For now I don't think you can convert my "Rotoide Prismatic" joint to 
have the same axis (as the joint in a chair).

I needed to have the 2 axis not parallel to split the motion and 
rotation constraints in the function (GetInfo2).

I'm using my joint to simulate a piston with the attachment at the 
bottom included in the joint (like the piston in the suspension of a car).
