[This is a note to self; [Bounty] tag is there because I'd be damn happy if someone were to solve the problem before I get to it]

This imposes a lot of churn per-scanline, especially when there's a lot of sprites. A better way would be to populate some kind of lookup table when calling setSpritePosition. I haven't decided the shape of this yet.
