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.
https://bugzilla.gnome.org/show_bug.cgi?id=700735
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.
https://bugzilla.gnome.org/show_bug.cgi?id=700735
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.
https://bugzilla.gnome.org/show_bug.cgi?id=695659
For the same reasons that we disable the tray barrier, we should
disable hot corners as well -- when users have a full-screen game
open, we shouldn't allow overview activation by the hotcorner.
https://bugzilla.gnome.org/show_bug.cgi?id=694997
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
For the HotCorner, we want to have different logic for tossing out
specific events based on the grabbed state, etc. so make us have
to pass in an event filter callback.
For the hot corner case, we want to have the pressure apply both in
and outside of the overview, so we need to move this to the user. At
the same time, use keybinding mode math that's more like what's used
in filterKeybinding.
While it may seem like an abuse of the KeyBindingMode API, it may
become more reasonable if one thinks of the pressure barrier as a
binding of sorts, just applied to the mouse. If a ButtonBinding API
was added to mutter, I think we'd use the existing KeyBindingMode
infastructure there as well.
Ensure that the pointer leaves the barrier before we trigger again.
For the message tray case, this doesn't matter much, as the trigger
won't have any effect after the grab is taken, but in the overview
HotCorner case, this ensures that we don't trigger the overview
transition many times simply by holding pressure against the hot
corner, which is easy to do accidentally.
Toggling the overview during the startup animation reportedly
causes stuck grab and other odd behavior.
There's no reason to handle toggling the overview during this
time anyway.
This commit defers that handling until after startup.
