        Both abiword and gnumeric do something like:

        Will this still work if we use
        gdk_window_begin_paint_rect (win, rect);
        cr = gdk_cairo_create (win); some drawing
        gdk_window_end_paint (win);

you're drawing on the window outside of an expose/draw event?

Yes, because using draw events presents serious performance issues.
