- Canvas manages its own progress socket event listeners and progress event data.
- Remove cancellations listener jank.
- Dip into low-level redux subscription API to watch for queue status changes, clearing the last "global" progress event when the queue has nothing in progress. Could also do this in a useEffect I guess.
- Had to shuffle some things around to prevent circular imports, so there are a lot of tiny changes here.
Big cleanup. Makes these classes easier to implement, lots of comments and docstrings to clarify how it all works.
- Add default implementations for `destroy`, `repr` and `getLoggingContext`
- Tidy individual module configs
- Update `CanvasManager.buildLogger` to accept a canvas module as the arg
- Add `CanvasManager.buildPath`
