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.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1691>
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.

Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1696>
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.

Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1696>
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.

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
between session, window picker and app grid.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1695>
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.

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
still a reference of it in key press handler.
Given that there's no anymore an active page to redirect input to,
remove these references, so that can be handled in the proper view to
implement key-navigation.

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
icon size using StIcons own icon-size property instead of ClutterActors
width and height property. That ensures the scale factor is applied and
the icon will be properly scaled on hiDPI screens.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1686>
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.
