Removes useless lines
Resolves the rbzoom bug appearing when the ctrl key is pressed when the application loses focus
I added a new class vtkInriaInteractorStyleRubberBandZoom which inherits
from vtkInteractorStyleRubberBandZoom, this class will enable us to
reimplement some function to our advantages. Now the ctrl + right click
activates the rubber band zoom in all modes.
