Nope... again, not unless you know something else (like how many verticies
there are in between the two points). You could probably come up with a good
guestimate, though, since there would only be 4 possible values for X, all of
which you could calculate (there could be either 0,1,2,or 3 verticies of the
inscribed octagon in between the two points). Then you could concievably find
the answer that appears to match most closely-- but that assumes you have can
even make a good guess...
