Summary:
We have a mix of different doxygen comment styles, e.g.
/*!
Foo bar.
*/
/**
* Foo bar.
*/
/** Foo bar.

/**

/**

To make the code more consistent, this change updates the style of all
doxygen comments to the last one.

Summary:
The initial state for user enabled is now read from config. In addition
a DBus interface is provided exporting this property. This allows
KScreen to determine whether automatic screen rotation is available and
whether the user has it enabled or not.
Furthermore KScreen can change the property and this gets stored into
the configuration. Thus KScreen can offer a user interface to
enable/disable automatic screen rotation as well as enabling/disabling
the manual rotation based on the current user settings.
Test Plan:
Not yet tested, coded on the system which doesn't have an
orientation sensor

Summary:
This change finds the screen for a touch screen device based on:
* number available screens
* output name defined on the touch screen device
* internal screen
* and physical size
The id of the screen is stored in the Device allowing to adjust the
touch points accordingly. This means instead of transferring to the
combined display size the touch points are transferred into the output
space and the position of the output is added. Thus in a multi screen
system the touch points are properly mapped to the output.
Furthermore the screen orientation is passed to the Device and a
calibration matrix is set accordingly. Thus a transformed screen has the
touch screen transformed accordingly.
Please note that this only affects libinput on Wayland and not on X11!
The x11 standalone platform needs to gain similar code.

Summary:
This change introduces an OrientationSensor class which wraps a
QOrientationSensor. The OrientationSensor is hold by Screens and gets
enabled if Screens knows about an internal (e.g. LVDS) display which
supports rotation. In addition the OrientationSensor holds an KSni to
enable/disable the automatic rotation support.
The drm platform plugin is adjusted to make use of the OrientationSensor.
The API is defined in a way that this can also be implemented on other
platforms supporting rotation. Most important are hwcomposer and X11
standalone. The latter should be straight forward as rotation is provided
through XRandR. The former needs addition for rotation support first.

Summary:
Allows to share the implementation in a better way and is a requirement
to get the Screen implementation in the QPA plugin to be based on
KWin::Screens instead of KWayland::Output.

Summary:
KWin::displayWidth and KWin::displayHeight are bound to X11 which
doesn't make much sense on X11. In addition KWin internally knows
the overall display dimensions through the Screens singleton class.

Summary:
Provides a virtual method in Screens where backends can supply the scale
of each screen, this is then set on each output.
For the X windowed backend this value is taken from a command line
parameter.
Test Plan:
Ran windowed mode with --scale 1 and 2
then kate --platform=wayland from another screen.
On the latter case UI elements were scaled up correctly

For this AbstractBackend has a new virtual screenGeometries() method
which returns a QVector<QRect>. By default it's just one QRect at 0/0
with the size of the one screenSize().
X11, Wayland, virtual, Framebuffer and hwcomposer have extremely
similar screens implementations. Let's add a base implementation
for them as a BasicScreens.
Each of the backends becomes a plugin. This allows kwin_wayland to load
the requested plugin and kwin itself doesn't need to link all the
libraries needed. E.g. libdrm is no longer linked if running kwin_x11.
Also this allows to create backends for the non-standard EGL platforms
(examples could be raspberrypi or Android devices).
A new implementation of the Screens interface is added which uses XRandR
directly instead of relying on QDesktopWidget. The implementation is
provided in a new implementation file screens_xrandr.cpp.
XRandRScreens comes with a unit test. Unfortunately it's rather difficult
to provide a proper unit test against XRandR. Xvfb (which is obviously
used on the CI system) doesn't provide the XRandR extension. Also on a
"normal" developer system one would not want to just execute the test as
the results are not predictable (number of available outputs?) and the
test would mess up the setup resulting in nobody wanting to execute the
test.
As a solution to both problems the unit test starts Xephyr as a nested
X server. This allows to have at least some limited tests against XRandR.
Nevertheless there are a few things which I was not able to test:
* multiple outputs
* no output at all
The nested X Server approach makes the interaction rather complex. Qt
opens it's connection against the main X Server thus QX11Info provides
a wrong connection and also KWin::connection() which is heavily used by
xcbutils and thus all the RandR wrappers have the wrong connection. To
circumvent this problem the test is GUILESS. In case it would call into
any code using QX11Info, it would probably either runtime fail or crash.
REVIEW: 117614
Uses the information provided by the Wayland outputs to setup the data
about the available screens.
In order to properly work together with the X Server the implementation
syncs the data to the X system using XRandR. If XRandR is not available
this is most likely going to not work correctly.
Screens provides a size which is constructed from the size of
the bounding geometry of all screens and provides an overload taking
an int to return the size of a specified screen. For geometry() a new
ovload is added without an argument, which is just a convenient wrapper
for QRect(QPoint(0, 0), size()).
Both new methods are exported to effects and scripting as new
properties there called virtualScreenSize and virtualScreenGeometry.
The (virtual) size gets cached in screens and is updated whenever the
count or geometry changes.
Construction of Screens is slightly changed by moving the init code
from ctor into a virtual method init(). Reason is that we ended in
a loop with accessing the singleton pointer before it was set.

REVIEW: https://git.reviewboard.kde.org/r/111811/
Following the approaches of other split out functionality Screens is a
singleton class created by Workspace.
The class takes over the responsibility for:
* screenChanged signal delayed by timer
* number of screens
* geometry of given screen
* active screen
* config option for active screen follows mouse
The class contains a small abstraction layer and has a concrete subclass
wrapping around QDesktopWidget, but the idea is to go more low level and
interact with XRandR directly to get more detailed information.
All over KWin the usage from QDesktopWidget is ported over to the new
Screens class.
