ES6 finally adds standard class syntax to the language, so we can
replace our custom Lang.Class framework with the new syntax. Any
classes that inherit from GObject will need special treatment,
so limit the port to regular javascript classes for now.

Shell.GenericContainer exposes the size negotiation machinery
through the use of signals. Signals are not specially performant.
One of the reasons is that they acquire a global lock for signal
handlers lookup. GNOME Shell has more than 2,000 actors at any
given point in time, up to 20 levels deep in hierarchy, making
size negotiation and painting non-trivial tasks. Such a critical
section of Clutter's machinery shouldn't rely on signals
whatsoever.
Regardless of that, Shell.GenericContainer is a workaround to
a non-existing issue anymore. It shouldn't be used anyway, and
any performance improvements that removing it can potentially
yield are bonuses to it.
This commit starts this work by removing Shell.GenericContainer
usage from Panel.Panel class. The class now extends St.Widget,
and as such, it has no "this.actor" field set anymore. A couple
of places where this actor field was used are adjuste as well.
It is important to notice that we now allocate the Panel itself
inside vfunc_allocate(). This was previously done before emitting
the signal by Shell.GenericContainer.

We show a cover pane on top of the overview during transitions to
prevent issues caused by clicks and mouseover events when the overview
is not ready. Right now, this pane is only being shown on the primary
monitor, which obviosly allows interactions to happen before the
animations are finished on the secondary monitors.
To fix this, use the size of the whole stage for the cover pane.
Remove any usage of MetaScreen, as it has been removed from libmutter
in the API version 3. The corresponding functionality has been moved
into three different places: MetaDisplay, MetaX11Display (for X11
specific functionality) and MetaWorkspaceManager.
https://bugzilla.gnome.org/show_bug.cgi?id=759538
We don't toggle the overview if the request happens too close to the
last activation, to filter out double-clicks or activation by both
the hot corner and a click. However as the check is based on the
real time, the check breaks if the system clock moves backwards and
the last activations appears to be in the future. Fix this by using
monotonic time which is guaranteed to only move forward.
https://bugzilla.gnome.org/show_bug.cgi?id=763886
When not using arrow notation with anonymous functions, we use Lang.bind()
to bind `this` to named callbacks. However since ES5, this functionality
is already provided by Function.prototype.bind() - in fact, Lang.bind()
itself uses it when no extra arguments are specified. Just use the built-in
function directly where possible, and use arrow notation in the few places
where we pass additional arguments.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/23
These end up emitting item-drag-end/window-drag-end pretty much
without checks. Given the MetaDnd object may end up emitting
::drag-leave as a result of the plugin ending its grab, this
would result on spurious emission of those events and subsequent
warnings.
For extra paranoia, the _inDrag variable has been split into
_inItemDrag/_inWindowDrag so we can't cross the streams.
https://bugzilla.gnome.org/show_bug.cgi?id=784545
Don't assume there will always be a primary (logical) monitor, or any
(logical) monitor at all. This includes not allocating / layouting /
styling correctly when being headless.
The initial background loading will also be delayed until there are any
(logical) monitors connected.

Any symbols (including class properties) that should be visible
outside the module it's defined in need to be defined as global.
For now gjs still allows the access for 'const', but get rid of
the warnings spill now by changing it.

Using a MetaWindowActor's shaped texture as the source for window
clones means that if there are further MetaSurfaceActor children
(e.g. a wayland client using sub-surfaces) they don't get cloned.
This obviously wasn't an issue until wayland clients introduced the
possibility of having multiple MetaSurfaceActors under a
MetaWindowActor but there's no fundamental reason we can't clone the
toplevel actor.
WorkspaceThumbnail.WindowClone is the one class that was already using
the MetaWindowActor instead of the texture although it seems to have
been an unintended change in commit
8b99617513.

