36aa087b6d get_disto: new option to compute SSIM map and convert to gray 
using -ssim -o will trigger SSIM map calculation instead of add-diff map.

-gray converts the error map to intensity instead of having each channels' error separated.

0de48e187d get_disto: add a '-o file' option to save a diff map 
also: -scale option is useful for using the maximum range.

57a5e3b6a5 webp_quality should return '0' in case of success. 
-> clarify the return value in case of error

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.

ad497fbce3 move src/extras to the top-level 
reserve src/ for the code of the main libraries: libwebp, libwebpdemux
and libwebpmux

+ demote this library to internal only; i.e., don't install the header +
lib with make install
