Until recently, mutter-test-runner called into libraries that
indirectly depend on (mutter's fork of) Clutter, but did not actually
call into Clutter itself. Commit 1bf70334 "tests/runner: Make test
runner use the headless backend" gave it a direct call into Clutter,
which means the runtime linker will fail unless the executable's
RUNPATH is sufficient to find Clutter.
For future-proofing, do the same for the other test executables.

This adds the 4 new connector types that mutter didn't know about from
drm_mode.h in the kernel.
Noticed because mutter kept crashing when plugging in a USB-C adapter to
use an external monitor.

When we e.g. generate switch configs (i.e. the ones from pressing the
Super+P or the switch-config key on laptops), try a bit harder to find a
"good" monitor scale.
With "good", it means pick a scale that was used in a previous
configuration. In practice, this means that if you for example have
configured your external monitor to use a specific scale, then pressed
e.g. "built in only", and then switched back to e.g. "external only" or
"linear", the generated configuration will use the scale that was
previously configured.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2479>
If two modes are roughly the same, they should probably use the same UI
scaling factor. I.e. for the same monitor, if a 4K mode was configured to
have a certain scaling factor, and we generate a new configuration with
a similar sized 4K mode, we should re-use the scale previously
configured; however if we e.g. go from a 4K mode to a FHD mode, we
shouldn't.
This allows implementing better hueristics when using the switch-config
feature, where we'd be less likely to loose the for a certain monitor
mode combination previously configured scaling factor.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2479>
This will eventually help with better hueristics for finding a good
scale. It currently doesn't change much, but the helper will later gain
more functionality that will also help when coming up with mirroring
configs.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2479>
The resulting logical monitor was eventually marked as primary anyway,
but without the config being marked as such, various primary properties
was not set e.g. the one on the MetaOutput. Also, tests would fail.

This condition is inverted of how it should be. Since pad focus relies
on grouped devices lookups (e.g. pads not grouped with a tablet do not
focus surfaces), this fixes issues in pad focus and event propagation to

If the window didn't have a size, it would still have a monitor, and
when we are asked to update, we must update, as the old monitor might
not be kept around, leaving us vulnerable to use after free.
Avoid not updating the monitor by using the stored IDs (preferred, or
previous) to find suitable logical monitors, with the primary monitor
being the last fallback unless we're completely headless.
This fixes the assert
!window->monitor ||
g_list_find (meta_monitor_manager_get_logical_monitors (monitor_manager),
window->monitor)
in meta_window_update_for_monitors_changed() being hit when a Wayland
window has been created, but not mapped, when a hotplug happens.

This will allow tests to change monitor resolution. The first argument
is the monitor ID; there is always one monitor added by default, and it
has the id 0. It's currently not possible to add more monitors, so

This hasn't worked for a while, since the test always runs the nested

mutter needs GDK to use the x11 backend. It already calls
gdk_set_allowed_backends ("x11") for this purpose; however, if
GDK_BACKEND=wayland (or any other non-x11 backend possibly) happened to
be in the environment, GDK would fail to initialize at all. This would
result in mutter not registering as X11 window manager, and all X11
clients hanging.

