title: SIFR 3 text resizing to fit width
body: <p>I'm using sifr 3 and trying to fit h1's on a single line but within a set width of 400px.  By default, if there's too much text, it drops onto the next line.  I've used forceSingleLine: true but then the text just stretches across the 400px width.  Is there a method which will resize the text to fit in the width AND stay on a single line?</p>
  
  <p>Thanks</p>
