Usage notes
- Each value matches the dictionary key used when looking the tree up under the catalog /Names dictionary (Dests, JavaScript, EmbeddedFiles, Pages, Templates, IDs, URLs, AlternatePresentations, Renditions)
- Pass a value of this type to THotPDF.GetLoadedNameTreeRootCount, which returns the number of name-value entries in that tree, or 0 should the document have no such tree
- Name trees store their entries as a /Names array of alternating keys and values, so the count is the length of the array divided by two
