aa70020bc8 appDisplay: Compare indicator and grid pages
In the past, the icon grid would update the number of pages
during the call to adaptToSize(). However, after the new grid
layout landed, the number of pages is updated by the time an
item is added or removed.

Instead of comparing the old and new number of pages in the
icon grid, compare the pages shown by the indicator, and the
grid pages.

68203e7091 appDisplay: Allow a slighly bigger area for drag overshoot
Now that we don't have the Frequent tab anymore, and subsequently
the buttons to switch tabs, the app grid fill all the way to the
bottom, leaving no room for drag overshoot.

Add a 20px (i.e. OVERSHOOT_THRESHOLD) area at the bottom of the
grid where dragging actually scrolls to the next page.

cff0752bcc appDisplay: Factor out shared code into BaseAppView
The two BaseAppView subclasses now share a lot in terms of
widgetry: they both have a scroll view, pagination dots, swipe
management, etc.

Move this shared code into BaseAppView. Notice, however, that
BaseAppView only creates the widgetry, but it doesn't add them
to any specific layout. FolderView arranges the widgetry in a
vertical box, while AppDisplay arranges it in a ShellStack.

Add a new 'orientation' parameter to BaseAppView and use it
to determine the orientation of the pagination dots, the swipe
tracker direction, and the scroll event handling.

It is worth noticing that the scroll event is a bit more
sophisticated now: when the orientation is horizontal, it
handles all directions since mice wheels usually only generate
up/down events.

3c3c3b7c69 appDisplay: Don't destroy FolderView directly
When FolderIcon is destroyed, it destroyed the FolderView and, if
there's a folder dialog present, it destroys the dialog as well.

Turns out, the folder dialog adds the icon's FolderView to itself.
The view becomes part of the dialog's actor tree. When the dialog
is destroyed, it also tries to destroy the view - but the folder
view was already destroyed by FolderIcon!

Fix that by letting the dialog destroy the folder view if it exists,
otherwise destroy the folder view directly.

fb4a4ca4a2 appDisplay: Redisplay folders before AppDisplay
When filtering out the app icons, AppDisplay calls FolderIcon.getAppIds(),
which then calls FolderView.getAllItems(). This last function reads the
already added app icons inside the given folder, and return their app ids.

So far, so good.

When the GSettings backing a folder changes, FolderIcon emits 'apps-changed'
to notify AppDisplay that the folder changed.

Cool.

When AppDisplay receives this signal, it first recreates its own icons, then
updates the folders, and finally hides the icons that are inside folders.

This series of events is unfortunate. Future patches will need the folder
to be updated *before* AppDisplay updates its own icons.

Update folder icons before chaining up to BaseAppView._redisplay().

c5dbdad5fc iconGrid: Adapt grid layout according to available size
The new icon grid layout operates based on rows and columns, and
doesn't try to dynamically adapt it to fit to the container. In
this case, it is better to have a pre-defined set of well-known,
well-tested rows and columns, and switch between them based on
the aspect ratio of the screen.

Introduce a set of modes to the icon grid, and select the mode
that is closest to the aspect ratio.

3555550d5e iconGrid: Introduce IconGridLayout
IconGridLayout is a new layout manager that aims to replace the
current paginated layout algorithm implemented by the icon grid.

There are a few outstanding aspects of this new layout manager
that are worth highlighting. IconGridLayout implements all the
mechanisms necessary for a paginated icon grid, but doesn't
implement any policies around it. The reason behind this decision
is that this layout manager will be used by other places (e.g.
the login dialog) that demand different policies to how the
grid should look like.

Another important aspect of this grid is that it does not queue
any relayouts when changing its properties. If a relayout is
required, the actor should manually queue it. This is necessary
to avoid layout loops.

Add the IconGridLayout class. Next commits will do the surgery
to IconGrid and any related code to use this new layout manager.

c23ad83c59 windowManager: Warn when removing old animationInfo
Now that we properly notify mutter about when a size-change animation
has ended, it should never happen that a new size-change animation is
started without the last one being cancelled (ie. 'kill-window-effects'
being emitted).

window actor, so warn in case we still find one when starting the
animation.

4a6f550acb windowManager: Use new mutter API to freeze window actors ourself
We're currently using the hack of telling mutter that our effect is
completed (even though it isn't) in order to unfreeze updates of the
window actor.

This causes a bug with detecting the wl_outputs a window is
visible on, because the MetaWindowActor emits its "effects-completed"
signal too early, making Mutter update the wl_outputs while we're doing
the animation.

Now since meta_wayland_actor_surface_is_on_logical_monitor() uses the
transformed position and size of the MetaSurfaceActor and is being
called right after we setup the animation (but before it actually
starts, that happens at the next paint cycle) it will use a "very wrong"
rectangle: The transformation has been set to move the actor back to its
old position, and while we did already unfreeze updates and called
clutter_actor_set_position() in meta_window_actor_sync_actor_geometry(),
the actual allocation is not updated yet; this makes
clutter_actor_get_transformed_position() return a position including in
the new transformation, but not including the new allocation, and the
rectangle ends up being moved to the next monitor or completely out of
the stage.

To fix this issue properly, we need to decouple unfreezing actor updates
from emitting the "effects-completed" signal, which is now possible with
the new meta_window_actor_freeze() and meta_window_actor_thaw() APIs. So
use those new methods to freeze and thaw actor updates ourselves and
make sure to call shellwm.completed_size_change() only after the
animation has finished.

Commit 1ea22a5281 broke the window reposition animation when it
based the ::size-changed signal on the layout manager's bounding box
instead of the MetaWindow::size-changed signal.

That's happening because of the combination of:

  1. we adjust to window size changes immediately without animations
  2. closing a window triggers a change to a 0x0 bounding box which
     is not treated as a size change

Fix this by addressing the 2nd factor, and don't treat a change to

af543daf1c workspacesView: Only animate on show() when geometries are already set
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().

baeb4079ee workspacesView: Avoid setting invalid geometries on views
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.

Since we're now going to implement those titles as part of the

as it was before. That's because the clones are stacked according to the
stacking of the actual windows, and since the overlay-elements are
attached to those clones, they will also be shown underneath other
clones.

Specifically, this is done by adding the ClutterClones to a static
container owned by the WindowClone and adding the elements of the
overlay as children to the WindowClone itself. That way the
overlay-elements can use the container as a source for their constraints
and we avoid having to make sure the overlays remain visible above the
ClutterClones.

We're not using the new overlays yet, they're hidden by default and
showOverlay() isn't called anywhere yet.
