+// An effect to convert between different color spaces.
+// Can convert freely between sRGB/Rec. 709 and the two different Rec. 601
+// color spaces (which thankfully have the same white point).
+//
+// We don't do any fancy gamut mapping or similar; colors that are out-of-gamut
+// will simply stay out-of-gamut, and probably clip in the output stage.
