We haven't discussed this much on the list, but my thinking is that the 
pdf backend should support much more meta data than it currently does. 
Encryption is one thing that would make sense to support, but also 
features such as page labels, table of contents, author, title, creator 
(the application using cairo) and numerous others.  It's not going to be 
in 1.0, but the API for this would probably be setters on the PDF 
surface, e.g. something like

	cairo_pdf_surface_set_author (surface, "Jane Austen");

and

	cairo_pdf_surface_set_section (surface, parent_section, "Font Level 
Hints");

and similiar.
