Is cmfull() intended to be called on its own, or only through cmfullshift2 ?

EDIT: I've upped two frames here, intended so that we all have same test frames [EDIT: Added color frames].

Both already border cropped and GrayScaled. RGB24 BMP.

and test script for comparison

Delta frame shows difference between original script and supplied, if eg more red then mod is more red.

EDIT: We dont seem to be getting any blues at all. Cyan in Delta frame would indicate Lack Of Red rather than Too Much Blue.

EDIT: Added color BMP's to the 7z
