I went through the library and could not see anywhere that DTYPE was 
used for anything other than consistency.

We could do this job in two stages:
(i) Revamp the descriptor but keep gfc_dimension the same; and
(ii) Update gfc_dimension.

Most of the work is in (ii)... :-)

This has the disadvantage of two API changes but might be more within 
our capabilities.

Cheers