The "single pixel buffer" Wayland protocol extension provides a way for
clients to create 1x1 buffers with a single color, specified by
providing the color channels (red, green and blue) as well as the
alpha channel as a 32 bit unsigned integer.
For now, this is turned into a 1x1 texture. Future potential
improvements is to hook things up to the scanout candidate logic and
turn it into a scanout capable DMA buffer.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2246>
When taking the scanout path we still want to clear the
redraw-clip from the stage-view in order to ensure we skip
frames in `handle_frame_clock_frame()` if no new redraw-clip
was recorded.
This was not done previously as the accumulated redraw-clip was
needed for the next repaint, likely under the assumption that
scheduling a scanout repeatedly would be computationally cost-free.
This assumption does not hold in a VRR world.
In order to archive both, an accumulated redraw-clip for the next
paint and frame-skipping during scanout, introduce new API to defer
and accumulate redraw-clips until the next repaint.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2480>
To Wayland clients, it doesn't matter how we configure our onscreen
buffers, since they don't necessarily have the same bandwidth issues
related to mode setting, whichis the primary reason why we disable
modifiers using the udev rule, so simply check whether importing with
modifiers will work at all and advertise modifiers if so is the case.
This might help avoid issues using legacy non-modifiers path in drivers.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2546>
We disable modifiers for two reasons: an udev rule saying so, or the
lack of a working drmModeAddFB2(). However, to the users, this is not
granular enough. While the current user, whether to enable modifiers in
MetaRendererNative, doesn't need more granularity, we want to send
modifiers to Wayland clients even if the onscreen framebuffers should
still be allocated without modifiers.
Prepare for differentiating between how Wayland DMA buffers work and how
onscreen buffer allocation work by separating the relevant device flags.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2546>
This uses MetaCompositorViewNative to find a candidate surface for
scanout and to keep track of it separately for each view, effectively
allowing each CRTC to use a different buffer for direct scanout.
There are three parts for potentially assigning a buffer for direct
scanout at the compositor level:
1. Finding a candidate surface actor on the view (if any)
2. Attempting to assign the candidate's buffer for direct scanout
3. Updating references relating to the scanout candidate as needed
The three parts were moved in their entirety from being handled by the
MetaCompositorNative to being handled by the MetaCompositorViewNative.
As part of this transition, the logic was also slightly refactored so
that each of the three parts is handled by its own helper function.
This allowed to avoid the use of "goto" statements and hopefully make
the logic easier to read and follow.
The first part mentioned above was changed in this commit to make use
of the new meta_compositor_view_get_top_window_actor () API to get the
top window actor in the view instead of the top window actor on all
views.
The second part and third parts mentioned above weren't changed other
than being done in the context of a view instead of globally.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2526>
All of the checks this function performed internally were already
done before calling it, making it a simple wrapper function without a
meaningful purpose.
Removing this function also reduces the chance of additional checks
being added to the MetaSurfaceActor after it is already chosen as a
scanout candidate.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2526>
This class is meant to hold logic specific to the native backend
in the context of a MetaCompositorView.
Its addition requires making MetaCompositorView inheritable, and an
addition of a virtual function which allows each compositor to create
its own MetaCompositorView instance.
In the case of the MetaCompositorNative, a MetaCompositorViewNative
is created. In all other cases, a MetaCompositorView is created.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2526>
First, add logic in MetaCompositorView to find topmost visible
MetaWindowActor on its view, and expose it through a new API.
Then, queue an update to find the top MetaWindowActor of each
MetaCompositorView in the following cases:
1. The MetaCompositor is in its initial state.
2. The window stack order has changed.
3. A window has changed its visibility.
4. A "stage-views-changed" signal was emitted for a MetaWindowActor.
Finally, perform the queued update in meta_compositor_before_paint (),
and assert that an update isn't queued during painting. This ensures
that the top window actor in the MetaCompositorView remains up-to-date
and available to child classes of MetaCompositor throughout the entire
paint stage.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2526>
The idea is that the state of the MetaCompositorView shall be
up-to-date only in specific scenarios, thus allowing operations
performed on it to be queued and aggregated to be handled in the
right time, and only if they are still necessary.
For example, in a following commit, the top window actor in each
view will be planned (if needed) only once before painting a frame,
rendering the top window actor in the MetaCompositorView potentially
stale in all other times.
Similarly, if a MetaCompositorView is destroyed before the beginning
of the frame, a queued operation to update its top window actor can be
discarded.
As an interface segragation measure, and as part of an attempt to
avoid the use of g_return_if_fail () to check the validity of the
MetaCompositorView's state in multiple places (which is still prone to
human error), the interfaces through which a MetaCompositorView is
made available would only ones where it's state is gurenteed to be
up-to-date.
Specifically, this commit gurentees that the state of the
MetaCompositorView would be up-to-date during the before_paint () and
after_paint () vfuncs exposed to child classes of the MetaCompositor.
The frame_in_progress variable will be used in a following commit to
guarantee that the MetaCompositorView's state is not invalidated during
this time.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2526>
MetaCompositorView is a class which contains compositor logic
specific to ClutterStageViews.
Each MetaCompositorView is "attached" to a ClutterStageView as an
opaque pointer using g_object_set_qdata_full (), and is freed when
the ClutterStageView is destroyed. This ensures that the lifetime of
the MetaCompositorView can't extend beyond the lifetime of its
ClutterStageView.
In a following commit, MetaCompositorView will be expanded to allow
keeping track of the top MetaWindowActor located on each
ClutterStageView.

