  13.         10/04/95 - David Hayward -    Version 1.0.4 modified code so that
  14.                                     the driver can be build under MPW,
  15.                                     Metrowerks, and Symantec.
  16.                                     Also made a few changes so that the
  17.                                     driver can be rebuilt to support any
  18.                                     resolution by changing the #defines
  19.                                     kResolution and kPatStretch in
  20.                                     "CommonDefines.h"
  21.  
  22.         06/14/95 - Dave Hersey -    Version 1.0.3 to fix a bug in
  23.                                     CustomBufferingAndIO.c when creating
  24.                                     high-res PICTs, and to make the size
  25.                                     of buffers more flexible.
  26.  
  27.         05/26/95 - Dave Hersey -    Version 1.0.2 to add the new 'outp'
  28.                                     desktop printer resource in NewApp.c.
  29.  
  30.         05/03/95 - Dave Hersey -    Version 1.0.1 to fix some minor bugs in
  31.                                     CustomBufferingAndIO.c.
  32.  
  33.         01/14/95 - Dave Hersey -    Created from the shell of a hollowed-out
  34.                                     ImageWriter driver.
