points are drawn with the current color and linewidth. Points are currently device-specific and may appear as circles, squares, or not at all; as they are generated by a zero-length vector using the hardware line style.
Draw a point at x, y, z
Fortran: subroutine point(x, y, z) real x, y, z C: vogle_point(x, y, z) real x, y, z; Pascal: procedure Point(x, y, z: real)
Draw a point at x, y.
Fortran: subroutine point2(x, y) real x, y C: vogle_point2(x, y) float x, y; Pascal: procedure Point2(x, y: real)
