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.

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.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/23
If a source actor is set, use that for determining the arrow side (i.e.
whether the BoxPointer widget should expand in a certain direction).
This is better because it ensures that the popup is displayed on the
same monitor as the widget it originates from.
Without this, entering text with a vertically aligned input method
close to the bottom of a monitor would expand the BoxPointer downwards
on the monitor beneath it, instead of upwards, which is what one would
expect.

Any symbols (including class properties) that should be visible
outside the module it's defined in need to be defined as global.
For now gjs still allows the access for 'const', but get rid of
the warnings spill now by changing it.

This is done for properly drawing popup menu when arrow rise is 0 (in
case of background menu).
Normally, the menu with arrow rise set to 0 is drawn properly having
all four corners rounded. But when the source(click/arrowOrigin) is
near screen's edges, one of the corners (depending on source's position
and arrow alignment) is drawn right angled.
This happens because the rounded corners are skipped and right angled
arrow is drawn when arrow origin is close to the edges.(That's why when
arrow-rise is 0, it forms right angled corner).
So, a few condition checks are made to ensure that right angled corner
is not drawn.

You would think we would already do something like this, but apparently
lots of code was calling hide() without checking if the box pointer was
already visible, causing it to queue a full tween. The biggest win was
with ibusCandidatePopup.js, which called hide() on every DBus message.
This increases the performance for me to enter the overview by a tiny
bit. The remaining time is spent updating the frequent apps / all apps
display.

We must reduce the forWidth in the call to get_preferred_height()
with the border width, otherwise we might request a smaller height
that we actually need and overflow.
https://bugzilla.gnome.org/show_bug.cgi?id=696564
We need to adjust the offset of close buttons, in case the box
pointer has the arrow at the top. To do so, extend close buttons
to hook into a boxpointer (since that's the common use for them)
and automatically adjust their position.

The popup of the FolderView is now contained inside
the parent view, solving the overflow of apps with a ScrollView.
Also, solved a lot of bugs in popup/FolderView calculation
of position and size.

Commit d6cace32 introduced a typo in the left/right arrow side
calculation code that causes in most scenarios (where the monitor
width is greater then the height) to not flip the box when it doesn't
fit inside the monitor.

The arrow origin must be in the coordinate space of the box pointer,
but it cannot be calculated when the box pointer is shown, because it's
not allocated yet, so pass the source to the boxpointer and adjust
the arrow at the next paint.

Due to limitations and bugs in SpiderMonkey's GC, wrapper objects
for cairo contexts and similar may not get cleaned up immediately
after repainting, leading to leaking memory. Explicitly disposing
of such objects after they're not needed can clean up large portions
of memory for cairo surfaces.

As we may be flipping the box pointer in response to re-allocation,
like the addition of a new actor to the boxpointer, we can't queue
a re-layout while in a re-layout, so defer.
https://bugzilla.gnome.org/show_bug.cgi?id=690608
Depending on the current state of arrowSide, the box allocation may be
wrong; e.g. if the user requested a TOP, but we flipped to a BOTTOM, the
next request would look to the y2 value of the flipped BOTTOM, which is
wrong.
Instead, use the origin, plus the calculated preferred size of the box.
https://bugzilla.gnome.org/show_bug.cgi?id=690608
Make sure we re-allocate after we flip sides, to ensure that
padding around the child actor is updated correctly. Additionally,
ensure that we flip after we setPosition, as we won't get re-allocated
auotmatically by just changing the position.
https://bugzilla.gnome.org/show_bug.cgi?id=690608
Given that it's modifying state, there's no reason it can't be
using it instead. This makes it easier to use, so we aren't passing
in a bunch of instance variables every time.

Currently close() is a no-op when the menu has already been closed.
However, repeated calls could pass different animation parameters.
For instance in the user menu, we try to hide the menu immediately
before locking the screen, to avoid the popup jumping across the
screen while fading out - as we do this from the corresponding
item's activate handler, the closing is still animated if the menu's
own handler (which requests a full animation) is run first.
Fix this by changing close() to overwrite ongoing animations before
bailing out early.

If the arrow's origin is so close to the edge that the arrow will not
be isosceles, we try to compensate as follows:
- We skip the rounded corner and settle for a right angled arrow as
as shown below.

|

- If the arrow was going to be acute angled, we move the position of
the box to maintain the arrow's accuracy.

This makes sense if we want to follow what the following comment says:
// We also want to keep it onscreen, and separated from the
// edge by the same distance as the main part of the box is
// separated from its sourceActor
Using a magic number violates the "separated from the edge ...
separated from its sourceActor" part.
