Added World to the API. Can be used to check world dimensions and offsets. Cleaned up and added some comment in Viewer. After removing the reference to a lot of issues arose. The frontend and preview-service seems to use it extensively. Changed the calls referencing the interactions to the ones in the API where it was aplicable, and commented out with a note added for the ones that were not aplicable. We proably need to expose a generic way to manipulate the camera from the API
