[cairo] font lifetime

[Alexander Larsson]

I'm making xpdf work with the new font changes, and I have a question.

If i call cairo_ft_font_create_for_ft_face with a FT_Face. How do I know
how long i need to keep the FT_Face around? The cairo_font_t object is
passed around internally in cairo, and can end up in all sorts of caches
and stuff, complicating its lifecycle.
