Summary:
This change ensures that KWin can be built with a version of KWS that
doesn't have any deprecated stuff. I assume that no distro ships such
builds of KWS and it's only a developer thing.
I didn't backport KWINDOWSYSTEM_BUILD_DEPRECATED_SINCE macro because
the next release of Plasma (5.18) depends on KF 5.66.

Summary:
Scene opengl has a callback for when we have a GL error. One of the
handlers for an error calls scheduleVboReInit the history shows it was a
forerunner to the GLX_NV_robustness_video_memory_purge but resetting
only one tiny part based on debug output.
When we get here we schedule a reset of the vertex buffer, via a timer.
When the timer is caled we have no idea what GL context was last
current, if it's not the currect context then the main scene
GLVertexBuffer will be deleted but not correctly re-initialised.
We have two very common crashes with a corrupted
GLVertexBuffer::streamingBuffer() which would match up perfectly.
Given that we now have a proper mechanism to reset the entire scene, we
don't need this timer based hack and resolve that problem.

Summary:
Quite long time ago, window decorations were painted on real X11 windows.
The nicest thing about that approach is that we get both contents of the
client and the frame window at the same time. However, somewhere around
KDE 4.2 - 4.3 times, decoration rendering architecture had been changed
to what we have now.
I've mentioned the previous decoration rendering design because it didn't
have a problem that the new design has, namely the texture bleeding issue.
In the name of better performance, opengl scene puts all decoration parts
to an atlas. This is totally reasonable, however we must be super cautious
about things such as the GL_LINEAR filter.
The GL_LINEAR filter may need to sample a couple of neighboring texels
in order to produce the final texel value. However, since all decoration
parts now live in a single texture, we have to make sure that we don't
sample texels that belong to another decoration part.
This patch fixes the texture bleeding problem by padding each individual
decoration part in the atlas. There is another solution for this problem
though. We could render a window into an offscreen texture and then map
that texture on the transformed window geometry. This would work well and
we definitely need an offscreen rendering path in the opengl scene,
however it's not feasible at the moment since we need to break the window
quads API. Also, it would be great to have as less as possible stuff going
on between invocation of Scene::Window::performPaint() and getting the
corresponding pixel data on the screen.
There is a good chance that the new padding stuff may make you vomit. If
it does so, I'm all ears for the suggestions how to make the code more
nicer.

Summary:
We currently see a gap on transformed windows between the window and the
top decoration.
This is partly the atlas bleed on the decoration, and partly a bleed on
the window content itself.
On X11, the window we composite is the frame window - which is a larger
texture containing a transparent border where the frame normally would
be. When we sample with a linear filter we include these texels. Hence
GL_CLAMP_TO_EDGE doesn't work.
Vlad's patch to composite the correct window, not the frame was my
preferred approach, but we had to revert it as it caused an issue with
xwayland :(
Half pixel correction nearly worked, but caused blurry fonts.
This patch resolves it in the fragment shader used by effects doing
transforms. We pass the real texture geometry of the window to the
client with a half pixel correction. Any samples outside the outer half
pixel are then clamped within bounds.
Arguably a hack, but solves the problem in a comparatively
non-invasive way.

The ClockSkewNotifier provides a convenient way for monitoring system
clock changes. One of the key ideas was to hide platform details from
users of the class. This allows us to add a QTimer fallback path for
operating systems that don't provide anything to detect system clock
changes.
In long term, I would like to move the new class to Frameworks.

Summary:
Currently, in order to retrieve the current screen color temperature
applied to all screen as well other attributes of night color manager,
one has to call nightColorInfo() periodically. This goes against well
established patterns in d-bus world. It is recommended to expose a
bunch of d-bus properties rather than have a method that returns all
relevant properties stored in a JSON object.
The ugliest thing about this patch is that a lot of code is duplicated
to emit the PropertiesChanged signal. Unfortunately, QtDBus doesn't
take care of this and we are left with only two options - either do
weird things with QMetaObject or manually emit the signal. I have
picked the second option since it's more comprehensible and less magic
is going on, but I have to admit that the chosen approach is ugly.
I hope that "Qt 6 will fix it."

Summary:
It's perfectly legitimate to call setWindowSize before a buffer is
attached. This seems to have happen with plasma surfaces that commit
when attaching a shadow, but technically could happen anywhere.
By clamping to the applied surface here, we get the wrong window size
cached and not re-evaluated when a surface is eventually applied. This
leaves us thinking the windowsize is empty but with a massive margin
which actually holds the content.
We want all internal usages of xdgshellclient to use the window geometry
set. Only the wider kwin part needs to care about clamping it to the
surface.
