Okay. This is still not as good as a short Python or Tcl/Tk example that
other readers of this list can run, but it's better than nothing.
Does the same happen if you use a vtkVolume (i.e. no vtkLODProp3D)? For all
clarity, the volume that you add to the renderer FIRST gets occluded by the
volume that you add afterwards?
