// Note: Movit's internal processing formats do not have enough
// accuracy to support 12-bit input, so if you want to use Rec. 2020,
// you should probably stick to 10-bit, or accept somewhat reduced
// accuracy for 12-bit. Input depths above 8 bits are also generally
// less tested.
//
// We also only support “conventional non-constant luminance” for Rec. 2020,
// where Y' is derived from R'G'B' instead of RGB, since this is the same
// system as used in Rec. 601 and 709.
