When selecting the best icon size for the available area, we
iterate from the biggest icon size to the smallest one, and
stop when finding a size that fits the available area.
However, the 'bestSize' variable is only updated when the
available area is positive. This is problematic in super bad
cases like when none of the icon sizes actually fit the availabe
area, which was hit with a previous iteration of this branch.
Make sure to update the best size while iterating, so that the
smallest size is selected even in such bad cases.

Use the Clutter.ActorAlign.FILL alignment by default, which
expands the grid until max-row|column-spacing is hit. This
was the behavior we originally wanted for the icon grid, and
it's finally being realized.

This is a new property to control the padding around each page,
as opposed to the padding around the entire container.
Following the original design of IconGridLayout [1], changing
the page-padding property doesn't trigger relayouts; the container
is responsible for queueing a relayout appropriately.

IconGridLayout uses the biggest minimum size to allocate its
children. Next commit will make app icons with long names show
not ellipsize on hover, and it is important that the icon itself
is able to follow that.
Use preferred size if it's bigger than the minimum size.

This new public API moves items without removing and readding
them, which allows us to avoid some tricky behavior. Noticeably,
following the original design described at 3555550d5, the new
IconGridLayout.moveItem() method does not call `layout_changed`.
This is done by IconGrid itself, queueing a relayout.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1447
When the last item of an IconGridLayout page is removed,
the page itself is removed too. However, the indexes of
items of next pages are not updated, which mess up the
layout manager state.
Update the page index of the items at forward pages when
removing a page.

The icon grid is always paginated, so the app grid code doesn't need
to behave differently in the FolderView and AppDisplay.
Move the keyboard handling to IconGrid itself, and remove the now dead
code from AppDisplay.

The new icon grid layout operates based on rows and columns, and
doesn't try to dynamically adapt it to fit to the container. In
this case, it is better to have a pre-defined set of well-known,
well-tested rows and columns, and switch between them based on
the aspect ratio of the screen.
Introduce a set of modes to the icon grid, and select the mode
that is closest to the aspect ratio.

IconGridLayout is a new layout manager that aims to replace the
current paginated layout algorithm implemented by the icon grid.
There are a few outstanding aspects of this new layout manager
that are worth highlighting. IconGridLayout implements all the
mechanisms necessary for a paginated icon grid, but doesn't
implement any policies around it. The reason behind this decision
is that this layout manager will be used by other places (e.g.
the login dialog) that demand different policies to how the
grid should look like.
Another important aspect of this grid is that it does not queue
any relayouts when changing its properties. If a relayout is
required, the actor should manually queue it. This is necessary
to avoid layout loops.
Add the IconGridLayout class. Next commits will do the surgery
to IconGrid and any related code to use this new layout manager.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1271
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.

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.

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.

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 :)
Closes: https://gitlab.gnome.org/GNOME/gnome-shell/issues/2167
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.

We don't want the icon to fill extra space, so set the alignment
accordingly. Otherwise we get an unexpected result when adding
a background just to the icon part (as far as I can tell: just
system-action-icon).

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.

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.

Add a `animateLaunchAtPos()` method to the AppIcon class to animate the
launch of an app at a given position. This allows for a visual
indication of whether dropping an app icon using DnD was successful at
the position the drop happened in a later commit.

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.

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.
Fixes https://gitlab.gnome.org/GNOME/gnome-shell/issues/1502
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.

After dropping an application into the folder icon, the
list of applications is updated but the folder icon itself
is not.
Introduce BaseIcon.update() and call it from FolderIcon
when redisplaying.

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
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.
