thanks. reducing the anti-aliasing improved the contrast, but made the rasters
uglier. So I ended up keeping the original option.

By the way, one of the options in the default value of preview-gs-options is
`-DNOPLATFONTS'. The option mentioned in the documentation of my (AFPL)
ghostscript (8.51) is `-dNOPLATFONTS'. Is the other option equivalent to this
one?

But the default dvips commands used by preview-latex have the option `-Pwww',
which are supposed to embed Type 1 fonts anyway. (Just to make sure, I created a
test.ps file using the `-Pwww' option and opened the .ps file in emacs. All of
the FontType declarations in there were Type 1 (except for the first one, which
was Type 3.) Doesn't this mean the png images are being generated from outline
fonts?
