[vtkusers] Overlaping view props in a rendered

[Sarah Macumber]

Here is a quick question I couldn't answer by googling ...
 
Is there any way to change the draw order of props / actors in a renderer.  Something like vtkProperty2D's  SetDisplayLocationToBackground() but more generic for those things that only have a vtkProperty?  The only thing I can find to do is place my objects in the scene in the correct order but that doesn't always work for me and I want the ability to change their draw order / z buffer later.
 
Cheers,
Sarah