Although mipmapping is still slower than not mipmapping, commit 16fa2100
simplified N synchronous draw calls per texture tower into just one. So
it's more efficient now, and four years have passed since the throttling

generally faster than it used to be. So I am happy to effectively revert
commit c9c32835.

This one does proper error reporting. Via Javascript, barriers are
constructed directly via GObject construction, which currently can't
handle error reporting, but when calling from C we can. However, if we
initialize using GInitable, and use that in our constructor method, once
gjs gains support for construction using GInitable, including the error
reporting, we'll automatically get proper error reporting to Javascript.

In the past, barries were added to the window management X11 display
instance window table, and then special cased when iterating over the
list.
Since then, barriers, which are really part of the backend, has stopped
being added to the window hash table, instead being managed by the
backend. Lets clean up the left-over special casing that is no longer
needed.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2442>
Prior to this commit, barriers were created with a MetaDisplay pointer,
despite being entities related and owned by the backend. In the X11
case, it was also not hooked up to the backend X11 connection, but the
clutter one, meaning for example that the logic was active (but dormant)
also for the Xwayland connection.
Fix this by moving X11 barrier management and event processing fully to
the backend. Also replace passing a display pointer with passing a
backend pointer. Keep the display pointer around for a release, but mark
it as deprecated.

It papered over wrong `meta_rectangle_transform()` behaviour for

why we would need inverted values here.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2459>
- Drop bogus `meta_monitor_transform_invert()`. It papered over
wrong `meta_rectangle_transform()` behaviour for non-flipped
output transforms.
- Update `scale_and_transform_cursor_sprite_cpu` to match the GL
pipeline matrix in `MetaShapedTexture`, fixing several of the
flipped cases. Note: the rotation applied is the one a client would
need to apply to the buffer for a given monitor transform.
- While on it, drop a redundant `return`.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2459>
With `META_MONITOR_TRANSFORM` values matching their `WL_OUTPUT_TRANSFORM`
counterparts, the definition from the Wayland spec applies: the
`META_MONITOR_TRANSFORM` value tells us how the output was rotated
and that the buffer was drawn by the client to compensate for that.
The matrix describes the transformation from surface- to buffer-
coordinates, so the operation we need here is the same one that
the client applied (not from buffer- to surface-coordinates, i.e.
the inverse).
While on it fix `FLIPPED_90` and `FLIPPED_270` to use the correct
axes: flip on the x-axis, rotation on the z-axis.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2459>
`meta_rectangle_transform()` is used in the stack to *compensate* for a
`MetaMonitorTransform` applied to a output, not to apply it again.
Change the function accordingly.
Context:
Experimenting with direct scanout on offscreen-rotated outputs revealed
that the 90/270 degree cases were actually interchanged.
Further digging revealed that we use `meta_rectangle_transform()` with
those values swapped in every single case, papering over the issue.
Either a unintuitive and unexplained `meta_monitor_transform_invert()`
was added, in which case "flipped" values would be wrong, or, in case
of Wayland buffer transforms, the values were swapped by interpreting
the Wayland enums accordingly, see commit 8d9bbe10.
Swapping the 90/270 degree values in `meta_rectangle_transform()`:
1. fixes hardware cursor positioning with flipped output transforms
2. fixes rendering issues with offscreen-rotated flipped output transforms
3. allows us to drop unexplained `meta_monitor_transform_invert()`s in
follow-up commits
