 *  on. This process must be finite, and when the fonthost sees a
 *  font with no logical successor, it must return NULL.
 *
 *  The original fontID is also provided. This is the initial font that was
 *  stored in the typeface of the caller. It is provided as an aid to choose
 *  the best next logical font. e.g. If the original font was bold or serif,
 *  but the 2nd in the logical chain was plain, then a subsequent call to
 *  get the 3rd can still inspect the original, and try to match its
 *  stylistic attributes.
