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

  82  *   |                 |                    |
  83  *   |                 |--------------------|
  84  *   |     m_nRectCorner[0]             m_nRectCorner[1]
