Details:

I would like to have the possibility to pass escape codes unhandled through
screen to the terminal.

for tmux the escape characters in the original escape codes have to be
doubled.
'\033Ptmux;' is prepended to the string and '\033\\' (ESC \) is appended.

This would allow me to let the terminal handle sixel graphics but I think
there are many more use cases for it.

regular sixel code:

printf
'\033Pq#0;2;0;0;0#1;2;100;100;0#2;2;0;100;0#1~~@@vv@@~~@@address@hidden'


sixel code wrapped for tmux - tmux will pass it through to the terminal:

printf
'\033Ptmux;\033\033Pq#0;2;0;0;0#1;2;100;100;0#2;2;0;100;0#1~~@@vv@@~~@@address@hidden'
printf
'\033Pq#0;2;0;0;0#1;2;100;100;0#2;2;0;100;0#1~~@@vv@@~~@@address@hidden'
| sed 's/\o033/&&/g;s/^/\o033Ptmux;/;s/$/\o033\\/'
