Provides functionality for working with Rectangles. This class extends the RoundedRectangle class and thus has all of its functionality (and also the functionality of the Rectangle class, which RoundedRectangle extends). @author Ruben Swieringa ruben.swieringa@gmail.com www.rubenswieringa.com www.rubenswieringa.com/blog @version 1.0.0 edit 5b* * This class is a slightly stripped-down version of the original @ax-lib-flex-book-com-rubenswieringa-geom-SuperRectangle class (the unfinished method getCornersInbetween() has been removed) Before modifying and/or redistributing this class, please contact Ruben Swieringa (ruben.swieringa@gmail.com).
