    Use new clutter_stage_set_paint_callback() function for after-paint notification
    
    Commit 4f2bb583bf8c changed things so that the compositor used
    clutter_threads_add_repaint_func_full (CLUTTER_REPAINT_FLAGS_POST_PAINT
    to get after-paint notification and send _NET_WM_FRAME_DRAWN, but this
    doesn't actually work, since Clutter will already have blocked for
    VBlank before calling post-paint functions.
    
    The result is that frame synced toolkits like GTK 3.8 will normally
    only be able to draw every other frame.
    
    Since ::paint doesn't work either, a new function
    clutter_stage_set_paint_callback() has been added to Clutter
    (and will be included in the 1.14 branch)
