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.

# Regression test for the imagescroll terminal-feature (tty-features.c),
|
|
# Kitty side - see image-sixel-region-scroll.sh for the SIXEL side of the
|
|
# same feature.
|
|
#
|
|
# The Kitty backend used to hardcode IMAGE_BACKEND_SCROLLS unconditionally
|
|
# (image.c), so tmux always trusted the terminal to have moved a Kitty
|
|
# placement along with the rest of a scrolling region, with no way to turn
|
|
# that assumption off. At least Windows Terminal does not actually do
|
|
# this: it drops the placement entirely on a plain newline- or
|
|
# reverse-index-driven scroll (though not on a delete-line/insert-line
|
|
# scroll simulation, which goes through a different, always-redraw path).
|
|
# imagescroll now gates Kitty exactly like SIXEL: scrolling must not
|
|
# retransmit the placement when the client's terminal has imagescroll (the
|
|
# previously unconditional behaviour), and must retransmit it without (the
|
|
# default for any terminal not individually confirmed and added to
|
|
# tty-features.c's table) - the escape hatch this test exists to prove is
|
|
# actually wired up for Kitty too.
