods
-
-Here is the easiest method:
-1.  Build the SDL library (libSDL2.a) and the iPhone SDL Application template.
-2.  Install the iPhone SDL Application template by copying it to one of Xcode's template directories.  I recommend creating a directory called "SDL" in "/Developer/Platforms/iOS.platform/Developer/Library/Xcode/Project Templates/" and placing it there.
-3.  Start a new project using the template.  The project should be immediately ready for use with SDL.
-
-Here is a more manual method:
-1.  Create a new iOS view based application.
-2.  Build the SDL static library (libSDL2.a) for iOS and include them in your project.  Xcode will ignore the library that is not currently of the correct architecture, hence your app will work both on iOS and in the iOS Simulator.
-3.  Include the SDL header files in your project.
-4.  Remove the ApplicationDelegate.h and ApplicationDelegate.m files -- SDL for iOS provides its own UIApplicationDelegate.  Remove MainWindow.xib -- SDL for iOS produces its user interface programmatically.
-5.  Delete the contents of main.m and program your app as a regular SDL program instead.  You may replace main.m with your own main.c, but you must tell Xcode not to use the project prefix file, as it includes Objective-C code.
-
-==============================================================================
-Notes -- Retina / High-DPI and window sizes
-==============================================================================
-
-Window and display mode sizes in SDL are in "screen coordinates" (or "points",
-in Apple's terminology) rather than in pixels. On iOS this means that a window
-created on an iPhone 6 will have a size in screen coordinates of 375 x 667,
-rather than a size in pixels of 750 x 1334. All iOS apps are expected to
-size their content based on screen coordinates / points rather than pixels,
-as this allows different iOS devices to have different pixel densities
-(Retina versus non-Retina screens, etc.) without apps caring too much.
-
-By default SDL will not use the full pixel density of the screen on
-Retina/high-dpi capable devices. Use the SDL_WINDOW_ALLOW_HIGHDPI flag when
-creating your window to enable high-dpi support.
-
-When high-dpi support is enabled, SDL_GetWindowSize() and display mode sizes
-will still be in "screen coordinates" rather than pixels, but the window will
-have a much greater pixel density when the device supports it, and the
-SDL_GL_GetDrawableSize() or SDL_GetRendererOutputSize() functions (depending on
-whether raw OpenGL or the SDL_Render API is used) can be queried to determine
-the size in pixels of the drawable screen framebuffer.
-
-Some OpenGL ES functions such as glViewport expect sizes in pixels rather than
-sizes in screen coordinates. When doing 2D rendering with OpenGL ES, an
-orthographic projection matrix using the size in screen coordinates
-(SDL_GetWindowSize()) can be used in order to display content at the same scale
-no matter whether a Retina device is used or not.
-
-==============================================================================
-Notes -- Application events
-==============================================================================
-
-On iOS the application goes through a fixed life cycle and you will get
-notifications of state changes via application events. When these events
-are delivered you must handle them in an event callback because the OS may
-not give you any processing time after the events are delivered.
-
-e.g.
-
-    int HandleAppEvents(void *userdata, SDL_Event *event)
-    {
-        switch (event->type)
-        {
-        case SDL_APP_TERMINATING:
-            /* Terminate the app.
-               Shut everything down before returning from this function.
-            */
-            return 0;
-        case SDL_APP_LOWMEMORY:
-            /* You will get this when your app is paused and iOS wants more memory.
-               Release as much memory as possible.
-            */
-            return 0;
-        case SDL_APP_WILLENTERBACKGROUND:
-            /* Prepare your app to go into the background.  Stop loops, etc.
-               This gets called when the user hits the home button, or gets a call.
-            */
-            return 0;
-        case SDL_APP_DIDENTERBACKGROUND:
-            /* This will get called if the user accepted whatever sent your app to the background.
-               If the user got a phone call and canceled it, you'll instead get an SDL_APP_DIDENTERFOREGROUND event and restart your loops.
-               When you get this, you have 5 seconds to save all your state or the app will be terminated.
-               Your app is NOT active at this point.
-            */
-            return 0;
-        case SDL_APP_WILLENTERFOREGROUND:
-            /* This call happens when your app is coming back to the foreground.
-               Restore all your state here.
-            */
-            return 0;
-        case SDL_APP_DIDENTERFOREGROUND:
-            /* Restart your loops here.
-               Your app is interactive and getting CPU again.
-            */
-            return 0;
-        default:
-            /* No special processing, add it to the event queue */
-            return 1;
-        }
-    }
-    
-    int main(int argc, char *argv[])
-    {
-        SDL_SetEventFilter(HandleAppEvents, NULL);
-    
-        ... run your main loop
-    
-        return 0;
-    }
-

-==============================================================================
-Notes -- Accelerometer as Joystick
-==============================================================================
-
-SDL for iPhone supports polling the built in accelerometer as a joystick device.  For an example on how to do this, see the accelerometer.c in the demos directory.
-
-The main thing to note when using the accelerometer with SDL is that while the iPhone natively reports accelerometer as floating point values in units of g-force, SDL_JoystickGetAxis() reports joystick values as signed integers.  Hence, in order to convert between the two, some clamping and scaling is necessary on the part of the iPhone SDL joystick driver.  To convert SDL_JoystickGetAxis() reported values BACK to units of g-force, simply multiply the values by SDL_IPHONE_MAX_GFORCE / 0x7FFF.
-
-==============================================================================
-Notes -- OpenGL ES
-==============================================================================
-
-Your SDL application for iOS uses OpenGL ES for video by default.
-
-OpenGL ES for iOS supports several display pixel formats, such as RGBA8 and RGB565, which provide a 32 bit and 16 bit color buffer respectively. By default, the implementation uses RGB565, but you may use RGBA8 by setting each color component to 8 bits in SDL_GL_SetAttribute().
-
-If your application doesn't use OpenGL's depth buffer, you may find significant performance improvement by setting SDL_GL_DEPTH_SIZE to 0.
-
-Finally, if your application completely redraws the screen each frame, you may find significant performance improvement by setting the attribute SDL_GL_RETAINED_BACKING to 0.
-
-OpenGL ES on iOS doesn't use the traditional system-framebuffer setup provided in other operating systems. Special care must be taken because of this:
-
-- The drawable Renderbuffer must be bound to the GL_RENDERBUFFER binding point when SDL_GL_SwapWindow() is called.
-- The drawable Framebuffer Object must be bound while rendering to the screen and when SDL_GL_SwapWindow() is called.
-- If multisample antialiasing (MSAA) is used and glReadPixels is used on the screen, the drawable framebuffer must be resolved to the MSAA resolve framebuffer (via glBlitFramebuffer or glResolveMultisampleFramebufferAPPLE), and the MSAA resolve framebuffer must be bound to the GL_READ_FRAMEBUFFER binding point, before glReadPixels is called.
-
-The above objects can be obtained via SDL_GetWindowWMInfo() (in SDL_syswm.h).
-
-==============================================================================
-Notes -- Keyboard
-==============================================================================
-
-The SDL keyboard API has been extended to support on-screen keyboards:
-
-void SDL_StartTextInput()
-	-- enables text events and reveals the onscreen keyboard.
-
-void SDL_StopTextInput()
-	-- disables text events and hides the onscreen keyboard.
-
-SDL_bool SDL_IsTextInputActive()
-	-- returns whether or not text events are enabled (and the onscreen keyboard is visible)
-
-
-==============================================================================
-Notes -- Reading and Writing files
-==============================================================================
-
-Each application installed on iPhone resides in a sandbox which includes its own Application Home directory.  Your application may not access files outside this directory.
-
-Once your application is installed its directory tree looks like:
-
-    MySDLApp Home/
-        MySDLApp.app
-        Documents/
-        Library/
-            Preferences/
-        tmp/
-
-When your SDL based iPhone application starts up, it sets the working directory to the main bundle (MySDLApp Home/MySDLApp.app), where your application resources are stored.  You cannot write to this directory.  Instead, I advise you to write document files to "../Documents/" and preferences to "../Library/Preferences".  
-
-More information on this subject is available here:
-http://developer.apple.com/library/ios/#documentation/iPhone/Conceptual/iPhoneOSProgrammingGuide/Introduction/Introduction.html
-
-==============================================================================
-Notes -- iPhone SDL limitations
-==============================================================================
-
-Windows:
-	Full-size, single window applications only.  You cannot create multi-window SDL applications for iPhone OS.  The application window will fill the display, though you have the option of turning on or off the menu-bar (pass SDL_CreateWindow() the flag SDL_WINDOW_BORDERLESS).
-
-Textures:
-	The optimal texture formats on iOS are SDL_PIXELFORMAT_ABGR8888, SDL_PIXELFORMAT_ABGR8888, SDL_PIXELFORMAT_BGR888, and SDL_PIXELFORMAT_RGB24 pixel formats.
-
-Loading Shared Objects:
-	This is disabled by default since it seems to break the terms of the iOS SDK agreement for iOS versions prior to iOS 8. It can be re-enabled in SDL_config_iphoneos.h.
-
-==============================================================================
-Game Center 
-==============================================================================
-
-Game Center integration might require that you break up your main loop in order to yield control back to the system. In other words, instead of running an endless main loop, you run each frame in a callback function, using:
-
-    int SDL_iPhoneSetAnimationCallback(SDL_Window * window, int interval, void (*callback)(void*), void *callbackParam);
-
-This will set up the given function to be called back on the animation callback, and then you have to return from main() to let the Cocoa event loop run.
-
-e.g.
-
-    extern "C"
-    void ShowFrame(void*)
-    {
-        ... do event handling, frame logic and rendering ...
-    }
-    
-    int main(int argc, char *argv[])
-    {
-        ... initialize game ...
-    
-    #if __IPHONEOS__
-        // Initialize the Game Center for scoring and matchmaking
-        InitGameCenter();
-    
-        // Set up the game to run in the window animation callback on iOS
-        // so that Game Center and so forth works correctly.
-        SDL_iPhoneSetAnimationCallback(window, 1, ShowFrame, NULL);
-    #else
-        while ( running ) {
-            ShowFrame(0);
-            DelayFrame();
-        }
-    #endif
-        return 0;
-    }
-
-==============================================================================
-Deploying to older versions of iOS
-==============================================================================
-
-SDL supports deploying to older versions of iOS than are supported by the latest version of Xcode, all the way back to iOS 6.1
-
-In order to do that you need to download an older version of Xcode:
-https://developer.apple.com/download/more/?name=Xcode
-
-Open the package contents of the older Xcode and your newer version of Xcode and copy over the folders in Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
-
-Then open the file Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/SDKSettings.plist and add the versions of iOS you want to deploy to the key Root/DefaultProperties/DEPLOYMENT_TARGET_SUGGESTED_VALUES
-
-Open your project and set your deployment target to the desired version of iOS
-
-Finally, remove GameController from the list of frameworks linked by your application and edit the build settings for "Other Linker Flags" and add -weak_framework GameController

