Summary:
On Wayland we have the sync disabled as it doesn't work properly. This
allows us to also move the sync event handling into the X11 standalone
platform.
The code is slightly refactored: instead of passing the event to each
Client, we search for the matching Client. For that the SyncAlaram struct
is added to public section of Client. The method to handle the sync
doesn't need the event any more and is moved from events.cpp to
client.cpp.
Test Plan:
Run Xephyr+kwin_x11, resized a window and verified through
gdb breakpoint that the sync still works

Summary:
So far both Workspace and Toplevel emitted signals for every property
notify event on the root window and the respective Toplevel windows. The
signals were only used in EffectsHandlerImpl to forward to the effect
system in case the property which changed is registered by an effect.
This change introduces a dedicated event filter for this which is only
created in EffectsHandlerImpl in case an X11 connection is available. It
supports a restart of the X11 system.
The signals used so far are removed from Workspace and Toplevel.

Summary:
This change introduces a dedicated X11EventFilter for the mouse
interception on X11. The filter gets created together with the start
of mouse interception and destroyed again when the mouse interception
ends. Thus we don't need to check for each event like it was the case
so far.
Unfortunately the existing methods cannot be removed (yet) as they are
still used by TabBox. Needs investigation whether this is actually
needed.

Summary:
The code in events.cpp was problematic as it was called in a Wayland
session. So KWin changed outputs, this gets mirrored to XWayland and
then KWin reacted on the XRandR event and might have even changed the
refresh rate due to that - bad idea.
This change moves the code into the already existing X11EventFilter for
XRandR events in XRandRScreens.
Test Plan: Run kwin_x11 in gdb on Xephyr, breakpoint in new code and triggered XRandR event

This change splits out the X11 specific event filtering into a dedicated
X11EventFilter. It is created in the x11 standalone platform plugin when
the first Edge is being created.
Some of the X11 specific code is removed from ScreenEdges, though more
refactoring is possible in ScreenEdges to share more code between X11
specific and generic implementation.

Summary:
I don't know what the idea of entering QWhatsThis mode was, but the code
is pretty much dead. There is no QWhatsThis window shown as KWin does
not have any UI or help. The window which eventually gets shown in
context help is provided by the client application.
Furthermore KWin never leaves the QWhatsThis mode. At least one code
path entering in leave is dead in general and one at least on Wayland
(but probably also on X11 as the window never gets shown).
The show context help functionality works fine without the QWhatsThis
handling, so let's remove it.
I tried to blame what was the idea behind it, but it was unchanged since
decades and blame ended in a code moving commit.
Test Plan: Used show context help (kcmshell5 --platform xcb kwinoptions)

Summary:
Workspace monitors the X11 events to detect when the user first
interacts with the system. This is only required on X11 for activating
the same client from previous session. So far this was spread over many
parts in the long event switch statement. To make this more contained a
dedicated event filter is introduced which also gets deleted again once
the first user interaction got recognized.

Summary:
So far the X11EventFilter only supported one event type. But most
usecases for an X11EventFilter require to support multiple event types.
E.g. a filter listens for both key press and key release.
This change extends the internal X11EventFilter to support multiple
types and Workspace::workspaceEvent makes use of that.

Summary:
KWindowSystem provides a KDE specific property for the desktop file
name. This allows KWin to take the icon from the desktop file. The
advantage from the desktop file is that KWin normally gets higher
resolution icons than provided through the xproperty based icons used
previously. If the desktop file does not provide an icon name, KWin
falls back to the previous implementation.
As on Wayland the icon is taken from the desktop file name already the
code for X11 and Wayland is merged in AbstractClient. Also to the
PlasmaWindowInterface the appId is taken from the new desktop file
instead of the resourceName. Due to that for Xwayland windows where KWin
knows the desktop file name it can be passed to PlasmaWindowInterface.
This allows e.g. the task manager to better map the windows to
applications and provide better icons. Also it means that icons do not
need to be passed as bitmap data to the clients.
Test Plan:
Verified that icon is taking from desktop file if provided and
from X property if not provided and that Wayland windows still have icon.

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:
The mouse polling is also used to detect mouse button press/release
events. This is used e.g. by the MouseClickEffect. The XInput2 filter
only selected for Raw Motion events which means mouse button events
are missed in case it's not combined with a motion.
This change makes the input filter also select for raw button press
and release events. To support this the X11EventFilter needed to
be adjusted to support multiple generic event types to filter for.

Summary:
For an X11 window through Xwayland KWin gets a client message with the
Surface id. KWin has two code paths for handling that:
* Wayland Surface is created after the X11 event
* Wayland Surface is created before the X11 event
In the first code path in WaylandServer KWin called Toplevel::setSurface,
the other code path just updated the m_surface without calling into
setSurface. This means the connects for the Surface were not set up,
resulting in the worst case in accessing deleted memory after the Surface
was destroyed.
This change now ensures that setSurface is called from both code paths.
That should fix the potential crash and could also be a fix to the
problem that sometimes X windows seem to not be damaged correctly.

Mouse actions like wheel and double click were restricted to the titleBar
area. This made the top most pixel non-interactive as it's not part of the

This change makes the complete titlebarPosition interactive. That is it
includes for a "normal" (top) setup also the TopLeft/Top/Right section.
Thus the top most pixel can be double clicked, mouse wheeled, etc.
For the Wayland case the test case is adjusted.

Summary:
The cursor position is the reference KWin uses while moving a window.
If we don't warp the cursor position the window "jumps" to the cursor
position on first movement.
For requests triggered by the client (e.g. widget style) this does not
matter as the cursor is at the correct position. But for tools such as
task bars we should ensure the cursor is at the right pos.

General handling for mouse driven focus and auto raise should and can
be shared between Client and ShellClient. Thus the code is moved to
AbstractClient and invoked from Client::enterNotifyEvent.
This includes the methods:
* decoration()
* decoration() const
* isDecorated() const
In addition new protected methods are added to destroy the Decoration
and to set it.
Usage of m_decoration in Client code is adjusted.
it seems we can "loose" focus reversions when the closing client hold a grab
(eg. the screenlocker or some games) thus we catch the typical pattern

Properly handle the mouse press/release events in InputRedirection
while we move windows. If it's the last mouse release event we end
the move resize of the window. For that we reuse the code written
in Client.
Implementation is moved to abstract_client.cpp as so far events.cpp
does not have any code from AbstractClient.
This includes moving the electricMaximizingDelay from Client to
AbstractClient.
Workaround, this *seems* a Qt problem.
The grab fails while the button is down - Qt then also seems
to release the keyboard.
Not sending it to the deco didn't help either - nevertheless it seems
(from the Qt code) as if the button is currently grabbed
(the code is a dumb forward to xcb_grab_pointer)
As a workaround, the patch simply ensures a grab on releasing a button when
the popup is visible.

The creation of PlasmaWindowInterface is moved from WaylandServer into
AbstractClient. This allows the sub classes to better control when to
create/destroy the Client.
For creation it's bound to becoming visible - that is Windows which are
only created but never shown are not announced at all.
For Client it's destroyed with the normal tear-down of a Client, for
ShellClient it's destroyed on unmapped (which also means a new one
will be created again in case of another mapping of the surface).
As a side effect, this works around the problem that ShellClients do not
yet get destroyed for QtWayland's menus (needs further investigation).
