the upside-down font has its own difficulties as well.

specifically, it'd have to be right-justified,
with the string reversed from last to first.

and if it ran more than one line,
the line-breaks wouldn't be correct
i.e., the shortest leftover line would occur, as it always does,
at the end of the string, when you'd want it at the beginning.
