Yes, that should work. Make sure to test it, though, as begin_paint_rect / begin_paint_region currently clears the specified rect/region to the background set on the GdkWindow. If passing a more exact region is too much of an annoyance, I should be able to also change this without breaking too much so that the clear to background only happens on expose events.
It's difficult to balance the requirements of everybody.
