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.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1326
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.

As per design discussion, the first page is a somewhat of a special
page where we really don't want to change anything unless necessary.
Append new icons at the first available slot after the first page.
Make the placeholder icon be appended to the first available page
as well, since it's always used when dragging from folder dialogs.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1284
When the app folder dialog handles a drag hover, it starts a timeout
to popdown if dragging outside the "real" dialog area. However, when
dragging inside it, BaseAppView handles all drag hover events which
would disarm the popdown timeout. In cases like this, it's almost
impossible to prevent the timeout from triggering, which always pops
down the dialog.
Add a drag monitor when handling any drag hover (which only happens
when dragging outside the folder's icon grid); and eventually disarm
the popdown timeout from the monitor's motion event. Remove the drag
monitor when dragging over the folder dialog again.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1284
App folders are now customizable, and the way to move icons to
another page is by throwing the cursor to either the left or
the right of the grid.
However, doing that triggers the popdown timeout, wich is 600ms
as of now, which is considerably short for such interaction.
Increase this timeout to 1.5 seconds.

Now that the DnD code is shared between AppDisplay and
FolderView, we hit an unexpected problem: FolderView is
handling drag events even when the folder dialog is hidden.
As a side effect, this spams the journal with warnings.
Only handle drag events when mapped. On unmap, disable
the view's drag monitor, and disconnect from all drag
events.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1284
This code will be shared with FolderView in the next commit, so
avoid duplication already and move the to-be-shared code into the
base class.
Because BaseAppView can handle vertical and horizontal orientations,
adapt the drag overshoot code to also handle horizontal overshoot.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1284
When redisplaying, we currently only remove and add icons, but
never adjust the position of already added icons. If the icon
position changed, it wouldn't be reflected on the icon grid.
Make sure to move already added icons.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1284
It is important that '_loadApps()' return a sorted list -- adding the
same icons at the same positions but in different orders results in
a wrong icon grid.
Add support for using a custom positioning function, and implement it
in AppDisplay. Because FolderView doesn't implement a custom sorting
function, the items are still sorted alphabetically.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1284
The leeways are parts of the icon that ignore incoming drag
events. This is how IconGrid and IconGridLayout treat it, and
this is how the icons should treat themselves too.
Make AppIcon ignore dragging over the left and right leeways.

When using the NVIDIA driver, textures tend to loose their pixels when
suspending. In the past we handled this by figuring out when the NVIDIA
driver was used, and reload the background whenever we noticed we
resumed from suspend.
This shouldn't be needed anymore after
https://gitlab.gnome.org/GNOME/mutter/merge_requests/600, as it should
handle this by listening to video-memory-purged signal. Thus remove our
special handling here.

When using the fade animation when transitioning to the overview instead
of zoom, we fade out all window previews to fully transparent. But after
commit 751189253a removed the old _updateWindowPositions() function,
nothing resets the opacity again, so when switching from the app- to the
window picker, all previews are hidden.
Fix this by always resetting the window preview opacity after showing
or hiding the overview.
https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/2969
We don't animate size and position when fading, so we want all previews
to already be at their final position. However when the app picker is
opened from within the overview, window previews use the zoomed layout,
so that's the state we are then fading when leaving the overview from
the app picker.
Fix that by setting the correct state at the start of the fade transition.
(In the case of fadeToOverview(), the value should always be correct
already, but set it anyway for symmetry with fadeFromOverview())
https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/2969
In commit 9297d87775 we stopped syncing the primary view's actual
geometry at the start of the transition when doing a fade animation,
however the view animation may still be triggered by an allocation
change.
Prevent those unwanted size changes during fade by keeping track of
the fade state and explicitly skip syncing the geometry while a fade
is ongoing.
https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/2969
Since commit af543daf1c, we skip the overview transition when the
actual geometry hasn't been set yet. However with the new layout
manager, the only bit that still needs the separate geometry is
the transition of the view, the workspaces can do their transition
just fine.
https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/2969
When dragging the workspaces through the swipe gesture, all
workspaces must be visible. WorkspacesView's _updateVisibility()
method special-cases this and ensures that.
However, this method is only called when (1) going to the active
workspace, and (2) when the gesture ends. That means, if there
is any workspace hidden by the time a gesture starts, it is never
shown!
Call _updateVisibility() on startTouchGesture() as well.

Because for most frames during a workspace switch it's not changing and
we can repaint it faster if it's cached on the GPU as a single texture.
This seems to reduce the render time for workspace switching by more
than 20%.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1356
When going straight to the app picker, we fade in the overview instead
of doing the full-blown zoom transition. In order to keep windows at
their floating position, we must apply the same to the view itself
and not transition to the overview geometry when fading.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1353
We don't always want to sync the geometry when entering the overview,
namely when the fade transition is used.
However we do want the correct geometry once we have entered the overview,
so that workspaces are at their place when switching from the app picker.
