Summary:
Everything on the wl_surface is double buffered.
When we create an XdgShell toplevel or popup we shouldn't treat it as
attached until it's committed to the surface.
A client should commit the surface after it's sent it's initial state of
the Xdg topLevel; minimumSize, title, app_id, etc.
By blocking sending configure events we will have flushed the correct
initial state before sending a single atomic correct event to the
client. It also adds a hook to re-evaluate rules now that all properties
are set.
Arguably this applies to WlShellSurface too, but I've left it unchanged
as it's deprecated and hard to verify real client behaviour.

Summary:
Currently, each frame callback sent by KWin has the current time in
nanoseconds, but the protocol spec states that we have to send the time
in milliseconds. This is the reason why animations that are driven by
frame callbacks are too fast.
In addition to that, m_timeSinceStart isn't actually "time since start,"
it's rather accumulated duration of all painting cycles. If there is
something to draw and it takes quite a while to compose the scene, maybe
m_timeSinceStart will be close enough to the current time. So, it has
been replaced with QElapsedTimer, this makes the current time correct
and also simplifies code a little bit.

Summary:
In a recent patch the newly added xwayland class ended up being
responsible for continuing the startup, calling back into the main app
to spawn the workspace.
It moves the flow of startup about so it's not very readable or
following class structure.
This patch moves the code back into main_wayland and removes the
duplication between xwayland and non-xwayland modes.
There was also a misnaming of methods.
Previously:
continueStartupWithScreens was called after platform screens are created
continueStartupWithScene was called after the scene was created
continueStartupWithXwayland was called before xwayland is created
This was confusing, so the names have been shuffled around to follow a
consistent pattern of what has been done so far.

Summary: When creating a surface and setting it as fullscreen before
attaching its buffer KWin does not know the original dimensions of the
surface and tries to use an invalid value when unsetting the fullscreen
flag. This patch fixes this by sending a configure with the size of 0,0
- which according to xdg-shell spec means that the client is requested
to set its size by itself.
Test Plan:
1. Create a fullscreen Wayland window.
2. Toggle fullscreen off.
3. KWin should send a configure event with size 0,0 instead of 1,1.

Summary:
On Wayland we cannot switch from OpenGL to QPainter compositor as this
would break any running OpenGL application. KWin registers it's
EGLDisplay to Wayland and without OpenGL this doesn't make sense any
more. We are not able to render OpenGL buffers in the QPainter
compositor.
While it's theoretically possible to switch from QPainter to OpenGL it
doesn't make any sense for the same reason. Any running OpenGL
application would be using llvmpipe and could not be switched to proper
OpenGL.
This change stores the selected compositing type in Platform and the
implementations can use it to restrict the supported compositors. On X11
we don't need this, all other Platforms implement the restriction. Thus
it's no longer possible to switch the backends at runtime.
Test Plan:
Adjusted tests run, no runtime test as gui doesn't support
switching to QPainter anyway.

Summary:
Using the Wayland protocol for OpenGL is no longer used or useful. KWin
internal windows only use OpenGL through QtQuick. We either have the
sharing context (KWin uses OpenGL for compositing) or we have the
QPainter compositor which also turns QtQuick to use software renderer.
Thus a situation where the Wayland platform context is useful doesn't
exist any more. Removing it helps getting the QPA plugin Wayland free.
Test Plan:
Run nested KWin triggering Outline once with OpenGL and once
with QPainter compositor.

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.

Run nested KWin, triggered outline (OpenGL case) and debug console (shm case).

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).

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

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.

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.
