The existing app menu was a kludge of legacy code that tried to manage
a bunch of state, and had a number of issues:
* It didn't properly manage visibility when combined with multiple
apps and the overview.
* It didn't properly manage reactivity when tabbing away from a busy
app to another app.
* It didn't properly disconnect signals when going from one app
to nothing.
and countless others. Rewrite it to use the new "sync" code pattern,
where we centralize all state management and do transitions from that,
rather than strange and quirky control flow.

To align the arrows, we need to allocate panel buttons the full
height of the tray. Fix up all of the panel buttons to support this,
and align the arrows in the middle.

Swap out the implementation of SystemIndicator with a dummy,
and build the aggregate menu. At the same time, remove the
poweroff and login screen menus, as those were fake aggregate
menus beforehand.
We lose some flexibility as we lose session-mode-based menu
layout, but as each component of the aggregate menu is supposed
to be "smart" in response to updating itself when session
state changes, I believe it's better than a declarative model.

The point of fading the icon is to make the text displayed over the
icon more legible. In RTL layouts, the text is displayed on the left
of the icon, so fading the right-hand-side of the icon doesn't work
well.

The duality of the Clutter's key focus and mutter's window focus has long been
a problem for us in lots of case, and caused us to create large and complicated
hacks to get around the issue, including GrabHelper's focus grab model.
Instead of doing this, tie basic focus management into the core of gnome-shell,
instead of requiring complex "application-level" management to get it done
right.
Do this by making sure that only one of an actor or window can be focused at
the same time, and apply the appropriate logic to drop one or the other,
reactively.
Modals are considered a special case, as we grab all keyboard events, but at
the X level, the client window still has focus. Make sure to not do any input
synchronization when we have a modal.
At the same time, remove the FOCUSED input mode, as it's no longer necessary.

The class is generally useful, so it only makes sense in panel.js
for historical reasons. Because other parts of the code are
using it, though, problems are cropping up that require a
workaround like:
placeSpinner: function(...) {
/* This is here because of recursive imports */
const Panel = imports.ui.panel;
Panel.AnimatedIcon(spinnerIcon, WORK_SPINNER_ICON_SIZE);
...
}
This commit moves AnimatedIcon to its own file so we can drop that
workaround.

It makes sense to allow closing the app menu with the same shortcut
that is used to open it, so make it a toggle action and allow it
TOPBAR_POPUP mode.

If for some reason an extension needs to destroy the AppMenu object,
currently it is not possible to do this cleanly due to these signals
remaining connected.

In order to use a different spinner image in classic mode (or any
other mode specific style), get it from CSS rather than hardcoding
a particular image.
https://bugzilla.gnome.org/show_bug.cgi?id=693688
For classic mode, we want to use a different styling for the spinner,
so we will pick up the image filename from CSS to make use of mode
specific styling. As the CSS will give us a full pathname, adapt the
API to take a full pathname instead of building it inside AnimatedIcon
from the passed basename.

Rather than expose a dizzying array of methods related to managing
state that require infecting every user of the overview methods, try
to do the sensible and smart thing internally. Now, the overview
itself tracks when XDND drags start, and simply calling show, hide or
toggle while an XDnD drag is in effect will show the overview, and
will only take the grab until after the XDND drag ends.
https://bugzilla.gnome.org/show_bug.cgi?id=663661
This cleans up the code considerably, and makes it so that
one path creates all hot corners for all monitors. Why this
wasn't done originally, I have no clue...
The one complication is debouncing if the button and hot corner
are triggered in rapid succession, so we just move this tracking
to the overview.
https://bugzilla.gnome.org/show_bug.cgi?id=663661
The panel used to provide an .in-overview class which was removed after
the theme stopped using it. Classic mode should use a different top bar
style in the overview, so bring it back (but use a pseudo class this
time for consistency with MessageTray and ActivitiesButton).

In time span between idle and lock the shield should behave like autologin,

Due to limitations and bugs in SpiderMonkey's GC, wrapper objects
for cairo contexts and similar may not get cleaned up immediately
after repainting, leading to leaking memory. Explicitly disposing
of such objects after they're not needed can clean up large portions
of memory for cairo surfaces.

