I see.

This is different, isn't it?  FigureCanvas calls figure.draw(renderer)
only calls this with proper figures and never with other Artists.
So inheritance is not used here.

Ok!  This makes it look ok to me.
I am just in the process of understanding how the internals
of matplotlib work.

It seemed to work fine, but maybe I just didn't spot the
problems.  Now I can't really understand how the set_transform calls
in Figure._set_artist_props could possible have worked.
