[tex-live] mvorigin option in (x)dvipdfmx

[Akira Kakuto]

Dear David,

> So currently I see no reason not to change xetex.def

I believe that you can rewrite dvipdfmx.def and xetex.def
for eps inclusion as follows;

Read several lines of foo.eps (10 lines may be enough).
If a line whose first 19 characters are exactly
%%Creator: MetaPost
is found, then use an equivalent of the present \Ginclude at mps,
otherwise use an equivalent of the present \Ginclude at eps.
And you discard .mps (.MPS) suffix.


Then all is fine and nothing is necessary to change.
--mvorigin option becomes redundant and can be removed
in TeX Live 2017.

Best,
Akira
