[vtkusers] 3D model and 2d Image overlay - depth issues, flickering

[Miro Drahos]

Try to use the following:
   vtkMapper::SetResolveCoincidentTopologyToPolygonOffset();
vtkMapper::SetResolveCoincidentTopologyPolygonOffsetParameters(0.1, 1);

Just call these in the ctor of your viewer, they are static functions 
and will set some global variables.
If your issues are really coincidency, this should help. You may need to 
fiddle with the parameters a little bit.
Cheers,
Miro
