feat(editor): track gizmo rings along the track: direction, grade and cant

Browse Source 
The rotate gizmo stands along the track. The cross ring changes the grade about the middle or the selected
end, the joined tracks take the grade at the joints; the ring along the track changes the cant of the track
or of the selected end, the joined tracks take it at the joints and ramp it. On a control vector the cross
ring tilts it up or down. Ctrl steps by 5 degrees, 1 per mille, 5 mm.
