Maybe (assuming I didn't miss anything in my description).
But how would you know that a library is not going to be used on a
tty?
It requires frames.
Also, is the call to defined-colors really that expensive? I just
tried it, and the response was immediate.
I call it quite often (although I do use a `let' to avoid multiple calls in
the same function). Rather, I call it in user commands that are on
repeatable keys, so they are often executed in succession, with the same
call to `defined-colors', producing the same list of colors.
