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.
Even if we're blitting between two different surfaces their pixels might still overlap, because of SDL_CreateRGBSurfaceFrom(), so always use SDL_BlitCopy() and check for overlap in that function.
When handling overlapping surfaces, don't assume that memcpy() iterates forward, instead use memmove() correctly, and provide a fallback implementation of SDL_memmove() that handles the different cases.
Fixed a bug with SDL_memset() not completely filling lengths that aren't a multiple of 4.
Optimized SDL_memcpy() a bit using the same technique as SDL_memset().
The trick is that if you're using configure and you don't want to have SDL_config.h and SDL_revision.h to show up as modified, you need to configure and build from a separate directory.
You also need to include SDL_revision.h directly if you want to use the SDL_REVISION constant, as a side effect of these changes.
--HG--
rename : include/SDL_config.h.default => include/SDL_config.h
The render viewport is automatically re-centered when the window changes size, so applications that don't care will not have to handle recalculating their rendering coordinates.
Fixed API for drawing and filling multiple rectangles - the parameter should be an array of rects, not an array of pointers to rects.
Fixed API for updating window rects for consistency with other APIs - the order is pointer to array followed by count in array.
Fixed creating render texture framebuffer.
Removed the need for palette watch, added surface format caching.
Added an SDL_DONTFREE flag so you can't free the window and 1.2 shadow surfaces.
There's a new event that's always sent when the window changes size, and that event is what the renderers listen for to determine if they need to rebind their context.

summary: improve header files compatibility with SDL 1.2 applications (namely QEMU)
The following patch fixes some of the bitrot for the Nintendo DS port.
The support is still basic at the moment, but it allows to run the "general"
test under the current head of tree (parent: 5269:11bd1585efb5 tip).
Most of the patch is mine, but I integrated a couple changes that John
Magnotti posted on Feb 1st.
attached is a working directfb driver diff which works with the current
changes. There are a number of changes around it as well, e.g.
configure.in.
The directfb renderdriver right now still depends on a some "includes"
from src/video/directfb. That's why it is not yet moved to the new
render folder.
