add support for angular velocity and acceleration

[roshanch]

modifying API to receive angular velocity and acceleration. None of the demos are using onContollerEvent API. Open to suggestions for testing.

The onControllerEvent was added in https://github.com/Samsung/GearVRf/pull/1254. You can see the issue it was in response to and additional information. It was an enhancement for a user. You might add something to gvr-controller.

I believe we need to switch to custom events in GVRGearCursorController. They may also wrap the MotionEvents from GVRCursorController for the convenience of clients like the GVRViewSO. Probably oversimplifying it but a MotionEvent cannot carry all the information we need. So we have the onContollerEvent hack.

Sounds good to me. Can we subclass MotionEvent?

[liaxim]

No, it is a final class.

added sample code for controllerEvent in gvr-controller, was able to retrieve angular velocity but the acceleration is coming 0 from platform library. Moiz is going to check with HQ.

        mActivity.getEventReceiver().addListener(new GVREventListeners.ActivityEvents() {
            @Override
            public void onControllerEvent(Vector3f position, Quaternionf orientation, android.graphics.PointF touchpadPoint, boolean touched, Vector3f angularAcceleration,
                                          Vector3f angularVelocity) {
                Log.e("TAG", ">> onControllerEvent: position " + position);
                Log.e("TAG", "<< onControllerEvent: orientation " + orientation);
                Log.e("TAG", ">> onControllerEvent: angularAcceleration" + angularAcceleration);
                Log.e("TAG", "<< onControllerEvent:  angularVelocity " + angularVelocity);
            }
        });

Planning to merge on Monday.
