My suggestion was that if such case is detected, then the whole ray is
discarded and another ray is shot to another direction. The reason being
that it's easier to do that than to figure out whether the intersection
should be counted or not (there are cases where it has to be counted and
cases where it must not be counted). Making the wrong decision can result
in the wrong result (since the result of the test is a yes/no answer,
giving the wrong answer is catastrophical).
