*
* - Pose is the local (object level) component of armature. The current
* object pose is saved in files, and (will be) is presorted for dependency
* - Actions have fewer (or other) channels, and write data to a Pose
* - Currently ob->pose data is controlled in BKE_pose_where_is only. The (recalc)
* event system takes care of calling that
* - The NLA system (here too) uses Poses as interpolation format for Actions
* - Therefore we assume poses to be static, and duplicates of poses have channels in
