A client may provide a positioner that places the window outside of its
parent. This isn't allowed, according to spec, so we hide the window and
log a warning. This, however, leads these affected clients with an
incorrect view of what is mapped or not, meaning it becomes harder to
recover.
Fix this by sending xdg_popup.done when we hide the popup due to an
invalid position. Don't error out the client, let the bug slide, as
that's a less jarring experience for existing applications that
reproduce this than being disconnected, which practically feels like a
crash.

In constrast to x11, Wayland has sane handling for touch events and
allows the compositor to handle a touch event while the clients are
already seeing it. This means we don't need the REJECTED state on
Wayland, since we can also grab sequences after the client has seen
them.
So disallow moving sequences to the REJECTED state on Wayland.

Updating of the paint volume used for culling these days happens
during the finish-layout stage, not while painting. Also we have
geometry-based, not paint-based picking anymore.

Rename the `last_paint_volume` to `visible_paint_volume`: That avoids
confusion with the `had_effects_on_last_paint_volume_update` flag and
also makes it clear that this paint volume is the currently visible one.

Rename the paint_volume_valid flag to has_paint_volume in order to
better reflect what it's for.
The name "paint_volume_valid" implies that the paint volume can be
invalidated and thus sounds like it's involved with some kind of
caching. The flag that's actually involved with caching is
"needs_paint_volume_update", while "paint_volume_valid" is only meant to
store whether the actor has a paint volume to work with.
So rename paint_volume_valid to has_paint_volume to avoid confusion
about which flag is used for caching.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1492>
For clarity and for further improvements, introduce a separate function
to update the paint volume instead of doing that inside
_clutter_actor_get_paint_volume_mutable().
Also add a FIXME comment for a possible bug I noticed while working on
it.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1492>
Since ClutterActor now properly caches its paint volume and ClutterText
tries hard to invalidate its own cached paint volume on every redraw
anyway (that's more often than ClutterActor invalidates its own paint
volume), we can simply rely on the caching of the paint volume done by
ClutterActor and invalidate that on every redraw.
So remove the private cached paint volume from ClutterText and all its
invalidation machinery.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1492>
The function _clutter_paint_volume_get_stage_paint_box() actually
doesn't modify the paint volume that's passed to it, so make that a bit
more clear by passing a const paint volume as the argument.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1492>
These days it's possible to chain up into the default get_paint_volume()
implementation again, which renders
clutter_actor_get_default_paint_volume() unnecessary. So remove that
function and move clutter_actor_update_default_paint_volume() back into
real_get_paint_volume() where it belongs.

When modifiers are enabled on mutter on some of the older i915 systems observed
Black-screen on 2nd monitor during multi-head use cases, upon debugging observed
that disabling modifiers on these systems resolved the Black-screen issue:!1618.
This issue depends whether we have enough DBuf space to provide required bandwidth
for the userspace demands. Those platforms which have less Display Buffer, will
just have more chance to face lack of it. However it still depends on various
factors like amount of planes(i.e the more planes we have, the more we divide the buffer),
refresh rate, bpp and so on.
This affects watermark calculations and the minimum blocks required for at least
wm level 0. If we don't have sufficient ddb at least for wm0 for all planes in
the configuration then it is rejected.
Until we have TEST_ONLY commit solution is built we could make sure to disable
modifiers support on these older i915 systems based on udev rules defined in this commit.
This commit makes sure that modifiers are still usable on latest i915 systems.

It's not really a backend thing, and we'll want to profile e.g. loading
the backend too, so create it very early and destroy it very late and
let MetaContextMain own it.

This reverts commit eac227a203.
Currently, Flatpak applications can bypass the X11 permission setting
and access the X server through abstract sockets because X11 authentication
is not enforced for the current user ID.
Fix this by always requiring X11 authentication for Xwayland. This also
means applications without XAUTHORITY set to the file with Mutter's
Xwayland credentials cannot connect to X, including apps launched from
VT or SSH.

When deciding if a window should be unredirected because it was causing
fullscreen damage in the past, it was not considered whether the window
is still fullscreen. This could result in a floating window being
unredirected if it was chosen for unredirection because of
_NET_WM_BYPASS_COMPOSITOR = 1 and was previously fullscreened for >= 100
frames, long enough to change does_full_damage, before getting
unfullscreened.

Back in 2014 sending pressed keys to Wayland clients caused issues,
because at least Xwayland didn't handle that gracefully, causing issues
like ghost-pressed keys. A way it was reproduced was quickly alt-tab:ing
to and from a Firefox window, which would cause the File menu bar
incorrectly appearing.
While this was reported to the Xwayland component back then, it was,
probably by mistake, assumed to be an issue in mutter, and mutter
stopped sending pressed key events on enter.
The following year, Xwayland was eventually fixed, but the work around
in mutter has been kept around until it was again noticed as an
inconsistency between compositor implementations.
Lets remove the work around, and follow the spec, again.
This reverts commit c39f18c2d4.

We'd set the capabilities to 'none', meaning all previously enabled
device classes would be disabled. That means we shouldn't re-disable
them directly after.
This ensures '..disable()' is only called once for every '..enable()'.

We traverse the whole screnegraph anyway these days in finish_layout(),
so no need for the whole "set the flag on parents even though we don't
need it" dance anymore.

With high frequency mouse devices, we would send very many configure
events per each update cycle, which had the end result that some clients
constantly re-allocating and redrawing their buffers far too often, if
they did this in direct response to xdg_toplevel configure events.
Lets throttle the interactive resize updates to stage updates, to avoid
having these clients doing the excessive buffer reallocation.
This also removes some old legacy X11 client resize throttling, that
throttled a bit arbitrarily on 25 resizes a second; it is probably
enough to throttle on stage updates for these clients.

Some mice send a value slightly lower than 120 for some detents. The
current approach waits until a value of 120 is reached before sending a
low-resolution scroll event.
For example, the MX Master 3 sends a value of 112 in some detents:
detent detent
| | |
^ ^ ^
112 REL_WHEEL 224
As illustrated, only one event was sent but two were expected. However,
sending the low-resolution scroll event in the middle plus the existing
heuristics to reset the accumulator solve this issue:
detent detent
| | |
^ ^ ^ ^
REL_WHEEL 112 REL_WHEEL 224
Send low-resolution scroll events in the middle of the detent to solve
this problem.

There do indeed seem to be places in our own code that trigger grabs on
actors before they are realized. It was not the intention to change the
practical preconditions for GNOME 43, so make it an even lower minimum
that every caller ought to match: That the actor is attached to the stage.
Further constraining of these preconditions will have to wait until
branching for new development.

The bare minimum that we can ask to an actor before creating a grab
on it is that it is realized (and thus, attached to the stage). Bail
out if that is not the case when creating a grab.