Commit c39ffa111 moved the signal handling from the controls- to the
background-group to enable scrolling on non-primary monitors.
However this broke scrolling on reactive overview elements as the
workspace switcher, as they're not descendants of the background.
To fix, move scroll-event handling to the overview group itself,
which is the common ancestor of all overview elements.
https://bugzilla.gnome.org/show_bug.cgi?id=768316
Both the Overview::scroll-event and actions added via addAction()
are meant to work anywhere in the overview, but for now only work
on the primary monitor. Move the handling to the background group
that is known to span all outputs to fix.
https://bugzilla.gnome.org/show_bug.cgi?id=766883
The stack was used to overlay a message indicator over the overview
group. That indicator is long gone, so there's no longer a need for
an intermediate actor in the hierarchy.
https://bugzilla.gnome.org/show_bug.cgi?id=766883
The message tray is now empty and about to be removed, so an indication
at the bottom edge of the overview becomes an odd location to convey the
status of the summary. We will eventually display an indication in the
top bar that unseen messages are available, for now just remove the
existing indicator.
https://bugzilla.gnome.org/show_bug.cgi?id=744850
_hideDone checks _shown to determine if anything has shown the overview
while we hid it, and if so, shows the overview forward just in case.
In a local patch that called _hideDone immediately inside _hide for
testing, this broke. While we don't actually depend on this anywhere,
it doesn't hurt so that the next person to hack this up (perhaps me!)
doesn't get stuck debugging it for 20 minutes.
It is quite weird to have those calls/signals using WindowClone as an
argument, it is neater to pass MetaWindows around, and have each user
deal with their own representations of these.
https://bugzilla.gnome.org/show_bug.cgi?id=735972
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.
https://bugzilla.gnome.org/show_bug.cgi?id=735638
Following design decision, we want to animate AllView and FrequentView
when opening and closing with a swarm spring form.
This involves a few changes needed to allow that, since from some time
now, we are animating page changes in viewSelector, using only a fade
transition. However now we want to let appDisplay and iconGrid apply its
own animation.
For that we special case the change to and from apps page on
viewSelector to let appDisplay to animate its own items, using and API
on appDisplay which at the same time uses an API on iconGrid.
Thanks Florian Müllner for the debugging work

The zooming animation of the windows looks nice when animating
from the workspace display page, but looks weird from other pages
like apps page or search page since the windows come from nowhere
with an initial position not known to the user.
Instead of that just fade the desktop with the windows in its
original position.
https://bugzilla.gnome.org/show_bug.cgi?id=732901
The DESKTOP window might not be located at (0,0), in particular
on multi-monitor setups. While we already consider this by setting
the clone's position, we then stuff the clone into a container which
ignores it - meh ...
https://bugzilla.gnome.org/show_bug.cgi?id=723306
If desktop icons are enabled and not covered by maximized windows,
we will fade them in/out during overview transitions. However when
moving background handling into mutter/gnome-shell, we ended up with
the overview background on top of the DESKTOP window clone, hiding
the fade transition.
Fix the stack order to bring the effect back.

Some consumers may want to construct their buttons specially, so allow them
to do that by adding a new API that takes a button instead of a label.

The cover pane is used to block events during transitions, but as
workspaces don't share the same container as other overview elements,
they are currently excempt from the event blocking.
Move the cover pane to the top-level overview container instead.
https://bugzilla.gnome.org/show_bug.cgi?id=709034
Moving the mouse fast enough during xdnd will trigger a xdnd-leave event
because the input shape is not updated until after the animation is done.
So simply ignore the leave events while the animation is in progress.
https://bugzilla.gnome.org/show_bug.cgi?id=708887
This method, which accepts a .desktop filename, is used to highlight
a specific application in the overview, for example because it has
just been created or installed.
https://bugzilla.gnome.org/show_bug.cgi?id=654086
The event catcher that covers the entire primary monitor during
transitions is currently inside a BoxLayout, relying in its
odd support for fixed position actors.
We already have a proper stack widget in place, move it there.
https://bugzilla.gnome.org/show_bug.cgi?id=703808
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
Some keyboard spot a dedicated search key, which gnome-settings-daemon
currently handles by spawning gnome-search-tool. It makes a lot of
sense to promote the Shell's integrated search feature instead, so
expose an appropriate DBus method g-s-d can use.
https://bugzilla.gnome.org/show_bug.cgi?id=700536
Instead of creating a bunch of random actors and then passing
them off to the controls manager, let the controls manager
construct them. This leaves the controls manager in charge
of the ordeal.
https://bugzilla.gnome.org/show_bug.cgi?id=694469
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
Previously, the overview BoxLayout was sized and positioned explicitly
using the primary monitor coordinates, as its parent was at 0,0 and
with a fixed layout manager. Now we use a bin layout, so we need to
position and size the stack actor, and set the overview boxlayout to
expand.
Take also the occasion to use a MonitorConstraint instead of handling
position and size manually.
https://bugzilla.gnome.org/show_bug.cgi?id=694969
We used to clip the overview group to prevent the dash from sliding into
neighbor monitors, but now it moved to the groupStack, so we must move
the clip too.
https://bugzilla.gnome.org/show_bug.cgi?id=694970
We generally want view content centered, in particular where the
view itself is symmetrical. So move the dash to a separate layer
and use a placeholder to account for its size when showing the
window picker, which is the only view where it doesn't make sense
to center the content.
https://bugzilla.gnome.org/show_bug.cgi?id=694261
Commit 43ed66cf26 changed the toplevel overview actor, so it
makes sense to change the show/hide transitions to use that instead
of the existing group, to avoid elements layered on top of the
group being excluded from the transitions.
It is useful at times to perform several actions that would usually
close the overview (for instance launching an application) at once.
Currently we allow this by dragging items to a workspace rather than
just clicking it, but it's an odd metaphor with its own set of
problems.
Introduce an alternative approach (inspired by file selection in
file managers) by keeping the overview open if a Control key is
held down.
https://bugzilla.gnome.org/show_bug.cgi?id=686984
Using the scroll wheel in the window picker should switch workspaces.
As the picker doesn't have a visible boundary though, it makes sense
to accept scroll-event for the entire overview area. Rather than
making the overview's main actor public, expose scroll-events via
a signal.

