+// A simple desaturation/saturation effect. We use the Rec. 709
+// definition of luminance (in linear light, of course) and linearly
+// interpolate between that (saturation=0) and the original signal
+// (saturation=1). Extrapolating that curve further (ie., saturation > 1)
+// gives us increased saturation if so desired.
