The way it was implemented it allowed an X11 unmanaged window to become
a key logger. Basically as soon as there was an unmanaged window it got
all key events. This problem was discovered through the xembed-sni-proxy
which broke key input to all Wayland windows in a Plasma/Wayland session.
With this change Unmanaged windows don't get any key events at all. This
might break some applications as e.g. context menus are using override
redirect windows. A test with Qt applications shows that the menus are
still functional and the events are delivered correctly internally.
If applications show problems with this change, we might need to weaken
the restriction.
For the functions from GL_FOO_robustness we want to resolve it by
ourselves in order to add a custom implementation if it's not available.
Unfortunately once epoxy.h is included this breaks as epoxy defines the
names and so through the preprocessor epoxy always wins.
So we need different names: all functions from robustness get a "kwin"
prefix and the usage is changed everywhere in kwin source code.

We need to destroy the ClientConnections we create. Also we need
to disconnect our Xwayland error handling before destroying it, otherwise
it would trigger the abort for crashing Xwayland.
During Compositor tear down Xwayland is already destroyed. Thus it
doesn't make sense to try to delete the support properties: either
it freezes in xcb or it crashes because the connection is null.
At the same time we also ensure that the connection internally is
reset to null. Note: the one in kwinglobals.h caches and could cause
use-after-free errors. Any tear-down code must be migrated to
kwinApp()->x11Connection().
ASAN righly complained: we need to delete our Wayland objects before
we destroy the internal client connection. Solved by better setting
parent relationships in the QPA plugin and correctly delete objects
in destroy of internal client connection.
We need to destroy the compositor after Xwayland terminated and after
the internal Wayland connection is destroyed. This means when destroying
the Workspace we may no longer destroy the Compositor at the same time.
Also we need to ensure that other tear down functionality doesn't call
into the no longer existing internal client connection.
With this change kwin doesn't crash when exiting with Wayland and/or
X11 windows still open.
This allows to check if specific ShellClient is from LockScreen or not,
as well as this adds method to verify if ShellClient is from input
method like maliit.
Now that KWin knows about which window is from Screenlocker it can apply
various security restrictions like no other window then greeter is on
top of it.

Begin of proper multiscreen support!
We load configuration sets for the connected outputs. Each set of
screens represents a unique configuration. For that we use the md5
sum of the edid+connector as uuid of an output. Each of the md5 sums
is then used to create a uuid of the output set. We can be quite certain
that this will generate unique ids for the use cases we will face.
The uuids are used as group names. And from there we read the global
position.
The uuids are considered internal information. It is not intended for
users to configure manually in the config file. The intended way to
configure will be the OutputManagementInterface which recently got added
to KWayland. Once KWin applies a configuration it will store it to config
so that it can be loaded on next startup.
The configuration looks like:
[DrmOutputs][abcdef0123][0123abcdef]
Position=0,0
[DrmOutputs][abcdef0123][fbca3bcdef]
Position=1280,0
This is an example for two outputs set next to each other.

Basically a simplified fork from kwayland-integration.
We cannot use the idletime plugin from kwayland-integration as it
a) doesn't react on our own qpa plugin name
b) performs blocking roundtrips in the main thread -> freeze
This simplifies by using our internal registry and we don't even check
whether Seat and Idle are announced: we know they are.

This introduces --lockscreen option in kwin_wayland which when used will
lock screen immediately. Also dependency to newly created kscreenlocker
repo is introduced.

make the minimize effect work by reading taskGeometry
from plasmawindowmanagement and returning as iconGeometry()
there is one task geometry per panel window, iconGeometry()
will return the geometry associated to the nearest panel
from the window

We only need to force QT_QPA_PLATFORM to be our own plugin when starting
the application. As KWin starts other processes (e.g. kcmshell5) we need
to ensure that the env variable has a sane value. No other process can
load our QPA plugin after all.

The Connection thread fills the event queue, it gets read from the
main thread. In order to properly support the threaded approach the
setup is changed to delegate into the own thread.
When the Connection is created we move it into a dedicated thread
so that even processing happens in the thread. Currently all events
are still queued directly.
Compile failure on KDE CI:
error: ‘GL_GUILTY_CONTEXT_RESET’ was not declared in this scope
It's not defined in libepoxy 1.2, so let's define it to the values
it has in 1.3.
As we don't have GLPLatform before the backend is fully created
the AbstractEglBackend has a new method isOpenGLES() -> bool
which determines based on QOpenGLContext::openGLModuleType().
So far it was bound to whether we build for GLES. But this is
semantically wrong. It might be possible that even on desktop gl
epoxy is built without GLX support, thus we need to reflect this.
This change ensures that epoxy/glx.h is only included if available,
that relevant code is bound to it and that checks are in place to
enforce EGL if not build with glx support.
In addtion the glxbackend.cpp is now only included in the build set
if available.
Only those which truly are different are kept as compile time checks.
In addition the index buffer is made available to GLES as in principle
all required functionality is available on gles.