4. allows us to make `META_MONITOR_TRANSFORM` and `WL_OUTPUT_TRANSFORM`
enums match again (reverting 8d9bbe10, as already done)
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2459>
The following implicit definition for `transform()` did not
correctly apply:
```
a * b = c
c * invert(b) = a
```
Crucially the following did not apply for `FLIPPED-90`
and `FLIPPED-270`:
```
a * invert(a) = identity
```
Fix this by applying the operations, first the flip, then the
rotation, in this order and add tests to ensure correct results
for the requirement above.
Also drop `relative_transform()` as it only had a single user and
can be replaced by `transform()`:
```
invert(a) * b = c
a * c = b
```
As this is not very intuitive, ensure in tests as well.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2459>
Checking for both bits at once means only one matching bit is
sufficient - very likely in case of `rotate-0'.
This fixes crashes on hardware that does not support 'reflect-'
bits when setting a flipped output transform.
While on it, also update the check for `reflect-y` instead of
`reflect-x` + `rotate-180`. They are logically equivalent,
however some hardware may support `reflect-y` but not both
other bits.
Fixes commit 4e3f3842a1
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2459>
As testing of direct scanout revealed, `META_MONITOR_TRANSFORM`
does actually match `WL_OUTPUT_TRANSFORM` enums. The fact that
things rendered correctly with 90/270 degree values swapped
was because other parts of the stack got the interpretation
wrong, most notably `meta_rectangle_transform()`.
Thus lets revert this change and fix the stack accordingly.
This reverts commit 8d9bbe109b.

We started to report resource changes using prediction when an update
had been successfully committed. While at it, gamma changes were
reported too, but this was problematic, as gsd-color will listen for the
MonitorsChanged D-Bus signal and naively set the gamma again, even if it
didn't change. There aren't currently any actual use cases for being
told when gamma changes from a prediction, so just ignore it and just
report privacy screen changes.
This avoids a feedback loop between mutter and gsd-color.

Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2527>
When we change the privacy screen, we added a result listener to the KMS
update object to notify the upper layer about the privacy screen state
change. This was slightly awkward as one might have changed the state
multiple times for a single update, thus it was necessary to remove any
old result listeners to an update before adding a new one.
Doing this will not be possible when updates are fully async and managed
by the KMS impl device.
To handle this, instead make the post-commit prediction notify about
changes that happens in response to a successfully committed update. We
already predicted the new privacy screen state, so the necessary change
was to plumb the actual change into a callback which emits the signal if
there actually was a privacy screen change.
This will then be communicated via the same signal listener that already
listens to the 'resources-changed' signal.

The name had a bit conceptual conflicts with MetaKmsUpdate, as it shared
its namespace but had no relation to it. Fix this by renaming it
MetaKmsResourceChanges (and the corresponding META_KMS_UPDATE_CHANGE_*
to META_KMS_RESOURCE_CHANGE_*). The term "resource" is used since that's
already used in the signal, and the fact that the changes partly comes
from changes in the DRM resource as retrieved by drmModeGetResources.

With this header we can set a flag to signal that the whole buffer is
corrupt and should be ignored. With this we can cater to all cases:
* Window buffer fine, but cursor broken:
Use the spa_meta_cursor properties like id or offset accordingly
* Window buffer broken, but cursor fine:
Use the chunk flags
* Both are broken / the dequeued buffer is not usable
Use the spa_meta_header flag
Additionally clients can now check if a buffer contains spa_meta_header
data and can thus only check for the new or the old behaviour.

