Summary:
I could never reproduce the crash, but we know from gdb that it's from
the decorationSettings object
We are setting the same QObject instance as a context property in
multiple contexts at once. This is already slightly odd especially from the POV of
Qt's internal property cache.
Given we want one object to be exposed to all contexts, we can expose it
to the parent context only once and achieve the same result in a simpler
way.
BUG: 411166
Test Plan:
Verified opening and closing system settings still worked for me.
I could never reproduce the original crash.

Summary:
Context behaviour subtly changed in Qt5.14 which has exposed some
questionable things in this KCM.
Auorae::Decoration is a context property of the loaded QML.
QObject::~QObject signals it's own deletion before deleting children.
This means the bindings of loaded QML update in particular
aurorae.qml
DecorationOptions {
id: options
deco: decoration
}
DecorationOptions has a pointer to the previously set decoration which
is now dangling, and we crash.
Rather than adding more guards and smart pointers in DecorationOptions,
this patch deletes the QQmlContext before deleting the context
properties that we expose.
It also moves unreferring the shared qmlcontext we inherit from till
after we've deleted the child context, because it didn't make sense.
Test Plan:
Opened KCM
Closed the KCM
didn't crash

We have lots of inconsistency at the moment in CMakeLists.txt files. Most
of it is due to kwin being a very old project. This change hopefully fixes
all of it.
Summary:
KWin blits contents into a QImage raster buffer. Because of this we
don't need our underlying GL surface to be double buffered as it
effectively makes the whole thing tripple buffered.

Summary:
Aurorae has a timer between request update and updating the contents.
This makes some sense.
However on initial creation we want to snap the contents immediately as
otherwise we may be out by a frame between a new window being mapped and
the window decoration being rendered.

Ran with Auroae
Windows opened immediately seemed to have a deco straight away

Summary:
So far we were following a bit unique and rare doxygen comment style:
/**
* Contents of the comment.
**/
Doxygen comments with this style look balanced and neat, but many people
that contribute to KWin don't follow this style. Instead, they prefer
more traditional doxygen comment style, i.e.
/**
* Contents of the comment.
*/
Reviewing such changes has been a bit frustrating for me (so selfish!)
and for other contributors.
This change switches doxygen comment style in KWin to a more traditional
style. The main reason for doing this is to make code review process easier
for new contributors as well us.

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.
Test Plan: Compiles.

Workaround QtBug-68997
Deleting of a RenderControl/render controlled window triggers deletion
of other queued deleted items, putting KWin in a corrupt state. See Qt
bug report.
Deleting this queued means we know we don't have anything else going on
in the stack which should make this somewhat safe.

x and y are always relative to the parent, adding parent.width to

Original author meant just "x: parent.width-1"
But we may as well just use anchors. Programatically it comes out the
same.

No more weird vertical lines in the KCM when view is slightly less than 2 previews wide.
Modded colour to hardcoded "red" for easier visualisation, checked it looked ok when set as a real deco.

Summary:
KWin was quite good in ensuring that you don't need to install by
passing paths to the tests. The new way is much nicer, so code is
adjusted for the new way. Also if we require a newer ECM in future we
need to support the new way.
No guarantee that the tests don't pick something up from the system env,
that needs more testing.

Summary:
For software QtQuick rendering we want to create a pixmap buffer and
render our contents in there.
m_rendercontrol->grab does this, but also covers the GL side in pretty
much the same way that we were currently doing.
In doing so I found a bug in Qt, that's submitted upstream, and also worked round.
Test Plan:
Tested with forced software mode, could see an Aurorae decorations
Tested without (so normal code), could see an Aurorae decorations
Tested wayland on nvidia with software rendering, didn't freeze
Whether we then end up using GL, painter or xrender rendering is irrelevant
(but I tested two of them anyway)

Summary:
On Wayland aurorae was creating a lot of stress for the system and
basically turning the system unusable in a short time. This was due to
a recursion starting to create OpenGL contexts. The window created a
decoration (aurorae) which created a QQuickWindow. For that KWin creates
an internal window which in turn triggers the creation of a window
decoration and so on and on.
By simply setting the render QQuickWindow as frameless we can prevent
this recursion.
Test Plan: Tested on Wayland and X11. On Wayland the recursion is gone.
