Generally, fields that have a WHOLE_MESH association might be valid even if the structure of the mesh changes. Thus, it makes sense for filters to pass this data pretty much all the time. Also cleaned up some code and comments to make the relationship between `MapFieldOntoOutput` and `DoMapField` more clear.
