Yes. This is so all animation functions use `ol.easing.inAndOut` by default. However, all the animations in `ol.View2D` override the default animation function [1], and so the default is not used, except in the animation example. The net result is that there is no change in behaviour, but the animation functions are more consistent.

[1] with the exception of `ol.animation.bounce`, for which `inAndOut` is not appropriate.
