593	psProject / psDeproject	eugene	David.Robbins@…	"psProject and psDeproject are inefficiently implemented, and can have
out-of-range errors.  these functions calculate phi and theta via, eg, atan of a
polynomial combination of the input angles, then calculate their sines and
cosines.  this is better done by writing the sines and cosines directly as
combinations of the arguments used to calculate the atan.  I am attaching
example code which calculates the projections this way, but is not very PS-lib
compliant."	defect	closed	high		astro	0.8.0	minor	fixed		robert.desonia@…
