- *  Given a "current" fontID, return a ref to the next logical typeface

- *  will call this, and if 0 is not returned, will search that font, and so
- *  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.
