Title: .min_point() and .max_point() for Arc and BezierCurve

Creates bounding boxes drawn in tight to include only the points that are drawn by the respective shapes.

Pay special attention to assumptions in Arc, the upverter format spec wasn't especially clear so I just went for an informed guess.
