Summary:
EffectQuickView/Scene is a convenient class to render a QtQuick
scenegraph into an effect.
Current methods (such as present windows) involve creating an underlying
platform window which is expensive, causes a headache to filter out
again in the rest of the code, and only works as an overlay.
The new class exposes things more natively to an effect where we don't
mess with real windows, we can perform the painting anywhere in the view
and we don't have issues with hiding/closing.
QtQuick has both software and hardware accelerated modes, and kwin also
has 3 render backends. Every combination is supported.
* When used in OpenGL mode for both, we render into an FBO export the
texture ID then it's up to the effect to render that into a scene.
* When using software QtQuick rendering we blit into an image, upload
that into a KWinGLTexture which serves as an abstraction layer and
render that into the scene.
* When using GL for QtQuick and XRender/QPainter in kwin everything is
rendered into the internal FBO, blit and exported as an image.
* When using software rendering for both an image gets passed directly.
Mouse and keyboard events can be forwarded, only if the effect
intercepts them.
The class is meant to be generic enough that we can remove all the
QtQuick code from Aurorae.
The intention is also to replace EffectFrameImpl using this backend and
we can kill all of the EffectFrame code throughout the scenes.
The close button in present windows will also be ported to this,
simplifiying that code base.
Classes that handle the rendering and handling QML are intentionally
split so that in the future we can have a declarative effects API create
overlays from within the same context. Similar to how one can
instantiate windows from a typical QML scene.
Notes:
I don't like how I pass the kwin GL context from the backends into the
effect, but I need something that works with the library separation. It
also currently has wayland problem if I create a QOpenGLContext before
the QPA is set up with a scene - but I don't have anything better?
I know for the EffectFrame we need an API to push things through the
effects stack to handle blur/invert etc. Will deal with that when we
port the EffectFrame.
Test Plan: Used in an effect

Summary:
Qt's metaobject is rather sensitive with scope resolution.
Foo::Bar and Bar don't always match to a Qt metaobject, even if they
refer to the same thing to a compiler. Here we register
X11Compositor::SuspendReason but Q_ARG uses SuspendReason and they don't
match. This leads to a runtime failure where the method isn't invoked.
Rather than fixing metaobject usage, port the whole thing to lambdas
which does better compile time checking and is generally nicer to read.
BUG: 412353
Test Plan:
Ran xprop to block compositing. Compositing was blocked.

Summary:
Currently the init method is just a big pile of connects to lambdas,
which makes the code very difficult to read and moreover to change.
This change moves most of those lambda to handleFoo methods so one has
more clear view of what the init method is actually doing.

Summary:
Currently Night Color doesn't handle time zones very well. For example,
if the user's time zone is UTC-8, then computed timings of sunrise and
sunset (in UTC) will be a bit gibberish as sunset occurs before sunrise
rather than vice versa.
This change switches relevant parts of Night Color to local time in
order to fix expectations about the order of morning and evening in
updateSunTimings() method as well to simplify the code a bit (dealing
with UTC and local time can be painful sometimes).

Summary:
Currently each managed X11 client is represented with an instance of
Client class, however the name of that class is very generic and the
only reason why it's called that way is because historically kwin
was created as an x11 window manager, so "Client" was a sensible choice.
With introduction of wayland support, things had changed and therefore
Client needs to be renamed to X11Client in order to better reflect what
that class stands for.
Renaming of Client to X11Client was agreed upon during the last KWin
sprint.
Test Plan: Compiles, the test suite is still green.

Summary:
It doesn't belong with advanced compositing settings as it's quite user
friendly, and we also want to adjust other animation speeds. May as well
do it together.
In the current form all compositing is still completely reinitiliased
like with the previous slider. Change notifications come in the form of
KConfigWatcher rather than our own bespoke update interface.
Test Plan:
Moved new slider, minimised a window.
It still behaved as expected.

Summary:
Currently KWin::GLTexture is a nice wrapper for creating a GL texture
and performing various operations including rendering.
In a pending patch I want to render the FBO from a QQuickScene directly,
where we have an underlying texture already, but it makes sense to
re-use this class for the rendering. A similar need is in haagch's kwin
VR patchset.
This patch adds a constructor to GLTexture that takes an externally
managed texture and provides the relevant useful KWin features.

If something handled by the low level filtering ever calls postEvent we

Fortunately there's a flag to separate generated and core events

Don't put method definitions in the header file of XdgShellClient class
as it makes the code visually inconsistent. InternalClient is a good
example of how the header file of a subclass of AbstractClient class
should look like.
This change also cleans up the order of things in the header file, thus
making it a bit more obvious where new things should go.
Summary:
If we get a key event for which
if (m_xkb->shouldKeyRepeat(key) &&
waylandServer()->seat()->keyRepeatDelay() != 0) fails
m_key will be unitialised and on release we have a compare against
unitialised memory.
Won't do any harm, it'll just stop a timer that isn't running, but
valgrind complains.
0 is the value QKeyEvent uses when nativeScanCode is unknown so a safe

Summary:
This change removes all traces of wl-shell in the test suite. That's a
prerequisite for dropping wl-shell support in KWin.
Given that wl-shell and xdg-shell are not interchangeable, some tests
were removed and initialization sequence in some tests was adjusted.
The most notable change is ensuring that each plasmashell window sets
its role and initial position before committing the surface. Setting
those properties before the first surface commit is important because
our window placement code needs to know window type in order to
avoid maximizing panels, popups, etc.

Summary:
So far wayland was used by internal clients to submit raster buffers
and position themselves on the screen. While we didn't have issues with
submitting raster buffers, there were some problems with positioning
task switchers. Mostly, because we had effectively two paths that may
alter geometry.
A better approach to deal with internal clients is to let our QPA use
kwin core api directly. This way we can eliminate unnecessary roundtrips
as well make geometry handling much easier and comprehensible.
The last missing piece is shadows. Both Plasma::Dialog and Breeze widget
style use platform-specific APIs to set and unset shadows. We need to
add shadows API to KWindowSystem. Even though some internal clients lack
drop-shadows at the moment, I don't consider it to be a blocker. We can
add shadows back later on.