-================================================================================

-- libsamplerate0-dev lets SDL optionally link to libresamplerate at runtime
-  for higher-quality audio resampling. SDL will work without it if the library

-You'll hopefully see your joystick listed along with a name like "/dev/input/eventXX"
-Now run:
-    
-    cat /dev/input/event/XX
-
-If you get a permission error, you need to set a udev rule to change the mode of
-your device (see below)    
-    
-Also, try:
-    
-    sudo udevadm info --query=all --name=input/eventXX
-    
-If you see a line stating ID_INPUT_JOYSTICK=1, great, if you don't see it,
-you need to set up an udev rule to force this variable.
-
-A combined rule for the Saitek Pro Flight Rudder Pedals to fix both issues looks 
-like:
-    
-   SUBSYSTEM=="input", ATTRS{idProduct}=="0763", ATTRS{idVendor}=="06a3", MODE="0666", ENV{ID_INPUT_JOYSTICK}="1"
-   SUBSYSTEM=="input", ATTRS{idProduct}=="0764", ATTRS{idVendor}=="06a3", MODE="0666", ENV{ID_INPUT_JOYSTICK}="1"
-   
-You can set up similar rules for your device by changing the values listed in
-idProduct and idVendor. To obtain these values, try:
-    
-    sudo udevadm info -a --name=input/eventXX | grep idVendor
-    sudo udevadm info -a --name=input/eventXX | grep idProduct
-    
-If multiple values come up for each of these, the one you want is the first one of each.    
-
-On other systems which ship with an older udev (such as CentOS), you may need
-to set up a rule such as:
-    
-    SUBSYSTEM=="input", ENV{ID_CLASS}=="joystick", ENV{ID_INPUT_JOYSTICK}="1"

-Mac OS X
-==============================================================================
-
-These instructions are for people using Apple's Mac OS X (pronounced
-"ten").
-
-From the developer's point of view, OS X is a sort of hybrid Mac and
-Unix system, and you have the option of using either traditional
-command line tools or Apple's IDE Xcode.
-
-Command Line Build
-==================
-
-To build SDL using the command line, use the standard configure and make
-process:
-
-    ./configure
-    make
-    sudo make install
-
-You can also build SDL as a Universal library (a single binary for both
-32-bit and 64-bit Intel architectures), on Mac OS X 10.7 and newer, by using
-the gcc-fat.sh script in build-scripts:
-
-    mkdir mybuild
-    cd mybuild
-    CC=$PWD/../build-scripts/gcc-fat.sh CXX=$PWD/../build-scripts/g++-fat.sh ../configure
-    make
-    sudo make install
-
-This script builds SDL with 10.5 ABI compatibility on i386 and 10.6
-ABI compatibility on x86_64 architectures.  For best compatibility you
-should compile your application the same way.
-
-Please note that building SDL requires at least Xcode 4.6 and the 10.7 SDK
-(even if you target back to 10.5 systems). PowerPC support for Mac OS X has
-been officially dropped as of SDL 2.0.2.
-
-To use the library once it's built, you essential have two possibilities:
-use the traditional autoconf/automake/make method, or use Xcode.
-
-==============================================================================
-Caveats for using SDL with Mac OS X
-==============================================================================
-
-Some things you have to be aware of when using SDL on Mac OS X:
-
-- If you register your own NSApplicationDelegate (using [NSApp setDelegate:]),
-  SDL will not register its own. This means that SDL will not terminate using
-  SDL_Quit if it receives a termination request, it will terminate like a 
-  normal app, and it will not send a SDL_DROPFILE when you request to open a
-  file with the app. To solve these issues, put the following code in your 
-  NSApplicationDelegate implementation:
-
-
-    - (NSApplicationTerminateReply)applicationShouldTerminate:(NSApplication *)sender
-    {
-        if (SDL_GetEventState(SDL_QUIT) == SDL_ENABLE) {
-            SDL_Event event;
-            event.type = SDL_QUIT;
-            SDL_PushEvent(&event);
-        }
-    
-        return NSTerminateCancel;
-    }
-    
-    - (BOOL)application:(NSApplication *)theApplication openFile:(NSString *)filename
-    {
-        if (SDL_GetEventState(SDL_DROPFILE) == SDL_ENABLE) {
-            SDL_Event event;
-            event.type = SDL_DROPFILE;
-            event.drop.file = SDL_strdup([filename UTF8String]);
-            return (SDL_PushEvent(&event) > 0);
-        }
-    
-        return NO;
-    }
-
-==============================================================================
-Using the Simple DirectMedia Layer with a traditional Makefile
-==============================================================================
-
-An existing autoconf/automake build system for your SDL app has good chances
-to work almost unchanged on OS X. However, to produce a "real" Mac OS X binary
-that you can distribute to users, you need to put the generated binary into a
-so called "bundle", which basically is a fancy folder with a name like
-"MyCoolGame.app".
-
-To get this build automatically, add something like the following rule to
-your Makefile.am:
-
-    bundle_contents = APP_NAME.app/Contents
-    APP_NAME_bundle: EXE_NAME
-    	mkdir -p $(bundle_contents)/MacOS
-    	mkdir -p $(bundle_contents)/Resources
-    	echo "APPL????" > $(bundle_contents)/PkgInfo
-    	$(INSTALL_PROGRAM) $< $(bundle_contents)/MacOS/
-
-You should replace EXE_NAME with the name of the executable. APP_NAME is what
-will be visible to the user in the Finder. Usually it will be the same
-as EXE_NAME but capitalized. E.g. if EXE_NAME is "testgame" then APP_NAME 
-usually is "TestGame". You might also want to use `@PACKAGE@` to use the package
-name as specified in your configure.in file.
-
-If your project builds more than one application, you will have to do a bit
-more. For each of your target applications, you need a separate rule.
-
-If you want the created bundles to be installed, you may want to add this
-rule to your Makefile.am:
-
-    install-exec-hook: APP_NAME_bundle
-    	rm -rf $(DESTDIR)$(prefix)/Applications/APP_NAME.app
-    	mkdir -p $(DESTDIR)$(prefix)/Applications/
-    	cp -r $< /$(DESTDIR)$(prefix)Applications/
-
-This rule takes the Bundle created by the rule from step 3 and installs them
-into "$(DESTDIR)$(prefix)/Applications/".
-
-Again, if you want to install multiple applications, you will have to augment
-the make rule accordingly.
-
-
-But beware! That is only part of the story! With the above, you end up with
-a bare bone .app bundle, which is double clickable from the Finder. But
-there are some more things you should do before shipping your product...
-
-1) The bundle right now probably is dynamically linked against SDL. That 
-   means that when you copy it to another computer, *it will not run*,
-   unless you also install SDL on that other computer. A good solution
-   for this dilemma is to static link against SDL. On OS X, you can
-   achieve that by linking against the libraries listed by
-
-       sdl-config --static-libs
-
-   instead of those listed by
-
-       sdl-config --libs
-
-   Depending on how exactly SDL is integrated into your build systems, the
-   way to achieve that varies, so I won't describe it here in detail
-
-2) Add an 'Info.plist' to your application. That is a special XML file which
-   contains some meta-information about your application (like some copyright
-   information, the version of your app, the name of an optional icon file,
-   and other things). Part of that information is displayed by the Finder
-   when you click on the .app, or if you look at the "Get Info" window.
-   More information about Info.plist files can be found on Apple's homepage.
-
-
-As a final remark, let me add that I use some of the techniques (and some
-variations of them) in Exult and ScummVM; both are available in source on
-the net, so feel free to take a peek at them for inspiration!
-
-
-==============================================================================
-Using the Simple DirectMedia Layer with Xcode
-==============================================================================
-
-These instructions are for using Apple's Xcode IDE to build SDL applications.
-
-- First steps
-
-The first thing to do is to unpack the Xcode.tar.gz archive in the
-top level SDL directory (where the Xcode.tar.gz archive resides).
-Because Stuffit Expander will unpack the archive into a subdirectory,
-you should unpack the archive manually from the command line:
-
-    cd [path_to_SDL_source]
-    tar zxf Xcode.tar.gz
-
-This will create a new folder called Xcode, which you can browse
-normally from the Finder.
-
-- Building the Framework
-
-The SDL Library is packaged as a framework bundle, an organized
-relocatable folder hierarchy of executable code, interface headers,
-and additional resources. For practical purposes, you can think of a 
-framework as a more user and system-friendly shared library, whose library
-file behaves more or less like a standard UNIX shared library.
-
-To build the framework, simply open the framework project and build it. 
-By default, the framework bundle "SDL.framework" is installed in 
-/Library/Frameworks. Therefore, the testers and project stationary expect
-it to be located there. However, it will function the same in any of the
-following locations:
-
-    ~/Library/Frameworks
-    /Local/Library/Frameworks
-    /System/Library/Frameworks
-
-- Build Options
-    There are two "Build Styles" (See the "Targets" tab) for SDL.
-    "Deployment" should be used if you aren't tweaking the SDL library.
-    "Development" should be used to debug SDL apps or the library itself.
-
-- Building the Testers
-    Open the SDLTest project and build away!
-
-- Using the Project Stationary
-    Copy the stationary to the indicated folders to access it from
-    the "New Project" and "Add target" menus. What could be easier?
-
-- Setting up a new project by hand
-    Some of you won't want to use the Stationary so I'll give some tips:
-    * Create a new "Cocoa Application"
-    * Add src/main/macosx/SDLMain.m , .h and .nib to your project
-    * Remove "main.c" from your project
-    * Remove "MainMenu.nib" from your project
-    * Add "$(HOME)/Library/Frameworks/SDL.framework/Headers" to include path
-    * Add "$(HOME)/Library/Frameworks" to the frameworks search path
-    * Add "-framework SDL -framework Foundation -framework AppKit" to "OTHER_LDFLAGS"
-    * Set the "Main Nib File" under "Application Settings" to "SDLMain.nib"
-    * Add your files
-    * Clean and build
-
-- Building from command line
-    Use pbxbuild in the same directory as your .pbproj file
-
-- Running your app
-    You can send command line args to your app by either invoking it from
-    the command line (in *.app/Contents/MacOS) or by entering them in the
-    "Executables" panel of the target settings.
-    
-- Implementation Notes
-    Some things that may be of interest about how it all works...
-    * Working directory
-        As defined in the SDL_main.m file, the working directory of your SDL app
-        is by default set to its parent. You may wish to change this to better
-        suit your needs.
-    * You have a Cocoa App!
-        Your SDL app is essentially a Cocoa application. When your app
-        starts up and the libraries finish loading, a Cocoa procedure is called,
-        which sets up the working directory and calls your main() method.
-        You are free to modify your Cocoa app with generally no consequence 
-        to SDL. You cannot, however, easily change the SDL window itself.
-        Functionality may be added in the future to help this.
-

