- Added new SDL_HINT_ALLOW_TOPMOST hint, when set to "0" then never set the topmost bit on a window. Useful when debugging fullscreen issues.
- fixed crash in windows joystick scanning if we failed to load the xinput dll
- added support for SDL_WINDOW_FULLSCREEN_DESKTOP under windows
- synthesize relative mouse movements if directinput fails to send relative moves, happens under virtual box.

When creating a SDL_Texture with unsupported format (I'll now refer to it as
texture A), SDL_CreateTexture will call SDL_CreateTexture again with
GetClosestSupportedFormat to set texture->native (which I will now refer to as
texture B).
This causes texture B to be put before A in renderer->textures.
If texture A is explicitly destroyed, everything is fine. Otherwise, upon
SDL_DestroyRenderer, the loop will first encounter texture B, destroy it, then
texture A, destroy that which will want to destroy texture->native and since it
is already destroyed set an error.
The solution could be as simple as swapping texture A with B after
texture->native gets set in SDL_CreateTextures.

I've extended the gl error checks.
This is needed because on my system there are errors in the renderer that are
hard to find.
Also glError can return multiple errors. Even if SDL_SetError would only
contain the last one of course, the SDL log facilities are able to get the
output for each error.

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.

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
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.
I think this fixes the bug. I'm not sure why it would fail, and it may have something to do with the version of OpenGL that we initialize and use by default. Regardless, this should take care of the problem.

I tested the new build on my two ARM machines, and fixed a few bugs:
- if SDL_VIDEO_DRIVER_UIKIT, SDL_VIDEO_DRIVER_ANDROID or
SDL_VIDEO_DRIVER_PANDORA are specified, function pointers are grabbed from the
compile-linked library instead of through SDL_GL_GetProcAddress. (not sure if
this is the best way to go about it)
- removing "/usr/lib/" from all the library names (hey, with multiarch you
can't be too sure anymore)
- added glFinish to glesfuncs.h
- changed the eglGetProcAddress arg type to "const char *" as per the EGL spec
- filled in the stubs for X11_GLES_SetSwapInterval and X11_GLES_GetSwapInterval

This submission is aimed at making life easier for OpenGL ES capable devices
running a X11 stack (e.g. Maemo, Meego, TrimSlice, other ARM SoC boards not
running Android). SDL's Pandora support already has the neccesary GLES-to-X11
glue code, however it's all ghetto'd off in Makefile.pandora and not very
flexible.
The patch:
- adds an awesome --enable-video-opengles option to configure
- re-modifies the opengles and opengles2 SDL_renderers to use function pointers
- no idea why this was removed?
- for SDL_Renderers, links in libGLESv1_CM, libGLES_CM (for PowerVR fans) or
libGLESv2 at runtime
- links in libEGL.so at runtime - the old code made an assumption that
eglFunctions could be pulled from the active GLES library, PowerVR for one
doesn't let you do that with their libGLESv2
- allows you to pick which of GLES v1 or v2 to load via
SDL_GL_CONTEXT_MAJOR_VERSION
So far I've tested this on a Nokia N900 (OMAP 3430/SGX 530 running Maemo 5) and
a Toshiba AC100 (Tegra 2 running Ubuntu 10.10). I haven't tested it on... well,
everything that isn't those two, such as a Pandora, iOS or Android device. The
Pandora specific code should be kept intact (fingers crossed), and nothing
painfully drastic has been added to the SDL_renderers. The library loading
sequence in SDL_x11opengles has been updated to accomodate both NVIDIA's
propensity to let developers get away with murder and PowerVR's alternative of
punishing every missed step.
The test apps work okay with GLES or GLES2 as the renderer. For some reason
alpha blending doesn't seem to work on the Tegra 2; last week NVIDIA pushed out
a new set of X11 GLES drivers, so I'll try and investigate once I upgrade
those. Also, this patch adds things to configure.in, include/SDL_config.h.in
and test/configure.in. I didn't know what the policy was re. committing
generated spaghetti from autotools, so ./autogen.sh has to be run again. Sorry.
I think that's about everything, let me know if there's anything I've
overlooked.
