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.

Remove the default icon size of -1 and always set the container StBin to
a real size. This fixes an error where the "width" and "height"
properties get set to -2 (which is -1 * scaleFactor) in the `_init`
function.

To make sure the GC really disposes the KeyboardController object we
need to remove all references to the object, which means we have to
disconnect signals the object connects to, too.
This also fixes a bug where keys remain pressed forever and thus also
break that key on real keyboards. It happens if the OSK gets destroyed
during an OSK-key is being held so the StButton of the key is not
released. That means the key remains pressed in the
MetaVirtualInputDevice that we are now leaking because
KeyboardController isn't garbage collected.

xgettext gained some support for template strings, and no longer
fails when encountering '/' somewhere between backticks.
Unfortunately its support is still buggy as hell, and it is now
silently dropping translatable strings, yay. I hate making the
code worse, but until xgettext really gets its shit together,
the only viable way forward seems to be to not use template
strings in any files listed in POTFILES.

Since quite a few strings of dialogs provided by external programs are
not updated yet and the string freeze is already in effect, make sure we
don't break those dialogs by stripping aways large parts of the
headline.
To do that, detect if the title label is larger than the available width
and if it is, switch to a smaller font-size of 13pt. This makes sure we
still show about the same number of characters in the headline as we did
in previous releases.

With the old screen shield, we were simply hiding the lightboxes to show
the shield when the user became active after activating the shield but
before locking the screen (that is, when using a lock-delay).
However now that the shield is gone, we end up showing the unlock dialog
even though we are not actually locked.
We probably don't want to add back a shield-like mode (that is, a way to
raise the unlock dialog without authentication when we aren't locked),
so just deactivate the whole shield when the user becomes active again
before the lock kicks in.

The design team discussed the ellipses at the end of the hint text of
our entries and, even though they are present in most mockups, it turned
out they don't like them, so remove them.
It also turned out they don't like the prefixes like "Enter" before it,
so remove those, too.

With the new dialog design the descriptions of entries are now
implemented as hint-text of the StEntry. That means the colon at the end
of the descriptions no longer makes sense and should be removed.

Currently separators get all the padding from regular menu items,
which is excessive for non-interactive elements.
Shuffle style classes around a bit to allow overriding the normal
padding for separators.

Shift, caps-lock and friends change the capitalization of following
key presses. It is unexpected for those keys to have side-effects,
so don't switch to the prompt when they are pressed.

We don't want to show a caps-lock warning when showing a non-password
entry, but we also don't want the layout to jump when changing the
label's visibility.
Achieve that by inserting an empty placeholder label that we can
show whenever the caps-lock warning is hidden.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/2215
The promptBox is initially fully opaque, so showing it before the
transition can result in a brief flash before fading in.
Just remove the show() call and let the transition handle the
visibility.

Usually, logging in or unlocking the session is made asynchronously,
and AuthPrompt properly manages which entry is currently visible.
External code don't rely on any specific entry to be set, since it
is AuthPrompt's responsibility to select the correct one to be shown.
However, there's one specific case where AuthPrompt must preserve
the password entry: on reset. The reset code preserved whatever
entry was currently displayed, but after fe69dacaf1, it always
changes to the username entry.
Make sure to show the password entry on reset.

In the past, the session menu button was part of the auth prompt widgetry,
so we didn't have to manually hide it when showing the user list. However,
now it is part of the login screen itself.
Hide the session menu button when the user list is shown.

In the common case where we only have a single unread notification
from a particular app, the count doesn't add useful information.
Reduce clutter a bit by only showing the notification count if we
have at least two.

Clicking or typing to reveal the auth prompt are good options for
mouse/keyboard workflows, but awkward on touch devices. Now that
we have SwipeTracker, adding corresponding gestures support is
easy, so do just that.

The current transition between clock and auth prompt uses a simple
crossfade.
"What kind of spatial model is that?!"
T.B.
Root the transition a bit more by adding translation and scale to
the animation.

Hiding the Caps lock warning label changes the layout of
Auth Prompt. This is specially noticeable when logging in
with unlisted users, where we change the visibility of this
label after typing a username, and the whole user widget
moves a bit.
Change the Cap lock label's opacity instead of hiding it.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/922
Currently, when a null user is passed, we don't add any
username label. That makes the layout of user and no-user
cases inconsistent.
Add a ghost label with no opacity to mimic the username
label.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/922
Currently, AuthPrompt is connecting to its own 'next' signal
signal to react to any of the entries being activated, and do
some actions like starting the spinner and answering the PAM
question.
Refactor this code into another method, and don't connect to
our own signal.

Unfortunately, the question that is displayed comes directly
from PAM. It usually is just "Password:", which comes from
pam-unix, but other questions can be set, usually with the
colons, since they are crafted with a CLI workflow in mind.
Manually drop the colons from questions asked by PAM. This
is also done by the PolKit agent, which shows how the stack
is fragile, but it's what we have for now.

This is a regression from the transition to password entry. Both
entries need to be connected to the relevant signals, otherwise
username-based login won't ever work.
Connect both the text and the password entries.
