This will (eventually) make SDL_GetQueuedAudioSize() more accurate, and thus
reduce latency. Right now this isn't implemented anywhere, so we assume data
fed to the audio callback is consumed by the hardware and immediately played
to completion.
For versions of XAudio2 with an IXAudio2SourceVoice::GetState() that offers a
flags parameter, we can use XAUDIO2_VOICE_NOSAMPLESPLAYED, since we don't
need this information in our current calls. According to MSDN, this makes the
the call about 3x faster.
1) Moves all READMEs to docs/
2) Renames them to *.md, adds some Markdown with the idea to add a lot more
3) Moves the doxyfile config to doc/ and makes it parse the headers at ../include as well as the md files in docs.
4) Skips SDL_opengl*.h headers from the docs
5) Minor fixes to doxyfile
This requires at least Xcode 4.5 and the iOS 6 SDK to build, but it doesn't change the minimum supported runtime version (iOS 5.1). Less than 2% of iOS users are running iOS 5, so I hope developers aren't trying to build SDL using an SDK which doesn't support iOS 6/7...

In GL_CreateTexture function:
if (GL_CheckError("glGenTexures()", renderer) < 0) {
SDL_free(data);
return -1;
}
Here only data is getting free but data->pixels getting leak.
So have to free data->pixels before free data.
Previously, SDL would always expose display modes and window dimensions in terms of pixels, and would add an extra 'fake' display mode on retina screens which would contain the non-retina resolution. Calling SDL_CreateWindow with the dimensions of that fake display mode would not work.
Now, SDL only exposes display modes and window dimensions in terms of points rather than pixels. If the SDL_WINDOW_ALLOW_HIGHDPI flag is passed into SDL_CreateWindow, then any OpenGL contexts created from that window will be sized in pixels rather than points (retrievable with SDL_GL_GetDrawableSize.) Window dimensions and mouse coordinates are still in terms of points rather than pixels even with that flag.
This matches the behavior of SDL in OS X more closely, and lets users choose whether to make use of retina displays and lets them handle it properly.

Basically this bug is probably not a common use case. My goal is to allow rendering totally without a window, for example to a screenshot and I need to rely on SDL_SetRenderTarget to properly work for a purely software renderer created by SDL_CreateSoftwareRenderer.
