The animation handling is kinda split between layout (for the
keyboard slide), and keyboard (for the focus window slide). It
would be nice to have more fine grained control on those, so
move the animation handling altogether to keyboard.js as a start.
This is roughly similar, except that transformations apply to
the Keyboard actor, instead of the keyboardBox (its parent). We
now queue a relayout after the animation in order to update the
chrome tracking.
The only layering break now is that we emit
layoutManager::keyboard-visible-changed in keyboard.js, its
purpose will be dropped in future commits, so leave it there for
now.

Gestures leaving the overview from a short distance result in an
ugly effect with the panel opacity transitionhaving a fixed duration.
Make this transition have the same duration (although in a hackish
way) so we avoid the ugly effect.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1643>
The gesture internally manipulates the main adjustment so one swipe
up brings up the overview, and a second swipe up brings the app
grid. The gesture also works in the other direction to get out of
the overview.
Internally, this is delegated on the OverviewControls, so the
adjustment is not leaked out of there. This however meant open
coding the gesture interaction so it can be directed from
overview.js code.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1643>
This will be set whenever an event controller is manipulating the adjustment.
It should enter the same transitional state it does for animations. This
will be used by the overview gesture.

Separate this logic from _switchWorkspaceBegin() and ensure it is set
before this call. The SwipeTracker code uses the orientation to determine
whether the gesture should begin at all, so changing the orientation on
gesture begin was a bit too late.
But also, that meant the SwipeTracker was left at the default orientation,
which was vertical (unlike workspaces, and like the overview gesture).
This made both swipe trackers try to handle the same swipe, with the
WorkspacesView being doubly unfortunate (for triggering in the first place,
and for happening after the other gesture did queue relayouts on it).
Taking this logic outside of _switchWorkspaceBegin() and having the right
orientation beforehand results in both gestures looking for their direction,
and not meddle with each other.

We now have multiple touch swipe gestures with matching fingers and
different directions set on the overview hierarchy. Accepting all
touch swipes without checking the direction makes one of these gestures
take control of input, without other gestures having a say on this.
So, look for the direction of the touch events and look if it matches
the expected orientation before accepting the gesture.

Make the touchpad gesture keep track of its state, and enter in a
rejected state if the swipe is happening in the wrong direction.
Effectively, this means touchpad gestures are locked on a single
direction, and horizontal+vertical swipeTrackers won't be handling
events at the same time.

Some actors don't have the scale applied to them directly but are
children of a scaled parent. In those case just retaining the scale will
not be enough and the scale of the actor itself needs to be adjusted
when reparenting. This could for example be seen when dragging windows
from the workspace thumbnails.

Even if activePage has been removed as part of commit 27627bd40, we've

Given that there's no anymore an active page to redirect input to,

When opening a large number of windows, the computed space and scale for
a layout can become negative due to the per-row/per-column spacing. This
is smaller than the initial values of lastSpace and lastSpace, leading
to a null return which then causes all sorts of other issues resulting
in the workspace becoming invisible.
This change ensures that the function always returns a layout, even if
it may look a bit broken and does not conform to the scale/space
requirements which are impossible to fulfill for the given number of
windows. It's better than displaying nothing, since it allows users to
move/close windows and restore this to a more usable state.

When we got an error, all the other HINT or INFO messages are not useful
anymore and delaying to show them is just a waste of time and may be
even wrong in scenarios with fast authentication devices.
An example are the fingerprint devices, where the user may touch the
sensor repeatedly while we may still show the "touch the sensor" hint
instead of notifying of possible errors.
So, in case we got an error override all the other errors coming from
the same service with lower priority.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1683>
Once the verification has been stopped or has failed all the messages
that are not of error type are just not needed or wrong to show.
For example, in the fingerprint case we may still show the hint to swipe
or touch the device, while the fingerprint PAM service has already been
stopped.
So filter them by adding a new function that adds a null message to the
queue, overriding all the messages that have a lower priority.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1683>
There are cases in which a service may want to override a message with
one coming with higher priority, for example an info or hint message
isn't useful anymore if we've already got an error message.
In the same way when a service has been stopped we don't care anymore
showing its info or hint messages, while it still may be relevant to show
errors.
An example is the fingerprint service that may emit errors quickly while
the hints messages should not be kept around when an error is already
queued or when the service has been stopped.
So, add function that allows to override queued messages based by their
type that follows this policy:
- Messages coming from different services are always preserved in
their original order.
- Messages (from the same service) with a priority equal or higher than
the last queued one are preserved.
- Messages matching completely the last queued are dropped in favor of
this one.

