Currently we consider the last item animating being the last actor of
the list, but that's wrong since the last item animating depends on the
distance between the source actor and the original position of the
animated actor.
Take that into account to check the last item of the animation.
The code that cleaned up when a background actor was destroyed tried to access
the Background as backgroundActor.background._delegate but when the destroy
signal is emitted, the MetaBackgroundActor was already disposed and
backgroundActor.background NULL.
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.

When you open or close a PopupSubMenu the arrow icon rotates, but
the code previously assumed that the starting angle was a multiple
of 90. If you click the submenu fast enough the rotation could overlap
with the previous rotation and you'd get something that wasn't a multiple
of 90.
Now we ensure that the ending arrowRotation angle is always a multiple
of 90 regardless of what the starting angle is.

Commit 12845f0eef reset translationX to 0 to fix the slide-in
animation of the dash when dragging a search result, but 0 is the
wrong value for the thumbnail slider - the next time it will be
shown, it will just pop up instead of sliding in due to translationX
already being at its target value.
Fix this by making _updateTranslation take the actual visibility into
account and call that to set the correct translation in dragBegin.
Controls are slided in by animating translationX from the actor's
width to 0; however as _updateTranslation() will skip the animation
when the property is already at its target value and 0 happens to be
the initial value of translationX, the initial animation is skipped.
Fix this by initializing translationX to undefined, which will always
differ from a valid target value.
The comment is right, updating the translation should be deferred
to pageEmpty, or else overview controls will just pop up instead
of sliding in. So revert that part of commit 6a7fa52879.
Providers that need drag-and-drop behavior can implement this via the
createResultObject() hook (as the app search provider already does), no
need to duplicate that code in the generic result objects
(ListSearchResult already does not implement DND).

This reverts commit a84fb99c0a.
This commit didn't make the OSK fully operational yet on Wayland, and
caused the double emission of key events on X11 due to the OSK keys
receiving first touch events from the passive touch grab, and then
emulated pointer events from event selection after the touch sequence
was rejected in the grab.
When we make a better effort at handling touch events just once on X11,
this commit can be reapplied and remaining wayland OSK support resumed
from there. In the mean time, this patch is better reverted.

All derived classes are already checking explicitly for action names
(FOO and FOO_BACKWARDS). mutter used to have a META_KEY_BINDING_REVERSES
flag for keybindings which required special handling of "shift"+FOO as
FOO_BACKWARDS, but this has been removed now, so this special handling
is no longer necessary.
https://bugzilla.gnome.org/show_bug.cgi?id=732296
When this flag is set on a MetaKeyBinding, mutter will know that
the keybinding has an associated reverse keybinding triggered with
the shift modifier. However, an undesirable side-effect is that
gnome-control-center keyboard panel does not know that this 'shift'
is reserved for these reverse keybindings and cannot detect
conflicting bindings in this case.
This 'reverse' logic can now be handled at a higher level (in gcc keyboard
panel) so this commit removes it from gnome-shell so that they do not
conflict.
https://bugzilla.gnome.org/show_bug.cgi?id=732296

'reversed' or not, gnome-shell does not have to hardcode that a

Having the on/off setting be backed by a boolean in dconf makes sense
anyway but this is mainly to be able to remember the max accuracy set
before user disabled geolocation so that when they enable it next time,
we have the max accuracy level on same value as before.
There hasn't been a real need for this but now we are about to add
geolocation settings in control center and it'll be easiser for
control-center to simply toggle a boolean property rather than to have
to know about and deal with accuracy levels.
Later we might also want to add accuracy level settings to privacy panel
so keeping the accuracy level setting around still. However we no longer
support 'off' accuracy level as the new boolean property covers that.
This also implies that we no longer track available accuracy level,

The zooming animation of the windows looks nice when animating

Currently we are overriding the explicit calls to slideIn
given that it's called also with the signal of showing overview.
It was necessary because of the bug that previous patch fixed,
so now we can just delete that.
https://bugzilla.gnome.org/show_bug.cgi?id=732901
The slide of thumbnailWorkspace is shown when entering overview,
connecting to the same signal that creates the thumbnails, the showing
signal of overview, but, to make the slide animation we need to know how
much width the slider has. To do that we ask the thumbnailsWorkspace
about its width, but given that it connects to the same signal it could
ask the width without having created the thumbnails yet, so reporting a
width of 0 and confusing the slide animation.
Currently it works because gjs calls the callbacks following the order
of the clients connecting that signal, and the thumbnailsWorskpace is
connected before the slide ones.
To avoid that we allow to request the preferred size of the
thumbnailsBox at any time with any number of thumbnails. The only thing
required is to make sure the porthole is accessible when requesting the
preferred size.

We were calling twice showPage() with the correct page, here and in
show() / zoomFromOverview given that _resetShowAppsbutton was called
from the signal 'showing' of overview. Given that the call to
_resetShowAppsbutton is only actually used when hiding the overview we
can actually put the checked state of the button to false when animating
from overview so it shows the workspace page, causing the same behavior
of _resetShowAppsbutton without all the shenanigans of resetting when
the hiding overview signal is triggered.
https://bugzilla.gnome.org/show_bug.cgi?id=732901
Currently the indicators are a BoxLayout inside a BinLayout in AllView.
BinLayout doesn't have any size constraint, so if the indicators request
a bigger size than AllView the entire overview is grown, causing the
overview to go crazy.
To avoid that, create an actor for the page indicators that request as
minimum size 0, and as a natural size, the sum of all indicators natural
sizes. Then we clip_to_allocation, so it doesn't grow more than the
parent.

