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.

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.

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.

Because the Dash icons are not drop targets themselves,
add a tiny DashIcon class, which is an AppDisplay.AppIcon
subclass, and disable all DND drop code from it.
Show a folder preview when dragging an app icon over another
app icon.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/671
As per design direction, scale and fade the app icon
when starting dragging it, and show it again if the
drop is accepted. Clutter takes care of animating the
rest of icon positions through implicit animations.
Scale and fade the dragged icon while it's being dragged.

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
Dash items are currently animated via the custom "childScale" and
"childOpacity" properties. However since commit efb3025d8c, those
properties actually control the scale-x/scale-y and opacity properties
of the actor itself (not the child), so cut out the intermediate
custom properties in favor of the "real" ones.
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.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/663
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.
Spotted by eslint.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/608
When destructuring multiple return values, we often use trailing commas
to indicate that there are additional elements that we are ignoring.
There isn't anything inherently wrong with that, but it's a style that's
too confusing for eslint - on the one hand we require a space after a
comma, on the other hand we require no space before closing brackets.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/607
We can use that newer method where we don't care about the actual position
of an element inside the array.
(Array.includes() and Array.indexOf() do behave differently in edge cases,
for example in the handling of NaN, but those don't matter to us)
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/152
When determining the biggest icon size that fits the available height,
we first subtract the additional space requirements of icons (spacing,
padding, running indicator etc.) and then divide the result by the
number of icons to get the maximum size available to each icon texture.
In the above, the additional space requirement of each icon is taken
from the first icon (as all icons are assumed to be the same), and
calculated as the difference between the icon button's preferred height
and the currently used icon size.
To make sure that the icon is actually using the dash's current icon
size (even while animating to a new icon size), we enforce its height
during the size request and restore its original height afterwards.
However after some recent changes, that step is causing troubles:
For some reason, the original height may be 0, and when we restore it,
we end up forcing a fixed non-height that bypasses the regular size
request machinery.
While it is unclear where exactly the zero height comes from (maybe
waiting for a valid resource scale?), it is clear that it's best
to avoid forcing a fixed height. So instead of making the icon
texture comply with the assumed icon size, adjust the calculations
to use its current height request.

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.

Destroy the DashItemContainer's child from the same handler as the tooltip. This
will prevent invalid reads when the item is destroyed while its quicklist is
still open.
Fixes: https://gitlab.gnome.org/GNOME/gnome-shell/issues/781
DashItemContainer currently animates the scale and opacity
of its child when zooming in. This is visible when adding
a new favorite item to the dash; the items will zoom in from
the center.
After the previous commit, however, the zoom animation got
slightly broken, and looked like the icon was coming from
the bottom instead of the center.
Fix that by setting the scale and opacity of DashItemContainer
itself, instead of its child. Remove the unused code after that
too.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/153
Pretty much like the previous patches, this extends St.Bin. The
most interesting aspect of this patch is that most of the sizing
routines of the icons is now delegated to the actors and layout
managers, removing quite a bunch of code.
The 'spacing' theme property is now redirected to StBoxLayout's
spacing property. Also adjust the Dash code to stop forcing a
potentially invalid width in the first icon too.

Flag some actors that are good candidates for caching in texture memory
(what Clutter calls "offscreen redirect"), thereby mostly eliminating
their repaint overhead.
This isn't exactly groundbreaking, it's how you're meant to use
OpenGL in the first place. But the difficulty is in the design of
Clutter which has some peculiarities making universal caching
inefficient at the moment:
* Repainting an offscreen actor is measurably slower than repainting
the same actor if it was uncached. But only by less than 100%,
so if an actor can avoid changing every frame then caching is usually
more efficient over that timeframe.
* The cached painting from a container typically includes its children,
so you can't cache containers whose children are usually animating at
full frame rate. That results in a performance loss.
This could be remedied in future by Clutter explicitly separating a
container's background painting from its child painting and always
caching the background (as StWidget tries to in some cases already).
So this commit selects just a few areas where caching has been verified
to be beneficial, and many use cases now see their CPU usage halved:
One small window active...... 10% -> 7% (-30%)
...under a panel menu........ 23% -> 9% (-61%)
One maximized window active.. 12% -> 9% (-25%)
...under a panel menu........ 23% -> 11% (-52%)
...under a shell dialog...... 22% -> 12% (-45%)
...in activities overview.... 32% -> 17% (-47%)
(on an i7-7700)

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.

Since commit ef1e27966d turned DashItemContainer into an StWidget,
the destroy() method overrides the ClutterActor method, which is at
the very least bad style. Instead, follow the usual pattern of using
a ::destroy handler.
https://bugzilla.gnome.org/show_bug.cgi?id=791233
Labels are currently destroyed from both animateOutAndDestroy()
and destroy(), which now (rightfully) triggers a gjs warning. As
the label is created unconditionally since commit 36e5ae4a25,
mirror that and always release it in destroy() and hide it
elsewhere.
https://bugzilla.gnome.org/show_bug.cgi?id=791233
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.
https://bugzilla.gnome.org/show_bug.cgi?id=785084
We currently use "array[index]" to test whether an array has an
element at index before using it. However nowadays gjs warns about
accessing non-existent array elements, so the test itself already
produces a warning. Avoid this by checking the array length before
using an index to access an element.
https://bugzilla.gnome.org/show_bug.cgi?id=781471
StIcon will skip loading the texture when its theme node is unset (which
may happen on style changes while the widget is hidden). While our size
request to compute the dash icon size will create the icon's theme node
if necessary (and of all its parents), a missing texture can still throw
off our computation.
Make sure this doesn't happen by ensuring the icon's style first, so the
texture is updated in response to StWidget::style-changed if necessary.
https://bugzilla.gnome.org/show_bug.cgi?id=745649
When adjusting dash icon sizes, we compute the icon padding by subtracting
the configured icon size from the first icon actor's preferred size. To
make sure that the preferred size correctly corresponds to the current
dash icon size even while the icon is animating, we enforce the size
before the size request. For that we used to temporarily manipulate
the icon texture size directly, but commit e92d204d42 cleaned this
up to use the setIconSize() method instead.
This does not work however, as the icon actor's iconSize property will
always match the dash iconSize property, making the method a noop. So
go back to the original approach of enforcing the texture size to make
sure we always base our computations on correct values.
https://bugzilla.gnome.org/show_bug.cgi?id=745649
The overview has a longer life-time than dash items, so we are
leaking a signal connection each time an item is destroyed.
