Description of modifications made to r3.showdspf directory during conversion of code from IrisGL (running only on SGI workstations) to OpenGL (running on any OpenGL-capable UNIX workstation)

The following files were changed (and perhaps renamed during conversion)
`do_color.c -> do_color_ogl.c
draw_cap.c -> draw_cap_ogl.c
draw_polys.c -> draw_polys_ogl.c
draw_cappolys.c -> draw_cappolys_ogl.c
main.c -> main_ogl.c
init_caps.c -> init_caps.c
vizual.h -> vizual.h
Gmakefile -> Gmakefile
`
The following files are new files
`new_init_graphics.c
kns_defines.h
kns_globals.h
togif.c
togif.h
`
The following files are unchanged:
`cap_data.c
init_caps.c
debugf.c
thresh_array.c
make_header.c
r3_data.c
r3_find.c
`
The following files removed since they were made unnecessary
`init_graphics.c
dump_rect.c -> functions moved to new_init_graphics.c
` axes2.c
*** Disclaimer ***
The porting effort from IrisGL to OpenGL was performed with the goal of just getting things to run with OpenGL with some user-interface improvements. Only a small attempt was made to correct for sloppy/dangerous coding practices found in the original code. Sloppy/dangerous coding practices were modified only when they resulted in serious code errors (causing core dumps). Certain files, such as new_init_graphics.c, which were totally new files, were coded to higher standards. In general, this effort was only a porting effort, not a re-architecting effort.
