The GDK backend could be simplified a lot if we could pass a clipping region (which consists of a set of clipping rectangles) to DirectFB directly. On the other hand we'd have to provide software fallbacks for this feature and would have to care about the case when the number of rectangles in our region exceeds the maximum number of clipping rectangles the hardware supports. I doubt that the increase in code complexity (and thus library size) would be worth it.
