In some cases the style-changed signal hasn't been emitted when
_computeLayout() is called, resulting in the use of the default spacing
and item size values for the calculations.
One case where this happens is when starting a search. Right after the
initialization of GridSearchResults, _computeLayout() is called from
_getMaxDisplayedResults() and the style-changed signal hasn't been
emitted yet. The computed layout will be wrong and the maximum
number of results will also be wrong.
To prevent this from happening, make sure the style has been updated
before doing the calculations in _computeLayout().

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.

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.

We are currently inconsistent on whether case labels share the same
indentation level as the corresponding switch statement or not. gjs
goes with the default of no additional indentation, so go along with
that.

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.

Since commit 520cea9394, the opacity of icon grid children is used
both to skip children outside the current viewport and to hide the
real icons while animating icon clones.
As a result, a grid animation during an animation now ends up showing the
icons that are being animated. Avoid that glitch by leaving children's
opacity alone when there's an ongoing animation.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/582
Hiding a child implies a parent reallocation, and IconGrid does it for the
children that doesn't fit in the available space, but this could lead to an
allocation recursion cycle. This has been introduced by commit 0e0574a0 to
reduce CPU usage not to using JS vfuncs.
To avoid this, toggle the children opacity instead so that we can achieve the
same visibility result, without any reallocation need.
In this way we also fix the case where hidden children can be shown again,
as _getVisibleChildren doesn't filter-out transparent ones, restoring the
pre-commit 0e0574a0 behavior.

Since version 1.50.0, gjs defines GObject.NotImplementedError for throwing
errors when a "virtual" method that requires a subclass implementation is not
defined.
So use this instead of a generic JS Error in such cases.

This is a purely accessory change in terms of X11 Display usage cleanup,

Just like the "in" operator in the previous patch, "instanceof" has
a lower precedence than negation, resulting in the nonsense condition
of "true instanceof BaseIcon".
Add parentheses to get the intended behavior.

The only reason for `vfunc_paint` and `vfunc_pick` existing was to
implement a culling optimization. Although that optimization actually
made performance worse than none at all because it forced the painting
and picking cycles to spend more time calling into JavaScript.
Turns out we don't have to choose between native code and culling though.
Just reimplement the culling using native ClutterActor functions and we
get the benefits of both.

The `reactive` property of icon actors was being restored multiple times
over the course of the pulse animation, all at slightly different times
as each icon finished animating at different times.
The problem is that toggling `reactive` on an `StWidget` incurs a style
change of the `insensitive` pseudo class, and style changes would quickly
queue relayouts incurring full stage reallocation. This occurred many times
during a pulse animation, limiting its smoothness and performance.
The solution is to not toggle the `reactive` property in the pulse
animation at all, which avoids incurring multiple full stage relayouts.
As a bonus, this means the icon under the cursor pulses with the correct
selection highlight, appearing more seamless and responsive.

The `reactive` property of icon actors was being restored 24 times over
the course of the spring animation, all at slightly different times as
each icon finished animating at different times.
The problem is that toggling `reactive` on an `StWidget` incurs a style
change of the `insensitive` pseudo class, and style changes would quickly
queue relayouts incurring full stage reallocation. This occurred many times
during a spring animation hogging the CPU and limiting the frame rate.
The solution is defer and batch the cleanup for all icons until after the
last icon has finished animating. This way the CPU impact of the style
change and stage relayout isn't felt during the animation so the frame
rate remains higher and smoother. The overall CPU usage of the animation
is also reduced as the remaining relayouts are much more likely to be
grouped into a single frame.
Icon spring animation performance on an i7-7700:
Before: 83% CPU and 47 FPS
After : 78% CPU and 54 FPS
which is about a 22% increase in performance per clock (FPS/CPU).

Removing Shell.GenericContainer from the IconGrid class was
challenging because it needs the "skip paint" API from it.
This API was added, too, as a workaround to the inability
to override vfuncs from GJS.
The overrides are largely copy-pasted and translated versions
of the Shell.GenericContainer code.
The IconGrid:key-focus-in signal was renamed to :child-focused
to avoid clashing with ClutterActor:key-focus-in.
In GridSearchResults, the internal IconGrid had it's y_expand
set to false, so it doesn't push other search elements (the
list results mainly) to the bottom of the screen.
Because skip paint wasn't and still isn't a GObject property,
rename it to _skipPaint to reflect that.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/153
As part of our quest to obsolete Shell.GenericContainer, IconGrid will
become a Clutter.Actor subclass. As the ::key-focus-in signal would
clash with Clutter.Actor::key-focus-in, rename it to ::child-focused.

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.

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.

We now cancel animations on override, however we also want to cancel
animations altogether on unmap (that is, when hiding the overview)
to avoid icons swarming into the void.

Until now we were waiting the animation to complete to allow the user to
make a new animation. This could bring some problems and annoy nervous
users.
Instead of that, destroy clones on new animations triggers and
create a new animation with the new direction.

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

Currently we use the same amount of total delay divided by all items,
but that makes the items animate slow if the amount of items is small.
To avoid that, use a smaller total amount delay for an amount of items
smaller than four.

The spring animation has to use clones to escape any clip set on the
parent, as it mainly occurs outside the parent. The same does not apply
to the pulse animation, which is very much in place - in fact, if the
parent is clipped (for instance a scrolled app folder), not having the
clip applied to the animated icons is indeed wrong.
Just animate the original grid actors instead, which gives the expected
result.
https://bugzilla.gnome.org/show_bug.cgi?id=736885
Commit 9e5704b introduced a regression due to a sloppy mistake not
making actors reactive on animation out.
Fix that making actors reactive when animating out as well.
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.
Although the actor are with opacity 0, they were reactive, so the if the
user quickly make a click on the grid while animating it can launch an
app accidentally.
To avoid that make the actors non reactive while animating.
Following design mockups, animate the icons on AllView, FrequentView,
Dash and Search to zoom out when opening a new window of the app or when
the app is not running and the user execute it.

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.

The scale passed to _updateChildrenScale is exclusively computed from
properties, so it can be moved into the function itself - as the scale
now becomes a mere detail, rename to a more appropriate _updateIconSizes
at the same time.
Currently, our logic for page panning isn't great. If the user starts a
pan upwards and hesitates over a new page, we'll go to the *next* page
on release, since the difference is greater, but the velocity wound down
to 0.
Instead of trying to treat it like page down or scrolls, simply do the
math to find the page where the user scrolled to.
This is unfortunately broken for fast swipes, since the user doesn't get
far enough into the new page to make a difference. I'm getting the
impression we'll need a gesture recognizer for this, though, however
crude. Simple hacks I tried, like a velocity multiplier, didn't work
properly.
