7555688d8d display: Set xattr on focus window cgroup dir
Added a function `meta_window_set_inactive_since` it sets
xattr on the cgroup directory for the given MetaWindow.

Resource management daemons can then monitor these changes on xattr
and make allocation decisions accordingly.

c2efe25597 window: Add cgroup management to MetaWindow
Currently the only way to get cgroup for a MetaWindow is to get it's
PID and perform a bunch of file accesses and string manipulations.
This is especially not feasible if we want to get the cgroup every
time a MetaWindow has gained or lost focus.

A solution to this is to cache the GFile for a cgroup path.
The creation and access of this GFile is handled by
`meta_window_get_unit_cgroup` function.

`meta_window_unit_cgroup_equal` is a utility function which allows
us to compare whether two MetaWindows belong to the same cgroup.

d17e9adc73 context: Add (hidden) --unsafe-mode option
When running gnome-shell, it is possible to toggle unsafe-mode in
looking glass. We'll eventually start using the property in mutter
as well, so to make stand-alone debugging easier, also expose it
as a hidden command line option.

c62e86cb23 context: Add :unsafe-mode property
We are going to restrict several sensitive D-Bus APIs to a set
of allowed callers (like Settings or portal implementations).

Add an :unsafe-mode property to the context to allow turning off
those restrictions temporarily, in order to not get in the way
of development/debugging.

41d1a8407e keybindings: Remove 'panel-run-dialog' handler

ed391eb06b window: Make default focus window on each workspace appear focused
Makes workspace transitions in gnome-shell look more seamless, since
both outgoing and incoming workspace have focused windows.

This is only done for click focus mode, since it's not known which
window would be focused for the other modes.

Track the state and recompute it when it changes, to avoid redrawing
the windows needlessly.

7afefbbb61 workspace: Add meta_workspace_get_default_focus_window()
Each workspace has a window that will be focused when switching to that
workspace. Add a function to retrieve that window.

This is only relevant for click-to-focus focus mode, since with the two
other modes no window will be focused upon switching, and will only gain
focus when hovered.

This will be used in the next commit to make this window appear focused.

537e2dfafe core/selection: Cancel selection transfer requests after a timeout
When a selection owner advertises a mime type, but does not provide the
content upon a request for the mime type content, the requesting side
might wait indefinitely on the content.

d3b7d8df0d wayland: Initialize in a single step
Before we first created the MetaWaylandCompositor instance, which would
repare Clutter/Cogl so they could initialize and turn on Wayland display
server features, then later to initialize the rest. Now that part is
done by the Wayland infrastructure itself, so we don't need the early
initialization. Simplify things a bit by centralizing it all into a
single meta_wayland_compositor_new() call.

9b25248c96 main: Force Xwayland startup if not on systemd
In non-systemd managed session we are unable to start services on
demand. Instead, gnome-session will start everything at login time,
including any X11 related service (i.e. gsd-xsettings).

However, in order to start gsd-xsettings, Xwayland needs to be started
already. Otherwise it will connect to GNOME_SETUP_DISPLAY and login will
hang at that point.

Fix this by detecting whether mutter is running in a systemd unit. If it
is, we assume that we are systemd managed and the machinery to start the
services works fine. If not, we assume that the session management may
unconditionally try to start X11 related services and Xwayland must be
started in order to not block this.

Especially important here is setting grab_frame_action back to FALSE,
since this will constrain window-titlebars to the panel. We set this to
TRUE on some grabs, for example when resizing, but not when moving
windows. Since this remained being set to TRUE, it would also constrain
non-grab window movements, like calling MetaWindow.move_frame(), which
is used by gnome-shells OSK. By resetting it back to FALSE after a grab,
the OSK can now always move non-maximized windows to the position it

2432508db7 core: Account for the globally active input case
Commit afa43154 tried to make sure the focus was properly changed when
calling focus_default_window() by checking the focused window just after
trying to set the focus.

