[gdal-dev] Adding ignored fields to layers

[Ari Jolma]

When fields are added to a layer, the field definition that is stored in 
the layer definition is created as a clone of the provided field definition.

Neither field definitions nor geometry field definitions set the ignored 
flag of the clone.

Is this a feature and not a bug?

I was already making a PR but I see in the field definition clone code 
the comment "TODO(schwehr): Can we use IsIgnored()?"

So, can we?
