hey, thank you so much. it's not only a very illustrative example, it's
exactly what we need. the C (contrast) value behaves very similar to the
saturation of [pix_contrast]. the only difference: -1 is greyscale, 0
seems to be normal colors and anything above seems to be saturation of
the colors. 

yo... we owe you a beer, as soon as you find your way to zurich, dude.
thanks again.
