Actually, I don't care (tremendously) if I have to wait 'til after it's
drawn to get the info (I've already found other instances where, to do
what I've wanted, I've had to draw, then get/modify/set then redraw - as
you say, inelegant, but serviceable; it's not like the old days where
re-drawing meant waiting half a minute) so if that info is available
after the figure's been drawn, that's good enough for me (as long as
it's possible to set it as well as get it) for now. Is that what
legendPatch.get_window_extent().get_bounds() does? (I'll probably find
out using dir before you reply, but a reply would be appreciated anyway,
so the info will be in the archive).

I'm getting closer to the point where I feel like I might be capable of
doing this, but I'm not quite there yet. :-)

This is closer to my confidence level.