-Native Client
-================================================================================
-
-Requirements: 
-
-* Native Client SDK (https://developer.chrome.com/native-client), 
-  (tested with Pepper version 33 or higher).
-
-The SDL backend for Chrome's Native Client has been tested only with the PNaCl
-toolchain, which generates binaries designed to run on ARM and x86_32/64 
-platforms. This does not mean it won't work with the other toolchains!
-
-================================================================================
-Building SDL for NaCl
-================================================================================
-
-Set up the right environment variables (see naclbuild.sh), then configure SDL with:
-
-    configure --host=pnacl --prefix some/install/destination
-    
-Then "make". 
-
-As an example of how to create a deployable app a Makefile project is provided 
-in test/nacl/Makefile, which includes some monkey patching of the common.mk file 
-provided by NaCl, without which linking properly to SDL won't work (the search 
-path can't be modified externally, so the linker won't find SDL's binaries unless 
-you dump them into the SDK path, which is inconvenient).
-Also provided in test/nacl is the required support file, such as index.html, 
-manifest.json, etc.
-SDL apps for NaCl run on a worker thread using the ppapi_simple infrastructure.
-This allows for blocking calls on all the relevant systems (OpenGL ES, filesystem),
-hiding the asynchronous nature of the browser behind the scenes...which is not the
-same as making it disappear!
-
-
-================================================================================
-Running tests
-================================================================================
-
-Due to the nature of NaCl programs, building and running SDL tests is not as
-straightforward as one would hope. The script naclbuild.sh in build-scripts 
-automates the process and should serve as a guide for users of SDL trying to build 
-their own applications.
-
-Basic usage:
-    
-    ./naclbuild.sh path/to/pepper/toolchain (i.e. ~/naclsdk/pepper_35)
-    
-This will build testgles2.c by default.
-
-If you want to build a different test, for example testrendercopyex.c:
-    
-    SOURCES=~/sdl/SDL/test/testrendercopyex.c ./naclbuild.sh ~/naclsdk/pepper_35
-    
-Once the build finishes, you have to serve the contents with a web server (the
-script will give you instructions on how to do that with Python).
-
-================================================================================
-RWops and nacl_io
-================================================================================
-
-SDL_RWops work transparently with nacl_io. Two functions control the mount points:
-    
-    int mount(const char* source, const char* target, 
-                      const char* filesystemtype, 
-                      unsigned long mountflags, const void *data);
-    int umount(const char *target);
-    
-    For convenience, SDL will by default mount an httpfs tree at / before calling 
-the app's main function. Such setting can be overridden by calling:
-    
-    umount("/");
-
-And then mounting a different filesystem at /
-
-It's important to consider that the asynchronous nature of file operations on a
-browser is hidden from the application, effectively providing the developer with
-a set of blocking file operations just like you get in a regular desktop 
-environment, which eases the job of porting to Native Client, but also introduces 
-a set of challenges of its own, in particular when big file sizes and slow 
-connections are involved.
-
-For more information on how nacl_io and mount points work, see:
-    
-    https://developer.chrome.com/native-client/devguide/coding/nacl_io
-    https://src.chromium.org/chrome/trunk/src/native_client_sdk/src/libraries/nacl_io/nacl_io.h
-
-To be able to save into the directory "/save/" (like backup of game) :
-
-    mount("", "/save", "html5fs", 0, "type=PERSISTENT");
-
-And add to manifest.json :
-
-    "permissions": [
-        "unlimitedStorage"
-    ]
-
-================================================================================
-TODO - Known Issues
-================================================================================
-* Testing of all systems with a real application (something other than SDL's tests)
-* Key events don't seem to work properly

-Porting
-=======
-
-* Porting To A New Platform
-
-  The first thing you have to do when porting to a new platform, is look at
-include/SDL_platform.h and create an entry there for your operating system.
-The standard format is "__PLATFORM__", where PLATFORM is the name of the OS.
-Ideally SDL_platform.h will be able to auto-detect the system it's building
-on based on C preprocessor symbols.
-
-There are two basic ways of building SDL at the moment:
-
-1. The "UNIX" way:  ./configure; make; make install
-
-   If you have a GNUish system, then you might try this.  Edit configure.in,
-   take a look at the large section labelled:
-
-	"Set up the configuration based on the host platform!"
-
-   Add a section for your platform, and then re-run autogen.sh and build!
-
-2. Using an IDE:
-
-   If you're using an IDE or other non-configure build system, you'll probably
-   want to create a custom SDL_config.h for your platform.  Edit SDL_config.h,
-   add a section for your platform, and create a custom SDL_config_{platform}.h,
-   based on SDL_config_minimal.h and SDL_config.h.in
-
-   Add the top level include directory to the header search path, and then add
-   the following sources to the project:
-
-	src/*.c
-	src/atomic/*.c
-	src/audio/*.c
-	src/cpuinfo/*.c
-	src/events/*.c
-	src/file/*.c
-	src/haptic/*.c
-	src/joystick/*.c
-	src/power/*.c
-	src/render/*.c
-	src/render/software/*.c
-	src/stdlib/*.c
-	src/thread/*.c
-	src/timer/*.c
-	src/video/*.c
-	src/audio/disk/*.c
-	src/audio/dummy/*.c
-	src/filesystem/dummy/*.c
-	src/video/dummy/*.c
-	src/haptic/dummy/*.c
-	src/joystick/dummy/*.c
-	src/main/dummy/*.c
-	src/thread/generic/*.c
-	src/timer/dummy/*.c
-	src/loadso/dummy/*.c
-
-
-Once you have a working library without any drivers, you can go back to each
-of the major subsystems and start implementing drivers for your platform.
-
-If you have any questions, don't hesitate to ask on the SDL mailing list:
-	http://www.libsdl.org/mailing-list.php
-
-Enjoy!

