Thanks Jean-Pierre,

 The newer code is based mostly on the old code. When I was working on
the idf2vrml tool I decided to clean up the code and try to fix a few
bugs; my plan was to replace the old code when I have finished the
idf tool and made improvements to the code. I'll continue to work on
removing the remaining artifacts so we have prettier results.
