Okay, there is now a version of dvipng at the CVS archive at savannah 
which attempts to implement raw PostScript specials.

All the code was really already in place. Unfortunately some packages 
(e.g., qtree) split their PostScript specials, so I had to add code to 
join them together again.

I also enabled PostScript headers, and this apparently made packages 
like PSTricks work.

I'd appreciate if presumptive users would test this, and report their 
problems/success.
