---------------------------------------------------------------------------------
-BREAKING CHANGE! In previous versions of PHPExcel up to and including 1.7.7,
-the 3rd-party tcPDF library was bundled with PHPExcel for rendering PDF files
-through the PDF Writer.
-
-From PHPExcel 1.7.8 onwards, this will no longer be the case. The PDF Writer is
-being rewritten to allow a choice of 3rd party PDF libraries (tcPDF, mPDF, and
-domPDF initially), none of which will be bundled with PHPExcel, but which can
-be downloaded seperately from the appropriate sites. Selection of the library to
-be used, and the directory path to that library will be defined through PHPExcel
-configuration settings, allowing more flexibility.
