3485e1c089 Tidy up server_client_check_redraw. Get rid of the bitmask tracking 
panes which want redraw for deferred clients - if they are deferred then
they can just have a full redraw instead. Also return earlier if no
redraw is actually needed, and improve the comments.

97b5f22a70 When redrawing a whole pane line, fall into tty_draw_line for any 
characters that are not plain ASCII. Fixes redraw issues with partial
tabs and other wide characters when a pane is partly outside the window.

11b6e7844a When MODE_SYNC is on, all terminal updates need to deferred, not just

fe986a52d6 When entering or leaving the alternate screen, discard any pending 
resizes. Improves flicking with scrollbars and programs that leave and
enter the alternate screen on every WINCH like nano. GitHub issue 4772.

00c59041ea Bring in some more floating panes changes - obscured panes need to be 
handled specially in screen_write_* rather than dropping into the client
redraw (tty.c).

1c7e164c22 Add support for applications to use synchronized output mode (DECSET 
2026) to prevent screen tearing during rapid updates. When an
application sends SM ?2026, tmux buffers output until RM ?2026 is received
or a 1-second timeout expires.

9c07903ae9 Correctly remove overwritten wide characters at column 1. 2025-07-18 20:44:13 +00:00

6106a0f2c4 Add an option variation-selector-always-wide to instruct tmux not to 
always interpret VS16 as a wide character and assume the terminal does
likewise. This is behaviour seen in a number of newer terminals' Unicode
14 support but not in older terminals; it seems to be a little
contentious and is currently difficult to detect.

Probably in the long run tmux should pick a behaviour, look at a (new)
terminfo(5) capability to tell it what the terminal will do, and emulate
as required, but at this point I'm not sure that is worth it for
something where support is mixed, seems to be in flux, and that mostly
only matters for emojis.

GitHub issues 3923 and 4475 and others before that.

09f4e43189 Add support for a scrollbar at the side of each pane. New options 
pane-scrollbars turn them on or off, pane-scrollbars-position sets the
position (left or right), and pane-scrollbars-style to set the colours.
Mouse support will come later. From Michael Grant in GitHub issue 4221.

c7e61a01e5 Revamp extended keys support to more closely match xterm and support 
mode 2 as well as mode 1. From Stanislav Kljuhhin (GitHub issue 4038).

This changes tmux to always request mode 2 from parent terminal, change
to an unambiguous internal representation of keys, and adds an option
(extended-keys-format) to control the format similar to the xterm(1)
formatOtherKeys resource.
