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.

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().
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/153
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().

Remove any usage of MetaScreen, as it has been removed from libmutter
in the API version 3. The corresponding functionality has been moved
into three different places: MetaDisplay, MetaX11Display (for X11
specific functionality) and MetaWorkspaceManager.
https://bugzilla.gnome.org/show_bug.cgi?id=759538
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.

Similar to what has been done for the apps switcher, this allows closing
windows pressing W or F4 while operating the windows switcher popup or
the apps switcher popup while navigating the list of windows for an app.
https://bugzilla.gnome.org/show_bug.cgi?id=620106
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.
https://bugzilla.gnome.org/show_bug.cgi?id=620106
Make sure that the items from the applications switcher and the windows
switcher are removed when the related applications get stopped, or some
of the associated windows closed.
https://bugzilla.gnome.org/show_bug.cgi?id=620106
Ensure that key-above-tab for selecting window application is consistent
with the down key.
After focus an application in the switcher:
- if you press down, the window thumbnails are previewed, and first element
is selected
- if you press key-above-tab, the window thumbnails are previewed, however
the second element is directly selected.
Make both interactions always select the first element.

Any symbols (including class properties) that should be visible
outside the module it's defined in need to be defined as global.
For now gjs still allows the access for 'const', but get rid of
the warnings spill now by changing it.

Using a MetaWindowActor's shaped texture as the source for window
clones means that if there are further MetaSurfaceActor children
(e.g. a wayland client using sub-surfaces) they don't get cloned.
This obviously wasn't an issue until wayland clients introduced the
possibility of having multiple MetaSurfaceActors under a
MetaWindowActor but there's no fundamental reason we can't clone the
toplevel actor.
WorkspaceThumbnail.WindowClone is the one class that was already using
the MetaWindowActor instead of the texture although it seems to have
been an unintended change in commit
8b99617513.

Similar to bug 667552 for the app switcher, attached modal dialogs
can result in an unexpected window order in the window switcher:
Selecting a window with an attached dialog will focus the dialog
instead, but as the dialog itself is ignored in the window list,
its last-used timestamp is not taken into account for the position
in the MRU list. Fix this by fetching the list of all NORMAL windows
and filter out skip-taskbar windows ourselves, while making sure that
windows appear in the position of their attached modal dialog where
appropriate.
https://bugzilla.gnome.org/show_bug.cgi?id=747153
Similar to windows on another workspace, selecting a minimized window
doesn't look quite right - the selected window disappears, then animates
back in. Fix this by adding support for skipping the next effect to the
wm and use it to bypass the unminimize animation.
https://bugzilla.gnome.org/show_bug.cgi?id=771536
Both 'cycle-group' and 'cycle-window' shortcuts allow cycling through
windows on all workspaces. While this works, it looks quite broken
since we started showing clones for highlighting: the selected window
vanishes (when its clone is destroyed), then slides back in with its
workspace. Instead, slide the selected window to its workspace like
we do for the 'move-to-workspace-*' shortcuts.
https://bugzilla.gnome.org/show_bug.cgi?id=771536
Commit 3171819c improved window cycling by using a dedicated to clone
for highlighting rather than activating all cycled windows. Original
window actors are hidden while its clone is showing, and shown again
afterwards, however the latter is wrong for actors that are not supposed
to be visible (for example where the window is minimized, or on a different
workspace). Fix this by properly syncing the actor's visibility instead
of showing it unconditionally.
https://bugzilla.gnome.org/show_bug.cgi?id=771536
Commit bd6e7f14d1 reimplemented the cycle keybindings to
fix cycling between more than two windows, but the approach
of highlighting cycled windows by actually focusing them has
the drawback that cycling messes up the MRU order of windows.
To fix this, only change the window focus when the operation
finishes, and use a dedicated actor that draws a border around
a window clone for highlighting.
https://bugzilla.gnome.org/show_bug.cgi?id=771063
The code to handle cycling through windows without showing a popup
was removed from mutter a while ago, which left the corresponding
keybindings mostly broken (i.e. they now only switch between two
windows). With the various switch-foo keybindings handled by the
shell, it is now easier to take over the cycle-foo keybindings as
well.
https://bugzilla.gnome.org/show_bug.cgi?id=730739
We are currently erroring out when the tab chain doesn't contain at
least one window for an app which might happen for windows that don't
take focus like xeyes. This leaves us in a state where we can't show
the switcher at all. Let's just ignore these apps instead of looking
broken.
We don't really need this step as a separate method since all
implementations are supposed to be created and shown immediately. This
also ensures that we have items to show in all subclasses.
https://bugzilla.gnome.org/show_bug.cgi?id=735976
All derived classes are already checking explicitly for action names
(FOO and FOO_BACKWARDS). mutter used to have a META_KEY_BINDING_REVERSES
flag for keybindings which required special handling of "shift"+FOO as
FOO_BACKWARDS, but this has been removed now, so this special handling
is no longer necessary.
https://bugzilla.gnome.org/show_bug.cgi?id=732296
Instead of overriding the actor's request with the icon size, just set
the new icon size on the actors, and let the default handler take the
preferred size of children.
https://bugzilla.gnome.org/show_bug.cgi?id=705410
When restricting the switcher popup to the current workspace, we
filter out running apps with an empty window list (namely: no open
windows on the current workspace). However we may end up with an
empty window list even when not restricting items to the current
workspace when all windows of a running app are associated with a
different application via the transient_for hint.
To fix this, just filter out items with an empty window list
unconditionally.

Add an option to limit the appSwitcher to the current workspace. For users
that use workspaces for task separation this more convient then current
behviour. While having to add an option is unfortunate there is no way to make
both groups happy as workspaces usage differes between different users / types
of users.
https://bugzilla.gnome.org/show_bug.cgi?id=703538
Commit 2499f2ed80 went back to using shell_app_activate() for
selecting an app, which favors windows on the current workspace;
this is the behavior we want for instance when activating a
launcher, but it's wrong for the alt-tab list - explicitly
request the first (e.g. MRU) window in that case.
https://bugzilla.gnome.org/show_bug.cgi?id=700356
We chain up on _finish() to drop the grab and destroy the switcher
popup but we should activate the target window first because dropping
the grab results in the previously focused windows getting a focus in
event immediately followed by the focus out event from the target
window activation which we can easily avoid.
https://bugzilla.gnome.org/show_bug.cgi?id=696259
Currently both the app switcher and the thumbnail list divide items
first into two groups (based on whether the item is located on the
current workspace or not), and then sort each group individually
by MRU.
The resulting behavior is often confusing, e.g. when using alt-tab
a second time does not switch back to the original window when the first
invocation involved a workspace switch and the workspace contains
windows of more than one application.
Instead, make the behavior more predictable by sorting both lists
strictly by MRU.
https://bugzilla.gnome.org/show_bug.cgi?id=661156
Now that we use the new 'switch-applications' keybinding for the
application-based alt-tab popup, we can use the 'switch-windows'
keybinding for a more traditional switcher.
Based heavily on the alternate-tab extension from Giovanni Campagna.
https://bugzilla.gnome.org/show_bug.cgi?id=688913
The Shell's alt-tab popup is application-based, so using the
'switch-windows' keybinding for it never really made sense.
Use the newly added 'switch-applications' keybinding instead.