With panel buttons changing dynamically on session mode changes we can
no longer rely on a corner's respective box style-changed signal to
find the nearest button.
Instead, make the panel take care of telling the corners to look for a
new button when buttons are changed.
https://bugzilla.gnome.org/show_bug.cgi?id=690180
Use the new meta_window_check_alive() to verify if the application is
responding after the user activates an action from the app menu.
This in particular restores the ability to force quit applications
from the menu, even if the use a custom GMenu.
https://bugzilla.gnome.org/show_bug.cgi?id=684340
The panel should change appearance according to the sessionMode,
so add a new panelStyle sessionMode property which allows to
specify a mode specific style class for the panel actors.
https://bugzilla.gnome.org/show_bug.cgi?id=684573
The panel corners overlap the panel in order to hide the underline
used for active buttons where it is supposed to arc downwards
following the roundness of the corner.
Unfortunately this prevents us from using a transparent panel background,
as the overlapped area ends up with the wrong transparency. Work around
this limitation by only overlapping the panel if there is a visible
border.
https://bugzilla.gnome.org/show_bug.cgi?id=684573
The top panel and message tray icons were by default a gnome foot and
are replaced by better ones. The applications icon is now using the
symbolic apps icon of the dash, and the windows icon is also improved.

The AnimatedIcon does not have an API for controlling the animation but
relies on the :visible property changes to start and stop a timeout used
to update the frame.
This has the inconvenient of having a side effect when visible is set to
true multiple times, and is not really the API expected from such
component. Also, there is a race if it is displayed before the images
are loaded: there is no child yet and thus we get this._frame = NaN
which leads to a crash.
Switch to a play/stop API instead, and add a load event callback to the
TextureCache.load_slice_image to exactly know when we can start using
the images.

While we recreate icons on style changes elsewhere, the faded

changes until another application is focused.

