Turns out that shell_screenshot_screenshot_area was affected
by the same issue that shell_screenshot_screenshot used to have.
Adapting code changes from commit id c09be8b0:
"screenshot: Grab screenshot during paint on X11" fixes it.

While most secrets are serialized as individual settings with a string
value, all VPN secrets are serialized together as a string dict which is
the value of a single setting. Incorrect serialization causes VPN
secrets to not be remembered by NetworkManager.
This commit adds a new method that allows adding secrets as VPN secrets
specifically such that they can be correctly serialized.

What the blur shader does is going n_steps in each direction (e.g. in case
we're in the horizontal pass that means left and right direction), sampling
the adjacent texels of the texel we're currently blurring. That means
n_steps actually is the amount of texels we're sampling in one direction,
not in both directions.
Make n_steps match what the blur shader does, and rename it to sampling_radius
to match what it really means. Do that for both st-theme-node-drawing.c and
st-private.c

This new ClutterOffscreenEffect vastly simplifies subclasses
by allowing them to hand the parent class a CoglPipeline to
use.
Override the create_pipeline() vfunc and return the (cached)
pipeline. Remove the paint_target() override and the now
unnecessary texture size fields from the structure.

We might not be able to directly paint the stage to an offscreen, if
there currently is a fullscreen unredirected window. To make it possible
to take a screenshot in this situation, disable unredirecting, queue a
frame, and take a screenshot after having painted that frame, before we
go back being unredirected.
Don't do this on Wayland because it's a waste.

With ClutterBlurNode available, we can remove our own implementation
and delegate the blur shader and framebuffers. This simply replaces
the pair of layer nodes (vblur and hblur) with a ClutterBlurNode,
and removes all dead code.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1528>
Port the blur effect to the new ClutterEffect.paint_node() vfunc.
Update the function names to match what they do, e.g. "apply_blur()"
now creates the blur subtree and thus was appropriately renamed to
"create_blur_nodes()".
There are 3 subtrees that can be generated by the blur effect:
1. Actor mode (full subtree; no cache)
Root
|
|
Layer (brightness)
|
Layer (horizontal blur)
|
Layer (vertical blur)
|
Layer (actor)
|
Transform (downscale)
|
Actor
2. Actor mode (partial subtree; cached contents)
Root
|
Pipeline
(final result)
3. Background mode
Root
|-----------------------
| |
Layer (brightness) Actor
|
Layer (horizontal blur)

Layer (vertical blur)

Screen magnification is the compositor's business, not that of "random"
unprivileged tools. And for cases where a more specialised behavior is
wanted, an extension likely does a better job than a consumer of the
D-Bus API.
In addition to that, exporting the interface has been broken for an
unknown time, because the object that holds the implementation isn't
referenced and thus ends up being garbage collected, whoops.
And last but not least, this gets rid of the last public D-Bus name
that isn't clearly in the system namespace (org.gnome.Shell,
org.gnome.Mutter, org.gtk).

This is a relict from the pre-3.0 days, when it was common to
replace a running GNOME 2 session with gnome-shell. There has
been no good reason to claim the name for many years, time to
drop it.
If someone really wants to run gnome-panel alongside the shell,
they probably know what they are doing. Or cannot be helped anyway.

In some styles the top or left sections of box-shadows would go missing
even though they had non-zero thickness. This was because the inner
local coordinates could become very slightly negative and were then
incorrectly judged to be invisible.
Negative coordinates should not be ignored because that's where the
entire top/left sections of shadow are meant to exist. It's only the
sections of shadow with zero thickness that we should skip.

Not checking for this would result in `clutter_actor_add_child`
failing, but StBin keeping a copy in `priv->child`. So later on,
`st_bin_remove` would never be called on it and this assertion
would fail and crash the whole shell:
```
static void
st_bin_destroy (ClutterActor *actor)
{
StBinPrivate *priv = st_bin_get_instance_private (ST_BIN (actor));
if (priv->child)
clutter_actor_destroy (priv->child);
g_assert (priv->child == NULL);
```
By disallowing spurious `st_bin_set_child` calls we now prevent StBin
from entering such a corrupt state and the above assertion won't fail
anymore.

