------- Additional Comments from Hin-Chung Lam <hclam at google.com>
Thanks for Peter for the thorough review.

Major changes in the last patch:
* Fixed the problem of empty last frame. No more differences in the 60k images
corpus.
* Fixed two bugs uncovered by your review. Added a unit test to verify.
* Fixed the 3 bytes out of bound read.
