That would explain the dithering on the buttons in Filippos' "after" image
from QFG I.
Couldn't we find a way to un-dither after all? We know the palette that's
desired for the image, and we know how it dithers, so all that remains is
scanning the bitmaps for the (up to) 16 patterns and replacing them with the
proper palette colors. If that's too expensive, we can maybe add in hints
