  API VERSIONING INFORMATION

  The RIVA API is versioned as MAJOR.MINOR.VERSION.REVISION
  The MAJOR is incremented for major product/architecture changes
      (and then MINOR/VERSION/REVISION are zeroed)
  The MINOR is incremented for minor product/architecture changes
      (and then VERSION/REVISION are zeroed)
  The VERSION is incremented if a significant API change occurs
      (and then REVISION is zeroed)
  The REVISION is incremented if an insignificant API change occurs
      or if a new API is added
  All values are in the range 0..255 (ie they are 8-bit values)
