point - creates graphical primitve of type DOM_POINT

Calling sequence:
point(coords [ , option ])
coords      ---> coords_2d
coords      ---> coords_3d
option      ---> Color = [r, g, b]
coords_2d   ---> x, y
coords_3d   ---> x, y, z

Parameter:
x, y, z   --  real evaluable expressions
r, g, b   --  real evaluable expressions between 0.0 and 1.0

Summary:

point serves for the definition of a two- or threedimensional point, which can
be displayed graphically. By use of this function the simplest structure of a
graphical primitives is created. point can be used to create both two- and
threedimensional points. Hereby x and y respectively x, y and z correspond
to the two- or threedimensional coordinates of the point.  In addition this
point can be coloured by use of the option Color = [r, g, b]. The three
parameters r, g and b have to be real values between 0.0 and 1.0.They are
used to describe the amount of red, green and blue of the desired colour.

>>  a := point(0.0, 0.0, 0.0);

      point(0.0, 0.0, 0.0)

>>  b := point(0.0, 1.0, 1.0, Color = [0.0, 1.0, 1.0]);

      point(0.0, 1.0, 1.0, Color = [0.0, 1.0, 1.0])
