function for polygons, regions and VNFs.
Fix bug with anchors for linear_sweep (due to centerpoint issues)
Fix intersection anchors for vnfs when anchor vector intersects
in a path instead of a single point.

5a4d9554df err message tweak in star() 
rearranged polygon_line_intersection to handle 2d and fixed
but where it didn't test polygon membership correctly.  Also
there was a bug with use of the bounded argument.
Added Ronaldo's triangulation.

60dbf8c73e Fix bug where polygon_normal and plane_from_polygon sometimes give a 
wrong-pointing normal.
Rename project_onto_plane to plane_closest_point for consistency with
line_closest_point.  (Also this distinguishes it better from
project_plane.