-================================================================================
-
-* Works without X11
-* Hardware accelerated OpenGL ES 2.x
-* Sound via ALSA
-* Input (mouse/keyboard/joystick) via EVDEV
-* Hotplugging of input devices via UDEV
-
-
-================================================================================
- Raspbian Build Dependencies
-================================================================================
-
-sudo apt-get install libudev-dev libasound2-dev libdbus-1-dev
-
-You also need the VideoCore binary stuff that ships in /opt/vc for EGL and 
-OpenGL ES 2.x, it usually comes pre-installed, but in any case:
-    
-sudo apt-get install libraspberrypi0 libraspberrypi-bin libraspberrypi-dev
-
-================================================================================
- Cross compiling from x86 Linux
-================================================================================
-
-To cross compile SDL for Raspbian from your desktop machine, you'll need a
-Raspbian system root and the cross compilation tools. We'll assume these tools
-will be placed in /opt/rpi-tools
-
-    sudo git clone --depth 1 https://github.com/raspberrypi/tools /opt/rpi-tools
-
-You'll also need a Raspbian binary image.
-Get it from: http://downloads.raspberrypi.org/raspbian_latest 
-After unzipping, you'll get file with a name like: "<date>-wheezy-raspbian.img"
-Let's assume the sysroot will be built in /opt/rpi-sysroot.
-
-    export SYSROOT=/opt/rpi-sysroot
-    sudo kpartx -a -v <path_to_raspbian_image>.img

-
-Now, before chrooting into the ARM sysroot, you'll need to apply a workaround,
-edit $SYSROOT/etc/ld.so.preload and comment out all lines in it.

-The final step is compiling SDL itself.
-
-    export CC="/opt/rpi-tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf-gcc --sysroot=$SYSROOT -I$SYSROOT/opt/vc/include -I$SYSROOT/usr/include -I$SYSROOT/opt/vc/include/interface/vcos/pthreads -I$SYSROOT/opt/vc/include/interface/vmcs_host/linux"
-    cd <SDL SOURCE>
-    mkdir -p build;cd build
-    LDFLAGS="-L$SYSROOT/opt/vc/lib" ../configure --with-sysroot=$SYSROOT --host=arm-raspberry-linux-gnueabihf --prefix=$PWD/rpi-sdl2-installed --disable-pulseaudio --disable-esd
-    make
-    make install
-
-To be able to deploy this to /usr/local in the Raspbian system you need to fix up a few paths:
-    
-    perl -w -pi -e "s#$PWD/rpi-sdl2-installed#/usr/local#g;" ./rpi-sdl2-installed/lib/libSDL2.la ./rpi-sdl2-installed/lib/pkgconfig/sdl2.pc ./rpi-sdl2-installed/bin/sdl2-config
-    
-================================================================================
- Apps don't work or poor video/audio performance
-================================================================================
-
-If you get sound problems, buffer underruns, etc, run "sudo rpi-update" to 
-update the RPi's firmware. Note that doing so will fix these problems, but it
-will also render the CMA - Dynamic Memory Split functionality useless.
-
-Also, by default the Raspbian distro configures the GPU RAM at 64MB, this is too
-low in general, specially if a 1080p TV is hooked up.
-
-See here how to configure this setting: http://elinux.org/RPiconfig
-
-Using a fixed gpu_mem=128 is the best option (specially if you updated the 
-firmware, using CMA probably won't work, at least it's the current case).
-
-================================================================================
- No input
-================================================================================
-
-Make sure you belong to the "input" group.
-
-    sudo usermod -aG input `whoami`
-
-================================================================================
- No HDMI Audio
-================================================================================
-
-If you notice that ALSA works but there's no audio over HDMI, try adding:
-    
-    hdmi_drive=2
-    
-to your config.txt file and reboot.
-
-Reference: http://www.raspberrypi.org/phpBB3/viewtopic.php?t=5062
-
-================================================================================
- Text Input API support
-================================================================================
-
-The Text Input API is supported, with translation of scan codes done via the
-kernel symbol tables. For this to work, SDL needs access to a valid console.
-If you notice there's no SDL_TEXTINPUT message being emitted, double check that
-your app has read access to one of the following:
-    
-* /proc/self/fd/0
-* /dev/tty
-* /dev/tty[0...6]
-* /dev/vc/0
-* /dev/console
-
-This is usually not a problem if you run from the physical terminal (as opposed
-to running from a pseudo terminal, such as via SSH). If running from a PTS, a 
-quick workaround is to run your app as root or add yourself to the tty group,
-then re-login to the system.
-
-    sudo usermod -aG tty `whoami`
-    
-The keyboard layout used by SDL is the same as the one the kernel uses.
-To configure the layout on Raspbian:
-    
-    sudo dpkg-reconfigure keyboard-configuration
-    
-To configure the locale, which controls which keys are interpreted as letters,
-this determining the CAPS LOCK behavior:
-
-    sudo dpkg-reconfigure locales
-
-================================================================================
- OpenGL problems
-================================================================================
-
-If you have desktop OpenGL headers installed at build time in your RPi or cross 
-compilation environment, support for it will be built in. However, the chipset 
-does not actually have support for it, which causes issues in certain SDL apps 
-since the presence of OpenGL support supersedes the ES/ES2 variants.
-The workaround is to disable OpenGL at configuration time:
-
-    ./configure --disable-video-opengl
-
-Or if the application uses the Render functions, you can use the SDL_RENDER_DRIVER
-environment variable:
-
-    export SDL_RENDER_DRIVER=opengles2
-
-================================================================================
- Notes
-================================================================================
-
-* When launching apps remotely (via SSH), SDL can prevent local keystrokes from
-  leaking into the console only if it has root privileges. Launching apps locally
-  does not suffer from this issue.
-

-Touch
-===========================================================================
-System Specific Notes
-===========================================================================
-Linux:
-The linux touch system is currently based off event streams, and proc/bus/devices. The active user must be given permissions to read /dev/input/TOUCHDEVICE, where TOUCHDEVICE is the event stream for your device. Currently only Wacom tablets are supported. If you have an unsupported tablet contact me at jim.tla+sdl_touch@gmail.com and I will help you get support for it.
-
-Mac:
-The Mac and iPhone APIs are pretty. If your touch device supports them then you'll be fine. If it doesn't, then there isn't much we can do.
-
-iPhone: 
-Works out of box.
-
-Windows:
-Unfortunately there is no windows support as of yet. Support for Windows 7 is planned, but we currently have no way to test. If you have a Windows 7 WM_TOUCH supported device, and are willing to help test please contact me at jim.tla+sdl_touch@gmail.com
-
-===========================================================================
-Events
-===========================================================================
-SDL_FINGERDOWN:
-Sent when a finger (or stylus) is placed on a touch device.
-Fields:
-* event.tfinger.touchId  - the Id of the touch device.
-* event.tfinger.fingerId - the Id of the finger which just went down.
-* event.tfinger.x        - the x coordinate of the touch (0..1)
-* event.tfinger.y        - the y coordinate of the touch (0..1)
-* event.tfinger.pressure - the pressure of the touch (0..1)
-
-SDL_FINGERMOTION:
-Sent when a finger (or stylus) is moved on the touch device.
-Fields:
-Same as SDL_FINGERDOWN but with additional:
-* event.tfinger.dx       - change in x coordinate during this motion event.
-* event.tfinger.dy       - change in y coordinate during this motion event.
-
-SDL_FINGERUP:
-Sent when a finger (or stylus) is lifted from the touch device.
-Fields:
-Same as SDL_FINGERDOWN.
-
-
-===========================================================================
-Functions
-===========================================================================
-SDL provides the ability to access the underlying SDL_Finger structures.
-These structures should _never_ be modified.
-
-The following functions are included from SDL_touch.h
-
-To get a SDL_TouchID call SDL_GetTouchDevice(int index).
-This returns a SDL_TouchID.
-IMPORTANT: If the touch has been removed, or there is no touch with the given index, SDL_GetTouchDevice() will return 0. Be sure to check for this!
-
-The number of touch devices can be queried with SDL_GetNumTouchDevices().
-
-A SDL_TouchID may be used to get pointers to SDL_Finger.
-
-SDL_GetNumTouchFingers(touchID) may be used to get the number of fingers currently down on the device.
-
-The most common reason to access SDL_Finger is to query the fingers outside the event. In most cases accessing the fingers is using the event. This would be accomplished by code like the following:
-
-      float x = event.tfinger.x;
-      float y = event.tfinger.y;
-
-
-
-To get a SDL_Finger, call SDL_GetTouchFinger(SDL_TouchID touchID, int index), where touchID is a SDL_TouchID, and index is the requested finger.
-This returns a SDL_Finger *, or NULL if the finger does not exist, or has been removed.
-A SDL_Finger is guaranteed to be persistent for the duration of a touch, but it will be de-allocated as soon as the finger is removed. This occurs when the SDL_FINGERUP event is _added_ to the event queue, and thus _before_ the SDL_FINGERUP event is polled.
-As a result, be very careful to check for NULL return values.
-
-A SDL_Finger has the following fields:
-* x, y:
-	The current coordinates of the touch.
-* pressure:
-	The pressure of the touch.

