  * <li> Blending is the action of mixing between 2 successive animation {@link BlendableAction}s by interpolating their transforms and

  * a blend value of 1 and the second action will use the blend space weight as a value for the interpolation. </li>
  * <li> In case of (Blending weight = 0), the blending hasn't started yet, only the first action will be interpolated at (weight = 1). </li>
  * <li> In case of (Blending weight = 1), the blending is finished and only the second action will continue to run at (weight = 1). </li>
