I am confused by the operation of the channel mixer.
If I open the mixer and look at the Red channel the 'red' value is nominally 
set at 1 ... if I now move the red slider to a lower level I would expect that 
the red values are diminished over the entire range but what appears to occur 
is that red values are minimized from the high end of the scale leaving the 
low end untouched. If I push the red value down to .500 then the entire red 
section of the histogram is bunched in exactly 1/2 of the scale.

I am not sure at all what the intention is with this module when used with 
values < 1.
