After flip, an image is not "trimmed" to its drawn area

[maueroats]

Both flip-vertical and flip-horizontal screw up the bounding box handling. Apparently after a flip everything inside the bounding box is considered part of the image, not just the drawn part. Unlike DrRacket and non-flipped WeScheme images.

Sample code (first line for DrRacket only):

(require 2htdp/image)
(define good (triangle 100 "solid" "orange"))
(define bad (flip-horizontal (triangle 100 "solid" "blue")))
(beside good bad)

(beside/align "bottom"
              (frame (rotate 60 good))
              (frame (rotate 60 bad)))

Results from DrRacket 8.9 CS, as expected:

Results from WeScheme.org today:

The whitespace around the blue triangle ("bad") is expanded, presumably including the space outside of the triangle in the figure.

Definitely a serious bug, and likely related to #55 .