Both Panel.ActivitiesButton and its parent class Panel.MenuButton would

function twice.

to the signal. Both methods were calling this.menu.close(), so only
do that on the parent class handler, since we're chaining up and doing
the right thing now.

The grab would previously just consume the button release, while propagating
motion events, possibly down to clients in wayland. This would produce
inconsistent streams there.
On pointer events, the inconsistency would just be having clients receiving
events with the button 1 set in the mask, with no implicit grab. When touch
events are handled, this would be more hindering as the client would receive
touch_motion events with no prior touch_down nor later touch_up, something
never supposed to happen.

Currently to know how many results we could show for GridResults
we use the width of the bin containing those results. Since it's
expanding it shouldn't be a problem. But it becomes a problem when
no results are displayed, thus the container becomes hidden and
it losts its allocation.
In the next introduction of terms in search we call again
maxDisplayedResults but it doesn't have allocation yet, and therefore no
results are displayed (currently a bug on IconGrid makes the min size =
one icon, so actually we show one and only one icon in this case).
To solve that use the parent container which contains the search results
of all providers or the text label with not displayed results, so it
always have the real available width to calculate maxDisplayedResults.

We currently replay events that should start a search to the search
entry, which is fairly dodgy. Synthesize a new event with the correct
source actor instead, which is a bit less evil.
If an active grab on pointer events happens during multi-touch operations,
all non-pointer-emulating touches will be muted. This may leave the
Clutter.ClickAction incomplete if triggered by one of those sequences,
just to have a gesture take over and trigger a compositor grab, which would
leave the capture-event handler stuck eating events.
So listen for grab-op-begin from the display, and ensure the action is
released if such grab begins.
and the capture event handler stuck.
When returning to the desktop from overview we always show the
workspaceDisplay, given that is which have the windows clones to allow
animations.
The problem becomes when previous that we were at some other
page, like Search or AppDisplay. The problem is that when showing the
workspaceDisplay the windows are repositioned. That's wanted except
when returning from overview, since that causes unwanted animations
of the windows.
To avoid that just not reposition the windows if leaving the overview.
We don't normally hit the code in scripting.js to print metrics

We must remove the old image from the cache, not the new one.
This was causing a leak of old (and expensive) background
images, and was causing errors at the end of animations, trying
to destroy the animated background.
We translate 'On' to available accuracy level but if available accuracy
level later changes, we don't update available accuracy level accordingly
and hence limit the accuracy of apps.
E.g if available accuracy level is 'city' and geolocation is enabled,
the max accuracy level would be 'city' and apps can't get higher than
that. Now if user plugs in GPS, the available accuracy level will change
to 'exact' but without this patch max accuracy level will remain to be
'city' and apps will not be able to use the GPS.

Commit 5d00c1a5ee moved app folder popups to GrabHelper - for some
reason, the line that ensures the current behavior of only considering
events inside the app picker to dismiss popups got lost ...
As clicks outside the app picker should still be handled normally
while clicks inside should dismiss the popup, we cannot make full
use of GrabHelper. However using it at least for focus handling
fixes some minor details we are getting wrong, for instance not
restoring the previous focus after dismissing a folder popup.
Commit 6c2f3d1d17 moved pref overrides into JS to implement
session mode specific overrides in a clean and generic way.
However that approach comes with a cost - doing the overrides only
after having handled over control to JS means that the core will
be initialized with the non-overridden settings before changing
to the correct values. In the best case this is unnecessary work,
but it can in fact have a worse effect: when initializing workspaces,
we will restore the previous number of workspaces when using
dynamic-workspaces and reset to the configured number otherwise.
As the non-overridden default for dynamic-workspaces is FALSE, we
can easily end up moving the user's windows to the "wrong" workspace.
Now GSettings is expected to grow support for session specific defaults,
which will render our entire override system obsolete (yay!). Given
that, it seems acceptable to use a less generic (and uglier) approach
in the meanwhile, in order to fix aforementioned problems. So move
overrides back before core initialization and just hardcode the
session-mode => override-schema relation.

The 0x0 dummyCursor works well when the menu pops up directly underneath
the pointer (e.g. when triggered by right-clicking the titlebar) or by
keyboard, but not when triggered by the menu button - the menu does not
point to the center of the button's bottom edge, and unless the user
keeps holding the mouse button while moving into the menu, the menu will
be dismissed immediately on button release.
Address these issues by using the button geometry to overlay the window
button with an appropriately sized actor that acts as a proper sourceActor,
to make the window menu behavior consistent with other shell menus.

When the pointer leaves the notification area, we queue a timeout to
hide the notification after a little while. If the user is hovering over
a notification and clicks the X button to close the notification, we will
destroy the notification, which causes a "pointer left" event on the
notification area. This queues a timeout which erroneously fires after
the next notification in the queue shows up.
The code and state machine are too complex to properly make sure this
timeout doesn't fire when there is no notification up next, so instead
just clear it when showing a notification to make sure that any
previously queued timeout doesn't apply to us.

Starting keynav into the active page is handled from a key-press
handler on the stage, however we should not "start" keynav when

up to the stage. So make sure to only handle the event to actually
