Currently the EGLDevice code gets the display and calls eglInitialize.
As a follow-up it checks the required EGL extensions - technically it
could check the EGL device extensions earlier.
In either case, eglTerminate is missing. Thus the connection to the
display was still bound.
This was highlighted with Mesa commit d6edccee8da ("egl: add
EGL_platform_device support") + amdgpu.
In that case, since the eglTerminate is missing, we end up reusing the
underlying amdgpu_device due to some caching in libdrm_amdgpu. The
latter in itself being a good solution since it allows buffer sharing
across primary and render node of the same device.
Note: we should really get this in branches all the way back to 3.30.

When stage views are scaled with fractional scales, the cursor rectangle
won't be aligned with the physical pixel grid, making it potentially
blurry when positioned in between physical pixels. This can be avoided
by aligning the drawn rectangle to the physical pixel grid of the stage
view the cursor is located on.

Attaching a NULL buffer should hide the cursor sprite. In these cases,
we we'll have neither surface nor buffer damage, so also update when we
just attached a NULL buffer.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/630
When 252e64a0ea moved the texture
ownership to MetaWaylandSurface, it failed to handle the case when a
NULL-buffer is attached, leaving the texture reference in place. This
caused issues when the surface should have been hidden (e.g. attaching a
NULL buffer to a cursor surface for hiding the cursor sprite).

Starting from commit 7713006f5, during X11 disposition we also unmanage the
windows using the xids hash table values list.
However, this is also populated by the X11 Meta barrier implementation and then
contains both Windows and Barriers.
So when going through the values list, check whether we're handling a window or
a barrier and based on that, unmanage or destroy it.

As per commit 7718e67f, destroying the compositor causes destroying window
actors and this leads to stack changes, but at this point the stack was already
disposed and cleared.
So, clear the stack when any component that could use it (compositor, and X11)
has already been destroyed.
As consequence, also the stamps should be destroyed at later point.

To emulate X11 grabs, mutter as a Wayland compositor would disable its
own keyboard shortcuts and when the X11 window is an override redirect
window (which never receives focus), it also forces keyboard focus onto
that X11 O-R window so that all keyboard events are routed to the
window, just like an X11 server would.
But that's a bit of a “all-or-nothing” approach which prevents
applications that would legitimately grab the keyboard under X11 (like
virtual machine viewers) to work by default.
Change “xwayland-allow-grabs” to control whether the keyboard focus
should be locked onto override redirect windows in case of an X11 grab.
For stringent needs, careful users can still use the blacklisting
feature (i.e. a list containing “!*”) to prevent grabs from any X11
applications to affect other Wayland native applications.

Having a cursor role with a NULL renderer is valid state, and even desirable

We're currently emitting the 'grab-op-end' signal when the grab prerequisites
are met, but when display->grab_op is still set to a not-NONE value and thus
meta_display_get_grab_op() would return that in the signal callback.
And more importantly when this is emitted, devices are still grabbed.
Instead, emit this signal as soon as we've unset all the grab properties and
released the devices.

We handle this in backend specific code for x11, so do the wayland
bits here. We can only honor this on applications that request focus
on a surface after a startup request, as we do need an explicit
surface to apply the workspace on (and we don't have additional clues
like WMCLASS on X11). Notably, gtk_shell1.notify_startup doesn't suffice.
Another gotcha is that the .request_focus happens when the surface is
already "mapped". Due to the way x11 and the GDK api currently work (first
reply on the startup id, then map a window, then request focus on that
window). This means the surface will ignore at this point
window->initial_workspace, so it must be actively changed.

On a successful DnD operation we may expect the wl_data_source and
wl_data_offer to live long enough to finish the data transfer, despite the
grab operation (and other supporting data) being gone.
When that happens, the compositor expects a wl_data_offer.finish request to
notify that it finished. However the client may still chose not to send that
and destroy the wl_data_offer instead, resulting in the MetaSelectionSource
owner for the DnD selection not being unset.
When that happens, the DnD MetaSelectionSource still exists but it's
detached from any grab operation, so will not be unset if eg. the drag
source client destroys the wl_data_source. This may result in crashes when
the next drag operation tries to replace the owner DnD MetaSelectionSource.
Check explicitly for this case, in order to ensure the DnD owner is unset
after such operations.

