I'm looking for a simple program which shows how to use pswraps
*outside* of the application kit and Interface Builder.   I understand
how to write postScript code, convert it to C using pswrap, and then
compile and link to form an executable file.  What I don't understand,
however, is how to establish the proper context, which (I guess) 
is a connection between my program and the Display Postscript Interpreter.

For those curious, or skeptical,  I want to do this so that I can
use the entire display, with as little interference and overhead as 
possible, to present full-screen visual stimuli for experiments in 
perceptual psychology.  

A good example of the sort of full-screen use I'm after is in the file

  /NextLibrary/Images/Scene_movies/snake.script.ps

But what I'd like to do is to take that (or similar) postscript code,
pswrap it, and run it from a fast-loading C program, rather than out
of Preview.  Can anyone help me on this?  Thanks.
