```javascript
this.matrix.multiplySelf( matrix );
```

I don't think that works like that. Got the feature to work by multiplying the other way around (like in `updateMatrixWorld()`).

I've tested the code a bit and seems to work, but the rotations aren't right when you rotate more than one axis. `getRotationFromMatrix()` may need some work.
