comparison include/SDL_pixels.h @ 1675:d33dcfc3fde7 SDL-1.3
Overlay functions are being replaced by YUV textures.
If the driver doesn't support YUV textures, they can be emulated by backing
the texture with an RGB texture and using the software conversion routines.
Note that it doesn't make sense to lock a portion of a YV12 texture, since
you'd need to return three pixel pointers and pitch values instead of the
one that's available through the API. I'm guessing that's one of the reasons
DirectX 9 doesn't support this format at all.
