[vtkusers] Add multiple vtkVolume in vtkAssembly

[Aashish Chaudhary]

Hi Vincent,

Thanks for the feedback. If they are not overlapping in physical space then
you can do something like this (basically turn on the SortingStyle to
BackToFront)

 ren1->GetCullers()->InitTraversal();
  vtkCuller *culler=ren1->GetCullers()->GetNextItem();

  vtkFrustumCoverageCuller
*fc=vtkFrustumCoverageCuller::SafeDownCast(culler);
  if(fc!=0)
    {
    fc->SetSortingStyleToBackToFront();
    }
  else
    {
    cout<<"culler is not a vtkFrustumCoverageCuller"<<endl;
    }
