inform_compositor_of_window_geometry() calls xdg_surface_set_window_geometry()
unconditionally, but layer-shell surfaces (e.g. those from `kitten panel`) have
no xdg_surface. With hide_window_decorations set to titlebar-only, the panel hits
this geometry call during creation and dereferences the NULL proxy, crashing in
wl_proxy_get_version() with SIGSEGV.
Guard on window->wl.xdg.surface: layer-shell surfaces manage geometry via the
layer surface, so the xdg call is skipped. Normal toplevels are unaffected.
Add a new graphics protocol key, N=1, to request that transmitted
image/frame data is kept only in memory and not written to the graphics
disk cache file.
This is useful for transient high-frequency updates such as video-like
streams, where the latest frame is the only useful data and persisting
each frame to the disk cache causes unnecessary write traffic.
The implementation keeps the existing graphics cache abstraction intact:
memory-only entries can still be read back by animation, composition, and
frame coalescing paths. Only persistence to the disk cache file is skipped.
The default behavior is unchanged when N is omitted or set to zero.
Adds an `equalize` layout action that redistributes split sizes so each
window receives a proportional share of space along each axis.
Also adds an `equalize_on_close` layout option that automatically
equalizes splits whenever a window is closed, keeping the remaining
windows balanced without requiring an explicit key binding.
These two features compose well. For example, to keep splits balanced
at all times - equalizing on every open and close:
enabled_layouts splits:equalize_on_close=true
map ctrl+' combine : launch --location=hsplit --cwd=current : layout_action equalize
map ctrl+/ combine : launch --location=vsplit --cwd=current : layout_action equalize
A standalone key binding for manual rebalancing is also supported:
map ctrl+shift+e layout_action equalize
When scrollbar_jump_on_click is on and the user clicks the track, immediately
jump to the clicked position and begin a drag so holding the button and
moving the mouse continues scrolling. Matches the behavior of Firefox and
GTK apps.
Some window managers (e.g. kwin_x11) clear _NET_WM_STATE when a window
is unmapped/withdrawn. This caused layer shell windows to lose states like
_NET_WM_STATE_ABOVE, _NET_WM_STATE_SKIP_TASKBAR, etc. when hidden and
re-shown via toggle. The result was inconsistent behaviour between the
first show and subsequent shows.
Fix by calling update_wm_hints() before XMapWindow in
_glfwPlatformShowWindow() for layer shell windows, which re-applies all
WM state properties (_NET_WM_STATE, window type, strut, size hints)
before each map operation.
Recognize CSI ? 5 W as DECST8C, which resets the active screen's tab
stops to the default of every 8 columns. Other CSI W variants continue
to produce a parse error.

Previously, every window resize reinitialised the tab stops to the
default of every 8 columns, discarding any stops set via HTS or cleared
via TBC. ECMA-48 only treats RIS, DECSTR, and DECCOLM as events that
reset tab stops, and other terminal emulators all preserve user-set
stops across an interactive resize.
Copy the surviving prefix of the previous tab stops into the freshly
allocated array on both main and alt screens. Newly added columns when
growing the window keep the default every 8 columns pattern. Also point
the active tabstops pointer at the alt screen's array when a resize
happens while the alt screen is active, instead of unconditionally
resetting it to the main screen's array.
