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