It can be convenient to get the currently showing message in order to
replace or remove it in case it's not needed anymore.
So simplify the message queue handling by only depending on a single
local variable (_messageQueue) and redefining hasPendingMessages
depending on its content.
Now messages are kept in queue till they are not fully processed and the
first message is always the one currently shown.

When a fingerprint failure event happens we may also soon receive a
conversation-stopped event with an error message (such as in the case
we hit the MAXRETRIES value), but this is going to be ignored in case we
are too quick in consider the first failure a verification-failed event
because that implies disconnecting from all the events and then ignoring
such signals.
To prevent this, add a small timeout before failing the verification so
that if we get a further event we will process it.

In the case a service is not available (as it can be in the fingereprint
case when a supported reader is available but has not enrolled prints)
we were trying indefinitely to restart it, however this can lead to
troubles since commit 7a2e629b as when the service conversation was
stopped we had no way to figure out this case and we'd end up to
eventually fail the whole authentication.
However, in such cases the PAM services are expected to return a
PAM_AUTHINFO_UNAVAIL and gdm to handle it, emitting service-unavailable
signal.
So connect to ::service-unavailable and keep track of the unavailable
services so that we can avoid retrying with them.
In case such service is not the foreground one, we can just silently
ignore the error as we did before commit 7a2e629b, without bothering
failing the whole verification.
In case we got a valid error message on service-unavailable, we also
show it, this is normally not happening unless GDM isn't redirecting
here other kind of problems (such as MAXTRIES) which are supposed to
stop the authentication stopping any further retry.

When creating an icon for the system actions search provider, set the

The icon and close button might be overlapping the window actor but
were not considered in has_overlaps() which gets used to decide whether
to offscreen the actor for transparency. Since currently the icon is
visible when the preview is dragged and the whole actor is turned
transparent, the opacity will not be applied to everything as a whole
but the child actors individually. This leads to the window becoming
visible behind the icon.

Calling startTouchGesture() on the workspacesViews can change the
visibility of the workspaces if not all of them are already shown, such
as when there are more than 3 workspaces or for 3 workspaces if we are
not on the central one. This invalidates the allocation and the width
used as distance for the gesture would become 0, resulting in drag
gestures immediately jumping to the first or last workspace due to a
division by 0.

Currently when the foreground service conversation stops we increase the
verification failed count and try to start it again, while if a
background service has been stopped we just ignore it.
This is causing a various number of issues, for example in the case of
the fingerprint authentication service, it is normally configured to die
after a timeout, and we end up never restarting it (while the UI still
keeps showing to the user the message about swipe/touch the device).
So, in such case let's just consider it a "soft" verification failure
that doesn't increase the failures count but will cause us to reset the
UI and try to restart the authentication (and so the affected service).
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1652>
Wiggle may make the error message to be visible for less time so provide
the auth prompt an API to increase the timeout to be used for showing a
message in some cases.
This could be reworked when we'll have a proper asyn wiggle function so
that we could just make the user verifier to "freeze", then await for
the wiggle transition to complete and eventually release the verifier.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1652>
Currently whenever an authentication failure happens we wiggle the
entry, however this may not be related to the service which failed.
For example if the fingerprint authentication failed for whatever reason,
there's no point to wiggle the text input as it's something unrelated to it.
So, only apply the wiggle effect to the entry in case the failure is
coming from the querying service.

