Creates red and green pens.
Creates seven points to define the curve.
Draws seven red straight lines between the seven points to form a polygon.
Creates tension and fill mode settings.

Remarks
This method draws a closed cardinal spline that passes through each point in the array. If the last point does not match the first point, an additional curve segment is added from the last point to the first point to close it.
The array of points must contain at least four PointF structures.
The tension
parameter determines the shape of the spline. If the value of the tension
parameter is 0.0F, this method draws straight line segments to connect the points. Usually, the tension
parameter is less than or equal to 1.0F. Values over 1.0F produce unusual results.
