Okay, the details are at ComplexRepresentations now.  Racket, Kawa, Chez,

even though they don't support mixed-exactness complex numbers.

There are two reasonable semantics for (image-part x) for rational x.

One is exact 0, the other is to copy the exactness from x.  There

was a bug in Chibi - it now always returns exact 0.
