Add a ticks counter that tells you how idle is a render process
It gives you a timedelta since the last time it was known that the renderer was active
- so far receiving a message from the renderer seems a simple heuristic.
- The goal is to use it to prioritize the use of hot renderers or do something to cold ones.
