[vtkusers] InteractorStyle Subclassing

[David Cole]

It does sound reasonable.

I work on a project where we do this: subclass the trackballActor
interactor style and then instantiate and hold a camera interactor
style that we delegate to "when appropriate", and the when appropriate
is based on whether the trackballActor interaction prop is null or not
at mouse down time.

Totally works.

I'd point you to it, but it's not publicly available open source at
this point...

Good luck!
David C.
