ef74f922d6 background: Do not queue idle when cancelled
A cancelled cancellable means that the background was destroyed,
so we shouldn't queue an idle or emit the 'loaded' signal anymore.

dd28832dcd background: Pass cancellable when querying file info
Otherwise it is possible that the operation completes successfully
after the background has been destroyed, which will throw a warning
(caused by accessing the this._fileWatches object after it has been
nulled).

26235bbe54 js: Use (dis)connectObject()
Start using the new methods to simplify signal cleanup. For now,
focus on replacing existing cleanups; in most cases this means
signals connected in the constructor and disconnected on destroy,
but also other cases with a similarly defined lifetime (say: from
show to hide).

This doesn't change signal connections that only exist for a short
time (say: once), handlers that are connected on-demand (say: the
first time a particular method is called), or connections that
aren't tracked (read: disconnected) at all.

We will eventually replace the latter with connectObject() as
well - especially from actor subclasses - but the changeset is
already big enough as-is :-)

2b45a01517 cleanup: Use new indentation style for object literals
We have made good progress on object literals as well, although there
are still a lot that use the old style, given how ubiquitous object
literals are.

But the needed reindentation isn't overly intrusive, as changes are
limited to the object literals themselves (i.e. they don't affect
surrounding code).

And given that object literals account for quite a bit of the remaining
differences between regular and legacy rules, doing the transition now
is still worthwhile.

5442266f28 js: Simplify promisify() calls
If the finish function isn't specified, promisify will now try

5c550daecb backgroundManager: Always emit 'loaded' signal
As backgrounds are cached, it is possible that we never emit the
'loaded' signal added in commit f386103bc1. We are relying on the
signal though, so do the same as Background and emit the signal
from an idle if the background was already loaded.

f386103bc1 Delay login animation until after wallpaper has loaded
Currently, the login animation can occur before the user's wallpaper has
been loaded. When this happens, we wind up displaying a solid blue
background for half a second or so before the proper background is
displayed. This looks jarring and bad. It's great that we can start
GNOME quickly, but starting up before the wallpaper is ready is *too*
quickly.

I've been meaning to fix this since 2014. Better late than never! We can
just have BackgroundManager emit a loaded signal the first time it loads
its first background, and have the startup animation code wait for that
before proceeding.

Some of this code is by Florian, who helped with promisifying. Thanks!

Modifying variables from an outer scope in functions created in a loop
is considered problematic by eslint, because the variable value in the

c7e0c7eb79 background: Rename Background 'changed' signal to 'bg-changed'
Meta.Background has already a 'changed' signal and not to confuse the source
signal with the wrapper one, rename the wrapper class signal into 'bg-changed'.

This will be relevant when we'll inherit from Meta.Background, as signal
emissions from the base class could interfere with the wanted derived class
behavior and with the the grouping of successive changes into a single ::change
emission.

451f4e3636 cleanup: "Only" use two indentation styles for object literals
We currently use no less than three different ways of indenting
object literals:

    let obj1 = {
        foo: 42,
        bar: 23,
    };

    let obj2 = { foo: 42,
                 bar: 23 };

    let obj3 = { foo: 42,
                 bar: 23
               };

The first is the one we want to use everywhere eventually, while the
second is the most commonly used "legacy" style.

It is the third one that is most problematic, as it throws off eslint
fairly badly: It violates both the rule to have consistent line breaks
in braces as well as the indentation style of both regular and legacy
configurations.

Fortunately the third style was mostly used for tween parameters, so
is quite rare after the Tweener purge. Get rid of the remaining ones
to cut down on pre-existing eslint errors.

0846238f69 js: Use implicit animations for animatable properties
We now have everything in place to replace Tweener for all animatable
properties with implicit animations, which has the following benefits:

 - they run entirely in C, while Tweener requires context switches
   to JS each frame

 - they are more reliable, as Tweener only detects when an animation
   is overwritten with another Tween, while Clutter considers any
   property change

476816732f cleanup: Use milliseconds for animation times
The different units - seconds for Tweener and milliseconds for

overlap. However this will change when we start using Clutter's
own animation framework (which uses milliseconds as well), in
particular where constants are shared between modules.

In order to prepare for the transition, define all animation times
as milliseconds and adjust them when passing them to Tweener.

7059e31f6a background: Group 'changed' signal emission
Background is monitoring the whole `org.gnome.desktop.background` gsettings keys
for changes connecting to the non-specialized 'changed' signal and re-emitting
this as-is.
This means that when the background is changed via control-center, we get
multiple 'changed' signal events from GSettings, and for each one of this we
recreate a Background and a BackgroundActor.

Avoid this by using an idle to delay the emission of the 'changed' signal
grouping the events.

The same Meta.Background could be used by multiple instances of background

Instead of calling `run_dispose` directly on it, just nullify the reference

gabage collector that keeps the proper reference count on the Meta.Background.
