We can see that especially detecting modern radeon gpus is not working.
Summary:
With this change KWin can create window decorations for internal windows.
Thus it's also possible to move internal windows and resize them which is
especially important for the debug console.

So far KWin's pointer surface enter handling was:
1. update fouced surface
2. update the global position
On client side this resulted in:
1. Enter with incorrect coordinates
2. move event to correct coordinate
With QtWayland this results in the case of multiple surfaces in one
application that Qt doesn't properly process the enter event and the
Window never getting pointer focus and not reacting on any pointer
input events.
The root problem is that the KWayland server API is not ideal for
supporting this situation. There is an API call for setting the global
position (which causes a pointer motion for the focused surface) and
an API call to update the focused surface. But a combination for both
is (still) missing.
This change addresses the problem by first unsetting the entered surface,
then updating the global position and afterwards setting the new surface.
Thus the position is correct. While this needs to be made better in
KWayland, this is an urgency bug fix to get the behavior correct and thus
first working around the API deficit and not first extending in KWayland.

Summary:
When closing a nested window kwin_wayland only terminates if the closed
window is the last output window. In a simulated multi-screen setup
closing a window results in the output being removed.

Summary:
Gesture events are swipe or pinch events on a touch pad.
This change implements basic support by:
* wrapping them in LibInput::Event
* processing them in LibInput::Connection and emitting
dedicated signals
* Forwarding them in InputRedirection to PointerInputRedirection
* Support them in the internal input event filter
* Printing debug information in DebugConsole
Further handling is not yet done. In future the following should be
implemented:
* activating e.g. zoom and present windows on pinch/swipe gesture
* forwarding non global gestures to KWayland
Note that forwarding to KWayland is not yet useful as QtWayland does
not yet have support for the unstable protocol. No Qt application could
make use of it yet. So for the moment just global gestures is the best
we can get.
Test Plan: Looked at output of DebugConsole when triggering gestures

Screens::init sets up a Qt::QueuedConnection connect from countChanged
to changed. This means that when first setting up the connection a
changed signal will be delivered in the next event cycle. This can mess
with other code. E.g. WaylandServer recreating outputs which can make
Xwayland crash or KWin internally crash.
To solve this problem we just need to make sure to set the output count
to the initial value before performing the init.

The new test can load "profiles" from kconfig files in the test data.
Based on that the glGetString return values are mocked and GLPlatform
can perform detect without having to interact with a real GL library.
That way we can verify that the detect code works correctly. As a first
test the settings of one Intel/IvyBridge is included. More tests can be
added easily (e.g. looking at various supportInformation output in
bugs.kde.org). Also this allows to more easily add detect code for GPUs
we do not know yet. And to simulate conditions where the detect code
failed resulting in no compositing at all.
Summary:
Rational: unredirect fullscreen windows is a weird beast. It's intended
to make fullscreen windows "faster" by not compositing that screen. But
that doesn't really work as KWin jumps out of that condition pretty
quickly. E.g. whenever a tooltip window is shown. KWin itself has a
better functionality by supporting to block compositing completely.
The complete code was full of hacks around it to try to ensure that
things don't break.
Overall unredirect fullscreen has always been the odd one. We had it
because a compositor needs to have it, but it never got truly integrated.
E.g. effects don't interact with it properly so that some things randomly
work, others don't. Will it trigger the screenedge, probably yes, but
will it show the highlight: properly no.
By removing the functionality we finally acknowledge that this mode is
not maintained and has not been maintained for years and that we do not
intend to support it better in future. Over the years we tried to make
it more and more hidden: it's disabled for Intel GPUs, because it used
to crash KWin. It's marked as an "expert" option, etc.
It's clearly something we tried to hide from the user that it exists.
For Wayland the whole unredirect infrastructure doesn't make sense
either. There is no such thing as "unredirecting". We might make use
of passing buffers directly to the underlying stack, but that will be
done automatically when we know it can be done, not by some magic is
this a window of specific size.
Test Plan:
Compiles, cannot really test as I am an Intel user who never
had that working.

If the event processing is started before everything is fully started
it can happen that we have "evil" events which may crash either Xwayland
or KWin itself. E.g. if the nested window is too large, the window
manager on the host X-Server will request a resize. If the backend does
that it can happen that the wl_output gets destroyed while Xwayland tries
to bind to it and will crash. Thus let's delay all events till we are
ready to process them.
Summary:
This fixes a regression introduced with a1afeded6a.
The connections were setup every the windowShown signal got emitted.
This caused effects to get multiple singals and start multiple animations
which then do not get cancelled correctly.
The incorrect behavior was most visible in the translucency effect which
did not cancel the move animation and the window stayed translucent.
BUG: 366081
Test Plan:
New test case which simulates the behavior of the translucency
effect.

