Simply ignore the event handler for Windowed mode in fullscreen.

With proposed patch by vernier.

You can also do this through the native API:
	UIWindow *window = [[UIApplication sharedApplication] keyWindow];

Also needed to name the union for events and window info.

--HG--
rename : .hgeol => .DISABLED-hgeol

Don't forget to add "eol =" to the "[extensions]" section of your .hgrc!

i was reading SDL_renderer_gles and i noticed that every time we there
is some gl call the gl state is modified with a couple of
glEnableClientState()/glDisableClientState.
While this is completely fine for desktops systems, this is a major
performace kill on mobile devices, right where opengles is
implemented.
Normal practice in this case is to update the glstate once, keep it
always the same and disable/enable other states only in very special
occasions.

On the web there's plenty of documentation (on the top of my head
http://developer.apple.com/iphone/library/documentation/3DDrawing/Conceptual/OpenGLES_ProgrammingGuide/Performance/Performance.html#//apple_ref/doc/uid/TP40008793-CH105-SW5
) and i personally tried this.
I modified my code and got a 10 fps boost, then modified SDL_render_gles and
shifted from 40 fps to 50 fps alone -- considering that i started from ~30fps i
got an 80% performance increase with this technique.

I have attached a dif of my changes, hope that it will be included in
mainstream.

GLES_UpdateTexture() ignores pitch value, because of that some textures created
with SDL_CreateTextureFromSurface() are drawn incorrectly, especially if image
width is not multiplier of 2.

fix the double free error

in SDL_uikitview the variable 'textfield' is initialialized and set to
autorelease.
however in the dealloc method a second [release] is sent.
If the textfield has not been set to nil before (with a viewDidUnload for
example) this can lead to awful hard-to-find crashes when the SDL code
terminates.

the error message is
-[textfield release] message sent to deallocated instance 0x4e5fa90

the fix is simple, just release the object as soon as it is added to the
subview, see attached patch

SDL doesn't depend on GLU, and overwhelming feedback from the mailing list is that people don't want it included in SDL_opengl.h

The are no event handlers for the middle mouse button, right mouse buttons, and
mouse wheel in the latest HG revision 4636. It has been like this for 3 months.
I made a patch for this, though I'm not sure if the Xbutton or mouse wheel code
is "correct" by your standards.

in SDL 1.3 (revision 5508 from SVN), the method used to calculate the
bits per pixel from a “int format” differ between “SDL_ListModes” (which
always uses the “SDL_BITSPERPIXEL” macro) and “SDL_PixelFormatEnumTo-
Masks” (which uses either “SDL_BITSPERPIXEL” or “SDL_BYTESPERPIXEL * 8”,
depending on the value of “SDL_BYTESPERPIXEL”).

Because the values are later compared in “SDL_ListModes” this may lead
to some valid video modes not being returned. In my case the only mode
returned by “SDL_GetNumDisplayModes” was dismissed and NULL was
returned. (This led to the calling application sticking its head in the
sand.)

The attached patch copies the method used within “SDL_PixelFormatEnumTo-
Masks” to “SDL_ListModes”. This solved the problem for me though I don't
fully understand the method used by “SDL_PixelFormatEnumToMasks”.

I *think* the patch below works correctly: sdl-config gets the -march
flag and SDL builds fine. Perhaps there's a better way to get the
-march flag into both CFLAGS and SDL_FLAGS w/o dragging along more
cruft, but adding it to BASE_CFLAGS seemed the best bet to my eyes.

I did some digging, and I think I've found a better solution. By
including some additional .m4 macros in the acinclude directory
(http://www.gnu.org/software/autoconf-archive/ax_check_compiler_flags.html,
http://www.gnu.org/software/autoconf-archive/ax_gcc_archflag.html and
http://www.gnu.org/software/autoconf-archive/ax_gcc_x86_cpuid.html)
then using the patch below (same as previous patch + one line change
to configure.in), SDL will build correctly out of the box.

The arch can then be overridden by --with-gcc-arch=<arch> (most will
probably want to build with i686 there for general distribution) or
--without-gcc-arch, to disable setting the arch all together.

On my Atom netbook, I get -march=PentiumPro by default, which works
great, as does --with-gcc-arch=i686.

Fixed building SDL test programs

That's actually okay, since gcc has the builtin atomic intrinsics. :)
