Both Wayland and X11 backend are bound to the --windowed flag. Which
one to create is decided whether DISPLAY or WAYLAND_DISPLAY env variables
are set with Wayland having precedence over X11. Passing the display as
command line argument overwrites the env variable and takes further
precedence. E.g. if WAYLAND_DISPLAY is exported and --x11-display
argument is provided, it will create X11 backend. Similarly there is now
a --wayland-display command line argument.
If no backend got created, kwin_wayland will exit.
The singleton variant of WaylandBackend is adjusted to take the display
as argument and pass it to the Connection.
When a sync object is deleted, the fence it is connected to must already
be signalled, or the driver will busy-wait forever.
Signal fences before deleting syncs to avoid this.

The closeview is not hidden because that causes
invalid textures (apparently QML related) and
deleting/recreating causes massive I/O overhead
on effect invocation.
As last resort, the window is "hidden" by moving
it out of the root window geometry.
Jonathan, please RESPIN kwin - sorry for the trouble
... again.

The AbstractBackend registers itself in the WaylandServer allowing
external users to easily get to the backend and not needing to test
manually which backend is used.
There's quite some overlap and duplicated code. This AbstractEglBackend
tries to merge the two backends a little bit again.
This also introduces an AbstractEglTexture which supports both X11 and
Wayland "pixmaps" so that EglOnXBackend can support Wayland buffers.
Mostly refactoring to not take the global X11 information (connection,
display, etc.). Adds a dedicated ctor overload which takes the
X11WindowedBackend.
SceneOpenGL is adjusted to create an EGLOnXBackend instead of Wayland one
if the X11WindowedBackend is used.
Adds optional dependency to X11_XCB and gets used in X11WindowedBackend
to create an XLib Display if dependency is present.
This allows to create an EGL backend for the X11WindowedBackend.
This new backend allows to start a kwin_wayland server nested on an
X-Server by using a normal X11 window as output. This allows testing
kwin_wayland without needing to start another Wayland server first.
The behavior is triggered by using new command line arguments:
--windowed
--x11-display=<:0>
With optional --width and --height arguments.
In this mode the WaylandBackend is not created at all.
So far the backend is not fully integrated yet and only the QPainter
backend supports this mode.
The xcb_cursor_t returned by xcb-cursor library might be broken. If we
set such a broken cursor directly in the create window call it will fail
with a BadCursor value causing effects to break.
This change works around this problem by creating just the window and
moving the possible breaking call into a change window call. That will
still fail, but the window is working.
In addition it performs a safety check by only installing the cursor
if it's not XCB_CURSOR_NONE.

This requires a change present in Qt 5.4.2, without the startup will
freeze. A warning message is shown if the compiled Qt version is not
at least 5.4.2. It's only a warning and an ifdef as distros might
backport the required change.
This replaces getting the Cursor through the X11CursorTracker which
is now completely dropped. The Cursor data is now passed through from
the Wayland server and forwared to the WaylandBackend.
Pointer events are no longer sent through the methods on Toplevel,
but properly sent through the SeatInterface. This has the advantage
that SeatInterface properly tracks which is the focused pointer surface
and does not need to use the xtest extension.
WaylandServer allows to create a ClientConnection which is intended for
QtWayland. This allows us to easily identify our "own" surfaces. The
created file descriptor is set as env variable WAYLAND_SOCKET prior to
creating the Application. Wayland will unset it after connecting, so we
don't need to unset it. This removes the hack of setting and resetting
the WAYLAND_DISPLAY environment variable.
Creates a socketpair in WaylandServer and creates a ClientConnection for
Xwayland. The created file descriptor is passed to Xwayland through the
WAYLAND_SOCKET env variable.
QtWayland performs an eglInitialize in the main thread when for the first
time an OpenGL context/window is needed. In KWin's startup this happens
during initializing Scripting which creates a QDesktopWidget and triggers
the creation of a QWindow with a RasterGLSurface.
Calling eglInitialize in the main thread blocks as it calls wl_roundtrip.
We cannot just disable OpenGL as that would mean that we cannot use
QtQuick.
The workaround in this change is to create a QWindow with a
RasterGLSurface in a thread and call create on it. This ensures that
OpenGL gets initialized in the thread and doesn't block.
On Wayland we get the damage from the SurfaceInterface instead of
using a damage handle. This change ensures that the damage handle
interaction is only used on platform X11, while on Wayland we get
the damage from the SurfaceInterface directly.
Adds proper support for binding Wayland buffers to EGLImage.
The loading is split into a shm part and a Wayland buffer part,
so that both is supported.
Wayland buffer support is limited to format EGL_TEXTURE_RGB and
EGL_TEXTURE_RGBA. Other formats and multiple texture are not supported.
For Xwayland we need to have the Scene (and EglDisplay) created prior
to starting Xwayland and having X11. This requires creating the
Compositor before creating Workspace and starting Xwayland.
To support this the startup of Compositor is split into two parts:
prior and after Workspace creation.
The change might also be interesting for the kwin_x11 case as it could
result in the compositor being up in a quicker way.
