It seems the problem was in vtkGenericRenderWindowInteractor.h. Could one
of the developers please apply the attached diff?
The vtkTypeRevisionMacro call has vtkObject as the superclass instead of
vtkRenderWindowInteractor, which is why the Python code refuses to accept it
as parameter to vtk3DWidget::SetInteractor()
