Add a method meta_context_destroy() that both runs dispose and unrefs
the context. Tear down is moved to dispose() so that things owned by the
context are destroyed when calling meta_context_destroy(), or when the
last reference is released.

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.

As with the compositor type enum, also have the X11 display policy enum,

Configuration is the first step of the lifetime of a context, after

Scanout doesn't go through the usual path of compositing and doing

In order to make it possible to e.g. unload an unused DRM device, we

The DRM buffers aren't really tied to mode setting, so they shouldn't

Handle open() failing due to being interrupted by trying again until it

It's only when we take/release from/to logind we need these two

This changes the way the KMS backends load; if we're headless, we always
use the dummy one and fail otherwise; in other cases, we first try the
atomic backend, and if that fails, fall back on the simple one.
The aim for this is to have the impl device open and close the device
when needed, using the device pool directly.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1828>
This practically does the same thing as part of MetaLauncher, except
with added thread safety and caching. For example, opening the same file
a second time will return the same MetaDeviceFile, and only once all
acquired MetaDeviceFile's are released, will the file descriptor be
closed and control of the device released.

When the MetaWindow resize machinery for toplevels ended up in the
Wayland window implementation, we tried to avoid configuring
not-yet-mapped windows that just had its zero sized dimension pass
through the constraint machinery, resulting in a 1x1 sized window.
If we'd properly set up the min size metadata earlier, that 1x1 would
likely be the minimum size set of a window, which makes things harder to
predict when peeking at side effects.
However, what the side effect peeking intends to do, as documented in
the comment, was to figure out when the client hadn't committed any
buffer yet, i.e. during the initial map, and in those cases avoid
sending that nasty 1x1 size, resulting in silly window sizes. A more
robust way to detect this is instead checking when we shouldn't really
try resize things our own way, and in those cases early out as was done
before.
This means that, for a yet to me mapped window, we only ever want to
send an initial non-zero configuration when 1) it's initially maximized,
2) initially fullscreen, or 3) initially tiled in any way, as those are
the situations where the compositor is the one deciding the size.

When drmModePageFlip() or drmModeAtomicCommit() unexpectedly failed (e.g.
ENOSPC, which has been seen in the wild), this failure was not handled
very gracefully. The page flip listener for the scanout was left in the
MetaKmsUpdate, meaning when the primary plane composition was later page
flipped, two page flip listeners were added, one for the primary plane,
and one for the scanout. This caused the 'page-flipped' event to be
handled twice, the second time being fatal.
Handle this by making 'no-discard' listener flag be somewhat reversed,
and say 'drop-on-error', and then drop all 'drop-on-error' listeners
when a MetaKmsUpdate failed to be processed.
Also for a "preserve" flagged update, don't ever trigger "discard"
callbacks just yet, as preserved updates are used again for the primary
plane composition, in order to not miss e.g. CRTC gamma updates, or
cursor plane updates, which were added separately.

Getting crossing events is necessary between client surfaces while

A view is only a 'CoglOnscreen' if it ends up on a CRTC, thus needs a

The mutter tests require to run in a valid environment where a display
is available and a session bus, however currently we rely on the current
environment, and this may lead to unexpected behaviors.
So let's just ensure that a display is running through xvfb-run and
that a session bus is running in a temporary directory.
We also ensure to use the gsettings memory backend, even because by
setting TestEnvironment we ensure that no other env variable is leaked
to the test.

When running multiple tests at once (with --all) as in the
installed-tests cases, we may open and close the display multiple times,
this leads to setting the alarm filter each time that the x11 display is
opened (causing a critical error) because we never disconnect from the
::x11-display-opened signal.
So disconnect from the signal on test destruction, to avoid this to be
emitted multiple times.

