    Removing rounding from UV MV calculation · 2987fa1d
    John Koleszar authored
    Consider the previous behavior for the MV 1 3/8 (11/8 pel). In the
    existing code, the fractional part of the MV is considered separately,
    and rounded is applied, giving a result of 6/8. Rounding is not required
    in this case, as we're increasing the precision from a q3 to a q4, and
    the correct value 11/16 can be represented exactly.
    Slight gain observed (+.033 average on derf)
