Sometimes when an icon is dragged and dropped in Dash, one Favourite app icon
can appear to the right of Dash separator. This can happen when available system
resources are low and the PlaceHolder destroy animation is delayed and the
corresponding container child is still present. With this commit the separator
position is calculated correctly, even when the animation is pending.

Back when the Dash was vertical, the size of each item was calculated
solely based on the available height. After making the Dash horizontal,
this was swapped by the available width. However, when the height of the
Dash decreases, the current code results in never scaling them up ever
again.
Fix that by making ControlsManagerLayout explicitly pass the maximum Dash
sizes. Remove the 'notify::width' handler that served the same purpose.

The children variable holds the icons that were originally in
the dash. For the separator visibility, we should consider the
icons that are in the dash after the update, so we must consider
additions as well as removals.

Only the area used by favorite apps can be used as drop targets, it
is not possible to add new favorites between the running apps at the
end. While that behavior makes sense, it is currently impossible to
distinguish the two areas with confusing results.
Address this by adding a visual separator between favorites and
running apps.

We use a custom actor to make sure that the show-apps button remains
visible even when there's not enough space to show all icons.
We can achieve the same result with much less code, by using a custom
BoxLayout layout manager for the icons to override the minimum width.

Now that the Dash is horizontal, the popup menu of the Dash icons must
show up, instead of left/right.
Make AppIcon.popupMenu() receive an optional parameter with the side
to show the menu, using St.Side.LEFT as default. Override this method
in DashIcon to always pass St.Side.TOP.

And move it to the bottom of the overview. Change the height-based calculation
of the icon sizes to be width-based. Put the DashFader in a vertical box, and
make all corners of the Dash equally rounded.

When checking for a suitable icon size, Dash currently checks which
of the hardcoded icon sizes is smaller than the calculated available
size.
On some circumstances, however, when the calculated available size
is exactly equal to the hardcoded icon sizes, Dash selects a smaller
size. This cascades (the next icon size is exactly the smaller size,
etc) and ends up with always Dash selecting smallest size available,
even with plenty of available space.
Check if the calculated available size is smaller or equal to the
hardcoded icon sizes.

Commit ff3d32dd18 added a custom DashIcon subclass that disables
all DND methods from ancestors, including canceling the context
menu timeout and emitting the overview's item-drag-begin signal.
All we want is opting out of the parent's scale-and-fade behavior,
so override those methods instead.

This reverts commit c0c027c608. Because for
some reason animating external opacity and position is still incurring
internal repaints, which disables offscreening and makes fading of
overlapping actors look wrong. `ON_IDLE` should be fixed in mutter before
it is used (in boxpointer at least) again.
Fixes https://gitlab.gnome.org/GNOME/gnome-shell/issues/2270
To bypass offscreening in cases where continuous animation is happening.
Offscreening is slower in such cases so this reduces the render time of
animations within offscreenable actors.
On an i7-7700 this reduces the render time of boxpointers for example by
25-30%.

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.

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.

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.
