If we are transitioning the label from 0 to its natural height, we
must set natural-height-set again after querying the preferred height,
otherwise Clutter would skip the transition.
However when transitioning in the opposite direction, setting the
property to true can go horribly wrong:
If the actor hasn't been allocated before, it will store a fixed
natural height of 0. But as there is no fixed min-height, we can
end up with min-height > natural-height, which is a fatal error.
(This isn't an issue when *actually* setting a fixed height, as
that will set both natural and minimum height)
So instead of always setting natural-height-set to true, restore
its previous value to fix the issue.

repeatCount and autoReverse don't play well with animations disabled:
They cause password entries to wiggle themselves off-screen (by ending
up with some off-scale translation-x value).
While we should handle this more gracefully in the transition helpers,
it also makes sense to handle the case directly in wiggle(): As it
uses a chain of three transitions, we would still end up with a crude
one-frame-per-transition wiggle "animation".
Instead, do no animation at all as you would expect when animations are
disabled.

Now that we apply a strong blur effect to the background, it doesn't
make too much sense to use a separate lock-screen background: It will
be mostly unrecognizable anyway.
The alternative would be to turn off the blur effect if a different
background is used (or have a hidden setting for that), but that would
then imply that we must keep the contents readable without blur.
Let's avoid that rabbit hole and just re-use the regular background.

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%.

`-slider-handle-radius` is a floating point value and even in the default
theme it's not a whole number. Regardless of the fractional part that's
still going to occupy a whole extra pixel with antialiasing. So make room
for it. Otherwise it looks clipped, which it is by the Cairo context of
its `StDrawingArea`.

Unused at the moment, but add the plumbing so that default key
definitions may specify symbolic icons that will be shown instead
of the text.
This is intended to replace the use of CSS and background-image
to handle those buttons with an icon.

While the gsetting is available for all who needs it, the Shell might
override it given various hueristics. Expose the decision made by the
Shell via a new property.
Intended to be used by gsd-xsettings as well as xdg-desktop-portal-gtk.
This also add a version property to the API, so that semi external
services (xdg-desktop-portal-gtk) can detect what API is expected to be
present.

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.

Now that the bind constraint changes the preferred size of
the actor, a major flaw in the AppDisplay code was exposed:
the folder dialog depends on the preferred size of a parent,
and the parent depends on the preferred size of the folder
dialog.
While we know this is not actually true, we shouldn't rely
on broken behavior to achieve this result. What's interesting
is that the bind constraint used by the folder dialog is a
relic of the development phase; we now control the position
and size of the dialog with a combination of CSS, and alignment.
Remove the unnecessary bind constraint.

Since the design of the notification popup changed with the theme
refactor and there are now boxes around the world-clock and weather
sections, the overlay scrollbar that is shown above them looks rather
bad. So simply hide that scrollbar, we still have the vfade effect to
indicate the container is scrollable and we also depend on that in the
new popup app-folders.

Make sure the stylesheet properties of the window-chrome title are
updated before requesting the preferred width of the title to prevent
size changes of the title after we animated the width.
