This makes it possible to drag a window which appears connected with the
panel, even if it is not in focus. As a result, it should be easier to
manipulate side-by-side windows.

The top bar handles allocating all its children itself, so there's
little value in chaining up to st_widget_allocate() and get the
default layout manager allocating all children again (and possibly
differently).
If this happens, we end up with an infinite allocation cycle with
corresponding performance penalty. Fix this by just doing and what
Shell.GenericContainer did before commit 286ffbe2b6 replaced it,
and not chain up to StWidget.
Thanks to Robert Mader for debugging the issue.

It may not be immediately obvious that the windows section is a
list of open application windows, as titles like "Downloads" can
easily be confused with an action. Add a section heading to avoid
confusion.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/968
We currently copy the app icon menu behavior, which puts a separator
between windows from the current workspace and windows from any other
workspace. It is more useful to have the windows section appear as a
clearly marked group, so drop the separator.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/968
Commit 1b169655ac removed the system indicator from the list of children
that are considered for the overall menu width, because we do want the
log-out submenu to adapt to the available width.
However as a side effect, action buttons no longer contribute to the
width either, so if extensions add additional buttons, the menu is
likely to overflow.
Avoid this by only adding the button group to the list of size children.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/1094
Ouch, this went unnoticed for a long time: As the minimum size of menu
items is generally small (because its label can be ellipsized), we are
requesting the unellipsized width of the last "size child" instead of
the widest one.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/996
If the user's real name is too long to fit the menu comfortably, we are
supposed to use the username instead. However since commit f8e5e3e435,
we no longer set a max-width on the menu as a whole, but instead base
the width request on only "unellipsizable" children. For some reason
the system menu ended up there, so the name is now allowed to grow
indefinitely.
Remove it from the list of size children to get the intended behavior
back.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/400
Window titles aren't restricted in length, so the menu may end up unwieldily
width. Commit 0bec76b6ee therefore limited the app context menus, but that
got accidentally dropped in commit 0ded0dbfd5. Add back the limitation and
extend it to the new app menu as well.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/624
Top bar icons are supposed to by symbolic, but not all applications
provide a symbolic icon. Make the stick out less by desaturating
the appmenu icon if a symbolic style is requested.

Since the plans to retire the app menu were announced, nobody objected to
the removal of the menu content, however some concerns were raised about
the menu's secondary role as indicator.
Account for that by not removing the existing app menu, but replacing it
with a built-in menu similar to the existing app icon context menu.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/624
The GtkSettings was originally introduced to inform applications about
the desktop shell's capabilities, but users soon started to use it to
force GTK+ to show the app menu inside the application. We eventually
caved and also handled the setting ourselves to hide the in-shell app
menu to allow users to "move" it.
But now the remote app menu is in the process of being retired[0], and
will be replaced with a simple indicator that cannot be moved, so
stop following the GtkSetting.

We shouldn't allow toggling menus that aren't supported by the
current session mode, but as indicators are hidden rather than
destroyed on mode switches, it is not enough to check for an
indicator's existence.

Since commit 447bf55e45 we turn the top bar translucent when
free-floating. While this looks fancy and reduces the appearance
of cutting into the available screen space, it has also had a
negative effect on legibility.
Nobody stepped up to address those issues in two years, so revert
back to the fully opaque top bar.

In order to replace GTK+'s GtkDirectionType. It's bit-compatible with it,
too. All callers have been updated to use it.
This is a purely accessory change in terms of X11 Display usage cleanup,
but helps see better what is left.

ES6 finally adds standard class syntax to the language, so we can
replace our custom Lang.Class framework with the new syntax. Any
classes that inherit from GObject will need special treatment,
so limit the port to regular javascript classes for now.

We currently only ignore minimized windows, not windows that are
hidden for other reasons - namely on wayland windows are initially
hidden until they are placed.
This fixes a flicker in the transparent top bar on wayland when the
"position" of an unplaced window wrongly suggests the window is
overlapping the top bar.

Instead of taking care of the PanelMenu.ButtonBox.container
destruction by itself, delegate that to the very object that
created it in the first place: PanelMenu.ButtonBox itself.
In the next commit, we will turn PanelMenu.ButtonBox into a
St.Widget subclass. As a domino effect, PanelMenu.Button will
become one too, and so will Panel.AppMenuButton.
When that happens, the current show() and hide() functions in
Panel.AppMenuButton will clash with Clutter.Actor's ones.
To avoid that, rename these functions to fadeIn() and fadeOut()
and avoid a name clash.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/153
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.

