Try to fix a list of tangents that will be fed to a curve frame generator,
in-place. Each tangent is normalized, and zero-length tangents are replaced
by the nearest tangent.
Returns
A new list of curve tangents without any invalid tangents.
Parameters
tangents: vec3[]
A list of curve tangents (direction of the curve).
