coyote: CGPS_SETUP__DEFINE

Description
The purpose of cgPS_SETUP__DEFINE is to define a structure that is
used by cgPS_Open and cgPS_Close to communicate PostScript set-up information
back and forth. The idea is to allow simple and easy set-up of PostScript and
raster file output (though PostScript intermediate files and ImageMagick). The 
program uses a common block named " _$FSC_PS_START_ ".
