  33     version 1.7, July 1997       Inserted Borland compatible structure packing
  34                                  directives provided by Mentor.  JMH
  35     version 1.7, Aug 1997        Expanded file tabs to spaces.
  36                                  NOTE: future authors should be sure to have
  37                                  their editors set to automatically expand tabs
  38                                  to spaces (original tab setting was 4 spaces).
  39     version 1.7, Sept 1997       Added job control values
  40                                  Added return codes
  41     version 1.7, Sept 1997       changed definition of pRGBRESPONSE to
  42                                  pTW_RGBRESPONSE
  43     version 1.7  Aug 1998        Added missing TWEI_BARCODEROTATION values
  44                                  TWBCOR_ types JMH
  45     version 1.8  August 1998     Added new types and definitions required
  46                                  for 1.8 Specification JMH
  47     version 1.8  January 1999    Changed search mode from SRCH_ to TWBD_ as
  48                                  in 1.8 Specification, added TWBT_MAXICODE      JMH
