Rather than maintain copies of the entire focus stack, this PR transactionises the focus by introducing two new properties to the container state and using those when rendering. * `bool focused` means this container has actual focus. Only one container should have this equalling true in its current state. * `struct sway_container *focus_inactive_child` points to the immediate child that was most recently focused (eg. for tabbed and stacked containers).
