Comment (by eschnett):

{{{op_copy}}} was designed to copy data from coarse to the fine level without any kind of interpolation. This would work with all data types, including integers. I don't recall whether its meaning has changed in the mean time. As I recently realized, {{{op_copy}}} does not work with cell- centred refinement since there is then no nearest point from which to copy.

We can introduce a new prolongation operator and/or introduce a way to set the desired time prolongation order per grid function group.
