e781e1fdba iconGrid: Create icon clones in a separate loop
For reasons not yet fully understood, `Main.uiGroup.add_actor` takes around
10 milliseconds to complete.

Because of this, each `actor.opacity = 0` has a good chance of falling
on a different frame. And when it does, `_opacityChangedId` also lands
on multiple different frames each incurring a separate relayout cycle.
It is this excessive number of relayouts that causes stuttering in the
icon grid animation (#2065). But it is the slowness of `uiGroup.add_actor`
that causes the number to be excessive when it should be one.

By creating the clones and adding them to `uiGroup` early, we then enable
the existing loop starting the animation to complete within a single frame.
And by completing within a single frame all the opacity changes land within
the same frame interval, thus incurring only a single relayout instead of
many.

This issue went unnoticed until 004a5e1042 (!704), after which the slow
emissions of `notify::opacity` became a more visible performance problem.

b5651e38c7 iconGrid: Avoid animating the same icon twice
If the icon proper has opacity of zero then that's probably because a
clone of it is animating. So avoid animating the source actor too.

And if there's any other reason for the opacity being zero, still don't
animate it because we can't see it :)

76961927d5 iconGrid.js: Animate icon spring using translation
Animating the icon spring using the `translation-x/y` properties instead
of the `x/y` properties avoids relayouts. There are still other non-icon
actors moving, but it's a big improvement.

Before: 595 relayouts per spring
After: 94 relayouts per spring

Reducing relayouts reduces reallocation, which reduces CPU-intensive
JavaScript execution.

af87bd8c87 cleanup: Use consistent style for ternary operator
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.

413c677fcf iconGrid: Only animate visible icons
Mutter recently added an optimization to only allocate
visible children [1]. That broke ClutterClones, but it
was subsequently fixed [2].

However, that exposed a third problem, this time with
FrequentView: visible but transparent icons, that are
not allocated by the icon grid, were cloned and animated
during the spring animation.

Only animate visible icons with opacity greater than 0.

004a5e1042 iconGrid: Queue a relayout after child opacity changes
We're using a vfunc override for `get_paint_volume` to exclude children
with an opacity of 0 from the paint volume and thus decrease the size of
the area we need to paint.

Now if the paint volume is requested during the spring animation (the
real icons are hidden using an opacity of 0 and clones are used for the
animation), `get_paint_volume` returns a paint volume with a height of
0. After that, the spring animation finishes and the icon-opacities are
set to 255 in `_resetAnimationActors`, and since we cache paint volumes
and there's no reason for Clutter to assume it got invalid, the icons
end up not being painted.

Fix this by queuing a relayout of the grid when the opacity of a child
is changed from or to 0, which manually invalidates the paint volume.

The reason why this is not an issue with the paginated icon grid
(all-apps view) is probably because StScrollView invalidates the paint
volume a lot more often than regular containers.

b499ca47a3 iconGrid: Restore grid actors when cancelling animations
When cancelling the animations of the icon grid, right now we simply
destroy all the clones without resetting the opacity and making the
actor reactive again. So if the spring animation to show the grid is
cancelled by pressing a key to start a search, the icon clones would be
destroyed, but the icon-opacity would still be set to 0. Now if the
Escape key is pressed, viewSelector will show the last active page (ie.
the iconGrid) without a custom animation and only fade in the page, and
because the icons still have an opacity of 0, they will be invisible.

Fix this by always restoring the opacity and reactive property of the
original actors if the animation is cancelled instead of only destroying
the clones.

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
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.

8f0e9abe47 iconGrid: Make sure the style is updated before computing the layout
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().

14d7897a93 style: Stop using braces for single-line arrow functions
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.

b4797956c7 iconGrid: Fix animation glitch
Since commit 520cea9394, the opacity of icon grid children is used
both to skip children outside the current viewport and to hide the

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.

520cea9394 iconGrid: Don't hide children inside allocation loop
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.
