I'm seeing small vertical positioning or sizing differences that
cause the tests to fail on Firefox on Linux.  In particular, in the
test, the top of the characters in the tests appears a pixel higher
than in the reference, but the bottoms appear even.

It's not clear to me whether this is a bug in the metrics of the
fonts, a bug in the tests for making assumptions about font metrics,
or a bug in the browser.
