a WebP encoder
converts PNG & JPEG to WebP This is an experimental early version, with lot of room of later optimizations in both speed and quality. Compile with the usual `./configure && make` Command line example is examples/cwebp Usage: cwebp [options] -q quality input.png -o output.webp where 'quality' is between 0 (poor) to 100 (very good). Typical value is around 80. More encoding options with 'cwebp -longhelp' Change-Id: I577a94f6f622a0c44bdfa9daf1086ace89d45539
