(They sometimes differ in how they interpret coordinates -- whether measured from the center or the top-left of one of the images.)  Since the disappearance of pinholes, the "scene" datatype doesn't serve much purpose any more.  Would it make sense to use a consistent and compositional naming scheme, e.g. add-line/crop, add-curve/crop, etc?
