[vtkusers] VTK crashes when adding multiple lights

Hello Everyone,

I'm working on illuminating a scene and noticed that adding more than 6
lights cause issues; if they are not positional, then spurious colors start
appearing after adding 6 and vtk crashes after adding 19 lights.
It the lamps are positional, then it crashes when adding more than 6.

I'm not sure this is a bug, but the vtk light class does not indicate such
a limitation.
