[vtkusers] Removing internal cells !

[Sebastien Auclair]

Yes i'am using vtkLinearExtrusionFilter.
The polygons are complex and often non-convex so before being extruded, they
are passed through vtkGLUTesselatorTriangleFilter.

When displayed with transparency, we can see the internal facets !

Thanks !
