Re: pstricks in org-mode?

[Darlan Cavalcante Moreira <darcamo@gmail.com>]

Even graphics made in tikz, that does not use postscript commands, do not appear
in DVI viewers. I haven't used the preview-latex with graphics in AucTeX, but if
it is able to view graphics made with pstricks, as it appears to be the case,
then maybe it is better to first investigate how preview-latex is able to do
this before searching for options to pass to dvipng in org-mode.

IMHO it would be even better if it was possible to use the original
preview-latex from AucTeX instead of reinventing the wheel.
