   not visible, which is how the other layout managers work.
 
+â The expansion and alignment layout properties in all the layout managers
+  that provide them have been deprecated in favour of the equivalent ones
+  on ClutterActor; the ClutterLayoutManager implementations provided by

+  currently set fixed position to (0, 0).
