729c361aad screen-redraw: stop floating-pane drags from clobbering unrelated panes
window_pane_redraw_floating() (called by every floating-pane drag/resize
command) had two conflicting redraw paths: a precise damage-rectangle
path for the dragged pane, and an unconditional server_redraw_window()
added to fix border-status recomposition (aa6b52ef) that silently
defeated it, redrawing every pane - including retransmitting unrelated
images - on every drag tick.

Chasing the border-status bug back further: it was actually caused by
an upstream regression (824a0729) that split CLIENT_REDRAWWINDOW's
redraw flags into REDRAW_ALL vs. REDRAW_ALL & ~REDRAW_OVERLAY, silently
breaking every literal `flags == REDRAW_ALL` check downstream
(REDRAW_IS_ALL()), including the one that decides whether a pane's
border-status title should be forced to recompose even when its text
hasn't logically changed. Fix this properly instead of reaching for
server_redraw_window() again: decouple overlay-drawing from the shared
flags value (it's only ever read in the one place that repaints an
overlay) so redraw_screen() can pass a genuinely literal REDRAW_ALL for
a window redraw. This also fixes a second-client-attach bug where a new
client's pane titles never appeared until their text changed, since the
per-pane title cache is shared across clients.

Also fixed a real, independent bug in server-client.c found along the
way: `~c->flags & CLIENT_ALLREDRAWFLAGS` is a 6-bit mask, so `~x & MASK`
tests "any bit unset" (almost always true) rather than "no bits set" as
intended - causing damage to be composed and transmitted twice on every
floating-drag tick.

With server_redraw_window() gone, a second problem surfaced: deferred
client redraws (common under a busy tty) still escalated any pending
window damage to a full CLIENT_REDRAWWINDOW redraw, because
server_client_loop() frees w->damage unconditionally every pass with no
tracking of whether a deferred client actually got to consume it. Fix
this by giving each client a copy of missed damage (c->pending_damage,
reusing the existing merge/collapse/16-entry-cap logic damage lists
already have) keyed by the window's id, so a client can compose it
precisely on a later pass instead of resending everything. Window ids
are monotonic and never reused, so a stale id is enough to detect and
discard damage left over from a window the client has since switched
away from or that has been destroyed.

Verified with regress/image-border-status-wipe.sh,
regress/floating-pane-drag-scrollbar-strip.sh,
regress/image-movepane-drag-noflash.sh, and
regress/image-splitwindow-resize-noflash.sh (5 runs each), the full
regress suite (twice), an ASAN/UBSAN debug build, and manual repros for
a window switch and a window destroy mid-defer.

2f1abeeb1a window: fix use-after-free destroying a zoomed window
window_destroy() called window_unzoom() before tearing anything down.
layout_fix_panes() inside that resizes panes, which fires the
pane-resized hook; the hook's event payload takes and drops its own
reference on the window, and since w->references was already 0 at that
point, dropping it reached 0 again and re-entered window_destroy() from
inside itself - freeing w and its panes while the outer call was still
using them.

Pin the window's reference count across window_unzoom() so that
reentrant drop can't reach zero again.

  If no floating panes, reset default starting position, and reset if any part of the pane goes outside the window.
  Empty string for invalid old-style formats causes old iTerm2 versions to crash, so emit "0000," instead.
  Fix session_*_flag format variables which loop over the windows (they should only be false if all windows do not have the flag, not the first one). GitHub issue 5599.
  Do not loop forever if someone tries to give WCHAR_MAX a width, GitHub issue 5602.
  Expand -c for run-shell like the other -c flags, reported by Saúl Nogueras.
  Reset layout manually instead of calling window_unzoom which can go down the notification path and end up double freeing the pane (this was previously removed in 2015 but added back to fix a problem with late destroy - this is a better fix). GitHub issue 5591 from Romain Francoise.

