Struct GlassFaceTone 

pub struct GlassFaceTone {
    pub black: f32,
    pub white: f32,
    pub saturation: f32,
    pub max_luminance: f32,
}

A fixed luminance transfer with an independent chroma gain. Luminance y becomes black + (white - black) * y - (1 - max_luminance) * y²; chroma is scaled by saturation and the combined RGB is clamped to zero–one.

Fields

black: f32

Black input’s output, from zero to one.

white: f32

White endpoint before quadratic highlight compression; greater than black.

saturation: f32

Chroma gain independent of the luminance transfer; finite and nonnegative.

max_luminance: f32

Highlight compression endpoint, from zero to one. One disables compression.
