It would have to duplicate everything that's drawn to the screen on a memory
bitmap (not all drivers preserve video bitmaps). Not only that, but since
acceleration is going to be a main focus, Allegro would have to end up doing
things like bilinear interpolation, alpha blending, anti-aliasing, etc, in
software. I don't think the speed impact would be worth it.
