4bc195e797 windowManager: Change unfullscreen mode to NORMAL
The unfullscreen action doesn't make sense in other modes. In the
overview in particular it also prevents clicking on the top bar items on
a workspace with a fullscreen client.

26235bbe54 js: Use (dis)connectObject()
Start using the new methods to simplify signal cleanup. For now,
focus on replacing existing cleanups; in most cases this means
signals connected in the constructor and disconnected on destroy,
but also other cases with a similarly defined lifetime (say: from
show to hide).

This doesn't change signal connections that only exist for a short
time (say: once), handlers that are connected on-demand (say: the
first time a particular method is called), or connections that
aren't tracked (read: disconnected) at all.

We will eventually replace the latter with connectObject() as
well - especially from actor subclasses - but the changeset is
already big enough as-is :-)

2b45a01517 cleanup: Use new indentation style for object literals
We have made good progress on object literals as well, although there
are still a lot that use the old style, given how ubiquitous object
literals are.

But the needed reindentation isn't overly intrusive, as changes are
limited to the object literals themselves (i.e. they don't affect
surrounding code).

And given that object literals account for quite a bit of the remaining
differences between regular and legacy rules, doing the transition now
is still worthwhile.

9069183cec windowManager: Use one consistent animation mode for minimize/unminimize
Firstly don't use EASE_IN for any minimize/unminimize animations because
those start slow and end fast. The effect of that was minimize/unminimize
appearing to be unresponsive to user clicks for a little while before
accelerating away. All such animations should be EASE_OUT for an immediate
response followed by deceleration at the end.

Secondly we replace the shallow 200ms QUADratic curves with a steeper
400ms EXPOnetial curve. Because it's steeper and twice as long the fast part
feels the same as 200ms QUAD, but there's an extra 200ms after that in which
to slow down smoothly giving a more fluid appearance. No sudden stops.

ca1291e418 windowManager: Unminimize a window to its buffer rect geometry
If you slow down the unminimize animation you will notice it overshoots and
then snaps back, but only for decorated windows. Undecorated windows would
unminimize to their correct position. So we remove decorations from the
equation and now all window types unminimize to their correct position.

This wasn't noticeable because the unminimize animation velocity is usually
so high at the end (EASE_IN_EXPO) that there are no frames rendered near the
end of the curve to show it had overshot.

This appears to be consistent with the Mutter source - associating the
actor geometry with `buffer_rect` and not `frame_rect`. See
`meta_window_actor_sync_actor_geometry` for example.

757e766a11 windowManager: Discard workspace scroll smooth events
Since touchpad smooth scroll events with source finger are handled by
the swipeTracker, the workspace scroll handler can focus on discrete
events.

Thanks to Mutter emulating discrete scroll events, see
meta_seat_impl_notify_scroll_continuous_in_impl in meta-seat-impl.c,
it is safe to ignore smooth scroll in the workspace scroll handler
and handle exclusively discrete events.

In addition, once high-resolution scroll events land in Mutter [1], a
mouse will be able generate non emulated smooth scroll events that
should be ignored in favour of the discrete scroll events.
Otherwise, a single mouse wheel click will scroll through multiple
workspaces at once.

8be5d33611 windowManager: Remove timeout on starting X11 services
With Xwayland started on demand, mutter/gnome-shell will spawn Xwayland
and GNOME settings daemon Xsettings.

Currently, gnome-shell uses a timeout of 5 seconds before canceling the
launch and declare failure to start X11 services.

While 5 seconds may seem like a lot of time, when this is executed on a
virtual machine part of a QA tests under load, this causes random
failures.

There is no good value here, we could increase the timeout but it will
always remain racy. Instead, remove the timeout, systemd itself already
has a timeout mechanism (with a much longer wait time).

Thanks to Benjamin Berg <bberg@redhat.com> for finding the root cause
and suggesting the fix.

On systems/setups not using systemd, a failure to start gsd-xsettings
with NOT_SUPPORTED does not denote a failure to start Xwayland, just

Xwayland to start on such systems/setups without systemd.

019229c40e windowManager: Return failure to start X11 services
If for some reason the xserver failed to start, mutter/gnome-shell
should not attempt to connect to the X11 display otherwise it will
lock up in XCB.

An indication of such a premature failure of the xserver is when the X11
services fail to start.

Return the status so that the caller can cancel the connection in time
and avoid the lockup of mutter/gnome-shell in case of failure.

This, however, makes the X11 services a critical component to start
Xwayland, meaning that a failure to start those services for any other
reason than the xserver failing to start would still prevent Xwayland
and therefore X11 clients to run in Wayland. This is however a lesser
issue than mutter/gnome-shell locking up.

This basically reverts commit a96753f0 - "windowManager: X11 can work
without gsd-xsettings".

96dc6d19dd windowManager: Check whether metaWindow is NULL after destroy animation
When logging out or terminating gnome-shell, mutter will unmanage all
open windows, triggering the window-close animation in gnome-shell and
very quickly after that emitting "kill-window-effects". That means we'll
call _destroyWindowDone() to cleanup our animation data, but at this
point the MetaWindow of the window is already gone, so we get an error
that get_meta_window() returns NULL.

4a6f550acb windowManager: Use new mutter API to freeze window actors ourself
We're currently using the hack of telling mutter that our effect is
completed (even though it isn't) in order to unfreeze updates of the
window actor.

This causes a bug with detecting the wl_outputs a window is
visible on, because the MetaWindowActor emits its "effects-completed"
signal too early, making Mutter update the wl_outputs while we're doing
the animation.

Now since meta_wayland_actor_surface_is_on_logical_monitor() uses the
transformed position and size of the MetaSurfaceActor and is being
called right after we setup the animation (but before it actually
starts, that happens at the next paint cycle) it will use a "very wrong"
rectangle: The transformation has been set to move the actor back to its
old position, and while we did already unfreeze updates and called
clutter_actor_set_position() in meta_window_actor_sync_actor_geometry(),
the actual allocation is not updated yet; this makes
clutter_actor_get_transformed_position() return a position including in
the new transformation, but not including the new allocation, and the
rectangle ends up being moved to the next monitor or completely out of
the stage.

To fix this issue properly, we need to decouple unfreezing actor updates
from emitting the "effects-completed" signal, which is now possible with
the new meta_window_actor_freeze() and meta_window_actor_thaw() APIs. So
use those new methods to freeze and thaw actor updates ourselves and
make sure to call shellwm.completed_size_change() only after the
animation has finished.

a96753f085 windowManager: X11 can work without gsd-xsettings
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.

and it was unintended to use here. Restore the usage of
good old MetaDisplay::x11-display-closing.

12e14884ef windowManager: Implement MetaDisplay::init-xserver hook
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.
