`rotate` doesn't allow negative angles #21

Closed stchang closed 9 years ago

stchang commented 9 years ago

rotate from whalesong/image is currently incompatible with rotate from 2htdp/image. It should accept any real number: http://docs.racket-lang.org/teachpack/2htdpimage.html?q=rotate#%28def._%28%28lib._2htdp%2Fimage..rkt%29._angle~3f%29%29

If I recall correctly rotate in 2htdp/image didn't rotate originally. The fix might be as simple as look up what the new rotate code looks like.
