There are three potential variants to add a child inside a Box
with a BinLayout:
- clutter_box_pack(), a variadic argument function which
allows passing arbitrary LayoutMeta properties and values;
- clutter_bin_layout_add(), which uses the backpointer to
the container from the LayoutManager and sets the layout
properties directly without GValue (de)marshalling
- clutter_container_add_actor() and
clutter_bin_layout_set_alignment(), similar to the
clutter_bin_layout_add() function above, but split in two
The test-box interactive test should exercise all three variants.