PipeWire supports flags to signal a corrupted buffer. We should use the
flag SPA_CHUNK_FLAG_CORRUPTED for `chunk->flags` instead of setting
`chunk->size = 0` since the size isn't well defined for arbitrary dmabufs
and should be set to 0.
Sadly clients like obs are using a chunk size of 0 to decide if a buffer
should be imported. Thus we should offer both until clients are using
the flag.

When building the list of formats to be sent as part of the scanout
tranche, avoid requiring modifier support by the DRM driver for
formats relying on implicit modifiers (DRM_FORMAT_MOD_INVALID).
Specifically, the previous check required the DRM driver to have
advertised some modifier support for the given format in its
IN_FORMATS KMS plane property, regardless of modifier it was. If it
hadn't, the format was left out of the list of formats to be sent
in the scanout tranche.
When no formats remained to be sent in the scanout tranche, the
tranche simply wasn't sent.
This resulted in the scanout tranche never being sent for GPUs where
modifiers aren't supported. In those cases, no formats are advertised
using the IN_FORMATS property, and thus the list of formats to be sent
in the scanout tranche remained empty.
Since Mesa doesn't use scanout-compatible buffers for native Wayland
clients unless specifically requested to do so using the "scanout"
tranche flag, it effectively means that direct scanout of native
Wayland clients wasn't supported for GPUs without modifiers support.
Sending a tranche with formats paired with the implicit modifier
(DRM_FORMAT_MOD_INVALID) is both allowed by the protocol and is
already done by default for GPUs with modifiers support, unless the
experimental support for explicit modifiers is enabled in Mutter.
So instead of requiring modifiers to be supported for each format
being evaluated for the scanout tranche, when processing formats
which rely on implicit modifiers, only check if the format in
question is supported by the DRM driver for scanout on the primary
plane.

While the check for `clutter_actor_has_mapped_clones` clearly indicates
an intention to take clones into account, the following code
does not do so, likely because it predates the introduction of
`clutter_actor_is_effectively_on_stage_view()`.
Switch to that newer API in order to take clones into account. This
avoids unnecessary `wl_surface_send_enter()` and `wl_surface_send_leave()`
events when entering the overview, reducing client work.
This also avoids unnecessarily allocating a `cairo_region_t`.

`clutter_actor_set_child_at_index()` is far from a no-op, even if

Unparenting the surface actor when the subsurface object is destroyed
has several issues:
- subsurface actors can be unparented while a close animation is
still ongoing, breaking the animation for e.g. Firefox.
- adding and removing the actor to/from the parent is not handled in
one place, making the code harder to follow.
- if the destroyed subsurface had children of its own, they potentially
stick around until a surface-tree rebuild. This makes the Firefox
hamburger menu not close with the "compositor" backend.
Move the unparenting back to
`meta_window_actor_wayland_rebuild_surface_tree()` and instead just
notify the parent of a state change, if it still exist. This will ensure
a correct mapping between the subsurface node tree and the flat surface
actor list. In case of the closing animation the parent will already be
removed and the call is skipped.

Since b443bd42ac, we unmanage a wayland window when clearing its
transient parent. That's to make sure that xdg-foreign doesn't
leave the dialog around after the imported surface was destroyed.
While that behavior is sound, it is problematic to implement it
by unmanaging the window, as that happens entirely behind the
client's back.
Instead, send a close event for the window. Unless the client has
good reasons, it should honor the request. (And if it has good
reasons - like unsaved work - then effectively hiding the window
from both the user and client is probably not the best idea anyway).

Not all windows can be minimized: X11 clients can disable the
functionality, and so do we for windows that aren't shown in
the alt-tab popup or the shell overview, so there would be no
way of getting them back.
While we make sure that we respect that ourselves (keybinding,
window menu, etc.), we don't guard meta_window_minimize(), so
clients or extensions can still minimize a window that isn't
supposed to be minimized.
That can lead to all kinds of issues, from the hidden window
being lost (as far as users are concerned) to a crash when
the minimzed window has a transient parent.
Just add an explicit check to make sure the unexpected doesn't
happen after all, and print a warning if it does.

