Description:
 def to_front(intersection, intersections, unused):
 """Rotates a node to the "front". .. note:: This is a helper used only by :func:`basic_interior_combine`, which in turn is only used by :func:`combine_intersections`. If a node is at the end of a segment, moves it to the beginning of the next segment (at the exact same point). We assume that callers have pruned ``intersections`` so that there are none with ``s == 1.0`` or ``t == 1.0``. Hence, any such intersection will be an "artificial" intersection added by :func:`get_next`. .. note:: This method checks for **exact** endpoints, i.e. parameter bitwise identical to ``1.0``. But it may make sense to allow some wiggle room. Args: intersection (.Intersection):
 The current intersection. intersections (List[.Intersection]):
 List of all detected intersections, provided as a reference for potential points to arrive at. unused (List[.Intersection]):
 List of nodes that haven't been used yet in an intersection curved polygon Returns: .Intersection: An intersection to (maybe) move to the beginning of the next edge of the surface. """
