This implements the server part of the screen management protocol. The
protocol is implemented as a wayland protocol.
It provides the following mechanisms:
- a list of outputs, close to wl_output, with additional properties for
enabled, uuid, edid, etc.. These OutputDevices correspond to a
connected output that can be enabled by the compositor, but is not
necessarily currently used for rendering.
- a global OutputManagement, which allows creating config objects, one
per client. The client can make changes to the outputs through
setScale(outputdevice*, scale) for example.
- an OutputConfiguration resource, that can be handed to a client and
used for configuration. Changes are double buffered here. Only after
OutputConfiguration.apply() has been called, the changes are relayed
over the global OutputManagement.
The compositor is responsible to handle changes.
For a more detailed description, see the API docs in especially
outputconfiguration.h.

Adding support for a org_kde_kwin_dpms interface. On server side
Dpms is mostly bound to the OutputInterface exposing just a very
small manager. Whether Dpms is supported and which mode is used is
tracked directly on the OutputInterface.
a protocol to activate the blur behind windows and to
optionally set a sub region of the window where to apply
the blur to, in case the window is shaped

The shadow protocol is inspired by the KWin's X11 protocol and the
DecorationShadow in KDecoration2.
A shadow is attached to a surface (after a commit on surface) and
consists of several image parts (represented through a buffer):
* top-left
* top
* top-right
* right
* bottom-right
* bottom
* bottom-left
* left
In addition there is an offset on each side.
For more information see also the X11 protocol described at [1].
Note: the protocol is currently missing documentation and changing
the shadow is not yet properly delegated to the server API.

This interface allows a client to fake input events and the server
might use them. There is an authentication mechanismn in place which
requires the server to mark the client as authenticated in order for
any events to be emitted at all.
This interface is intended for use cases like kdeconnect which allows
to remote control a device.
The idle time interface is modelled for the use cases of the KIdleTime
framework to allow providing a Wayland specific implementation.
It supports registering idle timeouts which are triggered on server
side if there has not been any user activity on the seat for the
requested amount of time. Once user activity resumes a resume from idle
signal is emitted.
In additon there is the possibility to simulate user activity which
simulates the resume from idle.
The Qt surface extension is a small protocol to allow exchanging
additional data between QWindows and the compositor. What we are
currently only interested in is the possibility to close a surface
from the Compositor.
Protocol description is copied from QtWayland 5.4.2 branch.
Uses eglQueryWaylandBufferWL (if available) to determine the size of the
buffer. In order to do so, the server library links against egl (1) and
one needs to register the EGLDisplay in Server::Display by the user of
the library. For this a new method Display::setEglDisplay is added.
1: not using epoxy as it doesn't wrap the Wayland interfaces yet.
The ClientConnection is managed by Display. Whenever one tries to
get a ClientConnection for a wl_client* and it doesn't exist yet a
new one will be created and a clientConnected signal will be emitted.
Also there is a clientDisconnected signal.
ClientConnection provides access to pid, uid and gid. The idea is
to extend it to provide access to all the resources created for the
client.
The Resource base class is supposed to be used by all interface
classes which get created for a wl_resource.
Most interface classes are adjusted, but there are some exceptions:
* BufferInterface: is different as the wl_resource is already created
* PointerInterface and KeyboardInterface: those two need changes, the
implementation differs from all other interface implementations.
New base class KWayland::Server::Global which all Interface classes
for a wl_global inherit. Furthermore there is a shared base class
for all the Private classes of that type.
Only selection part is implemented, drag'n'drop still needs to be
implemented.
Unit test is not properly testing whether the data can be transferred.
This needs some better architecture to have multiple processes which
perform the source and target part.
This implements the subcompositor and subsurface protocol on both
Client and Server side.
Client:
New classes SubCompositor and SubSurface. The SubCompositor can be
created through the Registry and creates the SubSurface which is
bound to a Surface and has a parent Surface. The SubSurface class
provides convenient wrappers for all calls exposed in the
wl_subsurface interface.
Server:
New classes SubCompositorInterface and SubSurfaceInterface. Support
for all commands is added, though the API probably still can need
some fine tuning. The synchronized vs. desynchronized behavior is
not yet exposed in the API. This could also be delegated towards
the user of the library.
This makes it possible to install and then use it. Installation is still
commented since we can't give enough stability guarantees for now.
In detail:
- do not actually install headers
- generate the export header into Wayland/Server
- include it from there
REVIEW:120579
Framework style build system which generates two libraries:
* KF5WaylandClient
* KF5WaylandServer
autotests are adjusted to compile again. They need to be changed to
use the libraries once the export header gets generated.
