We no longer need to have the event dispatcher created before starting
the QApplication, thus we can leave it to the QPA plugin to creat it.
Also we don't need to implement our own dispatcher any more but can
use one from Qt5PlatformSupport as we link it anyways. The special
need for dispatching the WaylandServer is no longer needed as we can
explicitly dispatch it from the QPA plugin if needed.
Our QPA plugin does not require a running Wayland server at startup,
so we can move the startup after creating the application.
Nice side effect: --help works now.
A click outside a popup should close the popup and not be passed to the
window at the pointer position. Thus we only update the internal pointer
window if the internal pointer window does not represent a visible
popup.
The hack to perform the first eglInitialize in a thread is no longer
needed, as our internal QPA plugin is either able to share the
EGLDisplay or performs the potentially blocking eglInitialize in a
thread.
This introduces an own QPA plugin for KWin. QtWayland's plugin is not
a good solution for KWin as QtWayland is meant for Wayland clients and
not for a Wayland server. Given that it makes more sense to have a very
minimal QPA plugin which supports the use cases we actually have.
With our own QPA plugin we should be able to improve the following
areas:
* no need to create Wayland server before QApplication
* Qt::BypassWindowManagerHint can be supported
* no workaround for creating OpenGL context in main thread
* sharing OpenGL context with Qt
* OpenGL context for Qt on libhybris backend
The plugin supports so far the following features:
* creating a QPlatformWindow using KWayland::Client (ShellSurface)
* creating a QPlatformBackingStore using a ShmPool
* creating a QPlatformOpenGLContext with Wayland::EGL
* or creating a QPlatformOpenGLContext which shares with KWin's scene
* creating a QPlatformScreen for each KWayland::Client::Output
* QPlatformNativeInterface compatible to QtWayland
This change introduces a mechanism for internal windows to be rendered
to a QOpenGLFramebufferObject to be composited using the texture bound
to the FBO. This is useful for in-process rendering (e.g. QtQuick) and
at the same time bypassing the windowing system.
The OpenGL context of the QOpenGLFramebufferObject needs to be sharing
with the compositing OpenGL context.
In an own QPA plugin we want to make the OpenGL context sharing with
our compositing context and bypass the windowing system for OpenGL
windows. In order to achieve this we need a surfaceless context.
The AbstractBackend now forwards whether such a context can be created on
the EGLDisplay used by the Compositor.
Allows to interact with the Registry for the internal connection in
other parts of KWin and makes it possible to create more than just the
ShmPool for this Registry.
With this change libinput is less noisy and only prints errors to stderr.
In addition one could install a dedicated log handler and forward to
qCDebug and friends.
I don't understand why, but this fixes the TestXcbWrapper::testTransientFor().
Failing code fragment in question:
Window transientWindow(createWindow());
transientWindow.changeProperty(XCB_ATOM_WM_TRANSIENT_FOR, XCB_ATOM_WINDOW, 32, 1, &m_testWindow);
// let's get another transient object
TransientFor realTransient(transientWindow);
QVERIFY(realTransient.getTransientFor(&compareWindow));
QCOMPARE(compareWindow, (xcb_window_t)m_testWindow);
the QCOMPARE failed with one compareWindow being 0. It looks like the
cast from Xcb::Window to xcb_window_t in the changeProperty failed.

* Need to pass modifiers to Client::keyPressEvent
* Need to check whether move/resize ended before updating position,
otherwise it keeps stuck in move/resize after ending
not everytime the current screen changes.
a) that pollutes the geometry when the tabbox is invoked
b) it's insufficient for "Active Screen follows mouse" (the default)
c) less overhead (ok: "on multiscreen")

the (old) button effect windows used to be unreferenced
with the re-invocation of the effect. because we stopped
deleting/recreating the window, this approach failed and
the effect window was never deleted.
Unreferencing the window at proper occasion (see new hide
location) coked up - guess what - the exact same "texture is
junk" issue as for the QtQuick close button in present windows...
So we resort to the exact same stupid "hide by moving" solution
as we have there.

1. if a client has oversize, ensure to keep the titlebar in
sight
2. if a maximized client *almost* covers the entire maximization
area, users can easily be trapped to click into the missing
pixels, thus the client below.
Therfore the clients is then stuffed into one corner, with
preference to the titlebar edge and the screen area (ie.
*away* from panels and towards actual screen borders because
of fitt's law)

Let's rather not build the plugin if we don't have the dependency
then building it without OpenGL support. Simplifies the code a bit
and makes the backend overall more useful and goes along with e.g.
the Wayland one which has EGL also as a hard dependency for the
plugin.

The option NoPlugin allows to disable window decoration plugins. It
used to exist with the old decoration library but got unfortunately
lost during the switch.
This change brings back the option and also allows runtime changes
of the option.
