VM-free color space enum for images stored in the display list.

Marked #[non_exhaustive]; cross-crate match expressions need a wildcard arm to remain forward-compatible.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Lab

CIE Lab* color space (PDF /Lab or ICCBased Lab alternate).

Sample byte layout: 3 components (L, a, b), 8-bit each. Decode scales bytes: L = byte/255 × 100; a = byte/255 × (range[1]-range[0]) + range[0]; b = byte/255 × (range[3]-range[2]) + range[2].
