[vtkusers] vtkPOVExporter problem - multiple face_indices

[Flanery Jr, Raymond E.]

For some reason my application is creating 2 sets of face_indices for each mesh object, which POVRAY does not like. I have reduced this to a fairly simple case. If you run test1.py it generates incorrect povray file, test2.py generates correct povray file. The difference is that test1.py extrudes the polygon and test2.py does not.

I have attached the files. Is there a bug in vtkPOVExporter?
