I was wondering about Histogram and Overlayframe and was just being overly
cautious by backing them out.  So unless someone mentions a problem with
them before Feb. 29, I will add those 2 back in.  Meanwhile, I will at
least see if I can reproduce the color3way issue and look at the code, but
do not expect I can solve it.

assure myself that they were working as documented and comparing them to
output from Gimp and SVG.  This was because IgorV made a note in his blog
that at least one of them was all wrong -- it was not, and that was because
of history and design differences.   I found the following necessary as a
reminder of how to get the expected results with PorterDuff.

Just now, in comparing the results with the alternative views in the
manual, the PorterDuff matches what I see. I will send Andrea the png file
I used as the base to be used with any other landscape png on the second
track - both of which better illustrate the results when offset as shown in
the manual.
