28 *  Given a "current" fontID, return a ref to the next logical typeface
29 *  when searching fonts for a given unicode value. Typically the caller
30 *  will query a given font, and if a unicode value is not supported, they
31 *  will call this, and if 0 is not returned, will search that font, and so
32 *  on. This process must be finite, and when the fonthost sees a
33 *  font with no logical successor, it must return NULL.
34 *
35 *  The original fontID is also provided. This is the initial font that was
36 *  stored in the typeface of the caller. It is provided as an aid to choose
37 *  the best next logical font. e.g. If the original font was bold or serif,
38 *  but the 2nd in the logical chain was plain, then a subsequent call to
39 *  get the 3rd can still inspect the original, and try to match its
40 *  stylistic attributes.
