<DIV><FONT face="Bookman Old Style">The vtkInteractorStyleTrackballActor uses
Cell picker to pick the actor. It's very slow. I want to change the cell picker
to propPicker. I cannot find the member method to change the cell picker to prop
picker in vtkInteractorStyleTrackballActor. Is the only method to inherit from
vtkInteractorStyleTrackballActor and change the picker in this child
class?</FONT></DIV>
