WorkspaceBackground's allocate is a hot function called every frame
during overview animations. Port it to C.
While we're at it, cache the work area and the monitor geometry, which
do not need to be re-fetched on every allocation.
This reduces the average WorkspaceBackground allocation time from
0.134 ms to 0.017 ms. With four workspaces, scrolling the overview sees
an average WorkspacesView allocation time improvement from
1.104 ms to 0.678 ms.

Commit ba23279f1f was aimed at fixing a
bug where the layout is frozen so early that we don't have an existing
one to re-use, because no allocation cycle happened yet. It tried to fix
that by forcing the creation of a layout when needsLayout === true,
this turned out to be a bit too much, as it also forced creating a new
layout when the layout was frozen after closing a window (which would
set needsLayout to true).
To fix this regression and still avoid reintroducing the bug the
previous commit fixed, tighten the check a bit and only force creating
the new layout when there's no allocation yet. This makes freezing the
layout after closing a window work again.

The transition from the overview freezes the workspace layout at the
start of the animation, which means that the calculated window slots
remain the same while the workspace itslef grows. This causes the
windows to appear slightly shrunk in comparison to the workspace and
shifted to the top left. This is especially noticeable during the
beginning of the animation when there is more weight on the slots than
the original window position and if there are not that many open
windows.
Unfreezing the layout for this transition is not possible, because it
would cause issues with newly opened windows abruptly changing the
layout when the animation happens after starting a new app.
This change instead tries to scale the frozen layout to the current
workspace size. While this is not entirely correct, because this scales
the spacing between the slots as well, it is still more accurate than
the completely unscaled slots.

On some touchpads/laptops, the swipe gesture to open the overview can be
performed so fast, that it starts and ends in between two frames. Now
when this happens, and the gesture ended with too little movement to
confidently say the user intended to open the overview, we'll close the
overview again.
While closing the overview, we freeze the layout of the Workspace in
order to avoid changes to windows messing with the animation. This means
that in the case described above, we freeze the layout even before the
first frame of the opening animation happens. No frames being drawn also
means no allocations happening, and since we create this._layout in
vfunc_allocate(), this means that on the first allocation cycle of the
overview we'll see this._layoutFrozen = true, but will also not have
a this._layout nor this._windowSlots.
This creates an annoying visual glitch where for a split second all
the windows disappear (overview is visible but no WindowPreviews get
allocated).
To fix this, force creating a layout on the first allocation cycle, even
if the layout is currently frozen.

Start using the new methods to simplify signal cleanup. For now,
focus on replacing existing cleanups; in most cases this means
signals connected in the constructor and disconnected on destroy,
but also other cases with a similarly defined lifetime (say: from
show to hide).
This doesn't change signal connections that only exist for a short
time (say: once), handlers that are connected on-demand (say: the
first time a particular method is called), or connections that
aren't tracked (read: disconnected) at all.
We will eventually replace the latter with connectObject() as
well - especially from actor subclasses - but the changeset is
already big enough as-is :-)

We have made good progress on object literals as well, although there
are still a lot that use the old style, given how ubiquitous object
literals are.
But the needed reindentation isn't overly intrusive, as changes are
limited to the object literals themselves (i.e. they don't affect
surrounding code).
And given that object literals account for quite a bit of the remaining
differences between regular and legacy rules, doing the transition now
is still worthwhile.

eee2ccac fixed window opacity being changed outside of transitions but
resulted in the final step of the transition, that would set the window
to fully opaque, being missed.
This change now moves the opacity change entirely out of allocation and
instead follows the adjustment changes directly, which still fixes the
original bug and ensures the opacity is also applied for the last step
in the transition.

On startup desktop-icons-ng Wayland windows have skip-taskbar==FALSE so
initially pass `_isOverviewWindow` and they get added to the overview,
which is confusing to users. However almost immediately after that they
get `meta_wayland_client_hide_from_window_list` and are removed from
future overviews. So now we respond to `notify::skip-taskbar` immediately
and prevent desktop-icons-ng appearing in the startup overview too.
This is messy and ideally we'd like to know the window type immediately
on creation, but that option only exists in X11 and not Wayland.

Dragging a window preview in the overview is supposed to change the
opacity of the dragged actor. This however fails for minimized windows,
because Workspace::allocate() also changes the opacity of those. The
allocation gets triggered by removing the window actor from the
workspace when starting the drag. Avoid this by only changing the
opacity during the overview transitions.

The background group is currently allocated taking care of the workarea
x, y offset but not of its width/height and this may lead to building a
wrongly sized workspace view when the workarea size is not matching the
monitor size (like when there are struts set).
So, take care of the difference between the workarea and monitor
absolute end coordinates to allocate the background scaled content box.

Previously the workarea was only set on construction and then never
updated. As a result the preferred width and height as well as the
allocation were based on an outdated workarea size when it changed after
construction. This for example was happening during the startup
animation, for which the WorkspaceLayout is constructed before the panel
is shown. This caused the workspace in the overview to be slightly
smaller when it is first shown and the overview closing animation to
not expand the workspace to the correct size the first time it is
closed.

We want to clip the Workspace actor in the appGrid state of the overview
in order to make sure windows that overflow the monitor don't spill out.
So far we had commit b1970b95b8 for that.
Now since the last commit, window previews always slightly overflow the
allocation with their icons. That means a part of the window icon gets
clipped away as soon as the transition to the appGrid starts, which
looks weird.
Fix that bug in the transition by slightly extending the clip downwards
when animating between the window picker and the app grid state. The
extra height we extend the clip by is controlled by the overviewState,
which means we extend the clip by the full icon overlap in the window
picker state, but don't extend the clip at all when in the app grid
state.

