The appDisplay used to be accessible via the viewSelector, but
that is gone now. Commit c09c070b15 adjusted the code, but the
replacement uses a Main.overview.appDisplay accessor that never
existed, whoops.
Fix this by exposing a new selectApp() method directly on the
overview, so we don't have to shuffle the appDisplay through
controls → overviewActor → overview.

The migration happened in GNOME 3.6 over 9 years ago. The chances
that someone migrates from 3.0.x or 3.2.x to 41 are very much zero.
And if it were to happen, it wouldn't work anyway, because we stopped
using a separate overrides schema.

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.

When a GTK app is started, we create a corresponding GtkApplication
proxy to monitor the app's busy state. If the app is stopped before
the proxy request finishes, we cancel the cancellable before clearing
the running state.
Usually we clear the cancellable once it is no longer needed, namely
when we got the proxy. However when the request was cancelled, the
cancellable has already been cleared, and if there's a cancellable,
it belongs to another request (because the window was added again,
for example when moving between monitors).
Leave that cancellable alone in that case, so we can cancel the
second request as well if necessary to avoid a crash when trying
to set the proxy on a cleared running state.

Right now we pop the modal immediately when closing, so the key-release
event of the Escape key ends up in the focus window which may consume it
for leaving fullscreen mode or similar.
We can avoid that in many cases by keeping the modal grab until the end
of the transition, as the key-release event will then likely occur while
the grab is still in place (provided animations are enabled).

If parsing the pipeline fails for some reason, we currently end up
with a zombie session that leads to a stuck recording indicator in
gnome-shell.
Instead, properly tear down the session to allow mutter and gnome-shell
to correctly update their state.

Not when the main actor dimensions change. So now the shadows don't get
constantly regenerated during the overview animation. In my case this
reduces the render time of the overview animation (tapping Super) by
approximately 10% with 2 windows, or 20% with 10 windows.

Another trivial cleanup. This is in preparation for next commit, that
will expand on this if clause, and will make it a bit more complicated.
Using a variable here makes it easier to read.

Often, when using multiple monitors, the thumbnails box may be
destroyed before the 'hidden' signal of the Overview is emitted,
which leaves a bunch of lingering signal connections to the
workspace manager.
Call this._destroyThumbnails() in the _onDestroy handler, which
disconnects from workspace manager. This fixes the some of the log
spam that GNOME Shell produces with backtraces of destroyed actors.

app_notify_events_added uses an intermediate builder to construct an
array that is then added to the main variant using g_variant_builder_add
which should clear the intermediate, but doesn't due to the way it is
passed: by value, rather than as a pointer.
This was debugged with the help of Eduardo Habkost, who believes it
works on x86 due to big structs being passed as pointers.

On systems/setups not using systemd, a failure to start gsd-xsettings
with NOT_SUPPORTED does not denote a failure to start Xwayland, just
that we're not using systemd.
In that case, we should just ignore the error, otherwise it will prevent
Xwayland to start on such systems/setups without systemd.
Thanks to Rose Kunkel (@rosekunkel) for spotting the issue/suggesting
the fix.

Currently, handling of touch devices in the app grid is a bit awkward,
paging by dragging the view can only happen if started from the gaps
between icons, trying to drag from an icon will trigger DnD, and popping
up the menu takes over it all.
Instead, have the app grid actions play this game of rock-paper-scissors:
- Fast swipes on icons trigger scrolling, beats DnD and menu
- Slower press-and-drag on icons trigger DnD, beats scrolling and menu
- Long press triggers menu, beats scrolling, is beaten by DnD
This allows quick swipes to handle navigation, while still allowing the
fine grained operations. DnD, when triggered, dismisses the menu, if
shown.
This all could probably be nicer with a more stateful gesture framework,
we're not there yet though.

This setting (by default, 0) sets a time threshold in order to allow
DnD. If the drag is shorter than this threshold, DnD will be cancelled,
and event handling left to the next handlers.

We do notify on the ::pressed property after touch begin/end and
recording the event sequence, but we do not return the correct value
if the button was triggered via touch.
Consider the event sequence also in the ::pressed getter, so the
button is considered pressed.

The switcherPopups use _next() and _previous() to get the items
in the text direction. I. e. with LTR _next() gets the right item;
on RTL it gets the left item. This doesn't work well with RTL when using
the arrow keys since the text direction doesn't matter in those cases.
Pressing Left Arrow should still move left regardless of text direction.
So use the opposite methods.

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".

Since commit f60a469a34, everything outside the fade area is painted
fully transparent. That is required for the fade effect during app
grid navigation, to prevent unfaded parts of surrounding pages
becoming visible on wide-screen displays.
However in most other cases, that behavior is the exact opposite
of what we want: Elements outside the fade area (like scroll bars)
should never fade.
In order to fix the regular case, hide the new behavior behind a
property.

Previously the workarea was only set on construction and then never
updated. As a result the preferred width and height as well as the
allocation were based on an outdated workarea size when it changed after
construction. This for example was happening during the startup
animation, for which the WorkspaceLayout is constructed before the panel
is shown. This caused the workspace in the overview to be slightly
smaller when it is first shown and the overview closing animation to
not expand the workspace to the correct size the first time it is
closed.

In the nested session the startup animation sometimes fails, weirdly
that always happens to me when running a freshly built gnome-shell the
first time. The reason it fails is that mutter fails to aquire a pointer
grab from the xserver, XIGrabDevice() is unsuccessful.
A simple workaround for this race condition in the xserver is to just
grab the devices a bit later, that is after the startups animation
instead of before it.
This was also tested with disabled animations, and seems to work just as
well in that case.
