static function DrawGizmo (gizmo : GizmoType, drawnGizmoType : Type) : DrawGizmo

Description

Same as above. drawnGizmoType determines of what type the object we are drawing the gizmo of has to be.

If drawnGizmoType is null, the type will be determined from the first parameter of the draw gizmo method.
