Shell.GenericContainer exposes the size negotiation machinery
through the use of signals. Signals are not specially performant.
One of the reasons is that they acquire a global lock for signal
handlers lookup. GNOME Shell has more than 2,000 actors at any
given point in time, up to 20 levels deep in hierarchy, making
size negotiation and painting non-trivial tasks. Such a critical
section of Clutter's machinery shouldn't rely on signals
whatsoever.
Regardless of that, Shell.GenericContainer is a workaround to
a non-existing issue anymore. It shouldn't be used anyway, and
any performance improvements that removing it can potentially
yield are bonuses to it.
This commit starts this work by removing Shell.GenericContainer
usage from Panel.Panel class. The class now extends St.Widget,
and as such, it has no "this.actor" field set anymore. A couple
of places where this actor field was used are adjuste as well.
It is important to notice that we now allocate the Panel itself
inside vfunc_allocate(). This was previously done before emitting
the signal by Shell.GenericContainer.

Since we always keep the active workspace until the user switches
to a different one, we may end up with two empty workspaces at
the end. It's not obvious to users why this happens, and there's
indeed no good reason for the behavior - just remove the trailing
workspace in that case.

GSettings now recognizes per-desktop overrides that can be used
to change schemas' default values for a particular desktop. This
is not entirely unlike our existing custom override mechanism in
mutter, except that it is not limited to keys in org.gnome.mutter,
and it doesn't require a separate schema - the latter means that
we (and gnome-teak-tool) no longer have to figure out the correct
schema for the current login session and just use the original one.

Commit e5c95b910d refactored the workspace animation to also handle
animations that involve all surrounding workspaces, but due to an
ill-advised review comment (guess whose) it broke the animation
for non-neighboring workspaces.
Update the code to handle correctly whether in a given direction:
- we have the target workspace of a given index
- we have a neighboring workspace
- we don't need to animate anything
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/182
When 4fg swipe motion happens, set up early the workspace switching
animation with all surrounding workspaces. This allows us to move
all content back and forth in any direction. This works on both
touchcreens and touchpads.
When the gesture is activated, the same data is reused to follow
up with the tween animation.
The threshold has been also doubled, it was fairly small to start
with, and feels better now that workspaces stick to fingers.
https://bugzilla.gnome.org/show_bug.cgi?id=788994
Besides the separation into distinct functions, the stored data has
been made able to generically store windows from all surrounding
workspaces. All while keeping a special mode to animate between two
workspaces (The usual till now), this is the only mode exercised so
far.
In order to ease animations, all window groups are now children of
a common container, which is then animated.
Fullscreen windows cannot be restored by touch device users unless the
application adds support for it.
As it is unlikely to change all application lets introduce a top edge
drag gesture which unmakes fullscreen windows.

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.

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.

On the screen shield, the only possible interaction is lifting the
shield. The on-screen-keyboard is not useful for that, and the drag
gesture from the bottom may in fact conflict with dragging up the
shield, so disable it.

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.

The destroy effect currently relies on a monkey-patched property
added from the map effect. However on X11 it is possible that we
did no map animation for a window that is destroyed when the shell
was restarted or had taken over from another WM. Just use the real
MetaWindow property to avoid a warning in that case.
https://bugzilla.gnome.org/show_bug.cgi?id=781471
The fullscreen animation code is now generic enough to handle any
size change animations, so stop limiting it to (un)fullscreen to
get animations on (un)maximize as well.
https://bugzilla.gnome.org/show_bug.cgi?id=766685
Currently, the translation values are set with the assumption that
one of the actors represents a fullscreen window. In order to
generalize it for any size change transition, we can simply swap
the monitor rect with the source or target rect as appropriate,
and translate the actor from the target to the source position by
subtracting the former and adding the latter.
https://bugzilla.gnome.org/show_bug.cgi?id=766685
Since there is already targetRect that represents where the
window is going to move, rename oldRect to sourceRect to
represent from where the window is moving.

GJS implements a basic signal system that allows monkey-patching
JS objects with signal methods resembling the GObject ones. However
it's clearly not a good idea to replace the actual GObject methods,
so use the proper GObject facilities when inheriting from GObject.
https://bugzilla.gnome.org/show_bug.cgi?id=778660
We have no guarantees on the number of ::size-changed signals that we may
receive, so the _sizeChangedWindow handler may run multiple times, which
leads to multiple calls to meta_plugin_size_change_completed(). So double
check the actor is not already being animated in the _sizeChangedWindow
handler to avoid reentrancy.

Wayland clients can request their surfaces to be fullscreened before
commiting a buffer which means that we need to handle fullscreen
requests for which the old size is 0x0, preferably without warnings.
Since the mapping animation also runs for these windows, we can simply
bail out and ignore the fullscreen size change.
https://bugzilla.gnome.org/show_bug.cgi?id=770345
Wayland clients are in control of their window size so the existing
mutter plugin API, which assumes size changes are synchronous, doesn't
work for them since when our size-change handler runs the MetaWindow's
size isn't final yet.
To fix this, the mutter plugin API was extended with a size-changed
vfunc that lets us know when the MetaWindow size has actually
changed. This way we can make the window snapshot and get the old
window size on the existing size-change handler and later, on the new
size-changed handler, get the new size and start the animation.

This is an implementation of the pad OSD that's been previously
present in gnome-settings-daemon. Since things are moving closer
to the compositor, it makes sense to have this implemented as shell
UI.

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
Mutter's plugin destroy event doesn't happen if a window is hidden
when it gets unmanaged so we also need to handle the
MetaWindow::unmanaged signal to check whether the parent should
dimmed.
https://bugzilla.gnome.org/show_bug.cgi?id=752524
meta_window_foreach_transient() iterates through all transients of a
window, not only direct transients. This means that simply checking if
a transient is an attached dialog isn't enough because it might be a
non-direct transient for the window we're checking, in which case we
don't want to dim the window.
In particular this fixes windows not getting undimmed when they have
more that one level of transient children and the direct transient gets
destroyed. In that case we would still find at least one non-direct
transient child and decide to keep the window dimmed.

The various switcher keybindings are handled identically, except for
the popup that is shown; update the code to reflect that instead of
duplicating the code again and again.
https://bugzilla.gnome.org/show_bug.cgi?id=730739
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
Now that we no longer skip dimming/undimming windows while showing
the overview, we can still save a bit of work by changing the dimming
without animation while the window is hidden.