Fingerprint PAM module can have multiple failures during a runtime
and we rely on the pam module configuration for the maximum allowed
retries.
However, while that setting should be always followed, we should never
ignore the login-screen's allowed-failures setting that can provide
a lower value.
So, once we have a fingerprint failure let's count it to increase our
internal fail counter, and when we've reached the limit we can emit a
verification-failed signal to our clients.
As per this we need also to ignore any further 'info' messages that we
could receive from the fingerprint service, as it may be configured to
handle more retries than us and they might arrive before we have
cancelled the verification session.

When the login/lock screen is shown the error messages for background
services are always ignored.
However, in case the service is the fingerprint authentication method
we still want to be able to show error messages to inform the user
about what failed, and eventually that the max retries (that may be
different from the login screen configuration) has been reached.
This handles partially the design issue [1] related to the login/lock
screen fingerprint authentication.
Eventually we want to use pam extensions to use clearer and parse-able
messages, however in the case of the fingerprint service we can be sure
that the fprint PAM module will only send errors on auth failures.

Checking whether the item is empty is now the history’s job, per the
previous two commits. The history also trims the input for us.
The effect of this is that we call _history.addItem(), and thereby move
to the end of the history, even if the input is empty (or consists only
of whitespace); clearing the input field and pressing Enter becomes a
quick way to jump back to the end of the history. (The current history
item is not overwritten if the input is empty.)

This ports the runDialog changes of [1] to the underlying history
component, where they can benefit looking glass as well: the history is
now responsible for trimming the input and deciding that it shouldn’t be
stored if empty. (Note that _setPrevItem and _setNextItem already
skipped updating the history if the entry was empty.)
Since both users, runDialog and lookingGlass, also need the trimmed
input for other reasons – runDialog to avoid issues when interpreting
the command as a file path (if it can’t be executed as a command),
lookingGlass to decide whether a command should be run at all – have
addItem return the trimmed input. (runDialog and lookingGlass are not
yet changed to take advantage of this – that will be done in separate
commits.)

When verification failed using a specific authentication service we're
currently restarting the whole user authentication system, which leads
to lots of unneeded operations (reinitializing a new user verifier proxy,
restarting all the gdm workers with the relative PAM modules and so on).
And this makes also debugging of login problems more complicated, given
we're cluttering the journal with repeated data.
However, at reauthentication failure GDM has already set up for us an
user verifier that we can use reuse to start only the service that had a
failure. So when possible, just start a new service instead of rebooting
the whole authorization process.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1622>
When retrying the authentication we should make sure that all the
previously initiated services are stopped in order to begin a new
authentication session with all the configured services.
Unfortunately at the current state we only dispose the currently used
user verifier, but we don't make it to stop all the relative gdm workers
and then they'll stay around potentially blocking any further usage of
them (as it happens with the fingerprint one, that has unique access to
the device).
So, cancel the currently running authentication before starting a new
one if we're explicitly retrying.

When a verification session has failed we may want to wait for the user
to have completed all the waiting queries and to have read all the
incoming messages, however during such time an user verifier should
not be allowed to queue further messages to the UI, as we're about to
completely stop the identification or start a new one.
Unfortunately this is not true because we're still connected to the
identifier signals, and so we may still show messages.
This is particularly true when using the fingerprint PAM module as it
may restart the authentication while we're in the process of stopping
it.
So, keep track of all the signals we've connected to, and disconnect on
verification failed and during cancel/clear operations.

