Adding a fade-out animation to GestureNav overlays.
Making it so GestureNav overlay screenshots fade out instead of disappearing
abruptly when the overscroll gesture finishes. When the sscreenshot completely
matches the content (which should be true in most cases), this creates an
effect of content turning from grayscale to color.
