How do you imagine a better format PDF alternative? On the one hand, we have text-based formats. They are not serialization of the exact rendering. On the other hand, we have ps, which is, probably, too complex to be manipulated as text when rendered. PDF and dejavu do kinda both, even if quite imperfectly.

So how do we construct a file format, which can render a symbol (not necessarily a unicode one) anywhere, pixel-perfect, but still has concept of words, paragraphs, preferably tables and such?
