14d7897a93 style: Stop using braces for single-line arrow functions
Braces are optional for single-line arrow functions, but there's a
subtle difference:
Without braces, the expression is implicitly used as return value; with
braces, the function returns nothing unless there's an explicit return.

We currently reflect that in our style by only omitting braces when the
function is expected to have a return value, but that's not very obvious,
not an important differentiation to make, and not easy to express in an
automatic rule.

So just omit braces consistently as mandated by gjs' coding style.

1398aa6562 style: Fix indentation errors
While we have some style inconsistencies - mostly regarding split lines,
i.e. aligning to the first arguments vs. a four-space indent - there are
a couple of places where the spacing is simply wrong. Fix those.

Spotted by eslint.

55235c2552 style: Avoid trailing commas in array destructuring
When destructuring multiple return values, we often use trailing commas
to indicate that there are additional elements that we are ignoring.

There isn't anything inherently wrong with that, but it's a style that's
too confusing for eslint - on the one hand we require a space after a
comma, on the other hand we require no space before closing brackets.

88697add1b js: Throw GObject.NotImplementedError when requiring overriding
Since version 1.50.0, gjs defines GObject.NotImplementedError for throwing
errors when a "virtual" method that requires a subclass implementation is not
defined.

So use this instead of a generic JS Error in such cases.

3c54e863e6 SwitcherPopup: Check for type using constructor
Classes that are sub-classes of GObject don't use a constructor per se, so we

switcherPopup: Bind to the stage, not the monitor
The switcher popup is a large, mostly transparent actor that
should cover all the clickable area of GNOME Shell. In Clutter
terms, it should cover the whole stage.

By binding it to the primary monitor, the Alt+Tab behavior
becomes a bit inconsistent. For example, by not hiding when
clicking at empty spaces at other monitors.

Fix that by binding the SwitcherPopup to the whole stage,
and not only the primary monitor.

switcherList: Stop using Shell.GenericContainer
This commit removes all the uses of Shell.GenericContainer from
SwitcherPopup.SwitcherList. Compared to the other patches, this
one was specially trickier to get right, and a few invasive
changes needed to be done.

The most noticeable one is that the allocation of the items is
done entirely by St.BoxLayout -- we don't manually allocate them
anymore. To make it work, get_preferred_width() had to calculate
the correct value. It now assumes that:

 * Minimum width: the minimum width of the widest child.
 * Natural width: the minimum width of the StBoxLayout (use it
   instead of the natural width to force the labels to ellipsize
   when too long.)

The AppIcon class became a St.Widget subclass as well, to override
get_preferred_width() and be able to keep the squared shape.

Besides that, add a new SwitcherButton class to reimplement squared
icons without having to resort to hacks in the size allocation
machinery. This class has a single vfunc override to ensure that it
is squared when the SwitcherList is.

The arrows indicating multiple windows are now in this._list
actor to the SwitcherPopup itself, since this._list automatically
manages its own children now.

At last, adapt (but preserve) the hack in CyclerPopup.

switcherPopup: Subclass St.Widget
This commit turns SwitcherPopup.SwitcherPopup into a St.Widget
subclass, and gets rid of Shell.GenericContainer usage. Subclasses
were adapted to that too.

This class introduced a new challenge: it overrides show(). As per
discussions, we now call this.visible = true inside show().

switcherPopup: Rename destroy() to fadeAndDestroy()
In the process of purging all usages of Shell.GenericContainer
of GNOME Shell, one specific problematic situation that might
occur is when classes have functions that would clash with any
ClutterActor or StWidget function name.

One of such example is SwitcherPopup.destroy(). Right now, this
class is a pure JavaScript class that wraps a real actor, but
soon this will change, and it'll become a St.Widget subclass.

Another problem with functions that mimic the toolkit ones is
the predictability of them; after calling destroy(), that widget
is expected to not be available anymore. In SwitcherPopup case,
it is still available for a short while. In this case, that's not
a big problem, but the show() and hide() functions in other clases
are more problematic because the actor's visibility does not
follow that.

This commit is a first step in cleaning that up, and changes the
SwitcherPopup.destroy() to fadeAndDestroy().

4a7082bb0f switcherPopup: Cancel window cycling with Tab
If the Escape key is used for a window/app cycler/switcher shortcut
(such as "Switch windows directly"), then there is no way to cancel
the switching/cycling operation with the keyboard.

This change allows cancelling such an operation by pressing the Tab
key, but only if Tab is not already being used by the current
switcher/cycler shortcut.

3b1330880f cleanup: Use Function.prototype.bind()
When not using arrow notation with anonymous functions, we use Lang.bind()
to bind `this` to named callbacks. However since ES5, this functionality
is already provided by Function.prototype.bind() - in fact, Lang.bind()
itself uses it when no extra arguments are specified. Just use the built-in
function directly where possible, and use arrow notation in the few places
where we pass additional arguments.

06f790d86c switcherPopup: Handle removal of items from SwitcherPopup
This will be mainly useful for closing apps from the applications
switcher, but can be implemented generically enough to select the
nearest existing item after removal if there's any, or destroying
the popup's actor otherwise.

Specifically for the apps switcher, doing this also removes the need
of having to manually either update the current app in AppSwitcher
and highlight it, if there are still any items after the removal, or
simply destroy the AppSwitcher otherwise. Besides, calling _select()
in the handler for item-removed makes sure that the list of thumbnails
in the switcher is always closed, if open, when quitting the app.

c899453800 switcherPopup: Add support for modifier-less keybinding navigation
This drops the requirement that SwitcherPopups need a modifier based
keybinding to work.

The existing behavior for modifier based keybindings is kept but if
the popup is triggered from a no modifiers keybinding, instead of
finishing when the modifier is released, we use a timer that
automatically finishes the popup. The timer is reset on every key
release to allow navigation to happen.

e94de67bd2 switcherPopup: Ignore implicit enter events when the popup is mapped
If the popup happens to be mapped beneath the pointer, mutter will now
emit an implicit enter notify event (i.e. not caused by pointer motion).
In this case the switcherPopup still goes and selects the item, which
results in too sensitive alt-tab menus if the pointer happens to be in
the wrong place.

Make highlighting rely on motion events instead, so it always involves
user interaction when triggered by the pointer.