We first initialized the Wayland infrastructure, then the display, but
on shutdown, we first teared down the Wayland infrastructure, then the

Make things a bit more symmetric and tear down the display before
Wayland. This however means we need to tear down some things Wayland a
bit earlier than the rest. For now this is a separate function, but
eventually, it can be replaced with a signal shared by the backend's

Commit 64c9c9c5b0 fixed monitor
screencasting, when fractional screencasting is enabled.
For the remote desktop usage, NotifyPointerMotionAbsolute() submits
the new mouse pointer position in addition to the stream, where the
mouse pointer was moved.
When not using fractional scaling, the mouse pointer position is
correct.
With the usage of fractional scaling, the mouse pointer position is
wrong, as the scale of the position is applied two times.
Fix this behaviour, by reverting the second scale by dividing by the
logical monitor scale, when fractional scaling is used.

Some clients such as mpv might set the WM_TITLE as a UTF8_STRING based

for things like the overview or the window switcher where it would
trigger an UTF8 validation error and leave the shell in an unusable

All pointer a11y is a fabrication of Clutter backend-independent
code, with the help of a ClutterVirtualInputDevice and with some
UI on top.
On the other hand, MetaInputSettings is a backend implementation
detail, this has 2 gotchas:
- In the native backend, the MetaInputSettings (and pointer a11y
with it) are initialized early, before the ClutterSeat core
pointer is set up.
- Doing this from the MetaInputSettings also means another dubious
access from the input thread into main thread territory.
Move the pointer a11y into ClutterSettings, making this effectively
backend-independent business, invariably done from the main thread

Compositor behaviour when calling `wl_data_device_manager_get_data_device`
for the same seat multiple times is not very clearly defined in
the spec and both Mutter and Weston currently don't handle
the DnD case properly.
While Weston handles DnD only for the last created data device,
Mutter, because of some internal reshuffling, ends up toggling
between two devices.
Properly handling this case requires some bigger changes. So
in order to behave predictable and in line with Weston,
only take the last created data device into account while
still keeping the previous created ones around.
The main affect client here is Firefox, which gets very
confused by the toggling behaviour and becomes more stable

Virtual Kernel Mode Setting (vkms) is a virtual /dev/dri/card* device
not backed by any actual hardware. It's intended for testing purposes,
e.g. to run tests suites with a reproducable setup, or in continuous
integration pipelines.
Currently mutter don't have any tests that can run on top of vkms, but
will eventually get that. To prepare for the ability to do that, and
having said kernel module loaded without causing wierd issues with any
active session, add an udev rule that tells mutter to ignore any vkms
device.
Otherwise, when vkms is loaded, mutter would detect it, assume it's a
regular monitor, configure it as such, thus add a region of the stage
that ends up nowhere, which isn't very helpful. It might also conflict
with running actual tests that need to interact with vkms if the active
session has taken control of it.

When GNOME is animating a display fade when the night light feature is toggled
on or off, it sends a lot of change requests for the CTM property in the
process, which triggers a lot of display probes from gdk. In the case of the
night light feature, the CTM itself is not actually changing, so these requests
are redundant. Fix this by caching the CTM value in the MetaOutputXrandr and
skipping the server requests if it's not being changed.

When we set the matrix, we checked the device mapping mode in the main
thread, then passed along the calculated matrix to the input thread for
application. This could however be racy, as the mapping mode is managed
in the input thread. Fix this by sending the unaltered matrix, having
the input thread checking the mapping mode.

The connector state wasn't properly predicted, as it earlied out if
the connector wasn't part of a mode set connector list.
Instead use the old CRTC to check whether it was used in any mode set,
and whether the connector was part of any new mode set, to predict
whether the connector is inactive or active.

When a device only had mode sets which turned off monitors, not enabling
anything, there would be no KMS update created and posted, and the
active monitors would remain on.

On hybrid graphics system, the primary path used to transfer the stage
framebuffer onto the dedicated GPU's video memory preparing for scanout,
is using the dedicated GPU to glBlitFramebuffer() the content from the
iGPU texture onto the scanout buffer.
After we have done this, we reset the current EGL context back to the
one managed by cogl. What we failed to do, however, was to reset the
current EGL context when we inhibited the actual page flip due to having
entered power save mode.
When we later started to paint again, Cogl thought the current EGL
context was still the correct one, but in fact it was the one used for
the iGPU -> dGPU blit, causing various EGL surface errors, and as a side
effect, eventually hitting an assert.
Fix this by making sure we reset to the Cogl managed EGL context also
for this case.
