once virtual machine is up and running hitting the maximize button on the title 
bar of qemu maximizes the window.
hitting ctl+alt+F makes window pixel per pixel but not full screen (smaller) 
and leaves the last scaled image in the background.
hitting the maximize button on the title bar again sends it to full screen.
hitting ctl+alt+F does not return to windowed mode.
