Yuval Tassa 2b192cebb6 PUBLIC: In mju_normalize4, don't normalize if norm is less than mjMINVAL away from 1.
This makes mj_forward calls idempotent if warmstart is disabled and quats in qpos are normalized.

Yuval Tassa 7542c90cd2 Improved behaviour of mouse-spring interactions.
Also:

- Renamed recently introduced `mjvPerturb` member `reflocalpos` -> `refselpos` and corrected docstring.
- Added `mjvPerturb.localmass`: body spatial inertia at selection point.
- Removed `const` qualifier to `mjData` argument of `mjv_initPerturb()`, to facilitate spatial inertia computation.
- Improved `mj_Object{Velocity, Acceleration}` docstrings, clarifying that rotational velocities precede linear velocities.
- Removed redundant const qualifiers from non pointer arguments to `mju_dot` and `mju_writeNumBytes`.
