Should the refinement level be copied over by DMCoarsen (and the coarsen level be copied by DMRefine)?

It's useful for diagnostics to be able to define a universal level. If I use PCMG and -snes_grid_sequence, there is effectively a sequence like

DMCreate(,&dm0); // r=0,c=0 DMRefine(dm0,&dmf); // r=1,c=0 DMCoarsen(dmf,&dmc); // r=0,c=1

I would like a way to identify dmc as being on the "same level" as dm0.
