Comment(by wcauchois):
Great work, Jason! There's still alot of work to do to make the excluded
regions smooth, but we can address that in another patch. I can definitely
work on this.
About _clean_point_list(): We don't _have_ to deallocate unused vertices.
I took a look at some parametric plots, and in most cases the number of
vertices deleted in _clean_point_list() was under 100. The overhead for a
list mapping vertex indices to their (u, v) coordinates would be much
greater than the memory saved by _clean_point_list(). Does that sound
reasonable to you? Of course, there may be other reasons for maintaining
such a list or ensuring that all the vertices in the IFS are used...
