% This dictionaty encapsulates all that is needed to generate pagelabel pdfmarks.
%
% This is provided by Leon Bottou for the benefit of the djvudigital device
% which is a device developed and maintained outside of Artifex, and which is
% not a contributed device.
%
% This device does not cope with the method used by pdfwrite to pass the pagelabels
% number tree as a 'blob' of data, but requires that the page labels be passed using
% a PAGELABEL pdfmark.
%
% We don't want to do that with pdfwrite because there is no mechanism in pdfmark syntax
% to pass a tree, which means we'd have to laboriously disassemble the pdfmarks for the
% page labels and rebuild a number tree for it. This would mean pattern matching each
% string passed via PAGELABEL to see if it could be defined as a continuation
% of the preceding string, uing prefixes. Its much easier for us just to pass the tree.
%
% Note that this code simply translates the PageLabels Number tree into a number of
% individual PAGELABEL pdfmarks, if used for pdfwrite this would result in a number
% tree which consists solely of leaf nodes, where each node has a string for its label.
% This can be considerably more verbose than the shorthand possible with a Page Label
% dictionary.

  % We do a 'save' here in order to allow us to restore at the end of the page, before
  % we run the annotations. There are two reasons for this; firstly so that the graphics state
  % at the time we run the annotations is the same as when we ran the page, secondly in order
  % to empty the font cache before we run the annotations.
  %
  % Bug #700096 an annotation uses Helvetica but doesn't embed it, however the page *does*
  % use an embedded Helvetica, which is subset and not prefixed as such. For this file to
  % render correctly we must not use the font from the page, but must find a replacement.
  % However the file for Bug #695897 has a page which uses two versions of the same font,
  % one embedded, one not. In order for *that* file to render correctly we *must* use the
  % embedded font as a substitute for the missing font. So we divorce the fonts used
  % for the page from the fonts used for Annotations, this allows both files to work as
  % expected.
  %
  % We also need a countdictstack, so that we can check the dictionaries on the dictioanry
  % stack after we run the page contents, and 'end' an extra ones before we try to restore
  % otherwise we might try to restore back to a point before one of those dictionaries existed.
