[vtkusers] how to disable deletion of reference counted objects?

[Bruce.Lamond at ed.ac.uk]

Hi,
I've written a vtkLight subclass and added instances of it to a renderer via a
new vtkImporter subclass. I'm trying to access the extra information in the
lights added to the renderer later in the program via the renderer, but I can
only get at the information held in the last light to be added to the renderer.
I suspect this is because the light objects are deleted after being added to the
renderer. Is there any way to override this deletion? I see that a
SetDeleteMethod() is commented out in the Render() method of subclasses of vtkLight.
cheers
