Need a noninvasive vtkActor::GetProperty()

Unfortunately if the vtkProperty objects are automatically created by vtkActor::GetProperty(), they contain uninitialized values (garbage values that are different each time I run the program), so they could have shading set to Flat or Gouraud randomly.

I don’t understand how this might be happening. If I look at vtkActor::GetProperty(), I see it invokes vtkActor::MakeActor() which simply invokes the vtkProperty constructor. In that constructor, the Shading member variable is indeed initialized.
