Well, kpathsea can be compiled stand-alone. However, this isn't
trivial since basically noone needs that.

I just can repeat: Both AT&T's and groff's eqn use the standard
PostScript glyph for the square root sign. It's not possible to get a
better appearance by scaling.
A possible solution to this situation would be to extend groff eqn so
that it uses a larger set of mathematical glyphs which, among others,
contain better shapes for large radical signs and parentheses. The
`cmex10' font used in DVI mode exists in a PS version also (attached);
it might be a worthwile exercise to add this font to groff (using the
same groff glyph names as provided for `devdvi').
Any takers to experiment with? As soon as groff finds those glyphs it
uses them...
