Summary:
When a plasma session quits, the order of plasmashell and clients quitting is undetermined.
This looks bad as our desktop background disappears quite early. Rather than changing the real order, we can have kwin reference the last pixmap of any desktop and hold on to it.
Lasting till the compositor quits means it stays on the X frontbuffer till X quits and the experience is seamless.
Test Plan: Logged out (with relevant other ksmserver patches)

Summary:
Currently kwin opens a second ICE connection to ksmserver in order to
tell the state of kwin's whether we're logging out and saving clients or
not.
This requires that kwin launches after ksmserver to have the connection
which is a dependency I want to break.
Practically this code is already ksmserver specific as it relies on some
custom code that sends the first saveState request to kwin first.
Instead we can replace it with a bespoke IPC over DBus and siplify the
code both end. This will allow several other future enhancements that we
want with regards to handling the session state, as well as make an
effort platform agnostic session management, as well as cleaning up some
complex code.
Ksmserver calls into kwin, rather than having kwin watch ksmserver state
to allow us make sure it's race free.

Summary:
Won't make things go much faster since everything that was
being passed by value is refcounted but still const & is a bit faster
than refcounting
For shared pointers instead of adding const & we move them into the
destination variable saving some cpu usage but at the same time making
clear the pointer is being stored by not being const &

Summary:
The EGL platform might go away at any time through reconfiguration or because
of a graphic error. KWin then resets the graphics. The dmabuf implementation
must respect that and recover from a graphics reset by recreating all EGL
images for existing buffer.
This assumes that we won't change our graphics API mid-session and that
supported plane and modifier configuration stays constant.
In practise we remember all current dmabufs in a single map and only remove
them if the client did destroy the resource.

Summary:
If no conversion functions are provided for a QObject-subclass, then
QScriptEngine will use QScriptEngine::newQObject() method without any
special options to convert an instance of that QObject-subclass to a
QScriptValue. However, it's very important that every client object is
wrapped with PreferExistingWrapperObject option. We need that option
because a script may set a property on a client object and that property
must remain until it's deleted by the script.

Removes over 100 lines of rather confusing code, implicitly introduces a
sharedEngine. Doesn't perform hide/show by moving a window offscreen.
As for the freeze, proving that EffectQuickView covers this case without
lots of extra C++ is an important pre-requisite for ever moving this
effect to a magic declarative API.
General code structure remains the same.

KWin doesn't use Qt scaling and as such the icon remains tiny.
Instead, make it follow the cursor size as the user is likely to have larger cursors on high dpi.
