Someone asked in IRC whether they should free the surface from SDL_GetWindowSurface. The doc comment is a bit vague so i checked the code and revised the comment.
Implemented thread priority as the 'nice' value on Linux. High priority threads require root permissions (you shouldn't give your game root permissions though!)
The bitmap ordering is defined such that the numbering refers to the pixel index from left to right, and the number position refers to the bit position in the byte.
SDL_BITMAPORDER_4321 is the fourth pixel at the high bit and the first pixel at the low bit (LSBFirst)
SDL_BITMAPORDER_1234 is the first pixel at the high bit and the fourth pixel at the low bit (MSBFirst)

For those interested, here's a snapshot of the current port. I did away with
most of the previous attempt which was based of the sprite engine, because the
support is limited to 128 64x64 sprites. Instead I'm using the gl engine.
The drawback is that either the frame buffer or the gl engine can be used
because there's not that much video memory on a DS.
With minimal changes to their code, it can now run the following tests: ,
testspriteminimal, testscale and testsprite2. The last 2 only run under the
emulator for some reason. The tests are not included in this patch for size
reason.
In 16 bits mode, the 16th bit indicated transparency/opacity. If 0, the color
is not displayed. So I had to patch a few core file to set that bit to 1. See
patch for src/video/SDL_RLEaccel.c and src/video/SDL_blit.h. Is that ok, or is
there a better way ?
The nds also doesn't support windowed mode, so I force the fullscreen in
src/video/SDL_video.c. Is that ok, or is there a better way ?
To get a smaller library, I also tried to not compile the software renderer
when the hardware renderer is compiled in, and define SDL_NO_COMPAT; however
the compilation eventually fails in SDL_surface.c because SDL_SRCCOLORKEY is
defined in SDL_compat.h. Is SDL_NO_COMPAT only for application and not SDL
itself ?

Adding patch that adds a simplified API for the haptic subsystem built ontop of
the "real one" for those who want simple rumble without jumping through hoops.
Adds 4 functions:
- extern DECLSPEC int SDLCALL SDL_HapticRumbleSupported(SDL_Haptic * haptic);
- extern DECLSPEC int SDLCALL SDL_HapticRumbleInit(SDL_Haptic * haptic);
- extern DECLSPEC int SDLCALL SDL_HapticRumblePlay(SDL_Haptic * haptic, float
strength, Uint32 length );
- extern DECLSPEC int SDLCALL SDL_HapticRumbleStop(SDL_Haptic * haptic);
Also provided is test/testrumble.c which does test this.
This has all been tested on linux and has worked, but due to being built ontop
of the other haptic API it should work on all OS the same.
