    While investigating the effect of DC values on SAD and SSE in motion
    estimation, a side finding indicates the two table of constants need
    be adjusted. The adjustment was done by multiplying old constants by
    90% with rounding. Also absorb the 1/2 scaling constant into the two
    tables. Refer to change Ifa285c3e for background of the 1/2 factor.
    Cif set test showed a very small gain on all metric.
