e8ab6a825a VP8EstimateQuality(): roughty estimate webp bitstream quality factor 
This function returns a rough estimation of the quality factor used
for compressing the WebP bitstream.

Simple command line: 'webp_quality [-quiet] in.webp'
should print the estimated quality factor.

3f4042b52a WebPAnimEncoder: If 'minimize_size' and 'allow_mixed' on, try lossy + lossless. 
This improves compression by ~5% at default quality.

If only 'allow_mixed' is on (but 'minimize_size' isn't), we continue to
use a heuristic to try one of the two or both.

5b60db5c9d FastMBAnalyze() for quick i16/i4 decision 
The decision is based on the variance between DC values of each
sub-4x4 block. This heuristic is rather ok for predicting whether
the 2nd transform (intra-16) is going to help or not.
The decision threshold varies with quality (=quantization).

It's only used for -m 0 and -m 1, where no full RD-opt is performed.
It actually makes these modes quite faster, with RD curve much
closer to the -m 2 mode.
