now they are compatible with PostScript, -% not with our predilections -% * `gsave'/`grestore' grouping added (macros |g_save| and |g_restore|); -% the graphic object is embedded into a `gsave'/`grestore' pair -% * |set_BB| and |find_BB| available also in no-export mode -% * string variable |extra_eps_setup| added -% * a general purpose macro |make_list| added -% * version number appears in the header of EPS file -% * |reset_BB| performed by newly introduced |no_export_write_postamble| -% * definitions of EPS header more robust -% * macros |pos_turn|, |neg_turn|, and |is_line| more robust -% * global defaults defined as in ROEX (macro |mftoeps_default|) -% * code optimized, formatting slightly altered (e.g., the underscore -% character ending a name appears as a superscript asterisk) -% This version was released during the 9th EuroTeX meeting in Arnhem -% Version 0.66 (Tuesday, September 19th, 1995): -% * |find_BB| a bit more robust -% * |is_line| is exactly the same as in ROEX.MF (it should have been -% in version 0.65...) -% This version was released during the CyrTUG-95 meeting in Moscow -% Version 0.67 (Friday, October 27th, 1995): -% * |miter_limit| used to be a dimen;
