% In the above \Ginclude@eps, llx, lly, urx, and ury are translated to match
% the -dEPSCrop option for Ghostscript to convert eps to pdf.
% In the case of eps files created by MetaPost, the files are included
% directly without the help of Ghostscript. That is, we have to translate
% the origin accordingly if we use \Ginclude@eps for eps files created by
% MetaPost. In TeX Live 2015, the translation of the origin was the default.
% After TeX Live 2016, however, the translation of the origin is enabled only
% if the --mvorigin option is given for xdvipdfmx
% This may be a bit inconvenient, especially as
% xdvipdfmx is usually called as a pipe. Therefore we introduce a new suffix
% .mps(or .MPS) to support inclusion of eps files created by MetaPost without
% the option --mvorigin.
