//  - supports document encryption;
//  - includes methods to publish some xhtml code;
//  - includes graphic and transformation methods;
//  - includes bookmarks;
//  - includes Javascript and forms support;
//  - includes a method to print various barcode formats using an improved version of "Generic Barcode Render Class" by Karim Mribti (http://www.mribti.com/barcode/) (require GD library: http://www.boutell.com/gd/)
//  - supports TrueTypeUnicode, TrueType, Type1 and encoding;
//  - supports custom page formats, margins and units of measure;
//  - includes methods for page header and footer management;
//  - supports automatic page break;
//  - supports automatic page numbering;
//  - supports automatic line break and text justification;
//  - supports JPEG, PNG anf GIF images;
//  - supports colors;
//  - supports links;
//  - support page compression (require zlib extension: http://www.gzip.org/zlib/);
//  - the source code is full documented in PhpDocumentor Style (http://www.phpdoc.org).
