+ * 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.
