For the records, I would prefer to _not_ document it as
`all_intersections` being an alias for `max_trace 10`, but rather leave
the general wording as is, and instead add a note that the current
implementation still has a limit of 10 intersections in all cases.
Because I have a cunning plan. There must be a way to teach POV-Ray to
automatically re-visit an isosurface if it discards an isosurface
intersection, and we could use `all_intersections` as a keyword to
enable that behaviour.
