1. htdp/world is deprecated, use 2htdp/universe instead.

2. we consider the pinhole approach to our image library as a mistake.  
To solve the problem Robby is working on 2htdp/image, a replacement  
for the image library. When it comes out (end of semester probably) it  
will support rotate and other such operations, plus comparisons will  
be much faster.
