The FD_KERNINGPAIR structure is used to store information about kerning pairs.
An array of FD_KERNINGPAIR structures must be zero-terminated, which means the last FD_KERNINGPAIR structure in the array has all structure members set to zero. An array of FD_KERNINGPAIR structures must be sorted in increasing order according to an unsigned 32-bit key, calculated as follows:
wcFirst + 65536 * wcSecond.
