This makes the Go code match the libwebp C code's output on blue-purple-pink-large.*-filter.lossy.webp Also make the various WEBP benchmarks all decode a similar image, the image at http://blog.golang.org/gophercon/image01.jpg, to make it more meaningful to e.g. compare the simple filter's numbers with the normal filter's numbers. Also fix a "go vet" warning in webp/decode.go.
