    This commit extends the chessboard pattern prediction filter search.
    If the above and left blocks have the same prediction filter type,

    reference one.
    The overall chessboard pattern prediction filter type search reduces
    speed 3 runtime for hard clips. Experiments on park joy at 1080p
    and 15000 kbps show that the runtime goes from 723265 ms to 65832 ms,
    i.e., about 10% speed-up. Compression performance wise, it affects
    the coding quality by
