/* fribidi_remove_bidi_marks - remove bidi marks out of an string
 *
 * This function removes the bidi and boundary-neutral marks out of an string
 * and the accompanying lists.  It implements rule X9 of the Unicode
 * Bidirectional Algorithm available at
 * http://www.unicode.org/reports/tr9/#X9, with the exception that it removes
 * U+200E LEFT-TO-RIGHT MARK and U+200F RIGHT-TO-LEFT MARK too.
 *
 * If any of the input lists are NULL, the list is skipped.  If str is the
 * visual string, then positions_to_this is  positions_L_to_V and
 * position_from_this_list is positions_V_to_L;  if str is the logical
 * string, the other way. Moreover, the position maps should be filled with
 * valid entries.
 * 
 * A position map pointing to a removed character is filled with \-1. By the
 * way, you should not use embedding_levels if str is visual string.
 * 
 * For best results this function should be run on a whole paragraph, not
 * lines; but feel free to do otherwise if you know what you are doing.
 * Deprecated.  Use fribidi_remove_special_chars instead.
 *
 * Returns: New length of the string, or \-1 if an error occured (memory
 * allocation failure most probably).
