If a SDL_Surface has a color key for transparency, then can that surface get blitted by the HW blitter? or: Does the blitter support that on a HW basis?
Following scenario: If the HW blitter could blit those easily (and fast) then creating dedicated sprite versions for different stripple alpha values. As we could benefit from the asynchronous nature of the HW blitter. If a color keyed blit is synchronous anyway, writing a blitting routine with dynamic stripple alpha would be the way to go. If there is a difference in blitting solid bitmaps and color keyed ones: How would that influence the answer of my question here?
