Curve

Draw a curve in the current line style from the current drawing position to the destination location. The curve drawn is a quadratic Bezier curve that uses a single control point to specify the weighting of the curve. A control point close to the line made by the current position and the destination position means a gentle curve in the direction of the control point. As the control point moves from the line the curve will get more exaggerated and acute. Most authoring packages use cubic Bezier curves which allows greater control over the curves but these can all be approximated by quadratic curves. As an alternative to specifying a control point the reflection of a control point used in a previous curve can be used to allow for continuous smooth curves.
