260	psDeproject()	gusciora@…	Paul Price	"I'm hoping you can provide an algorithm, or formula. for the Gnomonic and
Orthographic deprojections.  My attempts at deriving them from the information
in the ADD have failed: if I project a spherical coordinate onto a plane, then
deproject that planar coordinate, I don't receive the original spherical
coordinate.  Also, it will be helpful if you point out which greek symbols
correspond to which spherical coordinate members of the psSphere structure;
I think I know, but I'm not 100% sure."	defect	closed	high		PSLib ADD	unspecified	normal	fixed
