As far as I understand the dialog doesn't show absolute values for
Saturation and Lightness but relative ones. Perhaps the Saturation
slider should also go from -100 to +100 then.

First of all someone should take a look at the code and find out what it
really does. I very much doubt that anyone here can tell you this
without looking at the code. So why don't you just have a look and tell
us what you found?
