Matt,
Currently, (if I understand the backends and the event handling correctly),
mpl makes the assumption that a window resize event directly means a figure
resize event. Maybe these two concepts should be decoupled to allow for
interception and handling? I don't know how much work the mpl backends have
to do to handle the various possibilities of when to scale the figures and
when to use scrollbars. Certainly would be quite messier than the current
assumption.
Unless I am being completely unaware of current ways to implement what you
want, I would suggest filing a feature request. In the meantime, editing
the tk backend might be your best bet.
Cheers,
Ben Root
