Switching between the app grid and the window picker in the overview via
gestures results in _gestureEnd() getting called with endProgress !== 0
in both cases, which leads to it calling _showDone(). This then
unconditionally changes the state to SHOWN, which in this situation is
already the current state. Since the previous commit this results in a
warning, so check if we are already in the SHOWN state.

There have been several bugs in the past that caused invalid transitions
of the `shown` state, such as going from `showing` to `showing`. These
cause consecutive emissions of the `showing` signal, which can confuse
other classes such as the search controller which connects to the stage
`key-press-event` on showing and disconnects again on `hiding`. Having
two consecutive `showing` signals will cause it to connect twice, and
only disconnect once when hiding the overview again. This will lead to
key presses getting repeated in the search until the session is
restarted. Because there is no obvious connection to how and when this
issue got triggered, this now adds some validation code that only allows
valid transitions and throws an error otherwise so we get a backtrace of
the code actually causing the problem.
This does not fix the issue(s) causing the invalid state transitions, it
only adds a way of tracking them down.

Since commit 7bd98f3f5f the onComplete callback
is called right away when animations are disabled. As side effect, now
this._coverPane gets shown/hidden in the wrong order. Start the animation after
setting this._coverPane initial state, so that the animation callback can set the
this._coverPane final state without it being overwritten later.
Move the animation also after emitting the showing and hiding signals. So that the
order showing -> shown and hiding -> hidden is still preserved when animations are
disabled.

Introduce a new class, EventEmitter, which implements signal
handling for pure JavaScript classes. EventEmitter still
utilizes GJS' addSignalMethods internally.
EventEmitter allows static typechecking to understand the
structure of event-emitting JS classes and makes creating
child classes simpler.
The name 'EventEmitter' mirrors a common name for this pattern
in Node and in JS libraries.

Commit 7419674b changed some grabs from requiring both mouse and
keyboard grabs to be considered successful to only requiring either of
them.
Due to this it was possible for example to open the overview or the
screenshot UI with a client (such as Chrome when opening a menu) holding
the mouse grab. This then made it impossible to interact with the UI
using the mouse (or keyboard) and if attempted could result in an
unresponsive UI.

It existed to fade out/in `nautilus-desktop` for the overview, but it only
ever worked for X11 sessions (`Meta.WindowType.DESKTOP`) and
`nautilus-desktop` no longer exists anyway.
While I had suggested extending it in the past (!1395), that work was
never finished and since then the DING extension has implemented its
own visibility toggling. There seems little value in keeping the old
fade logic around in gnome-shell. Removing it actually fixes a bug with
DING (https://launchpad.net/bugs/1965072).

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.

All callers have been updated to keep this handle to identify their
own grab.
Also, optionally use the windowing state to determine whether
the grab is suitable for the specific uses. This removes the need
to trying to grab twice in the places where we settle for a keyboard
grab.

Destroying the source from an action callback will result in the
notification being destroyed twice:
- source.destroy() destroys all its notifications
- a notification destroys itself after an action
was activated
This results in unwanted log spam when attempting to dispose the
notification for a second time.
There is actually no good reason for destroying the source explicitly,
as sources already self-destruct with their last notification.

The appDisplay used to be accessible via the viewSelector, but
that is gone now. Commit c09c070b15 adjusted the code, but the
replacement uses a Main.overview.appDisplay accessor that never
existed, whoops.
Fix this by exposing a new selectApp() method directly on the
overview, so we don't have to shuffle the appDisplay through
controls → overviewActor → overview.

In the nested session the startup animation sometimes fails, weirdly
that always happens to me when running a freshly built gnome-shell the
first time. The reason it fails is that mutter fails to aquire a pointer
grab from the xserver, XIGrabDevice() is unsuccessful.
A simple workaround for this race condition in the xserver is to just
grab the devices a bit later, that is after the startups animation
instead of before it.
This was also tested with disabled animations, and seems to work just as
well in that case.

