% Define printobject and writeobject.
% These are mostly implemented in PostScript, so that we don't have to
% worry about interrupts or callbacks when writing to the output file.

% Define procedures for accumulating the space required to represent
% an object in binary form.  The procedures for composite objects (arrays
% and dictionaries) leave different results on the stack:
%	<#refs> <#chars> <simple_obj> -proc- <#refs> <#chars>
%	<#refs> <#chars> <array|dict> -proc- <array|dict> <#refs> <#chars>
% This is required so that .writeobjects can also accumulate the actual
% list of composite objects to write in the binary object sequence.
