This is Milestone 1 of full support of Atomic Mode Setting (AMS) and
Universal Planes in the KWin DRM backend.
With Milestone 1 we can use the primary plane of a DRM output and do an
AMS commit (this means mode setting aswell as page flipping), if the
driver supports it. Until now the functionality is only tested on Intel
graphics. You need the drm-next kernel for most recent DRM kernel
developments. As boot option set "i915.nuclear_pageflip". Additionally
at the moment AMS is still hidden behind the environment variable
KWIN_DRM_AMS. Set it, if you want to try out AMS.
What needs to be done next: Make it possible to transfer EGL buffers
directly to planes and implement logic for deciding about using a plane
or not for a specific buffer.

This allows finding the Toplevel for a QWindow which is on Wayland a
ShellClient and on X11 an Unmanaged. This can be used to simplify
code when a Toplevel is needed for an internal QWindow without having
to do platform specific checks.
This adds a new test case which maps an OSD window and verifies that it's
positioned correctly. Then an additional screen is added which should not
affect the position, but as the test case shows: it does affect the
position.

Summary:
The Xkb class now creates a compose key table and a state object and
feeds all key presses through the compose state machine.
Xkb now tracks the latest keysym which is provided through new method
currentKeysym. This is now used when creating a QKeyEvent instead of
passing the key code to the xkb state. With that the keysym can also
be updated through the compose state system.
This only affects KWin internal usage where text is composed, e.g. the
present windows effect filter. Wayland clients do not gain compose key
support, though.
Minimum xkbcommon version raised to 0.5 as compose key support is new
in that version.
Test Plan: Enabled compose key support in keymap and verified through DebugConsole

The properties:
* maximizable

in the EffectWindow having those properties evaluate always to false
for a ShellClient and breaking some effects.

Summary:
So far this connect was only in ShellClient, but it's needed for all
Toplevels. Also when a XWayland window has it's surface size changed,
the pixmap needs to be discarded. Otherwise KWin might hit an assert
in AbstractEGLTexture due to the buffer having a different size than
the texture had previously.

Summary:
SharingPlatformContext::swapBuffers needs to make the context current.
For this is calls makeCurrent. Later on this tries to bind a fbo, which
checks calls into the current QOpenGLContext. As we called makeCurrent on
our own platform context Qt doesn't know that the context is current and
returns in the worst case a nullptr and crashes.
This change calls makeCurrent on the QOpenGLContext so that Qt also knows
that this context is current now. The QOpenGLContext calls makeCurrent on
the platform context, so what our code tried to do is still being done.
In addition the method context() in AbstractPlatformContext is renamed to
eglContext to no longer shadow the method in QPlatformContext.

New test infrastructure which supports testing window rules at runtime.

a case insensitive manner.
CCBUG: 367554
Summary:
The raw pointer button events intercepted in the XInput2 input filter
get sent through the Platform to the PointerInputRedirection. This
makes the PointerInputRedirection track the pointer button state and
emit the signals for button changed and axis changed.
These signals are used by the modifier-only shortcut detection to
determine whether the shortcut should trigger.
On X11 the "normal" input handling doesn't use the InputRedirection
and the emitted signals are not consumed by anything else. As
PointerInputRedirection is not inited the events are not forwarded
to the input filter, thus won't be processed by other parts and
won't interfere with the normal event processing on X11.
Given that it also doesn't matter that the input filter does not
apply the left-handed setting. The internal tracking will have a
wrong mouse button, but nothing is going to do decisions based on
the value of the pressed mouse button. For the moment all we are
interested in is that a button is pressed.
Test Plan:
Pressed meta, clicked, scrolled, released meta: launcher
did not open. Pressed meta, released meta: launcher opened

BUG: 367730
Summary:
For Xwayland windows we observed that passing pointer focus to another
window does not trigger proper leave events on X. Which results in e.g.
tooltip windows to show after the pointer moved to a completely
different position on a completely different surface.
This is a bug in Xwayland which will be fixed in 1.19 (already fixed in
master). Given that there is a runtime version check. Although it's fixed
in Xwayland master it's worth to carry a workaround.
To circumvent this problem KWin warps the xcb pointer to 0/0 whever an
X window loses pointer focus. That way the X window gets a proper leave
through the X protocol.
This created a problem though: when giving focus back to the X window it
started to warp the pointer for maximized windows as KWin got pointer
motion events through the X11 event filter for positions on the window
decoration. These are passed into the screen edge filter which pushes
the pointer back and warps our Wayland pointer. To solve this problem
KWin no longer performs any actions for pointer motion in the X11 event
filter if not on X11. The event filter needs to be reworked and most of
it should be moved into the Platform API, if possible.
Test Plan:
Reproduced situations where one could see that pointer updates
don't trigger leave. E.g. going from a highlighted window to the decoration.

