Here's another idea: provide a "sprite+picture" structure, and have all the operations take in and return it. One could use it directly as a world in big-bang animations, for cases that only involve one sprite. Problems that require more than one sprite would use a world type that has a picture and a LIST of sprites, but they would pass into the operations only the picture and the relevant sprite, putting both back where they belong after the operation returns.
