Function cubic_interpolate_angle_in_time 

pub fn cubic_interpolate_angle_in_time(
    from: f64,
    to: f64,
    pre: f64,
    post: f64,
    weight: f64,
    to_t: f64,
    pre_t: f64,
    post_t: f64,
) -> f64

Cubic interpolates between two rotation values with shortest path by the factor defined in weight with pre and post values. See also [method lerp_angle].

It can perform smoother interpolation than [method cubic_interpolate] by the time values.
