[metapost] Conformance to Document Structuring Conventions Specification ver 3.0

[Karl Berry]

    actually embedding the font is not a big deal. 

Cool, as long as it's optional and not the default.  Having every mp
figure include every font would be a disaster for the 90% case of the
figures being included in TeX (or other) documents where the fonts are
already present.  

By the way, perhaps I should mention that Troy Henderson wrote a program
mpstoeps to make mp output files standalone.
