It works reliably with images as long as the transparent regions of the
image are 100% transparent.  Try it.

Routines for polygons should work reliably as well.

(Although Jim's routine seems to work only for intersecting edges, and not
when a smaller polygon falls *completely* within a larger polygon -- any
tweak available Jim?)
