 *  Description:
 *  -----------
 *  This function determines whether a display is HIGH, MEDIUM, or
 *  LOW display resolution.
 *
 *  Inputs:
 *  -------
 *  Pointer to the DISPLAY and a screen number
 *
 *  Outputs:
 *  -------
 *  One of four types of resolution:  HIGH_RES_DISPLAY, 
 *				      MED_RES_DISPLAY,
 *				      LOW_RES_DISPLAY,
 *				      NO_RES_DISPLAY (if below min for LOW) 
 * 
 *  Comments:
 *  --------
 *  Algorithm only uses XWidthOfScreen to make the determination.
