//! Image › Adjustments beyond the per-pixel adjustment-layer kinds:
//!
//! * parameter parsing for Selective Color and Color Lookup (both also adjustment layers; their
//!   commands are generated with the other kinds in `commands.rs`),
//! * the destructive-only adjustments: Shadows/Highlights, Replace Color, Match Color and HDR
//!   Toning (maths in `photocraft_algo::tone`).
//!
//! Destructive adjustments convert the target (layer pixels, or a targeted alpha channel /
//! Quick Mask) to straight RGBA, so every colour model and bit depth is handled, and blend the
//! result through the selection like the other Image › Adjustments commands.
