it depends on what you want to test. i think what needs testing is
a) do we finally get the same glyphs in the same places
b) do we get the same kerning/ligs
c) do we get generally the same space
all that would be checked by either method i guess as long as there
are no changes. if there are change then i think a dvitype output
would help to pin them down (don't know the other tool but i guess
there it would be more difficult to anderstand the difference)
