Summary:
Plasmashell's desktop windows are RGBA which forces the compositor to
perform blending and render the background. That is absolutely pointless
as there is no window behind the desktop window it could blend to. All it
does is destroying KWin's more optimized code path and forcing additional
rendering which will never be visible (including shader push/pop).
With this change KWin forces desktop windows (both X11 and Wayland) to
be considered as opaque by setting the depth to 24. Thus blending is
disabled and the background is not rendered.
Test Plan:
Verified with apitrace that KWin goes in the opaque rendering
path for desktop windows.

ShellClient::doSetActive calls into focusToNull to deactivate active
windows on X11. But this should only be done when activating a
ShellClient. When deactivating a ShellClient the focusToNull can
result in an activated X-client to lose activation.
Thus this change ensures that focusToNull is only performed for a
now active ShellClient.

Summary:
Rational: unredirect fullscreen windows is a weird beast. It's intended
to make fullscreen windows "faster" by not compositing that screen. But
that doesn't really work as KWin jumps out of that condition pretty
quickly. E.g. whenever a tooltip window is shown. KWin itself has a
better functionality by supporting to block compositing completely.
The complete code was full of hacks around it to try to ensure that
things don't break.
Overall unredirect fullscreen has always been the odd one. We had it
because a compositor needs to have it, but it never got truly integrated.
E.g. effects don't interact with it properly so that some things randomly
work, others don't. Will it trigger the screenedge, probably yes, but
will it show the highlight: properly no.
By removing the functionality we finally acknowledge that this mode is
not maintained and has not been maintained for years and that we do not
intend to support it better in future. Over the years we tried to make
it more and more hidden: it's disabled for Intel GPUs, because it used
to crash KWin. It's marked as an "expert" option, etc.
It's clearly something we tried to hide from the user that it exists.
For Wayland the whole unredirect infrastructure doesn't make sense
either. There is no such thing as "unredirecting". We might make use
of passing buffers directly to the underlying stack, but that will be
done automatically when we know it can be done, not by some magic is
this a window of specific size.
Test Plan:
Compiles, cannot really test as I am an Intel user who never
had that working.

Summary:
The WaylandServer creates the XdgShellV5 interface and hooks it up
to create a ShellSurface whenever an xdg surface or xdg popup is created.
ShellClient gains some new ctors for the different variants and is
adjusted to delegate to xdg surface respectively.
With this change KWin mostly supports xdg-shell protocol. Still missing
is support for the "geometry" request which is rather difficult to
implement in KWin.

Summary:
So far when a ShellClient got unmapped ready_for_painting was set to
false. That is the ShellClient was treated in the same way as a not
yet shown window. It was completely excluded from painting, a close
animation impossible.
This change makes use of the functionality available in
Client::hiddenInternal(). The window is considered as hidden, thus
still excluded from e.g. getting input events, but could be rendered
any time as we still have a previous window pixmap (if referenced).
This allows to have it considered in the rendering pass, but effects
still cannot make use of it as that state is not yet exposed to the
effects.

Summary:
If the ShellSurface gets destroyed while a decoration repaint is pending,
it is possible that on tear down the decoration calls into
ShellClient::caption. This used to call into ShellSurfaceInterface::title
which accesses a d-ptr which is already destroyed at that point.
This change caches the caption instead of delegating to ShellSurface,
just like almost everything else caches. Thus the tear down cannot access
invalid memory.
Once we can depend on Frameworks 5.24, we should also make sure to
connect to the new Resource::unbound signal to be able to handle tear
down prior to the object being completely deleted.

Summary:
When managing a new decorated ShellClient we observed that the window
gets placed with a wrong geometry and on next damage event expands into
a strutted area.
The main reason for this behavior is that the window geometry did not
get updated when creating the decoration. With this change the geometry
gets updated, so that the placement is performed on the correct geometry.
The change itself does not yet cover all conditions. E.g. a maximized
windows which will get decorations will be incorrectly sized. This
requires further changes.