However, the X11 “Inter-Client Communication Conventions Manual” version
2.0 (ICCCM 2 for short) states that some X11 client may want to use a so
called “globally active input” model in which case the client expects
keyboard input and set input focus even when it's not one of its own
window.

To comply with this, when dealing with such clients, mutter will not
change the focus and send a WM_TAKE_FOCUS message instead.

That mechanism will defeat the logic introduced by commit afa43154
because the focused window is not changed in this case. As a result, the
input focus will fallback to the no-focus window.

To avoid this, only check that the focus change occurred for windows
using a synchronous focus model.

v2: Split specific test for "globally active input" model (Florian).
v3: Remove the check for window->unmanaging which is useless (Jonas).

GObject signals pass the emitting GObject as the first argument to

to remove MetaScreen with commit 1d5e37050d,
the "screen" argument was replaced with a "display" argument instead of
being removed completely. This made us call the signal handlers with two
identical MetaDisplay arguments, which is very confusing and actually
wasn't handled in a grab-op-begin handler in gnome-shell.

afa431547b core: Make sure focus_default_window() worked
The function focus_default_window() optionally takes a MetaWindow
argument denoting a window that should not be focused.

That function calls focus_ancestor_or_top_window() which in turn
calls meta_window_focus() to pass focus to another window.

However meta_window_focus() gives no guarantee that the given window
will end up being the one focused, and can fail in various and creative
ways.

If that fails, we could possibly end up with the focus window being the
one to avoid, while the caller assumes focus was changed, going as far
as asserting that fact like meta_window_unmanage() does.

As a result, mutter may abort simply because meta_window_focus() failed
to set focus on the expected window.

To avoid that issue, check that the focus did not end up on the window
that we explicitly did not want, and if that's the case, simply fallback
to the default focus window.

that each show/hide call dealt with the stack in isolation, meaning if

potentially doing synchronous calls to the X server while doing so.

Avoid the most severe stalls by freezing the stack while calculating

00cbcb7ba1 core: Centralize cursor renderer and tracker updates
These use now more of a "pull" model, where they receive update
notifications and the relevant input position is queried, instead
of the coordinates being passed along.

This allows to treat cursor renderers all the same independently
of the device they track. This notifying of position changes should
ideally be more backend-y than core-y, a better location will be
figured out in future commits.

27131198c7 window: Fix size hints with CSD
Commit 03c69ed8 ("Do not go past size hints on resize") was meant to
ensure the size hints set by the client would be honored during resize,
as going past those values could cause the window to move on resize.

However, it did so by calling ensure_size_hints_satisfied() which works
with the frame rect rather than the client rect. As a result, the
minimum size enforced would end up being larger than expected with
client-side decorations.

Use meta_window_maybe_apply_size_hints() instead which automatically
adjusts for client size.

7ab3eac0e2 constraints: Use "orig" rectangle for interactive resize
Bug 448183 fixed an issue with _NET_WM_MOVERESIZE_WINDOW not moving a
window by basing the resize on the current (new) rectangle instead of
the original rectangle.

While this fixes the issue with _NET_WM_MOVERESIZE_WINDOW, this also
causes windows with a size increment to move when the resize also
implies a move, such windows might drift while resizing.

Make sure to use the current rectangle for non-interactive resizes only.

03c69ed8cf window: Do not go past size hints on resize
On interactive resize, mutter calculates the difference in size based on
the pointer location and relies on window constraints to ensure the
minimum size is honored.

Wayland however does asynchronous window configuration, meaning that not
checking for size hints early enough may lead to the window moving as
the locations was initially computed on a size which will be invalidate
by the client eventually.

Make sure to respect the client size hint on update_resize() so that we
don't end up with a window moving unexpectedly when the client
eventually acked the configuration.

f894f5cc13 wayland: Add API to launch trusted clients
Allowing code from inside mutter to create a child process and
delegate on it some of its tasks is something very useful. This can
be done easily with the g_subprocess and g_subprocess_launcher classes
already available in GLib and GObject.

