A class to draw Bezier curves.
This class allows to draw Bezier curves defined by an arbitrary number of control points. Bezier curves are named after their inventor, Dr. Pierre Bezier. He was an engineer with the Renault car company and set out in the early 1960's to develop a curve formulation which would lend itself to shape design. Bezier curves are widely used in computer graphics to model smooth curves. A Bezier curve is completely contained in the convex hull of its control points and passes through its first and last control points. The curve is also always tangent to the first and last convex hull polygon segments. In addition, the curve shape tends to follow the polygon shape.
