* Transactions enable us to perform atomic layout updates.
*
* When we want to make adjustments to the layout, we create a transaction.
* A transaction contains a list of affected containers and their new state.
* A state might contain a new size, or new border settings, or new parent/child
* relationships.
*
* Calling transaction_commit() makes sway notify of all the affected clients
* with their new sizes. We then wait for all the views to respond with their
* new surface sizes. When all are ready, or when a timeout has passed, we apply
* the updates all at the same time.