As per previous commit the user can cancel an ongoing authentication via
Escape key and that will always send the user back to the clock view in
lockscreen or user-selection view in login prompt.
However, we can be a little more permissive and don't switch view to be
able to restart the authentication without further action.
To avoid this to be abused though, we consider the user verification
cancellation via escape key to be a "soft-failure", so once the
configured "allowed-failures" gsettings value has been reached, we'd
just act as before, ignoring any further request (until we don't get
back to the user auth view).
In this way we still make brute-force attacks harder to do, while still
giving the well-behaving user some ability to fix mistakes.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1622>
Escape key is supposed to cancel a verification, however if the user
already hit Enter to begin the authentication the Escape key won't work
until the verification completed.
This may be quite inconvenient when an user did a typo while writing and
wants to cancel the already started auth.
So, while authenticating (or in general while the entry is unsensitive)
give the key focus to the authpromt itself so that we can still get the
input events and cancel an user action.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1622>
When a cancel event in the user lockscreen happens we first emit a reset
signal and immediately a cancelled one.
This lead to start a new gdm worker for each enabled authentication
method and then immediately to stop it.
As per the previous commit, we don't have anymore dangling gdm workers
around, but still we should not even start a new one in such case.
So, when the user explicitly cancelled the authentication session, first
emit a cancelled event and only emit a reset event with a begin request
if we are outside the lockscreen.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1622>
When we cancel an user authentication via Escape key or cancel button on
AuthPrompt we reset the view and we emit a 'cancelled' signal that leads
to destroying the auth prompt and the user verifier.
However, the verifier may still have an operation in progress and its
completion may take some time (as in the case of gdm-fingerprint), but
we just leave the gdm worker running until its pam module completes
(potentially never) clearing and disposing its handle.
So, instead of just clearing the verify, actually cancel and clear it.
In case the user verifier is set, clearing the relevant data will happen
anyway as part of the cancel() call.
Ideally this would have been handled by gdm itself, but unfortunately we
can't fix it there because the verifier itself is a class generated by
gdbus-codegen, so we can't handle this automatically on disposal nor we
can automatically monitor when the caller proxy is stopped on our side.

The behavior of workspaces is different depending on whether
the overview is in window picker state, or app grid state.
When in window picker state, clicking on adjacent workspaces
should only activate them, without hiding the overview; and
clicking on the active workspace hides the overview. When in
app grid state, clicking on a workspace must always hide the
overview.
Pass the overview adjustment to Workspace, and leave overview

The overview transition consists of getting the initial and final
states of the overview adjustment, derivating various other internal
states from them (such as the fit mode, opacities, translations, etc),
and finally interpolating the allocation boxes.
When interpolating between the fit mode, WorkspacesView uses the current
allocation box to derivate the SINGLE and ALL fit mode boxes. However,
that creates a curved path during overview transitions. What we really
want to do here is calculate the fit mode box relative to the corresponding
overview state. For example:
+----------------+----------+------------------------+
| Overview State | Fit Mode | Workspaces geometry |
+----------------+----------+------------------------+
| HIDDEN | SINGLE | Cover entire screen |
| WINDOW PICKER | SINGLE | Between minimap & Dash |
| APP GRID | ALL | 15% screen height |
+----------------+----------+------------------------+
Using the table above as the reference, when the overview transitions
between WINDOW PICKER and APP GRID, we must interpolate between
(SINGLE fit mode @ between minimap & Dash) and (ALL fit mode @ 15% screen
height). That way, we always interpolate the final boxes, which corrects
the odd path that workspaces follow during this transition.
Make the WorkspacesView of the primary monitor use these cached boxes
when the overview is in the middle of a transition, and the fit modes of
the initial and final state differ, to calculate the workspaces positions.

WorkspacesView uses the floating layout when the overview is in window
picker mode, and the session layout when the overview is in app grid
mode. Up until now, the fit mode adjustment was used to derive the
workspace mode, but it is incomplete as it doesn't have the full range
of workspace states.
Make ViewSelector cascade the overview adjustment to WorkspacesDisplay,
and use the overview adjustment itself to derive the workspace mode.
Extra workspaces don't have to account for the fit mode, and thus are
basically a clamp(state, 0, 1) of the overview state. However, don't
call animateTo/FromOverview() anymore, since they ease the workspace
mode adjustment.

