I don't think that it lost resolution (there wasn't much there in the
eps) but that it was JPEG encoded and got smeared around.  Edit
epstopdf to include -dColorImageFilter=/FlateEncode when it calls gs,
and it should look the same.  (I haven't tried this with gs 7.0 yes,
but it works with gs 6.50.)

It would be nice if you could pass GS parameters into epstopdf....
