the vtkInteractorStyleTrackballCamera has its own default picker that is
triggered when 'p' is pressed - this displays a red box around the
picked actor. </span></span></span></font></div>

vtkInteractorStyleRubberBandPick however, when used with the vtkAreaPicker,
operates on the selection rectangle (also when 'p' is
