Summary:
Despite plasma frameworks doing it's own scaling with fonts, it's been
requested to use kwin/wayland scaling.
Like DRM, when kscreen is not used, scale value is loaded from a config
file.
Config format is
[HWComposerOutputs][0]
Scale=N
The 0 is to map similarly to DRM and support multi-screen, but with a
screen index
rather than a UUID based on EDID.
Because we don't support multi screen this is always 0 for now.
Test Plan: Ran with the config value unset and with the config value at
Scale=3.

Summary:
Adds an autotest to show that KWin fails an assertion when a client tries to
resize a sub-surface.
Since it is the first autotest dealing with sub-surfaces explicitly additional
autotest helpers are introduced to allow that.
We also add a new signal in Compositor to spy on to know when the buffer swap
has been completed.
Test Plan:
Test fails as expected:

Summary:
Most of the functionality which is special to internal clients is moved
from ShellClient to InternalClient. As KWin's qpa is still bound to the
Wayland protocol InternalClient inherits from ShellClient. Due to that
some aspects in ShellClient are "weird". ShellClient still detects
whether it's an internal client and uses the variable m_internal to
capture the state. This is required as we cannot use the isInternal
method. Most of m_internal usage is in init which is called from
constructor of ShellClient. Thus it's not possible to call into virtual
methods of InternalClient.
Also some of the code is duplicated and some methods are temporarily
marked as virtual.
The next step will be to remove ShmBuffer for internal windows which
should decouple the two implementations further with the long term goal
of having InternalClient inherit AbstractClient directly.
Test Plan:
Run nested KWin, triggered outline (OpenGL case) and debug console (shm case).
InternalWindow unit test still passes.

Summary:
Currently, KWin/Wayland crashes when the compositor is reinitialized.
The reason for that is ShellClient's DecorationRenderer gets destroyed
when the scene is already gone, thus there is no current OpenGL context.
Client works around that issue by destroying scene-specific DecorationRender
in finishCompositing. Such a workaround could be applied to ShellClient
as well, but it would make code more confusing because DecoratedClientImpl
also tries to destroy DecorationRenderer.
A better approach would be to notify DecoratedClientImpl that
compositing is about to be finished, so it can destroy the decoration
renderer when the scene is still alive. This not only fixes the
previously mentioned issue in ShellClient, but also makes code a little
bit tidier.
Test Plan:
Start Plasma on Wayland session, change any compositor settings (e.g.
animation speed).

Summary:
Some X clients acting as drag sources might try to optimize finding the current
target window by checking if a window manager, that sets the root window
_NET_CLIENT_LIST_STACKING property, is present. An example for this is Chromium
and since KWin sets the property the drag proxy windows must be added to this
list. Otherwise the origin client will not detect the proxy window and not send
an XdndEnter message.
Test Plan: Manually with Chromium.

Summary:
On X several target atoms are established to provide data similar to the
text/uri-list target format (the respective MIME on Wayland is called
text/x-uri).
Firefox can send link data in the NETSCAPE_URL format ones. Chromium on the
other side sends link data in the text/x-moz-url format, which transports
UTF-16 text.
For both these peculiarities this patch provides converter functions, that
translate these formats into the Wayland native text/x-uri format. In the
other direction no translation is necessary. Both browsers supports the
text/uri-list format when receiving link lists.
Test Plan: Manually with Firefox and Chromium.

Summary:
Building upon the generic X Selection support this patch establishes another
selection class representing the XDND selection and provides interfaces
to communicate drags originating from Xwayland windows to the Wayland
server KWin and drags originating from Wayland native drags to Xwayland.
For Wayland native drags KWin will claim the XDND selection as owner and
will simply translate all relevant events to the XDND protocol and receive
alike messages by X clients.
When an X client claims the XDND selection KWin is notified via the X protocol
and it decides if it allows the X drag to transcend into the Wayland protocol.
If this is the case the mouse position is tracked and on entering a Wayland
native window a proxy X Window is mapped to the top of the window stack. This
proxy window acts as a drag destination for the drag origin window and again
X messages will be translated into respective Wayland protocol calls. If the
cursor leaves the Wayland window geometry before a drop is registered, the
proxy window is unmapped, what triggers a subsequent drag leave event.
In both directions the necessary core integration is minimal. There is a single
call to be done in the drag and drop event filter through the Xwayland
interface class.
From my tests this patch facilitates drags between any Qt/KDE apps. What needs
extra care are the browsers, which use target formats, that are not directly
compatible with the Wayland protocol's MIME representation. For Chromium an
additional integration step must be done in order to provide it with a net
window stack containing the proxy window.
Test Plan: Manually. Auto tests planned.

Summary:
In this patch an infrastructure is created to represent generic X selections
in a Wayland session and use them for data transfers between Xwayland windows
and Wayland native clients.
The central manager is the DataBridge class, in which Selection objects can be
created. This is hard-coded and such a Selection object persists until the end
of the session, so no arbitrary selections can be created on the fly. For now
the X Clipboard selection is supported, whose corresponding mechanism in the
Wayland protocol is just called Selection.
A Selection object listens for selection owner changes on the X side and for
similar events into the Wayland server interfaces. If a data provider is
available a selection source object is created by the Selection object. In case
data is requested on the other side, a data transfer is initialized by creating
a Transfer object. A Selection keeps track of all transfers and makes sure that
they are destroyed when they are finished or in case they idle because of
misbehaving clients.
The Clipboard class translates the X Clipboard via a proxy window. Selection
changes on the Wayland side are listened to through a new signal on the active
KWayland seat interface.
The previously used X clipboard syncer helper is disabled. The clipboard sync
autotest is changed to the new mechanism.

The Xwayland code path is moved from ApplicationWayland to a dedicated class

This is a direct preparation step for generic support of Xwayland Selections.
On a longer timescale this should also allow us to further separate Wayland
native functionality from Xwayland to allow us at one point to build KWin's
Wayland binary optionally without X dependencies. Another long term goal, that
becomes possible through this separation is to recover from Xwayland crashes.