Boy, does this commit feel good.
While the workspaces view on the primary monitor *appears* as part of
the overall overview hierarchy, this hasn't actually been the case
until now. We synchronized its size and (stage) position to match
the workspaces display, but actually kept in a separate layer for
the transitions to and from the overview.
But now that the new layout manager slides out completely during the
overview transitions, the workspaces display starts out covering the
entire work area, which is exactly what we need for the transition.
So finally stop faking it, and actually make the primary workspaces
view a child of the workspaces display.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1624>
Instead of delegating it to ViewSelector, make the transition to and from
overview ease the main state adjustment.
This commit temporarily breaks these animations, but on the other hand
introduces an important feature: ViewSelector is always allocated to the
actual size. This will finally allow for adding WorkspacesView as a child
of WorkspacesDisplay, and finally remove the actual geometry hack, which
is what next commit is about.
This commit also effectively reverts b64103efc.

Currently, ActivitiesContainer reacts to showAppsButton and
transitions between app grid and window picking states on
its own. In the future, we want full control over this.
ControlsManager already has a state adjustment that represents
all possible overview states. Propagate this adjustment up to
ActivitiesContainer, and use it to drive the transition.
This requires moving the callback to the showAppsButton to
ControlsManager, since now it control the state adjustment
itself, not ActivitiesContainer's adjustment.

In the future, we want to tightly control the state of the

Currently, gnome-shell uses the wrong scrolling direction for
horizontal scrolling events.
When dx < 0 for a smooth scroll event, then the scrolling direction is
supposed to be Clutter.ScrollDirection.LEFT, instead of
Clutter.ScrollDirection.RIGHT, as dx is smaller than 0.
Fix this issue by swapping the values LEFT and RIGHT.

It is possible for an initiated session to complete without
a request if polkit can authenticate the action without user
input. We fail to clean up after ourselves in that case, as
the cleanup is done after the dialog is closed.
The dialog can still be shown when the code that hides existing
dialogs while the screen is locked shows it on unlock. But as
the session was closed, the dialog is now defunct and cannot
be dismissed by the user.
Fix this by running the cleanup on close() when the dialog
wasn't shown.

Previously we used a bunch of heuristics for this. We checked if velocity
was directed towards the nearest snap point and its value was larger than
a threshold. If it is, we completed the swipe, otherwise we cancelled it.
This was good enough at the time, because this code was originally written
for back/forward swipe. Since then, the swipe tracker was extended to
handle arbitrary snap points and not just 0 and 1, or -1 and 0, depending
on text direction. After that it was iterated on, but never significantly
redone.
This worked well enough, but had two problems:
1. In some cases, notably overview, it may be wanted to be able to swipe
through multiple pages at once. This wasn't really possible because we
always picked the adjacent snap point.
2. Since we can't do that well, we want to restrict swipes to one page at a
time. It was done in a rather hacky way by clamping the position into
[-1, 1] range from the place where we started the swipe. This works
if we start the swipe from idle position, but if an animation was
already going, the range would be clamped to arbitrary values, and very
likely containing only one snap point, which we already swiped past at
this point. In this case, finishing the swipe would cancel it regardless
of velocity. This means that if one tries to quickly move through
carousel pages via swiping, half of the swipes will be inexplicably
cancelled.
We'll use the deceleration formula from
https://medium.com/@esskeetit/how-uiscrollview-works-e418adc47060#10ce
to calculate then projection point, then pick the nearest snap point and
calculate the duration as we did before. It works well enough for short
distances, but has two problems:
1. It caps the maximum distance at a pretty low value - about 5 pages in my
testing.
2. With how we pick the nearest snap point, it's too easy to accidentally
cancel the swipe,
To combat the first problem, we can modify the curve: only use linear
function at small distances, and smoothly transition it to a parabola
further.
For the second problem we can add two special cases: first, if the swipe
ended up between the initial snap point and the next one, we always prefer
the latter. Second, a good old velocity threshold for cancelling.
We'll also use a slightly smaller deceleration value for touchpad: 0.997
instead of 0.998.
Now that we can pick any snap point, the [-1, 1] clamping doesn't make
sense anymore, so instead let's replace it with a more flexible
mechanism: if we're near a snap point, pick its adjacent snap points.
Otherwise, take the two nearest snap points, and take their adjacent
snap points. This way we have 3 snap points to choose from when
starting a swipe from an idle position, and 4 if we start during an
ongoing transition.
This way, if we've just swiped from snap point n to n+1, the transition
will pick snap points n-1, n, n+1, n+2 and if we swipe again, we will
likely land on n+2. During that transition, if we swipe again, it will
likely have already passed the snap point n+1, so this time the available
snap points will be n, n+1, n+2, n+3, so we can swipe again and it will
still complete, and so on.
This will make it easy to allow multi-page swipes as well, by just
removing the clamping.

