There are use cases for the headers to be used, e.g. when implementing
wayland-specific workflows from an Effect.
In order to be able to use these, we also need to expose libkwin to be
imported as it carries the interfaces' symbols.

Qt requires xcb-icccm 0.3.9. On the other hand, 0.3.9 contains all the
types and functions used by kwin, so remove the corresponding
XCB_ICCM_FOUND checks to simplify the code.
The indirection contributes unnecessary complexity. The usage of
std::weak_ptr and std::shared_ptr complicates the things further, e.g.
---
Ideally, same should be done with TabBox and TabBoxHandler, but that can be done in another MR.
Makes it possible to follow the dbus service for locale configuration,
making it possible to have third parties integrate with Plasma.
This is done opt-in for now, it can be adopted generally in the future,
if necessary.
- Now only 1 GestureDirection enum
- Now only 1 registerGesture() call
- The 4 kinds of gesture (Pinch/Swipe) and (Touchpad/Touchscreen) in globalshortcuts.h/cpp are merged into 1 GestureShortcut
- Change from range to set of finger counts in gestures
No behavior should change, just a refactor.
This class can be used to create an anonymous file, for instance
to pass data between compositor and clients, through means of a
file descriptor, as is done in various Wayland protocols, notably
the keymap exchange.
It also implements sealing the file, so that it can be shared
between multiple clients without them being able to modify it.
If supported, memfd_create is used, otherwise a `QTemporaryFile`
is used.

ScreenPaintData provides a way to transform the painted screen, e.g.
scale or translate. From API point of view, it's great. It allows
fullscreen effects to transform the workspace in various ways.
On the other hand, such effects end up fighting the default scene
painting algorithm. For example, just have a look at the slide effect!
With fullscreen effects, it's better to leave to them the decision how
the screen should be painted. For example, such approach is taken in
some wayland compositors, e.g. wayfire, and our qtquick effects already
operate in similar fashion.
Given that, strip the ScreenPaintData of all available transforms. The
main motivation behind this change is to improve encapsulation of item
painting code and simplify model-view-projection code in kwin. It will
also make the job of extracting item code for sharing purposes easier.
Anything in xcb_ structs are always in X local, all member variables
aside from buffers are in kwin local space.
This patch ignores a few paths that are not relevant on wayland.
The XRender backend has been removed, leaving most of KWinXRenderUtils unused.
The few features that are still used, notable `XRenderPicture` and pict format
are moved into the x11/common directory.

This makes KWin switch to in-tree copy of KWaylandServer codebase.
KWaylandServer namespace has been left as is. It will be addressed later
by renaming classes in order to fit in the KWin namespace.
Effect loading is already tested using integration tests, for example
the maximize test verifies that the maximize effect is loaded _and_ it
actually does something useful when a window is maximized or restored,
testScriptedEffectLoader only verifies that the effect is loaded, which
is less helpful than what integration tests provide us.
But perhaps the main problem with these tests is that they require us
building a mockverse around them. This litters code with ifdef
preprocessor directives and makes changing such code a living nightmare.
Another problem with these two tests is that they cannot use OpenGL
because it means mocking OpenGL, which we obviously not going to do.
With integration tests, it's not a problem.
The bottom line is that unit tests can be useful but they make life
notoriously difficult when it comes to testing components that depend on
other components.
This improves file organization in kwin by putting backends in a single
directory.
It also makes easier to discover kwin's low level components for new
contributors because the plugins directory may come as the last place to
look for. When one hears "plugin", the first thing that comes to mind is
regular plugins, not low level backends.
The main motivation behind this change is to prepare kwin for importing
kwayland-server code in libkwin.
As is, builtin effects are linked with libkwin. Some builtin effects
have wayland specific code. If we move wayland stuff in libkwin, there's
going to be a circular dependency between kwin4_effect_builtins and
libkwin targets.
This change intends to break that dependency by linking builtin effects
to kwin executable.
The main issue with that is that EffectLoader would need to discover the
effects indirectly. QStaticPlugin is used for that purpose.
Besides breaking the cyclic dependency, it makes builtin effects use the
same plugin infrastructure in libkwineffects that external effects use.
Metadata in src/effects/effect_builtins.cpp was converted in a list of
python dictionaries, which was fed to a python script that generated
main.cpp and metadata.json files.
With the LEDs enum being defined in kwinglobals.h, wayland_server.h
won't need to include keyboard_input.h, which is good for compilation
times and wayland_server.h will drag less stuff, e.g. QtWidgets (input.h
includes QAction)
Startup code in plasmashell was changed so xsetroot is not called
anymore, which is sort of fine.
Unfortunately (or not?), it exposed a bug in kwin. Cursor::x11Cursor()
only works in the standalone X11 session.
On Wayland, Cursor::x11Cursor() will return XCB_NONE which results in
seeing cross cursor when there should be arrow cursor.
This change moves xcb_cursor_t look up code from X11Cursor to the base
Cursor class. In hindsight, I would like to introduce a window manager
class where the xcb cursor and other x11 specific code can be moved in
the future for better encapsulation of platform-specific code.

Due to the screen edges test not being an integration test, it's very
hard to change output related code in libkwin. screens.cpp needs to have
a few ifdefs to successfully compile.
This change rewrites the screen edges test as an integration test in
order to allow us using other components of kwin in screens.cpp and
screenedge.cpp without ifdef guards.
It's not a one-to-one port.
Re-use Qt's implementation of handling non-Latin layouts here
For full ASCII range support (Alt+`, etc.) Qt needs to be patched still,

BUG: 375518
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.

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.
This logs to a tracefs filesystem which can be viewed in tools such as
gpuvis to see precise timings of activities in relation to other trace
markers in X or graphic drivers.
This patch is loosely based on D23114. Though modified with thread
safety, support for string building, and a RAII pattern for durations.
Ultimately that expanded it somewhat.
At the moment, the Screens class is convoluted with ifdefs because of
MockScreens.
The goal of this change is to reduce the number of usages of the
MockScreens class so it is possible to get rid of the ifdefs.
Summary:
As is KWin only had 1 Cursor which was a singleton. This made it impossible for
us to properly implement the tablet (as in drawing tablets) support and show where
we're drawing.
This patch makes it possible to have different Cursors in KWin, it makes all the
current code still follow the mouse but the tablet can still render a cursor.
Test Plan: Tests pass, been using it and works as well as before but with beautiful tablet cursors.

Summary:
This functionality will instead be implemented in KScreen such that manual and
automatic output rotation can be used and configured through a single UI in
unison together.
