These properties provide a way to influence the userspace with regard
to positioning of the outputs and also enable it to look for new
preferred modes when hotplug interrupts occur. 

These properties are currently used by other virtual GPU drivers
such as vmwgfx and qxl.

Testcase: After positioning the VMM's (e.g, Qemu) windows on various
monitors and launching the Guest VM, run the get-state tool (tools/
get-state.py) associated with Mutter to ensure that the Hosts' and
Guests' outputs are aligned.
