Summary:
This ensures that the X11 specific events are only read on X11 but not
on Wayland. Also moves quite some X11 specific code out of TabBox.
Test Plan: Compile checked, currently on Wayland, so no way to test.

Summary:
A few areas in TabBox perform casts from Toplevel to Client. By casting
to Client instead of AbstractClient the Wayland windows are excluded.
This change addresses the problem by changing the casts where possible.
The only remaining cast to Client is for shading which is not (yet)
supported for Wayland windows anyway.

Summary:
There is a special mode in TabBox which is the noModifierGrab mode. This
is Alt+Tab active without a modifier being hold. This mode is entered
when being activated through screen edges (either pointer or touch). So
far this was not exposed to QtQuick and thus one could not end the mode
using pointer or touch. It is possible to select another window, but not
to activate it. That required the press of a keyboard key.
This setup is rather unfortunate. By exposing the mode to QtQuick we can
react from QtQuick side to it and invoke already exposed functionality to
select and item and directly activate it - existing left-over from the
Plasma Active window switcher.
Test Plan:
Tested on X11 and Wayland with an adjusted lnf package. It kind
of works, but there are additional issues on both X11 and Wayland.

Summary:
The interaction is changed to trigger the check for release from the
TabBoxInputFilter instead of reacting on modifier changes. That way
it's possible to check for the relevant modifiers getting released
instead of getting all modifiers in. Also this means that the checks
are only performed when relevant.

Summary:
So far TabBox used highlight windows by passing window ids around through
an X property. This doesn't work on Wayland where we don't have window
ids for our TabBox and the Wayland windows.
This change introduces a new Effect::Feature for HighlightWindows which
the HighlightWindowsEffect provides. The EffectsHandlerImpl has a new
method to highlightWindows which it delegates to that effect if it is
loaded by invoking a new performFeature method.
The TabBoxHandler now passes the highlighting to the effects system
instead of updating the x11 property. Thus this works on Wayland and
at the same time improves the X11 side by no longer having to go through
the property protocol.
Test Plan: Verified that Alt+Tab highlights the windows on Wayland correctly.

The TabBox implements methods for those events and performs same
logic as on X11. Click outside of TabBox closes. If the event is on
the TabBox we don't filter the event out and let the internal filter
forward the event.
By using QWindow we can also find the TabBox window on Wayland where
the winId is not really helpful.
This also changes the elevation from Unamanged to Toplevel, so that
it is no longer X11 specific.
Result: TabBox stays on top of all windows also on Wayland.
The change is mostly straight forward. Effects are straight forward
adjusted. Client::findModal is moved up, this causes still a few
dynamic_casts to Client. Mostly because Workspace::activateClient still
operates on Client.
Both were only added for the use case of Plasma Active. In the next
iteration we won't need the embedded any more as Plasma is able to draw
thumbnails by itself. So there is neither need for the embedded
functionality nor for the D-Bus interface.

Forward all key press events to the TabBox if it is currently grabbed and
connect the TabBox to the modifiers changed signal for checking if TabBox
should be ended.
The modalActionSwitch was used to disable all of KWin's actions during
Alt+Tab. This is not needed as Alt+Tab uses a keyboard grab and thus
no action will be triggered anyway.
Furthermore the functionality had been broken for years. The effects
use an own KActionCollection so their actions aren't considered and
neither the scripts.
Client used to have dedicated methods for different icon sizes instead
of combining all pixmaps into one QIcon. This resulted in various parts
of KWin having different access to the icons:
* effects only got one pixmap of size 32x32
* decorations only got the 16x16 and 32x32 pixmaps combined into a QIcon
* tabbox could request all icon sizes, but only as pixmap
Now all sizes are available in one QIcon allowing to easily access the
best fitting icon in a given UI.
All the globalShortcutChanged slots are removed and replaced by a
generic one for the new signal by KGlobalAccel.
The define for creating the shortcut is dropped and replaced by a
templated function creating connections through the new connect
syntax.
Button Press/Release do no longer fall through to motion notify as
there is no shared mouse event in xcb. Also the methods in Effects and
TabBox are adjusted to process only button press/release or motion
notify.
ScreenEdges are no longer checked for button press/release. They don't
interact on button press/release so there is no need to check it.
It's only used from useractions.cpp which means that it's not the best
fit in utils. We can see the problems with it given that it was in an
ifdef and it included quite some headers into everything.

