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

SDL_touch.c never actually uses the 'pressurein' arguments to
SDL_SendFingerDown/SDL_SendTouchMotion, so it doesn't report the real pressure.
Also it uses touch->pressureres which is never initialised. Also it fails to
initialise some fields of event.tfinger for certain events, so applications
might try to use bogus data.
The attached patch seems to be enough to produce generally sensible output on
Android.

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).

There is only one Altivec accelerated blit function
(ConvertAltivec32to32_prefetch() or ConvertAltivec32to32_noprefetch(),
depending on the CPU used) that is supposed to handle all alpha combinations.
This works as follows for every pixel line:
1. Blit single pixels until an aligned address is reached
2. Accelerated blit as far as possible
3. Blit single remaining pixels
Part 2. is set up correctly to handle different combinations of the alpha
channels of the participating surfaces. Parts 1. and 3. only do a simple copy
of all the pixel's components from souce to destination. But when the source
surface has no alpha channel (Amask is 0, e.g. the video surface) the surface's
alpha value must be used instead. Otherwise crap (uninitialized data) is being
copied to the destiniation's alpha channel.
The attached patch is a quick'n'dirty solution to the problem. A more
sophisticated solution might require separate functions for different
combinations of the alpha channels of the participating surfaces.

As alluded to in the email thread "SDL2 error on iOS (doublefree)", I believe
the original cause of this bug is confusion over the purpose of
SDL_VideoDisplay::current_mode. It looks as though it is a weak reference to
another mode, albeit with value semantics. The iOS port treated it as a strong
reference however and claimed ownership, which is why things blew up. All the
patch really does it to stop treating current_mode as a strong reference.
To prevent this happening again it might be an idea to change current_mode to
be a pointer type rather than a value. This would certainly make its semantics
much more obvious. Failing that, a comment in the struct indicating its weak
reference properties might be wise.

render/nds/SDL_libgl2D.c unconditionally includes NDS-only code. SDL's
Android.mk compiles source files matching
$(wildcard $(LOCAL_PATH)/src/render/*/*.c)
which includes that file, causing build errors when running ndk-build.

src/joystick/bsd/SDL_sysjoystick.c makes the invalid assumption that
__FreeBSD_kernel__ implies presence of "ucr_data" struct member. This
breaks recent versions of FreeBSD 10-CURRENT, FreeBSD 9-STABLE and
Debian GNU/kFreeBSD "wheezy/sid".

This patch updates the DS port:
- do not use the now removed compat layer.
- integrate parts of libgl2D since I got permission from the author, and thus
removed an external dependancy,
- a few bugs fixes.
Now, the textures should be completely supported, except reading from them
which doesn't makes sense to have on the DS. Sound is still not supported.
If someone else wants to work on the missing pieces, feel free.

Hi gus there is a bug when using software renderer and the window
surface gets destroyed (Fullscreen and back).The solution is easy
jordirovira 2012-01-28 12:07:39 PST
in SDL_x11window around 520:
/* Setup the normal size hints */
if (!(window->flags & SDL_WINDOW_RESIZABLE)) {
sizehints.min_width = sizehints.max_width = window->w;
sizehints.min_height = sizehints.max_height = window->h;
sizehints.flags = PMaxSize | PMinSize;
}
sizehints.x = window->x;
sizehints.y = window->y;
sizehints.flags |= USPosition;
the sizehints.flags member is not initizalised if it doesn't enter the
conditional. It is as easy as setting it to zero before the conditional.
From Gabriel Jacobo:
What I did notice is that calling
data->glGetIntegerv(GL_FRAMEBUFFER_BINDING_OES, &value); doesn't produce any
result in Android GLES1.1 if the active framebuffer is the default one, ie,
whatever is in value stays unmodified.
