Since aspect manager is now on main thread, we can directly update
backend nodes safely. Track nodes which have changed properties and
notify the backend nodes as part of the frame loop.
This avoid allocating and delivering many change messages.
To follow:
- implement on all nodes
- look at backend to frontend syncing
- figure out what to do with non property messages (components
added/removed, commands, ...)

When merging states, make sure we don't add several states of the same types
with possibly different values. We should only add states with type we don't
already have.
Since the FG traversal is done from leaf to root, we know that the states we
already contain should override any state that may have been specified higher
up in the FG branch.
