I guess I did not make this very clear in my previous png or demo.  The
correction in past projects will stay exactly the same.  The only potential
difference you will see is in the histogram graph itself -- not the image.
For example, see the attached jpg file where the Slider is at Log, then
50%, then Linear.  You see to the right in the orange/red Compositor sample
that the color correction is exactly the same.
