[Cin] oops apparently 'subtract' mode is broken!

[Andrew Randrianasulu]

so I am officially confused!

according to this
https://emptyeasel.com/2008/11/14/layer-modes-part-three-difference-addition-subtraction-darken-lighten/

color inversion in subtract mode IS normal thing.

yet in original Cin something else happens ....


may be Phyllis can replace our original red-green square  images with
full-color gradients + photo, so effect will be more natural? Or add this
into new appendix .....
