The end goal is to have all clutter backend code in src/backends. Input
is the larger chunk of it, which is now part of our specific
MutterClutterBackendX11, this extends to device manager, input devices,
tools and keymap.
This was supposed to be nice and incremental, but there's no sane way
to cut this through. As a result of the refactor, a number of private
Clutter functions are now exported for external backends to be possible.

After the introduction of locate-pointer (commit 851b7d063 -
“keybindings: Trigger locate-pointer on key modifier”), inhibiting
shortcuts would no longer forward the overlay key to the client.
Restore the code that was inadvertently removed so that inhibiting
shortcuts works on the overlay key again.

Geometry scale is applied to each surface individually, using
Clutter scales, and not only this breaks subsurfaces, it also
pollutes the toolkit and makes the actor tree slightly too
fragile. If GNOME Shell mistakenly tries to set the actor scale
of any of these surfaces, for example, various artifacts might
happen.
Move geometry scale handling to MetaWindowActor. It is applied
as a child transform operation, so that the Clutter-managed
scale properties are left untouched.
In the future where the entirety of the window is managed by a
ClutterContent itself, the geometry scale will be applied
directly into the transform matrix of MetaWindowActor. However,
doing that now would break the various ClutterClones used by
GNOME Shell, so the child transform is an acceptable compromise
during this transition.

meta_shaped_texture_update_area() is a private function that
is exposed in the public headers. It is not used anywhere
outside Mutter, and should really be in the private header.
Move it to the private header.

Now that MetaShapedTexture is not a ClutterActor anymore, it does
not make sense to make it a MetaCullable semi-implementation. This
is, naturally, a responsibility of MetaSurfaceActor, since now
MetaShapedTexture is a ClutterContent and as such, it only cares
about what to draw.
Move the MetaCullable implementation of MetaShapedTexture to
MetaSurfaceActor.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/409
By implementing ClutterContent, it is expected that
MetaShapedTexture can draw on any actor. However,
right now this is not possible, since it assumes
that the drawing coordinates and sizes of the actor
are synchronized with its own reported width and
height.
It mistakenly draws, for example, when setting an
actor's content to it. There is no way to trigger
this wrong behavior right now, but it will become
a problem in the future where we can collect the
paint nodes of MetaShapedTexture as part of other
ClutterContent implementations.
Use the allocation box passed by the actor to draw
the pipelines of MetaShapedTexture.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/409
Now that MetaShapedTexture is a ClutterContent implemetation that
is aware of its own buffer scale, it is possible to simplify the
event translation routines.
Set the geometry scale in MetaSurfaceActor, and stop adjusting the
surface scale when translating points. Also remove the now obsoleted
meta_wayland_actor_surface_calculate_scale() function.

MetaWindowActor is the compositor-side representative of a
MetaWindow. Specifically it represents the geometry of the
window under Clutter scene graph. MetaWindowActors are backed
by MetaSurfaceActors, that represent the windowing system's
surfaces themselves. Naturally, these surfaces have textures
with the pixel content of the clients associated with them.
These textures are represented by MetaShapedTexture.
MetaShapedTextures are currently implemented as ClutterActor
subclasses that override the paint function to paint the
textures it holds.
Conceptually, however, Clutter has an abstraction layer for
contents of actors: ClutterContent. Which MetaShapedTexture
fits nicely, in fact.
Make MetaShapedTexture a ClutterContent implementation. This
forces a few changes in the stack:
* MetaShapedTexture now handles buffer scale.
* We now paint into ClutterPaintNode instead of the direct
framebuffer.
* Various pieces of Wayland code now use MetaSurfaceActor
instead of MetaShapedTexture.
* MetaSurfaceActorWayland doesn't override size negotiation
vfuncs anymore

With the addition of xauth support (commit a8984a81c), Xwayland would
rely only on the provided cookies for authentication.
As a result, running an Xclient from another VT (hence without the
XAUTHORITY environment variable set) would result in an access denied.
The same on X11 is granted because the local user is automatically
granted access to Xserver by the startup scripts.
Add the local user to xhost at startup on Xwayland so that the user can
still run a client by setting the DISPLAY as long as it's the same user
on the same host.

