      Registering font families will help you when you want to use a font over
      and over or if you would like to take advantage of the <code>:style</code>
      option of the text methods and the <code>b</code> and <code>i</code> tags
      when using inline formatting.

      To register a font family update the <code>font_families</code> hash with
      the font path for each style you want to use.
