- `--help`: Displays help on commandline options.
- `--fuzz <max>`: The fuzziness. Used to add some deviation in ARGB data

(normally used on lossy codec).
- `--perceptive-fuzz`: Used to scale dynamically the fuzziness based on
the alpha channel value. This is useful on images with pre-multiplied and
small alphas. Qt can use different roundings based on optimizations resulting
