[vtkusers] vtkImageViewer2 and current Mouse Position (MouseMove)

[Margarete Herbst]

I reply to myself:
now, I added the MouseMove-observer to the image viewer's render window
interactor instead of the interactor style
(m_ImageViewer->GetInteractorStyle()->GetInteractor()). MouseMove and user
interactions (zooming, panning ...) work both, now.
