Accessing GObject properties from JS has proven to be quite slow because
of the JS->C->JS roundtrip involved. With the WindowPreview this
actually has an impact since we're accessing those properties very often
while creating new layouts.
So cache the boundingBox and the windowCenter properties of the
WindowPreview using a this._cachedBoundingBox JS object. This might
speed up opening the overview with lots of open windows significantly.

Make computeScaleAndSpace() return an array including scale and space so
we no longer have to access the layout object from outside.
With this we also no longer need to set layout.space, since only the
scale property is needed in computeWindowSlots().
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1617>
Start cleaning up the whole mess around the layout object a bit and
return a new object in the LayoutStrategies computeLayout()
implementation. This object is supposed to be opaque to the API user and
will only be passed to the layout strategy.
For now, keep setting a few things on that object from outside, we'll
clean that up later.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1617>
Only keep computeLayout, computeWindowSlots, computeScaleAndSpace and
the contructor in the superclass, the rest is actually layout specific
and won't apply anymore when we introduce the new vertical layout
strategy.

Move the background to the Workspace class by introducing a new container
called WorkspaceBackground, which handles clipping the background to the
workarea.
Move the click action from WorkspaceDisplay into each workspace.

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.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1609>
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.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1593>
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.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1593>
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.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1593>
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.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1593>
Now that there's only a ACTIVITIES and a SEARCH page, the old method of handling
keyboard tabbing (extra parameters to ViewSelector._addPage()) limits what we can
do.
Manually set up the Ctrl+Alt+Tab support for each element.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1593>
Add them both in a StBoxLayout subclass with a vertical layout. This
new ActivitiesContainer class already contains an adjustment controlling
the transition between workspaces and app grid states, and althought it
is internal to it, it'll be easy to integrate with gestures in the
future.
Notice that AppDisplay is added before WorkspacesDisplay. That's because
we want the paint order to paint WorkspacesDisplay on top of AppDisplay.
Switch the ViewsPage enum to call this page ACTIVITIES, and adjust the
only caller in OverviewControls to it. At last, rename '_appsPage' to
'_activitiesPage' to also reflect the name change.
The usefulness of organizing this code in pages is lost here, but this
is a transitional state, and pages will be removed in future changes.

Only the area used by favorite apps can be used as drop targets, it
is not possible to add new favorites between the running apps at the
end. While that behavior makes sense, it is currently impossible to
distinguish the two areas with confusing results.
Address this by adding a visual separator between favorites and
running apps.

WokspacesDisplay simply remaps the scroll direction into the next
workspace, but that doesn't account for the new horizontal layout.
Scroll horizontally on horizontal layouts when scroll direction is
on the vertical axis.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1603>
The scroll adjustment's upper value corresponds to the number of
workspaces, not to the last workspace index. We want the latter
when mirroring the layout in RTL locales, so subtract 1.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1598>
Now that apps either appear in the dash or the app grid, it makes
sense to allow DND between the two components to add and remove
favorites.
Currently this only works for adding items to the dash, update the
app grid code to also accept drops from the dash.

We use a custom actor to make sure that the show-apps button remains
visible even when there's not enough space to show all icons.
We can achieve the same result with much less code, by using a custom
BoxLayout layout manager for the icons to override the minimum width.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1592>
With the transparent top bar in the overview, constraining to the
primary monitor's workarea causes the (now visible) area beneath
the top bar to not have the darker background, which causes a visual
discontinuity in the layout.
Don't constrain to the primary monitor workarea.

The code previously was using CSS to define row/column spacing and
padding which was combined with a subicon size computed in code relative
to the requested icon size.
In smaller icon sizes it was possible for the CSS spacing+padding + the
size of the two subicons to exceed the requested icon size. This then
would lead to the label being pushed down for app folders compared to
other icons.
Another more severe issue caused by this would happen if the first item
in an icon grid was an app folder. Then the calculation for the maximum
allowed icon size could be off, leading to all icons in the grid
becoming smaller than actually necessary.
This commit changes this to use homogeneous row and column layouts to
evenly distribute the remaining spacing instead of using a fixed CSS
value.
