Thanks Fabrice. After more experimentation, I found that image-converter
field of the customization alist should be:
("dvipng -fg %F -bg %B -D %D -T tight -o \"%o%b\.png\" %f")
If this also works for *nix, then I hope that the org-mode maintainers will
make this string the new default. If it doesn't work on linux, then I hope
that it's possible to come up with a string that works in both OS families
(and that could be the new default). I'll be back on Linux in a few
months, and would love to keep a simple, cross-platform .emacs file.
