    boxPointer: Add compatibility API
    
    Because we're late in the cycle, and don't know how many
    extensions actually rely on this API, this commit adds
    back the BoxPointer.show() and .hide() functions, with
    warning messages to notify consumers that this is going
    to be removed.
