Summary:
Currently, there is a guarantee that a client, which is about to be removed,
is no longer in the stacking order(both in constrained and unconstrained)
when Workspace::removeClient is called. However, because the client gets
removed from m_allClients after clientRemoved is emitted, it can be
re-inserted back into the stacking order.
In general, the pattern is to do some work and then notify others about
what you've done by emitting a signal. In the case of Workspace::removeClient,
we emit clientRemoved way before the client actually gets removed.

Test Plan:
* Enable the following script:
```lang=js
workspace.clientAdded.connect(function (client) {
if (client.skipTaskbar || client.modal || client.transient) {
return;
}
workspace.desktops = workspace.desktops + 1;
workspace.currentDesktop = workspace.desktops;
client.desktop = workspace.currentDesktop;
});
workspace.clientRemoved.connect(function (client) {
if (client.skipTaskbar || client.modal || client.transient) {
return;
}
workspace.desktops = workspace.desktops - 1;
});
```
* Open an app, close the app.

Summary:
implement virtual desktop support for Wayland.
use the new virtual desktop protocol from D12820
The VirtualDesktopManager class needed some big change in order
to accomodate it, which is where most changes are.
Other than that, it's mostly connections to wire up
VirtualDesktopsManager and VirtualDesktopsManagement(the wayland protocol impl)
Depends on D12820
Other notable detail, is the client visibility updated to reflect the presence
of the client in the plasmavirtualdesktop.
(and the unSetDesktop concept)
Test Plan: used a bit a plasma session together with D12820, D13748 and D13746

Summary:
The main reason for not having it as a mandatory dependency was that BSD
doesn't support it. But as I learned recently it is available on our CI
system. So BSDs have support now.
Even more it showed that the code doesn't compile if the dependency is
missing. And there's one thing I hate: broken build configuration
options.
So let's make UDEV and libinput a required dependency and get rid of the
problems.

Summary:
The xStackingOrder unlike indicated by it's name is relevant for both
X11 and Wayland and contains the stacking order of the windows used for
compositing.
So far it was determined whether it needs to be recreated based on
whether an xcb query is pending. This change introduces a boolean
variable to check whether the stacking order is dirty and guards the X11
specific code to only be run if we have an X11 connection.
This is to my current knowledge the last remaining issue where X11 was
used during the normal Wayland operation mode. Now it should be possible
to re-order the Workspace startup [1] and try to run kwin_wayland without
Wayland support.
[1] Workspace::Workspace and Workspace::init is still highly X11
specific and needs to be split into X11 only and general parts.

Summary:
The ObscurringWindows are a hack to make it more unlikely that the
desktop wallpaper becomes visible while switching desktops. This was
introduced in 2001 with SVN revision 90111
(git d194f74314).
In 2001 desktop switching was probably a costly action where it was not
possible to just reorder the desktop in one frame. Nowadays we use
mostly compositing and with compositing the ObscurringWindows are
already disabled. But even in the case that no compositing is used I
consider it as very unlikely that the desktop becomes visible during the
switching. Given that I think it's time to remove this legacy solution.

Seems to have been used in old compositing kcm, documented as DBus API.
But Workspace doesn't expose a DBus interface anymore and our new DBus
interface does not call this method -> it is dead.
Summary:
The code ifdefed by ENABLE_TRANSIENCY_CHECK does no longer compile and
has not compiled since the switch to Qt 5 and KF5 as it still uses
kDebug and (worse) kDBacktrace. There are several other changes which
broke the code and I failed trying to get it to compile again. It's a
classic example of bitrot happening to code which is never getting
compiled.
As this has not been in a state which could compile for at least several
years, I think it's best to completely remove it.

Workspace monitors the X11 events to detect when the user first

dedicated event filter is introduced which also gets deleted again once

This change addresses the problem and adds a test case which triggered

it took me about an hour to write the test for the crash.

Introduce a method Workspace::markXStackingOrderAsDirty
Summary:
This method replaces the calls x_stacking_dirty = true in the code base
allowing for further refactoring of that functionality.
Remove roundtrip to XServer from Workspace::xStackingOrder
The method xStackingOrder is only used during a Compositor paint pass.
If the stacking order had changed, the method updated the stacking order
from X by performing a sync XQueryTree. With other words we had a round
trip to the X server directly in the paint pass.
This change rearchitectures this area by making better use of xcb. When
we notice that the stacking order changed and an XQueryTree is needed,
we directly send out the request. When xStackingOrder is finally called,
which normally happens a few milliseconds later, the reply is retreived.
In the worst case it still blocks, but in most cases the roundtrip is
gone.
If the stacking order changed again before accessing xStackingOrder the
running request is cancelled and a new request is issued. So whenever we
get into xStackingOrder it will have the current state.
The updating of the xStackingOrder is moved into a dedicated method and
xStackingOrder invokes it through a const_cast instead of operating on
mutable variables.

Summary:
KWin always has a few internal windows around which are not visible.
A QWindow created somewhere, but not shown. Such windows should not
be part of the stacking order.
If they are it breaks code which looks at the top most window in the

This change ensures that the stacking order gets updated whenever a
ShellClient gets hidden and that internal windows with isShown being
false are excluded from the stacking order.

The restore geometry gets initially set to 0/0xsize before the placement
is done. When going into updateClientArea and then afterwards into
AbstractClient::checkWorkspacePosition the geometry restory is used for
calculating the new position. This results in windows getting moved to
0/0 when e.g. plugging in a new screen or a panel changes, etc.
This change ensures that the restore geometry is set correctly after the
first placement.

This allows finding the Toplevel for a QWindow which is on Wayland a
ShellClient and on X11 an Unmanaged. This can be used to simplify
code when a Toplevel is needed for an internal QWindow without having
to do platform specific checks.
For the exit-with-session option in kwin_wayland there is a chance that
the window which triggered termination is currently a Deleted. The
Wayland shutdown sequence terminates Workspace before the Compositor
which results in that Deleted's Scene::Window surviving the shutdown
process and thus the Shadow not being removed from the cache. This
makes KWin assert very late in the shutdown process when the decoration
shadow cache gets destroyed.
Summary:
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:
When a ShellClient gets unmapped and mapped again the signal windowShown
gets emitted. We need to handle this in Workspace to ensure the window
is in the proper layer and gets focus.
This fixes applications like KRunner/Yakuake not having focus on a
second show. Unfortunately it also brings back the problem that
notifiations steal focus (this needs to be fixed by passing a proper
window type to a notification).

Summary:
The method xRenderBlendPicture created a static XRenderPicture on
first usage. To cleanup a XRenderPicture an xcb_connection_t* is needed.
As it's static the cleanup happens on exit handler and at that time Qt
already destroyed the xcb_connection_t*. With a certain chance this will
crash.
To expose the problem a Q_ASSERT(qApp) is added in the destructor of
XRenderPicture. Using xrenderBlendPicture() will hit this assert on
application exit. This is demonstrated by the added auto test.
The actual fix to the problem is moving the static variable out of
the method and introduce a global cleanup method just like the init
method. This is now called from Workspace dtor, so before application
goes down.

Summary:
Client uses a static Xcb::Window helper. This so far didn't get
explicitly destroyed, so the application finalize cleaned it up.
To destroy the window the xcb_connection_t* is used which the
QGuiApplication already destroyed.
This change ensures that the window gets destroyed before the xcb
connection gets destroyed.
In addition an assert is added to KWin::connection() to ensure that
we still have the QGuiApplication::instance() when it's invoked.
This way we'll notice if we have more cases where we call into xcb
after the application went down.
