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.

Previously when a client requests that a window should be docked the
shell would reparent the socket window onto the stage's window and
then use ClutterX11TexturePixmap to get a texture to represent the
window. This will not work if Clutter is no longer using the X11
winsys for example if it becomes its own display server. Instead this
patch leaves the socket window as a child of the root window and lets
mutter create a MetaWindow out of it. If Mutter is acting as a display
server then this mechanism will still work via the headless x server.
The ShellGtkEmbed instance now registers for notification of the
‘window-created’ signal of the display so that it can find the
MetaWindow that gets created to represent the socket window. When this
window is found it is prevented from being displayed on the screen by
setting the actor's opacity to 0. An input shape is then set on the
window to prevent it receiving any input.
Instead of being a subclass of ClutterX11TexturePixmap, ShellGtkEmbed
is now a subclass of ClutterClone. When the MetaWindow is found for
the socket window the clone's source is set to the invisible actor for
the window so it can be displayed in the panel as before.
The ShellEmbeddedWindow no longer needs to know what the stage is
because it no longer reparents the socket window. Therefore the
ShellTrayManager doesn't need to know the stage either so
shell_tray_manager_manage_stage has been replaced with just
shell_tray_manager_manage_screen.

To create a new workspace by dropping on the placeholder, we move all
the windows down one workspace and then wait for _checkWorkspaces() to
automatically create the empty one at the end.
This means that, from the implementation POV, the new workspace is not
the one created by DND but it's the last one, and this detail was exposed
in the UI because the animation was applied on that one.
Fix that by starting the animation manually from the DND code, and then
blocking the animation from happening when the new workspace is created
with a flag.
https://bugzilla.gnome.org/show_bug.cgi?id=685285
DND of windows has a lot of side effects, including the possibility of
current workspace disappering from under our feet. We need to account
for that when trying to activate it.
https://bugzilla.gnome.org/show_bug.cgi?id=685285
This happens in the case of Workspace/WorkspaceThumbnail: they call
meta_window_change_workspace_by_index(), which fires window-removed
on the old workspace, thus destroying the window clone.
https://bugzilla.gnome.org/show_bug.cgi?id=685285
Windows can be restacked at any time, including when the stackAbove
property of the window clone is being dragged, and thus parented to
the uiGroup. To do stacking properly, we need to skip it for the duration
of the drag, and sync it again at the end (which is already done by
mutter because of the workspace change)

ClutterBinLayout uses the maximum width/height of all children in
size requests and positions children according to the expand/align
properties. This means that the vertical position of folder popups
is not considered in size requests, so if the main view is smaller
than a folder popup's height and offset, the popup will be truncated
and/or mispositioned. Fix those cases by using a custom LayoutManager
that behaves like ClutterFixedLayout for height requests and like
ClutterBinLayout otherwise.

The login dialog has a maximum height set to prevent the user list
from growing indefinitively. However this approach fails if the
monitor height is smaller as said maximum, so add some additional
top/bottom padding to make sure there's some whitespace above/below
the user list in that case as well.

Commit 7b3a689aad changed the border-radius of the hover effect
to match the prelight effect, but not the focus indication, so
the focused item now changes corners on hover. Fix this by using
a consistent border-radius.

We need to look at the duration of the current step of the slideshow
to determine when to next queue an event, rather than the full slideshow
duration.

Due to weird and strange JS scoping semantics, if we are in a
callback, "i" won't be captured and when the callback is called,
we'll have the wrong index, causing addImage to be called instead
of updateImage.
https://bugzilla.gnome.org/show_bug.cgi?id=695882
The pattern is underneath, so we need to add one. It turns out
that ClutterGroup doesn't care about that, but we need to do this
to remove deprecations in mutter.

To make sure that the screen shield is shown before suspending, we
take a logind inhibitor and release it when the screen shield is
shown. As the screen shield is not only shown on suspend, we can end
up releasing the inhibitor independently from suspending (lock, idle),
in which case the screen might not be locked when we do suspend.
To fix, only release the inhibitor after showing the screen shield
when we are about to suspend.

Since commit 7cdb75e7ce, initializing UI is deferred until the session
mode has been loaded. However DBus is still initialized immediately,
which means that for DBus methods that access properties in Main, there
is now a window between the method being exposed on the bus and the
method being ready to be called. At least g-s-d grabbing global keybindings
is likely to fall in this window on session startup, and almost guaranteed
when regrabbing bindings after a shell restart.
To fix, defer initializing DBus as well.

When we switch into an invalid input source we hide the panel
indicator and return early but we were not hiding the previously
active source label and its menu item dot and thus when switching
again to a third input source we would end up showing 2 overlapping
labels in the panel and the menu would have 2 entries with a dot.

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.

We always add external DOCK windows to the ctrl-alt-tab switcher,
e.g. separate dock applications or nautilus' desktop windows.
Since commit 1f46a0dc26, all items in the switcher are expected
to set a proxy parameter, but the aforementioned code was not
updated accordingly.

* Prompters have state, and cancelling an already prompter will
cause prompts that are in progress to fail.
* In addition allow replacement of our shell prompter for debugging
purposes.

notify::* doesn't guarantee that the value has changed, only that it
may have been. We need to ensure that we track the old value to make sure
we don't do things like overwrite timeouts if they already exist.
