NAME
       MPE_Add_RGB_color -  Adds a color to the colormap given its RGB values

SYNOPSIS
       #include "mpe.h"
       int MPE_Add_RGB_color( graph, red, green, blue, mapping )
       MPE_XGraph graph;
       int red, green, blue;
       MPE_Color *mapping;

INPUT PARAMETERS
       graph  - MPE graphics handle
       red, green, blue
	      - color levels from 0 to 65535

OUTPUT PARAMETER
       mapping
	      - index of the new color

RETURN VALUES
       -1     - maxcolors too large (equal to numcolors)
       MPE_SUCCESS
	      - successful
       mapping
	      - index of the new color

NOTES
       This call adds a color cell to X11''s color table, increments maxcolors
       (the index), and writes it to the mapping parameter.

NOTES FOR FORTRAN INTERFACE
       The Fortran interface to this routine is different from its C  counter‐
       part  and  it has an additional argument, ierr, at the end of the argu‐
       ment list, i.e. the returned function  value  (the  error  code)	 in  C
       interface  is returned as the additional argument in Fortran interface.
       The Fortran interface is invoked with the CALL statement.

       All MPI and MPE objects, MPI_Comm, MPE_XGraph  and  MPE_Color,  are  of
       type INTEGER in Fortran.
