Instead of telling MetaKmsConnector fill a MetaKmsUpdate with connector
property changes, make the update itself aware of the changes, making
the impl side translate that to property changes.

Instead of having MetaKmsPlaneAssignment carry a low level property

With the aim at always using the property table to fetch and parse

Values may need to be processed and parsed in custom ways; make this

Instead of relatively verbosely going through the DRM properties finding
the properties we care about and saving their ID's, add a more
declarative way to fetch property metadata. This'll allow for fetching
more property IDs with relatively less code, which will be useful for
the atomic backend.

This contains a copy of a drmModeModeInfo, describing a mode. It also
has an unused pointer to the impl device it is associated with. It'll
later be used to get a blob ID for the mode.

Current Xwayland has marked the command line option "-listen" as
deprecated in favor of "-listenfd".
Use the pkg-config variable "have_listenfd" (if available) from Xwayland
to determine if we should use that option, to avoid a deprecation
warning when spawning Xwayland.

Mutter listens to two display connections, one for regular X11 clients
and another one for the so called "managed services".
Once an available display number is found for the regular X11 clients,
mutter would then redo the work to find another available display number
for the managed services.
Yet, it does so starting from the same initial display, which is a waste
of time since it just tried all displays to find the first available
one, so all these, including the regular display it just took, are now
in use.
So instead of starting over from the beginning when looking for a
display available for the managed services, continue from the next
display immediately after the one we found precedently.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1680>
Some X11 servers may not always create a lock file, yet mutter uses the
lock file to find a possible display number and then tries to bind to
the socket corresponding to that display number.
If it fails to bind, it will simply bail out. As a result, if an X11
server is already listening on that display but hadn't created a lock
file, mutter won't be able to start Xwayland.
To avoid that possible issue, make mutter retry with another display
for a given number of tries when binding fails even though the display
was supposed to be available based on the lock file presence.

The function choose_xdisplay() calls open_display_sockets() which calls
ensure_x11_unix_dir().
We don't need to do that from within the loop though, as the directory
/tmp/.X11-unix is the same regardless of the display number.
Move the call to ensure_x11_unix_dir() from open_display_sockets() to
choose_xdisplay() prior to enter the display loop.

In case of failure to open the display sockets, we would not propagatre
the error which can cause a crash when trying to show the error message.
Properly propagate the error to avoid the crash.

In the shutdown paths we check with the X11 display whether there's
remaining clients. However this happens in paths that happen after
the MetaX11Display vanished in the case of Xwayland crash.
Since in that situation the clients are forcibly vanishing too,
skip the client check.

This means backend implementations can have more control of the order of
how things are destroyed. To be precise, this will, in the next commit,
allow us to destroy the logind integration after the clutter backend
thus the libinput owning seat, that uses the logind integration to
release input devices.

We can't post tasks to the input thread when cleaning up the
MetaSeatImpl, as that will make the GTask complain about adding
references to a to be purged object. Avoid this by adding an explicit
meta_seat_impl_destroy() function that handles the destruction of the
MetaSeatImpl properly.
This also does more of the cleanup in the input thread, as that is where
it was managed. Will likely not make a difference as before this
happened after tearing down the thread, but lets tear down things in the
thread they were managed for good measure.
This fixes the last log spew I see right now when terminating mutter.

Closing automatically Xwayland once all relevant X11 clients are gone is
inherently racy, if a new client comes along right at the time we're
killing Xwayland.
Fixing the possible race conditions between mutter, Xwayland and the X11
clients may take some time.
Meanwhile, make that an experimental feature "autoclose-xwayland".

<super> is considered a system modifier, and applications cannot use it
for keyboard shortcuts or as button modifier. It doesn't seem too much
of a loss taking <super>+scroll-event away as well, so that it becomes
available to gnome-shell/extensions.

