Examples of org.apache.flex.swf.types.CurvedEdgeRecord

org.apache.flex.swf.types.CurvedEdgeRecord
The curved-edge record stores the edge as two X-Y deltas. The three points that define the Quadratic Bezier are calculated like this:
1. The first anchor point is the current drawing position.
2. The control point is the current drawing position + ControlDelta.
3. The last anchor point is the current drawing position + ControlDelta + AnchorDelta.
The last anchor point becomes the current drawing position.
