It's still used by e.g. GNOME Shell to produce fallback icons for X11
applications that doesn't come with a .desktop file. Geometry stays in
the generic class because it's used for minimize animations and is
configured by the panel (e.g. the one in gnome-shell-extensions).

The comments in this function tells a story of C programmer self
reflecting about data types and Perl. While that can be nice, the rest
consisted mostly of repeating what the code line below did, with the end
result being that the function didn't fit on screen, resulting in worse
readability overall.

There may be situations where we may stack a ClutterGrab on top of a
wayland popup's. Since ClutterGrab should win over client grabs, we
mostly correctly figure out that it should start doing
bypass_wayland=TRUE and bypass_clutter=FALSE while the ClutterGrab
holds, however the late checks for the MetaDisplay event route can
still toggle bypass_clutter on, resulting in neither handling events.
This check for wayland popups in the display event route should just
enforce wayland handling if wayland is meant to be receiving events,
so ensure these don't mix together.

Wayland event processing and WM operations are themselves outside the
ClutterGrab loop so far. Until this is sorted out, these pieces of
event handling have got to learn to stay aside while there is a
ClutterGrab going on.
So, synchronize foci and other state when grabs come in or out, and
make it sure that Wayland event processing does not happen while
grabs happen.

When privacy screen is changed and this happens on explicit user request
(that is not a setting change) we should notify about this via an OSD.
To perform this, we keep track of the reason that lead to a privacy
screen change, and when we record it we try to notify the user about.
When the hardware has not an explicit hotkey signal but we record a
change we must still fallback to this case.

There will be another mode added later, 'test'; prepare for this by
changing the existing "mode" boolean ('headless') to a mode, which is
either 'default' or 'headless'. Checking the is_headless variable is
changed to using the function is_headless(), except for one place, being
VT switching, which in preparation is only allowed on the 'default'
mode. Other places where it makes sense, the conditions are changed to
switch statements.

We save the window rect before going fullscreen to a dedicated variable,
so we can go back to the correct dimension. We also have a dedicated
variable for returning from other window states, e.g. maximized, and
this one we initialized when creating the MetaWindow. This meant that we
could always rely on this being up to date on X11 windows that were
mapped maximized or fullscreen.
What the commit that introduced the saved rect dedicated for going
unfullscreen missed was to initialize the new saved rectangle too when
creating the MetaWindow. This resulted in windows mapped as fullscreen
often ending up misbehaving when unfullscreening, as mutter would tell
them to unfullscreen to 0x0.

Since this signal is in a hot path during input handling, it makes sense
not to have this be a signal at all, currently most of the time spent in
it is in GLib signal machinery itself.
Replace it with a function/user data pair that are set on the sprite
itself. Only the places that create an sprite are interested in hooking
one ::prepare-at behavior per sprite, so we can do with a single pair.
This makes meta_cursor_sprite_prepare_at() inexpensive enough.

Change some things in these "app is alive" checks:
- The dialog timeout is separated from the ping timeout, in order
to show it again at a constant rate after dismissing, despite in
flight pings. It still shows immediately after the first failed
ping.
- As we want to tap further into is-alive logic, MetaWindow now
made it a property, that other places in code can fetch and
subscribe.
- Motion events trigger ping (as long as there was none other in
flight for the same window), and are counted between ping and
pong, in order to preemptively declare the window as not alive
before there is trouble with event queues being overflown.
This results in a separate logic between "the application does
not respond" and "we are showing the close dialog" so that the
former may get triggered independently.

Currently the stored unconstrained_rect is only ever updated if there
was a move, resize or state change according to the move_resize_internal
implementation. For Wayland windows however resizes or state changes
are done in two steps, first the new configuration is sent to the client
and then once client acknowledges it, it is set on the mutter side in
another move_resize_internal call. Only the second call would result in
the unconstrained_rect being updated.
This started causing problems when unfullscreening windows was
immediately followed by a strut change. These strut changes started
happening in gnome-shell due to the visibility of the panel now being
considered for the struts and the presence of a fullscreen causing it to
be hidden until unfullscreen. In this situation first the unfullscreen
would resize the window to its pre-fullscreen size as expected, but then
the strut change triggers another window resize. This window resize is
based on the stored unconstrained_rect, which is still at the fullscreen
size because the unfullscreen resize only has sent its configuration,
but it has not been acknowledged yet. As a result the strut change
causes a resize to the fullscreen size which due to the constraints now
looks like a maximized window.
To fix this always update the unconstrained_rect when the requested size
has changed, but not when a previous request has been acknowledged
unless it is originating from the client itself.
If this included the move_resize_internal call from acknowledging the
size as well, it would be possible for this to be delayed long enough on
the client side to overwrite an intermediate resize originating from
mutter. And if this did not include resizes originating from the client,
clients would not be able to set an initial window size.

meta_window_wayland_finish_move_resize() is called for both, finishing
a resize that has been requested through/by mutter and for resizes
directly done by the client. This introduces a CLIENT_RESIZE flag to
differentiate the former from the latter. Having this distinction is
required to know what the last requested size by either the client or
mutter is while ignoring older requests that might only have been
applied now.
This excludes client resizes when there are still pending
configurations, because the resize is known to be only temporary.

We setup Xwayland in an early phase of the X11 display, before we had a
MetaX11Display, and teared down in a couple of places happening when
tearing down the Xwayland integration if the X server died or
terminated. It was a bit hard to follow what happened and when it
happened. Attempt to clean this up a bit, with things being structured
as follows:
* Early during X11 display connection setup, only setup the rudimentary
X11 hooks, being the libX11 error callbacks, and adding the local
user to XHost.
* Move "initialize Xwayland component" code to a new
'x11-display-setup' signal handler. Things setup here are cleaned up
in the 'x11-display-closing' handler.
* Connect to 'x11-display-setup' and 'x11-display-closing' up front,
and stay connected to these two.

If the ancestor a window is transient for has already been unmanaged
when the window is activated via meta_window_activate_full while its
transient_for property still points to that ancestor, this will cause
the already unmanaged ancestor to get added to the windows workspace.
This is after the ancestor had its workspace set to NULL when it was
unmanaged, causing this to look like an actual workspace change. Once
the window has been added to the workspace, it will never be removed
again, because the it has already been unmanaged. This confuses things
like the shell window tracker and leads to phantom windows being
considered present for apps that are not even running anymore.
