I've confirmed that caching the previously computed data makes this
usable.  But I'm still not sure where to cache things.  Ideally, this
would be a "per-image" cache, so that we can have several animated
images at the same time.  But the way the animation is called, it kinda
creates a new image every time.

Hm.  Perhaps that's where to fix this?  Make the animation function
cache the data in the image structure somehow?

Anybody got other ideas?
