      public class PDFResourceContext
      extends PDFDictionary

  The PDF resource context. 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 its 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.
