A new backend which doesn't present the rendered output. It uses a QPainter scene, renders to a QImage but doesn't present it anywhere. Thus a real virtual backend. By exporting the environment variable KWIN_WAYLAND_VIRTUAL_SCREENSHOTS the backend creates a temporary dir, prints the path to std-out and saves each rendered frame into that directory. Of course with exit it will be deleted again.
