Strange....  I'll look into this later.

We could, but it would require some redesign.  Tick is a class, and
the axis contains a list of ticks.  Thus it would take some top-level
redesign.

It's always that way :-) That is what the send button is for: self
enlightenment.

    Darren> OK. Would you add the signature to backend_bases?

Not yet.  I was just suggesting you use this internally.

    def draw_markers(self, gc, path, rgbFace, x, y, transform):

        self.push_gc(gc)

        while 1: 
          .... snip...

and later when it becomes part of the api, you'll already have done
the hard part.  You can also call this function from draw_ps.
Basically, all you need to do is rip the gc setting part of out of
draw_ps.
