Hmm. The question to my mind is whether people would expect a simple north to give them which direction north is? Also is it actually relevant whether they find north from a magnetometer or some other method? I wonder if we want to make these some sort of north referenced rotation? in_rot_from_true_north_raw in_rot_from_magnetic_north_raw Technically it is possible to get some direction information from some GPS receivers or to to maintain a knowledge of its location with good gyroscopes. Ultimately userspace doesn't care about it. When we were using the axial magnetic functions we were measuring the field magnitude in that direction. As I understand it here it is just an angle? J
