/**
 * This is based on the work of ryan at retronetworks dot com
 * Who posted the original function on the PHP manual.
 * I had occasion to find the pixel width of the created string so now
 * a) the function returns the length 
 * and b) there's a stripped-down imagettfbbox which does the same thing
 * 
 * Ryan's original code: http://www.php.net/manual/en/function.imagettfbbox.php#51373
