Summary:                    QVTKWidget and QVTKWidget behave differently;
resizing breaks interactor for QVTKWidget2
Description: 
The attached small python test case shows some problems with QVTKWidget and
QVTKWidget2. I'm using the latest VTK built from git HEAD.

1.) QVTKWidget and QVTKWidget2 behave differently. When the mouse moves over the
plane, it gets highlighted green for QVTKWidget but no highlighting happens for
QVTKWidget2. Is this a bug or a feature?

To reproduce, run
python test-qvtkwidget.py 1   // to use QVTKWidget
python test-qvtkwidget.py 2   // to use QVTKWidget2

2.) Try resizing the window when using QVTKWidget2 (see above). Now the plane
cannot be dragged anymore. I have tracked this problem down, one can work around
this by resizing the interactor in a resizeEvent like this:

def resizeEvent(self, event):
        #ordering is important here
        http://public.kitware.com/Bug/view.php?id=1.) Let the QVTKWidget2 resize
itself
        QVTKWidget2.resizeEvent(self,event)
        
        w,h = self.width(), self.height()
        http://public.kitware.com/Bug/view.php?id=2.) Make sure the interactor
is assigned a correct new size
        self.renderWindow.GetInteractor().SetSize(w,h)
