ade861d6de Refactor session code
At the moment, the session code is far from being extensible. If we
decide to add support for libseatd, it will be a challenging task with
the current design of session management code. The goal of this
refactoring is to fix that.

Another motivation behind this change is to prepare session related code
for upstreaming to kwayland-server where it belongs.

ae6e6dc63c [scripting] Port ScriptedEffects to QJSEngine
Summary:
QScriptEngine is deprecated for years and suffers bitrot.
Plasma hit one super major bug with it in 5.11.0 and has now ported
away.

Main porting notes:
- creating low level functions no longer exists
The old global functions are exposed on the ScriptedEffect instance
and then the QJSValue wrappers of the globalObject are modified to
trampoline the methods at a wrapper level.

- We can then use QJSEngine to automatically do argument error checking
rather than unmarshalling a QJSValue manually which significantly
reduces a lot of code.

- We can't make FPX2 a native type, so these are QJSValue args and
unboxed there.

Long term I want overloads for animate that take int/QSize/QPoint which
are native JS types, but that might be an API break.

Test Plan:
Hopefully comprehensive unit test which passes
Tested fade/fadeDesktop manually.

It's a very invasive change, so I expect some things will be broke
please help test any JS effects.

d23dab7be9 wayland: Fix handling of synthetic touch cancel events
In case the compositor wants to cancel a touch sequence, we need to
ignore subsequent touch motion and touch up events until a new sequence
is initiated by the user.

Previously, it was implicitly handled by clearing the mapping table
between the touch slots and touch ids generated by kwayland-server.

93e0265e4e Move source code to src/ directory
Once in a while, we receive complaints from other fellow KDE developers
about the file organization of kwin. This change addresses some of those
complaints by moving all of source code in a separate directory, src/,
thus making the project structure more traditional. Things such as tests
are kept in their own toplevel directories.

This change may wreak havoc on merge requests that add new files to kwin,
but if a patch modifies an already existing file, git should be smart
enough to figure out that the file has been relocated.

We may potentially split the src/ directory further to make navigating
the source code easier, but hopefully this is good enough already.

68c675d00d Make source code more relocatable
Occasionally, I see complaints about the file organization of kwin,
which is fair enough.

This change makes the source code more relocatable by removing relative
paths from includes.

CMAKE_CURRENT_SOURCE_DIR was added to the interface include directories
of kwin library. This means that as long as you link against kwin target,
the real location of the source code of the library doesn't matter.

With autotests, things are not as convenient as with kwin target. Some
tests use cpp files from kwin core. If we move all source code in a src/
directory, they will need to be adjusted, but mostly only in build
scripts.

b8a70e62d5 Introduce RenderLoop
At the moment, our frame scheduling infrastructure is still heavily
based on Xinerama-style rendering. Specifically, we assume that painting
is driven by a single timer, etc.

This change introduces a new type - RenderLoop. Its main purpose is to
drive compositing on a specific output, or in case of X11, on the
overlay window.

With RenderLoop, compositing is synchronized to vblank events. It
exposes the last and the next estimated presentation timestamp. The
expected presentation timestamp can be used by effects to ensure that
animations are synchronized with the upcoming vblank event.

On Wayland, every outputs has its own render loop. On X11, per screen
rendering is not possible, therefore the platform exposes the render
loop for the overlay window. Ideally, the Scene has to expose the
RenderLoop, but as the first step towards better compositing scheduling
it's good as is for the time being.

The RenderLoop tries to minimize the latency by delaying compositing as
close as possible to the next vblank event. One tricky thing about it is
that if compositing is too close to the next vblank event, animations
may become a little bit choppy. However, increasing the latency reduces
the choppiness.

Given that, there is no any "silver bullet" solution for the choppiness
issue, a new option has been added in the Compositing KCM to specify the
amount of latency. By default, it's "Medium," but if a user is not
satisfied with the upstream default, they can tweak it.

64ad9a61d8 Introduce ColorManager component
This change introduces a new component - ColorManager that is
responsible for color management stuff.

At the moment, it's very naive. It is useful only for updating gamma
ramps. But in the future, it will be extended with more CMS-related
features.

The ColorManager depends on lcms2 library. This is an optional
dependency. If lcms2 is not installed, the color manager won't be built.

This also fixes the issue where colord and nightcolor overwrite each
other's gamma ramps. With this change, the ColorManager will resolve the
conflict between two.

bdfb946267 Convert Night Color into a plugin
Night Color adjusts the color temperature based on the current time in
your location. It's not a generic color correction module per se.

We need a central component that can be used by both night color and
colord integration to tweak gamma ramps and which will be able to
resolve conflicts between the two. The Night Color manager cannot be
such a thing because of its very specific usecase.

This change converts Night Color into a plugin to prepare some space for
such a component.

The tricky part is that the dbus api of Night Color has "ColorCorrect"
in its name. I'm afraid we cannot do that much about it without breaking
API compatibility.

41d431de27 Adapt to input region changes in kwayland-server
SurfaceInterface::inputIsInfinite() has been dropped. If the surface has
no any input region specified, SurfaceInterface::input() will return a
region that corresponds to the rect of the surface (0, 0, width, height).

While the new design is more robust, for example it's no longer possible
to forget to check SurfaceInterface::inputIsInfinite(), it has shown some
issues in the input stack of kwin.

Currently, acceptsInput() will return false if you attempt to click the
server-side decoration for a surface whose input region is not empty.

