Does the quad-tree approach seem reasonable to people or is there something else we should do? It obviously uses more memory, but it's roughly O(n) in the number of RenderLayers, which already are giant memory hogs. Only tricky bit I think is making sure we keep it updated as layers move around.

An alternative approach would be keeping track of which layers are currently visible. This sounds less promising and more complicated to me though. Also, this approach would also benefit from the quad-tree thing.
