Calendar macro for FinalWriter (SoftWood)

   This macro can create three different types of calendars: Portrait,
   double-portrait, and landscape.  
   
   Two versions are included.  The first (calendar.fw2) is suitable for FW 2.x
   only.  The second (calendar.fw3) works only under FW3.  Both now get
   user input through commands wholly internal to FW.  Therefore, the ADOS
   specific versions are gone for good (hopefully).

   SoftWood has changed the way text blocks are handled between FinalWriter 2
   and FinalWriter 3.  This has had the effect of slowing down the macro
   considerably because each text-block must be redrawn before its width
   is updated.  Newer (Jan. 3, 1995) and later have corrected this problem,
   but I've left the code alone for backwards compatibility.

   Also, all versions of FW3 have started measuring text blocks from the
   font's baseline instead of its top, which is why the FW2 macro doesn't
   work properly under FW3.

-----------------------------------------------------------------------------

   Portrait produces a standard 8.5x11 page with a single calendar.
   Double portrait produces a standard 8.5x11 page with two calendars.
   Landscape produces a standard 11x8.5 page with a single calendar.

   While it should handle leap-years, this feature has not been
   exhaustively tested.  The fonts and margins are designed to be
   user-customizeable.  Certain default values (in inches) have been
   hardcoded into the variables 'top_margin', 'bottom_margin', and 
   'side_margin' to produce the largest calendars on my DeskJet.  You
   can change these if you need a smaller calendar or if the calendars
   print incorrectly on your setup.

   If you change the default fonts, you may have to experiment with their
   sizes and widths to get an appropriate look.

   If you find any bugs, let me know and I'll try to rectify them.

   Disclaimer: I take no responsibility for problems that may result from using
               this macro.


   History: Unnumbered first release:   Did not realize that 'requestchoice' is
                                        found only in OS3.x and above, so 2.x
                                        users were out of luck.

                                 1.0:   Created a second macro using 'RequestText'
                                        which is built in to FinalWriter instead
                                        of 'requestchoice'

                                 1.1:   Got a brain transplant and realized that
                                        FinalWriter DOES have a way to get user
                                        input from a requester.

                                        Implemented FW's built-in requester,
                                        eliminating ADOS specific versions
                                        of the macro.

                                        Discovered that FW3's handling of text
                                        blocks (among other things) is different
                                        from FW2.x, so had to implement version
                                        specific macros.
