25 * This is a class annotation that signals that it is safe to create
26 * a native interpolator counterpart via {@link NativeInterpolatorFactory}
27 *
28 * The idea here is to prevent subclasses of interpolators from being treated as a
29 * NativeInterpolatorFactory, and instead have them fall back to the LUT & LERP
30 * method like a custom interpolator.
