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

Note:

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

This function is a wrapper around add_actor, lower_child and child_set

this	a Box
actor	a Actor
sibling	a Actor or `null`
...	a list of property name and value pairs, terminated by `null`
first_property	the name of the first property to set, or `null`
