Summary:
Currently code base of kwin can be viewed as two pieces. One is very
ancient, and the other one is more modern, which uses new C++ features.
The main problem with the ancient code is that it was written before
C++11 era. So, no override or final keywords, lambdas, etc.
Quite recently, KDE compiler settings were changed to show a warning if
a virtual method has missing override keyword. As you might have already
guessed, this fired back at us because of that ancient code. We had
about 500 new compiler warnings.
A "solution" was proposed to that problem - disable -Wno-suggest-override
and the other similar warning for clang. It's hard to call a solution
because those warnings are disabled not only for the old code, but also
for new. This is not what we want!
The main argument for not actually fixing the problem was that git
history will be screwed as well because of human factor. While good git
history is a very important thing, we should not go crazy about it and
block every change that somehow alters git history. git blame allows to
specify starting revision for a reason.
The other argument (human factor) can be easily solved by using tools
such as clang-tidy. clang-tidy is a clang-based linter for C++. It can
be used for various things, e.g. fixing coding style(e.g. add missing
braces to if statements, readability-braces-around-statements check),
or in our case add missing override keywords.

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.

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 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:
This change fixes the hotspot calculation by introducing a dedicated
matrix to map the hotspot.
To better test the hotspot a small test application is added. The app
renders a red point at the cursor position and uses a cross for cursor
with the hotspot position being transparent. So if KWin renders the
cursor at the correct position a red point is visible in the center of
the cross. The test app supports several cursor hotspot positions:
* center (default)
* top left
* top right
* bottom right
* bottom left
To switch between the variants press the space key.
Test Plan:
Rotated screen, used test app to verify the hotspot is
correct. Also scaled display, still correct

Summary:
And finally nothing inside libkwineffects, libkwinglutils,
libkwinxrenderutils and kwineffect and kwin core uses KWin::display.
We are finally XLib free!
This change drops KWin::display and removes the include to QX11Info from
kwinglobals.h. And the libraries no longer need to link X11Extras. Due
to that removal a few seeming unrelated changes are required to add the
include where needed and linkage to X11Extras.
The biggest change is to x11 platform plugin which still needs the
display and caches it in the Platform and passes it to various places in
a way that the code doesn't need to be adjusted.

This change implements forwarding the pointer gestures to the new API in
SeatInterface.
While screen is locked no gestures are forwarded to the server. Also
locking the screen cancels any active gesture. Similar if areas inside
KWin would start to intercept the gestures, they need to be cancelled on
the Wayland SeatInterface.

Summary:
If KWin interacts with Libinput the RelativePointerManager interface
gets created on the Wayland server. The ForwardInputEventFilter does
forward the relative motion events in addition to the normal motion
events.
In order to properly support the relative motion events as they are
expected by the Wayland protocol the handling of pointer motion events
got slightly adjusted:
* Libinput Pointer event extended by the additional data points
* Libinput Pointer event carries the delta as a QSizeF instead of
QPointF
* PointerInputRedirection adjusted to take a pointer motion event with
more arguments
* Custom QMouseEvent subclass adjusted to carry the additional members
The DebugConsole is adjusted to show the relative motion events in
addition to the global position.
Test Plan:
Verified the manager object is created and verified the
events in DebugConsole. Unfortunately not aware of any test application.

Summary:
The idea is to have KWin provide a virtual keyboard. To support this
KWin uses the QT_IM_MODULE qtvirtualkeyboard and makes sure that the
QPA plugin loads it.
KWin has a new class VirtualKeyboard which acts as the focus object and
the "proxy" for input methods. The QPA plugin ensures that this is the
focusObject, so that all input method related events are sent to this
class. From there it will be possible to delegate to other applications
through the Wayland interfaces.

Summary:
The signals emitted by LibInput::Connection carry the Device for which
the input event was received. This Device is passed to the input handlers.
Custom event classes are added which extend QMouseEvent, QKeyEvent and
QWheelEvent respectively and expose the Device. The Device is only passed
around as a forward declared pointer, so even if compiled without libinput
support, it should still compile.
Event handlers which need to get access to the Device can now just cast
the event pointer to the custom class and access it. This can be used in
future to handle device specific key codes, etc.
As we don't have a proper event classes for touch events the event
handlers do not yet have access to the Device. Here the internal API
needs to be adjusted in future.

Summary:
The LibInput::Device provides a way to enable/disable the device.
This is used by the Connection to toggle all touchpad devices on/off
when the touchpad key is pressed. For this KWin "steals" the global
shortcuts from the touchpad kded.
Detecting what is a touchpad is unfortunately not tivial. The code
uses the following approach:
* it's a pointer
* it's not also a keyboard or touch screen
* it's at least one of the following:
** supports multiple tap fingers
** supports disable while typing
** supports disable on external mouse
If the code finds a touchpad and changes it's state successfully,
it triggers the touchpadEnabledChanged on Plasma's osdService.
Test Plan: Tested on notebook with toggle touchpad button

Summary:
The configuration file kcminput, group Mouse is parsed to decide whether
pointer devices should be in left handed mode. The config is applied
whenever a new device is added.
In addition the Connection listens to KGlobalSettings for a mouse
settings changed signal which might be emitted by the mouse KCM.
When such a signal is emitted, all pointer devices are reconfigured.
This allows to change the mouse handed settings on Wayland.

