+ *  SwSpecialPos. This structure is used to pass some additional information
+ *  during the call of SwTextFrame::GetCharRect(). An SwSpecialPos defines a position
+ *  inside a portion which does not have a representation in the core string or
+ *  which is only represented by one position,  e.g., field portions,
+ *  number portions, ergo sum and quo vadis portions.
+ *
+ *  nCharOfst       - The offset inside the special portion. Fields and its
+ *                    follow fields are treated as one long special portion.
+ *  nLineOfst       - The number of lines between the beginning of the special
+ *                    portion and nCharOfst. A line offset required to be
+ *                    nCharOfst relative to the beginning of the line.
+ *  nExtendRange    - Setting this identifies portions which are in front or
+ *                    behind the core string (number portion, quo vadis)
+ *
+ *  Examples 1)
+ *
+ *      Get the position of the second character inside a number portion:
+ *          nCharOfst = 2; nLineOfst = 0; nExtendRange = SP_EXTEND_RANGE_BEFORE;
+ *          Call SwTextFrame:::GetCharRect with core string position 0.
+ *
+ *  Example 2)
+ *
+ *      Field A - Length = 5
+ *      Follow field B - Length = 9
+ *      Get the position of the third character in follow field B, core position
+ *      of field A is 33.
+ *          nCharOfst = 7; nLineOfst = 0; nExtendRange = SP_EXTEND_RANGE_NONE;
+ *          Call SwTextFrame:::GetCharRect with core string position 33.
