◆ _compute_reference_saturation()

static float _compute_reference_saturation ( const float  white,

The graph background should stay inside the preview gamut across the whole hue circle, so we binary-search the highest dt UCS saturation that keeps every sampled hue inside sRGB.

The GUI gradients are hue/chroma visual guides, not photometric previews. Keep in-gamut display colors untouched and only compress actual out-of-range linear RGB back into the unit cube before applying the display TRC. This keeps color equalizer and color primaries on the exact same display-rendering path.

GUI state and history entries are expected to normalize the editable hue nodes before they reach the shared sampler. Keep the interpolation backend away from empty or degenerate anchor sets anyway so it never throws from the underlying C++ spline code while a module is still repairing its params.

Sparse anchors let modules author their own control geometry while reusing the same RGB cylindrical local field as the original color rings. We therefore loop only over the caller-provided anchors instead of synthesizing fake ring samples that would bias the normalization.
