Summary:
The color correction manager doesn't make any specific assumptions about
underlying platform, e.g. whether it's x11, etc. The platform just
has to be capable of setting gamma ramps. Given that, there are no any
significant technical blockers for making this feature work on x.

Summary:
Represent outputs in the X11 session via AbstractOutput. For that we
move all Wayland specific parts of AbstractOutput into a new subclass
AbstractWaylandOutput and let the outputs of our Wayland backends inherit
from there.
This should allow us to get rid of the Screens class later on.
Test Plan: Manually in X session.

Summary:
On Wayland we cannot switch from OpenGL to QPainter compositor as this
would break any running OpenGL application. KWin registers it's
EGLDisplay to Wayland and without OpenGL this doesn't make sense any
more. We are not able to render OpenGL buffers in the QPainter
compositor.
While it's theoretically possible to switch from QPainter to OpenGL it
doesn't make any sense for the same reason. Any running OpenGL
application would be using llvmpipe and could not be switched to proper
OpenGL.
This change stores the selected compositing type in Platform and the
implementations can use it to restrict the supported compositors. On X11
we don't need this, all other Platforms implement the restriction. Thus
it's no longer possible to switch the backends at runtime.
Test Plan:
Adjusted tests run, no runtime test as gui doesn't support
switching to QPainter anyway.

Summary:
Let VirtualOutput be a child class of the new generic class Output.
This allows code sharing and a very similar behavior of the Virtual backend
in comparision to the Drm backend.
Test Plan:
Autotests succesful with two exceptions: The decoration input test fails on
testDoubleTap, row topLeft. This is to be expected because now the
ScreenEdgeInputFilter captures the event at position (0,0) before the
DecorationEventFilter can capture it. The autotest was adapted to take this
special case into account.
Also the lockscreen test fails, because the virtual output is currently missing
the physical size yet.

Summary:
In order to separate high-level properties of individual outputs from
hardware-specific ones and access these, introduce a new generic class Output.
Also make the DrmOutput class directly a child class of this generic class.
The long-term goal is to get rid of the Screens global object on Wayland and
instead directly work with Output objects on compositing level.
This should enable us long-term to do direct scanout to hardware planes, what
I predict needs this generic output representation at one point.
Test Plan: Manually.

Summary:
Qt objects are treated as identities so remove the copy constructor and
an assignment operator. See, http://doc.qt.io/qt-5/object.html#identity-vs-value
IIRC some Qt objects(like QImage) have copy constructor for implicit data sharing,
but VirtualOutput doesn't have anything to share.
Also, it [this patch] fixes a compiler warning:

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.

With Wayland KWin needs to provide certain services, which were provided
before that by the Xserver. One of these is gamma correction, which includes
the - by many people beloved - functionality to reduce the blue light at
nighttime. This patch provides the KWin part of that. It is self contained,
but in the end will work in tandem with a lib in Plasma Workspace and a KCM
in Plasma Desktop, which can be used to configure Night Color.
* Three modi:
** Automatic: The location and sun timings are determined automatically
(location data updates will be provided by the workspace)
** Location: The sun timings are determined by fixed location data
** Timings: The sun timings are set manually by the user
* Color temperature value changes are smoothly applied:
** Configuration changes, which lead to other current values are changed
in a quick way over a few seconds
** Changes on sunrise and sunset are applied slowly over the course of few
minutes till several hours depending on the configuration
* The current color value is set immediately at startup or after suspend
phases and VT switches. There is no flickering.
* All configuration is done via a DBus interface, changed values are tested
on correctness and applied atomically
* Self contained mechanism, speaks directly to the hardware by setting the
gamma ramps on the CRTC
* Currently working on DRM backend, extensible to other platform backends in
the future
* The code is written in a way to make the classes later easily extendable to
also provide normal color correction, as it's currently done by KGamma on X
Test Plan:
Manually with the workspace parts and added integration tests in KWin using
the virtual backend.

Summary:
So far KWin does not know which Compositors the platform actually
supports. This results in KWin happily trying to use the OpenGL
compositor on fbdev or the QPainter compositor on hwcomposer although
that is obviously going to fail as the platform doesn't support this.
By adding a pure virtual method all Platforms can define what they
support. In a later step the Compositor can use this to create an
appropriate scene and also perform proper fallback handling in case the
scene creation fails.

Summary:
Unfortunately a rather large change which required more refactoring than
initially expected. The main problem was that some parts needed to go
into platformsupport so that the platform plugins can link them. Due to
the rather monolithic nature of scene_opengl.h a few changes were
required:
* SceneOpenGL::Texture -> SceneOpenGLTexture
* SceneOpenGL::TexturePrivate -> SceneOpenGLTexturePrivate
* texture based code into dedicated files
* SwapProfiler code into dedicated files
* SwapProfiler only used in x11 variants
* Safety checks for OpenGL scene moved into the new plugin
* signal declared in SceneOpenGL moved to Scene, so that we don't need
to include SceneOpenGL in composite

If the system has a virtual device and KWin is run on virtual platform
we can assume the user intended that KWin should use the virtual device
and not a render node of the system.
This might fix the random test failures on build.kde.org (T6546).
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.

This change is similar to D7232 and moves the scene_qpainter into a
dedicated plugin. Compared to the XRender case it's more complicated as
the platform plugins need to implement a platform specific backend.
The base implementation for this part used to be in scene_qpainter. As
the idea is to completly move it away from KWin core it would be point
less to still have the backend definition in KWin core, but it cannot
be in the scene plugin as otherwise all platforms need to link the
plugin.
To solve this a new platformsupport subdirectory is added which contains
the scene platform backend as a static library. For the OpenGL scene such
a static library will also be required.
Test Plan: SceneQPainter test still passes, nested compositor still works

The Egl backend opens the drm device and creates a gbm_device from it.
From that it creates the EGL device. The EGL device outlives the EGL
backend (e.g. for compositor restart). So far the EGL backend destroyed
the gbm_device when going down which mesa did not like at all when a
new context got created on that EGL device.
Thus the ownership of gbm_device is also passed to the Platform so that
the compositor can be restarted.
This makes the TestSceneOpenGL no longer crash during the restart
compositor test.
Screens::init sets up a Qt::QueuedConnection connect from countChanged
to changed. This means that when first setting up the connection a
changed signal will be delivered in the next event cycle. This can mess
with other code. E.g. WaylandServer recreating outputs which can make
Xwayland crash or KWin internally crash.
To solve this problem we just need to make sure to set the output count
to the initial value before performing the init.

Summary:
The egl implementation for the virtual platform tries to use a render
node if available. If there is no render node it looks for a virtual
(kernel driver vgem) device, which unfortunately does not create a
render node in mainline kernel (there are patches in ChromiumOS).
For this the Udev wrapper is extended to search for renderNode devices
and for virtual dri devices.
If either render node or vgem dri device is found, it is tried to be
opened (without logind escalation) and on success a gbm device is
created on it. If any step of this fails the so far default behavior
of default device is tried for creating the EGLDisplay.
All of this is compile optional, so that the virtual platform does not
hard depend on udev and/or gbm.
Test Plan:
Auto tests which need OpenGL executed and verified that they
use the render node or vgem device.
