| * create an SFnt superclass. Eg to handle sfnt-housed postscript fonts. |
| * OpenType fonts are handled by this class, and possibly should be |
| * represented by a subclass. |
| * An instance stores some information from the font file to faciliate |
| * faster access. File size, the table directory and the names of the font |
| * are the most important of these. It amounts to approx 400 bytes |
| * for a typical font. Systems with mutiple locales sometimes have up to 400 |
| * font files, and an app which loads all font files would need around |
| * 160Kbytes. So storing any more info than this would be expensive. |
