130  * following changes are done for FrontAccounting 2.0 - Joe Hunt 06.08.2008
131  * 1. /config/tcpdf_config.php is not included, commented out
132  * 2. Following 3 defines instead:
133  *    if (!defined("K_PATH_FONTS"))
134  *        define ("K_PATH_FONTS", '../reporting/fonts/');
135  *    define ("K_PATH_CACHE", '../reporting/fonts/');
136  *    define("K_CELL_HEIGHT_RATIO", 1.25);
137  * 3. ./unicode_data2.php only included if unicode is set. (in class constructor)
138  *    We only use a reduced variant of unicode_data.php (unicode_data.php).af wrap the
139  *    following defines
140  *    if (!defined("K_RE_PATTERN_RTL"))
141  *    and
142  *    if (!defined("K_RE_PATTERN_ARABIC"))
143  * 4. Parameter $unicode in constructor renamed to $uni.
144  * 5. Header function renamed to Header1 (due to conflict with FrontReport Header)
145  * 6. Line 6190, SetLineWidth (cast of values to avoid problem in PHP 5.2.6
146  * 7. Line 6261. ereg replaced by preg_match (with start and end delimiter)
147  * 8. Lines 8642,9256 and 9348. split replaced by preg_split.
