  73  *  SwSpecialPos. This structure is used to pass some additional information
  74  *  during the call of SwTextFrame::GetCharRect(). An SwSpecialPos defines a position
  75  *  inside a portion which does not have a representation in the core string or
  76  *  which is only represented by one position,  e.g., field portions,
  77  *  number portions, ergo sum and quo vadis portions.
  78  *
  79  *  nCharOfst       - The offset inside the special portion. Fields and its
  80  *                    follow fields are treated as one long special portion.
  81  *  nLineOfst       - The number of lines between the beginning of the special
  82  *                    portion and nCharOfst. A line offset required to be
  83  *                    nCharOfst relative to the beginning of the line.
  84  *  nExtendRange    - Setting this identifies portions which are in front or
  85  *                    behind the core string (number portion, quo vadis)
  86  *
  87  *  Examples 1)
  88  *
  89  *      Get the position of the second character inside a number portion:
  90  *          nCharOfst = 2; nLineOfst = 0; nExtendRange = SP_EXTEND_RANGE_BEFORE;
  91  *          Call SwTextFrame:::GetCharRect with core string position 0.
  92  *
  93  *  Example 2)
  94  *
  95  *      Field A - Length = 5
  96  *      Follow field B - Length = 9
  97  *      Get the position of the third character in follow field B, core position
  98  *      of field A is 33.
  99  *          nCharOfst = 7; nLineOfst = 0; nExtendRange = SP_EXTEND_RANGE_NONE;
 100  *          Call SwTextFrame:::GetCharRect with core string position 33.
