probably fairly easy using a class level attr in the MouseEvent.
Another possibility would be to add support for figure_enter_event,
figure_leave_event, axes_enter_event, axes_leave_event.  The user code
would have to separately process the axes_leave_event but this might
be the cleanest solution.  I am happy to add support for these ...