The cursor rendering code path used by the screen cast code relies on
the cursor tracker machinery to determine where to blit the cursor
texture, but at the moment the cursor position invalidation is behind
a check for whether the shell is using a Wayland backend. (This code
path used to be Wayland-specific before 00cbcb7ba1 but has been
backend-agnostic since).
This commit removes the check for a Wayland compositor, allowing
cursor drawing to function correctly on X11 when screen casting in

The test case checks that the stage views of hidden actors are
not updated when the views of the visible outer parent change.
The check for the outer parent's updated stage views currently
relies on ClutterFixedLayout not excluding hidden children in
its size request: As the container doesn't contain any visible
children at that point, its size would change to 0x0 and end
up on no stage view (rather than the assumed two).
Avoid that oddity by giving the outer container a fixed size,
so that the visibility of its child doesn't affect the test
when we fix ClutterFixedLayout.

The test aims to test that trying to fetch X11 clipboard content after
Xwayland went away doesn't cause issues. What happens though is that
sometimes the clipboard content doesn't have time to settle (i.e. fetch
mime types etc) before Xwayland gets terminated, which causes flakyness.
Fix this by waiting for the compositor side clipboard owners to finish
setting up before continuing.

The pixel clock determines how fast pixels can be processed. When adding
non-native common modes, avoid adding modes that exceed the max pixel
clock frequency of the native modes. Avoiding these avoids potential
mode setting failures where the GPU can't handle the modeline since the
configured pixel clock is too fast. This replaces the "bandwidth" check
which used the number of pixels and refresh rate, which wasn't enough to
avoid incompatible modes.

'screen-cast/monitor-src: Use clutter_stage_paint_to_buffer'
(6c818cd8d5) made the non-dma-buf path use
clutter_stage_paint_to_buffer() to avoid running into direct scanout
issues. At a glance, the dma-buf paths didn't have the same issue since
it explicitly handled dma-bufs by blitting them.
What it also did was move the recording to an idle callback, to avoid
paint reentry issues. A side effect of this, however, is that it also
broke the dma-buf paths, as they rely on the back buffer existing, and
the stage view direct scanout already being setup, which it isn't in an
idle callback.
Fix this by using the dma-buf variant of
clutter_stage_paint_to_buffer(): clutter_stage_paint_to_framebuffer().
This has some negative performance impact, but we can't use
cogl_blit_framebuffer() when using an idle callback for recording.
Potential performance improvements to make things work more as they did
before is to enhance 'cogl_blit_framebuffer()' a bit, making it a vfunc
that could be implemented by MetaOnscreenNative. A flag to say whether
to look at the back or front buffer would let MetaOnscreenNative know
whether to use the already committed-to-KMS buffer, or the current back
buffer.

Add `sync_effects_completed()` and `verify_view()` in
order to allow Wayland test clients to trigger verifications
and add convenience functions to use them to client-utils.
Notes:
- `sync_effects_completed()` works in two stages in order
to ensure it doesn't race with window effects. By the time
`sync_effects_completed()` is processed, an effect could
already have ended or not yet been scheduled. Thus we
defer a check for pending effects to the next paint cycle,
assuming that by then they should have been scheduled.
- `meta_ref_test_verify_view()` internally triggers the
`paint` signal for the stage which is why it can not be run
in the after-paint signal handler.

Our internal interpretation of output transforms is not in line with
the Wayland spec. Wayland describes them as the transform that a
compositor will apply to a surface to compensate for the rotation
or mirroring of an output device - counter-clockwise.
Mutter in turn interprets it the other way around. One could
argue it does the same but clock-wise - or it interprets the transform
from the viewpoint of the content, not the device.
In either way, the difference is that 90 and 270 degree values are
switched. Thus swap these accordingly when we translate from
`WL_OUTPUT_TRANSFORM` to `META_MONITOR_TRANSFORM`.

in this case we just ended up with warnings since the refresh rate was
NaN. Fix this by making it 0.0 to mean "no refresh rate". This also is
what 'xrandr' itself reports.
Fixes warnings when launching 'mutter --x11' in Xvfb.

