[vtkusers] Window events on Mac OS X

[Peter Eastman]

As an experiment, I tried calling RunApplicationEventLoop() (which I  
can't really do in practice, since it freezes the rest of the program,  
but this was just an experiment).  The result is the same: I can move  
and rotate the view shown in the VTK window, but I still can't move or  
resize the window itself.  So this problem doesn't seem to be anything  
to do with how I'm handling events.  It appears that VTK simply isn't  
handling certain events properly.  Any idea what's going on?
