What is a quadratic bezier curve?
Quadratic bezier curves are curves described by two endpoints and a control point. They are the curves that are used in the Flash drawing API (unlike other drawing applications, which may use cubic bezier curves, described by two endpoints and two control points). A single curve segment is defined by an initial “moveTo” point, a final “curveTo” endpoint, and a control point which defines the shape of the curve. Each additional curve segment in the same shape is defined by its own endpoint and its own control point.
