[vtkusers] Render order - Depth sorting volumes

[Karthik Krishnan]

Simon:

You don't need to use depth peeling. The bounds of your volumes don't
overlap. Just set the culler's sorting mode to back to front (default is
none) and everything should work out of the box... something like :

renderer->GetCullers()->GetLastItem()->SetSortingStyleToBackToFront();
renderer->AddVolume(vol1);
renderer->AddVolume(vol2);
