f09fbb19cf iconGrid: Merge PaginatedIconGrid and IconGrid
Now that the only user of the IconGrid is AppDisplay, and
it only uses the paginated icon grid, there's no point in
having the two classes split anymore.

In addition to that, future commits will introduce a layout
manager that will extend current icon grid features, and
merging PaginatedIconGrid and IconGrid in the same class will
vastly simplify this transition.

Merge PaginatedIconGrid into IconGrid, and adapt AppDisplay
to this change.

402fd8ec29 iconGrid: Downscale icon size when comparing to defaults
The return value of st_theme_node_lookup_length() is scaled according
to the scale factor. IconGrid.ICON_SIZE is not. However, when BaseIcon
tries to fetch the CSS value for "icon-size" (which returns a scaled
value), it uses it as-is, mixing the two coordinate systems.

Use a single coordinate system (unscaled sizes) in IconGrid.BaseIcon.

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

own animation framework (which uses milliseconds as well), in

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

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.

0e0574a0b4 iconGrid: Eliminate JavaScript for painting/picking
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.

Performance on an i7-7700:

Moving the cursor over the icon grid:
Before: 70% CPU, 5.5ms per frame
After : 60% CPU, 4.5ms per frame

Scrolling the icon grid:
Before: 60% CPU, 4.4ms per frame
After : 50% CPU, 3.3ms per frame

1acdff822a iconGrid: Keep icons reactive during pulse animation
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.

a5e6dd52d2 iconGrid: Defer and group animation cleanup
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).

iconGrid: Stop using Shell.GenericContainer
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.

baseIcon: Stop using Shell.GenericContainer
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.

3b1330880f cleanup: Use Function.prototype.bind()
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.

63efe1db11 iconGrid: Don't use clones for pulse animation
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.

Following design decision, we want to animate AllView and FrequentView

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.

28c1f81f4a appDisplay: Make page panning smoother on touch
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.

792b963bda iconGrid: Change IconGrid.addItem() to take an object instead of an actor
IconGrid has never really been a general purpose container, but has
always been used in conjunction with BaseIcon. IconGrid will soon
gain the ability to adjust the item size dynamically to adapt to the
available space, which will require that we can make some more
assumptions about the items added to the grid (namely: we need
access to BaseIcon's setIconSize() method).
So change addItem() to take an object instead, which should have
an actor and a (BaseIcon) icon property.