Summary:
For some windows we don't want to create a PlasmaWindow. Not all
ShellClients are something the outside world should see. This change
introduces the first restrictions:
* KWin internal windows are hidden
* transients not accepting focus are hidden
The latter case doesn't work though if the Surface is mapped prior
to creating the shell surface. In such a situation it's racy as KWin
handles the create surface request before we get the setTransient
request. This is difficult to handle as we do want to react quickly.

Summary:
The idea is to have KWin provide a virtual keyboard. To support this
KWin uses the QT_IM_MODULE qtvirtualkeyboard and makes sure that the
QPA plugin loads it.
KWin has a new class VirtualKeyboard which acts as the focus object and
the "proxy" for input methods. The QPA plugin ensures that this is the
focusObject, so that all input method related events are sent to this
class. From there it will be possible to delegate to other applications
through the Wayland interfaces.

Summary:
Most likely the window is in the process of getting destroyed. In that
case the following destroy of the Surface is also going to destroy the
decoration.
This was causing an interesting effect with the QQuickRenderControl used
by Aurorae. When getting destroyed it ensures that all posted events get
processed. This includes the destroy of the Surface which entered
ShellClient::destroyClient which again destroyed the decoration. In other
words a recursive destroy which ended with wonderful crashers due to
double deletions.
If the window is not unmapped this might still cause problems: more
testing needed.

Summary:
Toplevel::window() is the actual X11 window. This makes it difficult
to use as the generic identifier for both X11 and Wayland. The Wayland
ShellClient already had a windowId() which is now added to Toplevel as
a virtual method. On X11 (Toplevel default) it returns the window().
The method window() now returns XCB_WINDOW_NONE for classes without
the Toplevel::m_client, such as ShellClient. Thus it allows to properly
check whether we are on Wayland or X11.
The code is adjusted to use windowId where a generic id is needed and
to properly check whether the window is valid before using it where
a window() is used.
This also fixes at least one additional unknown issue in
Workspace::setActiveClient
where the windowId of a Wayland client was passed to X11.

The damage event of the Surface does not consider the offset through
the server side decoration. Due to that we need to have a different
repaint and damage area. As Toplevel::addDamage(QRegion) is only used
in the Wayland case the repaint adjustment is removed from the generic
implementation and moved into the specific implementations. While it
wouldn't hurt to have the repaint adjustment in Toplevel, it would
trigger a repaint of an unchanged area.
For Client I'm not sure whether it's correct without considering the
clientPos. My testing shows it's working, but that might also just be
do to Xwayland using OpenGL buffers. Needs further testing.
This is a complementary commit to 4c7450a1f6c314fe71768b95067ae5d48cc73811:
After Workspace gets destroyed it's possible that ShellClient's are still
around. Their tear down should not crash due to calling into Workspace.
If a ShellClient supports the ServerSideDecoration interface we can
create a server decoration for it. For that updateDecoration is added
as a pure virtual method in AbstractClient and a more-or-less code copy
from Client is added to ShellClient.
Geometry handling is adjusted to consider the window decoration offsets.
We announce support for it and depending on whether we have a plugin
or not set the default mode to Server or None.
When a decoration interface is created it gets installed on the
ShellClient. But there it isn't properly used yet as we don't have
support for decorations in ShellClient yet.
This describes an additional offset for the client content. On X11
our client content position matches with the window - the window
decoration is part of the overall content coordinate system.
On Wayland the content is an own texture starting at 0/0. Thus a
mapping to texture coordinates will be required when server side
decorations are provided. The new information is used in the scene's
to adjust the rendering and generating of quads.
Replacement for calls to info->input() which is only valid for the Client
sub class, but not for ShellClient.
In ShellClient the implementation is swapped with wantsInput() and
wantsInput() has a new implementation which properly delegates to rules()
just like Client does.
This allows to check if specific ShellClient is from LockScreen or not,
as well as this adds method to verify if ShellClient is from input
method like maliit.
Now that KWin knows about which window is from Screenlocker it can apply
various security restrictions like no other window then greeter is on
top of it.

Similar to X11 world: we send a sync request on each size change and
block till we get the next damage with the proper size.
Testing seems to show a very smooth resize experience. We automatically
sync to the resize speed of the client.
Maybe we need a timeout in case the client isn't able to resize to the
requested size.
