/* *********************** NOTE ON POSE AND ACTION **********************
- 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 where_is_pose 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
same order, for quick interpolation reasons
