Hello CGAL,

I have re-implemented the functionality of OGL_helper.h by rewriting
the whole thing. Would the Max-Planck-Institute consider the
re-implementation to still be covered by their copyright, or is it
under my copyright?

My code uses the 'visitor' pattern of Nef polyhedron3 as described in
the CGAL manual, and feeds the results to GLUtess. The code is not the
same as OGL_helper.h, but it does bear a resemblance; there are only
so many ways to iterate through a facet cycle after all (I use next()
on a shalfedge_const_handle).

The reason for re-implementation instead of subclassing is to get more
control over the colors and the GLUtess code, and to make the OpenSCAD
project fully GPL.

Thank you
