When starting a background process on Windows, the os creates an actual new process (instead of just a new fork). Therefore, everything needs to be copied / pickled. The eye video exporter formerly used a function factory to create a function that renders pupil positions, but the returned function would not be pickleable. This is now fixed by replacing the old functionality with a callable class that can get copied to the background process.
