[CM] a rose by any other name...

I'm wondering if I should change all the "scaler" arguments to something 
else.
I used "scaler" decades ago because I didn't like the spelling "scalar". 
  According to the OED, "scalar" goes back to the 17th century, and 
derives
from "scala", a ladder, ultimately from Latin.  "scaler" is also old, 
and
refers to one who scales a mountain or a fish.  Well, I still
like "scaler" better!  "gain" looks like an escapee from the EE lab.
"volume" is too specific.  Maybe "scl" or "*"?
