that's really nice.  Indeed I wanted to write something like that for
quite some time, but I never did so...

Anyway, you could make it even better by making it a generic viewer for
DVI, PostScript and PDF files.  ImageMagick's `convert' tool can convert
any of those formats to PNG.

    $ convert <pdf/dvi/ps file> </some/dir/>bar.png

converts every page to a file bar-X.png in /some/dir/ where X is a
number starting with 0 (page 1).

I'm pretty sure that convert has an option to crop parts of the margins
of the pdf/ps/dvi files, so that you can make best use of the emacs
window's space.

What do you think?
