	Filter all fields and all rows in a recordset and returns the
	processed recordset. We scroll to the beginning of the new recordset
	after processing.

	We pass a recordset and function name to RSFilter($rs,'rowfunc');
	and the function will be called multiple times, once
	for each row in the recordset. The function will be passed
	an array containing one row repeatedly.

	Example:

	// ucwords() every element in the recordset
	function do_ucwords(&$arr,$rs)
	{
	foreach($arr as $k => $v) {
	$arr[$k] = ucwords($v);
	}
	}
	$rs = RSFilter($rs,'do_ucwords');
	*/
	function &RSFilter($rs,$fn)
	{
	if ($rs->databaseType != 'array') {
	if (!$rs->connection) return false;

	$rs = &$rs->connection->_rs2rs($rs);
	}
	$rows = $rs->RecordCount();
	for ($i=0; $i < $rows; $i++) {
	$fn($rs->_array[$i],$rs);
	}
	if (!$rs->EOF) {
	$rs->_currentRow = 0;
	$rs->fields = $rs->_array[0];
	}

	return $rs;
