Frozen to animation

These animations test the behaviour of a frozen to animation that adds to other animations.

Expected result:

1. The first animation should follow a decreasing wave pattern and then cease moving once it reaches the right. This is because the to animation is frozen and completely constraints movement on the y axis.
2. The second animation should follow a decreasing wave pattern but once it reaches the right should move up and down again to the full magnitude of the wave. This is because the to animation is not frozen and so the repeating wave pattern is no longer dominated.
3. The third animation should start to follow a decreasing wave pattern but then mid way through remain at a constant height. This is because once the to animation is frozen it overrides any lower priority values.
