Apologies for the delay on this - a belated summary on software
and code for 2D Fourier Projection and 2D Patterson Projection.

Jon Wright noted via E-mail that the CCSL (Cambridge Crystallography 
Subroutine Library) has this functionality via Fortran code.

"The Cambridge Crystallography Subroutine Library is a collection of 
many Fortran routines which will allow you to tailor your own application 
to do just about everything in crystallography."

>Snipped from the source is the following comment:
