[vtkusers] Multiple Surfaces at same height

[Gerrick Bivins]

I'm using it like this in Java:
>         partMapper = new vtkPolyDataMapper();
>         partMapper.SetInput(normals.GetOutput());
          partMapper.SetResolveCoincidentTopologyToPolygonOffset();



> 
>         partMapperwl = new vtkPolyDataMapper();
>         partMapperwl.SetInput(normals.GetOutput());
>         partMapperwl.SetLookupTable(lut);
          partMapperwl.SetResolveCoincidentTopologyToPolygonOffset();
