Defines the minimum allowed interval time for process timers.
Notes
When a process is run, it's tasks will be processed across several game ticks if necessary to avoid game lag.
In extreme cases, it's possible for several new runs of the process to start before a previous run has finished.
When more than PROCESS_MAX_QUEUE runs are queued, the API will generate warning messages indicating the need for developer attention.
For this reason, PROCESS_INTERVAL_MIN ensures that trigger intervals are at least 500ms (at time of writing) to reduce the chances of PROCESS_MAX_QUEUE being reached.
