Rectangular domains without anisotropic cells

Currently, the only way to do this is by increasing the refinement in one direction, but it doesn't work well with AMR. Might need to also be an integer-only type of thing. I was thinking connected cubes/squares. Is it possible?

Don't think there's much of a way around this with octree grid refinement.

At most, we can use 1 less subdivision with anisotropic grid refinement. Don't think this is supported well with the global coarsening multigrid.

Not planned for 3.0, but I'll leave the issue open for the future.

One potential way is to manually move the points on the coarsest mesh. However, this would be a bit involved when dealing with AMR.

Not planned for 3.0, but maybe in the future.
