title: How do I replace a sifr font of an existing site without changing the font size in the css?
body: <p>I've been tasked with re-skining a site that uses sifr extensively.  Unfortunately the new glyphs seem to render both taller and fatter than the old ones, necessitating changes to the font-size of every instance.   The site is quite large with many different templates and one-off page layouts, so identifying and tuning each instance will be time consuming.</p>
  
  <p>Besides cutting down on the obviously excessive use of sIFR, or getting a better font is there any other workaround?  The only thing I can think of is calculating a new font-size in javascript before I make this replacement.</p>