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.

Introduce MetaCompositorX11, dealing with being a X11 compositor, and
MetaCompositorServer, being a compositor while also being the display
server itself, e.g. a Wayland display server.

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.

Add meta-kms and meta-monitor-manager-kms listener for the udev
device-removed signal and on this signal update the device state /
re-enumerate the monitors, so that the monitors properly get updated
to disconnected state on GPU removal.
We really should also have meta-backend-native remove the GPU itself
from our list of GPU objects. But that is more involved, see:
https://gitlab.gnome.org/GNOME/mutter/issues/710
This commit at least gets us to a point where we properly update the
list of monitors when a GPU gets unplugged; and where we no longer
crash the first time the user changes the monitor configuration after
a GPU was unplugged.
Specifically before this commit we would hit the first g_error () in
meta_renderer_native_create_view () as soon as some monitor
(re)configuration is done after a GPU was unplugged.

drmModeGetConnector may fail and return NULL, this may happen when
a connector is removed underneath us (which can happen with e.g.
DP MST or GPU hot unplug).
Deal with this by skipping the connector when enumerating and by
assuming it is disconnected when checking its connection state.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/713
drmModeGetCrtc may fail and return NULL. This will trigger when
meta_kms_crtc_update_state gets called from meta_kms_update_states_sync
after a GPU has been unplugged leading to a NULL pointer deref causing
a crash.
This commit fixes this by checking for NULL and clearing the current_state
when NULL is returned.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/713
Before this commit meta_kms_crtc_read_state was overwriting the
entire MetaKmsCrtcState struct stored in crtc->current_state including
the gamma (sub)struct.
This effectively zero-s the gamma struct each time before calling
read_gamma_state, setting the pointers where the previous gamma values
were stored to NULL without freeing the memory. Luckily this zero-ing
also sets gamma.size to 0, causing read_gamma_state to re-alloc the
arrays on each meta_kms_crtc_update_state call. But this does mean that
were leaking the old gamma arrays on each meta_kms_crtc_update_state call.
This commit fixes this by making meta_kms_crtc_read_state only overwrite
the other values in the MetaKmsCrtcState struct and leaving the gamma
sub-struct alone, this will make read_gamma_state correctly re-use the
gamma tables if the gamma table size is unchanged; or re-alloc them
(freeing the old ones) if the size has changed, fixing the memory leak.

The "device-added" signal should use g_cclosure_marshal_VOID__OBJECT not
g_cclosure_marshal_VOID__VOID.
Instead of fixing this manually, simply replace the closure function for
both signals with NULL, glib will then automatically set the correct
va_marshaller.

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".
https://gitlab.gnome.org/GNOME/mutter/merge_requests/728
There may be cases where a X11 client does not spawn any X11 windows (eg.
simple clients like xinput --list, or xlsclients), in this case the Xwayland
server would remain running until X11 windows happen to come and go in the
future.
Firing the shutdown timeout on restart caters for this, and would be undone
if the client maps X11 windows.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/728
Where the prepare_auth_file() call is, it does create a new one on every
respawn of Xwayland. This is not benefitial, as the XAUTHORITY envvar is
already fixed in the session.
Only create the XAuthority file once, and reuse it on future Xwayland
respawns.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/728
When primary_offer_receive checks if the requested mime_type is supported,
it should check against the list of mime-types supported by the
primary-selection, instead of the list for the clipboard.
This fixes primary selection copy paste from X11 apps to Wayland apps
not working.

Explicitly checking the dimensions of a mode to determine whether it
should be advertised or not fails for portrait style modes. Avoid this
by checking the area instead.

We only listen for those so we know there's no more X11 clients that we
should keep the Xwayland server alive for. Check first that we really did
request Xwayland to be handled on demand for this, otherwise the check is
superfluous, even harmful.
https://gitlab.gnome.org/GNOME/mutter/issues/719
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.

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.
