Hi posn-s of graphics/graphics are structs with two reals. They are used to locate objects in a viewport. I would expect locations to be identified by two exact nonnegative integers pointing to a pixel. We don't have fractions of pixels, do we? Where for example is (make-posn 3.4 5.6)? Does it identify the same position as (make-posn 3 6)? Maybe there is a reason posn has reals, but I do not see why. If there is such a reason, please tell me.
