This QML based version of the desktop change OSD is intended to
replace the C++ version of it.
It currently supports all of the features except adjusting to config
options, which is not yet available at all to scripts.
This script allows to have video fullscreen windows span all attached
screens creating a video wall.
This replaces the removed functionality that you could disable
xinerama support inside KWin for fullscreen windows.
