// SubWrite prints text from the current position in the same way as Write().
// ht is the line height in the unit of measure specified in New(). str
// specifies the text to write. subFontSize is the size of the font in points.
// subOffset is the vertical offset of the text in points; a positive value
// indicates a superscript, a negative value indicates a subscript. link is the
// identifier returned by AddLink() or 0 for no internal link. linkStr is a
// target URL or empty for no external link. A non--zero value for link takes
// precedence over linkStr.
// The SubWrite example demonstrates this method.