-================================================================================

-================================================================================
-OpenGL ES 2.x support
-================================================================================
-
-SDL has support for OpenGL ES 2.x under Windows via two alternative 
-implementations. 
-The most straightforward method consists in running your app in a system with 
-a graphic card paired with a relatively recent (as of November of 2013) driver 
-which supports the WGL_EXT_create_context_es2_profile extension. Vendors known 
-to ship said extension on Windows currently include nVidia and Intel.
-
-The other method involves using the ANGLE library (https://code.google.com/p/angleproject/)
-If an OpenGL ES 2.x context is requested and no WGL_EXT_create_context_es2_profile
-extension is found, SDL will try to load the libEGL.dll library provided by
-ANGLE.
-To obtain the ANGLE binaries, you can either compile from source from
-https://chromium.googlesource.com/angle/angle or copy the relevant binaries from
-a recent Chrome/Chromium install for Windows. The files you need are:
-    
-    * libEGL.dll
-    * libGLESv2.dll
-    * d3dcompiler_46.dll (supports Windows Vista or later, better shader compiler)
-    or...
-    * d3dcompiler_43.dll (supports Windows XP or later)
-    
-If you compile ANGLE from source, you can configure it so it does not need the
-d3dcompiler_* DLL at all (for details on this, see their documentation). 
-However, by default SDL will try to preload the d3dcompiler_46.dll to
-comply with ANGLE's requirements. If you wish SDL to preload d3dcompiler_43.dll (to
-support Windows XP) or to skip this step at all, you can use the 
-SDL_HINT_VIDEO_WIN_D3DCOMPILER hint (see SDL_hints.h for more details).
-
-Known Bugs:
-    
-    * SDL_GL_SetSwapInterval is currently a no op when using ANGLE. It appears
-      that there's a bug in the library which prevents the window contents from
-      refreshing if this is set to anything other than the default value.
-     
-Vulkan Surface Support
-==============
-
-Support for creating Vulkan surfaces is configured on by default. To disable it change the value of `SDL_VIDEO_VULKAN` to 0 in `SDL_config_windows.h`. You must install the [Vulkan SDK](https://www.lunarg.com/vulkan-sdk/) in order to use Vulkan graphics in your application.

