A PDFPage encapsulates the parsed commands required to render a single page from a PDFFile. The PDFPage is not itself drawable; instead, create a PDFImage to display something on the screen.
This file also contains all of the PDFCmd commands that might be a part of the command stream in a PDFPage. They probably should be inner classes of PDFPage instead of separate non-public classes. @author Mike Wessler
org.apache.fop.pdf.PDFPage
class representing a /Page object. There is one of these for every page in a PDF document. The object specifies the dimensions of the page and references a /Resources object, a contents stream and the page's parent in the page hierarchy. Modified by Mark Lillywhite, mark-fop@inomial.com. The Parent object was being referred to by reference, but all that we ever used from the Parent was it's PDF object ID, and according to the memory profile this was causing OOM issues. So, we store only the object ID of the parent, rather than the parent itself.
