Sorry, I mis-typed ... no copy cost with the addition sweep visitor.  I 
hit "copy costs" when converting some of my old code to arrangement_2, 
because my old proprietary buggy planar map had an in-place overlay 
operation rather than a make-a-new-one overlay operation.  But this has 
really been an issue of finding the right CGAL algorithms to utilize.

Okay.  If there is open-source infrastructure for my code, could you do 
a download-build-run cycle, or do you need the test case distilled even 
farther?  The situation is fairly involved, so I'm not sure how many 
steps it might take to build an isolated case.

cheers
Ben
