I have a subclass of QWidget that receives the Qt events and converts them
to my own events (which are similar to Qt events but also carry useful VTK
information). Those events are dispatched to my interaction bindings.
I've always done interaction in VTK this way. Neither the
vtkRenderWindowInteractor or QVTKWidget play any role.
