Hmm, that's an interesting way of doing sprites that I've never thought
about.  If your sprites somehow were made of repeating tiles, you could make
a special kind of tilemap to render the sprites.  Rendering a masked sprite
for a tilemap requires ANDing the sprite with the screen/background, ORing
that with the inverted (complemented) mask and loading that to the screen.
