We have been using type-safe comparisons in new code for quite a while
now, however old code has only been adapted slowly.
Change all the remaining bits to get rid of another legacy style
difference.

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 :-)

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.

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.

`ThumbnailsBox` listens for the `showing` signal from the `Overview` to
create its thumbnails and destroys them on the `hide` signal. Since the
`showing` signal can be emitted multiple times when switching between
the shown and hidden state without ever fully completing the transition,
this will cause `_createThumbnails` to be called multiple times, each
time adding another set of workspaces.

For the primary monitor workspace thumbnail, we must keep the monitor
index in sync with what is currently the primary monitor index,
otherwise we might end up trying to move windows to non-existing
monitors.
For example, if the primary monitor index was 1 when the thumbnail box
was created, but later, the primary monitor index changed to 0, with the
other monitor being turned off, moving a window to one of the workspaces
on the workspace thumbnail, gnome-shell would attempt to move it to the
monitor with the index the primary monitor had in the past, with the
problem being that that monitor no longer exists.
Fix this by listening on the 'monitors-changed' signal on the layout
manager, and update the monitor index of the primary workspace
thumbnails box. Make sure to connect to the signal before creating the
thumbnails box, as the thumbnails box itself will listen to the signal
and recreate its actual thumbnails, and it must do this with the up to
date monitor index.

We block state updates while the indicator for the active workspace
is animating. To track that, we check whether the scroll-adjustment's
value matches the active workspace index. That works as long as the
adjustment's value changes after the active workspace, but not when
switching workspaces via SwipeTracker which only changes the active
workspace after transitioning to the new scroll value.
To fix that, update the indicator on workspace changes as well.

At the moment, we only get the initial :should-show value when populating
the thumbnails. That only happens when entering the overview, so any
listeners to notify::should-show will perceive it as a change rather
than an initialization, which can result in unwanted transitions.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1735>
We currently initialize the porthole to the screen size instead of
the monitor's work area we actually want. At the moment this doesn't
matter, as the minimap is created during initialization with the rest
of the overview, so we can expect a work area change that updates the
porthole to the correct values.
That won't be true for minimaps we put on secondary monitors, so make
sure we initialize the porthole to the actual values.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1735>
The minimap is currently created once when populating the overview,
and kept around until the end of the session. That will change when
we start to also show it on secondary monitors, so do proper clean
up when destroyed.

Since commit 9980c80619, the porthole position is ignored. As a result,
previews are only shown if the primary monitor is located at (0, 0).
To fix this, we either need to propagate the porthole to every thumbnail,
use a custom layout manager that applies an offset to all children, or
add an intermediate actor that offsets the contents.
The last option is the simplest and doesn't require calls into JS on
every allocation, so pick that one.

The scale property tracks the relative size at which we display thumbnails
given the space we have available.
That assumes that the allocation represents that available space, but it will
actually be smaller while the minimap itself is collapsing.
Luckily we have an easy option to avoid a distorted scale: Just don't update
it while collapsing. We expect scale changes when adding or removing thumbnails,
but as we freeze those during transitions, we can do the same with the scale.

Right now the minimap only hides itself in case of a single static
workspace. That's not only an edge case, but also not expected to
change while the overview is visible, so changing the visibility
without a transition is fine.
However that is about to change, and we'll hide the minimap as well
when there are fewer than three workspaces. As that condition is
very much expected to change from within the overview, the transition
should be animated.
Implement that via a new :collapse-fraction property on ThumbnailsBox,
and use that to transition both the height of the box itself and the
scale of the individual thumbnails.

We currently have two components that show or hide the minimap:
- the thumbnails hide themselves in case of a single static workspace
- overview controls show the minimap when no search is active
That obviously doesn't work correctly.
To fix this, change thumbnails to set a new :should-show property instead
of the visibility, and let the overview controls take it into account
when changing the visibility.

We always request a natural width based on the maximum thumbnail scale,
but may very well use a smaller scale when allocating. This currently
results in thumbnails being off center, fix this by distributing any
extra space evenly before allocating thumbnails.

When the original animation was implemented, workspaces would only
ever be added at the end. We therefore got away with not having a
separate EXPANDING stage corresponding to the existing COLLAPSING
one when animating out.
Since support for creating in-between workspaces via DND was added,
this is no longer the case. And now that the thumbnails are centered,
the jump is quite noticeable.
Address this by adding new transitional states, so that we can
expand new thumbnails before scaling them in.

Make the slide property control the workspace scale, so that new workspaces
scale up, and destroyed workspaces scale down. The scale is done horizontally,
and only slightly vertically, as per design direction.
Rework the state tracking mechanism to remove the COLLAPSING state, since there's
no split between sliding out and collapsing anymore. Also remove the corresponding
'collapse-fraction' property from WorkspaceThumbnail.
Make ThumbnailsBox.vfunc_get_preferred_width() consider the slide-position property.

There are situations where MetaWorkspaceManager and ThumbnailsBox disagree
on the number of workspaces, for example when animating them out. It's more
important to follow the visible number of workspaces while they're updated.
Make vfunc_get_preferred_width() and vfunc_get_preferred_height() use the
current number of workspace thumbnails to calculate their sizes, instead of
MetaWorkspaceManager's n-thumbnails property.

ThumbnailsBox currently allocates each workspace thumbnail using their
porthole size, and scales them down using scale-x and scale-y. This is
slightly problematic since it doesn't allow for properly styling these
thumbnails through CSS.
Rework ThumbnailsBox to allocate workspace thumbnails at their actual
sizes, and scale down the '_contents' actor inside WorkspaceThumbnail.

Allocate workspace thumbnails horizontally. This requires introducing code
to handle the RTL direction. Do a small rewrite of the DnD hover method to
be simultaneously simpler and easier to follow, and work correctly on RTL.

This is now all centralized in the apps page, so move the workspaces
thumbnails to ViewSelector's apps page. This allows us to remove
all the slider controls too, since they're now unused.
The transition between showing the workspaces, and the app grid, is
based on the most recent mockups: scale and move it down, and fade it
out.

Clutter expects actors overriding the allocate vfunc to allocate all
mapped children of the actor, otherwise bad things happen.
So make sure we actually allocate all our visible children in our custom
allocation functions, and since we don't want to give them a real
allocation, just pass them an empty ClutterActorBox.
It would be nice if we had a way to hide children during the allocation
process where no relayout is queued like gtk allows with
gtk_widget_set_child_visible(), then we could avoid those weird empty
ClutterActorBoxes.

We can simply get the MetaWindowActor by calling
MetaWindow.get_compositor_private(), so stop accessing the realWindow
property of WindowPreview. For this we also have to make _isMyWindow()
and _isOverviewWindow() take a MetaWindow as an argument instead of a
MetaWindowActor.
Since the WorkspacesThumbnails are also drop targets for WindowPreviews
and their WindowClones also have the public metaWindow property, switch
to using the metaWindow property there, too.

Now that both ThumbnailsBox and WorkspacesDisplay use single adjustments for
controlling indicator and scrolling, create the adjustment in OverviewControls