We want to use as much space as possible for showing window previews in
the overview, and the title and close buttons of those windows are only
visible on hover, so we can show them above anything if we want.
On both primary monitors and secondary monitors, there's a certain free
space available towards the bottom edge of the monitor (on the primary
monitor we show the dash there, and secondary monitors just scale down
the Workspaces). We can make use of this by checking how much free space
there is available from the bottom edge of our allocation to the bottom
edge of the monitor, and then aligning the window previews to make full
use of this space.
So stop adding any padding to the edges of the Workspace, which will
make the windows a lot larger and completely fill the Workspaces
allocation.
The left, top and right monitor edges should always be far enough away
to accomodate the close button and hover scale-up of the window. Only
with the bottom edge of the monitor we have to be a bit more careful
(the overflowing height of the window title is quite big), so there we
check if enough free space is available. If there isn't enough free
space, we simply apply a bit of bottom padding again and shift the
window up.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1813>
Window previews looks slightly offset to the left and top right now
because we don't use the same padding on all edges of the Workspace. We
do that because the oversize and overlap of the window previews is
different on all sides (for example the bottom overlap is very large
because there we show the window title).
To make sure window previews are always perfectly centered on the
Workspace, only use the largest one of the oversize values as spacing
and padding, and add the larger one of the overlap values for the
vertical padding in addition.
With this, we now center the window previews on the Workspace while
never overpainting the allocation of that Workspace to show overlays.

Instead of interpolating our workspace and layout boxes for each child
using clutter_actor_box_interpolate(), use our Util.lerp() function and
stay in JS land instead.
This is quite a large performance improvement since it avoids
heap-allocating a new ClutterActorBox for every child. With this, we're
finally at a duration of 1.0 ms to allocate the Workspace with 20
windows.

It turned out that getting properties and saving them to a variable
outside of loops instead of accessing them everytime inside the loop can
have significant impact on performance, so do that in Workspaces
vfunc_allocate().

that still seems worth it though.

These checks aren't needed since Clutter should enforce this for us

Setting four properties is more expensive than calling two C functions,

We can save a little bit of time in this loop by iterating directly

If the window wasn't in _windowSlots, the index is -1, so the last
element of the array is removed, leading to
https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/3547
I logged the stack trace from removeWindow() and it seems that when you
move the window from the second monitor to another workspace like shown
in https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/3547,
removeWindow() is called twice for it, presumably once for the second
monitor workspace, and then once for the first monitor workspace for
some reason. It is during that call that _windowSlots doesn't contain
the window, so instead the last element (index -1) is removed, leading
to the animation bug.

Instead of always aligning window previews vertically at the bottom of
their row, only do that if we have multiple rows. If there's only a
single row of windows, align every window vertically centered.
This is a very small step towards the new layout for window previews in

changing more is not feasible anymore.

To ensure the workspace thumbnails are vertically closer to the window
picker than to the search, scale down the wallpapers by a fixed number
of pixels. Using 24 px for this means we'll take of 12 px at the top and
12 px at the bottom of the wallpaper, that's a better strategy than
always scaling it by a fixed factor since it doesn't change with the
monitor size.

In the allocate() vfunc of WorkspaceLayout we use a small trick to make
the nonlinear animation paths when opening the overview less jarring:
Because a window might get smaller than its target size during the
animation, we make sure the size never drops below the final size
calculated by the layout strategy.
In the app grid the Workspace is very small though, and the size of a
window slot calculated by the layout strategy might actually be larger
than the workspaceBox. This means we might use the window slot size
instead of the workspaceBox size and end up with a window that's at the
correct position, but its size is too large.
Fix this by only applying this trick when we're animating towards or
from the state where we actually expect the workspaceBox to be larger
than the window slot, that is during the the transition from the session
to the window picker (or the other way round).

Window previews can spill out of the container when their position in the
session overflows the monitor boundaries. In the past, Workspace didn't have
a visible background, and was (almost) always fullscreen, which would mask
this particular problem. However, nowadays, it is very much noticeable when
this situation happens.
Clip the window previews container to its allocation when the overview state
is bigger than WINDOW_PICKER. That is, between HIDDEN and WINDOW_PICKER states,

Currently, Workspace is a single actor that contains both the background,
and all window previews, and is managed by WorkspaceLayout. In the future,
this concentrating aspect of it will bite us; we want the window previews
to be clipped to the allocation, but not the background, since it will
have shadows.
Make Workspace subclass St.Widget with a ClutterBinLayout as layout manager,
and move window previews to a child actor. To reduce the impact of this
extra actor, it's a ClutterActor instead of a StWidget, and the spacing is
still set on Workspace itself.

The WorkspaceBackground class has specific code to clip the background
to the workarea. However, it doesn't monitor for workarea changes, which

Right now the rowSpacing and columSpacing of the layout strategy is
calculated by looking at the overlapping sizes of the close button and
the app icon of the WindowPreview, plus a constant spacing read from CSS
by the WorkspaceLayout that's added to that. We're not factoring in the
extra size of the scaled-up WindowPreviews here and instead depend on
the constant spacing being large enough. If we don't want to depend on
the spacing here, we should add the scaled-up extra size to the sizes
returned by chromeWidths() and chromeHeights().
Since the last commits all previews scale up by the same amount of
pixels, so we can now just add that size to the values returned by
chromeWidths() and chromeHeights().

As planned and shown in the mockups for GNOME 40, round the corners of
the background wallpaper of workspaces.
To do that we use the new rounded-clipping support of
MetaBackgroundContent and we animate the radius by attaching it to the
stateAdjustment just like everything else.
Because we show only a part of the wallpaper and "cut away" the area of
the panel in WorkspaceBackgrounds vfunc_allocate(), we also need to set
the rounded clips bounding rect to the rectangle we're actually showing,
otherwise the texture would be rounded in the region that's cut away.

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.
