[vtkusers] vtkLODActor don't works on Trakball interactor style

[Charl P. Botha]

Hello there Prabhu,

In 3.2, these calls are in the base vtkInteractorStyle, method StartState(),
StopState(), StartAnimate() and StopAnimate(), which in their turn are
called by StartRotate(), EndRotate(), etc. methods.
vtkInteractorStyleTrackball{Actor,Camera} does not make use of these
start-stop calls, so the UpdateRate calls never get done.

I've checked 4.0, and it seems to have the same problem.

Hope this helps,
Charl
