[vtkusers] Lighting not consistent between release/debug builds

[Alex Malyushytskyy]

Usually if something is working in debug and do not work in release
the problem is in the initialization.
Have you tried small self-sufficient example?
If you could modify one of the VTK examples to demonstrate the problem
you could get
help from the developers or at least file the bug.