It's an option doing pretty much the same as the highlight of selected
window option. But it is known to conflict especially with some Plasma
themes.

There is only one instance hold by Workspace which means it should follow
the common approach with ::self and ::create.
The hasTabBox is completely removed as it's rather useless and the same
as the ifdef around the usages any way.

The new class FocusChain manages two different kind of focus chains.
First of all there is a most recently used focus chain which is primarily
used for TabBox.
Then there is one focus chain per virtual desktop. These chains are used
to determine which Client needs to be activated when e.g. switching to a
virtual desktop.
The individual chains are implemented as a simple QList of Client* with
the most recently used Client as the last element. That way one can see
it as a LIFO like structure.
The desktop focus chains are internally represented as a hash with the id
of the virtual desktop as the key and a list as described as the value.
FocusChain is a singleton which provides some methods to manipulate the
chains and to get a specific Client for a task (e.g. TabBox).
While splitting out the code some unused code inside TabBox got removed
as well as some activities related code (windows cannot be moved while
switching activities).

Use xcb to create and manage the X11 backend of Outline. In addition the
used background pixmaps are rendered with XRender instead of using a
QPainter on a QPixmap. This is done because QPixmap is no longer bound to
an X Pixmap.
To create the XRender Picture the available functionality from
kwinxrenderutils is used. To be able to use it in KWin core the compile
option to build without XRender is removed for kwinxrenderutils, but
still supported for effects.
Obviously the port to XCB is not complete as xremderutils itself is still
on XLib.
REVIEW: 108642
Most recently used virtual desktop chain is only used in the context of
TabBox and therefore moved into this namespace. KWin uses one desktop
chain for each activity. This is mapped by having multiple DesktopChains.
In addition there is a DesktopChainManager which contains all those
chains which are identified by a QString.
The manager gets connected to the signals emitted by VirtualDesktopManager
for changes in virtual desktops and to signals related to Activities
emitted by Workspace. This means the manager is rather generic as it does
not depend on any other components.
If the start Client is not part of the focus chain the call to
nextClientFocusChain() cannot return the Client again. So the loop break
condition is never reached and as the focus chain is not empty the call
always returns a not null Client which means KWin is caught in an endless
loop.
This change checks that the starting Client is in the focus chain and if
not the first Client of the focus chain is used.

The recently used mode of TabBox uses the active window as the entrance
into the focus chain. If there is no active window it does not find any
Clients. To solve this issue the ClientModel now uses the first entry
of the focus chain in case there is no active window.

Client holds a SharedPointer to the TabBoxClient and only
provides access to a WeakPointer which is passed to TabBox.
ClientModel is adjusted to hold a list of WeakPointers instead
of the direct pointers.
This fixes the following reproducable crash:
1. Configure both primary and secondary TabBox with different
layouts
2. Use primary TabBox
3. Close a window, best the one which used to be active
4. Use secondary TabBox
-> Crash
The reason is that the ClientModel still contains the pointer
to the deleted TabBoxClient in step 3 and while creating the
layout access to the TabBoxClient is needed to get the Client's
icon.
By using the weak pointer it can be ensured that we don't try
to dereference the deleted pointer and prevent the crash.

cppcheck complained about that piece of code and it was not
really good. A TabBoxClient belongs to exactly one Client which
means the setter should for Client should not be there in the
first place and was only used during construction.

If the layout name is specified a custom layout config is

This can be used by Plasma Active to specify the window strip

to opening Present Windows Effect.

DBus method to embedd the TabBox into another window. It follows