Just like the internal ClutterText, the icon actors are part of the
entry. It therefore makes sense for the icons to not react to clicks
when the entry itself is non-reactive; again, just like the text.
That behavior is also consistent with icons in GTK entries.

Like `GtkAdjustment`, `StAdjustment:changed` is not emitted for the
`value` property except when changed with `st_adjustment_set_values()`.
Note this behaviour in the signal documentation

(optional) is only valid for (out) or (inout) parameters (that are
marked as such).
However GError** arguments appear as throws="1" in the GIR anyway
instead of an explicit parameter, so we don't need any annotation
at all here.

Much of St is undocumented, aside from input/output arguments. This is
no doubt because a lot of it parallels Gtk closely, but is worth
improving since many new programmers are not familiar with Gtk.

This eliminates the need to wait for redraws, drawing cursors, and
stiching together cairo images in case the screenshot covers multiple
monitors.
All of that is now handled by mutter itself.

The framebuffer we use for rendering shadows is scaled by the resource
scale, that means we also need to offset coordinates when translating
them to the framebuffers coordinate system.
So far we forgot to do that when translating the framebuffer using the
position of the actor, which lead to small rendering bugs of
text-shadows for actors allocated at non-zero origins. To fix that,
simply multiply those positions with the actors resource scale.

To do this, we now wait for the start/stop job to complete. We also have
two targets in gnome-session to ensure that everything is working as
expected.
In order to start the services, we simply request the
gnome-session-x11-services-ready.target unit, and wait for it to become
available. To stop, we use the gnome-session-x11-services.target unit
which should stop all services in a way that is entirely race free.
This requires both gnome-session and gnome-settings-daemon changes to
work (which are in the corresponding merge requests).

Move the screencasting into a separate D-Bus service process, using
PipeWire instead of Clutter API. The service is implemented in
Javascript using the dbusService.js helper, and implements the same API
as was done by screencast.js and the corresponding C code.

The timeout seems to have been carried over from the old code that
relied on gnome-shell calling 'GetEvents' after every 'Changed' signal
where it was used to throttle the signal. In the new code where
calendar-server is sending the changes themselves via signals this is no
longer necessary and actually causes a delay when switching between
months.

When using the NVIDIA driver, textures tend to loose their pixels when
suspending. In the past we handled this by figuring out when the NVIDIA
driver was used, and reload the background whenever we noticed we
resumed from suspend.
This shouldn't be needed anymore after
https://gitlab.gnome.org/GNOME/mutter/merge_requests/600, as it should
handle this by listening to video-memory-purged signal. Thus remove our
special handling here.

Since commit b60836932 we only allow WM_CLASS matches for sandboxed
applications if the found app's ID is prefixed by the sandbox ID.
The existing check still has a hole in it though: "org.example.Foo"
and "org.example.FooDevel" are different applications, yet the former
is a prefix of the latter.
So tighten the check by including a trailing "." in the checked prefix;
this excludes cases like the above, while still working for the regular
case of a single .desktop file because our app IDs include the ".desktop"
suffix.
Spotted by wjt.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1357
Currently our heuristics for matching a window to its app check
for the application ID before the WM_CLASS, as the ID is more
reliable in so far that it is outside the application's control
and so it cannot use it to spoof a different application.
However this also prevents applications with multiple .desktop
files like LibreOffice from matching any .desktop files other
than the one under the main ID.
Since we now no longer allow the WM_CLASS to match a .desktop
file that doesn't belong to the sandboxed application, we can
fix that issue by checking the WM_CLASS first, without opening
the door to spoofing.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/219
At least flatpak (no idea about snap, sorry) enforces that all .desktop
files exported by a sandboxed app use the application ID as prefix.
Add the same check when trying to find a match based on the WM_CLASS,
to prevent sandboxed apps from matching a .desktop file they do not
own.
At the moment this is unlikely as we check for a match on the
sandboxed app ID first, but we are about to change that.
