Controls whether this shape is drawn individually when the world is drawn.
The shape is only drawn when the world draw options include PhysicsWorld.DrawOptions.SelectedShapes or PhysicsWorld.DrawOptions.SelectedShapeBounds; changing the draw options never changes this state. The state persists until set to false, the shape is destroyed, or PhysicsWorld.ClearDrawSelected clears the whole world. The shape must also have PhysicsShape.worldDrawing enabled to be drawn.
