So far, the tests relied on the host system to provide pipewire and
wireplumber. This seperates the tests from the host system which is
especially useful if the tests are run in a toolbox which has a
different pipewire installed than the host. It also should make it
harder to have a mismatch between the pipewire library and the pipewire
daemon.

We're already inhibiting real time scheduling when reading new KMS state
after hot plugs, as well as when during mode sets, due to the kernel not
being able to reliably handle these within the 250 ms limit. However, we
didn't do this during initial probing, which meant that occasionally
we'd run into these kind of issues during startup.
Handle this by always inhibiting real time scheduling up front, and
don't uninhibit until all initially discovered device have finished
processing their initial mode set.

If an application is maximised, clutter_stage_pick_and_update_device()
goes into the
if ((flags & CLUTTER_DEVICE_UPDATE_IGNORE_CACHE) == 0)
condition and returns the current actor for the device. This means no
CLUTTER_LEAVE/ENTER events are generated and in turn means the focus is
never invalidated and updated.
This leads to tool->focus_surface always being NULL and all events are
discarded.
Notably, tool->current is set to the right surface but
that one never changes either so meta_wayland_tablet_tool_set_current_surface()
exits early too because surface == tool->current and we thus never call
meta_wayland_input_invalidate_focus().

that signal to then notify wayland clients of removed tablet devices.

we never get to the point where we send out the signals and thus never
remove the tablets.

Using GL_BGRA8_EXT as internalformat for TexSubImage2D was not allowed
in the EXT_texture_format_BGRA8888 extension. This changed recently:

1.4, 23/06/2024 Erik Faye-Lund: Add GL_BGRA8_EXT for ES 2.0 and later.
Mesa already supports this which is why 7f943613a8 ("cogl: Use sized
internal renderable formats") worked as intended. Technically spec
compliant and our CI had an up-to-date driver.
So while this is no bug, it's still not great because older drivers will
generate GL errors. This commit changes this specific format back to an
unsized internal format which means we could, in theory, get less than
8bpc framebuffers.
We can try to revert this commit when newer driver versions have
propagated far enough.

Let's add a bunch of tests for the newly introduced monitor config
migration code. We're verifying that:
- monitor configs get migrated and monitors.xml is updated on startup
- existing monitor configs in LOGICAL layout mode (ie.
"scale-monitor-framebuffers" was enabled before updating mutter) get
migrated
- the migration of various more complex monitor layouts from PHYSICAL
to LOGICAL layout mode works
- for monitor layouts where conversion to LOGICAL fails, the PHYSICAL
layout mode still is migrated, while for LOGICAL at least primary
monitor and disabled monitors are preserved
- simple monitor configurations (with no scaled monitors, or with only
"irrelevant" scaled monitors at the end of the layout) do not go through
the conversion code paths
- monitor configs in PHYSICAL layout mode with integer scale factors
which will result in non-integer logical monitor sizes get converted
to the closest fractional scale factor
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3596>
We don't want to do the work of the layout mode detection and conversion
every time we read the monitors.xml file.
Instead, when the detection logic is used, set a flag to automatically
update the config files after the parsing is finished.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3596>
Introduce some "best effort" conversion code to migrate monitor configurations
from PHYSICAL (the old default) to LOGICAL (the new default on wayland)
layout mode.
This conversion will only be used when the old PHYSICAL layout-mode
configuration is not compatible with the new LOGICAL layout-mode one.
This only applies if 1) there's a monitor that needs scaling in the
layout, and 2) the scaled monitor comes before other monitors in the
coordinate system (ie. it's not the rightmost or bottommost monitor).
There are two algorithms added here to convert monitor layouts:
- One for "simple" 1-dimensional monitor layouts, where all monitors are
aligned on a vertical or horizontal strip.
Here's a few (inaccurate) examples of how this would look with different
layouts (left side is PHYSICAL, right side is LOGICAL, x is the origin of
the coordinate system, the numbers are scales of the monitors):
```
x──────┬──────┬──────┐ x ┌──────┐
│ 2 │ 1 │ 2 │ 2┌──┤ 1 ├──┐2
│ │ │ │ ──► └──┤ ├──┘
└──────┴──────┴──────┘ └──────┘

└──────┤ │ └──────┘
│ ├────┐
│ │ 1 │
└────┴────┘
```
- A second more complex algorithm for 2-dimensional monitor layouts with
a common baseline that all monitors are aligned to.
And examples for this one:
```
x ┌──────┐
┌──────┤ │
│ 1 │ 2 │ x──────┐
│ │ │ │ 1 ├────┐
└──┬───┴───┬──┘ ──► │ │ 2 │

│ 2 │ │ 2 │