This commit updates the code to use mutter's new background
api, and changes the shell's startup animation to be closer

All the complexity with a custom actor and a generic container was
just to add some padding below the overview controls. Remove that,
and use CSS instead.
https://bugzilla.gnome.org/show_bug.cgi?id=694100
Account for the search entry space at the bottom (the former message
tray clone) individually in each side control, instead of packing
another actor in the overview.
This allows us to extend the central view all the way to the bottom,
while still keeping controls centered vertically.
https://bugzilla.gnome.org/show_bug.cgi?id=693987
And use it in overviewControls. When we moved this code from overview.js
to overviewControls.js we lost a condition so we now slide in controls
even when going back from the overview, which looks bad.
https://bugzilla.gnome.org/show_bug.cgi?id=693974
Both WorkspacesDisplay and ThumbnailsBox need to know when windows have been
restacked. Instead of each tracking changes on their own or trying to call
each other, have the overview keep track and do the calculations, emitting
a signal with the result.
https://bugzilla.gnome.org/show_bug.cgi?id=690175
Adjust the layout of the overview and window thumbnails to make them
bigger. Also, make the background shade darker to compensate for the
increased thumbnail density.
https://bugzilla.gnome.org/show_bug.cgi?id=689876
The message tray actor also includes notifications themselves. We want
our ghost to be sized as the base part of the tray instead.
Just make sure to use the same style class as the base actor then, as
its height is specified by the CSS.
https://bugzilla.gnome.org/show_bug.cgi?id=690174
When pressing the overlay key three times, things went like this:
* show(), push a modal
* hide(), will pop a modal after hiding is done
* show(), push a modal
Thus, when the showing is done, and then it activated the hiding,
it popped one modal, but not the other. This patch changes things
to be:
* show(), push a modal
* hide(), will pop a modal after hiding is done
* hide(), no-op
That is, mashing the overlay-key when it's showing will always make
it hide, not mashing an odd number of times.
https://bugzilla.gnome.org/show_bug.cgi?id=688589
Currently we assume that either the initial sessionMode will have
the overview or none of the pushed modes - starting without the
overview and pushing a mode that adds it fails spectacularly.
However this is exactly what we are going to do when loading external
modes asynchronously - we'll initially use the default mode while
the modes are loading, and switch to the mode passed on the command
line when finished. So make sure that the overview UI gets initialized
properly in that case.
https://bugzilla.gnome.org/show_bug.cgi?id=689304
For now we just use it to assign an identifier to modal modes in
which we want to allow some keybindings, but we don't use it for
any actual filtering; we'll start doing this shortly.
https://bugzilla.gnome.org/show_bug.cgi?id=688202
When in the overview, if you move the mouse cursor over one of the
application launchers in the dash, all the unrelated windows are dimmed
both both in the window view and in the workspace view.
It helps to easily understand whether or not there are already opened
windows for this application, and where they are. It can also help in
differentiating the windows in the overview (sometimes the thumbnails
aren't precise enough to easily know which thumbnail belongs to which
application).
https://bugzilla.gnome.org/show_bug.cgi?id=657315
Adding a radial gradent to the dimming effect gives more depth to
the background.
Shading is computed in a GLSL fragment shader, and uses distance to
center of the screen to interpolate the darkening value to use.
