  22   Revision History:
  23     version 1.0, March 6, 1992.  TWAIN 1.0.
  24     version 1.1, January 1993.   Tech Notes 1.1
  25     version 1.5, June 1993.      Specification Update 1.5
  26                                  Change DC to TW
  27                                  Change filename from DC.H to TWAIN.H
  28     version 1.5, July 1993.      Remove spaces from country identifiers
  29
  30     version 1.7, July 1997       Added Capabilities and data structure for
  31                                  document imaging and digital cameras.
  32                                  KHL.
  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
  49     version 1.8  January 1999    Removed undocumented duplicate AUTO<cap> JMH
