When a window is being resized by the compositor, with Wayland the
compositor first asks the window to change its size and emits the
"size-change" signal, and then emits the "size-changed" signal after
the window acknowledges the new size. To show a fancy resize animation,
gnome-shell creates a "screenshot" of the resizing window on the
"size-change" signal, and later animates that "screenshot" to the new
window size on the "size-changed" signal.
Now if a client is not responding to our requests asking it to change
its size, we get a "size-change" signal and start showing the
window-clone, but never a "size-changed" signal, animating and hiding
the clone again. This causes a so called "ghost window" that is shown
above everything else and never disappears again.
To fix that, start showing the window clone once we get the
"size-changed" signal instead of the "size-change" signal. This makes
sure the window actually updates its size and the clone is going to be
hidden again.

Creating a new GTimeZone for the local timezone can be quite expensive if
done repeatedly. It requires an open(), mmap(), and parsing of
/etc/localtime.
This patch was provided by Florian, and I've tested it as far back as
3.28.4 to ensure that we are really reducing the number of open() calls
on the compositor thread.

The g_file_replace_contents_async() API can potentially call fsync() from
the thread calling into it upon completion. This can have disasterous
effects when run from the compositor main thread such as complete stalls.
This is a followup to 86a00b6872 which
assumed (like the rest of us) that the fsync() would be performed on the
thread that was doing the I/O operations.
You can verify this with an strace -e fsync and cause terminal to display
a command completed notification (eg: from a backdrop window).
This also fixes a lifecycle bug for the variant, as
g_file_replace_contents_async() does not copy the data during the operation
as that is the responsibility of the caller. Instead, we just use a GBytes
variant and reference the variant there.

Sadly, xgettext's dealing with template strings is abysimal, so we
had to stop using them in files with translatable strings.
Make sure we don't accidentally sneak in template strings again(*)
and enforce that rule in a CI job.
(*) easy "mistake", considering how much nicer they are than
String.prototype.format()

Also known as "Piotr Drąg Bot".
We will soon make sure that files processed by xgettext don't use template
strings. To make that check as adequate as possible, ensure that no source
code files are missing from POTFILES.

The thumbnails actor `this._thumbnails` has already been destroyed when
calling `_destroyThumbnails()` from the `destroy` signal handler because
it is a child actor of the AppSwitcherPopup. So stop destroying the
thumbnails separately (fading them out inside a destroy handler wouldn't
make sense anyway).

The correct property for the scroll-direction with scrolling events is
`direction`, no `scroll_direction`. This fixes scrolling in the alt-tab
popup, which broke with the actorization changes.

When the switcherPopup was initiated successfully, we return true,
otherwise the WindowManager will try to destroy it. Since an early
release of the keystroke will also switch to another application and
close the switcher just fine, we should return true to indicate success
here.

Right now the index that gets selected on click and motion events is set
when connecting the event inside the addItem function. If items are
added or removed (for example when an application is closed by pressing
"q"), this index isn't valid anymore and has to be updated.
To fix this, use the items themselves instead of the index as arguments
for the event handlers and lookup the index of the item inside the event
handler.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/167
Set the accessible states of the switcherList items by calling a
function instead of manipulating class-internal variables from outside
the class, which is considered bad practice.
The check whether the item at `_selectedIndex` exists can also be
removed since we always select a new index after an item was removed
(i.e. an app was closed) and destroy the alt-tab switcher right away if
no more items exist (see `SwitcherPopup._itemRemovedHandler`).

Limit the minimum and maximum value to scroll to inside the box to 0 and
the upper limit, for some reason this was done right in _scrollToRight,
but not in _scrollToLeft.
This fixes the behavior of scrolling to the left: Before, scrolling one
item to the left moved the view to the first element of the list (this
can make the selected element invisible in large lists). Instead, scroll
one item to the left, just like scrolling to the right works.

Make sure the index that's being scrolled to doesn't change while the
scrolling animation is running by using an argument instead of the
this._highlighed class scope variable.
This fixes wrongly shown arrows when selecting new elements faster than
the scrolling animation takes for one index. The check run to disable
the arrow might be checking against a newer index than the one at the
start of the animation which results in the arrow not getting hidden
even if no more scrolling is possible.

