| The gizmo showing the rotation of the camera differs from other |
| gizmos by the fact that it doesn't overlay the camera in the |
| scene, but rather stays in a corner of the view. Still, the |
| perspective of the gizmo should reflect the perspective as if |
| it was located on the same spot as the camera. For that reason, we |
| draw it in a separate View3D, which means that the user can position |
| it wherever he wants on the screen without affecting how it looks. |
