I meant if tmux doesn't support the kitty escape sequences we assume
should work.  And if it doesn't, we need a way to detect that the
terminal is displaying on tmux.  Does anyone know how to do that?

Because, according to my reading of the code I show above, we assume
that every terminal supports wave: if Smulx is not present, we assume
the kitty escape sequence will work.
