Part of the problem is the horrible and misleading sizes arg in PolyCollections, probably a hangover (yes, a headache) from supporting a Matlab-compatible argument in scatter. I can try to straighten this out and clarify the situation after the release, not before. I will add an alternative kwarg to scatter at the same time, and hope the old usage gradually dies out.
