[PATCH] Add TeX Gyre fonts.

[Ricardo Wurmus]

Attached is a patch to add the TeX Gyre font collection in OTF format.
There is another archive available for download which includes a lot
more formats and documentation, but I think this flat zip file with the
OTF files is sufficient.

The fonts are released under the “GUST font license”, which is legally
equivalent to LPPL v1.3c as it just contains an optional request.

The TeX Gyre fonts are required by the latest version of Lilypond, so I
think it is useful to have them.  (Also: they are pretty.)