-WinRT
-=====
-
-This port allows SDL applications to run on Microsoft's platforms that require
-use of "Windows Runtime", aka. "WinRT", APIs.  Microsoft may, in some cases,
-refer to them as either "Windows Store", or for Windows 10, "UWP" apps.
-
-Some of the operating systems that include WinRT, are:
-
-* Windows 10, via its Universal Windows Platform (UWP) APIs
-* Windows 8.x
-* Windows RT 8.x (aka. Windows 8.x for ARM processors)
-* Windows Phone 8.x
-
-
-Requirements
-------------
-
-* Microsoft Visual C++ (aka Visual Studio), either 2017, 2015, 2013, or 2012
-  - Free, "Community" or "Express" editions may be used, so long as they
-    include  support for either "Windows Store" or "Windows Phone" apps.
-    "Express" versions marked as supporting "Windows Desktop" development
-    typically do not include support for creating WinRT apps, to note.
-    (The "Community" editions of Visual C++ do, however, support both
-    desktop/Win32 and WinRT development).
-  - Visual Studio 2017 can be used, however it is recommented that you install
-    the Visual C++ 2015 build tools.  These build tools can be installed
-    using VS 2017's installer.  Be sure to also install the workload for
-    "Universal Windows Platform development", its optional component, the
-    "C++ Universal Windows Platform tools", and for UWP / Windows 10
-    development, the "Windows 10 SDK (10.0.10240.0)".  Please note that
-    targeting UWP / Windows 10 apps from development machine(s) running
-    earlier versions of Windows, such as Windows 7, is not always supported
-    by Visual Studio, and you may get error(s) when attempting to do so.
-  - Visual C++ 2012 can only build apps that target versions 8.0 of Windows,
-    or  Windows Phone.  8.0-targetted apps will run on devices running 8.1
-    editions of Windows, however they will not be able to take advantage of
-    8.1-specific features.
-  - Visual C++ 2013 cannot create app projects that target Windows 8.0.
-    Visual C++ 2013 Update 4, can create app projects for Windows Phone 8.0,
-    Windows Phone 8.1, and Windows 8.1, but not Windows 8.0.  An optional
-    Visual Studio add-in, "Tools for Maintaining Store apps for Windows 8",
-    allows Visual C++ 2013 to load and build Windows 8.0 projects that were
-    created with Visual C++ 2012, so long as Visual C++ 2012 is installed
-    on the same machine.  More details on targeting different versions of
-    Windows can found at the following web pages:
-      - [Develop apps by using Visual Studio 2013](http://msdn.microsoft.com/en-us/library/windows/apps/br211384.aspx)
-      - [To add the Tools for Maintaining Store apps for Windows 8](http://msdn.microsoft.com/en-us/library/windows/apps/dn263114.aspx#AddMaintenanceTools)
-* A valid Microsoft account - This requirement is not imposed by SDL, but
-  rather by Microsoft's Visual C++ toolchain.  This is required to launch or 
-  debug apps.
-
-
-Status
-------
-
-Here is a rough list of what works, and what doens't:
-
-* What works:
-  * compilation via Visual C++ 2012 through 2015
-  * compile-time platform detection for SDL programs.  The C/C++ #define,
-    `__WINRT__`, will be set to 1 (by SDL) when compiling for WinRT.
-  * GPU-accelerated 2D rendering, via SDL_Renderer.
-  * OpenGL ES 2, via the ANGLE library (included separately from SDL)
-  * software rendering, via either SDL_Surface (optionally in conjunction with
-    SDL_GetWindowSurface() and SDL_UpdateWindowSurface()) or via the
-    SDL_Renderer APIs
-  * threads
-  * timers (via SDL_GetTicks(), SDL_AddTimer(), SDL_GetPerformanceCounter(),
-    SDL_GetPerformanceFrequency(), etc.)
-  * file I/O via SDL_RWops
-  * mouse input  (unsupported on Windows Phone)
-  * audio, via a modified version of SDL's XAudio2 backend
-  * .DLL file loading.  Libraries *MUST* be packaged inside applications.  Loading
-    anything outside of the app is not supported.
-  * system path retrieval via SDL's filesystem APIs
-  * game controllers.  Support is provided via the SDL_Joystick and
-    SDL_GameController APIs, and is backed by Microsoft's XInput API.  Please
-    note, however, that Windows limits game-controller support in UWP apps to,
-    "Xbox compatible controllers" (many controllers that work in Win32 apps,
-    do not work in UWP, due to restrictions in UWP itself.) 
-  * multi-touch input
-  * app events.  SDL_APP_WILLENTER* and SDL_APP_DIDENTER* events get sent out as
-    appropriate.
-  * window events
-  * using Direct3D 11.x APIs outside of SDL.  Non-XAML / Direct3D-only apps can
-    choose to render content directly via Direct3D, using SDL to manage the
-    internal WinRT window, as well as input and audio.  (Use
-    SDL_GetWindowWMInfo() to get the WinRT 'CoreWindow', and pass it into
-    IDXGIFactory2::CreateSwapChainForCoreWindow() as appropriate.)
-
-* What partially works:
-  * keyboard input.  Most of WinRT's documented virtual keys are supported, as
-    well as many keys with documented hardware scancodes.  Converting
-    SDL_Scancodes to or from SDL_Keycodes may not work, due to missing APIs
-    (MapVirtualKey()) in Microsoft's Windows Store / UWP APIs.
-  * SDLmain.  WinRT uses a different signature for each app's main() function.
-    SDL-based apps that use this port must compile in SDL_winrt_main_NonXAML.cpp
-    (in `SDL\src\main\winrt\`) directly in order for their C-style main()
-    functions to be called.
-
-* What doesn't work:
-  * compilation with anything other than Visual C++
-  * programmatically-created custom cursors.  These don't appear to be supported
-    by WinRT.  Different OS-provided cursors can, however, be created via
-    SDL_CreateSystemCursor() (unsupported on Windows Phone)
-  * SDL_WarpMouseInWindow() or SDL_WarpMouseGlobal().  This are not currently
-    supported by WinRT itself.
-  * joysticks and game controllers that either are not supported by
-    Microsoft's XInput API, or are not supported within UWP apps (many
-    controllers that work in Win32, do not work in UWP, due to restrictions in
-    UWP itself).
-  * turning off VSync when rendering on Windows Phone.  Attempts to turn VSync
-    off on Windows Phone result either in Direct3D not drawing anything, or it
-    forcing VSync back on.  As such, SDL_RENDERER_PRESENTVSYNC will always get
-    turned-on on Windows Phone.  This limitation is not present in non-Phone
-    WinRT (such as Windows 8.x), where turning off VSync appears to work.
-  * probably anything else that's not listed as supported
-
-
-
-Upgrade Notes
--------------
-
-#### SDL_GetPrefPath() usage when upgrading WinRT apps from SDL 2.0.3
-
-SDL 2.0.4 fixes two bugs found in the WinRT version of SDL_GetPrefPath().
-The fixes may affect older, SDL 2.0.3-based apps' save data.  Please note
-that these changes only apply to SDL-based WinRT apps, and not to apps for
-any other platform.
-
-1. SDL_GetPrefPath() would return an invalid path, one in which the path's
-   directory had not been created.  Attempts to create files there
-   (via fopen(), for example), would fail, unless that directory was
-   explicitly created beforehand.
-
-2. SDL_GetPrefPath(), for non-WinPhone-based apps, would return a path inside
-   a WinRT 'Roaming' folder, the contents of which get automatically
-   synchronized across multiple devices.  This process can occur while an
-   application runs, and can cause existing save-data to be overwritten
-   at unexpected times, with data from other devices.  (Windows Phone apps
-   written with SDL 2.0.3 did not utilize a Roaming folder, due to API
-   restrictions in Windows Phone 8.0).
-
-
-SDL_GetPrefPath(), starting with SDL 2.0.4, addresses these by:
-
-1. making sure that SDL_GetPrefPath() returns a directory in which data
-   can be written to immediately, without first needing to create directories.
-
-2. basing SDL_GetPrefPath() off of a different, non-Roaming folder, the
-   contents of which do not automatically get synchronized across devices
-   (and which require less work to use safely, in terms of data integrity).
-
-Apps that wish to get their Roaming folder's path can do so either by using
-SDL_WinRTGetFSPathUTF8(), SDL_WinRTGetFSPathUNICODE() (which returns a
-UCS-2/wide-char string), or directly through the WinRT class,
-Windows.Storage.ApplicationData.
-
-
-
-Setup, High-Level Steps
------------------------
-
-The steps for setting up a project for an SDL/WinRT app looks like the
-following, at a high-level:
-
-1. create a new Visual C++ project using Microsoft's template for a,
-   "Direct3D App".
-2. remove most of the files from the project.
-3. make your app's project directly reference SDL/WinRT's own Visual C++
-   project file, via use of Visual C++'s "References" dialog.  This will setup
-   the linker, and will copy SDL's .dll files to your app's final output.
-4. adjust your app's build settings, at minimum, telling it where to find SDL's
-   header files.
-5. add files that contains a WinRT-appropriate main function, along with some
-   data to make sure mouse-cursor-hiding (via SDL_ShowCursor(SDL_DISABLE) calls)
-   work properly.
-6. add SDL-specific app code.
-7. build and run your app.
-
-
-Setup, Detailed Steps
----------------------
-
-### 1. Create a new project ###
-
-Create a new project using one of Visual C++'s templates for a plain, non-XAML,
-"Direct3D App" (XAML support for SDL/WinRT is not yet ready for use).  If you
-don't see one of these templates, in Visual C++'s 'New Project' dialog, try
-using the textbox titled, 'Search Installed Templates' to look for one.
-
-
-### 2. Remove unneeded files from the project ###
-
-In the new project, delete any file that has one of the following extensions:
-
-- .cpp
-- .h
-- .hlsl
-
-When you are done, you should be left with a few files, each of which will be a
-necessary part of your app's project.  These files will consist of:
-
-- an .appxmanifest file, which contains metadata on your WinRT app.  This is
-  similar to an Info.plist file on iOS, or an AndroidManifest.xml on Android.
-- a few .png files, one of which is a splash screen (displayed when your app
-  launches), others are app icons.
-- a .pfx file, used for code signing purposes.
-
-
-### 3. Add references to SDL's project files ###
-
-SDL/WinRT can be built in multiple variations, spanning across three different
-CPU architectures (x86, x64, and ARM) and two different configurations
-(Debug and Release).  WinRT and Visual C++ do not currently provide a means
-for combining multiple variations of one library into a single file.
-Furthermore, it does not provide an easy means for copying pre-built .dll files
-into your app's final output (via Post-Build steps, for example).  It does,
-however, provide a system whereby an app can reference the MSVC projects of
-libraries such that, when the app is built:
-
-1. each library gets built for the appropriate CPU architecture(s) and WinRT
-   platform(s).
-2. each library's output, such as .dll files, get copied to the app's build 
-   output.
-
-To set this up for SDL/WinRT, you'll need to run through the following steps:
-
-1. open up the Solution Explorer inside Visual C++ (under the "View" menu, then
-   "Solution Explorer")
-2. right click on your app's solution.
-3. navigate to "Add", then to "Existing Project..."
-4. find SDL/WinRT's Visual C++ project file and open it.  Different project
-   files exist for different WinRT platforms.  All of them are in SDL's
-   source distribution, in the following directories:
-    * `VisualC-WinRT/UWP_VS2015/`        - for Windows 10 / UWP apps
-    * `VisualC-WinRT/WinPhone81_VS2013/` - for Windows Phone 8.1 apps
-    * `VisualC-WinRT/WinRT80_VS2012/`    - for Windows 8.0 apps
-    * `VisualC-WinRT/WinRT81_VS2013/`    - for Windows 8.1 apps
-5. once the project has been added, right-click on your app's project and
-   select, "References..."
-6. click on the button titled, "Add New Reference..."
-7. check the box next to SDL
-8. click OK to close the dialog
-9. SDL will now show up in the list of references.  Click OK to close that
-   dialog.
-
-Your project is now linked to SDL's project, insofar that when the app is
-built, SDL will be built as well, with its build output getting included with
-your app.
-
-
-### 4. Adjust Your App's Build Settings ###
-
-Some build settings need to be changed in your app's project.  This guide will
-outline the following:
-
-- making sure that the compiler knows where to find SDL's header files
-- **Optional for C++, but NECESSARY for compiling C code:** telling the
-  compiler not to use Microsoft's C++ extensions for WinRT development.
-- **Optional:** telling the compiler not generate errors due to missing
