  procedure ogCubicBezierCurve(x1, y1, x2, y2, x3, y3, x4, y4:int32; 
                                segments : uInt32; colour:uInt32);

Draws a cubic Bezier curve based on the coordinates (x1,y1),(x2,y2), (x3,y3),(x4,y4).

Segments is the number of line segments to use between points. The higher the number the smoother the line, but the longer it takes to render.
