/**
 * Called each {@link #transformPage(android.view.View, float)} before {{@link #onTransform(android.view.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.
