As we are going to consolidate the durations of show/hide animation, could you
merge these two variables?

 
 // The opacity of virtual keyboard container when show animation starts or
 // hide animation finishes. This cannot be zero because we call Show() on the
 // keyboard window before setting the opacity back to 1.0. Since windows are not
 // allowed to be shown with zero opacity, we always animate to 0.01 instead.
 const float kAnimationStartOrAfterHideOpacity = 0.01f;
 
 // The KeyboardWindowDelegate makes sure the keyboard-window does not get focus.
 // This is necessary to make sure that the synthetic key-events reach the target
 // window.
