You better throw in a little interpolation in that recipe:
sphere {
0.0, 1
texture {
pigment {
image_map {
jpeg "earth.jpg"
once
map_type 1
interpolate 4
}
}
}
}
Note that the info in the docs regarding interpolation was probably written on a
bad day. Type 4 is what people should use in general since it delivers smoother
results (which is a good thing).
