/**
 * Transforms FONT tags to the proper form (SPAN with CSS styling)
 *
 * This transformation takes the three proprietary attributes of FONT and
 * transforms them into their corresponding CSS attributes.  These are color,
 * face, and size.
 *
 * @note Size is an interesting case because it doesn't map cleanly to CSS.
 *       Thanks to
 *       http://style.cleverchimp.com/font_size_intervals/altintervals.html
 *       for reasonable mappings.
 * @warning This doesn't work completely correctly; specifically, this
 *          TagTransform operates before well-formedness is enforced, so
 *          the "active formatting elements" algorithm doesn't get applied.
