Looks like we have an inconsistency here with how we process our None's.
For most artists, properties defined as None in the constructor are then
given defaults from the rcparams. I would guess that text objects are
doing if on draw(), instead. At first glacé, I would guess that would be a
bug, but I would welcome other comments on this.
