Remove workaround for drawing the rotation gizmo

Since [0], transform gizmos are no longer hidden during transform.

The same can be observed for rotation gizmos.

However, as a workaround for these rotation gizmos, there was already a
drawing utility running.

With the gizmo and the utility this drawing is now being done twice.

So remove the utility/workaround and update the gizmo accordingly.
