(** Write a PDF document to an [Pdfio.output], optionally encrypting and/or
linearizing. For now, linearization will not preserve object streams. If
[?preserve_objstm] is set (default is false), object streams which were in the
original file will be preserved. If [?create_objstm] is set (default is false),
additional new object streams will be created. To re-encrypt the file using its
existing encryption, provide the user or owner password in the [?recrypt]
argument. The unlabelled boolean argument is true if linearization is required.
