Guillaume Martres e55f60240a Implement variance-based adaptive quantization
This should be similar to what x264 does with --aq-mode 1.
It works well with clips like parkjoy and touhou
(http://x264.nl/developers/Dark_Shikari/LosslessTouhou.mkv).
At low bitrates, the segmentation signaling overhead may negate the
benefits of this feature.

(PGW) Default changed to feature OFF to allow provisional merge.
