Notes:
1. SAD3 has the same value as either SAD1 or SAD2; whichever has the least number of
lines (set by SL1 and SL2).
2. Since the parameters corresponding to SL3 and SL4 are fixed by L/F, they do not have to
be set.
3. If, and only if, W/S = 1, the differences between SL1 and (L/F + 1) / 2, and between SL2
and (L/F + 1) / 2, are blanked.
