While working on this, I realized that we are always just adjusting the array
start/stop indices after all.  So I think we could simplify the optimizer code
some more -- I'll tackle that in a separate CL.

I don't understand why "Edge" is part of this name/test.

Someone (Federico or maybe myself) was referring to the optimization this way
(as in color stop domain edges), and it stuck.

Renamed to avoid confusion.
