Because it's so broken, I'm going to disable XRandR by default. You can still enable it via environment variable or application hint (SDL_HINT_VIDEO_X11_XRANDR)
rather than at configure time. As OS X supports lipo'ed versions of SDL for i386
and x86_64, a single set of headers that work for both architectures is desired.

currently SDL (HG) does not implement the power management functionality of
SDL_GetPowerInfo() for Android.
I attached a patch which tries to implement this functionality (JNI only, API
5). It supports plugged state and battery percent return values but not
remaining seconds (which are not available on Android).
It's a long-dead platform, and we don't have any way to build for, test, or
maintain it, so there's no sense in doing acrobatics to support it.
If you need Windows CE support, use SDL 1.2. If you need Windows Phone support,
send SDL 2.0 patches for the newer Windows Mobile platform.

With OpenGL 4.3 the ARB added a new context flag for context reset isolation
and renamed the existing ES2 profile bit to ES profile bit, as it can be used
to request GLES 3 compatible contexts, too.
This patch adds these changes to SDL on Linux and Windows.
Also SDL lacks the ability to create shared contexts. This patch also adds a
new GL attribute to enable context sharing. As casting a GL context to int is
not portable, I added only a boolean attribute
SDL_GL_SHARE_WITH_CURRENT_CONTEXT, which makes the new context share resources
with the context current on the creating thread.
I think you'll need to install Xquartz, the external-but-official replacement
for Apple's X11, to get the Xlib headers: http://support.apple.com/kb/HT5293
This required a small public API change: SDL_GL_SetSwapInterval() now accepts
negative values, and SDL_GL_GetSwapInterval() doesn't report errors anymore
(if it can't work, it'll return zero as a reasonable default).
If you need to test for errors, such as a lack of swap_control_tear support,
check the results of SDL_GL_SetSwapInterval() when you set your desired
value.

The SDL_Touch structure currently reserves fields for tablet tilt and rotation
(marked "for future use"), but a tablet stylus can tilt in both x and y
directions in addition to rotation around itself (or, put another way, it can
rotate in x, y and z). So, the struct should probably reserve fields for both
tilt_x and tilt_y, not just tilt.

Okay, I think I have something for this. Tested it on GL and GLES
machines, it seems to work okay.
- Add a new SDL GL attribute SDL_GL_CONTEXT_EGL:
- Only useful for the X11 video driver at the moment
- Set to 1 for an EGL context, 0 to use the default for the video driver
- Default is 0, unless library is built for EGL only
- Should be set after SDL init, but before window/context
creation (i.e. same place you'd specify attributes for major/minor GL
version)
- After a lot of agony pondering the least-terrible way to go about
it, made it so that X11_GL_LoadLibrary and X11_GLES_LoadLibrary check
SDL_GL_CONTEXT_EGL. If no GL context exists yet, and the attribute
choice doesn't match with the checking function, then it changes all
the function pointers in the video driver and passes control on to the
new LoadLibrary method.
- Likewise, make X11_CreateWindow check this attribute before firing
off a call to X11_GL_GetVisual/X11_GLES_GetVisual
- Added a sanity check to the start of X11_GL_LoadLibrary
- Tidied up SDL_x11opengles.h
- Moved ownership of the gles_data structure over to
X11_GLES_LoadLibrary/UnloadLibrary
- Should incorporate the 3 fixes posted by Andre Heider
This is obviously quite a bit to take in, but is (at least) a proof of
concept for the approach I think EGL/GLX mingling should take. Any
comments/criticism is much appreciated.
2.Replaced XKeycodeToKeysym with XkbKeycodeToKeysym since XKeycodeToKeysym is deprecated in newer X11 version
3.Rewrote testime.c since it was disabled after SDL_compat.c removal
4.Take into account common arguments also in testrelative.c
1.initial work on XInput2 support
2.Implemented relative mouse motion when XInput2 is enabled
3.Created a test app to test relative mouse motion
4.Fixed Bug #1498

I've updated the context creation patch to include the bugfixes by Martin
Schreiber and also included a profile bit to request a ES2 compatible profile.
The wgl context creation may use 2 call to wglChoosePixelFormat if no
acceleration attribute is selected, this should work around a bug with buggy
AMD drivers (see #1254).