Right now we use a ClutterClone ghost of the panel simply to add some
spacing to the top monitor edge.
We can remove the panelGhost by adjusting the allocations of all the
parts of the overview ourselves inside ControlsManagers vfunc_allocate,
this should also work with extensions that move the panel somewhere
else.
This makes the initial relayout of the overview significantly faster,
because we now no longer have to relayout the whole panel in the
process.

When this class was written, all swipes in the shell were vertical, so it
made sense to make the default orientation vertical. This isn't the case
anymore, thus pass make it mandatory to specify orientation when creating
a tracker.
Change the property default values to horizontal as well to match Clutter
instead of the old shell design.

The back → transparent transition gives it a very bad look when
booting and running the startup animation.
Use the same transition duration hack to ensure that the panel
starts completely transparent.

The new startup animation consists of rising the Dash from the bottom,
falling the search entry from the ceiling, and going from HIDDEN to
WINDOW_PICKER with an opacity applied.
One little trick from IconGridLayout was added to ControlsManagerLayout,
which is a promises-based wait for allocation. This is required to make
sure that the transformed position of the search entry is valid, which
is only the case right after an allocation.
This animation also ensures that the overview is shown right on startup.
For session modes that do not have an overview, continue using the same
fade + scale animation.

The property describes the target visibility (that is, the visibility
that will be set after the ongoing transition), and is therefore updated
at the start of the transition rather than from hideDone().
The overview gesture currently misses resetting it at the end, so it
is only updated to the correct state the next time the overview is
entered.

Gestures leaving the overview from a short distance result in an
ugly effect with the panel opacity transitionhaving a fixed duration.

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.

Move AppDisplay, WorkspacesDisplay, and ThumbnailsBox from ViewSelector to
ControlsManager. This allows to always allocate the correct size for AppDisplay,
and will enable for a plethora of further improvements. The end goal is to
completely remove ViewSelector, and let ControlsManager handle the layout of
everything that's visible in the overview.
For now, replace the apps page with a dummy actor in ViewSelector.
Adjust various callers around the codebase to not access the ViewSelector
directly from the overview anymore.
Bind the opacity of the primary workspace to WorkspaceDisplay's opacity. This
allows removing the parent opacity hack in place, which will be done by the
next commit.

Now that Overview is able to ease into any state, be it window
picker or app grid, we can move this ViewSelector method to
Overview itself, which is its rightful place to live.
Remove ViewSelector.showApps(), and make all callers call
Main.overview.show(ControlsState.APP_GRID). Also make sure the
show apps button is correctly toggled.

Boy, does this commit feel good.
While the workspaces view on the primary monitor *appears* as part of
the overall overview hierarchy, this hasn't actually been the case
until now. We synchronized its size and (stage) position to match
the workspaces display, but actually kept in a separate layer for
the transitions to and from the overview.
But now that the new layout manager slides out completely during the
overview transitions, the workspaces display starts out covering the
entire work area, which is exactly what we need for the transition.
So finally stop faking it, and actually make the primary workspaces
view a child of the workspaces display.

there, cascade the calls to OverviewActor, ControlsManager, and finally

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.
So slightly increase the value of SHADE_ANIMATION_TIME to 240 (the
overviews animation time is 250) to make sure those happen in the same
timeframe.

Clutter nowadays omits reallocations when only the stage position
changed, that is when the allocation relative to the parent changed.
As a result (apart from better performance of course), workspaces
in the overview may now end up with an outdated "actual geometry"
in case the overview moved to a new primary monitor (of equal size
as the previous one).
Work around that by emitting a signal from the overview on allocation
changes, and use that to update the cached geometry.
We can revert that change once workspaces become part of the regular
overview hierarchy.

Overview has signals to notify about starting, cancelling, and

Commit c7e597cf72 tried to improve the slide animations when entering
the overview by using the same time as the overall overview animation,
but in fact broke the animation most of the times.
That is because the Overview imports OverviewControls before defining
the ANIMATION_TIME variable, so any javascript code that is evaluated
during that import will see the value as "undefined" (which is converted
to 0 for the animation).
Fix this by moving the ANIMATION_TIME variable before the imports instead
of the usual placement.
