 Keypoint data, commonly used for human pose estimation. A keypoint capture is associated to a template that defines the keypoints (see annotation.definition file).
 Each keypoint record maps a tuple of (instance, label) to template, pose, and an array of keypoints. A keypoint will exist in this record for each keypoint defined in the template file.
-If a given keypoint doesn't exist in the labeled gameobject, then that keypoint will have a state value of 0; if it does exist then it will have a keypoint value of 1.
+If a given keypoint doesn't exist in the labeled gameobject, then that keypoint will have a state value of 0; if it does exist then it will have a keypoint value of 2.
 ```
 keypoints {
   label_id:      <int>   -- Integer identifier of the label
       index:     <int>   -- Index of keypoint in template
       x:         <float> -- X pixel coordinate of keypoint
       y:         <float> -- Y pixel coordinate of keypoint
-      state:     <int>   -- 0: keypoint does not exist, 1 keypoint exists
+      state:     <int>   -- 0: keypoint does not exist, 2 keypoint exists
     }, ...
   ]
