code: public ByteBuffer getRotKeyBuffer() {
          ByteBuffer buf = m_rotKeys.duplicate();
          buf.order(ByteOrder.nativeOrder());
          
          return buf;
      }
docs: Returns the buffer with rotation keys of this animation channel.<p>
  
  Rotation keys consist of a time value (double) and a quaternion (4D
  vector of floats), resulting in a total of 24 bytes per entry. The
  buffer contains {@link #getNumRotKeys()} of these entries.<p>
  
  If there are rotation keys, there will also be at least one
  scaling and one position key.
