That's weird; the importer should read actors, lights and cameras
separately. Well; I'm assuming that's what the protected methods
ImportActors(), ImportCameras() and ImportLights() do in vtkImporter...

And as these things are put into different collections, I would expect
you get the number of items in that collection only (although I'm not
sure what happens when there are multiple cameras, since there is no
such thig as a vtkCameraCollection).

What do you get when you call this?:

   int nlights = importer->GetRenderer()->GetLights()->GetNumberOfItems();
