    avoid redundant idle if using FRAME_SYNC to throttle
    
    This updates the examples and test-journal which now use the _FRAME_SYNC
    events to throttle rendering so that they don't install a redundant idle
    handler to paint when they get a FRAME_SYNC event and instead they now
    directly paint when the event is received.
