So far if the Scene creation failed kwin_wayland went into a shutdown,
but didn't succeed because the thread to start Xwayland was already
running: it froze.
This change introduces a new signal in Compositor: sceneCreated. The
startup of Xwayland is bound to this signal. If it gets fired KWin can
startup Xwayland. If it does not get fired, KWin terminates correctly.
Summary:
If a window has an invalid size the decoration also has an invalid
size. This results in the texture used by the
SceneOpenGLDecorationRenderer to be invalid and being reset to null.
Of course we shouldn't try to use this texture to render to.
The change comes with a test case to simulate the situation. We cannot
simulate it with Wayland clients as the geometry can never be empty.
Thus we create an X11 client, resize it to an empty size and unmap it.
This is the first integration test case which creates an X11 Client!
It's also a test case which needs the OpenGL compositor. This will most
likely not work on build.kde.org yet - we need to see what to do about
it. Will need adjustments to get it at least skip on build.kde.org.

Summary:
Mostly meant for multi-screen setups: we don't want that a strut set on
a window on screen 0 results in screen 1 completely being excluded. Even
if that's strictly seen a client bug, it's better to just ignore the
strut from KWin's side.
The sanity check is implemented in Client::adjustedClientArea.
From a pure standard point of view this change is a EWMH violation and
thus can cause regressions: struts by clients no longer working.
A test case for struts is added, including some invalid combinations
whose strut is ignored with this change.

Summary:
KWin needs the plugin id of the breeze decoration plugin. Instead
of hard coding that it's now resolved through an optional dependency.
If the optional dependency is not available, the default is adjusted
to aurorae/plastik.

By moving XRandrScreens the creation of screens gets simplified a lot
as there is no need to have windowing system specific init code. It all
just goes through the platform.
This also marks the point where the first X11 specific code is removed
from kwin_wayland.

kwin_x11 now also loads a platform plugin and initializes it.
It doesn't do much except loading it and init it. Though it's also
set up to continue startup only when screens are queried.
The plugin does not much. It's the most basic plugin we can have to
be loaded from kwin_x11.
Unlike the wayland platform plugins it gets installed to:
org.kde.kwin.platforms
Summary:
Source code reorganization:
The base class AbstractBackend got renamed to Platform, thus the
"backends" are "platforms" now. As they are plugins they should go
together with other KWin plugins which are nowadays in the folder
plugins.
So new location is plugins/platforms/

Summary:
It looks like something was forgotten here - there is
a completely empty body for an if statement that checks
whether the pointer is null.
So this might not be the desired way to fix this.
Should m_lastCreatedSettings be instantiated instead?

Summary:
From the rest of this method, it is obvious that m_topLevel can
be null in any part of the method - we are checking against it
being null in a few places in the method - both before and after
the affending lines.
Now, there is one place where the check is not applied, and
potentially calls ->window() on the null pointer.
p.s. If there are more places where kwin does clear_or_something(); return;
it could benefit from introducing on_scope_exit and similar tricks - see
Alexandrescu's 'Declarative control flow' presentation.

Summary:
This is the first change in a refactoring series. The aim is to:
* rename AbstractBackend to Platform
* move backends/ to plugins/platforms/
* don't bind platforms to Wayland only
* provide a platform plugin for "normal" X11
* share more code between X11 and Wayland
This change moves the platform/backend from waylandServer to Application.
The init of the plugin happens directly in the Application from the
KPluginMetaData. There is no need to externally init it and set the
parent.
WaylandServer::backend() currently just delegates to
kwinApp()->platform(), the idea is to drop this method completely.
The test infrastructure is also adjusted to this change.
Test Plan: kwin_wayland still works, all tests pass

This is more a hack than an actual implementation. It just renders
all sub-surfaces after the main window got rendered. But it does not:
* use window quads (e.g. splitting not supported)
* is not combined with rendering of the main surface
* does not support previous pixmap
Still it renders, which is the main goal at the moment.
The rendering is done in a recursive way. For updating the buffer an
important change is done: the buffer is copied into a new QImage on each
change and the differences are no longer painted. This is due to damage
region in a sub-surface tree being basically unknown.
This change introduces a tree for WindowPixmap. A WindowPixmap can
have a parent WindowPixmap and children. Each child represents a
SubSurface and references the buffer of that SubSurface.
The tree of WindowPixmaps is updated each time updateBuffer is called.
If there are new SubSurfaces new WindowPixmaps are created, for removed
SubSurfaces the old WindowPixmap gets removed. Also the ordering is
updated to reflect the current state.
This is currently rather expensive and should be changed to only rebuild
the tree if it actually changed.
Searching for "animation speed" now points to the Compositing KCM, where
the animation speed setting is, instead of the Destkop Effects KCM,
where it was before.
Same for compositing, OpenGL, XRender and video settings

On build.kde.org we cannot use the breeze cursor theme. Instead we have
DMZ-White (debian package dmz-cursor-theme).
This change adjusts the PointerInput test to enforce DMZ-White and uses
SizeAllCursor instead of OpenHandCursor as that one seems to be missing
in that theme.
Hopefully with these changes the test starts to pass on build.kde.org.
