What is the best way to capture a change in the NSView size?

The semantics are simple: immediately after the view size has changed
(i.e. whatever rectangular region corresponds to the vtkRenderWindow),
a ConfigureEvent is invoked.  At the time when ConfigureEvent is invoked,
the view must have already achieved its new size.
