  30 ;;;
  31 ;;; To add a new layout:
  32 ;;;   1- define your own layout: a method returning the real size of the
  33 ;;;      child in screen size (integer) as 5 values (rx, ry, rw, rh).
  34 ;;;      This method can use the float size of the child (x, y ,w , h).
  35 ;;;      It can be specialised for xlib:window or frame
  36 ;;;   2- Define a setter function for your layout
  37 ;;;   3- Register your new layout with register-layout or create
  38 ;;;      a sub menu for it with register-layout-sub-menu.
