The class of box objects. A box is created with make-box, and indicates a rectangular area in some coordinate system by specifying its left, top, right, and bottom coordinates. Boxes are useful for determining such things as a window's location and size or where to draw something on a graphical stream.
While boxes are geometric shapes, that can be drawn with drawing functions like draw-box, they are also used as data structures.