Summary:
The Device class wraps all the information we can get from libinput
about the device, like whether it's a keyboard, pointer, touch, etc.
In addition some more information is queried to figure out how "useful"
a device is. For a keyboard all alphanumeric keys are checked whether
they exist, for a pointer all (normal) buttons are queried.
All the information is exposed as Q_PROPERTY and used by the
DebugConsole. The DebugConsole gained a new tab "Input Devices" which
renders all devices and their properties in a tree view. When plugging
in/out a device, the model gets reset, so it's always up to date.
The new Device class can be used in future to configure the device,
e.g. disable touch pad, set mouse acceleration, etc.

Add an action type to screen edge show to allow raise/lower as well as
autohide. This uses the same atom, using a mask to separate type and
location.
The logic for handling geometry changes is moved from the screenedge to
the client so that we can handle both types without screenedge needing
to know what the raise is for.

Main purpose is to reproduce a crash if the parent window gets
destroyed before the transient. For this the following key combo
can be used:
t: show transient
k: close parent window
q: quit application
This currently causes reliably a crash in Deleted::copyToDeleted for
the connect of the mainClients.
With libinput we have the problem that we need to have privileges to
open the device files. In order to not need wrappers or suid bits, we
use logind. This means that kwin_wayland has to be the session controler.
A LogindIntegration is added to connect to logind and wrap the dbus
calls. This is based on the logind integration done for ksld in
ksmserver. The LogindIntegration is started by Workspace and the
InputRedirection tries to become the session controller and starts the
libinput integration only after this succeeded.
Libinput is an optional dependency for getting low level input events.
As opening the input devices requires root privs this is rather
pointless in the current state. But there is a small added test app which
can be executed with root privs to demonstrate the functionality. To
properly get input events we need a wrapper like it's used in weston.
So far the following is setup:
* opening devices found by udev
* forwarding keyboard events to InputRedirection
* forwarding pointer button events to InputRedirection
* forwarding pointer axis events to InputRedirection
* signals emitted for pointer motion events
Pointer motion events need some further work as they are provided
as delta events. We need to track that and map them properly.
Also missing are touch events due to me not having a touch screen.
It should be fairly simple to setup the touch events, though.
Also hotplugging of devices is not yet implemented.

So far the Unmanaged got released after an XCB_UNMAP_NOTIFY. This event
gets created after xcb_unmap_window or after xcb_destroy_window. In the
latter case the window is already distroyed and any of KWin's cleanup
calls will cause a BadWindow (or similar) error.
The idea to circumvent these errors is to try to wait for the
DESTROY_NOTIFY event. To do so the processing of the release is slightly
delayed. If KWin gets the destroy notify before the delay times out the
Unamanged gets released immediately but with a Destroy flag. For this a
new enum ReleaseToplevel is introduced and Unmanage::release takes this
as an argument instead of the bool which indicated OnShutdown. Also this
enum is added to Toplevel::finishCompositing so that it can ignore the
destroyed case and not generate an error.

This provides a new protocol intended to be used by auto-hiding panels
to make use of the centralized screen edges. To use it a Client can
set an X11 property of type _KDE_NET_WM_SCREEN_EDGE_SHOW to KWin.
As value it takes:
* 0: top edge
* 1: right edge
* 2: bottom edge
* 3: left edge
KWin will hide the Client (hide because unmap or minimize would break
it) and create an Edge. If that Edge gets triggered the Client is shown
again and the property gets deleted. If the Client doesn't border the
specified screen edge the Client gets shown immediately so that we
never end in a situation that we cannot unhide the auto-hidden panel
again. The exact process is described in the documentation of
ScreenEdges. The Client can request to be shown again by deleting the
property.
If KWin gets restarted the state is read from the property and it is
tried to create the edge as described.
As this is a KWin specific extension we need to discuss what it means
for Clients using this feature with other WMs: it does nothing. As
the Client gets hidden by KWin and not by the Client, it just doesn't
get hidden if the WM doesn't provide the feature. In case of an
auto-hiding panel this seems like a good solution given that we don't
want to hide it if we cannot unhide it. Of course there's the option
for the Client to provide that feature itself and if that's wanted we
would need to announce the feature in the _NET_SUPPORTED atom. At the
moment that doesn't sound like being needed as Plasma doesn't want to
provide an own implementation.
The implementation comes with a small test application showing how
the feature is intended to be used.

The test application can verify that KWin correctly interprets the
WM_NORMAL_HINTS as described in ICCCM section 4.1.2.3 for the
combination of min size, base size and size increment.
Introduces an optional dependency to xcb-icccm library. It's optional
as the last time we tried to use it build.kde.org didn't like it at
all. Thus it should be possible to disable building this test app if
the dependency is not found.
