Detailed Description

Rectangle in 2D space.

The "width/abscissa" (long axis) of the rectangle is along p0-p1, p2-p3, the "height/ordinate" (short axis) of the rectangle is along p1-p2, p3-p0.

Note, a constructor from 3 vertices is also defined The 3 vertices are to be defined in counterclockwise order, with a 90 degree corner between p_c-p_abs and p_c-p_ord.

    Modifications
     2000-05-08 François BERTEL Creation
     2000-06-17 Peter Vanroose  Implemented all operator==()s and type info
     2001-07-03 Peter Vanroose  Replaced vnl_double_2 by vgl_vector_2d
     2004-05-11 Joseph Mundy    Changed internal representation to 4 verts,
                                which allows consistent polygon operations.
                                3 vert constructor is maintained
     2004-05-14 Peter Vanroose  Added describe()
