This fixes a regression found in TestSceneQPainter for restarting the
Compositor. The internal clients were never added to the Scene.
We cannot just call setupCompositing because there is a phase during
startup where setupCompositing already passes but the Compositor is not
yet fully initialized. Thus it could happen that it's called twice which
makes the Scene assert.
To solve that setupCompositing and finishCompositing are now overriden
in ShellClient and track whether they successfully called
setupCompositing.
Summary:
We need to call Workspace::clientHidden when minimizing. Otherwise
Workspace doesn't update the active client and the now minimized
window is still active.
BUG: 366634
Test Plan:
Test case works now and also tested in nested setup that
active window changes.

With this change KWin can create window decorations for internal windows.
Thus it's also possible to move internal windows and resize them which is
especially important for the debug console.

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.
Test Plan:
Unfortunately no test case as this depends on phase-of-moon
aligning of destruction of the interfaces

Summary:
The idea is to not send multiple resize requests to a client when we
know that we might have multiple geometry changes. E.g. when going
from maximized to restored the borders change and trigger a resize in
addition to the resize from switching to restored.
The implementation is inspired by the GeometryUpdateBlocker.

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:
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.

Summary:
Preparation for also supporting XdgShell. There will be different
ctors for ShellSurface and XdgShell, but most code needs to be shared.
Thus a dedicated init method is needed.
There is some restructuring in the init. All code depending on
ShellSurface being set is grouped and in an if block.

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 introduces Toplevel::isLockScreen() and Toplevel::isInputMethod(),
this can be used to allow only lockscreen/inputmethods to get input
events and shown when screen is locked.
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.
Implementation goes to AbstractClient, method is no longer virtual.
The X11 specific code is moved to a new virtual protected doMove
method implemented in Client.
In Client existing method is marked as override, in ShellClient a new
override is added which delegates to requestGeometry. Existing method
is renamed to doSetGeometry and all internal calls delegat to it.
Needs better merging with the implementation of Client.
The changeMaximize method is added as a pure virtual protected method
to AbstractClient. This replaces the previous pure virtual maximize
method. Which is now directly implemented in AbstractClient (reusing
the implementation previously in Client).
So far we delegated to ShellSurfaceInterface, but it's possible that
we call into isFullscreen when the ShellSurfaceInterface is already
destroyed.
Note: the functionality needs to be slightly reworked. The fullscreen
state should change once we get a buffer for fullscreen, not when the
client requests it. This is a general pattern which is wrong also for
maximized, etc.
Merges together the code from ShellClient and Client and removes the
starting differences. Long term it's better to have only one
implementation to prevent diversions in the implementation.
As it doesn't match exactly protected virtual methods are called
which allow more specific implementations for a certain aspect of the
layer resolving.
A transient ShellClient has an offset position to the parent surface.
Use this to position the ShellClient properly.
This fixes the random placement of menus.
This change introduces a mechanism for internal windows to be rendered
to a QOpenGLFramebufferObject to be composited using the texture bound
to the FBO. This is useful for in-process rendering (e.g. QtQuick) and
at the same time bypassing the windowing system.
The OpenGL context of the QOpenGLFramebufferObject needs to be sharing
with the compositing OpenGL context.
The creation of PlasmaWindowInterface is moved from WaylandServer into
AbstractClient. This allows the sub classes to better control when to
create/destroy the Client.
For creation it's bound to becoming visible - that is Windows which are
only created but never shown are not announced at all.
For Client it's destroyed with the normal tear-down of a Client, for
ShellClient it's destroyed on unmapped (which also means a new one
will be created again in case of another mapping of the surface).
As a side effect, this works around the problem that ShellClients do not
yet get destroyed for QtWayland's menus (needs further investigation).
Prime target is to preserve the in-screen
condition of client AND window.i[1]
Atm. when the client is fully in sight
(but the window is not) - regardless of snapping
or screen change - a workspace update (screen change,
resolution change, adding/removing a strutting panel)
would allow the client to partiall escape screen bounds.
This is changed so that if the client is fully in sight,
it's kept fully in sight (but not the decoration)
If the entire window was fully in sight, it's also kept
(as is right now)
The code handles inner screen edges (if the client was in sight,
the entire window will be if we'd bleed to the other screen)
[1] I'd say that handling the client is more relevant,
but foresee more complaints if the window wasn't handled anymore ;-)
During that, i stumbled across some other issues.
- when a window centered on one screen is moved to a screen smaller
than the window, the window is shrinked to the dimensions of that
screen and now randomly touches eg. left AND right edge. When
moved back, the right and bottom edge were preferred
(to the window was "moved" into the lower right corner).
It's now kept centered.
- geom_restore was saved before keeping the window in the new
screen area (causing accidental drops on screen changes)

The PlasmaShell interface allows to create a PlasmaShellSurface for a
given Surface. Through this interface the Surface can request:
* a specific position
* a window type
So far only the window types Normal, Panel and Desktop are supported
which is a sufficient subset for getting plasmashell to work.
In future there should be security checks so that only the dedicated
desktop shell can bind these interfaces.
