checking in first phase of new hit detection algo, which enables high performance event detections even if there are hundreds of thousands of shapes. This is a giant improvement over the previous algo, and is a fairly big architectural change. Since the Animation architecture and API is also changing, I feel that these changes are big enough to warrant a new major version, v4.0.0