Unfortunately, although the child process can be a graphical program,
currently it is not possible for the inner code to identify the
windows created by the child in a secure manner (this is: being able
to ensure that a malicious program won't be able to trick the inner
code into thinking it is a child process launched by it).

Under X11 this is not a problem because any program has full control
over their windows, but under Wayland it is a different story: a
program can't neither force their window to be kept at the top (like a
docker program does) or at the bottom (like a program for desktop icons
does), nor hide it from the list of windows. This means that it is not
possible for a "classic", non-priviledged program, to fulfill these
tasks, and it can be done only from code inside mutter (like a
gnome-shell extension).

This is a non desirable situation, because an extension runs in the
same main loop than the whole desktop itself, which means that a
complex extension can need to do too much work inside the main loop,
and freeze the whole desktop for too much time. Also, it is important
to note that javascript doesn't have access to fork(), or threads,
which means that, at most, all the parallel computing that can do is
those available in the _async calls in GLib/GObject.

Also, having to create an extension for any priviledged graphical
element is an stopper for a lot of programmers who already know
GTK+ but doesn't know Clutter.

This patch wants to offer a solution to this problem, by offering a
new class that allows to launch a trusted child process from inside
mutter, and make it to use an specific UNIX socket to communicate
with the compositor. It also allows to check whether an specific
MetaWindow was created by one of this trusted child processes or not.

This allows to create extensions that launch a child process, and
when that process creates a window, the extension can confirm in a
secure way that the window really belongs to that process
launched by it, so it can give to that window "superpowers" like
being kept at the bottom of the desktop, not being listed in the
list of windows or shown in the Activities panel... Also, in future
versions, it could easily implement protocol extensions that only
could be used by these trusted child processes.

Several examples of the usefulness of this are that, with it, it
is possible to write programs that implements:

- desktop icons
- a dock
- a top or bottom bar
...

all in a secure manner, avoiding insecure programs to do the same.
In fact, even if the same code is launched manually, it won't have
those privileges, only the specific process launched from inside
mutter.

Since this is only needed under Wayland, it won't work under X11.

f712387325 compositor: use XDG_CONFIG_HOME as initial lookup path for xkb
Using XDG_CONFIG_HOME allows users to place their keyboard configuration into
their home directory and have them loaded automatically.
libxkbcommon now defaults to XDG_CONFIG_HOME/xkb/ first, see
https://github.com/xkbcommon/libxkbcommon/pull/117

However - libxkbcommon uses secure_getenv() to obtain XDG_CONFIG_HOME and thus
fails to load this for the mutter context which has cap_sys_nice.
We need to manually add that search path as lookup path.

As we can only append paths to libxkbcommon's context, we need to start with
an empty search path set, add our custom path, then append the default search
paths.

The net effect is nil where a user doesn't have XDG_CONFIG_HOME/xkb/.

476ef76de6 tests/test-runner: Add 'assert_size' command
The 'assert_size' command checks that the size of the window, both
client side and compositor side, corresponds to an expected size set by
the test case.

The size comparison can only be done when the window is using 'csd', in
order for both the client and server to have the same amount of
understanding of the title bar. For ssd, the client cannot know how
large the title bar, thus cannot verify the full window size.

Sizes can be specified to mean the size of the monitor divided by a
number. This is that one can make sure a window is maximized or
fullscreened correctly.

551a57ed7f Add read-only anonymous file abstraction MetaAnonymousFile
Add MetaAnonymousFile, an abstraction around anonymous read-only files.
Files can be created by calling meta_anonymous_file_new(), passing the
data of the file. Subsequent calls to meta_anonymous_file_open_fd()
return a fd that's ready to be sent over the socket.

