Actually, the problem is that the placement of the figure is not where
I want it to be.  With a correct and true EPS and the 'h' option would
give a very good placement.  It would still be nice to produce a
metapost file and scale it to fit nicely and place text next to it,
but I am guessing that I am hoping for some miracles.
