[vtkusers] TrackBallActor and camera movement

[Totte Karlsson]

Hi,
I have a question on how to move the camera while being in 
TrackBallActor mode.

Particularly, I would like the camera to be moved, while in 
TrackBallActorMode, as if being in TrackBallCamera mode, if and only if 
the user clicks the mouse without selecting an actor.

Would there be an easy way to achieve that?
Would it be possible to derive from the interactor styles and then 
switch between them in corresponding event functions?
