I was thinking of the set of solutions that satisfy a tangential line to the
point <-5,0,0> (assumed), but include the camera position. This set would be
null in that it cannot be satisfied from the current camera location, except
in orthographic projection (I think).

Perspective magnification, spherical aberration,....? Stymied...

Thanks for being agreeable. :)
