|    alan morse        11 sep 84    Extracted from dvprim.h
|    russell turner    3  jan 89    added primitive GRreset
|    chris hoffmann     26 nov 90       added mask and mass pixel setting
|                                       for rasters
|    chris hoffmann     10 oct 91       Added pixrep extensions to rasters.

|    Description
|    This contains the indices into the link tables for the GR
|    graphics routines.  This include file should only be used
|    by GR routines and their device drivers.
|
|    Note that primitives added after 1988 (i.e. 56 and beyond)
|    must check for a NULL function pointer in the table before calling
|    to be upwardly compatible with older, 'pre-89' drivers. -rt

| define the symbolic names of the device-dependent primitive functions
|
|    Every device supported by the system has a corresponding device
|    module of support routines.  Each module contains a table of
|    pointers.  Each pointer within the table points to a device-
|    dependent support function.  The generic primitive module that
|    'sits' between higher level software and the device-dependent
|    modules links to the device-dependent support functions through
|    these function pointer tables.
|
|    The following definitions actually define the index positions
|    of the function pointers within each function pointer table.
|    The generic primitive module uses these index definitions to
|    access device-dependent primitive functions.
|
|    FI means "Function Index"
