bug 1218576 - Support remote accumulation via JS histograms. r=gfritzsche The JS histograms, too, need to dispatch their accumulations from child to parent. JSHistograms_Add now only supports histograms that are in gHistogramsMap or that were created in the parent process. After bug 1288745, maybe we'll be able to change this to be less convoluted.

   * Each of these data members make a copy

   * you own the memory.
   * The following three pieces of data are needed
   * to create a DC for printing. These are typcially 
   * gotten via the PrintDLG call ro can be obtained
   * via the "m_pd" data member of the CPrintDialog
   * in MFC.

   * On Windows we use the printable width and height for the printing surface.
   * We don't want to have to create native print device contexts in the content
   * process, so we need to store these in the settings.
   * Storing in Inches is most convenient as they are retrieved from the device
   * using fields which are in pixels and pixels per inch.
   * Note these are stored in portrait format to ensure that we can take account
   * of our own changes to the orientation print setting.