Since this._highlighted is always set to the currently highlighted
index, there's no need to save the index to a separate variable. This
obviously depends on getting the new item highlighted as a result of the
item-entered event.
This fixes bugs in situations where the highlighted element changes
after an event that is not calling _onItemEnter, for example after
scrolling or pressing a key. In those cases the _currentItemEntered
variable wouldn't be updated and the old item couldn't be entered
anymore without entering another one before.

Visually the button is just an interactive label, so having the
interactive area extend to the empty space next to the label
is surprising.
Instead, left-align the whole button rather than just the label
inside, so the clickable area corresponds to the visible one.

The 'gdm' user is not going to run a media player, so there is no
point in allowing the corresponding section on the login screen.
All other sections are already disabled, so this is the only reason why
we end up with the message list instead of only showing the calendar.

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.

While the old merge request URLs still work, gitlab recently started

Adjust the regex to account for that, so that simply copying the URL

If the sessionMode does not allow to show the overview, we should also
hide an already visible overview.
This fixes a bug where, if the lockscreen was shown while the overview
was visible, the Ctrl+Alt+Tab popup would allow navigating inside the
overview because the overview actor is still mapped.

If a transition is reversed, the final property values will be the
same as before the transition. However this currently only works
correctly when we actually use a transition; to fix this with a
duration of 0, simply skip the set() call when the transition is
reversed.

Commit 6c6c89c634 added a pill around the default avatar, but
assumed the sizes from the vertical widget used on the lock screen.
In order to fix the horizontal widget on the login screen, move the
size-specific bits to the corresponding .horizontal and .vertical
sections, and half the sizes for the former (which corelates with
the icon sizes).

Implement ClutterActorClass.has_accessible() to ensure that CallyActor does not
recreate accessibles during the removal/destruction of an actor. This relies
on GNOME/mutter!1083 for the ClutterActorClass.has_accessible virtual function.
Running GNOME Shell for about 30 seconds results in a difference between
the two runs.
Before:
ALLOCATED TOTAL FUNCTION
[ 52.2 KiB] [ 0.05%] cally_actor_real_remove_actor
[ 36.3 KiB] [ 0.04%] st_widget_get_accessible
[ 9.8 KiB] [ 0.01%] atk_gobject_accessible_for_object
[ 3.2 KiB] [ 0.00%] g_signal_emit_by_name
[ 2.9 KiB] [ 0.00%] clutter_actor_get_children
After:
ALLOCATED TOTAL FUNCTION
[ 1.8 KiB] [ 0.00%] cally_actor_real_remove_actor
[ 1.1 KiB] [ 0.00%] clutter_actor_get_children
[ 659 bytes] [ 0.00%] g_signal_emit_by_name
Obviously 50KiB isn't a huge savings.
Although fixing things to avoid re-entrancy on destruction can be very useful
from a correctness standpoint.

We turned both the auth prompt's cancel button and the switch user
button into icon buttons now, which means they are completely cryptic
when using a screen reader.
Just use the previously used labels as accessible names, which has the
nice side effect of lowering the impact of the string freeze break.

The button is hidden on the lock screen, so it shouldn't be allowed to
activate it, be it via click or keyboard. The latter is still possible
by keynaving to the button and hitting space/enter. Fix that by making
the button unfocusable when we make it unreactive.

ShellStack implements custom focus navigation, and will only ever
navigate into its top-most child. That kind of makes sense as long
as that child is actually visible, but not when it is hidden.
Descend into the stack to look for a focusable child instead.

Since commit mutter/a2a8f0cda we force the focus surface of the
meta-wayland-pointer to NULL while the pointer is hidden. This
introduced an issue with the magnifier, where we use
`set_pointer_visible` to hide the real cursor and show our own cursor at
the correct position: Because the meta-wayland-pointer is still used to
communicate with Wayland clients, the UI of the windows will not respond
to mouse movement anymore as soon as the real cursor is hidden.
To fix this, use the newly added clutter_seat_inhibit_unfocus() API to
temporarily disable unsetting the focus-surface while the magnifier is
hiding the system cursor.
