                //     system where (0,0) is at the top/left of the object bounding box and (1,1) is
                //     at the bottom/right of the object bounding box). When the object's bounding
                //     box is not square, the gradient normal which is initially perpendicular to
                //     the gradient vector within object bounding box space may render
                //     non-perpendicular relative to the gradient vector in user space. If the
                //     gradient vector is parallel to one of the axes of the bounding box, the
                //     gradient normal will remain perpendicular. This transformation is due to

                //     to user space.

                // which is an extremely long and confusing way to tell what I just said above.