Summary:
This is a workaround for QTBUG-54371 resulting in QtWayland never
requesting the input methods panel without having keyboard focus.
Thus also the virtual keyboard is not working.
With this change we go back to always announcing a keyboard and
binding the virtual keyboard to whether we don't have an alpha-numeric
keyboard instead of whether there is a keyboard on the seat.

The capability tablet tool is new in Libinput 1.2. As build.kde.org
does not yet support this version, it's only an optional check.
So far the code only detects whether the capability exists and reports
this accordingly.
A new sub-directory scripting is added in autotests/integration to
gather all test cases related to scripting.
The first added test case verifies the activation of screen edges. For
that it loads a helper script, which reserves an edge based on config.
When the edge is triggered showing desktop is activated.
Summary:
The egl implementation for the virtual platform tries to use a render
node if available. If there is no render node it looks for a virtual
(kernel driver vgem) device, which unfortunately does not create a
render node in mainline kernel (there are patches in ChromiumOS).
For this the Udev wrapper is extended to search for renderNode devices
and for virtual dri devices.
If either render node or vgem dri device is found, it is tried to be
opened (without logind escalation) and on success a gbm device is
created on it. If any step of this fails the so far default behavior
of default device is tried for creating the EGLDisplay.
All of this is compile optional, so that the virtual platform does not
hard depend on udev and/or gbm.
Test Plan:
Auto tests which need OpenGL executed and verified that they
use the render node or vgem device.

Summary:
So far SharingPlatformContext was only used if the OpenGL context
supports EGL_KHR_surfaceless_context. If not supported, KWin tried to
create a context through the Wayland API. Unfortunately on hwcomposer
platform this results in a crash as libhybris only supports the init
of EGLDisplay for one native platform.
This change tries to also use the SharingPlatformContext if there is
an OpenGL context in general. It reuses the native EGLSurface created
for the compositing scene and makes its own OpenGL context current on
that surface, too. As KWin creates an FBO, it never renders to it, so
it shouldn't matter at all.
In order to prevent EGL_BAD_MATCH errors when making Qt's OpenGL context
current also the EGLConfig from the scene is used to create the context.

Summary:
KWin needs to support restarting the OpenGL compositor in case of a
graphics reset event.
On Wayland the tricky part is that the applications should not notice
this. Most importantly KWin cannot just destroy the EGLDisplay and create
a new one. But this is how a restart works: the complete compositor gets
torn down and recreated - including the EGLDisplay.
This change moves ownership of the EGLDisplay to the Platform.
The AbstractEglBackend subclasses query the Platform whether there is
already an EGLDisplay. Only if there is no EGLDisplay the EGLDisplay is
created and only if no EGLDisplay is registered with Wayland the bind
is performed.
Another change is regarding the destruction: the AbstractEglDisplay does
no longer unbind the Wayland display and does no longer destroy the
EGLDisplay. The EGLDisplay is destroyed by the Platform - so very late
on application exit. The Wayland display is unbound when the Compositor
terminates.
Test Plan:
Limited testing with the added auto-test. This one needs to
be extended to fully verify that OpenGL applications continue to work.
But this requires build.kde.org to support OpenGL on Wayland.

Summary:
Most platforms like the nested and virtual do not handle the outputs
themselves and WaylandServer announces the Outputs to Wayland.
So far this was static: at startup it got announced once to Wayland
and any changes were not catched.
This change makes WaylandServer listen to changes to the Screens and
sync them to Wayland.
Unfortunately KWin's internal Screen information is not sufficient to
properly synchronize this to Wayland and also Wayland by not supporting
adding/removing modes does not help.
Thus the solution implemented here is to add new outputs reflecting the
changes and then removing the old ones. This creates situations with more
outputs being present than actually there, but prevents that there are
no outputs at all.

Summary:
The selection of whether GLX or EGL should be used doesn't work in
practice due to the following reasons:
* Intel/EGL/X11 results in rendering errors
* NVIDIA still doesn't support EGL
* OpenGLES forces to EGL (combobox only one entry)
* Wayland forces to EGL (combobox only one entry)
Offering the selection only offers the user a way to destroy the
system. We get too many bug reports about rendering errors and we
get too many complaints about this not working properly on social
media. E.g.: "The Meh: EGL mode causes bugs in the launcher"
The configuration interface showed a warning when selecting it, but
apparently users ignore warnings like "might be broken". If that's the
case let's better remove the option.
If users really want this they can still enable it manually through
editing the config file or through the env variable.
Change intended for Plasma/5.7 branch - I'm sick of users complaining
about it!
