} gesture_rotate_t;

Data:

gesture_base_t base: The gesture base data structure.
rotate_params_t params: The swipe parameters.
gesture_coords_t coords[2]: 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.
int last_angle: The previous angle.