Previously mutter listened to Xsettings (via GTK) to get notified
whether the shell showed the app menu. After X11 support was changed in
the direction of being less central, listening to this particular
Xsettings were removed with the intention of having the Shell tell
mutter directly whether it was showing the menu or not.
This commit makes that happen. It still travels through Xsettings (still
via Gtk), as the shell still gets that state from Xsettings, but fixing
this is out of scope for this particular fix.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/276
Flag some actors that are good candidates for caching in texture memory
(what Clutter calls "offscreen redirect"), thereby mostly eliminating
their repaint overhead.
This isn't exactly groundbreaking, it's how you're meant to use
OpenGL in the first place. But the difficulty is in the design of
Clutter which has some peculiarities making universal caching
inefficient at the moment:
* Repainting an offscreen actor is measurably slower than repainting
the same actor if it was uncached. But only by less than 100%,
so if an actor can avoid changing every frame then caching is usually
more efficient over that timeframe.
* The cached painting from a container typically includes its children,
so you can't cache containers whose children are usually animating at
full frame rate. That results in a performance loss.
This could be remedied in future by Clutter explicitly separating a
container's background painting from its child painting and always
caching the background (as StWidget tries to in some cases already).
So this commit selects just a few areas where caching has been verified
to be beneficial, and many use cases now see their CPU usage halved:
One small window active...... 10% -> 7% (-30%)
...under a panel menu........ 23% -> 9% (-61%)
One maximized window active.. 12% -> 9% (-25%)
...under a panel menu........ 23% -> 11% (-52%)
...under a shell dialog...... 22% -> 12% (-45%)
...in activities overview.... 32% -> 17% (-47%)
(on an i7-7700)

Add an indicator for when there is something access the display server
remotely. This could be 1) remote desktop, 2) screen cast or 3) remote
control, but all effectively applications using
org.freedesktop.portal.ScreenCast or org.gnome.portal.RemoteDesktop as
well as gnome-remote-desktop using the corresponding org.gnome.Mutter
APIs directly.
As it is now, it'll simply show a single icon for when anything is
having an active session, and a single action "Turn off" that'll close
every active session.

Maximized and tiled windows can be restored with a drag gesture,
not only from their titlebars, but also from any non-reactive
parts of the top bar above the window. Currently this only works
for actual pointer devices, extend the behavior to handle touch
as well.

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.

Align and center the date entry with the workspace's workarea.
This way, maximized applications have their window aligned with the top date
entry.
This doesn't change anything for desktops with no docks or when left/right
workareas are aligned with the monitor.
The offset is leftOffset - rightOffset:
(workArea.x - monitor.x) - (monitor.width - ((workArea.x - monitor.x) +
workArea.width))

We will now basically act as "policy provider" for thunderbolt
peripherals by using org.freedesktop.bolt service: when new
devices are connect and session is a unlocked user session
we will automatically enroll (authorize and store in the database)
them.
If new devices are connected but the session is locked a message
will be shown informing the user that the device needs to be
reconnected to properly work.
The org.freedesktop.bolt service is provided by the "bolt" daemon.
The idea behind always showing the icon on the login screen is that
the users' needs aren't known at that point. However we can achieve
the same behavior by including the 'always-show-universal-access-status'
key in GDM's presets, so drop the special-case.
https://bugzilla.gnome.org/show_bug.cgi?id=788943
We are already closing top bar menus on session mode changes, but
as this behavior makes sense for any other menus as well - dash
context menus or the background menu for instance - just generalize
the behavior.

Don't assume there will always be a primary (logical) monitor, or any
(logical) monitor at all. This includes not allocating / layouting /
styling correctly when being headless.
The initial background loading will also be delayed until there are any
(logical) monitors connected.

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.

We need to track the open-status of indicator menus, but don't want
to hook up signals more than once, so we check for the handler ID
we store on the object. As the property is only defined once we did
set up the signal connection, this check now logs a warning. We
can avoid it by checking for the existence of the property rather
than a particular value.
https://bugzilla.gnome.org/show_bug.cgi?id=781471
We currently assume that window state changes are accompanied by an
allocation change (triggered for example by the minimize animation).
However this misses the case where a window actor is simply hidden
without any transition, as is the case with the 'show-desktop' action
for instance, so start tracking plain visibility changes as well.
https://bugzilla.gnome.org/show_bug.cgi?id=783975
The .solid style isn't supposed to apply for modes that don't support
windows, but for this to work we have to update the style on session
mode changes.
https://bugzilla.gnome.org/show_bug.cgi?id=783202
The solid black top bar we currently use works well for maximized
or tiled windows, as it puts focus on the application content by
blending into the monitor bezel. However it also visually reduces
the screen space, which is particularly noticeable when no window
is located nearby. Having the top bar blend with the background is
a better option in that case, so track window positions and add
some transparency when the top bar is free-floating.
