Comment 72 for bug 1189850

Reading http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/www-client/firefox/firefox-19.0.2.ebuild?view=markup it seems that the use of system-cairo has been dropped. Which is a shame.

On the positive news though the latest unstable cairo has dropped the buggy gradients patch (unless legacy-drivers is set).
