    Point3d.transformBy matrix point

is equivalent to

    Point3d (Matrix4.transform matrix (Point3d.coordinates point))

For example:

    point =
        Point3d ( 2, 1, 3 )

    matrix =
        Matrix4.makeTranslate ( 3, 4, 5 )

    Point3d.transformBy matrix point
    --> Point3d ( 5, 5, 8 )

transformBy : Float4x4 -> Point3d -> Point3d
transformBy matrix point =
    Point3d (Matrix4.transform matrix (Point3d.coordinates point))