Currently, mutter checks for the presence of X11 windows to decide
whether or not Xwayland can be terminated, when Xwayland is started on
demand.
Unfortunately, not all X11 clients will map a window all the time, an
X11 client may keep the X11 connection opened after closing all its
windows. In that case, we may terminate Xwayland while there are some
X11 client connected still, and terminating Xwayland will also kill
those X11 clients.
To avoid that issue, check the X11 clients actually connected using the
XRes extension. The XRes extension provides the PID of the (local) X11
clients connected to the Xserver, so we need to match that against the
actual executable names, and compare with a list of known executables
that we can safely ignore, such as ibus-x11 or gsd-xsettings.
We also check against our own executable name, considering that the X11
window manager is also an X11 client connected to the Xserver.
Also, XRes returning the PID of local clients only is not a problem
considering that Xwayland does not listen to remote connections.
However, if the user spawns a client remotely on another system using
ssh tunneling (ssh -X), only clients which actually map a window will
be accounted for.

Changes in games between fullscreen and windowed modes may trigger
chaotic situations where the buffer and the frame size temporarily
disagree, producing rectangles with negative width/height. This is
usually followed by other updates that bring the pointer constraint
up to date.
This makes cairo panic and return an "error" empty region, which breaks
deeper down when using the region rectangles to apply the pointer
constraint.
If we hit this situation, ignore the frame rectangle, and just go with
the buffer rectangle.

We didn't tear down the libinput objects in the right thread when
exiting, but did so after the input thread exited.
We also tried to destroy the libinput devices after the libinput context
was destroyed, which isn't allowed.
Fix these two issues by tearing down the libinput objects in a input
thread task that when done exits the input thread. This effectively
"flushes" the input thread tasks while destroying the libinput objects
just before the thread exits.
While it might fine to tear down libinput objects in an arbitrary (main
in this case) thread while making sure nothing pokes at it in parallel
(e.g. the input thread is gone), libinput is by definition single
threaded, and could theoretically make assumptions about this, and we
shouldn't cause any possible surprises here, so make sure to destroy it
all in the right thread.
This fixes an abort() on exit caused by an assert about invalid object
destruction in libinput.

The "seat" usually refers to the ClutterSeat (MetaSeatNative) object,

When supported, this property allows the window system to apply a 3x3 color
correction matrix in order to transform colors from the window system's native
color space to the measured color space of a display device.
Query for this property and set the 'supports-color-transform' property in the
GetResource reply. Add support for the SetOutputCTM DBus method and plumb that
through to the server's CTM property.

Currently, the NotifyPointerAxis method always assumes that the scroll
source is CLUTTER_SCROLL_SOURCE_FINGER.
This is however not always true and in some cases a remote desktop
client needs to submit a PointerAxis event with a custom axis step.
This is for example the case with high resolution mouse wheels, where
the NotifyPointerAxisDiscrete method is unsuitable.
In such cases NotifyPointerAxis needs to be called, but with the
intention that the scroll source is still a mouse wheel.
To solve this situation, don't assume the scroll source always to be
CLUTTER_SCROLL_SOURCE_FINGER.
Instead, add further flag options to NotifyPointerAxis, which allow a
remote desktop client to choose the scroll source.
This way a remote desktop client can choose what scroll source is the
most suitable one for the current scroll event.

The monitor texture is the final background image. It doesn't need to

Unfortunately there's situations where we can't fully rely on only
crossing events here. One such situation is pointer visibility changes
due to touch interaction, or e.g. after closing the lid.
In these situations the pointer position stays the same, picks the
same actor, yet we want to see the right surface as the pointer focus
again in the wayland side.
This used to happen on the first motion event after the pointer
visibility change before commit ad3f2b0b86, use motion events again
for picking so we don't break these usecases.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1657>
These events may be emitted for touchpoints (in which case they contain
an event sequence). Ignore those as they are not relevant for pointer
picking, and shouldn't influence its focus.

This signal may be left dangling when disconnecting a device, and be executed
later on if the device is connected again, and mapped to other output. Make it

Just because of implementation details, this is only relevant to Wayland,
and is done via ::effects-completed handlers there. Ideally, Clutter should
notice by itself about effects starting, finishing, and affecting picking.
Doing this in generic code seems slightly cleaner in the interim.
