d82dcd6f67 workspace: Don't unfreeze layout during overview animation
During overview closing animation the allocation expands more or less
every frame. Unfreezing the layout then leads to windows snapping to
their new position if e.g. a window was closed which doesn't look nice.

adfcd45bff workspace: Lower maximum window preview size again
In commit 1218e68 we allowed full-sized window previews under the
assumption that we had enough other clues (like the vignette effect)
to differentiate the overview from the regular session.

That didn't hold up in testing, so make the maximum preview size
slightly smaller again.

Adding children to the WorkspaceLayout without calling addPreview() is
not supported, so let's log an error in case that happened.

We also have to allocate that child an empty ClutterActorBox, otherwise

3fb0284358 Make sure to allocate all children in allocate vfuncs
Clutter expects actors overriding the allocate vfunc to allocate all
mapped children of the actor, otherwise bad things happen.

So make sure we actually allocate all our visible children in our custom
allocation functions, and since we don't want to give them a real
allocation, just pass them an empty ClutterActorBox.

It would be nice if we had a way to hide children during the allocation
process where no relayout is queued like gtk allows with
gtk_widget_set_child_visible(), then we could avoid those weird empty
ClutterActorBoxes.

7f402c1c6b workspace: Cap scaled floating size to target layout size
A window preview's floating geometry is scaled down according to the
workspace's allocation, while the layout geometry is computed directly
for the available space.

For previews that maintain their real size in the layout geometry,
that scaling leads to a distracting size bounce when transitioning
between both layouts.

Address that by not allowing the scaled floating size to drop below
that layout size (which is at most equal to the unscaled floating size).

2a0c116757 workspace: Reset window opacity after overview transitions
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.

6cdaec4001 workspace: Always use floating layout for fade transition
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())

751189253a workspace: Use the new WorkspaceLayout for allocating window clones
Switch to the new WorkspaceLayout layout manager to allocate the window
clones of the overview properly using Clutters layouting mechanisms.

Since we now no longer make use of the fullGeometry, we can remove the
setFullGeometry() function from the Workspace class. Also we can stop
setting the actualGeometry on the Workspaces and WorkspaceViews and
instead just set the fixed position and size of the views to their
full or actual geometry. This also has the benefit that we no longer
have to set a custom clip, but can simply enable clip_to_allocation.

The geometry needs to be set inside a BEFORE_REDRAW later because
_updateWorkspacesActualGeometry() is called from a notify::allocation
handler.

This isn't doing any animations when showing/hiding the overview yet,
we'll add that in the next commit.

21187a4cec workspace: Introduce layout manager for allocating the Workspace
Add a new ClutterLayoutManager for layouting the workspaces of the
overview, WorkspaceLayout.

This layout manager integrates the existing LayoutStrategies used to
layout the window clones of the overview and supports freezing the
layout, animating between layout changes and adjusting the spacing for
the width and height of the window chrome. It also adds support for a
layout of the windows that looks the same as the actual workspace,
transitioning between that layout and the LayoutStrategy can be done by
setting the value of an StAdjustment, available using the
stateAdjustment getter function.

This will replace the current static-positioning based layouting of the
window clones in the next commit.

b2c35e4fb0 workspace: Unbreak reposition animation
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
a 0x0 bounding box as size change.

2b4317349f workspace: Set maxChromeWidth to window clone width
So far we allowed the titles of window overlays to expand their width to
be larger than the actual WindowClone, they could expand to the full
size of the Workspace.

Since we're now going to implement those titles as part of the
WindowClone itself, having this feature is no longer possible as easily
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.

of the clone, which makes sure titles never get shown above or

class to the WindowClone class and implement them using
ClutterConstraints instead of the old fixed position/size layout, which
had to be used because the workspaces were scaled, and the title and app

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
