    Add activeViewportX and activeViewportX members to the
    CompWindow struct to keep track of the viewport the window
    was last active in. This can be used to more properly calculate
    to which window the input focus should be moved to and the
    compareWindowActiveness function has been added to make this more
    convenient.
