Hmm. :)
I'd rather prefer if fig2dev could handle it by itself. It seems
they're still actively developing it, http://www.xfig.org/
announces the betas for an upcoming version 3.2.4. Since they're
already using pnmtopng internally, it shouldn't be too hard to
teach fig2dev about PNG background colors.
I tried to make a quick patch, but it doesn't work yet...

Galeon can (that's what i'm using now). Already Netscape 4.76
can't handle the background transparency in PNGs although it can
handle it in GIFs. :-(

Probably, yes. Until reading the source of fig2dev, i didn't know they
require ghostscript and netppm, i need to add this to the prerequisites
of the FreeBSD packages as well...
Please go ahead and commit that, i'll still see to send a patch to the
xfig maintainers anyway.
