d13b69ece4 Change cellused/size to 16 bits and time to 32 bits in grid_line and add 
the OSC 133 positions (size stays the same).

d29aa12117 Replace the notification system with events. Events can carry a payload of 
additional payload (to reduce problems with lifetime of objects) and are
delivered to one or more event sinks. This is more powerful and reduces the
complex dependencies between control mode and hooks. Events are now used for
hooks, control mode notifications and for monitors (set-hook -B).

wait-for can now wait for an event to fire (-E flag, with -F to for filter),
with -v to print the payload, as well as listing (-l) waiting clients on an
event and forcing one to wake (-w).

A few additional hooks are also now available (pane-created, pane-resized, etc)
and some of the existing ones have additional format variables available.

161dbaf1ce Cancel pending resizes and resize immediately when entering alternate

d33d5b7de8 When sync is enabled, we need to mark the whole scroll region dirty if 
there has been any scrolling. GitHub issue 5330.

565db46a19 Instead of fully redrawing the pane when sync ends, only redraw lines 
that have been changed.

c29b41e527 Make pane scrollbars able to auto-hide after a short timeout. This 
replaces the previous "modal" behaviour where the pane would be resized,
which tended to make a mess. Instead, the scrollbar appears when
scrolling or when hovered over with the mouse and disappears a
(configurable) short period later. From Michael Grant.

95afd7549c Rewrite screen-redraw.c to make it tidier and more maintainable. A scene 
is generated and cached in the client: it holds positions and sizes of
panes, borders and so on. The scene is invalidated when a pane is moved
or resized or relevant option is changed. This scene is then drawn to
the client as needed and text and colours are filled in. With Michael
Grant.

d92a479d2f Add a dim= style attribute to dim the colours (as best as tmux is able 
to). GitHub issue 4842.

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.

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.
