Hi -- in CGAL parlance "general polygon" means a contour whose
segments may be composed of straight lines, bezier curves or circular
arcs. If you take a longer look at the code in the page I linked to,
this will be clear. The mathematical parlance in the documentation is
a bit heacy though, so one needs to learn to read through that...
And re looking into the FT code, I guess I'll try that. Thanks.
