<h3>Log Message</h3>
<pre>Use OpenType MATH fonts by default
https://bugs.webkit.org/show_bug.cgi?id=133603
Patch by Frederic Wang <fwang@igalia.com> on 2016-04-20
Reviewed by Alejandro G. Castro.
No new tests. This is already tested by pixel tests like roots.xhtml.
However, new math fonts are not used during test execution.
* css/mathml.css:
(math): We use only a list of known OpenType fonts with a MATH table but keep some pre-installed fallback fonts for OS X and iOS.</pre>
