     * @Function:

     *
     * @Description:
     *   A driver method used to return the kerning vector between two
     *   glyphs of the same face.
     *
     * @Input:
     *   face ::
     *     A handle to the source face object.
     *
     *   left_glyph ::
     *     The index of the left glyph in the kern pair.
     *
     *   right_glyph ::
     *     The index of the right glyph in the kern pair.
     *
     * @Output:
     *   kerning ::
     *     The kerning vector.  This is in font units for
     *     scalable formats, and in pixels for fixed-sizes
     *     formats.
     *
     * @Return:
     *   FreeType error code.  0 means success.
     *
     * @Note:
     *   Only horizontal layouts (left-to-right & right-to-left) are
     *   supported by this function.  Other layouts, or more sophisticated
     *   kernings, are out of scope of this method (the basic driver
     *   interface is meant to be simple).
     *
     *   They can be implemented by format-specific interfaces.
