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