Arguments: box dx dy
Modifies and returns box by subtracting dx from its left, adding it to its right, subtracting dy from its top, and adding it to its bottom, producing a box (* 2 dx) wider and (* 2 dy) higher. dx and dy must be fixnums. This function is effectively equivalent to
(setq box
(make-box (- (box-left box) dx) (- (box-top box) dy)
(+ (box-right box) dx) (+ (box-bottom box) dy)))
