[vtkusers] 3d texture map volume rendering - culler

[Amy Squillacote]

Try using the culler that the renderer creates itself.  The code would look 
like this.

vtkFrustumCoverageCuller *culler = 
(vtkFrustumCoverageCuller*)(renderer->GetCullers()->GetItemAsObject(0));
culler->SetSortingStyleToBackToFront();

Then you won't need the AddCuller line.
