The different units - seconds for Tweener and milliseconds for
timeouts - are not a big issue currently, as there is little
overlap. However this will change when we start using Clutter's
own animation framework (which uses milliseconds as well), in
particular where constants are shared between modules.
In order to prepare for the transition, define all animation times
as milliseconds and adjust them when passing them to Tweener.

Those unused arguments aren't bugs - unbeknownst to eslint, they all
correspond to valid signal parameters - but they don't contribute
anything to clarity, so just remove them anyway.

This was left-over in commit 2743f18af, and probably is the real reason
why the busy spinner wasn't using the shared AnimatedIcon.Spinner class:
The animation there was much slower.
Still, let's keep the code as-is for now, if we really need a different
animation time, we can add an optional constructor parameter to the
Spinner class.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/640
The startup/busy indication in the app menu was left out of commit
22e21ad7d1 because it doesn't use a hard-coded image, but as the
image in the CSS is actually the same used by the spinner class,
drop the "custom" styling and use the regular spinner.

Object.prototype.hasOwnProperty() is more precise than checking for
falsiness, for instance the following is true:
{ foo: undefined }.hasOwnProperty('foo');
However when checking for a handler ID, a more relaxed check is more
appropriate, as particularly 0 is not a valid handler ID.

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.

We can use that newer method where we don't care about the actual position
of an element inside the array.
(Array.includes() and Array.indexOf() do behave differently in edge cases,
for example in the handling of NaN, but those don't matter to us)

Adds the UI part for the pointer accessibility features.
The various timeouts running are notified using a pie-timer showing
under the pointer.
For dwell-click type selection, we use a drop-down menu. Users can
use the dwell-click to select the next type of dwell click to be
emitted.

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.

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.

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.

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%)
