/* r1_sub.c
 *
 * By Byron C. Darrah
 * 10-May-1994, Tuesday
 *
 * This is a short program for testing the system-dependent
 * display_list routines.  It substitues itself for render1 (hence the
 * name, r1_sub) by calling the display routines directly.
 *
 * If the test is successfull, r1_sub will display a blue rectangle on
 * top of a red diamond.
