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.

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.

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.

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.

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.

The AnimatedIcon does not have an API for controlling the animation but

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

Switch to a start/stop API instead. Also, update to the first frame at
startup while we are at it, since this is the expected behavior.

While we recreate icons on style changes elsewhere, the faded
icon in the application menu will stick around after icon theme
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.

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.

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.
