* This method lets you format any substring of your text. If you give an alignment>0 (HORALIGN_NOTHING=0), your

* will be resetted by resets, that will be inserted at the end of your substring. For example:
* getFormattedItem("hello", 10, HORALIGN_RIGHT, PRT_FONT_CURSIVE+PRT_FONT_BOLD, PRT_FONT_NCURSIVE+PRT_FONT_NORMAL)
* returns: "(s1S(s3Bhello (s0S(s0B"