When mapmode is META_ANONYMOUS_FILE_MAPMODE_PRIVATE the fd is only
guaranteed to be mmap-able readonly with MAP_PRIVATE but does not
require duplicating the file for each resource when memfd_create is
available. META_ANONYMOUS_FILE_MAPMODE_SHARED may be used when the
client must be able to map the file with MAP_SHARED but it also means
that the file has to be duplicated even when memfd_create is available.

65a6c4c361 compositor: Add support for direct scanout of Wayland surfaces
Try to bypass compositing if there is a fullscreen toplevel window with
a buffer compatible with the primary plane of the monitor it is
fullscreen on. Only non-mirrored is currently supported; as well as
fullscreened on a single monitor. It should be possible to extend with

It does this by introducing a new MetaCompositor sub type

dc4fe780f7 display: Initialize MetaCompositor in two steps
MetaCompositor is the place in mutter that manages the higher level
state of compositing, such as handling what happens before and after
paint. In order for other units that depend on having a compositor
instance active, but should be initialized before the X11 implementation
of MetaCompositor registers as a X11 compositing manager, split the
initialization of compositing into two steps:

 1) Instantiate the object - only construct the instance, making it
    possible for users to start listening to signals etc
 2) Manage - this e.g. establishes the compositor as the X11 compositing
    manager and similar things.

This will enable us to put compositing dependent scattered global
variables into a MetaCompositor owned object.

For now, compositor management is internally done by calling a new
`meta_compositor_do_manage()`, as right now we can't change the API of
`meta_compositor_manage()` as it is public. For the next version, manual
management of compositing will removed from the public API, and only
managed internally.

8df3b21a51 window: Check aliveness a bit less aggressively
Currently we check whether a window is alive everytime it's focused.
This means that an application that doesn't respond to the check-alive
event during startup always showing the "application froze" dialog,
without the user ever trying to interact with it.

An example where this tends to to happen is with games, and for this
particular scenario, it's purely an annoyance, as I never tried to
interact with the game window in the first place, so I don't care that
it's not responding - it's loading.

To avoid these unnecessary particular "app-is-frozen" popups, remove the
alive check from the focus function, and instead move it back to the
"meta_window_activate_full()" call. To also trigger it slightly more
often, also add it to the path that triggers the window focus when a
user actively clicks on the window.

This means that we currently check whether a window is alive on:

  * Any time the window is activated. This means e.g. alt-tab or
    selecting the window in the overview.
  * The user clicks on the window.

Note that the second only works for an already focused window on
Wayland, as on X11, we don't refocus it. This particular case isn't
changed with this commit, as we didn't call meta_window_focus() to begin
with here.

d4c070da88 window: Really propagate effective on-all-workspaces setting to transients
Commit cda9579034 fixed a corner case when setting the initial workspace
state of transient windows, but it still missed a case:

should_be_on_all_workspaces() returns whether the window should be on all
workspaces according to its properties/placement, but it doesn't take
transient relations into account.

That means in case of nested transients, we can still fail the assert:

 1. on-all-workspaces toplevel
 2. should_be_on_all_workspaces() is TRUE for the first transient's parent,
    as the window from (1) has on_all_workspaces_requested == TRUE
 3. should_be_on_all_workspaces() is FALSE for the second transient's
    parent, as the window from (2) is only on-all-workspace because
    of its parent

We can fix this by either using the state from the root ancestor
instead of the direct transient parent, or by using the parent's
on_all_workspaces_state.

The latter is simpler, so go with that.

23da6c2426 keybindings: Check the special modifiers specifically
Make sure it is only the special modifier (hardcoded to 1 currently)
which is being pressed (not counting locked modifiers) before notifying
that the special modifier is pressed, as we are interested in it being
pressed alone and not in combination with other modifier keys.

This helps in two ways:
- Pressing alt, then ctrl, then releasing both won't trigger the locate
  pointer action.
- Pressing alt, then ctrl, then down/up to switch workspace won't interpret
  the last up/down keypress as an additional key on top of the special ctrl
  modifier, thus won't be forwarded down to the focused client in the last
  second.

