TeXGyre Fonts

[David Carlisle]

this just came up at

https://github.com/latex3/fontspec/issues/533

It's true that xetex (for some reason) is picking up the preferred family
name and loading the companion font on a request for
TeX Gyre Termes Math, but looking at the description of that field at

https://developer.apple.com/fonts/TrueType-Reference-Manual/RM06/Chap6name.html

I think the font is correct: this field groups this companion font under
the main family in relevant menu interfaces.

most likely xetex should just not see this field at all.
