Logically, that is correct.  However, AFAICT _everything_ in FreeCiv is
a circle.  I challenge you (a rather weak challenge; I'm sure you can do
it given enough time) to come up with one shape that is not a circle. 
City areas and unit vision are all circles, as is (apparently) the
"initial vision" area.  I wouldn't want to change this.

True, yet circles are still used (and are much prettier IMO).  Go
figure.  It's been suggested that for increasing vision (as from a
watchtower) circles should also be used.  circle_iterate would then be
useful here (in vision code) as well.
