      READ before changing/enhancing the following enum
      =================================================

      Please note: The following enum is made in a way that
      sections with smaller Y values come first.
      Thus one can construct a loop itterating over theHdFtPos values
      and so going from the top of the screen toiwards the bottom...

      Also please note that extending this enum shound NOT break the
      tripple groups (numbers 0/1/2, 3/4/5, and 6/7/8) since the
      algorithms in
      KDChartPainter::setupGeometry() and
      KDChartPainter::paintHeaderFooter() rely on this schema.
      Also don't forget to always update the auxiliary values
      HdFtPosSTART, HdFtPosHeadersSTART,
      HdFtPosHeadersEND, HdFtPosFootersSTART,
      HdFtPosFootersEND, and HdFtPosEND muessen - these are used
      fpr other itarators...
