The projection and view matrices are now computed ahead of time, as they both get computed in the same spot, and typically not often. If this does, however, become a performance problem later on, this change can always be reverted.
Previously, the shaders would get compiled separately, the output of which would need to be packaged into the app. This change should make SDL's dll be the only binary needed to include SDL in a WinRT app.
SDL 2.x recently accepted patches to enable OpenGL ES 2 support via Google's ANGLE library. The thought is to try to eventually merge SDL/WinRT's OpenGL code with SDL-official's.

As described in the other thread
(http://lists.libsdl.org/pipermail/sdl-libsdl.org/2013-November/091997.html),
I've run into a case of SDL2 not recognizing a wireless Xbox 360
controller receiver properly on Debian Linux amd64 testing.
Apparently, the generated GUID is slightly different.
Device in question:
Bus 001 Device 015: ID 045e:0291 Microsoft Corp. Xbox 360 Wireless
Receiver for Windows

Steps to reproduce:
1. Grab the cursor with SDL_SetCursorGrab()
2. Alt-tab away from the window
3. Click on the titlebar of the window
This will cause the window to disappear underneath the taskbar!
This appears to be a general issue with ClipCursor() on windows, i.e. I am getting the same behavior if I call ClipCursor() directly.
It is caused by a feedback loop between the ClipCursor function and the modal resize/move event loop that handles mouse-based sizing on Windows.

The SDL_ceil function is implemented incorrectly when HAVE_CEIL is not defined (HAVE_LIBC not defined).
The following code:
double val = SDL_ceil(2.3);
printf("%g", val);
prints "2.0", as STD_ceil is defined as:
double
SDL_ceil(double x)
{
#ifdef HAVE_CEIL
return ceil(x);
#else
return (double)(int)((x)+0.5);
#endif /* HAVE_CEIL */
}
This functions is used in the SDL_BuildAudioResampleCVT function of the audio subsystem (SDL_audiocvt.c), and causes a bug in that function.
Lets Android take care of which is the primary pointer (the one acting as the
mouse in SDL), reorganized the Java side code as well to make it easier to
understand.
