    wayland: request appropriate compositor version to support buffer scale
    
    With the introduction of the use of buffer scaling in ed4fcee4ct we
    must request version 3 of the compositor as that is the version of the
    surface interface that adds this new functionality. See the following
    commit in weston:

        Use wl_resource_create() for creating resources
    
        This commit sets the version numbers for all added/created objects.  The
        wl_compositor.create_surface implementation was altered to create a surface
        with the same version as the underlying wl_compositor.  Since no other
        "child interfaces" have version greater than 1, they were all hard-coded to
        version 1.
