skal cbdd3e6e53 add a -dither dithering option to the decoder ... Even at high quality setting, the U/V quantizer step is limited to 4 which can lead to banding on gradient. This option allows to selectively apply some randomness to potentially flattened-out U/V blocks and attenuate the banding. This option is off by default in 'dwebp', but set to -dither 50 by default in 'vwebp'. Note: depending on the number of blocks selectively dithered, we can have up to a 10% slow-down in decoding speed it seems.
