Feature.  Or at least intentional.  You can map range
RealTypes of your FlatField to SelectRange and still
get volume rendering, but if you map domain RealTypes
to SelectRange that can change the topology, so the
current default DataRenderer punts.

You can achieve the same thing by resampling your
FlatField to a Linear3DSet with restricted ranges of
domain values.

Cheers,
Bill
