This is also exposed in the ShowOSD DBus method, the "monitor"
parameter may contain an integer to indicate the monitor number.
If the value is not provided or <0 is used, the monitor is shown
on the primary monitor as usually.
This way, the OSD can be used to notify upon events that solely
apply to one monitor, like tablet mapping as discussed in
https://bugzilla.gnome.org/show_bug.cgi?id=710373.

You would think we would already do something like this, but apparently
lots of code was calling hide() without checking if the box pointer was
already visible, causing it to queue a full tween. The biggest win was
with ibusCandidatePopup.js, which called hide() on every DBus message.
This increases the performance for me to enter the overview by a tiny
bit. The remaining time is spent updating the frequent apps / all apps
display.

The methods we call in _updateState may not be reentrant, so make
sure that we never get into a situation where _updateState, through
some crazy chain of events, calls itself.

Rather than scanning all apps for searching, use Ryan's new desktop
file index and the glib support APIs for app searching instead of our
own system.

If monitor-changed fires at startup, it will destroy all of the
backgrounds, but since this._isStartup is true, won't recreate any
of them. Additionally, since _bgManagers is indexed by monitor index,
if the primary index is not 0, it could become a sparse array (e.g.
[undefined, undefined, primaryBackground]), and our for loop will
crash trying to access properties of undefined.
Fix both of these issues by always creating background managers for
every monitor, hiding them on startup but only showing them after
the startup animation is complete.
One thing we need to watch out for is that while LayoutManager is
constructing, Main.uiGroup / Main.layoutManager will be undefined,
so addBackgroundMenu will fail. Fix this by passing down the uiGroup
to the background menu code.

If desktop icons are enabled and not covered by maximized windows,
we will fade them in/out during overview transitions. However when
moving background handling into mutter/gnome-shell, we ended up with
the overview background on top of the DESKTOP window clone, hiding
the fade transition.
Fix the stack order to bring the effect back.

Our gnome-shell tweener integration has had hooks to determine when
the tweens have started and completed... except that they had a bug
in them. When a tween completed, it queued an idle handler to run
the callback in. If no tweens were running when the idle was removing,
it reset the tween state that contained the idle handler ID. It also
returned false, meaning that the source would always get removed.
If the actor had a tween in-flight when the idle was fired, it wouldn't
clean up after itself. While this is also a simple bug fix, remove the
callback so we don't queue unnecessary, unused idles.

While unfortunate that we still have to scan all apps with get_all(),
support for this feature will be short-lived, so hopefully we can drop
it in the future as new apps adapt to the desktop file / app ID
recommendations.
For now, simply scan all desktop IDs.

Systemd-for-the-user-session would also do this, but that's a deeply
invasive change that I may not actually get to this cycle. This
change is tiny and non-invasive, but provides an important benefit:
You can actually reliably tell *which* applications are logging which
messages (assuming they're launched by the shell).
This actually complements a recent change in DBus:
See https://bugs.freedesktop.org/show_bug.cgi?id=68559
which does a similar thing for bus activated apps.

Removing an existing source before scheduling a new one is not wrong,
but slightly less effective than doing nothing and relying on the
previously created source to do the job.
https://bugzilla.gnome.org/show_bug.cgi?id=711555
As the handler returns false, the corresponding source is removed
automatically and its id invalidated. Reset the id to 0 to reflect
this, otherwise newer versions of GLib will print a warning when
we later try to remove it explicitly.

There's a potential race condition in the search code: if we have an
outstanding search call to a provider for search "A", and if before it comes
back we do a subsearch for "AB", we won't have any results to pass along.
Previously, we used an empty list when storing the provider results, so we
effectively told the remote search app to filter through this empty list for
any search results that meet the new query, meaning we showed the user 0
results for the provider in this case.
Now that we don't store an empty list, but instead store `undefined`, this race
raises a warning. Solve it by doing an initial search query in this case
instead.
The search code isn't too smart about chained subsearches: now, if we hit this
race while already on a subsearch, we'll do an initial search for the subsearch
query instead, but that is much better than showing the user nothing. This
could be fixed in the future for a performance improvement.

When a notification becomes expanded, it's either already shown,
or in the process of being shown. Don't set the state to SHOWING
again, which confuses our state machine.
The asynchronous nature of extension loading, session loading, and more,
makes the code racy as to what is initialized first, and hard to debug.
Additionally, since gjs is single-threaded, the only code we're running
in a thread anyway is readdir, which is going to be I/O bound, so the
code here is actually likely to be faster.
Drop this in favor of some good old fashioned synchronous loading.
We currently only ensure that width and height are positive, so it
is still possible to pass in values that don't make any sense at all
(which may even result in a crash when exceeding limits imposed by
X11).
There is nothing to screenshot outside the actual screen area, so
restrict the parameters to that.

Rather than create all ShellApps up-front, create them lazily. We really
had no reason to do this before as we were scanning GMenu to get all the
apps, but doing this can remove a need for get_all, which is slow and
memory-hungry.
