one more remark,

if we drop EulerAngles then we can also drop the AngleAxis class in favor of 
just "rotation" functions, not classes. so the above snippet becomes

Matrix3f m2 = Matrix3f::rotation(a1, Vector3f(1,0,0))
              * Matrix3f::rotation(a2, Vector3f(0,1,0))
              * Matrix3f::rotation(a3, Vector3f(0,0,1));

I think that's nicer!
