[racket] 2htdp/image question
I believe this has been fixed in the latest GIT version. If someone
has the opportunity and interest to verify that under windows, I would
be most grateful.
More details can be found here, on the underlying issues (where to
draw lines for rectangles):

(The change I made is to make the outline in empty scene actually draw
entirely inside the scene instead of using an "outline" rectangle.)
