Description:
------------
At window,It is right,bu at unix/linux,It don't show chinese word,example:

$Graph =& Image_Graph::factory('graph', $Canvas);
// add a TrueType font
$Font =& $Graph->addNew('font', 'c:\\WINNT\\Fonts\\SIMFANG.TTF');
//$Font =& $Graph->addNew('font', '/var/www/Fonts/SIMFANG.TTF');

Test script:
---------------
<?php
error_reporting(E_ERROR);
/**
* Usage example for Image_Graph.
*
* Main purpose:
* Antialiasing usage
*
* Other:
* Setup canvas, Many plotareas with one legend, Setup fillarray (filling one
* plot with different colors depeding on dataset)
