Every key and range a shot document may use.

Every key and range a shot document may use: the camera (keys or an orbit), the sun, the air and fog, and the subjects (forms, characters, animals, open country and primitives) placed by position or by time keys. The same keys go in a video shot clip's extra. A zone subject and a terrain subject name a shipped world by id in their world key (see raster_render). Costs no units.
