This merges Window::clientMinimized() and Window::clientUnminimized()
signals with the Window::minimizedChanged() signal to simplify some
code.
The avoid animation flag has been dropped because its main usage is to
avoid playing animation during window initialization. But it's not possible
to trigger minimize animation at that moment. API-wise it's better to avoid
having such flags too and rely on surface role to decide whether to play a
given animation.
This signal exists as a convenience helper, but it's not always emitted
as it's advertised to work. Instead of fixing it, let's drop the signal
to simplify virtual desktop code. Its effects can be accomplished by
monitoring Window::desktopChanged() and VirtualDesktopManager::currentChanged()
signals in effects and scripts where needed.
Checking if the pointer needs to be confined before doing `std::clamp` on
the position is useless and causes problems. With this change, the pointer
will always be confined to exactly the screen, without any fractional offsets.
BUG: 461911
Use input device specific apis to change the position of the cursor. The
main reason to do so is to break the assumption that Cursor position is
the same as pointer position, which I would like to rely on later to
merge tablet and pointer cursors.
This installs a socket notifier onto our xwayland socket, when a user
connects we launch xwayland. The client then connections once kwin has
established itself as the compositor.
For a full desktop plasma session this patch effectively does nothing
too useful as we still start kcminit and make xrdb calls on startup
which in turn will launch X, but for the same reason this patch should
be harmless now as we're still processing the xrdb calls before any
clients will connect.

testLockScreen uses !eventSpy.wait() expression to check whether the
given signal is emitted. QSignalSpy::wait()'s default timeout is 5s,
which is too much. We don't need to wait that much, in fact, even
wl_display_sync() would suffice. In either case, let's pass explicit
timeout of 10ms which should be good enough.

* Allow to do quick tiling to custom tile geometries, windows will be snapped to tiles when dragged with the shift modifier pressed.
* Tile geometries are screen specific.
* The global shortcut Meta+T will trigger a fullscreen configuration ui as a QML effect for the tiles which allows to add, remove and resize tiles
* UI and behavior is a bit similar to the Windows Fancy Zones addon: https://docs.microsoft.com/en-us/windows/powertoys/fancyzones
* Its main scope is to help the workflow with very big monitors, especially ultra wide ones, where most application don't make sense maximized to the full screen (eventually also support games to be full screened to a given tile instead of the whole screen)
* it should get also some bindings for scripting, as its ain goal is not to replicate other popular tiling window managers, but should give the popular kwin tiling scripts to have a more robust infrastructure
* it will eventually get support for a set of predefined layouts, but this is for a second phase
BUG: 438788
We use KWIN_NAME, KWIN_INTERNAL_NAME_X11 and KWIN_INTERNAL_WAYLAND
properly only in a few places. In other, we use hardcoded names.
Let's not bother and hardcode kwin names everywhere rather than have one
foot in and one foot out, it's simpler.
Due to being a compositor, kwin has to conform to some certain
interfaces. It means a lot of virtual functions and function tables to
integrate with C APIs. Naturally, we not always want to use every
argument in such functions.
Since we get -Wunused-parameter from -Wall, we have to plumb those
unused arguments in order to suppress compiler warnings at the moment.
However, I don't think that extra work is worth it. We cannot change or
alter prototypes in any way to fix the warning the desired way. Q_UNUSED
and similar macros are not good indicators of whether an argument is
used too, we tend to overlook putting or removing those macros. I've
also noticed that Q_UNUSED are not used to guide us with the removal no
longer needed parameters.
Therefore, I think it's worth adding -Wno-unused-parameter compiler
option to stop the compiler producing warnings about unused parameters.
It changes nothing except that we don't need to put Q_UNUSED anymore,
which can be really cumbersome sometimes. Note that it doesn't affect
unused variables, you'll still get a -Wunused-variable compiler warning
if a variable is unused.
The entire approach behind that test is wrong. Even slight changes in
one pixel can make the test fail. There's no human-friendly way to
determine what the difference between reference and actual frames are.
The reference frame is generated in code rather than from an image on
the disk, which makes the tests even more error-prone.
The test is flaky too and constantly blocks merging patch submissions.
We need a different way to test rendering results, not what
testSceneQPainter currently does. Normally, I would say that we need
to add such an infrastructure before dropping the test, but it makes the
merging process so inconvenient and the test doesn't really bring any
value, it tests really basic cases which are noticeable right away after
launching kwin.
