    Fix clipping of drawn pixbufs in the no-render case
    
    The fallback pixbuf rendering case ends up calling gdk_draw_image() on the
    destination drawable wrapper, which resets the previously set clip region.
    So, we need to manually get the impl and draw on that directly.
    
    This fixes bug 592752 where we don't clip pixbuf rendering on non-render
    Xservers.
