Instead of using the 'y', which queues a full relayout and
thus forces effects to be reapplied, use the 'translation_y'
property, that doesn't force relayouts and allows the blur
effect to actually use the cached framebuffers a lot more.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/864
This is a moderately fast two-pass gaussian blur implementation.
It downscales the framebuffer dynamically before applying the
gaussian shader, which cuts down rendering time quite considerably.
The blur shader takes 2 uniforms as input: the blur radius; and
whether to blur vertically or horizontally.
The blur radius is treated as an integer in C land to simplify
calculations. The vertical parameter is treated as an integer by
the shader simply due to Cogl not having proper boolean support
in snippets.
At last, brightness is also added to avoid needing to use an extra
effect to achieve that. Brightness is applied in a different pipeline
than blur, so we can control it more tightly.
ShellBlurEffect also implements a "below" mode, where the contents
beneath the actor are blurred, but not the actor itself. This mode
is performance-heavy.

Since ES5, trailing commas in arrays and object literals are valid.
We generally haven't used them so far, but they are actually a good
idea, as they make additions and removals in diffs much cleaner.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/805
ES6 allows to omit property names where they match the name of the
assigned variable, which makes code less redunant and thus cleaner.
We will soon enforce that in our eslint rules, so make sure we use
the shorthand wherever possible.

xgettext got better at recognizing template strings, so we can
replace more string concatenations. Alas xgettext is still buggy
(surprise, regular expressions are hard), so there are still a
handful of holdouts that prevent us from making a complete switch.

Every since commit aa394754, StBoxLayout has supported ClutterActor's
expand/align properties in addition to the container-specific child
properties. Given that that's the only container left with a special
child meta, it's time to fully embrace the generic properties (and
eventually remove the child meta).
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/780
Remove the `this.actor = ...` and `this.actor._delegate = this` patterns in most
of classes, by inheriting all the actor container classes.
Uses interfaces when needed for making sure that multiple classes will implement
some required methods or to avoid redefining the same code multiple times.

When the screen is marked as idle, we normally start a fading animation and
a timeout to finally lock the screen. This timeout is configured using the
fade time if no longer delay is set in settings.
However if animations are disabled or slowed-down/up, the fade time is
different from the STANDARD_FADE_TIME and so we might end up showing the
lock shield without actually locking for STANDARD_FADE_TIME in the disabled
or slowed-up animations case, or locking too early in case of slowed-down
animations.
So, just adjust the timeout time using the same logic of animations so that
this value is matching all the times.

We are currently inconsistent whether to put the operators in front
of the corresponding line or at the end of the preceding one. The
most dominant style for now is to put condition and first branch on
the same line, and then align the second branch:
let foo = condition ? fooValue
: notFooValue;
Unfortunately that's a style that eslint doesn't support, so to account
for it, our legacy configuration currently plainly ignores all indentation
in conditionals.
In order to drop that exception and not let messed up indentation slip
through, change all ternary operators to the non-legacy style.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/725
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.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/716
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
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/22
For animating the arrows on the screenshield, we currently use a custom
transition function that tweens the opacity from 0 to maxOpacity in the
first half of the animation, and from maxOpacity back to 0 in the second
half.
This doesn't easily translate to Clutter's own animation framework, so
replace the custom transition with two consecutive tweens which do.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/22
The different units - seconds for Tweener and milliseconds for
timeouts - are not a big issue currently, as there is little
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.

While we aren't using those destructured variables, they are still useful
to document the meaning of those elements. We don't want eslint to keep
warning about them though, so mark them accordingly.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/627
meta_later_add() is modelled after g_idle_add() and friends, and
the handler's boolean return value determines whether it should
be scheduled again or removed. There are some places where we omit
the return value, add them (although the implicit return value of
"undefined" already gives us the intended result).
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/637
Braces are optional for single-line arrow functions, but there's a
subtle difference:
Without braces, the expression is implicitly used as return value; with
braces, the function returns nothing unless there's an explicit return.
We currently reflect that in our style by only omitting braces when the
function is expected to have a return value, but that's not very obvious,
not an important differentiation to make, and not easy to express in an
automatic rule.
So just omit braces consistently as mandated by gjs' coding style.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/608
While we have some style inconsistencies - mostly regarding split lines,
i.e. aligning to the first arguments vs. a four-space indent - there are
a couple of places where the spacing is simply wrong. Fix those.

Allow notifications to set a x-gnome-privacy-scope hint, with values in
['system', 'user']. If all the notifications in a particular source hint
that their privacy scope is ‘system’, don’t hide the notification
details on the lock screen.
This is aimed at fixing the particular case of power notifications: they
contain information which is not private to the user (it relates to the
system: battery state or AC state, which is obvious to anyone who can
see the machine), so hiding the details of a power management
notification when the screen is locked is pointless.

The last patch in the series, this one adapts StShadowHelper
to received a CoglFramebuffer. This is where we first touch
JavaScript with Cogl types, and as such, it depends on the
latest Mutter. Earlier versions of Mutter didn't have its
Mutter-Clutter GIR to generate types for various Cogl types.

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.

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.

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.
