...to start <command> on startup and to terminate the compositor when
<command> exits.
This is useful for session management as it allows the session client (for
example `lxqt-session`) to terminate labwc - be exiting itself.
Under X, xinit starts the server and keeps it alive for as long as
lxqt-session runs. Thus either the session client starts the Window
Manager, or the Window Manager can be launched independently first. On
Wayland, the Compositor is both Display Server and Window Manager, so the
described session management mechanisms do not work because the Compositor
needs to be running before the session can function.
As some session clients support both X11 and Wayland, this command line
option avoids re-writes and fragmentation.

Add custom field with subset of printf style formatting
to replace the original field formats.
Example:
<windowSwitcher preview="no" outlines="no" allWorkspaces="yes">
<fields>
<field content="custom" format="foobar %b %3s %-10o %-20W %-10i%t" width="100%" />
</fields>
</windowSwitcher>
Mono space font recommended. May need OSD width adjusted

When growing or shrinking a view by snapping to an edge, a client may
ignore the requested size and instead keep its original size or
substitute a different (possibly constrained) size. In this case, the
view may not actually contact the snapped edge, and a subsequent snap
attempt will just keep re-trying (and failing) to contact the same ege.
To mitigate this, remember the last-snapped view, snapping direction and
offset of the snapping edge in snap.c; when re-attempting a snap for the
same view in the same direction, ignore the edge that was last "hit", to
allow snapping to progress beyond the problematic edge.
This fixes an issue detected by the static analyzer.
Rather than setting up the new popup as usual return
a wayland error to the client and destroy the popup.
This fixes an issue detected by the static analyzer.
It currently is not a real bug but it could become
one in the future if `add_toggled_icon()` is called
before `add_scene_button()`.
Rather than having `add_toggled_icon()` go through
the list, find the root button and then fetch its
node descriptor just supply the button as argument.
Fill with the background color first only if the background color is
opaque. This is necessary for subpixel rendering to work properly (it
does not work on top of transparency).
However, if the background color is not opaque, leave the buffer
unfilled (completely transparent) since the background is already
rendered by the scene element underneath. In this case we have to
disable subpixel rendering.
v2: use 0.999 alpha cutoff and fix CodeStyleCheck
Fixes: (the rest of) #1684
Add ability to set width with percentage of monitor instead of just pixels.
With this the OSD sizes itself properly on both my 4k and 2k monitors.
example: 50% or 75% instead of 600, max 100%
wlr_scene_rects expect their color to be pre-multiplied
while cairo_set_source_rgba() expects them to not be
pre-multiplied. With this patch we now use premultiplied
colors internally by default and then reverse it when
setting cairo colors.
This ensures the titlebar uses a consistent color in case
it was defined with some transparency by the user.

...where dnd does not finish properly on cursor-button-release if there
is no surface under the cursor such as on the desktop when no background
client is running.

Fixes: #1673
This fixes that, when a CSD window is dragged into below waybar and the cursor
button is released, the cursor focus is moved from the CSD window to waybar and
a release event is sent to waybar, not original CSD window.
...and unify region overlay and snap-to-edge overlay into overlay.c.
Snap-to-edge overlay is delayed for 500ms to prevent flickering when
the view is dragged from an output to another (demo in discussion labwc#1613).
This also fixes a bug that region overlay is not shown when a modifier
key is re-pressed.
...because click on different parts of a client should not be
interpreted as a double click.
Previously only cursor-button and view were validated to be the same
between clicks. This resulted in, for example a click on the client
surface itself quickly followed by a click on the SSD titlebar being
interpreted as a double-click on the titlebar.
Fixes: #1657
...for the following reasons:
1. We interpret 'normal input-focus semantics' for clients with on-demand
keyboard interactivity to means that a surface receives input focus on
cursor-button-press AND on map (the latter previously missing), just
like a normal window would. In this regard, we do not differentiate
between layers.
2. Most layer-surfaces set the keyboard interactivity at a similar time to
their first (and normally only) map, so the absence of an explicit
attempt to focus on map does not make a difference. However, for a
long-running layer-shell client (such as lxqt-runner) which sets the
interactivity on launch and then maps/unmaps many times throughout its
lifetime, a specific focus-attempt is required on map to avoid the
client itself having to keep resetting its interactivity to grab the
keyboard on map.
3. Compositors like sway and river process focus (for clients with
keyboard-interactivity) in their map-handlers, so this makes for a
common approach.
Fixes: #1653
...for example `Fall Guys`. It is believed to be caused by setting
override-redirect on an xwayland-surface with a child window, thus
breaking the way root-toplevels are obtained.

...and on unmap.
Add `try_to_focus_next_layer_or_toplevel()` which does the following
(in order of precedence):
- Give focus to last added overlay/top layer-shell client with exclusive
interactivity on the output nearest the pointer (normally the one where
the users is currently working). The reason for not considering clients
on all outputs is that giving focus to a client on another output may be
confusing to the user.
- Give focus to topmost toplevel if one exists (this was done previously
anyway).
This means that the logic described in 2ff026b will be used when a
layer-surface is pressed on with a cursor button. For example, a surface
with on-demand keyboard interactivity will not steal focus from a client
with exclusive keyboard interactivity.
Use the following logic:
- Exclusive: Grant regardless of layer (previously it was only given if
in top or overlay layers) AND grant if in the same or higher layer
(nearer overlay) compared with other clients with exclusive
interactivity.
- On-demand: Grant only if no other layer-shell client has exclusive
keyboard interactivity. Previously it was treated the same as
exclusive.
- None: Unset focus if the commit associated with the 'none' came from
the currently focused layer. Previously it was just unset regardless.
