OK, got it, thanks.

Two questions:

- If I were to look into adding a special case for non-uniform 1st to 2nd
order refinement for LAGRANGE variables, do you think this would be of
interest to include that in libMesh, or would it be too specific to
include? (I'd like to know if it's potentially of broader interest before
looking further into this.)

- How complex do you think it would be to add that special case?