67dd0b4fec keybindings: Avoid double calls to process_event() on the same event
If you first press a key that triggers the "special modifier key" paths
(ctrl, super), and then press another key that doesn't match (yet?) any
keybindings (eg. ctrl+alt, super+x), the second key press goes twice
through process_event(), once in the processing of this so far special
combination and another while we let the event through.

In order to keep things consistent, handle it differently depending on
whether we are a wayland compositor or not. For X11, consider the event
handled after the call to process_event() in process_special_modifier_key().
For Wayland, as XIAllowEvents is not the mechanism that allows clients see
the key event, we can just fall through the regular paths, without this
special handling.

d08a8de265 window: Implement asynchronous popup moving
This commits adds support on the MetaWindow and constraints engine side
for asynchronously repositioning a window with a placement rule, either
due to environmental changes (e.g. parent moved) or explicitly done so
via `meta_window_update_placement_rule()`.

This is so far unused, as placement rules where this functionality is
triggered are not yet constructed by the xdg-shell implementation, and
no users of `meta_window_update_placement_rule()` exists yet.

To summarize, it works by making it possible to produce placement rules
with the parent rectangle a window should be placed against, while
creating a pending configuration that is not applied until acknowledged
by the client using the xdg-shell configure/ack_configure mechanisms.

An "temporary" constrain result is added to deal with situations
where the client window *must* move immediately even though it has not yet
acknowledged a new configuration that was sent. This happens for example
when the parent window is moved, causing the popup window to change its
relative position e.g. because it ended up partially off-screen. In this
situation, the temporary position corresponds to the result of the
movement of the parent, while the pending (asynchronously configured)
position is the relative one given the new constraining result.

25c9e66c73 xwayland: Do not block on Xwayland initialization
We artificially made Xwayland initialization synchronous, as we used
to rely on MetaX11Display and other bits during meta_display_open().
With support for Xwayland on demand and --no-x11, this is certainly
not the case.

So drop the main loop surrounding Xwayland initialization, and turn
it into an async operation called from meta_display_init_x11(). This
function is turned then into the high-level entry point that will
get you from no X server to having a MetaX11Display.

The role of meta_init() in Xwayland initialization is thus reduced
to setting up the sockets. Notably no processes are spawned from here,
deferring that till there is a MetaDisplay to poke.

The check-alive feature is there for the user to be able to terminate

When using an application that has these issues, the GUI showed in

44ae38599f wayland: Move MetaWindow ownership to window owning roles
There are two surface roles owning a MetaWindow: MetaWaylandShellSurface
(basis of MetaWaylandXdgToplevel, MetaWaylandXdgPopup,
MetaWaylandWlShellSurface, etc), and MetaXwaylandSurface.

With these two role types, the MetaWindow has two different types of
life times. With MetaWaylandShellSurface, the window is owned and
managed by the role itself, while with MetaXwaylandSurface, the
MetaWindow is tied to the X11 window, while the Wayland surface and its
role plays more the role of the backing rendering surface.

Before, for historical reasons, MetaWindow was part of
MetaWaylandSurface, even though just some roles used it, and before
'wayland: Untie MetaWindowXwayland lifetime from the wl_surface' had
equivalent life times as well. But since that commit, the management
changed. To not have the same fied in MetaWaylandSurface being managed
in such drastically different ways, rearrange it so that the roles that
has a MetaWindow themself manages it in the way it is meant to; meaning
MetaWaylandShellSurface practically owns it, while with Xwayland, the
existance of a MetaWindow is tracked via X11.

1c89fce30e stack: Allow promoting transient windows to their parent's layer
When a window that should be stacked above another one is placed in a lower
layer than the other window, we currently allow promoting it to the higher
layer when it has a "transient type". We should do the same when the window
is an actual transient of the other window.

This is particularly relevant for wayland windows, where types play a
much smaller role: Transient windows like non-modal dialogs (and since
commit 666bef7a, popup windows as well) currently end up underneath their
always-on-top parent.

