There is something to be said for an "abstract" non-specific library
that can represent the information contained in a PDF file, however:
That would make it possible to connect a document-producing application
and a viewer application (like Evince or xpdf) or widget while bypassing
the process of generating and parsing a PDF file altogether. Without
the necessity of maintaining a complete consistent PDF file, partial
update/regeneration strategies depending on currently displayed material
could offer much better interactive response of PDF previews.
