Summary:
So far the window geometry from xdg-shell wasn't implemented as it should
be. A toplevel must have two geometries assigned to it - frame and buffer.
The frame geometry describes bounds of the client excluding server-side
and client-side drop-shadows. The buffer geometry specifies rectangle on
the screen occupied by the main surface.
State and geometry handling in XdgShellClient is still a bit broken. This
change doesn't intend to fix that, it must be done in another patch asap.
Test Plan: New tests pass.

In case of a failed atomic commit the previous mode should be fallen back to.
For orientation provide again a setter that DRM backend can use to set the
transform back to the last working one.

Summary:
We use internally Qt:ScreenOrientation for representing output transforms.
This is not ideal since the values do not map directly to Wayland transform
values, but we can make it work by using OR combinations of
Qt:ScreenOrientations.
Do this for now and see if we should not better introduce an internal enum
mapped directly.
Additionally the OR combinations need to be handled in the drm backend at
various places accordingly as well (see TODOs).
Test Plan: Compiles

Summary:
Move the Wayland output device and output transform calls from DRM backend
to AbstractWaylandOutput. This leaves still some loose ends that need to be
tied up later. On failed commit we want to fall back to last working state
and orientation getter in general needs some more refactoring.

Summary:
this makes the "no borders" option do something: however it cause many
other issues with many themes that weren't really designed for "no
borders"
it fixes the "tiny borders" for almost all themes, as the whole calculation before
was
completely wrong
Test Plan:
Some themes work way better now, some look broken with no border or no side borders
some look perfect with those options
another issue is that aurorae is going to support no borders, it has to support like
breeze resizing from the shadows

Summary:
If an effect renders a window into an offscreen texture, it's very important
that the window ends up in the offscreen render target rather than the default
framebuffer object. However, that might be not the case if the OpenGL
decoration renderer needs to create a texture atlas since the renderer calls
GLTexture::clear() method, which might clobber the current GL_DRAW_FRAMEBUFFER
binding.

Original code (copied from Aurorae) created a QMouseEvent for

It's safer to have an explicit type check given we come from a downcast
QEvent* and then build the correct event.

Summary:
Removes a tonne of complex code, means any future improvements to our
QtQuick integration only need to be in one place.
QML logic remains in Aurorae as it does complex things. All other
aurorae specialties remain.
Only functional difference is that we now use a shared GL context
between window frames, which Plasma::FrameSVG will make use of.

Summary:
Compositing in X11 was done time shifted, meaning that we paint first, then
wait one vblank interval length and present on prepareRenderingFrame the
previous paint result. This is supposed to make sure we don't miss the vblank
and in case of block till retrace be able to continue issuing commands and
only shortly before next vblank present.
This is counter-intuitiv, not how we do it on Wayland or even on MESA with X.
The reason seems to be that the GLX backend was in the beginning written
against Nvidia proprietary driver which needed this but nowadays even this
driver defaults to non-blocking behavior on buffer swap.
Therefore remove this legacy anomaly fully and directly present after paint.
We then wait one refresh cycle and in the future can optimize this by delaying
the paint and present till shortly before vsync.
Test Plan: kwin_x11 tested on i915 and Nvidia proprietary driver.

Summary:
Selecting not to vsync does not make sense for an X11 compositor. In the end
we want clients to be able to present async if they want to but the compositor
is supposed to send swaps with vsync to the XServer in order to not generate
tearing artifacts.
There was also a detection logic which did some questionable things in case
vsync was not available. I don't think this is necessary at all since we can
just always run a timer to present with or without vsync.

Summary:
It is not clear what the advantage of triple buffering is for KWin. An X11
compositor is meant to swap buffers once every monitor cycle. For that triple
buffering is not necessary.
The functionality is not maintained, does not reliably work as displayed by
the existence of an environment variable to force some behavior, pollutes
our code and every compositing-related problem that might be mitigated with
triple buffering should find a simpler and more fitting solution with other
means.
There is one caveat which is if we shall block for retrace. We set it
currently according to the result of the swap profiler and in the most common
case with double buffering it is set to true. But on Nvidia systems this might
be actual the wrong behavior. Instead of trying to work around this ignore
the issue for now and move the overall architecture to something less complex
by presenting after paint how we do it in the Wayland DRM backend and with
double buffering on GLX (although this is at the moment also borken because
we actually present then twice).
Test Plan: kwin_x11 tested on i915.

Summary:
We have a sha check rather than just readlink as an app in a mount
namespace could have an executable with the same path as an exectuable
on the host system that we trust.
This became overly complicated to solve an issue that didn't exist.
sha(/proc/PID/exe) does resolve to what is currently running even if
sha(readlink(/proc/PID/exe) does not as /proc is magic.
This patch compares the root file system as kwin sees it to the running
exe.
