I think we want to add begin/end_frame_update hooks, and we want them
to send the escape sequences that are determined by some state
variable which tells us which of the 2 protocols to use.  We then need
a function to allow changing that state variable, perhaps by an
explicit user command.

Bonus points for making the state variable be terminal-specific, so
that the same Emacs session could have TTY frames on several different
types of terminal, and use the correct protocol for each one of them.

I hope I explained this well enough; if not, feel free to ask specific
questions.

No, that's too dangerous, and not really needed.  It's not like there
are many different protocols for synchronized update.

Thanks.