Summary:
This allows Client to use the Wayland-specific implementation if there
is no icon geometry set through the X11 way. That way Xwayland windows
have an icon geometry even if Plasma is using Wayland and setting the
icon geometry in the Wayland way. Which is expected as Plasma is
ignorant about the windowing system a PlasmaWindow uses.
In order to move the code from ShellClient to AbstractClient
WaylandServer gained a new findAbstractClient(Surface*) method which
is just like findClient(Surface*) with the difference that it returns
an AbstractClient instead of a ShellClient*.

Summary:
The new logout design doesn't want to have the vignetting. Thus the
logout effect itself doesn't make any sense any more. All that would
still be used is the logout blur which can also be provided by the
blur effect nowadays for fullscreen windows. As the new logout is a
fullscreen window it should use that one.
The logout effect did one more thing: it kept the vignetting and the
blur once the user selected logout. Now without the vignetting this
would be weird and again doesn't make much sense any more.
So overall I think it's better to just drop the logout effect and use
blur effect in normal way. Neat side advantage: it will also work on
Wayland out-of-the-box.

Removes one of the last pure XLib usages and also means that in theory
we can detect the Xwayland version number. In practice that only works
when restarting the compositor as detect is invoked before the XWayland
connection is created.
Summary:
This change introduces a Scripting::findScript method which returns
the AbstractScript. Thus a test can load a script, retrieve it and
trigger run on it. As the test would also need to know when finally
the test is running a signal is introduced to notify about it.
This makes the scripting ScreenEdgeTest way more reliable. The test
had been failing on both build.kde.org and build.neon.kde.org due to
not knowing when the script is loaded.

Just like 4e7392b907:
the ownership of the gbm_device must be passed to the Platform as
the ownership of the EGLDisplay is also passed to the Platform and
we may not destroy the gbm_device for an EGLDisplay we are still using.
With this change I could restart the OpenGL compositor successfully
and switch from OpenGL 3.1 to OpenGL 2 without a crash or rendering
issues.
The Egl backend opens the drm device and creates a gbm_device from it.
From that it creates the EGL device. The EGL device outlives the EGL
backend (e.g. for compositor restart). So far the EGL backend destroyed
the gbm_device when going down which mesa did not like at all when a
new context got created on that EGL device.
Thus the ownership of gbm_device is also passed to the Platform so that
the compositor can be restarted.
This makes the TestSceneOpenGL no longer crash during the restart
compositor test.
This fixes a regression found in TestSceneQPainter for restarting the
Compositor. The internal clients were never added to the Scene.
We cannot just call setupCompositing because there is a phase during
startup where setupCompositing already passes but the Compositor is not
yet fully initialized. Thus it could happen that it's called twice which
makes the Scene assert.
To solve that setupCompositing and finishCompositing are now overriden
in ShellClient and track whether they successfully called
setupCompositing.
At the same time the xinput2 integration is split out of X11Cursor
and made a standalone part of the platform plugin. XInput integration
is nowadays not only used by the cursor position polling, but also
for modifier only shortcuts.
By splitting it out the modifier shortcuts start to work also when
one doesn't have anything requesting a mouse position polling.
This also simplifies the conditional builds: xinput integration is
only included if we have support for it at compile time without having
to have many ifdefs in the cursor implementation. For the inclusion of
cursor in the kcmkwin this also removes all the ifdefs.
The key events are only requested if we have xinput 2.1. Otherwise we
would not get all raw events if the input device gets grabbed.

