 for other usage Rotation2D and Quaternion are the representations of choice as they are
 more compact, fast and stable. AngleAxis are only useful to create other rotation objects.

 To some extent, Eigen's \ref Geometry_Module "geometry module" allows you to write
 generic algorithms working on both 2D and 3D rotations of any of the five above types.

 actually represented by displacement vector from the origine (pt \~ pt-0). With that in mind,
 real points and vector distinguish when the rotation is applied.
