Warning: pack_before is deprecated since 1.10.
Adds actor to this, placing it before sibling, and sets layout properties at
the same time, if the LayoutManager used by
this supports them
Use insert_child_below instead.
To set specific layout properties, use child_set
If sibling is null then actor is placed at the beginning of the list of children, to be allocated
and painted below every other child
