I figured we would go to 1.0 when we run out of 0.88, 0.89, 0.90....

I think the API is pretty stable already, and suspect we won't be able
to guarantee much more stability after 1.0. Think about pygtk -- it
changed like a madman from 1.6 to 1.99 to 2.2 to 2.4... Sure, Numeric
was pretty stable after 10 years and 23 major releases, but then that
was broken with numarray and numpy. I'm not sure that API stability
above and beyond what we are already providing exists that much in the
wild, so 1.0 is probably more of a psychological landmark than
anything else. But maybe I'm just crazy.

I would like to fix the axis handling to be more flexible (eg, multiple
y axis lines per plot, detacable axis lines, etc) before 1.0.
