That's possible, but there is already a quick and well-documented way to do it 
at the MPL level.  Situations like that, where there's already a 
backend-portable way to do things, are what WxMpl tries to cater.

I should have been more specific and said "plot-level user interaction code, 
like zooming".  For example, adding support for subplots means you need to add 
support for picking out which Axes object the user has drawn the selection 
over and rejecting the selection if it overlaps multiple Axes.
