+ * (the direction to slide reveal). Additionally, the size of the
+ * child allocation will not change during the animation. This is not
+ * as generally useful as an upstream GTK+ widget, but is extremely
+ * important for the panel case to avoid things looking strange while
+ * animating into and out of view.
