Note that extra steps must be taken when using glReadPixels to read the contents of the main OpenGL ES framebuffer on iOS, if multisampling is used. See the OpenGL ES section of README-ios.md for details.
There are platforms it isn't implemented on (and currently can't be
implemented on!), and there's currently no way for an app to know this.
This shouldn't break ABI on apps that moved to a revision between 2.0.3 and
2.0.4.
The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly
uninitialized data structure if loading the library first failed. A later try to
use EGL then skipped initialization and assumed it was previously successful
because the data structure now already existed. This led to at least one crash
in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was
dereferenced to make a call to eglBindAPI().
Clarify that grabbing the mouse only works with one window at a time; this was
always true at the system level, though SDL could previously get confused
by multiple simultaneous grabs, so now we explicitly break any existing
grab before starting a new one and document it as such.
Also track the window that is currently grabbed, and provide an API to query
for that window. This makes it easy to automate mouse ungrabbing at
breakpoints with gdb7's scripting, since the scripts can now know which window
to ungrab.
In 2.1, we should probably change this API to SDL_GrabInput(win) and
SDL_UngrabInput(void), or something.
This extension allows the user to specify whether a full flush is performed when making a context not current.
The only way to set this currently is at context creation, so this patch provides that functionality.
Defualt behaviour is set at FLUSH, as per the spec.
This patch does not contain the changes to WGL, appleGL or other platforms as I do not have access to GL 4.5 hardware on those platforms.
Full details on the use of KHR_context_flush_control can be found here:
https://www.opengl.org/registry/specs/KHR/context_flush_control.txt
This fills in the core pieces and fully implements it for Mac OS X.
Most other platforms, at the moment, will report a disconnected device if
it fails to write audio, but don't notice if the system's device list changed
at all.
64-bit Linux uses a "long" instead of "long long" for 64-bit ints.
Added a special-case this so SDL_PRI?64 doesn't trigger compiler warnings
when used with SDL's 64-bit datatypes on 64-bit Linux.
Yes this seems confusing as on mac+linux Long is either 32 or 64bits depending on the architecture, but this is how the X11 protocol is defined. Thus 5 is the correct value for the nelts here. Not 5 or 10 depending on the architecture.

- Added new custom launch screen code. It uses the launch screen nib when available on iOS 8+, the launch images dictionary if the launch screen nib isn't available, and the old standard image names if the launch image dictionary isn't in the plist.
The launch screen is now hidden during the first call to SDL_PumpEvents rather than SDL_CreateWindow so apps can have the launch screen still visible if they do time-consuming loading after creating their window. It also fades out in roughly the same way as the system launch screen behavior.
It can be disabled by setting the SDL_IPHONE_LAUNCHSCREEN define in SDL_config_iphoneos.h to 0.
- A blank UIView is now created and displayed when the window is first created. The old behavior was to defer creating any view until SDL_GL_CreateContext, which prevented rotation, touch events, and other windowing-related things from working until then. This also makes it easier to use SDL_GetWindowWMInfo after creating a window.
- Moved the keyboard and animation callback code from SDL's UIView subclasses to its UIViewController subclass, which lets them work properly in all cases when a SDL window is valid, even before SDL_GL_CreateContext is called and after SDL_GL_DeleteContext is called.
- SDL_GL_CreateContext, SDL_GL_SwapWindow, SDL_GL_MakeCurrent, and SDL_GL_DeleteContext are more robust.
- Fixed some edge cases where SDL windows weren't rotating properly or their reported sizes were out of sync with their actual sizes.
- Removed all calls to [UIApplication setStatusBarOrientation:]. It doesn't seem to work as expected in all cases in recent iOS versions.
- Some code style cleanup.

The configure script didn't differentiate between Linux and Android, unconditionally compiling in the unix implementation of SDL_sysfilesystem.c.
I'm probably one of the very few people building SDL for android using classic configure + standalone toolchain, so this has gone undetected all along.
This is a little macro magic to use malloc() directly instead of SDL_malloc(),
etc, so static analysis tests that know about the C runtime can function
properly, and understand that we are dealing with heap allocations, etc.
This changed our static analysis report from 5 outstanding bugs to 30.
5x as many bugs were hidden by SDL_malloc() not being recognized as malloc()
by the static analyzer!
SDL_WinRTRunApp() is used on WinRT to launch a main(int, char **)-style
function. It has optional, and experimental support for launching content
inside a XAML control, backed by a main() function running on a separate thread.
This is provided via it's 2nd parameter, which can be a pointer to a XAML
control. (If NULL, XAML support will not be used.)
This change renames the experimental feature's parameter (to SDL_WinRTRunApp())
as "reserved", until such time as the functionality is ready for use. It will
likely be renamed again in the future, when running SDL on top of a XAML control
via a separate thread, becomes reasonably usable.
