[metapost] luamplib

[Dan Luecking]

As luamplib is basically a (lua)latex package, it seemed a good
idea to find out what is making it fail with regard to
elliptical pens, as reported by Dirk Laurie. (The suggestion to
use context is basically a nonsuggestion for most latex users).

After a great deal of searching and experimentation I found the
following fix (which would probably have been immediately obvious
to an expert):

In texmf-dist/tex/luatex/luamplib/luamplib.lua, change all occurance of
    luamplib.pen_info
to
    mplib.pen_info

Regards,
Dan
