We have been using type-safe comparisons in new code for quite a while
now, however old code has only been adapted slowly.
Change all the remaining bits to get rid of another legacy style
difference.

Start using the new methods to simplify signal cleanup. For now,
focus on replacing existing cleanups; in most cases this means
signals connected in the constructor and disconnected on destroy,
but also other cases with a similarly defined lifetime (say: from
show to hide).
This doesn't change signal connections that only exist for a short
time (say: once), handlers that are connected on-demand (say: the
first time a particular method is called), or connections that
aren't tracked (read: disconnected) at all.
We will eventually replace the latter with connectObject() as
well - especially from actor subclasses - but the changeset is
already big enough as-is :-)

We currently use get_color(), which assumes the color exists in the
stylesheet (and prints a warning if it doesn't).
Switch to lookup_color() and skip filling the background if no
such colors exits.

We want to mute things like pointers hovering the BoxPointer while
it does open. However keyboard events should still be handled
promptly.
Since Clutter.grab() will involve different actors being grabbed
and focused, this will have some more presence, e.g. when navigating
panel menus. We want to be able to navigate outside a menu while it
is still being shown.

Some popovers like the ibus candidate popover may be requested while
showing an unredirected fullscreen window. Disable unredirection
while the popover is visible so that it can actually be shown.

It's important to update the allocation of the parent before allocating
its children, it's an assumption we make in a lot of places.
This broke resource scale calculation for boxpointers and their
children when multiple monitors with different scales are used and the
primary monitor is not positioned at x=0, y=0.

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.

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.

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.

Since the repositioning is now done during allocation, we can just queue
a relayout when setting the boxpointer positioning via the source actor.
As per this _relayout() and _updateFlip now needs to be called during allocation
only and with an allocation box set.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/576
Changing the arrow side might need to reposition the boxpointer, however
if this happens during allocation, we don't need to trigger a new relayout since
we'd set the new allocation once _updateFlip's _reposition call is terminated,
otherwise if the position has changed, changing the boxpointer coordinates
will trigger a relayout anyways.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/576
As per commit 044572cb60 boxpointer uses its own coordinates to position itself.
However this would lead to warning when mutter-clutter is compiled with debug
options as we'd might try to set the box coordinates during the allocation
cycle.
So, when calling _reposition during allocation, instead of setting the actor's
coordinates we just pass the allocation box and we adjust its origin, in order
to set it properly in the vfunc.
Fixes https://gitlab.gnome.org/GNOME/gnome-shell/issues/1382https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/576
Compute the source actor workarea and allocation when repositioning and keep it
cached so that we've not to calculating it again in _calculateArrowSide.
Since _calculateArrowSide only is called inside _updateFlip that is always
called just after reposition, we can be sure that the computed values are still
correct.

Currently all the widgets using BoxPointer and so popup actors are always drawn
at screen origin and then shifted at paint time in the proper position.
This doesn't work when using resource scale, since the widgets need to know
in which monitor they currently are in order to use properly scaled resources.
So, basically revert commit 22c22e0d7 and go back using the actual actor
coordinates for positioning and the actor translation for animating it, as the
relayouting issues of the past seem to be gone now.

Because we're late in the cycle, and don't know how many
extensions actually rely on this API, this commit adds
back the BoxPointer.show() and .hide() functions, with
warning messages to notify consumers that this is going
to be removed.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/153
Pretty much like dd4709bb2, BoxPointer's show() and hide()
functions will clash with Clutter.Actor's ones.
In addition to that, on a conceptual level, the current API
is not great, because calling boxPointer.hide() won't result
in boxPointer.actor.visible == false.
For these reasons, rename show() and hide() to open() and
close(). A compatibility layer will be added in a following
commit, warning about the usage of show() and hide().
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/153
Flag some actors that are good candidates for caching in texture memory
(what Clutter calls "offscreen redirect"), thereby mostly eliminating
their repaint overhead.
This isn't exactly groundbreaking, it's how you're meant to use
OpenGL in the first place. But the difficulty is in the design of
Clutter which has some peculiarities making universal caching
inefficient at the moment:
* Repainting an offscreen actor is measurably slower than repainting
the same actor if it was uncached. But only by less than 100%,
so if an actor can avoid changing every frame then caching is usually
more efficient over that timeframe.
* The cached painting from a container typically includes its children,
so you can't cache containers whose children are usually animating at
full frame rate. That results in a performance loss.
This could be remedied in future by Clutter explicitly separating a
container's background painting from its child painting and always
caching the background (as StWidget tries to in some cases already).
So this commit selects just a few areas where caching has been verified
to be beneficial, and many use cases now see their CPU usage halved:
One small window active...... 10% -> 7% (-30%)
...under a panel menu........ 23% -> 9% (-61%)
One maximized window active.. 12% -> 9% (-25%)
...under a panel menu........ 23% -> 11% (-52%)
...under a shell dialog...... 22% -> 12% (-45%)
...in activities overview.... 32% -> 17% (-47%)
(on an i7-7700)
Also a couple of bugs are fixed by this:

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.
