- The coordinates of the touch events for the two fingers.
- gesture_coords_t centroid
- The coordintes of the midpoint between the two touches.
- gesture_coords_t last_centroid
- The coordintes of the midpoint between the previous two touches.
- int angle
- The angle of the current two touches relative to the x axis.
