When using AIS_AnimationObject, linear interpolation is performed from one gp_Trsf transformation to another. But when an object rotates around a specific axis, the object moves not along a linear trajectory, but along a circle. Therefore, a separate class AIS_AnimationAxisRotation was created that allows to animate rotation around a specific axis. Test case tests/v3d/bugs/bug32570 was added.
