/*
* Name:
* grf_3.2.c
* Purpose:
* Implement the grf module required by AST V3.2 if no graphics system
* is available.
* Description:
* This file implements the low level graphics functions required
* by the rest of AST V3.2, except for those already defined in
* grf_2.0.c (i.e. those needed by AST V2.0). These implementations
* simply report an error when called.
* Inheritance:
* This module is not a class and does not inherit.
