  54  * TrueTypeFont is not called SFntFont because it is not expected
  55  * to handle all types that may be housed in a such a font file.
  56  * If additional types are supported later, it may make sense to
  57  * create an SFnt superclass. Eg to handle sfnt-housed postscript fonts.
  58  * OpenType fonts are handled by this class, and possibly should be
  59  * represented by a subclass.
  60  * An instance stores some information from the font file to faciliate
  61  * faster access. File size, the table directory and the names of the font
  62  * are the most important of these. It amounts to approx 400 bytes
  63  * for a typical font. Systems with mutiple locales sometimes have up to 400
  64  * font files, and an app which loads all font files would need around
  65  * 160Kbytes. So storing any more info than this would be expensive.