-  precompiled header files.
-
-To change these settings:
-
-1. right-click on the project
-2. choose "Properties"
-3. in the drop-down box next to "Configuration", choose, "All Configurations"
-4. in the drop-down box next to "Platform", choose, "All Platforms"
-5. in the left-hand list, expand the "C/C++" section
-6. select "General"
-7. edit the "Additional Include Directories" setting, and add a path to SDL's
-   "include" directory
-8. **Optional: to enable compilation of C code:** change the setting for
-   "Consume Windows Runtime Extension" from "Yes (/ZW)" to "No".  If you're 
-   working with a completely C++ based project, this step can usually be 
-   omitted.
-9. **Optional: to disable precompiled headers (which can produce 
-   'stdafx.h'-related build errors, if setup incorrectly:** in the left-hand 
-   list, select "Precompiled Headers", then change the setting for "Precompiled 
-   Header" from "Use (/Yu)" to "Not Using Precompiled Headers".
-10. close the dialog, saving settings, by clicking the "OK" button
-
-
-### 5. Add a WinRT-appropriate main function, and a blank-cursor image, to the app. ###
-
-A few files should be included directly in your app's MSVC project, specifically:
-1. a WinRT-appropriate main function (which is different than main() functions on
-   other platforms)
-2. a Win32-style cursor resource, used by SDL_ShowCursor() to hide the mouse cursor
-   (if and when the app needs to do so).  *If this cursor resource is not
-   included, mouse-position reporting may fail if and when the cursor is
-   hidden, due to possible bugs/design-oddities in Windows itself.*
-
-To include these files:
-
-1. right-click on your project (again, in Visual C++'s Solution Explorer), 
-   navigate to "Add", then choose "Existing Item...".
-2. navigate to the directory containing SDL's source code, then into its
-   subdirectory, 'src/main/winrt/'.  Select, then add, the following files:
-   - `SDL_winrt_main_NonXAML.cpp`
-   - `SDL2-WinRTResources.rc`
-   - `SDL2-WinRTResource_BlankCursor.cur`
-3. right-click on the file `SDL_winrt_main_NonXAML.cpp` (as listed in your
-   project), then click on "Properties...".
-4. in the drop-down box next to "Configuration", choose, "All Configurations"
-5. in the drop-down box next to "Platform", choose, "All Platforms"
-6. in the left-hand list, click on "C/C++"
-7. change the setting for "Consume Windows Runtime Extension" to "Yes (/ZW)".
-8. click the OK button.  This will close the dialog.
-
-
-**NOTE: C++/CX compilation is currently required in at least one file of your 
-app's project.  This is to make sure that Visual C++'s linker builds a 'Windows 
-Metadata' file (.winmd) for your app.  Not doing so can lead to build errors.**
-
-
-### 6. Add app code and assets ###
-
-At this point, you can add in SDL-specific source code.  Be sure to include a 
-C-style main function (ie: `int main(int argc, char *argv[])`).  From there you 
-should be able to create a single `SDL_Window` (WinRT apps can only have one 
-window, at present), as well as an `SDL_Renderer`.  Direct3D will be used to 
-draw content.  Events are received via SDL's usual event functions 
-(`SDL_PollEvent`, etc.)  If you have a set of existing source files and assets, 
-you can start adding them to the project now.  If not, or if you would like to 
-make sure that you're setup correctly, some short and simple sample code is 
-provided below.
-
-
-#### 6.A. ... when creating a new app ####
-
-If you are creating a new app (rather than porting an existing SDL-based app), 
-or if you would just like a simple app to test SDL/WinRT with before trying to 
-get existing code working, some working SDL/WinRT code is provided below.  To 
-set this up:
-
-1. right click on your app's project
-2. select Add, then New Item.  An "Add New Item" dialog will show up.
-3. from the left-hand list, choose "Visual C++"
-4. from the middle/main list, choose "C++ File (.cpp)"
-5. near the bottom of the dialog, next to "Name:", type in a name for your 
-source file, such as, "main.cpp".
-6. click on the Add button.  This will close the dialog, add the new file to 
-your project, and open the file in Visual C++'s text editor.
-7. Copy and paste the following code into the new file, then save it.
-
-
-    #include <SDL.h>
-    
-    int main(int argc, char **argv)
-    {
-        SDL_DisplayMode mode;
-        SDL_Window * window = NULL;
-        SDL_Renderer * renderer = NULL;
-        SDL_Event evt;
-    
-        if (SDL_Init(SDL_INIT_VIDEO) != 0) {
-            return 1;
-        }
-    
-        if (SDL_GetCurrentDisplayMode(0, &mode) != 0) {
-            return 1;
-        }
-    
-        if (SDL_CreateWindowAndRenderer(mode.w, mode.h, SDL_WINDOW_FULLSCREEN, &window, &renderer) != 0) {
-            return 1;
-        }
-    
-        while (1) {
-            while (SDL_PollEvent(&evt)) {
-            }
-    
-            SDL_SetRenderDrawColor(renderer, 0, 255, 0, 255);
-            SDL_RenderClear(renderer);
-            SDL_RenderPresent(renderer);
-        }
-    }
-
-
-#### 6.B. Adding code and assets ####
-
-If you have existing code and assets that you'd like to add, you should be able 
-to add them now.  The process for adding a set of files is as such.
-
-1. right click on the app's project
-2. select Add, then click on "New Item..."
-3. open any source, header, or asset files as appropriate.  Support for C and 
-C++ is available.
-
-Do note that WinRT only supports a subset of the APIs that are available to 
-Win32-based apps.  Many portions of the Win32 API and the C runtime are not 
-available.
-
-A list of unsupported C APIs can be found at 
-<http://msdn.microsoft.com/en-us/library/windows/apps/jj606124.aspx>
-
-General information on using the C runtime in WinRT can be found at 
-<https://msdn.microsoft.com/en-us/library/hh972425.aspx>
-
-A list of supported Win32 APIs for WinRT apps can be found at 
-<http://msdn.microsoft.com/en-us/library/windows/apps/br205757.aspx>.  To note, 
-the list of supported Win32 APIs for Windows Phone 8.0 is different.  
-That list can be found at 
-<http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj662956(v=vs.105).aspx>
-
-
-### 7. Build and run your app ###
-
-Your app project should now be setup, and you should be ready to build your app.  
-To run it on the local machine, open the Debug menu and choose "Start 
-Debugging".  This will build your app, then run your app full-screen.  To switch 
-out of your app, press the Windows key.  Alternatively, you can choose to run 
-your app in a window.  To do this, before building and running your app, find 
-the drop-down menu in Visual C++'s toolbar that says, "Local Machine".  Expand 
-this by clicking on the arrow on the right side of the list, then click on 
-Simulator.  Once you do that, any time you build and run the app, the app will 
-launch in window, rather than full-screen.
-
-
-#### 7.A. Running apps on older, ARM-based, "Windows RT" devices ####
-
-**These instructions do not include Windows Phone, despite Windows Phone
-typically running on ARM processors.**  They are specifically for devices
-that use the "Windows RT" operating system, which was a modified version of
-Windows 8.x that ran primarily on ARM-based tablet computers.
-
-To build and run the app on ARM-based, "Windows RT" devices, you'll need to:
-
-- install Microsoft's "Remote Debugger" on the device.  Visual C++ installs and 
-  debugs ARM-based apps via IP networks.
-- change a few options on the development machine, both to make sure it builds 
-  for ARM (rather than x86 or x64), and to make sure it knows how to find the 
-  Windows RT device (on the network).
-
-Microsoft's Remote Debugger can be found at 
-<https://msdn.microsoft.com/en-us/library/hh441469.aspx>.  Please note 
-that separate versions of this debugger exist for different versions of Visual 
-C++, one each for MSVC 2015, 2013, and 2012.
-
-To setup Visual C++ to launch your app on an ARM device:
-
-1. make sure the Remote Debugger is running on your ARM device, and that it's on 
-   the same IP network as your development machine.
-2. from Visual C++'s toolbar, find a drop-down menu that says, "Win32".  Click 
-   it, then change the value to "ARM".
-3. make sure Visual C++ knows the hostname or IP address of the ARM device.  To 
-   do this:
-    1. open the app project's properties
-    2. select "Debugging"
-    3. next to "Machine Name", enter the hostname or IP address of the ARM 
-       device
-    4. if, and only if, you've turned off authentication in the Remote Debugger,
-       then change the setting for "Require Authentication" to No
-    5. click "OK"
-4. build and run the app (from Visual C++).  The first time you do this, a 
-   prompt will show up on the ARM device, asking for a Microsoft Account.  You 
-   do, unfortunately, need to log in here, and will need to follow the 
-   subsequent registration steps in order to launch the app.  After you do so, 
-   if the app didn't already launch, try relaunching it again from within Visual 
-   C++.
-
-
-Troubleshooting
----------------
-
-#### Build fails with message, "error LNK2038: mismatch detected for 'vccorlib_lib_should_be_specified_before_msvcrt_lib_to_linker'"
-
-Try adding the following to your linker flags.  In MSVC, this can be done by
-right-clicking on the app project, navigating to Configuration Properties ->
-Linker -> Command Line, then adding them to the Additional Options
-section.
-
-* For Release builds / MSVC-Configurations, add:
-
-    /nodefaultlib:vccorlib /nodefaultlib:msvcrt vccorlib.lib msvcrt.lib
-
-* For Debug builds / MSVC-Configurations, add:
-
-    /nodefaultlib:vccorlibd /nodefaultlib:msvcrtd vccorlibd.lib msvcrtd.lib
-
-
-#### Mouse-motion events fail to get sent, or SDL_GetMouseState() fails to return updated values
-
-This may be caused by a bug in Windows itself, whereby hiding the mouse
-cursor can cause mouse-position reporting to fail.
-
-SDL provides a workaround for this, but it requires that an app links to a
-set of Win32-style cursor image-resource files.  A copy of suitable resource
-files can be found in `src/main/winrt/`.  Adding them to an app's Visual C++
-project file should be sufficient to get the app to use them.
-
-
-#### SDL's Visual Studio project file fails to open, with message, "The system can't find the file specified."
-
-This can be caused for any one of a few reasons, which Visual Studio can
-report, but won't always do so in an up-front manner.
-
-To help determine why this error comes up:
-
-1. open a copy of Visual Studio without opening a project file.  This can be
-   accomplished via Windows' Start Menu, among other means.
-2. show Visual Studio's Output window.  This can be done by going to VS'
-   menu bar, then to View, and then to Output.
-3. try opening the SDL project file directly by going to VS' menu bar, then
-   to File, then to Open, then to Project/Solution.  When a File-Open dialog
-   appears, open the SDL project (such as the one in SDL's source code, in its
-   directory, VisualC-WinRT/UWP_VS2015/).
-4. after attempting to open SDL's Visual Studio project file, additional error
-   information will be output to the Output window.
-
-If Visual Studio reports (via its Output window) that the project:
-
-"could not be loaded because it's missing install components. To fix this launch Visual Studio setup with the following selections:
-Microsoft.VisualStudio.ComponentGroup.UWP.VC"
-
-... then you will need to re-launch Visual Studio's installer, and make sure that
-the workflow for "Universal Windows Platform development" is checked, and that its
-optional component, "C++ Universal Windows Platform tools" is also checked.  While
-you are there, if you are planning on targeting UWP / Windows 10, also make sure
-that you check the optional component, "Windows 10 SDK (10.0.10240.0)".  After
-making sure these items are checked as-appropriate, install them.
-
-Once you install these components, try re-launching Visual Studio, and re-opening
-the SDL project file.  If you still get the error dialog, try using the Output
-window, again, seeing what Visual Studio says about it.
-
-
-#### Game controllers / joysticks aren't working!
-
-Windows only permits certain game controllers and joysticks to work within
-WinRT / UWP apps.  Even if a game controller or joystick works in a Win32
-app, that device is not guaranteed to work inside a WinRT / UWP app.
-
-According to Microsoft, "Xbox compatible controllers" should work inside
-UWP apps, potentially with more working in the future.  This includes, but
-may not be limited to, Microsoft-made Xbox controllers and USB adapters.

