Original Gist: <a href="http://lea.verou.me/2013/03/easily-center-text-vertically-with-svg/">lea verou's "Easily center text vertically, with SVG!"</a><br/>
I've adapted the code to create a pure-SVG alternative to <a href="http://fittextjs.com/">fittext.js</a><br/>
I assume that the resizing itself will always be proportional, otherwise you'll have to change the preserveAspectRatio attribute to fit your needs.<br/>
