38 keep it, it will have to have derivative that *is* incident, and that
39 meets the following filter.
40
41 If it doesn't have a valid derivative (eg the derivative is fixed, or
42 the variable doesn't HAVE a derivative), we will mark the non-deriv
43 var non-ACTIVE, so anyway it will end up meeting this filter after we've
44 run integrator_ida_check_vars.
