    wayland: don't leave root window values uninitialised
    
    Under Wayland we don't know the absolute position of the device but there are
    some API calls that expect to get an root window position. Previously we were
    not assigning any value to these out parameters potentially leaving the values
    undefined.
    
    This change returns the current surface relative position of the device.
