It's not really that shocking.

Adjusting saturation doesn't make a lot of sense in RGB. It'd probably have to convert to YUV internally anyway.

It's too bad that AviSynth supports only YUY2 and YV12, though, which downsample the chroma.

Two words, plain and simple. Hardly what I would call a "description". Really just a "notification." And not even close to an "explanation".
Well, I meant in response to your questions about what the last version was that had it.

If you want a fuller explanation:

Adjusts colors in HSI space. Tweak works better except it doesn't have gamma. Since Tweak is technologically leaps and bounds ahead of HSI, they should be merged (just add gamma to tweak) or HSI should simply be dropped before someone gets dependant on it. HSI behavior is unpredictable at anything more than very minor corrections.
