Currently, there's one animation for the whole canvas. While it looks fine
with just one screen, it causes windows to move between screens when
switching workspaces. Instead, have a separate animation on each screen,
and sync their progress so that at any given time the progress "fraction"
is the same between all screens. Clip all animations to their screens so
that the windows don't leak to other screens.
If a window is placed between every screen, can end up in multiple
animations, in that case each part is still animated separately.

Currently, the workspace swipe transition only has one workspace in each
direction. This works until you try to do multiple swipes in quick
succession. The second swipe would continue the existing transition, which
only has 2 or 3 workspaces in it, and will hit a wall.
To prevent this, take all workspaces and arrange them into a column or row,
depending on the layout, and use that as a transition.
For the transition that happens when focusing a window on another workspace
(for example, via Alt+Tab), still use only two workspaces instead of all of
them.
Since we don't support layouts other than single rows/columns anymore,
diagonal transitions aren't supported anymore, and will be shown as
horizontal or vertical instead.
Since nw alt-tab and gesture transitions are different, don't allow to do
both at once, that is, disable swipe tracker when a programmatic transition
is going. This will also conveniently cancel a gesture transition if a
programmatic one is initiated while a gesture is in progress.

In future we will need to use window clones to better support multiple
monitors. To avoid having to hide every window, show wallpapers behind
the workspace transition: one per monitor.
Put the wallpaper into a separate class right away, later it will be
useful to make the animation per-monitor.

Simplify the code a bit. The workspace group is relatively self-contained,
so split it from the general animation. Reimplement _syncStacking().
This will help a lot later, with workspace strip and multi-monitor support.

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.

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().

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.

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.

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.
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.
