[metacity/wip/invisible-borders: 6/25] MetaWindow: Repurpose get_outer_rect and add get_input_rect

[Alberts Muktupāvels <muktupavels src gnome org>]

    MetaWindow: Repurpose get_outer_rect and add get_input_rect
    
    get_outer_rect now returns the visible region, and a new get_input_rect
    method returns the boundaries of the full frame, including the possible
    invisible regions. When undecorated, both do the samething.
