I'm pretty sure our needs are simple for image coarsening, but I'm going to cc Manuel and David because I seem to recall that the levels of linear interpolation available on PETSc grids are only suitable for image rendering, not, for example, obtaining an accurate low-resolution coarsening of a solution that you could do numerical analysis on, and I don't remember if they had grander ambitions for DA interpolation before they discovered petsc-3.1's current limitations.
