  12.     Modification history
  13.         06/14/95 - Dave Hersey -    Version 1.0.3 to fix a bug in
  14.                                     CustomBufferingAndIO.c when creating
  15.                                     high-res PICTs, and to make the size
  16.                                     of buffers more flexible.
  17.  
  18.         05/26/95 - Dave Hersey -    Version 1.0.2 to add the new 'outp'
  19.                                     desktop printer resource in NewApp.c.
  20.  
  21.         05/03/95 - Dave Hersey -    Version 1.0.1 to fix some minor bugs in
  22.                                     CustomBufferingAndIO.c.
  23.  
  24.         01/14/95 - Dave Hersey -    Created from the shell of a hollowed-out
  25.                                     ImageWriter driver.
  26.  
  27.     NOTE: Relevant goodies are listed in MPW's "Mark" menu.
