* Name:
* grf_2.0.c
* Purpose:
* Implement the grf module required by AST V2.0 if no graphics system
* is available.
* Description:
* This file implements the low level graphics functions required
* by the rest of AST V2.0, by reporting errors when called.
* Inheritance:
* This module is not a class and does not inherit.
