Shell.GenericContainer exposes the size negotiation machinery
through the use of signals. Signals are not specially performant.
One of the reasons is that they acquire a global lock for signal
handlers lookup. GNOME Shell has more than 2,000 actors at any
given point in time, up to 20 levels deep in hierarchy, making
size negotiation and painting non-trivial tasks. Such a critical
section of Clutter's machinery shouldn't rely on signals
whatsoever.
Regardless of that, Shell.GenericContainer is a workaround to
a non-existing issue anymore. It shouldn't be used anyway, and
any performance improvements that removing it can potentially
yield are bonuses to it.
This commit starts this work by removing Shell.GenericContainer
usage from Panel.Panel class. The class now extends St.Widget,
and as such, it has no "this.actor" field set anymore. A couple
of places where this actor field was used are adjuste as well.
It is important to notice that we now allocate the Panel itself
inside vfunc_allocate(). This was previously done before emitting
the signal by Shell.GenericContainer.

We show a cover pane on top of the overview during transitions to
prevent issues caused by clicks and mouseover events when the overview
is not ready. Right now, this pane is only being shown on the primary
monitor, which obviosly allows interactions to happen before the
animations are finished on the secondary monitors.
To fix this, use the size of the whole stage for the cover pane.
Remove any usage of MetaScreen, as it has been removed from libmutter
in the API version 3. The corresponding functionality has been moved
into three different places: MetaDisplay, MetaX11Display (for X11
specific functionality) and MetaWorkspaceManager.

We don't toggle the overview if the request happens too close to the
last activation, to filter out double-clicks or activation by both
the hot corner and a click. However as the check is based on the
real time, the check breaks if the system clock moves backwards and
the last activations appears to be in the future. Fix this by using
monotonic time which is guaranteed to only move forward.

When not using arrow notation with anonymous functions, we use Lang.bind()
to bind `this` to named callbacks. However since ES5, this functionality
is already provided by Function.prototype.bind() - in fact, Lang.bind()
itself uses it when no extra arguments are specified. Just use the built-in
function directly where possible, and use arrow notation in the few places
where we pass additional arguments.

These end up emitting item-drag-end/window-drag-end pretty much
without checks. Given the MetaDnd object may end up emitting
::drag-leave as a result of the plugin ending its grab, this
would result on spurious emission of those events and subsequent
warnings.
For extra paranoia, the _inDrag variable has been split into
_inItemDrag/_inWindowDrag so we can't cross the streams.

Don't assume there will always be a primary (logical) monitor, or any
(logical) monitor at all. This includes not allocating / layouting /
styling correctly when being headless.
The initial background loading will also be delayed until there are any
(logical) monitors connected.

Any symbols (including class properties) that should be visible
outside the module it's defined in need to be defined as global.
For now gjs still allows the access for 'const', but get rid of
the warnings spill now by changing it.

Using a MetaWindowActor's shaped texture as the source for window
clones means that if there are further MetaSurfaceActor children
(e.g. a wayland client using sub-surfaces) they don't get cloned.
This obviously wasn't an issue until wayland clients introduced the
possibility of having multiple MetaSurfaceActors under a
MetaWindowActor but there's no fundamental reason we can't clone the
toplevel actor.
WorkspaceThumbnail.WindowClone is the one class that was already using
the MetaWindowActor instead of the texture although it seems to have
been an unintended change in commit
8b99617513.

Commit c39ffa111 moved the signal handling from the controls- to the
background-group to enable scrolling on non-primary monitors.
However this broke scrolling on reactive overview elements as the
workspace switcher, as they're not descendants of the background.
To fix, move scroll-event handling to the overview group itself,
which is the common ancestor of all overview elements.
https://bugzilla.gnome.org/show_bug.cgi?id=768316
Both the Overview::scroll-event and actions added via addAction()
are meant to work anywhere in the overview, but for now only work
on the primary monitor. Move the handling to the background group
that is known to span all outputs to fix.
https://bugzilla.gnome.org/show_bug.cgi?id=766883
The stack was used to overlay a message indicator over the overview
group. That indicator is long gone, so there's no longer a need for
an intermediate actor in the hierarchy.
https://bugzilla.gnome.org/show_bug.cgi?id=766883
The message tray is now empty and about to be removed, so an indication
at the bottom edge of the overview becomes an odd location to convey the
status of the summary. We will eventually display an indication in the
top bar that unseen messages are available, for now just remove the
existing indicator.

_hideDone checks _shown to determine if anything has shown the overview
while we hid it, and if so, shows the overview forward just in case.
In a local patch that called _hideDone immediately inside _hide for
testing, this broke. While we don't actually depend on this anywhere,
it doesn't hurt so that the next person to hack this up (perhaps me!)
doesn't get stuck debugging it for 20 minutes.
It is quite weird to have those calls/signals using WindowClone as an
argument, it is neater to pass MetaWindows around, and have each user
deal with their own representations of these.

The rewrite of Mutter's background code (see bug 735637) requires
corresponding changes here - we no longer need to layer multiple
MetaBackgroundActors together.
The general strategy is that a BackgroundSource object is created
per GSettings schema, and keeps either one Background/MetaBackground pair,
or, for animation, a Background/Metabackground pair for each monitor.

Following design decision, we want to animate AllView and FrequentView
when opening and closing with a swarm spring form.
This involves a few changes needed to allow that, since from some time
now, we are animating page changes in viewSelector, using only a fade
transition. However now we want to let appDisplay and iconGrid apply its
own animation.
For that we special case the change to and from apps page on
viewSelector to let appDisplay to animate its own items, using and API
on appDisplay which at the same time uses an API on iconGrid.
Thanks Florian Müllner for the debugging work

The zooming animation of the windows looks nice when animating
from the workspace display page, but looks weird from other pages
like apps page or search page since the windows come from nowhere
with an initial position not known to the user.
Instead of that just fade the desktop with the windows in its
original position.

The DESKTOP window might not be located at (0,0), in particular
on multi-monitor setups. While we already consider this by setting
the clone's position, we then stuff the clone into a container which
ignores it - meh ...
https://bugzilla.gnome.org/show_bug.cgi?id=723306
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.

Some consumers may want to construct their buttons specially, so allow them
to do that by adding a new API that takes a button instead of a label.

The cover pane is used to block events during transitions, but as
workspaces don't share the same container as other overview elements,
they are currently excempt from the event blocking.
Move the cover pane to the top-level overview container instead.

Moving the mouse fast enough during xdnd will trigger a xdnd-leave event
because the input shape is not updated until after the animation is done.
So simply ignore the leave events while the animation is in progress.

This method, which accepts a .desktop filename, is used to highlight
a specific application in the overview, for example because it has
just been created or installed.

The event catcher that covers the entire primary monitor during
transitions is currently inside a BoxLayout, relying in its
odd support for fixed position actors.
We already have a proper stack widget in place, move it there.

Instead of using the input mode, when the overview is not modal
it should use a Chrome-tracked actor, that is added to the input
region. Because the overview always takes pointer input when
visible, the actor is added at startup, and it is shown and hidden
as needed.

Some keyboard spot a dedicated search key, which gnome-settings-daemon
currently handles by spawning gnome-search-tool. It makes a lot of
sense to promote the Shell's integrated search feature instead, so
expose an appropriate DBus method g-s-d can use.
