The same functon exist in 2.x in osg::Camera, but this still doesn't
change the fact that doing freeform user interaction in orthographic
projection is not reasonable goal or expectation, the projection
simply doesn't work for this.

Othrogrphics views are best reserved for map, side and oblique views
such as you'd find in technical drawings on building, or head up
