Maybe we don't need one.  Look what I just came across on my Linux box,
in file /usr/share/doc/packages/libEMF/README:

libEMF is a library for generating Enhanced Metafiles on systems which
don't natively support the ECMA-234 Graphics Device Interface
(GDI). The library is intended to be used as a driver for other
graphics programs such as Grace or gnuplot. Therefore, it implements a
very limited subset of the GDI.

I wonder, if he's seeing gnuplot as part of his intended target audience,
why we never heard of this. Or did we, and I just forgut.

I does seem to have a problem with gnuplot's EMF files, though.  In
particular, its 'printemf' tool complains 

GetEnhMetaFileW warning: read unknown record type 84 of size 80
GetEnhMetaFileW warning: read unknown record type 84 of size 84
[... several more ...]

Seems like that is about our EMF_put_text() calling

    EMF_write_emr(84, 76 + len * 2);    /* exttextoutw, yes it's the 
16bits char version! */

Note that this little snippet from libEMF also contains a valuable hint
at the actual EMF definition.  Google finds:
