I'd be happy to add it as a glyph.  I've got enough experience in the fonts
now with my work on shape notes that it wouldn't take long.

However, I think there's some value in having something in the distribution
that uses 'path, because that's an easy way for users to add new shapes.

So I'd like to propose that we have the task of changing \eyeglasses from
make-postscript-markup to 'path be a Frog task.

Any takers?

Thanks,
