As far as I can tell +inv is not a valid argument.  It just gets passed to the projection initialization
routine which then ignores it.  The -I flag is still the correct way to tell "proj" program to do an inverse
projection.

Programmatically, you must use pj_inv to do an inverse projection (or use pj_transform).