92375c75f8 cleanup: Use g_clear_signal_handler() where possible
This is inspired by 98892391d7 where the usage of
`g_signal_handler_disconnect()` without resetting the corresponding
handler id later resulted in a bug. Using `g_clear_signal_handler()`
makes sure we avoid similar bugs and is almost always the better
alternative. We use it for new code, let's clean up the old code to
also use it.

A further benefit is that it can get called even if the passed id is
0, allowing us to remove a lot of now unnessecary checks, and the fact
that `g_clear_signal_handler()` checks for the right type size, forcing us
to clean up all places where we used `guint` instead of `gulong`.

No functional changes intended here and all changes should be trivial,
thus bundled in one big commit.

84cc89e19a wayland: Set dummy selection source on .set_selection(null)
Requesting a selection with a NULL data source means "unset the clipboard",
but internally we use an unset clipboard as the indication that the
clipboard manager should take over.

Moreover, this unset request may go unheard if the current owner is someone
else than the MetaWaylandDataDevice.

Instead, set a dummy data source with no mimetypes nor data, this both
prevents the clipboard manager from taking over and ensures the selection
is replaced with it.

The MetaSelectionSourceMemory was also added some checks to allow for this
dummy mode.

4b88c1832a events: Sync pending pointer events without a window
Mutter issues a synchronous grab on the pointer for unfocused client
windows to be able to catch the button events first and raise/focus
client windows accordingly.

When there is a synchronous grab in effect, all events are queued until
the grabbing client releases the event queue as it processes the events.

Mutter does release the events in its event handler function but does so
only if it is able to find the window matching the event. If the window
is a shell widget, that matching may fail and therefore Mutter will not
release the events, hence causing a freeze in pointer events delivery.

To avoid the issue, make sure we sync the pointer events in case we
can't find a matching window.

76f2579e44 keybinding: Check for handler functions as well
With the addition of the locate-pointer special keybinding (defaults to
the [Control] key), we have now two separate special modifier keys which
can be triggered separately, one for the locate-pointer action and
another one for overlay.

When processing those special modifier keys, mutter must ensure that the
key was pressed alone, being a modifier, the key could otherwise be part
of another key combo.

As result, if both special modifiers keys are pressed simultaneously,
mutter will try to trigger the function for the second key being
pressed, and since those special modifier keys have no default handler
function set, that will crash mutter.

Check if the handler has a function associated and treat the keybinding
as not found if no handler function is set, as with the special modifier
keys.

8f242f8bf0 core: Fix multiple reparent requests handling
If window decoration is modified within a short period of time, mutter
sometimes starts processing the second request before the first
UnmapNotify event has been received. In this situation, it considers
that the window is not mapped and does not expect another UnmapNotify /
MapNotify event sequence to happen.

This adds a separate counter to keep track of the pending reparents. The
input focus is then restored when MapNotify event is received iff all
the expected pending ReparentNotify events have been received.

A base type shouldn't know about sub types, so let MetaDisplay make
the correct choice of what type of MetaCompositor it should create. No
other semantical changes introduced.

f37a172dc7 events: No UI frame button press events for Wayland
When double clicking to un-maximize an X11 window under Wayland, there
is a race between X11 and Wayland protocols and the X11 XConfigureWindow
may be processed by Xwayland before the button press event is forwarded
via the Wayland protocol.

As a result, the second click may reach another X11 window placed right
underneath in the X11 stack.

Make sure we do not forward the button press event to Wayland if it was
handled by the frame UI.

a0bdf44c2d core: Do not crash on untimely stack queries for X11 windows
Some meta_later operations may happen across XWayland being shutdown,
that trigger MetaStackTracker queries for X11 XIDs. This crashes as
the MetaX11Display is already NULL.

Return a NULL window in that case, as in "unknown stack ID".

