then use a variant of queue_draw() that just queues up a redraw of a
specified rectangle or region (a set of rectangles).

alternatively, draw outside the expose event handler into an off-screen
drawable (e.g. a pixbuf), and in the expose handler, copy from the
relevant part of the pixbuf into the window.
