@ -163,9 +163,12 @@ This kind of rectangle is useful when putting rectangles next to each other
and avoiding extra thick lines on the interior. For example, consider
building a grid like this:
@image-interaction[(let* ([s (rectangle 20 20 "outline" "black")]
[r (beside s s s s s s)])
(above r r r r r r))]
@image-interaction[
(define s (square 20 'outline 'black))
(define r (beside s s s s s s s s s s))
(define q (above r r r r r r r r r r))
q
]
The reason interior lines in this grid are the same thickness as the lines around the edge
is because the rectangles overlap with each other.
