[vtkusers] RenderWindow question...

> How do you delete this window?

The user deletes it, by clicking on the window decoration close button.  The 
only way (that I know) to catch this is to have the window manager send you 
an event (i.e. WM_DESTROY_WINDOW).  If VTK catches this event, then that's 
great.... however, on my inspection of the code i can't find where this 
callback is setup.  Also, I'm not using XOpenGLRenderWindow directly, but I 
think that's where the code and the problem should be.
