box-bottom

Arguments: box

Returns the bottom of box. This function is setf'able. Thus:

;; We create a box object and then modify the left, top, and right
;; components using SETF and the SETF function (note the arguments
;; to the SETF function are NEW-VALUE BOX).
;; These ways work for each component.
