- </FONT>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 <B>original</B> 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, <B>not</B> a re-architecting
- effort.<BR>
