This class represents points of a quadrilateral, in PDF coordinate system. The order of points in a quadrilateral should be as follows:

• The first point is the point in left-top corner of the quadrilateral.
  
• The second point is the point in right-top corner of the quadrilateral.
  
• The third point is the point in left-bottom corner of the quadrilateral.
  
• The fourth point is the point in right-bottom corner of the quadrilateral.
