The following features have been added with this version of the product.

Added GcPdfDocument.MergeWithDocument(GcPdfDocument sourceDoc, MergeDocumentOptions options) method. Use this method to combine pages from different PDF documents.
Added constructor FormXObject(GcPdfDocument doc, Page page). It allows to insert pages from a PDF document into another document as images, and allows to duplicate a page reusing page resources.