e40ef98b1e image: extend existing placements when a pane grows wider
image_write() only ever creates spans for as much of an image as fit in
the pane at the time it was placed - the rest of the image's pixels are
still retained (struct image is immutable and kept for as long as any
placement references it), but nothing revisited that clipping decision,
so a pane that was too narrow when an image was displayed stayed clipped
forever, even after growing wide enough to fit the rest. Unlike height,
which recovers via ordinary scrollback, there is no equivalent "scroll
right" - this is the only way the extra width is ever recovered.

image_grid_resize_width() finds every placement referenced in a grid's
rows, works out how far its spans already reach and its origin column,
and extends them (via a new image_extend_row(), factored out of
image_write()'s own span-building loop) up to whichever is smaller: the
image's own full width or the new pane width. window_pane_resize() calls
it after a pane grows wider.

f41b983e04 screen-write, tty, popup, window: fix remaining untested damage gaps
Two more fixes based on Michael K. Darling's branch
(github.com/darlingm/tmux, pr5516-regression-fixes), taken as-is -
neither is caught by any test in regress/ yet, found by code review
rather than a failing test:

- screen_write_redraw_cb() (screen-write.c) reported damage for only a
  single row, using ttyctx->ocy as if every fallback redraw were a
  single-cell write. But it's also the callback for cases that can
  legitimately span many rows - a large scroll-region fallback
  (tty_redraw_region(), when tty_large_region() or the pane is
  obscured), a full reset, and entering/leaving the alternate screen.
  For those, only the top row of the affected area ever got marked as
  damaged, leaving the rest stale until an unrelated redraw happened to
  cover it. Changed the shared tty_ctx_redraw_cb typedef to carry
  (py, ny) - the actual row range - and updated every call site to pass
  the range it actually knows about, instead of hardcoding a single
  row.

- window_pane_redraw_floating() (window.c) never refreshed the status
  line after moving/resizing a floating pane, so a status format
  depending on that pane's geometry (e.g. #{pane_width}) could go
  stale until an unrelated status refresh happened. Added a
  server_status_window(w) call.

Also confirmed the window_pane_scrollbar_intersects() parameter
naming cleanup (loop -> wp) discussed earlier was already done in an
earlier "Cleanup." commit - nothing left to do there.

All 9 tests in regress/ plus the two pre-existing floating-pane tests
plus a further 19-test sweep of redraw/tty/input/sync-adjacent
regress tests pass.

b26eeb5229 window: redraw only borders/status on active-pane change
window_set_active_pane() unconditionally called server_redraw_window(w)
on every active-pane change, redrawing every pane's content even though
only the previous and new active pane's border/status appearance
actually changed. Unzooming (which does change every pane's geometry)
still gets the full redraw; otherwise this now only redraws borders and
status.

f255f089fc window: add floating-pane damage/redraw helpers
window_pane_redraw_floating() reports damage for only a floating pane's
old and new rectangle (via redraw_damage_window(), grown by one cell to
cover its border frame - see the "floating" case in screen-redraw.c),
instead of the caller falling back to a full window redraw. Any other
pane whose *scrollbar strip* - not its whole body - intersects either
rectangle still gets PANE_REDRAWSCROLLBAR directly, since scrollbars
aren't covered by the damage system.

d6074895bb screen-redraw, screen-write: add damage-rectangle tracking and composition
Introduce a per-window list of damaged rectangles (struct redraw_damage)
and redraw_damage_window() to record them, redraw_client_damage() to
consume them by composing exactly the damaged cells (via a new
redraw_draw_damage_rect(), which also force-refreshes any pane-status
span it touches, since window_make_pane_status()'s content-diff check
has no way to know the physical cells were disturbed by something else).

redraw_draw_span() now takes an explicit [clip_x, clip_x + clip_n) range
instead of always drawing a span's full width, so a damage rectangle can
redraw just the portion of a span it actually covers.

screen_write_redraw_cb() - the fallback when a write can't be applied
directly to the terminal - now reports damage for just the affected row
via this mechanism, instead of unconditionally flagging the whole pane
for a full redraw.
