That's obvious

But why not simply have three sliders, one for each curve, giving the 
relative weight of each curve, just like the channel mixer in 
Photoshop? (would be nice though if the weights automically be 
balanced to 100%, a feature I miss in PS). The result would be just 
the weighted average of the three curves. Just like the current 
slider is the weighted average between two curves. The mathematics of 
this 3 curve averaging is trivial. What should this 
color engine do more than that? Do I miss something?
