2a6306c498 shell: Use swapped signal connection for MetaWindowActor::destroy
The callback would schedule a clutter_actor_destroy() on the first
argument. Unless told otherwise, this is the same actor that is
already being destroyed, so this is a no-op.

Instead, the intent is to make the clone follow up destruction of
the window actor so that it results in correct removal of this
window from the ShellWindowPreviewLayout. Use a swapped connection
to pass the clone actor as the first argument of the signal callback.

9777594fe9 shell-app-system: Give priority to .desktop IDs that should be shown
If we have multiple desktop ID's that share the same startup-wm class
and none of them is actually matching the desktop-id, then we should
exclude the ones that should not be shown in the current desktop.

This will help preventing cases such as the previous one in case no
desktop file ID would match the startup-wm-class exactly.

bb64d077ef shell-app-system: Do not compare startup-wm classes with full desktop IDs
When fetching the desktop ids into a map of startup-wm classes we meant
to give the ones that match the desktop ID more priority, however
this did not happen because we were always comparing a desktop
file id, including the `.desktop` suffix, with a wm-class that generally
does not include that.

This is the case of gnome-system-monitor, that provides two desktop
files, one of which is OnlyShowIn=KDE but both have the same
StartupWMClass and thus the first parsed is preferred, even though its
desktop-id is gnome-system-monitor-kde.

As per this, remove the .desktop suffix when comparing it with the
startup-wm-class, keeping the old check just in case.

937594b806 window-tracker: Only emit ::tracked-windows-changed on title changes
Since commit a1d650ce27, window title changes are listened for in the
ShellWindowTracker in order to emit ::tracked-windows-changed when
there are window title changes.

The rest of the things that happen in between (removing the window
from a ShellApp, possibly have it destroyed, and possibly creating a
new ShellApp to re-insert the window) are superfluous and even result
in the altTab switcher popup ending up confused about the applications
available.

Only emit the signal so changes can be followed on D-Bus, but avoid
the ShellApp fiddling otherwise.

5db40c1ead window-tracker: Emit 'tracked-windows-changed' on title changes
This means the screen share window view gets updated also when the title
of a window changes. This is important since it often changes shortly
after mapping, which would otherwise go unnoticed by
xdg-desktop-portal-gnome.

An example is launching Files and it showing up as 'Loading..', or
launching a terminal, and it not showing the proper title (current
directory), but some place holder that is never visible on the
application window.

Adding it to the window tracker instead of in introspect.js itself is
for convenience - there is no per window signal tracking there, and it
already listens to the signal emissions about changed windows.

We currently don't update running apps when the set of installed

 - the app got uninstalled, and the running app should become
   window-backed

 - a newly installed app got launched before the app cache was
   updated, and we replace the window-backed fallback with the

Commit 9168f6055e marked the parameter as nullable, which is in

When saving a screenshot, the GdkPixbuf created would be left
with a dangling reference after saving to disk (either leaked
on errors, or via an extra reference on success). Always unref
the pixbuf so it's either destroyed on error or there is a single
reference fully transferred to the caller of the function.

83564e59b3 workspace: Port WorkspaceBackground allocate to C
WorkspaceBackground's allocate is a hot function called every frame
during overview animations. Port it to C.

While we're at it, cache the work area and the monitor geometry, which
do not need to be re-fetched on every allocation.

This reduces the average WorkspaceBackground allocation time from
0.134 ms to 0.017 ms. With four workspaces, scrolling the overview sees
an average WorkspacesView allocation time improvement from
1.104 ms to 0.678 ms.

1bd9076590 main: Define a custom log writer to dump on structured messages
Even though GNOME Shell is not explicitly using structured logging via
G_LOG_USE_STRUCTURED, GLib uses it as default since 2016 [1], and so
we're de facto using it.

As per this, if backtrace on warnings is enabled, it is ignored since the
log handler isn't used anymore, and no dump is printed.

Thus, replace the default log handlers with writer functions instead, honoring
backtrace-warnings debug string.

918c063693 st: Generate shadows from the silhouette of the source texture
As first mentioned in commit 672171093, the CSS spec defines shadow
colors independently from the colors casting the shadow. It's not
a physical light simulation so a shadow is allowed to be a different
color from texture casting it.

This means we only care about the shape of the source where alpha
values of zero are adjacent to alpha values of non-zero. And all such
non-zero pixels should be treated as fully opaque for the purpose of
shadow generation. While this would be wrong for a physical light
simulation it does allow us to cast shadows around semi-translucent
shapes and better support CSS.

The fade effect can also be added to the scroll view programatically
instead of using CSS via the st_scroll_view_update_fade_effect() API.

We make use of this API in the appDisplay, but since commit ba547ec1d
the fade margins get overridden to 0.0 from the ::style-changed handler.
Fix this by only setting the fade margins when CSS actually defines a
custom vfade/hfade offset.

8b3e1e01f6 st/label: Invalidate text shadow on style changes to ClutterText
Just like with the last commit, listen to some ClutterText property
changes to catch style changes that were trigerred by
_st_set_text_from_style() and invalidate the shadow spec on changes.

898334f31d st/entry: Invalidate text shadow on style changes to ClutterText
We update a few properties of ClutterText when the CSS changes via
_st_set_text_from_style() (which we call when receiving the
style-changed signal).

Right now we simply invalidate the text shadow every time we receive the
style-changed signal, but we're going to change that with the next
commits. To ensure the shadow still gets invalidated on CSS changed that
might affect the shadow, listen to a bunch of property changes that will
get notified when any property that affects the shadow changes.

2bb36db9e8 st/entry: Invalidate shadow on cursor position/size changes
When text shadows are used, the cursor indicating the current position
also casts a shadow.

This means we have to regenerate the shadow texture after the cursor
position changed, so invalidate the shadow in that case.

57d681863a shell: Shuffle ifdef to fix !HAVE_SYSTEMD build
The internal SystemdFlags enum is used from common code for
both systemd availability cases. Shuffle it outside the ifdef
so it's seen everywhere.