Therefore, it's possible for an application to set an input region with
a width and a height of 1. If user doesn't know about KSysGuard or the
possibility of closing apps via the task manager, they won't be able to
close such an application.

Another issue is that if an application has specified an empty input
region on purpose, user will be still able click it. With the new
behavior of SurfaceInterface::input(), this is no longer an issue and it
is handled properly by kwin.

VirtualKeyboard class does not implement the relevant VirtualKeyboard

For now only rename of main class is done and dbus service is kept as-is

implemented fully, we can think of what to do wrt the dbus interface
later when we fully implement zwp_input_method_unstable_v1 protocol.

6acf35e4cc Avoid QPointer in return types of Input methods
QPointer is a really useful way to store a pointer over time.
It doesn't make have any value as a return value used by a short-lived
method.

There isn't a good copy constructor, it's effectively the same as
creating a new QWeakPointer reference that has to be cleaned up.

Testing if something is null is still the same. A new QPointer can be
made by the caller if it actually is needed.

Input handling is a very hot path called many times a frame, so it's
important to keep this light. focus() and at() are called a lot which
added up to slightly over 1% of CPU time when moving the mouse about.

d3cca65d39 Implement the layer-shell v1 protocol
The layer-shell protocol allows wayland clients to create surfaces that
can be used for building desktop environment components such as panels,
notifications, etc.

The support for the plasma-shell protocol will be dropped once plasma in
all its entirety is ported to the layer-shell protocol.

432cfb44c0 xwayland: Restart the Xwayland server after it has crashed
If the Xwayland process has crashed due to some bug, the user should
still be able to start applications in Xwayland mode. There is no reason
to restart the whole session just to be able to launch some application
that doesn't have native support for Wayland.

1fb9f6f13a Switch to SPDX license markers
The main advantage of SPDX license identifiers over the traditional
license headers is that it's more difficult to overlook inappropriate
licenses for kwin, for example GPL 3. We also don't have to copy a
lot of boilerplate text.

In order to create this change, I ran licensedigger -r -c from the
toplevel source directory.

19ad172584 Survive Xwayland crashes
If the Xwayland process crashes, it will bring down the entire session
together with itself. Obviously, we don't want that. At least, Wayland
clients should survive the crash.

This change refactors relevant X11 parts to handle Xwayland crashes in a
less fatal way.

In order to handle Xwayland crashes better, a pair of start() and stop()
methods had been introduced in the Xwayland class to allow starting and
stopping the Xwayland process at any moment.

If we detect that the Xwayland process has crashed, we will immediately
stop the Xwayland server, which in its turn will deactivate the socket
notifier and destroy all connected X11 clients. Unfortunately, a couple
of subtle changes in X11Client::releaseWindow() and Unmanaged::release()
had to be made to ensure that we are left with a valid state after the
Xwayland server has been stopped.

80a31ab4b7 Make setFrameGeometry() re-entrant for X and internal clients
If AbstractClient::setFrameGeometry() is called from a slot connected
directly to the frameGeometryChanged() signal, then is there a good
chance that kwin will fall into an infinite recursion. However, that's
the case with only X11 and internal clients.

The root cause of the infinite recursion is that both X11Client and
InternalClient compare the new geometry against the geometry before
update blocking. In order to fix the bug, we simply need to ensure that
updateGeometryBeforeUpdateBlocking() has been called before we start
emitting the frameGeometryChanged() signal.

Furthermore, a couple of tests were added to ensure that we won't hit
this subtle bug again.

2717252861 Partially revert a0c4a8e766
Unfortunately, a0c4a8e766 has a major bug
where clients that track focus events may get confused by focusToNull().

One such a notable example is Dota 2. It tracks the focus events to
minimize itself after the keyboard focus has been lost as well stop
playing music while it's in background. So, when we call focusToNull(),
Dota 2 will receive a corresponding FocusOut event and ask the window
manager to minimize it. It doesn't really matter that the FocusOut
event is going to be followed by a FocusIn event because when a window
is minimized, kwin will activate the next one in the focus chain.

Since those issues can't be fixed from the window manager's side, this
patch partially reverts a0c4a leaving only the autotest.

BUG: 424223

cf27128877 Update input transformation matrix when buffer geometry changes
Currently, we update the input transformation matrix for the focused
pointer surface only when the frameGeometryChanged() signal is emitted.
However, since the input transformation matrix is computed based on the
current position of the upper left corner of the main surface, it is
wrong to do so because the frame geometry is a logical geometry that
doesn't have any direct relationship with the buffer geometry, i.e. the
rect on the screen occupied by the main surface.

If the input transformation matrix gets out of sync, user may notice
that pointer events are "shifted."

This change introduces a new signal that's emitted when the input
transformation matrix has been changed. Input related components in kwin
can connect to it to keep a copy of the input transformation matrix in
SeatInterface in sync. Under the hood, the new signal is just an alias
for the bufferGeometryChanged() signal.

fc839d8b29 Fix testActivities
Currently, the test passes because the activities controller doesn't
have enough time to fetch all activities. So, the test client won't be
placed on the current activity.

Since the Workspace is now created before starting the Xwayland, we now
spin the event loop, which allows the activities controller to fetch the
list of all activities and so the test client will be placed on the
current activity, i.e. client->isOnAllActivities() will no longer return
true.

This change fixes wrong assumptions in the test and makes it robust.
