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.
