4 // An effect to convert between different color spaces.
5 // Can convert freely between sRGB/Rec. 709 and the two different Rec. 601
6 // color spaces (which thankfully have the same white point).

8 // We don't do any fancy gamut mapping or similar; colors that are out-of-gamut
9 // will simply stay out-of-gamut, and probably clip in the output stage.
