-Subject: [PATCH] application-sync: support Synchronized-Updates
-
-See https://gitlab.com/gnachman/iterm2/-/wikis/synchronized-updates-spec
-
-In a nutshell: allow an application to suspend drawing until it has
-completed some output - so that the terminal will not flicker/tear by
-rendering partial content. If the end-of-suspension sequence doesn't
-arrive, the terminal bails out after a timeout (default: 200 ms).
-
-The feature is supported and pioneered by iTerm2. There are probably
-very few other terminals or applications which support this feature
-currently.
-
-One notable application which does support it is tmux (master as of
-2020-04-18) - where cursor flicker is completely avoided when a pane
-has new content. E.g. run in one pane: `while :; do cat x.c; done'
-while the cursor is at another pane.
-
-The terminfo string `Sync' added to `st.info' is also a tmux extension
-which tmux detects automatically when `st.info` is installed.
-
-Notes:
-
-- Draw-suspension begins on BSU sequence (Begin-Synchronized-Update),
-  and ends on ESU sequence (End-Synchronized-Update).
-
-- BSU, ESU are "\033P=1s\033\\", "\033P=2s\033\\" respectively (DCS).
-
-- SU doesn't support nesting - BSU begins or extends, ESU always ends.
-
-- ESU without BSU is ignored.
-
-- BSU after BSU extends (resets the timeout), so an application could
-  send BSU in a loop and keep drawing suspended - exactly like it can
-  not-draw anything in a loop. But as soon as it exits/aborted then
-  drawing is resumed according to the timeout even without ESU.
-
-- This implementation focuses on ESU and doesn't really care about BSU
-  in the sense that it tries hard to draw exactly once ESU arrives (if
-  it's not too soon after the last draw - according to minlatency),
-  and doesn't try to draw the content just up-to BSU. These two sides
-  complement eachother - not-drawing on BSU increases the chance that
-  ESU is not too soon after the last draw. This approach was chosen
-  because the application's main focus is that ESU indicates to the
-  terminal that the content is now ready - and that's when we try to
-  draw.