This argument instructs Xwayland to exit when there are no further
client connections. However we eventually want to handle restarts
ourselves (where, notably, mutter's will be at least the last client
connection).
This behavior could also induce race conditions on startup with clients
that quickly open and close a display, which is a more pressing issue.
Also, add -noreset back (which was also removed in commit 054c25f693 that
added -terminate). We don't want to reset the X server to a pristine state
in that situation either.

Code underneath seems to handle errors properly, or be x11-agnostic

It is now separated into meta_xwayland_start(), which picks an unused
display and sets up the sockets, and meta_xwayland_init_xserver(), which
does the actual exec of Xwayland and MetaX11Display initialization.
This differentiation will be useful when Mutter is able to launch Xwayland
lazily, currently the former calls into the latter.

In all places (including src/wayland) we tap into meta_x11_display* focus
API, which then calls meta_display* API. This relation is backwards, so
rework input focus management so it's the other way around.
We now have high-level meta_display_(un)set_input_focus functions, which
perform the backend-independent maintenance, and calls into the X11
functions where relevant. These functions are what callers should use.

We use a GtkIconTheme (thus icon-theme, thus xsettings, thus x11) just to
grab a "missing icon" icon to show in place. Relax this requirement that
surfaces for icon/mini-icon will be set, and just let it have NULL here.
It seems better to have the callers (presumably UI layers) aware of this
and set a proper icon by themselves, but AFAICS there is none in sight,
not even plain mutter seems to use MetaWindow::[mini-]icon. Probably
worth a future cleanup.

If the check happens on --nested (X11 backend) while there is no X11

This explicit ungrab is made to ensure the other X11 display connection
is able to start an active grab immediately on the device without receiving
AlreadyGrabbed.
This is just relevant if there's two X11 display connections to transfer

This object takes care of the X11 representation of the window stack,
namely the _NET_CLIENT_LIST and _NET_CLIENT_LIST_STACKING root window
properties.
This code has been lifted from src/core/stack.c into src/x11 as it's
dependent on the X11 display availability. This also leaves MetaStack
squeaky clean of x11 specifics.

We'd break the loop for moving attached windows at the first window,
meaning we'd only ever move a single attached dialogs or popup if it was
the first window in the list. This doesn't work out well when there are
multiple popups open, so don't break out of the loop at all until all
windows are potentially moved.
This fixes an issue in gtk4 where one or more non-grabbing popups would
end up unattached if there were more than one and the parent window was
moved.

XkbNewKeyboardNotify informs the client that there is a new keyboard
driving the VCK. It is essentially meant to notify that the keyboard
possibly has a different range of HW keycodes and/or a different
geometry.
But the translation of those keycodes remain the same, and we don't
do range checks or geometry checks (beyond using KEY_GRAVE as "key
under Esc", but that is hardly one). It seems we can avoid the
busywork that is releasing all our passive grabs, reloading the keymap
and regenerating the keycombos and restoring the passive grabs.

There is no reason why we should have an internal type enum when we have

All child classes of `MetaWaylandShellSurface` as well as
`MetaWaylandSurfaceRoleXWayland` should only sync their actor if
their toplevel surface has a window. Currently this check is done
in the actor-surface class, but not all surface classes have a
toplevel window, e.g. dnd-surfaces.
Move the check to the right places.
For subsurfaces this assumes that the subsurface is not the child of
a window-less surface (like, as stated above, e.g. a dnd-surface).
If we want to support subsurfaces of window-less surfaces in the future
we have to extend the check here.
But as this is not a regression, ignore this case for now.

If we update the ready time while the source is already in the

This is a simple clipboard manager implementation on top of MetaSelection.
It will inspect the clipboard content for UTF-8 text and image data whenever
any other selection source claims ownership, and claim it for itself
whenever the clipboard goes unowned.
The stored text has a maximum size of 4MB and images 200MB, to prevent the
compositor from allocating indefinite amounts of memory.
