First of all, I do not see my email in the vtk dev list, so I hope I did 
not just send it to you.

Neither of these, sorry.
The trackball style are vtkInteractorStyleTrackballCamera and 
vtkInteractorStyleTrackballActor. They are used and driven (as well as the 
joystick mode) by vtkInteractorStyleSwitch.

vtkInteractorStyleTrackball is in fact both 
vtkInteractorStyleTrackballCamera and vtkInteractorStyleTrackballActor, 
i.e. duplicated code (i.e. it was written before, then split into the two 
other one, if I remember correctly), etc.
