/**
     * Called each {@link #transformPage(View, float)} before {{@link #onTransform(View, float)}.
     * <p>
     * The default implementation attempts to reset all view properties. This is useful when toggling transforms that do
     * not modify the same page properties. For instance changing from a transformation that applies rotation to a
     * transformation that fades can inadvertently leave a fragment stuck with a rotation or with some degree of applied
     * alpha.
     *
     * @param page     Apply the transformation to this page
     * @param position Position of page relative to the current front-and-center position of the pager. 0 is front and
     *                 center. 1 is one full page position to the right, and -1 is one page position to the left.
