[Paulo van Breugel <p.vanbreugel@xxxxxxxxx>]

Just FYI, I compiled the latest version of dvisvgm (Ubuntu 14.04 still
packages the ancient 1.2.2). With version 1.14.1, the multiplication sign
(x) is rendered as such. Still, the formula still doesn't look great (see
attached), so the even with the latest dvisvgm version the -n flag is
required.
