View the jsfiddle demonstrating the issue (just click and drag the circle - relevant code on line 102).
When I add a circle to the stage with Pixi.Graphics and drawCircle( 150, 100, 50 ), the circle when dragged becomes offset by it's position ( +150, +100 ) in the Graphics container.
(and if we request the circle.position it's also inaccurate)
What's the best way to add a shape to the screen and set it's position if it's not through a Graphics container?
