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.
If your application wants to have access to the full resolution even when the system has DPI scaling enabled, call SetProcessDPIAware() before calling SDL_Init()
e.g.
typedef BOOL (WINAPI *SetProcessDPIAware_t)(void);
HMODULE hMod = LoadLibrary("user32.dll");
if ( hMod ) {
SetProcessDPIAware_t pSetProcessDPIAware = GetProcAddress( hMod, "SetProcessDPIAware" );
if ( pSetProcessDPIAware ) {
pSetProcessDPIAware();
}
FreeLibrary( hMod );
}
To enable this, set the environment variable SDL_MOUSE_RELATIVE_MODE_WARP to "1"
When mouse relative mode is disabled, put the cursor back where the application expects it to be, instead of where it was when relative mode was enabled.
Based on the original port to Wayland by: Joel Teichroeb, Benjamin Franzke, Scott Moreau, et al.
Additional changes in this commit, done by me:
* Wayland uses the common EGL framework
* EGL can now create a desktop OpenGL context
* testgl2 loads GL functions dynamically, no need to link to libGL anymore
* Assorted fixes to the Wayland backend
Tested on the Weston Compositor (v1.0.5) that ships with Ubuntu 13.10,
running Weston under X. Tests ran: testrendercopyex (all backends), testgl2, testgles2,testintersections

SDL_ltoa(-2147483648,s,10) only returns "-" because there is a bug in the code:
if ( value < 0 ) {
*bufp++ = '-';
value = -value;
}
but -(-2147483648) is still -2147483648 (0x80000000) as signed int (or long), so the following loop doesn't run at all. Similar bug are also in SDL_lltoa.
BTW, there is no sanity check for radix.

This means everything will render black if the software rendering backend selects a pixel format that supports alpha. So it seems best to at lease assume alpha is supported.
