   Specification for rectangles used in disjoint2 and disjoint2_optional constraints.

Fields
   x                   the x co-ordinate of the left-side of the rectangle
   y                   the y co-ordinate of the bottom-side of the rectangle
   w                   the width of the rectangle
   h                   the height of the rectangle
   b                   boolean specifying if rectangle is placed (1=placed)
