  72  * @brief
  73  *   SdwRectangle: Not like rectangle in SODC, rectangles in Word Pro are
  74  * defined by 4 points. So they can be any posture in the two-dimensional
  75  * coordinate system. The class is used to describ such rectangles.
  76  *   The four corner points must be saved in member variable:m_nRectCorner
  77  * one after another. We assume the input order(the same order in .lwp files)
  78  * is as below:
  79  *
  80  * y ^     m_nRectCorner[3]             m_nRectCorner[2]
  81  *   |                 |--------------------|
  82  *   |                 |                    |
  83  *   |                 |                    |
  84  *   |                 |--------------------|
  85  *   |     m_nRectCorner[0]             m_nRectCorner[1]
