Guys,
I helped Eric out with this offline, and obviously set_array is for the
colors, but the only solution we could come up with was to directly
reset the PolyCollection._offsets member. This seems a little hacky.
Is there any reason that there is not an set_offsets() (or something
like it)? Any reason why I shouldn't code up a patch?
