note 35170 deleted from function.imagestring by aidan

Note Submitter: sk89q at yahoo dot com ---- [NEW VERSION] Fixed bottom line irregularness (didn't take into effect leading); Vertical alignment added (inspiration by those people below) resource imagestringbox ( resource image, int font, int left, int top, int right, int bottom, int align, int valign, int leading, string text, int color ) This function allows you to draw text inside a box. It will automatically wrap at the end of the line and cut the text if it is further than the bottom line. The text can be aligned vertically and horizontally. Manual new lines can be made by using \n (note that you can not escape that symbol though). The space between lines can also be set using leading (negative values are accepted).
