[vtkusers] Using GetResolveCoincidentTopologyPolygonOffsetParameters etc

[Andrew Cunningham]

 Hi,
I am drawing a Finite Element mesh object where one wishes to display the wireframe mesh 'on top of ' the shaded mesh. Typically one does this in OpenGL by drawing the mesh twice - once filled and once as wireframe, using glPolygonOffset to make sure the mesh is visible.
VTK has the  functionality with the various Set/GetCoincidentTopologyxxx calls. But no examples and nothing on the mailing list as far as I can tell. Anyone have a code snippet? Or do I need another lesson in searching...

Cheers,
Andrew
