DESCRIPTION:macro definition for relative position to global position.
CONTENTS: REL_POS( orient_R, globalY_R, globalX_R,
relativeX_R, relativeY_R, cellX_R, cellY_R ) ;
INT orient_R, globalY_R, globalX_R, relativeX_R,
relativeY_R, cellX_R, cellY_R ;
DATE: Jun 30, 1988
REVISIONS: Aug 13, 1990 - moved to library for MC.
Thu Feb 7 00:04:51 EST 1991 - now correctly handle
the truncated center regardless of orientation
with the addtion of the REL_POST MACROs.

/* -----------------------------------------------------------------
The following is a macro which calculates the global pin position
given an orientation, a cell center ( global position ) and the
pin position relative to the cell center. The macro was designed
for speed. For test purposes, the macro can be short circuited,
and instead call a the rel_pos function - defined in output.c
The _R is an attempt to avoid variable substition problems.
