* Transactions enable us to perform atomic layout updates.

|
|
* A transaction contains a list of containers and their new state.
|
|
* A state might contain a new size, or new border settings, or new parent/child
|
|
* relationships.
|
|
*
|
|
* Committing a transaction 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.
|
|
*
|
|
* When we want to make adjustments to the layout, we change the pending state
|
|
* in containers, mark them as dirty and call transaction_commit_dirty(). This
|
|
* create and commits a transaction from the dirty containers.
