Excerpts from my comment: "[Alexey's solution] is clearly my preferred approach for this problem. Please keep in mind that image processing is applied to many domains where pixel data have arbitrary (or even no) physical units; for these cases M's implementation is the most appropriate; [the current issue] is nearly marginal, and M9 allows for an elegant workaround."
