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.

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)
Also a couple of bugs are fixed by this:

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.
https://bugzilla.gnome.org/show_bug.cgi?id=785084
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.

The display configuration now exposes a setting to automatically
shift the display color at nighttime. As there are cases where
disabling the filtering temporarily is useful, it makes sense to
expose the feature in the system menu for quick access.
https://bugzilla.gnome.org/show_bug.cgi?id=741224
Some labels in the system status menu - namely network names - are out
of our control, and may thus grow the width "infinitively" unless we
restrict the menu width. So far we have been doing this by setting a
fixed width or max-width, but any value we put there might end up
being too restrictive in some locales. Instead, request a width that
fits all the labels we want to show unellipsized and use that instead
of an arbitrary limit.
https://bugzilla.gnome.org/show_bug.cgi?id=708472
While the GtkSettings::gtk-shell-shows-app-menu property is meant to
reflect a desktop capability (i.e. in the GNOME case: the app menu is
shown in the top bar), it is possible for users to overwrite it.
Respect the setting and actually hide the menu in that case.
https://bugzilla.gnome.org/show_bug.cgi?id=745919
Refer to the system menu in the top bar as "System" rather than "Settings" as
it contains more than just settings and "Settings" is already used for the
settings panel. "System" is also used elsewhere, so include context for
translators.
* switch to a one-column layout (and adjust strings/widths
accordingly
* remove separator before system menu
* add link to account settings to user submenu for consistency

Commit 08690d658f generalized the banner-blocking behavior of the
dateMenu to all menus that would obscure the banner. However setting
up the 'open-state-changed' handler only when an indicator is added
does not work for indicators that change their entire menu (like the
app menu) - we currently end up with menus with no connected signal
handler, and throw an error when trying to disconnect an invalid
signal ID.
To address this, add a new PanelButton::menu-set signal and use that
to set up the 'open-state-changed' handler.
https://bugzilla.gnome.org/show_bug.cgi?id=745910
We currently block banners while the time+date menu is open, as it
would obscure the notification. However it is not necessarily the
only menu for which this is the case, so generalize the behavior
to all menus that would overlap banners when open.
https://bugzilla.gnome.org/show_bug.cgi?id=745910
As notifications appear in the time+date dropdown's message list, there's
a strong relationship between notification banners and the menu. However
while the time+date menu is centered by default, which matches the banner
position, its actual position depends on the session mode - in particular
it is moved to the right in classic mode.
Reinforce the relationship in these cases by moving notification banners
underneath the time+date menu.
https://bugzilla.gnome.org/show_bug.cgi?id=745910
When it comes to keybindings or gestures, there's not really a good
reason why popups associated with the top bar should behave differently
from any other shell menus. Just set the action mode generically for
all menus, so actions like screenshots or media-keys start working
with menus like the background- or app launcher context menus.
https://bugzilla.gnome.org/show_bug.cgi?id=745039
We will soon replace regular menu items in the calendar drop-down
with more complex elements.
However there will still be items that should close the drop down
when activated - rather than making the menu available throughout
the hierarchy (and eventually from outside as well when we add the
notifications list), have a public method on a global object just
like the ubiquitous Main.overview.hide().
https://bugzilla.gnome.org/show_bug.cgi?id=744817
Using a separate property to show when the application is busy rather
than cramming it into the state property makes the code clearer. In most
places we only care if an app is running or not, not whether it is
actually busy.

Both Panel.ActivitiesButton and its parent class Panel.MenuButton would
attempt to connect their own _onEvent() function to Clutter::event,
which counterintuitively was connecting the child class' _onEvent()
function twice.
So, actually chain up on the signal handler, and don't connect twice
to the signal. Both methods were calling this.menu.close(), so only
do that on the parent class handler, since we're chaining up and doing
the right thing now.

Until now the arrows were the associated arrow
character of the font. This cause some problems like
different arrows for different fonts, and size can be
altered because of the font size.
To solve that, use an image for the arrows.

Now that we are indicating 'geolocation in use' to user, we better also
provide at least a way to disable geolocation. Once this is in place, we
can provide slightly better controls rather than simply on/off switch.
