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).

It should be allowed to set this._spacing to 0 and thus pass 0 as
rowSpacing or colSpacing to this._adjustSpacingAndPadding(). The current
if-condition there won't add the oversize to the spacing in case 0 is
passed though.
So change that if-condition and explicitely check for null instead.

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,
inclusive, no clipping is applied.

Instead of adding it to the window previews container, add it to Workspace
itself. This requires expanding WorkspaceBackground, so add the relevant
x and y expand flags.
Since the background is beneath the window previews, create and add it before
the window preview container.

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
means it cannot react after being created.
Connect to 'workareas-changed', and update the workarea, the radius bounds,
and relayout when workareas change.

The primary workspace is displayed in the overview, and clipping it
ends up clipping the shadows too. Since Overview's ControlsManager
itself clips to allocation, no windows in the primary monitor spill
to other monitors. However, not clipping non-primary monitors might
end up in situations where their windows spill into the primary one.
Make sure to only clip workspace views of non-primary monitors.

The dialog is shown at session start, which right now means in the
regular session, however the plan is to start the session in the
overview. When that happens, the "Take the Tour" button should get
the user to the Tour without additonal actions.

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().
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1692>
Scaling differently sized WindowPreviews by a constant factor will
result in smaller windows getting enlarged by a smaller amount of pixels
than larger windows (1000*1.02=1020 but 100*1.02=102, one will grow by
20 pixels and the other one by 2), this can look a bit weird because
smaller windows don't scale up as much as larger windows.
So introduce a constant extra size to use when scaling windows up, we
set only the half size there because we want to ensure that the size
added on both sides is not fractional and we remain aligned to the pixel
grid.

Right now the spacing between icon and title works using a little trick
that doesn't really seem intended: The title is offset by
(icon-height * ICON_OVERLAP), when the icon is actually overlapping the
preview by ICON_OVERLAP, and *overflowing* the preview by
(1 - ICON_OVERLAP).
So correct that and offset the title by
(icon-height * (1 - ICON_OVERLAP)), and since now there's no spacing
anymore, add a proper ICON_TITLE_SPACING to that offset.
Also add the new ICON_TITLE_SPACING to the overlapHeight, where the
spacing was ignored so far.

The scale property tracks the relative size at which we display thumbnails
given the space we have available.
That assumes that the allocation represents that available space, but it will
actually be smaller while the minimap itself is collapsing.
Luckily we have an easy option to avoid a distorted scale: Just don't update
it while collapsing. We expect scale changes when adding or removing thumbnails,
but as we freeze those during transitions, we can do the same with the scale.

Right now the minimap only hides itself in case of a single static
workspace. That's not only an edge case, but also not expected to
change while the overview is visible, so changing the visibility
without a transition is fine.
However that is about to change, and we'll hide the minimap as well
when there are fewer than three workspaces. As that condition is
very much expected to change from within the overview, the transition
should be animated.
Implement that via a new :collapse-fraction property on ThumbnailsBox,
and use that to transition both the height of the box itself and the
scale of the individual thumbnails.

We currently have two components that show or hide the minimap:
- the thumbnails hide themselves in case of a single static workspace
- overview controls show the minimap when no search is active
That obviously doesn't work correctly.
To fix this, change thumbnails to set a new :should-show property instead
of the visibility, and let the overview controls take it into account
when changing the visibility.

A small mistake snuck in right before landing the previous commit and
the box-shadow was moved 4px vertically above the wallpaper instead of
below it. Fix that and put it 4px below the wallpaper.

According to the GNOME 40 mockups, add a box-shadow to the workspace
background. For this to work, we also need a background-color (St
limitations), and to make sure that background-color doesn't bleed over
the rounded corners of the wallpaper, we also need to tell St to use a
border-radius and clip the background-color painting using a rounded
path.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1651>
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.

This is the same as the vertical swipe gesture, but for keyboard
junkies: Analoguous to the <super><alt>left/right shortcuts for
switching between workspaces, add <super><alt>up/down to shift

When commit 3a9acb96 moved around padding to extend the clickable
area to the screen edge, it reduced the inner padding too much and
the running indicator ended up outside the highlighted area.
Adjust the padding to put it back into its place.
