Keep retained indexed SIXEL data and the bounded per-terminal output cache.
Use the cleaned-up decoder and RGBA encoder from image_merge, including
parser memory limits, pixel-size handling and references for pending output.
Match retained SIXEL scaling to the shared image cell footprint and emit
black definitions for undefined colour registers.
Keep Kitty input, output, layers and placeholders. Adapt backend selection,
flags, drawing and cleanup to the callbacks and Iscrl capability. Keep the
pane-status repaint with the requested XXX comment.
Replace the elaborate fallback with image_merge's implementation, removing
its caches, sample structures, quadrant/sextant features and ACS additions.
Keep the image_merge regressions and adapt the Kitty tests to the simpler
fallback. Use skip status 101 and disable Python bytecode for image tests.
Small changes still outside image_merge:
- Guard zero-height synchronized redraws before bit_nset.
- Select the image backend when the tty opens.
- Enable imagescroll by default for Kitty and Ghostty.
- Keep the explanatory manual-window pixel-size comment (comment only).
- Keep the additional SIXEL fixtures and visual test tools.
Validation: image-enabled and disabled builds; 31 image and 13 related
regressions pass normally and under ASAN. All image tests skip without
images. Focused palette, parser, scaling, transparency and Kitty layer
tests also pass after the retained-output adjustments. Diff checks clean.
* refs/remotes/tmux-openbsd/master:
Respect the ncv capability and do not combine attributes and colours that will not work, reported by Joan Bruguera Micó in GitHub issue 5727.
Clear implied Meta when discarding BackTab modifiers, GitHub issue 5730 from Joan Fabrégat.
Do not treat compact padding cells as width 1, make them width 0. GitHub issue 5718 from dustgle at gmail dot com.
Do not reuse old session group names when a new session is the same as its original session, GitHub issue 5704.
Support Kitty and SIXEL input and output with grid-resident image layers, history and copy-mode integration, text fallback rendering, and damage-rectangle redraws.
Consolidate the image work through 250f96b4b onto the redraw-damage-rectangles-new base, excluding the superseded redraw implementation and its historical merges. The original history is preserved in backup/4902-image-support-before-master-rebase-20261003.
* refs/remotes/tmux-openbsd/master:
Use window-status-separator in second and theird status lines, GitHub issue 5672. Also match width of session name correctly.
Fix color range check, from Vaibhav Aggarwal.
Do not lose a pending pane resize when entering the alternate screen, from mml00 dot work at gmail dot com.
Adjust widths of a few codepoints incorrectly set to double width, from Sidney Cammeresi.
* refs/remotes/tmux-openbsd/master:
Sync redraw should use the given rows not the scroll region now.
Instead of redrawing the entire pane or scene when moving or redrawing a pane, add damage rectangles and redraw only the affected spans. From Michael Grant.
Do not leak client if lost before configuration is loaded, and do not load multiple times. GitHub issues 5661 and 5662 from Alexandre Fiori.
Restore the zoom when swap-pane refuses a floating pane, GitHub issue 5660 from Alexandre Fiori.
Do not use client for copy-mode -S if NULL, reported by Martin Vlach.
* refs/remotes/tmux-openbsd/master:
Add a feature for mintty's application escape to avoid dodgy terminals whinging about not supporting it, GitHub issue 5626 from Pete Dietl.
Only rely on the previous line wrapping when the cursor is actually on it, GitHub issue 5625 from Ben Maurer.
Correctly write Z indexes to v2 layouts if zoomed, GitHub issue 5624.
Do not leak waiting clients (in wait-for) if they are killed, GitHub issue 5614.
* refs/remotes/tmux-openbsd/master:
Remove popups and all the associated overlay machinery (they were the last user of it). display-popup stays but becomes an (undocumented) compatibility command to open a floating pane.
Fix typo (too few 0s) in CLIENT_CONTROL_DISCARD, from someone in GitHub issue 5622.
* refs/remotes/tmux-openbsd/master:
Add a clear-on-attach option which when turned off scrolls away the existing terminal state instead of entering the alternate screen. This is useful in environments where tmux is started as a login shell but it is important that any pre-tmux messages are still visible. GitHub issue 5508 from Josef Řídký.

Remove the active-pane flag for now, there are some gaps in how this works and I don't like it. May come back in a different form (maybe just for windows).

build: don't exit

Use _exit in child after fork, from Yayo Razo in GitHub issue 5376.
Add missing calloc check and use fatal. Prompted by a similar change from Yayo Razo.
actions: use published openbsd-git as base update
github actions: automate updates
Do not make pty fds blocking again until all the data has been consumed or control mode clients can get stuck, GitHub issue 5356 from Ben Maurer.
Add formats and events for OSC 133 commmands, as well as a -T flag to set-hook -B to only fire when the format is true.
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.
or more colours. Currently based these on emacs but they could change.
Terminals with fewer colours use the ANSI colours. A new "theme" option
overrides the detected theme (set to "terminal" to go back to ANSI
colours).
