Start seeked animators without waiting for start delay.

        AnimationHandler animationHandler = AnimationHandler.getInstance();

        animationHandler.addAnimationFrameCallback(this, (long) (mStartDelay * sDurationScale));

        if (mStartDelay == 0) {

            // If there's no start delay, init the animation and notify start listeners right away

            // to be consistent with the previous behavior. Otherwise, postpone this until the first

            // frame after the start delay.