In some cases we may get anevent with very low delta at the end of the
swipe. While we can't completely ignore them, we can smooth them using a
scroll history, similarly to what GTK kinetic scrolling does: keep track
of the last 150ms of events, and sum their deltas when calculating the
velocity.
The logic is based on what GTK does in GtkGestureSwipe and
GtkEventControllerScroll.

Let empty input result in an error, just like other invalid commands
(bad syntax, nonempty whitespace, etc.). GLib already has an error
message “Text was empty (or contained only whitespace)” which it shows
for whitespace-only input, so letting that message apply also to empty
input makes sense.
This requires some tweaks further down the file to avoid interpreting
empty input as an empty path (relative to the home directory) and then
opening the home directory.

The Message class this is derived from unconditionally adds a close

So far, we couldn't allow workspace scrolling outside the overview
because scroll events were always sent to clients. However mutter
was changed recently to pass on scroll events when the mouse button

The code to update the actor position based on the cursor and current
scale was run in a 'new-frame' handler. This is working fine when
animations are enabled, but when they are turned off this does not work.
This is because the 'new-frame' signal is emitted before the changes for
that frame are applied. So with animations off the position was only
ever updated with the starting values. As a result the shrunk actor was
not being dragged by the position where it was clicked, but by where it
was clicked in the original size, which is likely not even on the shrunk
actor.
This change now also updates the position in the onComplete handler
which gets run with the final scale, even if the duration is 0.

When vertically snapping, WorkspacesView currently allocates workspaces
side-by-side, then applies an extra step of translation to center to
the active workspace. This extra step, however, gets in our way because
now we need tighter control of the workspaces positions in allocation,
in order to properly interpolate them.
Move the translation of workspaces to the allocation code itself, and
remove the extra translation step.

Currently, WorkspacesView positions each workspace on a
per-page layout, each page with the allocated width and
height of WorkspaceView. This layout doesn't work well
with horizontal workspaces.
Layout workspaces side by side, instead of per page. The
layout is influenced by a "fit mode", which reflects the
different behaviors exposed in the mockup. This fit mode
represents whether a single or all workspaces will fit
available geometry.
The single fit mode is always used for now. Next commits
will make it switch to the all fit mode when in the app
grid state.
The translation_{x,y} also needed to reflect the switch to
a side-by-side layout, and use the geometry of the workspaces
to determine the offset. Notice that, when the fit mode is ALL,
there's no translation applied.

The new window preview overlay requires getting the app icon for a
window from the window tracker when it gets initialized. The window
tracker listens for the same 'window-added' signal on the MetaWorkspace
that the gnome-shell Workspace listens for to add the window preview.
The window tracker however reconnects all its signal handlers whenever
the number of workspaces changes, which means that its signal handlers
get called after the ones in Workspace ones. So by the time the
'window-added' handler in Workspace is called, the window tracker does
not have an app associated with the window.
To fix this ensure that all window related signal handlers in Workspace
are run after the ones in the window tracker.

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

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.

Accessing GObject properties from JS has proven to be quite slow because

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.
