PointerCoords stores its values as float and its Parcel should do the same. Wrong behaviour may be noticed when MotionEvent is injected using Instrumentation method sendPointerSync. All its PointerCoords values(size, orientation, pressure, etc) will be casted to integer omitting their decimal part. This fix addresses this issue.
