330	psSphereGetOffset in linear mode	Eric.VanAlst@…	eugene	"The current implementation assumes the first position specified is spherical and
used for the projection center and the second position is on the local tangent
plane.  The function psDeproject is then used to deproject the second position
to a spherical coordinate which is the offset from the projection center.  Is
this the correct implementation since the SDR and ADD do not specify?"	defect	closed	normal		PSLib SDRS	unspecified	normal	fixed
