   5 // Defines a simple integer rectangle class.  The containment semantics
   6 // are array-like; that is, the coordinate (x, y) is considered to be
   7 // contained by the rectangle, but the coordinate (x + width, y) is not.
   8 // The class will happily let you create malformed rectangles (that is,
   9 // rectangles with negative width and/or height), but there will be assertions
  10 // in the operations (such as Contains()) to complain in this case.
