This is an implementation of Ken Perlin's gain function.
It boosts micro-contrast (acutance, in photographic terms) without clipping.
When set to 0.5, it has no effect. When >0.5, gain is boosted; when <.5, gain is muted. Only luminance is affected; not hue nor saturation. Superwhites remain untouched.
