While this is the freetype we run the tests with, it isn't very interesting to
fuzz because  it's really old (it's the one in precise). It is unlikely that any
findings would be current.

Just wanted to point out that running this against any of the targets in
Chromium is strictly less interesting that running against FreeType tip of tree
using their build system. We do try to keep up to date these days, but there is
a big difference between continuous and once a month or so.
