vec_set(vector_of_copied_speed, my.pan) creates really weird values, not very usefull ^^

With "speed = abs(my.pan - copy)" I can't get the direction, but its the (only ?) way to calculate the speed. And tilt and roll are again different things, with values that are not only going down and up but that are jumping around.

It's possible to calculate the speed and direction without pan, tilt and roll ? Cause these properties are behaving very unhandy.
