// Description : This is a PHP class for generating PDF documents without
//               requiring external extensions.
//
// NOTE:
// This class was originally derived in 2002 from the Public
// Domain FPDF class by Olivier Plathey (http://www.fpdf.org),
// but now is almost entirely rewritten.
//
// Main features:
//  * no external libraries are required for the basic functions;
//  * all ISO page formats, custom page formats, custom margins and units of measure;
//  * UTF-8 Unicode and Right-To-Left languages;
//  * TrueTypeUnicode, OpenTypeUnicode, TrueType, OpenType, Type1 and CID-0 fonts;
//  * methods to publish some XHTML code, Javascript and Forms;
//  * images, graphic (geometric figures) and transformation methods;
//  * supports JPEG, PNG and SVG images natively, all images supported by GD (GD, GD2, GD2PART, GIF, JPEG, PNG, BMP, XBM, XPM) and all images supported via ImagMagick (http://www.imagemagick.org/www/formats.html)
//  * 1D and 2D barcodes: CODE 39, ANSI MH10.8M-1983, USD-3, 3 of 9, CODE 93, USS-93, Standard 2 of 5, Interleaved 2 of 5, CODE 128 A/B/C, 2 and 5 Digits UPC-Based Extention, EAN 8, EAN 13, UPC-A, UPC-E, MSI, POSTNET, PLANET, RMS4CC (Royal Mail 4-state Customer Code), CBC (Customer Bar Code), KIX (Klant index - Customer index), Intelligent Mail Barcode, Onecode, USPS-B-3200, CODABAR, CODE 11, PHARMACODE, PHARMACODE TWO-TRACKS, QR-Code;
//  * Grayscale, RGB, CMYK, Spot Colors and Transparencies;
//  * automatic page header and footer management;
//  * document encryption and digital signature certifications;
//  * transactions to UNDO commands;
//  * PDF annotations, including links, text and file attachments;
//  * text rendering modes (fill, stroke and clipping);
//  * multiple columns mode;
//  * bookmarks and table of content;
//  * text hyphenation;

	 	 * <pre>
		 *   Encoding UTF-16:
		 *
 		 *   Encoding of a single character from an ISO 10646 character value to
		 *    UTF-16 proceeds as follows. Let U be the character number, no greater
		 *    than 0x10FFFF.
		 *
		 *    1) If U < 0x10000, encode U as a 16-bit unsigned integer and
		 *       terminate.
		 *
		 *    2) Let U' = U - 0x10000. Because U is less than or equal to 0x10FFFF,
		 *       U' must be less than or equal to 0xFFFFF. That is, U' can be
		 *       represented in 20 bits.
		 *
		 *    3) Initialize two 16-bit unsigned integers, W1 and W2, to 0xD800 and
		 *       0xDC00, respectively. These integers each have 10 bits free to
		 *       encode the character value, for a total of 20 bits.
		 *
		 *    4) Assign the 10 high-order bits of the 20-bit U' to the 10 low-order
		 *       bits of W1 and the 10 low-order bits of U' to the 10 low-order
		 *       bits of W2. Terminate.
		 *
		 *    Graphically, steps 2 through 4 look like:
		 *    U' = yyyyyyyyyyxxxxxxxxxx
		 *    W1 = 110110yyyyyyyyyy
		 *    W2 = 110111xxxxxxxxxx
