Since commit 0ecddafc20 gsd-xsettings startup has been made conditional
on the systemd user instance being available at runtime. While that is
correct, it means that completing xwayland startup is also conditional
now.
We always want xwayland startup to go ahead, so wait for the XSettings
plugin to appear on the bus when gsd-xsettings is launched by gnome-session
and complete the task immediately if startup fails.

These paths are meant for Xwayland, not for X11 compositors being restarted
through alt-f2 + r. Maybe some signal analogous to init-xserver should be
added for Xwayland shutdown paths, but this signal we are currently
listening for is backend agnostic.
Closes: https://gitlab.gnome.org/GNOME/gnome-shell/issues/2329
Currently, a failure to start the Systemd unit `gsd-xsettings.target`
would be considered a failure to start Xwayland.
That means that if `gsd-xsettings.target` fails to start for whatever
reason, no X11 client can be used on Wayland.
However, XSettings is by no mean mandatory for X11 clients and many
legacy X11 clients do not implement XSettings. Those who do always have
a fallback path and therefore can still work without XSettings.
Make a failure to start the Systemd unit `gsd-xsettings.target` non
blocking for Xwayland, and just log a warning message.

We do spawn gsd-xsettings, and watch its name before notifying on the
given task, so the mutter bits can proceed with X11 startup.
One notable change is that we only start gsd-xsettings, instead of the
generic gnome-session-x11-services target. We do so as we have to wait
on a dbus name to appear in order to deem the initialization done, and
making it all depend on gsd-xsettings seems tidier.
Less notably, we also use ::shutdown-xserver to shutdown the related
services. Its major benefit is that it'd allow us to ensure the olderly
shutdown of those services, but it's unused at the moment.

When a window is being resized by the compositor, with Wayland the
compositor first asks the window to change its size and emits the
"size-change" signal, and then emits the "size-changed" signal after
the window acknowledges the new size. To show a fancy resize animation,
gnome-shell creates a "screenshot" of the resizing window on the
"size-change" signal, and later animates that "screenshot" to the new
window size on the "size-changed" signal.
Now if a client is not responding to our requests asking it to change
its size, we get a "size-change" signal and start showing the
window-clone, but never a "size-changed" signal, animating and hiding
the clone again. This causes a so called "ghost window" that is shown
above everything else and never disappears again.
To fix that, start showing the window clone once we get the
"size-changed" signal instead of the "size-change" signal. This makes
sure the window actually updates its size and the clone is going to be
hidden again.

This reverts commit c0c027c608. Because for
some reason animating external opacity and position is still incurring
internal repaints, which disables offscreening and makes fading of
overlapping actors look wrong. `ON_IDLE` should be fixed in mutter before
it is used (in boxpointer at least) again.
Fixes https://gitlab.gnome.org/GNOME/gnome-shell/issues/2270
To bypass offscreening in cases where continuous animation is happening.
Offscreening is slower in such cases so this reduces the render time of
animations within offscreenable actors.
On an i7-7700 this reduces the render time of boxpointers for example by
25-30%.

xgettext gained some support for template strings, and no longer
fails when encountering '/' somewhere between backticks.
Unfortunately its support is still buggy as hell, and it is now
silently dropping translatable strings, yay. I hate making the
code worse, but until xgettext really gets its shit together,
the only viable way forward seems to be to not use template
strings in any files listed in POTFILES.

Since ES5, trailing commas in arrays and object literals are valid.
We generally haven't used them so far, but they are actually a good
idea, as they make additions and removals in diffs much cleaner.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/805
ES6 allows to omit property names where they match the name of the
assigned variable, which makes code less redunant and thus cleaner.
We will soon enforce that in our eslint rules, so make sure we use
the shorthand wherever possible.

If an else block only contains an if statement, the two can be
combined into an if-else block, which cuts down on indentation
and usually helps legibility.
There are exceptions (for instance where the outer if and else
blocks are mirrored), but where it makes sense, change the code
to avoid lonely ifs.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/805
Resizing effects are more finicky as other effects, as the actual
animation is delayed until we receive the ::size-changed signal.
However that signal may never be emitted if the window is destroyed
just after starting the size-change effect, in which case the effect
is never completed, blocking mutter from destroying the corresponding
window actor.
Address this by tracking when a resize effect is pending, and complete
the effect when appropriate.

Clutter originally cluttered its namespace with key symbols, before
prefixing all symbols with KEY. We still use the unprefixed symbols
occasionally, replace them so mutter can drop the deprecated symbols.

Every since commit aa394754, StBoxLayout has supported ClutterActor's
expand/align properties in addition to the container-specific child
properties. Given that that's the only container left with a special
child meta, it's time to fully embrace the generic properties (and
eventually remove the child meta).

Remove all transformations from window actors after a window animation
was either cancelled or finished. Right now we only do that if the
transition finished successfully, which seems kind of pointless (it can
probably be historically explained because the callbacks inside the
"kill-window-effects" signal handler are connected to those
`*WindowDone()` functions though and the `*WindowOverwritten()`
functions were only added later in [1]).
This fixes a recent regression where a window animation would get
cancelled and remain stuck by switching workspaces. The regression
probably happened due to different behaviour of the `onOverwritten`
callback of Tweener and the `onStopped` callback of Clutter transitions:
For the workspace-switching animation the window actors get reparented
to a temporary container, which makes Clutter transititons emit
"stopped" (`clutter_actor_remove_child_internal()` stops transitions on
its children), while Tweener would continue the animation.

Remove the `this.actor = ...` and `this.actor._delegate = this` patterns in most
of classes, by inheriting all the actor container classes.
Uses interfaces when needed for making sure that multiple classes will implement
some required methods or to avoid redefining the same code multiple times.

As arrow functions have an implicit return value, an assignment of
this.foo = bar could have been intended as a this.foo === bar
comparison. To catch those errors, we will disallow these kinds
of assignments unless they are marked explicitly by an extra pair
of parentheses.

We now do 2 things along Xwayland startup/shutdown:
- Start or stop the gnome-session-x11-services target, that will
pull all X11 related services that the session might depend on.
- As we start ibus-daemon manually, trigger a restart in order to
toggle the XIM daemon on and off along with Xwayland presence.

Properties that aren't marked as animatable don't support *implicit*
animations, but they can still be animated with explicit transitions.
Use the newly added convenience method to cut down further on Tweener
usage.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/666
The set_brightness() method is the most convenient way of controlling
the effect's brightness, but Clutter animations only deal with properties,
so start using the (ClutterColor) brightness property instead.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/666
Currently WindowDimmer exposes a JS property that is used to control the
underlying effect. This works fine with Tweener, but not with Clutter
animations which we want to use ultimately.
As a first step towards that, expose a setDimmed() method instead of
the property and handle the animation internally, so it can be adapted
more easily.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/666
We now have everything in place to replace Tweener for all animatable
properties with implicit animations, which has the following benefits:
- they run entirely in C, while Tweener requires context switches
to JS each frame
- they are more reliable, as Tweener only detects when an animation
is overwritten with another Tween, while Clutter considers any
property change
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/22
The different units - seconds for Tweener and milliseconds for
timeouts - are not a big issue currently, as there is little
overlap. However this will change when we start using Clutter's
own animation framework (which uses milliseconds as well), in
particular where constants are shared between modules.
In order to prepare for the transition, define all animation times
as milliseconds and adjust them when passing them to Tweener.
