Determines the intersection of two time intervals. If they do not intersect, an
empty time interval,
czm_emptyRaySegment, is returned.Example
czm_raySegment i0 = czm_intersection(czm_raySegment(1.0, 2.0), czm_raySegment(3.0, 4.0)); // Empty czm_raySegment i1 = czm_intersection(czm_raySegment(1.0, 3.0), czm_raySegment(2.0, 4.0)); // (2.0, 3.0)
