Usage notes
- Index numbers top-level outline items from 0
- An outline item's open state is the sign of its /Count entry (ISO 32000-1 12.3.3); the method sets that sign and refreshes the counts across the whole outline, so the outline root keeps hold of the number of items visible when the document opens
- An item with no children has nothing to expand, so it is left as it is — save for taking out an /Open key which versions before 2.765.2 wrote by mistake
