Title: Utilize more of the available field of view for flow computation

This change spreads the patterns chosen for SAD computation more evenly over the available 64x64 pixel image instead of overlapping and bunching them up in a smaller area. This should give the system a better chance at finding good flow candidates in more difficult situations.

This code has been tested and found to work properly.
