BGI (Basic Graphical Instructions) to PostScript translator. Probablynot useful outside the Computer Centers. Added code to tie lines todevice space coordinates. Helps eliminate variations in line widthsnoticeable when users selected a non-zero linewidth with the -w option. Much that was omitted from early versions of the program has beenimplemented. What's in place will handle most STARE (black and white)and PRISM (color) BGI jobs. PRISM jobs often fill regions with color,and need require device specific tuning to get things just right. Aneasy solution is add "-P/prism true def" option to the postbgi commandline when you translate PRISM jobs. A typical command line for STARE jobs would be, 	postbgi file >file.ps while for PRISM jobs use, 	postbgi -P"/prism true def" file >file.ps
