This almost works, the biggest problem is that Core doesn't have a
repaint proc, and even if it did, a per-class repaint proc isn't what
you want for a window widget.

You want to make a simple subclass of core that has a repaint proc in
the instance, and a class repaint method that calls the instance repaint proc.

Alternatively do what Ralph suggested, but register an expose event
handler explicitly.
