I'm just about to commit the current winding rule code, which should
work for most situations. I'll post a glut demo of the contours used in
the paper describing the algorithm for reference. Of course, it doesn't
handle self-intersecting contours correctly if the winding rule is
anything other than GLU_TESS_WINDING_POSITIVE - it gets into a real
mess, leaving the output contours dangling etc. I'm working on a fix to
this now.
The book/tess demo works well. demos/tessdemo works correctly depending
on the contours, but I haven't looked into this much. Again, when I fix
the self-intersecting contour problems I'll check this out. Contours
inside other contours that should be output (ie. book/tesswind) I know
how to do, just haven't coded it up yet.
I'll post again when the commit is done.
