For straight lines, Lottie exports control points conincident with the
vertices. We can detect this case and emit more efficient lineTo's.
One wrinkle: we can only apply this power-reduction post-interpolation
(otherwise the path verbs and point count would not be guaranteed to
match). Hence we store explicit shape data and defer the SkPath
conversion.
