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.

Summary:
It was possible that we performed an early exit when the caption changes
and this results in the visible name being wrong. E.g if we have two
windows called foo, the second one has the visible name "foo <2>". After
changing that to "bar" the bug resulted in it still being the foo
variant instead of getting cleared.

Only needed for kwin_x11 variant (required for the non-composited
Outline). As that's nowadays in the x11 platform, we can move the
complete XRenderUtils support into the platform. Thus KWin core does
no longer require to link it.

Summary:
After changing the output configuration, the client expects that it is informed
whether or not a new configuration has been applied (or failed). This was ommitted
so far, meaning that clients wouldn't know what happened in kwin.
Since we don't track if a setting failed yet, send the applied() signal regardless.

Summary:
This is needed in virtual keyboard and also used KKeyServer so far. With
this change it is moved to new API provided in Xkb. The new translation
map is now also used for the direction from Qt::Key +
Qt::KeyboardModifier to xkb_keysym_t.
New implementation is supported by a new test case covering the same
combinations as in the existing direction.

Summary:
Libinput returns -1 when calling libinput_event_touch_get_slot on an event
from a single-touch touchscreen. The returned value is used in
DecorationEventFilter to determine the touch which is acting on it. The value -1
is used to signify that the decoration is not being acted on. Thus when
releasing the touch, it checks whether it was being dragged, and as it thinks
it isn't, it doesn't handle it and the decoration is still being dragged.
Clicking on the decoration then crashes kwin.
Test Plan: Move a window by dragging the decoration with a single-touch touchscreen.

In the DRM plugin the cursor is currently is drawn at the native size

Therefore we don't want to scale the icon offset as that leads to it

Summary:
This change introduces a dedicated X11EventFilter for the mouse
interception on X11. The filter gets created together with the start
of mouse interception and destroyed again when the mouse interception
ends. Thus we don't need to check for each event like it was the case
so far.
Unfortunately the existing methods cannot be removed (yet) as they are
still used by TabBox. Needs investigation whether this is actually
needed.

Summary:
Several effects announce a support property atom on the root window. This
change forwards the KWin::Application's signal that the xcbConnection
changed to the EffectsHandler so that the effects can respond to it.
All effects which announce a support property connect to this new signal
and re-announce the property. In case the xcb connection died (future
XWayland crashing case) it is set to XCB_ATOM_NONE by that. In case the
xcb connection got created (future delayed XWayland startup) the atom is
set to the proper value.
In addition all usages of the support properties are guarded, so that no
nonesense actions are performed if the support property is XCB_ATOM_NONE.

Summary:
The code in events.cpp was problematic as it was called in a Wayland
session. So KWin changed outputs, this gets mirrored to XWayland and
then KWin reacted on the XRandR event and might have even changed the
refresh rate due to that - bad idea.
This change moves the code into the already existing X11EventFilter for
XRandR events in XRandRScreens.
Test Plan: Run kwin_x11 in gdb on Xephyr, breakpoint in new code and triggered XRandR event

Summary:
We had a few places (e.g. DebugConsole, Platform) where the Scene was
cased into a SceneOpenGL to access the backend and get the extensions.
This change simplifies that by adding a virtual method to Scene directly
which is implemented in SceneOpenGL and returns the backend's
extensions.
Thus the casts to SceneOpenGL are no longer required.
Test Plan:
Opened debug console to verify extensions are listed,
triggered Outline to verify the sharing QPA context gets created.

Summary:
The RuleBook is created during Workspace startup, so it's a required
component for the overall KWin session. It uses a KXMessages object which
means it has a hard X11 runtime dependency.
This change makes the dependency optional and creates the KXMessages once
X11 is available.

Summary:
Several of the subclasses are already derived from QObject.
The main reason is that the class should be moved out of KWin core in
order to move the OpenGL scene into a plugin. As Compositor calls into
the AbstractEglBackend to unbind the wayland display this creates a
problem which is easily solved by turning the AbstractEglBackend into a
QObject and connect to the signal emitted by the Compositor.

Summary:
So far the Platform performed a deep query into the AbstractEglBackend
to get information such as EGLContext, EGLConfig, EGLSurface. This
change adjusts this so that the AbstractEGLPlatform forwards it directly
whenever it gets informed about one following the approach already used
for EGLDisplay. This simplifies the code a lot and allows to remove the
dependency on the actual scene backend from the Platform (in order to
split out the SceneOpenGL into a plugin).
Test Plan:
Run nested kwin_wayland, triggered Outline which requires all
those methods.

Summary:
TabBox implemented a custom way to check whether two windows belong to
the same application. KWin internally has API for that which does it
better, in a standardized way and even across windowing system.
This change uses the internal API, resulting in the check working better
on X11 and starts to work on Wayland.

Summary:
The syncing of the window geometry to the internal geometry can
unfortunately cause a freeze in very special conditions:
1. create QML component
2. a Plasma::Dialog gets created
3. It creates the DialogShadows
4. This triggers QGlobalStatic creation which locks a non-recursive
mutex
5. The creation of DialogShadows creates a Registry and triggers a
roundtrip on the Wayland server
6. KWin processes all Wayland events
7. This triggers the creation of a ShellClient
8. The ShellClient has a PlasmaShellSurface which requested a position
9. The new geometry does not match the geometry of the Plasma::Dialog
10. ShellClient syncs the geometry to the Plasma::Dialog
11. Plasma::Dialog updates the theme because window geometry changed
12. This accesses the DialogShadows...
which is still in the non recursive mutex and we have a freeze.
By delaying the sync to the end of cycle we jump out of this deadly
sequence.
BUG: 384441
Test Plan:
The freeze doesn't hit any more. It's possible that some test
cases need adjustments.
