creating a Rectangle

by Andre Hora

Hello, To create a Rectangle in Pharo with the method Rectangle>>origin:corner:, you must provide the top left and the bottom right points. With others you have a Rectangle with area equals to zero. I just noticed that in VW it is possible create a Rectangle with other points (bottom right and top left, bottom left and top right, ...). So, shouldn't Pharo Rectangle allow the same? regards, -- Andre Hora