```
These algorithms will fail for any more complex 2d monitor layout, eg.
```
x ┌───┬────┐
│ 2 │ 1 │
│ ├────┘
┌───┴┬──┘
│ 1 │
└────┘

└───┴───┴───┘
```
In those cases where the conversion failed, we fall back to aligning
the monitors on a horizontal line, preserving the scale, the primary
monitor and the disabled monitors.
Note that we also need to convert the scale factor in some cases,
because LOGICAL layout mode also behaves different here:
When the scale results in a fractional logical monitor size (eg.
the native monitor width is 2560px, and a scale of 3 is set =>
2560px / 3 = 853.333px), in LOGICAL mode we won't use that scale.
Instead we have an algorithm (see
meta_monitor_get_closest_scale_factor_for_resolution()) to find
the nearest fractional scale factor which doesn't result in
fractional logical monitor size. We reuse this algorithm here for
the conversion.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3596>
We'll reuse meta_monitor_get_closest_scale_factor_for_resolution() for the
conversion of monitor configs, and during those conversions, we probably don't
want to impose the same limits to fractional scales that we usually impose.
This means that we can even convert physical layout configs where the user
manually changed to a value higher than what our fractional scale calculations
would allow.
Move this check into the calling function so that it's not imposed by
meta_monitor_get_closest_scale_factor_for_resolution() directly.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3596>
When there is no layout mode set in a logical monitor config, we currently just
assume the configuration matches the mode that the system expects. This blows
up when the layout mode expected by the system changes (eg. by turning on
"scale-monitor-framebuffers" in mutter): Suddenly configs fail the validation
check and get thrown away.
Since we now can add one configuration for each layout mode to the config store,
we can do better here: Let's only add configurations to the store where we
verified beforehand that the monitor layout is compatible with that mode, either
because we set it ourselves using the <layout_mode> key, or by detecting which
modes the layout is compatible with.
Also update monitor config ifiles to adjust for the new layout_mode, as
they all are assumed to be "logical".
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3596>
Verify even more assumptions we make about logical monitor configs:
- Have a more explicit check that the monitor modes in the logical monitor are
all equal
- Complain if scale factor with physical layout mode is fractional
- Make sure that scale factor with logical layout mode actually scales to a
non-fractional width and height
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3596>
We'll need a few of those things from the monitor config store soon, also it's
generally useful to have a prefix which makes it clear where functions are
defined.
So factor some things out into a new monitor-config-utils.c file.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3596>
Store and load the layout mode for each logical monitor configuration in
monitors.xml by introducing a new <layoutmode> element. The value of the
element can be either "logical" or "physical". The layout mode is also
made part of the monitor configuration key.
Right now this isn't doing a lot:
When no <layoutmode> is found on the config (this is the case with all
existing configs), we'll keep using the layout mode expected by the system,
without updating the config file.
When changing an existing, or introducing a new configuration, we'll now
store the current layout mode with the config though, and load it again
on the next start of mutter. This is still not problematic as long as
mutters expected layout mode doesn't change (eg. by turning on/off
"scale-monitor-framebuffers").
When the expected layout mode of mutter switches between
restarts, the monitor config is now still loaded but remains unused,
and mutter will create (and store) a new one with the other layout mode.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3596>
We'll introduce some new migration code with the next few commits to introduce
a layout_mode property in monitors.xml. This will be significantly easier
without keeping around the old monitor migration code, so drop it.

