  14. ;    Modification history
  15. ;        10/04/95 - David Hayward -    Version 1.0.4 modified code so that
  16. ;                                    the driver can be build under MPW,
  17. ;                                    Metrowerks, and Symantec.  In general,
  18. ;                                    all that was required to do this was 
  19. ;                                    to add an inline-assembly jumptable
  20. ;                                    and to store all globals off of the
  21. ;                                    message manager instance context.
  22. ;                                    Also made a few changes so that the
  23. ;                                    driver can be rebuilt to support any
  24. ;                                    resolution by changing the #defines
  25. ;                                    kResolution and kPatStretch in
  26. ;                                    "CommonDefines.h"
  27. ;
  28. ;        06/14/95 - Dave Hersey -    Version 1.0.3 to fix a bug in
  29. ;                                    CustomBufferingAndIO.c when creating
  30. ;                                    high-res PICTs, and to make the size
  31. ;                                    of buffers more flexible.
  32. ;
  33. ;        05/26/95 - Dave Hersey -    Version 1.0.2 to add the new 'outp'
  34. ;                                    desktop printer resource in NewApp.c.
  35. ;
  36. ;        05/03/95 - Dave Hersey -    Version 1.0.1 to fix some minor bugs in
  37. ;                                    CustomBufferingAndIO.c.
  38. ;
  39. ;        01/14/95 - Dave Hersey -    Created from the shell of a hollowed-out
  40. ;                                    ImageWriter driver.
