-
-  alignment-done -- boolean to administrate whether we've done the alignment already (to ensure that the process is done only once)
-
-  center-element -- element which will be at the center of the group
-    after aligning (when using
-    Align_interface::center_on_element). The center element should
-    have this object as a reference point.
