-// A rectangle is a 2d shape defined by point (origin) and size (width & height)
-// vectors.  The usual rectangle maths are available.  Valid rectangles have
-// positive width and height.  Invalid rectangles will be returned for invalid
-// operations such as trying to get the intersection of two rectangles which
-// don't intersect.  Using an invalid rectangle is undefined, but it may be used
-// after "fixing" it using the fix method which will cause the size to be
-// positive and adjust the origin to be the bottom-left point.  Check the
-// validity of a rectangle using the isValid method especially if the rectangle
-// is a result of an operation which could fail.
