Struct JointTrack 

pub struct JointTrack {
    pub joint_index: usize,
    pub translation: Vec<Keyframe<Vec3>>,
    pub translation_interpolation: Interpolation,
    pub rotation: Vec<Keyframe<Quat>>,
    pub rotation_interpolation: Interpolation,
    pub scale: Vec<Keyframe<Vec3>>,
    pub scale_interpolation: Interpolation,
}

One joint’s animated properties. Any of the three tracks may be empty — glTF allows animating only some of a joint’s translation/rotation/scale; AnimationClip::sample falls back to the joint’s bind pose for whichever are unanimated. Keyframes within each track must be in non-decreasing time order (glTF’s own accessors are spec-guaranteed to already be).
