Sketches have a setOpacity method. There is now an opacity test in the animation tests page. There is an unfinished rotation function that is commented out in the sketch widget.
Sketches can now include a wedge object type. A wedge takes a position, length, width, and angle. Wedges have been added to some of the sketches in the animation tests.