08c6b801d2 core: Exit early on keybindings if this is a wayland compositor
Fixes a thinko in commit 79b5ece2. It is meant to bail out early

but this condition was inverted.

141373f0ba wayland: Implement on-demand start of Xwayland
The Xwayland manager now has 4 distinct phases:
- Init and shutdown (Happening together with the compositor itself)
- Start and stop

In these last 2 phases, handle orderly initialization and shutdown
of Xwayland. On initialization We will simply find out what is a
proper display name, and set up the envvar and socket so that clients
think there is a X server.

Whenever we detect data on this socket, we enter the start phase
that will launch Xwayland, and plunge the socket directly to it.
In this phase we now also set up the MetaX11Display.

The stop phase is pretty much the opposite, we will shutdown the
MetaX11Display and all related data, terminate the Xwayland
process, and restore the listening sockets. This phase happens
on a timeout whenever the last known X11 MetaWindow is gone. If no
new X clients come back in this timeout, the X server will be
eventually terminated.

The shutdown phase happens on compositor shutdown and is completely
uninteresting. Some bits there moved into the stop phase as might
happen over and over.

This is all controlled by META_DISPLAY_POLICY_ON_DEMAND and
the "autostart-xwayland" experimental setting.

0c5866a9e1 core: Avoid queueing a stack operation on the frame when the X11 is closing
When rushing to unmanage X11 windows after the X11 connection is closed/ing,
this would succeed at creating a stack operation for no longer known windows.
Simply avoid to queue a stack operation if we know it's meaningless.

500a692e3b core: Manage only X11 windows when (re)starting
What "restart" means is somewhat different between x11 and wayland
sessions. A X11 compositor may restart itself, thus having to manage
again all the client windows that were running. A wayland compositor
cannot restart itself, but might restart X11, in which case there's
possibly a number of wayland clients, plus some x11 app that is
being started.

For the latter case, the assert will break, so just make it
conditional. Also rename the function so it's more clear that it
only affects X11 windows.

ca51cd8488 core: Prepare MetaStackTracker for X11 display being closed
If the display is closed prematurely, go through all windows that
look X11-y and remove them for future calculations. This is not
strictly needed as Xwayland should shut down orderly (thus no client
windows be there), but doesn't hurt to prepare in advance for the
cases where it might not be the case.

We don't strictly need it for wayland compositors, yet there are

skip those on the high level code (where "is it x11" decisions
are taken) like we do with passive button grabs.

cda9579034 core: propagate the effective on-all-workspaces setting to transient window
Commit 09bab98b1e tried to avoid several workspace changes while in
window construction, but it missed a case:

If we have a window on a secondary monitor with no workspaces enabled
(so it implicitly gets on_all_workspaces = TRUE without requesting it)
and trigger the creation of a second window that has the first as
transient-for, it would first try to set the first workspace than the
transient-for window and then fallback to all/current workspace.

After that commit we only try to set the same workspace than the
transient-for window, but it gets none as neither is on a single workspace,
nor did really request to be on all workspaces.

Fixes crashes when opening transient X11 dialogs in the secondary monitor.

09bab98b1e core: Avoid consecutive workspace changes in window construction
We first set the workspace to the transient-for parent's, and then
try to set on the current workspace. If both happen, we double the
work on adding/removing it from the workspace, and everything that
happens in result.

Should reduce some activity while typing on the Epiphany address
bar, as the animation results in a number of xdg_popup being created
and destroyed to handle the animation.

ac5d9ec558 keybindings: Do not grab the locate-pointer key if unnecessary
On X11, mutter needs to keep a grab on the locate-pointer key to be able
to trigger the functionality time the corresponding key combo is
pressed.

However, doing so may have side effects on other X11 clients that would
want to have a grab on the same key.

Make sure we only actually grab the key combo for "locate-pointer" only
when the feature is actually enabled, so that having the locate pointer
feature turned off (the default) would not cause side effects on other
X11 clients that might want to use the same key for their own use.
