[Cin] Histogram Plugin add on feature

[Phyllis Smith]

Yes, Yes, I can.  See the attached png file.  Note that the project was
created from a June 20, 2020 build (see the bottom section) and the project
was loaded on a build of September 18.  The color picker in the Compositor
shows the exact same value and the image colors look equivalent.  Of note
though is that the "Linear to Log Slider" will look different until you
slide it all the way to LOG which is what it was in the original
Histogram.  Adding the Linear and the percentages for sliding provides the
capability to see a more versatile histogram.  GG says something about the
lower colors are washed out of the histogram or the higher colors are too
prevalent when using LOG (this is probably quoted wrong) -- that is why it
is set to the default of 50% until you change it.  Note, that for
illustrative purposes I have the slider set to LINEAR.
