If the max height is just 16, then this should be fine. I assumed that h
could have a much higher value (>1024), but if that is not the case,
then this is a useful optimization.
At least according to the me_cmp.h header, which says:
/* Motion estimation:
* h is limited to { width / 2, width, 2 * width },
* but never larger than 16 and never smaller than 2.
* Although currently h < 4 is not used as functions with
* width < 8 are neither used nor implemented. */
So with that in mind, I think this should be safe to do.
