Submitted By: Ken Moffat <ken at linuxfromscratch dot org>
Date: 2017-01-24
Initial Package Version: 51.0
Upstream Status: Waiting for review (mozilla bug 847568)
Origin: OpenBSD (via gentoo)
Description: Allow use of system versions of graphite2 and harfbuzz.  This
should be regarded as experimental.  Add the options --with-system-graphite2
and --with-system-harfbuzz to use this (needs recent versions of both).
The source of this latest version is from
https://dev.gentoo.org/~anarchy/mozilla/patchsets/firefox-51.0-patches-04.tar.xz

Previous versions of the patch were at https://dev.gentoo.org/~axs/mozilla/patchsets/
