DescriptionThis script draws a star.
Star(float X, float Y, float rin, float rout, int points [, string style ])
X: abscissa of center.
Y: ordinate of center.
rin: internal radius.
rout: external radius.
points: number of points that the star is composed of.
style: style of rendering, the same as for Rect(): D, F or FD.
Note: if rin=rout, the star will appear as a simple circle.