By default the InputRedirectionCursor is created and only the X11
standalone platform creates the X11 specific cursor.
This is a preparation step for moving the X11 specific cursor
implementation into the x11standalone platform plugin.
Summary:
If caps lock is on the shift key should not trigger. Similar pressing
caps lock should neither on activation press nor on deactivation press
trigger the shortcut. Related to that are latched modifiers aka sticky
modifiers: if the modifier is still on after releasing the key the
shortcut should not trigger. We must assume the user wanted to use the
modifier to activate the modifier, not to activate the shortcut.
This change ensures that we don't track for modifier only shortcuts if
a modifier is active before press or after release.
The added test case demonstrates for caps lock, latched modifiers is
currently still untested. (Needs a way to mock it).
Test Plan: See test case for caps lock.

We should be able to restart the Compositor also on Wayland.
As the Compositor might be terminated after Workspace we need to
ensure to not call into Workspace while doing finishCompositing.
Reviewed-By: bshah
For the exit-with-session option in kwin_wayland there is a chance that
the window which triggered termination is currently a Deleted. The
Wayland shutdown sequence terminates Workspace before the Compositor
which results in that Deleted's Scene::Window surviving the shutdown
process and thus the Shadow not being removed from the cache. This
makes KWin assert very late in the shutdown process when the decoration
shadow cache gets destroyed.
Summary:
So far when deleting a Shadow we used deleteLater which caused it
to be deleted in the next event cycle. This could in worst case result
in the Shadow being deleted after compositing got suspended. Thus the
Shadow not getting removed from the DecorationShadowCache which in
turn would mess up rendering on resume of compositing as the cache
returns a texture created for a different context.

Summary:
The new effect is based on the mouse click effect and uses the same
rendering code (this could be improved by merging them better).
Unlike mouse click there is no keyboard shortcut needed to activate:
as soon as the effect is loaded all touch points are visualized.
The visualization creates an animated circle for each touch down
position, motion and up position. The ids are tracked and each touch
id gets the same color. The first ten different touch ids get a
different color. As touch ids are stable the first finger will always
have the same color.

Summary:
KKeyServer does an incorrect translation to keysyms: it always
translates to the uppercase variant.
This change makes the default go through xkbcommon and tries to get
the keysym from matching the unicode representation. E.g. an "a" is
then recognized as the lower case a, and an "A" as the uppercase one.
Only if the translation through text fails we pass back to KKeyServer
which does a reasonable translation for non-text symbols.

The Xkb class loads keyboard layouts from the users configuration. This
makes tests fail locally if the user has a layout which behaves
differently to the one the test expects. E.g. on a German layout the
right alt key is different to the one of US layout.
In order to have a more stable test base the env variable
KWIN_XKB_DEFAULT_KEYMAP forces the loading of the default keymap, thus
tests have a common layout set.

Summary:
Now powerdevil can adjust brightness using leds subsystem, however, kwin
as well sets brightness to 0 for turning off screen and 0xff when
turning screen back on. This resets the brightness set by the powerdevil
to 100%.
As a solution now kwin listens to brightnessChanged dbus signal of
brightnesscontrol and book-keeps the changed brightness, if screen is
turned off it sets brightness to 0 and when turning screen on, it resets
to old brightness.
If powermanagement service doesn't appear on dbus by default it restores
100% brightness.
Test Plan:
Appearantly this still doesn't work as-it-is on phone, because powerdevil
doesn't emit brightnessChanged dbus signal because of bug in the driver of
backlight control, driver doesn't seem to trigger uevents for changes in
backlight. But with hack in powerdevil to emit brightnessChanged when setting
brightness, this works

Creating a dedicated method for the leave event on client.
This restructuring of the test should hopefully work around the
failing test condition on build.kde.org.
Summary:
The Effect class is extended by three new virtual methods:
* touchDown
* touchMotion
* touchUp
The methods return a boolean value so that the events can be filtered
out. E.g. an effect which has also a mouse grab installed wants to
filter out all events, other effects don't need the events exclusively.
This is a difference to how e.g. keyboard and pointer events are handled.
But is more close to how KWin's internal input event passing works and
makes it easier to get touch event: one does not explicitly has to grab
the events. It's also closer to Wayland where all input events are
available.
As a first example the Present Windows effect is adjusted and allows to
activate windows through the touch screen. As much code as possible is
shared with pointer input.
