optimize SM_SDL_ErrorDiffusionDither like SM_SDL_OrderedDither; now
it's only about 50% slower
this also fixes banding after dithering gradients

optimize SM_SDL_ErrorDiffusionDither: takes about half as long now
(but it still takes 3x as long as SM_SDL_OrderedDither, and I still
see banding in both vertical and horizontal gradients ...)

worked on Error diffusion dithering algorithm, but it doesn't end up looking much better than OrderedDither

fix dithering when dest has alpha and source does not; also fix it
when dest has more alpha bits than the source (rare)

(started to write another resize filter and ended up doing this instead)
