well, this is actually postscript code piped to ghostscript. to
correctly extract text from it, you'd have to write a full postscript
interpreter, ie clone ghostscript in ggv, which would be quite a
difficult task... so I suppose ggv will never be really accessible.

btw, ggv for GNOME 2 is just undergoing a major rewrite. you should keep
track of the latest CVS stuff if you intend to add any functionalty to
it.
