[vtkusers] Combining resliced images and polygons

Set cutter.GenerateCutScalarsOff()

and

Actor.GetProperty().SetDiffuseColor(color)
Actor.GetProperty().SetDiffuse(0.8) Actor.GetProperty().SetSpecular(0.3)
       Actor.GetProperty().SetSpecularPower(20)
      Actor.GetProperty().SetRepresentationToSurface()
