(ccing gnus mailing list, in case someone is interested)

I ran into that the other day.

I think it would be very useful to have preview-buffer work
on non-latex buffers.

http://www.gnu.org/software/auctex/manual/preview-latex.html#ToDo has
the following paragraph which suggests this might not be trivial:

The current ‘gs.el’ interface is fundamentally flawed, not only because
of a broken implementation. A general batchable and daemonizable
rendering infrastructure that can work on all kinds of preview images
for embedding into buffers is warranted. The current implementation has
a rather adhoc flavor and is not easily extended. It will not work
outside of AUCTeX, either.

An additional convenience would be integration within gnus. Typical use
cases are:

- I receive a plain text mail from someone discussing maths, with inline
$\frac a b$. Ideally, I would just press a binding that would render the
maths with preview-buffer.

- I want to send math in an email. I would write inline $\frac a b$, and
gnus would create a multipart message with the s in the plain text
part, and images in the HTML part.
