I think you can simplify the sphere-plane intersection. Just compute the
signed distance D of the sphere center from the plane. If D > r, the
sphere is visible. If -r <= D <= r, the sphere is partially visible. if
D < -r, it's invisible.

Also, wine people like tests. You should probably add some.

-f.r.