-Simple DirectMedia Layer {#mainpage}
-========================
-
-                                  (SDL)

-http://www.libsdl.org/
-
-Simple DirectMedia Layer is a cross-platform development library designed
-to provide low level access to audio, keyboard, mouse, joystick, and graphics
-hardware via OpenGL and Direct3D. It is used by video playback software,
-emulators, and popular games including Valve's award winning catalog
-and many Humble Bundle games.
-
-SDL officially supports Windows, Mac OS X, Linux, iOS, and Android.
-Support for other platforms may be found in the source code.
-
-SDL is written in C, works natively with C++, and there are bindings 
-available for several other languages, including C# and Python.
-
-This library is distributed under the zlib license, which can be found
-in the file "COPYING.txt".
-
-The best way to learn how to use SDL is to check out the header files in
-the "include" subdirectory and the programs in the "test" subdirectory.
-The header files and test programs are well commented and always up to date.
-
-More documentation and FAQs are available online at [the wiki](http://wiki.libsdl.org/)

- *  SDL_AtomicIncRef()
- *  SDL_AtomicDecRef()
- *
- * Seriously, here be dragons!

- *
- * There's also lots of good information here:

- * 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

- *      more audio samples to be played (or for capture devices, call
- *      SDL_DequeueAudio() with some frequency, to obtain audio samples).
- *    - \c desired->userdata is passed as the first parameter to your callback
- *      function. If you passed a NULL callback, this value is ignored.
- *
- *  The audio device starts out playing silence when it's opened, and should
- *  be enabled for playing by calling \c SDL_PauseAudio(0) when you are ready

-* 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.
-*    KHRONOS_SUPPORT_FLOAT is 1 if floats are supported; otherwise 0.
-*
-* Calling convention macros defined in this file:
-*    KHRONOS_APICALL
-*    KHRONOS_APIENTRY
-*    KHRONOS_APIATTRIBUTES
-*
-* These may be used in function prototypes as:
-*
-*      KHRONOS_APICALL void KHRONOS_APIENTRY funcname(

- * \brief Get the user-and-app-specific path where files can be written.
- *
- * Get the "pref dir". This is meant to be where users can write personal
- *  files (preferences and save games, etc) that are specific to your
- *  application. This directory is unique per user, per application.
- *
- * This function will decide the appropriate location in the native filesystem,
- *  create the directory if necessary, and return a string of the absolute
- *  path to the directory in UTF-8 encoding.
- *
- * On Windows, the string might look like:
- *  "C:\\Users\\bob\\AppData\\Roaming\\My Company\\My Program Name\\"
- *
- * On Linux, the string might look like:
- *  "/home/bob/.local/share/My Program Name/"
- *
- * On Mac OS X, the string might look like:
- *  "/Users/bob/Library/Application Support/My Program Name/"
- *
- * (etc.)
- *
- * You specify the name of your organization (if it's not a real organization,
- *  your name or an Internet domain you own might do) and the name of your
- *  application. These should be untranslated proper names.
- *
- * Both the org and app strings may become part of a directory name, so
- *  please follow these rules:
- *
- *    - Try to use the same org string (including case-sensitivity) for
- *      all your applications that use this function.
- *    - Always use a unique app string for each one, and make sure it never
- *      changes for an app once you've decided on it.
- *    - Unicode characters are legal, as long as it's UTF-8 encoded, but...
- *    - ...only use letters, numbers, and spaces. Avoid punctuation like
- *      "Game Name 2: Bad Guy's Revenge!" ... "Game Name 2" is sufficient.
- *
- * This returns an absolute path in UTF-8 encoding, and is guaranteed to
- *  end with a path separator ('\\' on Windows, '/' most other places).
- *
- * The pointer returned by this function is owned by you. Please call

- *
- * You should assume the path returned by this function is the only safe
- *  place to write files (and that SDL_GetBasePath(), while it might be
- *  writable, or even the parent of the returned path, aren't where you
- *  should be writing things).
- *
- * Some platforms can't determine the pref path, and on other
- *  platforms, this might be meaningless. In such cases, this function will
- *  return NULL.
- *
- *   \param org The name of your organization.
- *   \param app The name of your application.

-/**
- *  \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

- *  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

- *  determine the dimensions of the wave.
- *
- *  Phase is given by hundredth of a degree meaning that giving the phase a value

- *   -     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 The generic template for any haptic effect.
- *
- *  All values max at 32767 (0x7FFF).  Signed values also can be negative.
- *  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.
- *  \endcode

- *  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.
- *

- *        anything special when calling SDL.
- *
- *  \note On non-Apple devices, SDL requires you to either not link to the
- *        Vulkan loader or link to a dynamic library version. This limitation
- *        may be removed in a future version of SDL.

- * file.  In all other cases you should be protecting your data structures
- * with full mutexes.
- *
- * The list of "safe" functions to use are:

- *  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.

- *      more audio samples to be played (or for capture devices, call
- *      SDL_DequeueAudio() with some frequency, to obtain audio samples).
- *    - \c desired->userdata is passed as the first parameter to your callback
- *      function. If you passed a NULL callback, this value is ignored.
- *
- *  The audio device starts out playing silence when it's opened, and should
- *  be enabled for playing by calling \c SDL_PauseAudio(0) when you are ready

-* Adopters may modify this file to suit their platform. Adopters are
-* encouraged to submit platform specific modifications to the Khronos
-* group so that they can be included in future versions of this file.
-* Please submit changes by sending them to the public Khronos Bugzilla
-* (http://khronos.org/bugzilla) by filing a bug against product
-* "Khronos (general)" component "Registry".
-*
-* A predefined template which fills in some of the bug fields can be

-* See the Implementer's Guidelines for information about where this file
-* should be located on your system and for more details of its use:
-*    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_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_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.

- *  \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);
- *
- *    return 0; // Success
- * }

- *  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).
- *
- *

- *  from the south means the user will have to pull the stick to counteract):
- *  \code
- *  SDL_HapticDirection direction;

- *  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.

- *  A periodic effect consists in a wave-shaped effect that repeats itself

- *  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

- *      * filled rectangles
- *      * texture images
- *

- *  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.

+ * 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_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.

+ *  \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);

+ *  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).

+ *  A periodic effect consists in a wave-shaped effect that repeats itself

+ *
+ *  Phase is given by hundredth of a degree meaning that giving the phase a value

+ *   -     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

+ *  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

+ *
+ *  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
+ *        dynamic library version.

+* 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

+ *  \brief Provide a callback that decides if a window region has special properties.

+ *  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.
+ *

+  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)

+      * 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.

+ *  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

+ *  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.

+================================================
+
+The Wayland video driver has support for some additional features when

+
+The files following headers have been

+
+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

+        // 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.

-		//     section "4.3.5 Uniforms":
-		// 
-		// The link time initial value is either the value of the variable's 
-		// initializer, if present, or 0 if no initializer is present.Sampler
-		// types cannot have initializers.
-		// 
-		// Since a value of 0 means that it's sampling from texture unit 0, it will 
-		// work without ever setting the value as long as you bind your textures to
-		// unit 0. This is well defined behavior.
-		// 
-		// Since texture unit 0 is also the default until you call glActiveTexture()
-		// with a value other than GL_TEXTURE0, it's very common to always use unit 
-		// 0 as long as shaders do not need more than one texture.Which means that
-		// often times, setting the sampler uniforms is redundant for simple
-		// applications.
-		// 
-		// I would still prefer to always set the values.If nothing else, it makes

+// The default value of a sampler variable is 0. From the GLSL 3.30 spec,
+//     section "4.3.5 Uniforms":
+// 
+// The link time initial value is either the value of the variable's 
+// initializer, if present, or 0 if no initializer is present.Sampler
+// types cannot have initializers.
+// 
+// Since a value of 0 means that it's sampling from texture unit 0, it will 
+// work without ever setting the value as long as you bind your textures to
+// unit 0. This is well defined behavior.
+// 
+// Since texture unit 0 is also the default until you call glActiveTexture()
+// with a value other than GL_TEXTURE0, it's very common to always use unit 
+// 0 as long as shaders do not need more than one texture.Which means that
+// often times, setting the sampler uniforms is redundant for simple
+// applications.
+// 
+// I would still prefer to always set the values.If nothing else, it makes
+// it clear to anybody reading your code that you really mean to sample from
+// texture unit 0, and did not just forget to set the value.

-			 * Use short names because they don't make the lines in a log file too long.
-			 * 
-			 * Create names where the important part is at the beginning. Log viewers in a 
-			 * graphical user interface tend to have tables with columns, and the thread 
-			 * column is usually small or will be made small by you to read everything else.
-			 * 
-			 * Do not use the word "thread" in the thread name because it is obvious.
-			 * 
-			 * Make the thread names easily grep-able. Avoid similar sounding thread names
-			 * 
-			 * If you have several threads of the same nature, enumerate them with IDs that 
-			 * are unique to one execution of the application or one log file, whichever fits 
-			 * your logging habits.
-			 * 
-			 * Avoid generalizations like "WorkerThread" (how do you name the next 5 worker 
-			 * threads?), "GUIThread" (which GUI? is it for one window? for everything?) or 
-			 * "Calculation" (what does it calculate?).
-			 * 
-			 * If you have a test group that uses thread names to grep your application's log 
-			 * files, do not rename your threads after some time. Your testers will hate you for 
-			 * doing so. Thread names in well-tested applications should be there to stay.
-			 * 
-			 * When you have threads that service a network connection, try to include the target 
-			 * network address in the thread name (e.g. channel_123.212.123.3). Don't forget about 
-			 * enumeration though if there are multiple connections to the same host.
