Extend the start and end of a list of curve frames and positions. Useful for
doing subtraction operations. Inputs are not modified in-place. If an empty
list is supplied, an error is thrown. All tangents must be normalized and
valid, make sure to call fixTangentList to the input lists. Frames
and positions lists must match in length.
