While multiple built-in panels isn't actually supported in any
meaningful manner, if we would ever end up with such a situation, e.g.
due to kernel bugs[0], we shouldn't crash when trying to set an
'external only' without any external monitors.
While we could handle this with more degraded functionality (e.g. don't
support the 'switch' method of monitor configuration at all), handle it
by simply not trying to switch to external-only when there are no,
according to the kernel, external monitors available. This would e.g.
still allow betwene 'mirror-all', and 'linear' switches.
The crash itself was disguised as an arbitrary X11 BadValue error, due
to mutter trying to resize the root window to 0x0, as the monitor
configuration that was applied consisted of zero logical monitors, thus
was effectively empty.

xkb recently gained support for user-specified keymaps, which means we
can no longer assume that the configuration data is necessarily fully
complete or correct; and the configuration language is quite a labyrinth,
so it's easy to get wrong. If setting the keymap fails, leave it in
whatever state it previously had, since that seems preferable to crashing
with a NULL pointer dereference.

Sometimes the automatically selected primary GPU isn't suitable with no
way to make an well educated guess to do it better. To make it possible
for the user to override the automatically calculated default, make it
possible to override it using a udev rule.
E.g. to select /dev/dri/card1 as the primary GPU, add a file e.g.
/usr/lib/udev/rules.d/61-mutter-primary-gpu.rules (path my vary
depending on distribution) containing the fellowing line:
ENV{DEVNAME}=="/dev/dri/card1", TAG+="mutter-device-preferred-primary"
Reboot or manual triggering of udev rules to make it take effect may be
required.

Instead of aborting with an error, display a half transparent gray
square instead of cursors and log a warning in the journal, allowing the
user to fix their system withotu having to rely on switching to a TTY.
It will be immediately obvious the cursor is silly looking, which will
be a better hint than just aborting.

Monitor tile info is possible to fetch when RANDR version 15 is exposed
by the X11 server. We had inverted the check meaning that only if older
versions were advertised would we attempt to init the tile information.
Fix this guard, thus fix monitor tiling on X11.

Not calling libinput dispatch in the backend constructor defeats the
logic in post init as the device added events have not been processed
yet.
So instead of trying to guess the cursor initial visibility, simply
update it along when devices get added.
Additional benefit, we do not need to walk the all device list looking
for touchscreens anymore, we just need to check the device being added
since the current logic is to hide the cursor as soon as a touchscreen
is found.

At startup, libinput dispatch is called from the MetaSeatNative
constructed callback.
That means that we may get libinput events even before the default seat
is set.
In turn, processing those events may trigger the use the default seat
while it's still not set yet, and cause a crash of gnome-shell/mutter
at startup.
A simple reproducer for this is to start gnome-shell/mutter with a
tablet connected and the stylus in proximity, the proximity event will
cause gnome-shell/mutter to crash at startup.
To avoid that issue, avoid dispatching libinput events early from the
MetaSeatNative constructed callback, those events will eventually get
processed when the seat and the backend are all setup.

Rely on the seat stage, or other ways to fetch it. Also rely that
there is actually a single stage, so that we assign the right stage
to all events going out of the seat, in a single place.

This is a bit scattered around, with the setter/getter in Clutter, and
it only being only directly honored in Wayland (it goes straight through
device properties in X11).
Make this private native API, and out of public ClutterInputDevice API.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1486
Make the upper part agnostic about the device being relative in order
to avoid applying keep-aspect. The X11 bits already are, so make it
sure it's also the case for the native backend.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1486
As it does seem from a read to libinput code, TOUCH_CANCEL events
actually do contain slot information, and are emitted per-slot.
This means we can avoid iterating over the slots ourselves, they
are still expected to be sent altogether.

When malformed modes are provided and no valid mode spec is found, mutter
will eventually try to access the last element of an empty list. Warn about
this and exit properly.

Many tablets have a native portrait mode panel, yet come with a keyboard dock,
where the device gets docked in landscape mode. To avoid the display being
on its side when mutter starts while the tablet is docked, we need to take
the accelerometer reported orientation into account even if there is a
tablet-mode-switch which indicates that the device is NOT in tablet-mode
(because it is docked).
Add special handling for the first time the "orientation-changed"
signal gets signalled by the orientation-manager, which happens after it
has successfully claimed the accelerometer with iio-sensor-proxy.
The added special handling of the initial "orientation-changed" signal
does a number of checks:
1. panel_orientation_managed is false because of the tablet-mode-switch and not
because of other reasons.
2. The device has a native portrait mode panel (and thus likely needs rotation
to display the image the right way up when docked).
If all these checks succeed then it continues with creating a new
monitors-config based on the orientation ignoring the panel_orientation_managed
value (for the initial/first "orientation-changed" signal only).
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1506
The orientation reported by the orientation_manager may have changed while
panel_orientation_managed was false. So when panel_orientation_managed
changes to true we should re-check the orientation.
This fixes the orientation not being correct when e.g. taking a 360 degree
hinges 2-in-1 in clamshell mode (so landscape orientation) and then folding
it into tablet mode while holding it in portrait orientation.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1506
Add support for the (mostly theoretical) case of an input-device
offering tablet-mode-switch functionality being unplugged.
This makes the has_tablet_switch handling identical to the has_touchscreen
handling, leading to more consistent code.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1506
Detect if a tablet-mode-switch device is already present when mutter
starts by checking for this from meta_seat_native_constructed. This
mirrors how we also set has_touchscreen from meta_seat_native_constructed.
This fixes tablet-mode-switches only being recognized when they are added
at runtime.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1506
Unconditionally setting has_touchscreen to check_touch_mode
when a new device gets added leads to has_touchscreen becoming
false when during runtime e.g. an USB keyboard gets plugged in.
Fix this by setting has_touchscreen to TRUE when check_touch_mode
is TRUE and leaving it alone otherwise.

A first step towards abandoning the CoglObject type system: convert
CoglFramebuffer, CoglOffscreen and CoglOnscreen into GObjects.
CoglFramebuffer is turned into an abstract GObject, while the two others
are currently final. The "winsys" and "platform" are still sprinkled
'void *' in the the non-abstract type instances however.
