The rewrite of Mutter's background code (see bug 735637) requires
corresponding changes here - we no longer need to layer multiple
MetaBackgroundActors together.
The general strategy is that a BackgroundSource object is created
per GSettings schema, and keeps either one Background/MetaBackground pair,
or, for animation, a Background/Metabackground pair for each monitor.

Support was added to Mutter to allow it to trigger a restart
to allow for restarts when switching in or out of stereo mode.
Hook up to the new signals on MetaDisplay to show the restart
message and reexec. Meta.is_restart() is used to suppress
the startup animation.
This also allows us to do 'Alt-F2 r' restarts more cleanly
without a visual flash and animation.

NetWM struts are defined in terms of screen edges (rather than monitor
edges), which works poorly with vertical monitor layouts (as it renders
entire monitors unusable). Don't extend struts in those cases.

This code may have worked when written in 2009, but later gjs commit
b5e467d89aea43a8e32a1138d232c8a32e6b0785 removed the priority
parameter from idle_add.
Now, when running a constantly-updating client (es2gears) on an
embedded platform, _updateRegions() does not get called and I see
unresponsive window decorations.
Update the code to use meta_later_add() like other parts of the
shell, which is actually slightly better in this case anyway.
Solves the unresponsiveness problem.

If an actor is destroyed, calling get_transformed_size()/position()
can return bogus values and trigger JS exceptions.
This can happen if a tracked actor comes from an extension
(such as classic mode's window-list) and that extension is
deactivated.

Right now we have three "dummy cursor" widgets between the background
menu, the message tray menu, and the IBus candidate popup. Consolidate
these into one "dummy cursor" widget which is tracked in the layout
manager.
If monitor-changed fires at startup, it will destroy all of the
backgrounds, but since this._isStartup is true, won't recreate any
of them. Additionally, since _bgManagers is indexed by monitor index,
if the primary index is not 0, it could become a sparse array (e.g.
[undefined, undefined, primaryBackground]), and our for loop will
crash trying to access properties of undefined.
Fix both of these issues by always creating background managers for
every monitor, hiding them on startup but only showing them after
the startup animation is complete.
One thing we need to watch out for is that while LayoutManager is
constructing, Main.uiGroup / Main.layoutManager will be undefined,
so addBackgroundMenu will fail. Fix this by passing down the uiGroup
to the background menu code.

We cannot wait for the queued update region to fire when
xdnd is being used because a wrong input shape can result
into a xdnd leave event when the user moves the pointer fast.
https://bugzilla.gnome.org/show_bug.cgi?id=708887
Don't assume that this._bgManagers.push() (i.e adding to the end) is always
correct.
On startup we call _createPrimaryBackground which passes in the primary index
which may not be 0.
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 top_window_group was introduced for popup windows that should
appear above system chrome, but as the group itself is just a child
of Main.uiGroup, chrome that is added after top_window_group will
still be stacked on top.
At least correct the stacking for actors added via addChrome().
https://bugzilla.gnome.org/show_bug.cgi?id=702338
In order to make sure that the struts and regions are initialized,
we need to make sure that we do with the conditions that nothing
is transformed, like the uiGroup, and that everything is visible.
These invariants broke during a fix to hide the UI until the
system background texture could be loaded. Now, reorder things so
that the system background is loaded, and then the UI is properly
loaded, and so on.
https://bugzilla.gnome.org/show_bug.cgi?id=696159
Instead of using the input mode, when the overview is not modal
it should use a Chrome-tracked actor, that is added to the input
region. Because the overview always takes pointer input when
visible, the actor is added at startup, and it is shown and hidden
as needed.

Since we now have global.screen::in-fullscreen-changed, remove the
duplicate signal. To prevent ordering problems in connecting to
this signal, make inFullscreen a property-function of a new Monitor
object rather than a data property we tack on to a Rectangle object.
https://bugzilla.gnome.org/show_bug.cgi?id=649748
This ensures that when we have windows that are already visible,
like desktop icons, they don't fly across the screen from what
seems to be hyperspace to get into view.
https://bugzilla.gnome.org/show_bug.cgi?id=696323
In the (no barriers) fallback case handleDragOver has somehow
ended up being turned into a nop and thus breaking xdnd
overview opening.
Fix that by calling _toggleOverview() when a xdnd source triggers
it.

Getting fullscreen window tracking right in GNOME Shell turned out to
be very hard, because it depended on details both how Mutter handled
fullscreen windows and the exact timing of that. Fullscreen tracking
and auto-minimization of fullscreen windows that lose their fullscreen
status has thus been implemented in Mutter: use that.
https://bugzilla.gnome.org/show_bug.cgi?id=649748
It's possible in some corner cases for the status of the topwindow
to change and make it not fullscreen without ::restacked being
changed. One way that it could happen with the old code was if the
layer of the top window changed from NORMAL to FULLSCREEN.
Change the logic not to look at the layer, which is a function of
Mutter's *intended* stacking, rather than the *actual* stacking,
which is what ::restacked gives you. Instead, look at the top
portion of the stack, down to the first non-override-redirect
window, and see if their are any monitor-sized windows there.
Connect to changes on the top portion of the stack, so we know
if conditions change.
https://bugzilla.gnome.org/show_bug.cgi?id=649748
It makes more sense to use the monitor the tray is on, rather than the
primary monitor. This also matches us with whether we can open the tray
from a barrier/dwell or not.