GDM has a 'logo' key in its schema to allow distributors to add
some branding. It is currently placed above the user list, which
no longer works too well since the login screen lost its dialog
window. Display the logo in the top-left corner instead of the
Activities button instead.
https://bugzilla.gnome.org/show_bug.cgi?id=685852
Since panel corners are currently square, this doesn't really affect much,
but it's very clear what the code was supposed to be. At the same time,
also fix up a redeclaration with 'let', which technically isnt' kosher.
Panel already forces each item to be a PanelMenu.Button, so it's better
to have the latter handle the bin container too, instead of attaching
a private property that might collide with internal usage by the indicator.
https://bugzilla.gnome.org/show_bug.cgi?id=683156
If we don't freeze the presence icon, we can end up in a place where
we'll be updating the icon before we fade out the panel indicators when
coming back from the lock screen.
https://bugzilla.gnome.org/show_bug.cgi?id=683156
Since we eventually want to add a system for changing the top panel
contents depending on the current state of the shell, let's use the
"session mode" feature for this, and add a mechanism for updating the
session mode at runtime. Add support for every key besides the two
functional keys, and make all the components update automatically when the
session mode is changed. Add a new lock-screen mode, and make the lock
screen change to this when locked.
https://bugzilla.gnome.org/show_bug.cgi?id=683156
We already could build the right part of the panel declaratively according
to the session mode. Extend that to handle the left and center parts.
Also, move the mapping from the roles to the classes in panel.js, as it shared
by all modes.
https://bugzilla.gnome.org/show_bug.cgi?id=682546
The design has a combined volume-network-power indicator in the lock
screen, which when opened shows a volume slider. Implement it by abstracting
the volume menu into a PopupMenuSection, and by creating three StIcons
bound to the real ones.
https://bugzilla.gnome.org/show_bug.cgi?id=682540
The app menu is hidden when entering the lock screen, however it
might be shown again while the lock is still in place - we don't
want this ever to be the case, so make show() a no-op while the
screen is locked.
https://bugzilla.gnome.org/show_bug.cgi?id=682475
Track locked status and use it to provide a reduced version of
the panel in the locked screen. Accessibility, input sources and
volume menus are preserved, without the link to the control center.
Network, battery and user menu are reduced to pure indicators,
with no menu.
This is similar to the design but not exactly, because designers
in IRC said that network needs more analysis before exposing, and
because the design didn't account for a11y and IM (so the one menu
metaphor is not really appropriate).
https://bugzilla.gnome.org/show_bug.cgi?id=619955
Previous code would access the array element before checking that
the index was within bounds, and therefore cause a TypeError.
It wasn't noticed earlier because at least one visible children
is in each panel box in all session modes.
https://bugzilla.gnome.org/show_bug.cgi?id=619955
When activating the app menu while displaying a startup notification
animation, the application shown in the menu does not match the
application providing the menu. To avoid this case, make the menu
button unreactive while playing the animation.
https://bugzilla.gnome.org/show_bug.cgi?id=672322
Rather than accessing global.session_type / global.session_mode
all over the place, delegate mode information to a dedicated
sessionMode object. While not very useful for now, we will replace
checks for a particular mode with checks for particular properties
that sessionMode defines based on global.session_mode.
https://bugzilla.gnome.org/show_bug.cgi?id=676156
When the appMenu is not available, for instance when no windows are
open (on the current workspace), we make its actor unreactive to
"hide" it from keynav. However the menu can still be triggered
erroneously when using the corresponding keyboard shortcut, so
add a check for the actor's reactivity there as well.
https://bugzilla.gnome.org/show_bug.cgi?id=676316
With the application menu now being more than a stub, it has
become a much more interesting target, so add a keyboard shortcut
to open it directly.
This should also ease some of the pain for focus-follows-mouse users.
https://bugzilla.gnome.org/show_bug.cgi?id=672909
Bailing out of _sync() early if the application lost keyboard focus to
the shell can only be done on actual application focus changes. In
particular, doing this check on a switch to an empty workspace while
the keyboard focus is already on the shell prevents the AppMenuButton
from being hidden as it should.
https://bugzilla.gnome.org/show_bug.cgi?id=672011
Reactive means that the actor is reachable from keyboard
navigation. If the target isn't current that means we are not tweening
the actor to be visible so we shouldn't set it reactive either.
https://bugzilla.gnome.org/show_bug.cgi?id=671998
The preferred way to unmaximize/untile a window is by using a drag
gesture. Extend the available area to start this gesture into
non-reactive parts of the top bar above the window - with that we
take advantage of the "infinite height" of the screen edge, and the
extra space is particularly useful when the window has its titlebar
hidden.
https://bugzilla.gnome.org/show_bug.cgi?id=666359
Currently they return 'undefined' instead of something meaningful,
e.g. DND.DragMotionResult.CONTINUE. This was unnoticed because none
of the ancestors of the Activities button actors do any drag handling.
The only visible issue are JS errors generated when dragging, for example,
a window thumbnail over the button, because the cursor cannot be set.
https://bugzilla.gnome.org/show_bug.cgi?id=669921
When the last window on a workspace is closed the focus goes to some other
window in another workspace which would cause us to show the AppMenuButton for
an application that isn't visible on the current empty workspace.
https://bugzilla.gnome.org/show_bug.cgi?id=643867
Since the application proxy is created asynchronously, at the time
the GActionGroup (GActionMuxer) is created, there is no GDBusMenu yet.
Defer creating the menu in that case.
Also, clear out signal handlers if have no target application.
https://bugzilla.gnome.org/show_bug.cgi?id=633028
GTK+ also exports window-specific actions, by putting the object path
for the exported action group in the _DBUS_OBJECT_PATH X property.
We add this action group to the app's muxer with a 'win' prefix,
since that is what the exported menu expects. Whenever the focus
window changes, we update the window-specific actions of its
application, and emit notify::action-group to cause the app
menu to be updated.
By the time the window is first mapped and the app menu button is
synced, we may not have finished reading the menu. In that case,
connect to notify::menu and update accordingly.
Use the new GApplication support in ShellApp to create the application
menu. Supports plain (no state), boolean and double actions.
Includes a test application (as no other application uses GApplication
for actions)
