From 90fa6203ad032fe161d85a3e580941ce3d1216f0 Mon Sep 17 00:00:00 2001
From: Robin Watts <robin.watts@artifex.com>
Date: Wed, 8 Feb 2017 13:32:07 +0000
Subject: Add SVG_TEXT_AS_TEXT define.

Build with this defined, and we no longer send text as
reusable symbols, but instead send it as genuine text,
with all the potential problems (mismatching fonts etc)
that this entails.

Requested by a customer.
