Thanks for the comprehensive tests. I've had a minute to work on a
couple of these before I have to run out

I'm not too concerned about wx, and am somewhat inclined to pull it,
especially now that we have support for external backends so those who
need it can use it. I won't pull it for this cycle. Anyone who
loves wx, now is the time to step up andstart adding support for
missing features like images and mathtext.
But this example revealed a serious problem for wxagg -- the wx
backend save method was getting triggered. So wxagg couuld display an
image, but if we try to save it, it fails because backend_wx's
print_figure is getting called. I fixed this by reversing the order
of the inheritance in FigureCanvasWXAgg so that FigureCanvasAgg is
first. *please test*.

not concerned here about wx, but we need to make sure wxagg is working
here (confirmed)

added to the sf bug tracker, assigned to Michael. Added to
backend_driver (failing now)

fixed in svn to use the new callbacks API for scalar mappables. Added
to backend_driver
OK, that's all I have time for now. I'll take a look at the others
later. Thanks a lot
