    When active map is specified and the current frame is not a key frame,
    golden frame nor a altref frame then copy only those active regions.
    
    This significantly reduces encoding time by as much as 19% on the test
    system where realtime encoding is used. This is particularly useful
    when the frame size is large (e.g. 2560x1600) and there's only a few
    action macroblocks.
