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
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.

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.

expand new thumbnails before scaling them in.

There are situations where MetaWorkspaceManager and ThumbnailsBox disagree

MetaWorkspaceManager's n-thumbnails property.

ThumbnailsBox currently allocates each workspace thumbnail using their
porthole size, and scales them down using scale-x and scale-y. This is

we want the paint order to paint WorkspacesDisplay on top of AppDisplay.
Switch the ViewsPage enum to call this page ACTIVITIES, and adjust the

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.

The SHADE_ANIMATION_TIME variable sets the duration of the animation of
the background shading that is done when showing the overview. As
explained in the code-comment, that value must be smaller than the
animation time of the overview.
Now since we're going to start animating the background color of the
panel when showing the overview and we're going to use the overviews
animation time for that, we want to make sure the shading of the
background image and the animation of the panel are kept "in sync",
otherwise the transitions would look bad.

overviews animation time is 250) to make sure those happen in the same

The current way of indicating focus of elements in the panel does not
work very well with a fully-transparent panel, a line at the bottom of
the panel doesn't make too much sense if there is no real panel, but
only the text and icons.
To make the indicators look better in this case, switch to a pill-shaped
background color to indicate the focus of items in the panel.
For this to look good, there has to be a small black border above and
below the background, this also requires increasing the height of the
panel (from 1.86em to 2.2em) for visual purposes.
Also, since we now no longer need to color the lower bottom of the

Recent commit [1] added a strong light border around user avatar
icons, in accordance with design mockups.
As a probably unintentional side-effect, the border was also added
around the symbolic fallback icon, which is displayed whenever the
user avatar is not available. This doesn't work well with the current
design, as the strong border makes the subtle fallback icon
background indistinguishable. Additionally, it doesn't match the
design mockups for the symbolic avatar icon [2].
Correct this by adding a style class for when avatar image is used,
and apply the border only for that case.

On some circumstances, however, when the calculated available size

Screen magnification is the compositor's business, not that of "random"

In addition to that, exporting the interface has been broken for an
unknown time, because the object that holds the implementation isn't
referenced and thus ends up being garbage collected, whoops.
And last but not least, this gets rid of the last public D-Bus name