This adds a minimalistic fullscreen direct scanout test case, that runs
on vkms. It doesn't use EGL, and it uses uninitialized memory, thus it
lacks any kind of implicit synchronization, but it does test that the
scanout selection paths are working.
What is tested is:
* DMA buffer allocated using gbm on top of VKMS
* Buffer passes a mode setting TEST_ONLY check
* Paint is omitted
* Correct buffer active in KMS after presentation
What isn't yet tested:
* Implicit synchronization related behavior
* Presented pixel content

We passed the pointer to a GError * as user data on an async I/O call.
The callback function didn't make use of it, so it was never written to,
thus remained NULL, thus was dead code. Remove it.

It works by using an X11 client to set the clipboard content, using a
mimetype that on purpose is not handled by the clipboard manager. The
test then makes sure we don't crash when trying to transfer data from
the old X11 selection source.

The Xwayland server can go away at any time; when this happen we might
have a test client running, and for it to tear down more nicely, make
sure to avoid trying to clean up X11 resources on the old X11 display.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2364>
Xwayland can disappear at any time, for example during a new_async() or
read_async() call. When we eventually finalize the stream, the X11
display it was created for is gone, thus can't clean up the X11
resources. Handle this by making the MetaX11Display pointer a weak
pointer, and ignore cleaning up if it disappeared. This is fine since
the X11 server it created those resources one is gone already.

The property doesn't necessarily exist when using drivers that doesn't
support atomic mode setting, and the way it worked will break night
light and other gamma related features. This makes things use the gamma
length; if it is higher than 0, it definitely supports it one way or the
other, i.e. GAMMA_LUT with the atomic backend, and drmModeCrtcSetGamma()
with the legacy/simple backend.

It doesn't depend on whether the CRTC is active or not, so always read
it. This is also useful to know whether a CRTC supports gamma, before it
is being turned on, without relying on the existance of properties.

The COMPOSITOR_GRAB event route has effectively been replaced by
ClutterGrabs, which are no longer covered by the existing check.
So check for grabs as well to restore the old behavior.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2436>
The event-route is never set to COMPOSITOR_GRAB nowadays, so the
condition will never be met.
Furthermore, it is expected that ClutterGrabs only happen when
events are routed normally, so the remaining NORMAL check should
already fully cover the old COMPOSITOR_GRAB case.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2436>
We already bypass wayland if there is a ClutterGrab, so the case
that used to be covered by the event-route check is already handled,
and we can just remove the obsolete check.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2436>
Since the new ClutterGrab API replaced the old plugin-modal hook,
the event-route is never set to COMPOSITOR_GRAB.
The code in question already checks whether the stage has a grab,
so we can just remove old checks.

Initializing the event mask, SubstructureRedirectMask in particular,
before taking the manager selection fails with BadAccess. Fix this by
initializing said mask after taking the manager selection.
This fixes `--replace`.

The code is already trying to avoid creating new laters when there
already is one for the queue type, but this wasn't working because the
ID of the later was never stored after creating a new one. This would
then result in as many laters as meta_display_queue_window() was called
and all of them would run the handler function, even if only the first
one had a non-empty window queue.
Similarly this was causing the later to not be removed if the window
queue got empty after meta_display_unqueue_window().
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2414>
Currently the signal is getting emitted accidentally, because even when
removing a window from the queue, the later handler of that queue will
still get run due to a bug. This bug is going to get fixed in the next
commit, but some things might depend on the signal getting emitted when
the visibility of a window has changed.
This change affects the behavior in two ways. First the signal is now
emitted immediately rather than from an idle. And second it now
correctly includes the window in the should_show or should_hide list.
