Rapid Enable/Disable fault tolerance #2

Closed broag closed 4 years ago

broag commented 4 years ago

Rapidly enabling and disabling head tracking has the potential to get Jabberwocky in a bad state. The current guards in place are not sufficient.

Considerations:

ARSession state has no comprehensive status or notification mechanisms.
Only one ARSession can be active at any given time.
Completions need to be executed after HeadTracking.shared.enable completes.
CameraViewController lifecycle needs to be accounted for in fault tolerance.
Synchronization with settings is required.
