There's a lot of duplicate code in some of these functions. I know that
Activate* calls are all over the place, so it would be hard to add a bool
parameter |user_gesture| rather than doing it this way, but it's a bit
unfortunate.

 
   // Deactivates the specified contents by deactivating its container and
   // potentialy moving it to the back of the Z order.
