We now found the underlying bug: The ControlsManager (which causes the
bad call to `_updateWorkspacesFullGeometry()`) is getting (re-)allocated
while we add the view to the overviewGroup actor because the
overviewGroup is already visible and the view is immediately getting
mapped by `clutter_actor_add_child_internal()`. That causes a
resource-scale calculation and that indirectly causes a call to
`_clutter_stage_maybe_relayout()` (explained more detailed in the last
commit).
So now that we got rid of the immediate relayout happening when mapping
the view, we can revert this fix.
This reverts commit 6cc19ee6f0.

Animating the window clones of the overview requires the fullGeometry
and the actualGeometry to be set, which they won't be when showing the
overview for the first time. So don't even try to animate the window
clones in that case because the geometries will still be null and
accessing them in workspace.js will throw errors.
The workspace views will still get the correct layout as soon as the
allocations happen because syncing the geometries will trigger updating
the window positions. Since animations are disabled for position changes
when syncing the geometry though, we won't get an animation and the
clones will jump into place. That's not a regression though since before
this change we also didn't animate in that case because the geometries
used were simply wrong (the actualGeometry was 0-sized as explained in
the last commit).
If we wanted to fix the initial animation of the overview, we'd have to
always enable animations of the window clones when syncing geometries,
but that would break the animation of the workspace when hovering the
workspaceThumbnail slider, because right now those animations are "glued
together" using the actualGeometry, so they would get out of sync.
The reason there are no errors happening in workspace.js with the
existing code is that due to a bug in Clutter the fullGeometry of
WorkspacesDisplay gets set very early while mapping the WorkspacesViews
(because the overviews ControlsManager gets an allocation during the
resource scale calculation of a ClutterClone, see
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1181), so it
won't be set to null anymore when calling
WorkspacesView.animateToOverview().
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1119
The fullGeometry and the actualGeometry of the WorkspacesDisplay are set
from the allocation of the overviews ControlsManager and the
WorkspacesDisplay, that means they're only valid after those actors got
their allocations during Clutters allocation cycle.
Since WorkspacesDisplay._updateWorkspacesViews() is already called while
showing/mapping the WorkspacesDisplay, that allocation cycle didn't
happen yet and we end up either setting the geometries of the views to
null (in case of the fullGeometry) or to something wrong (a 0-sized
allocation in case of the actualGeometry).
So avoid setting invalid geometries on the views by initializing both
the fullGeometry and the actualGeometry to null, and then only updating
the geometries of the views after they're set to a correct value.
Note that this means we won't correctly animate the overview the first
time we open it since the animation depends on the geometries being set,
but is being started from show(), which means no allocations have
happened yet. In practice this introduces no regression though since
before this change we simply used incorrect geometries (see the 0-sized
allocation mentioned above) on the initial opening and the animation
didn't work either.

WorkspacesDisplay is a ClutterActor subclass, and overriding
the show and hide methods require chaining up, otherwise the
actor isn't actually shown or hidden.
To avoid clashing with the pre-existing show method, rename
to animateToOverview.

Since a11f417cd0, both drag and scroll
gestures are added to Main.layoutManager.overviewGroup actor, while
previously drag gesture was added to Main.overview._backgroundGroup
instead. Since we cannot use 2 different actors for dragging and scrolling
anymore. just disable the swipe tracker while dragging a window.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/2151
Now that both ThumbnailsBox and WorkspacesDisplay use single adjustments for
controlling indicator and scrolling, create the adjustment in OverviewControls
and pass it to both objects, effectively syncing indicator to scrolling.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/821
Instead of having a scroll adjustment in each WorkspacesView, and using the
one from primary screen in WorkspacesDisplay, have just one adjustment in
WorkspacesDisplay, and sync the changes between WorkspacesView.
This will allow to share the adjustment between WorkspacesDisplay and
ThumbnailsBox in the next commits.

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.

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.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/731
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.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/663
While we aren't using those destructured variables, they are still useful
to document the meaning of those elements. We don't want eslint to keep
warning about them though, so mark them accordingly.

Just as we did for the workspace switcher popup, support workspaces
being laid out in a single row in the window picker.
Note that this takes care of the various workspace switch actions in
the overview (scrolling, panning, touch(pad) gestures) as well as the
switch animation, but not of the overview's workspace switcher component.
There are currently no plans to support other layouts there, as the
component is inherently vertical (in fact, it was the whole reason for
switching the layout in the first place).
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/575
For some reason, people are still seeing those after commit d5ebd8c8.
While this is something we really should figure out, we can work around
the issue by keeping the view actors hidden until the update is complete.

Now that the existing touch/touchpad gestures in windowManager only
handle normal mode, add corresponding gestures for the overview and
hook them up to the existing workspace scroll animations.

ES6 finally adds standard class syntax to the language, so we can
replace our custom Lang.Class framework with the new syntax. Any
classes that inherit from GObject will need special treatment,
so limit the port to regular javascript classes for now.

This attribute was previously only assigned in show(). hide() compares
this attribute to 0. If hide() is called before show() is first called,
the comparison would give the correct result (undefined > 0 is false)
but log a warning:
JS WARNING: [resource:///org/gnome/shell/ui/workspacesView.js 529]:
reference to undefined property "_restackedNotifyId"
Initialize this attribute in _init(), alongside _scrollEventId and
_keyPressEventId which are also used in hide().
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.

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.