We have meta_verify_logical_monitor_config() already, and it does a few checks that
meta_verify_monitors_config() doesn't do yet, so let's also call
meta_verify_logical_monitor_config() when verifying the whole config.
We'll rely on this being part of meta_verify_monitors_config() soon, because we'll
stop calling meta_verify_logical_monitor_config() from the config parser.

The first event happening for a new touch will be the CLUTTER_ENTER

And notably, don't cancel touch when an event handler is being
removed. Touch events are largely unaffected by most Wayland
grabs (pointer constraints, popups), so we might be cancelling
input too early if one of these wayland grabs was effective when
touch interaction began, but stopped sometime between touch updates.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3889>
Touch events are implicitly grabbed to the surface they began in,
and are not affected by the focus handler. However these events
will appear to come from the core pointer device, which might lead
to the wrong device being updated.
Ignore events with a sequence, since the default focus handler
does not intend to do anything with them.

On a hybrid machine with i915 primary and nvidia-drm (470) secondary,
`meta_render_device_egl_stream_initable_init` calls
`meta_kms_inhibit_kernel_thread` to change from the default 'kernel'
thread type to 'user'. And soon after that it would
`meta_render_device_egl_stream_finalize` because I'm not actually
using that GPU, and calls `meta_kms_uninhibit_kernel_thread`.
So during startup Mutter would default to a realtime kernel thread,
switch to a user thread (which doesn't support realtime), and then
switch back to a realtime kernel thread.
In the middle of all that, while the thread type was 'user' and
realtime disabled, something was invoking `ensure_crtc_frame` which
created a `CrtcFrame` without a deadline timer. Soon after that the
thread type changed back to 'kernel' with deadline timers expected, but
our existing `CrtcFrame` has no deadline timer associated with it. And
so it would never fire, causing the cursor to freeze whenever the primary
plane isn't changing. And the problem was permanent, not just the first
frame because each `CrtcFrame` gets repeatedly reused (maybe shouldn't
be called a "Frame"?).
Now we adapt to switching between kernel and user thread types by adding
and removing the deadline timer as required.

If we finish compositing in time, the composited result will be
submitted prior to the deadline timer is triggered, and we'll be fine,
and if not, at least the cursor updates will be smooth, which makes it
appear smoother than not.
There is a risk that this can negatively impact composited updates when
moving the cursor, so make it possible to toggle a paint-debug flag for
now until this has been more tested.
This also mean we need to disarm the deadline timer after handling
update, as there might be a scheduled cursor update pending, but we
already handled it, so disarm the timer.
Here is an illustration of the difference.
In the following scenario, with disarming, the composited frame E, and
the cursor movement C gets presented. With this branch, only the cursor
movement C gets presented.
```
* A: beginning of composited frame
* B: begin notification reaches KMS thread
* C: cursor moved
* D: calculated deadline dispatch time (disabled with the branch)
* E: KMS update posted
* F: KMS update reaches KMS thread
* G: actual deadline (and with branch and gets committed)
Compositor thread: --------A---------------E---------
\ \
\ \
KMS thread: -----------B------C----D---F-G----
```
In the following scenario, by not disarming, the cursor update C will be
presented, and the would-be-delayed composited frame E would be delayed
anyway, i.e. fixing cursor stutter.
```
* A: beginning of composited frame
* B: begin notification reaches KMS thread
* C: cursor moved
* D: calculated deadline dispatch time (and with branch will be dispatched)
* E: KMS update posted
* F: actual deadline
* G: KMS update reaches KMS thread (and with branch gets postponed)
