NAME
        GfxAssociate -- associate a graphics extended node with a given pointer
                        (V36)

   SYNOPSIS
       GfxAssociate(pointer, node);
                    A0       A1

        void GfxAssociate(VOID *, struct extendednode *);

   FUNCTION
        Associate a special graphics extended data structure (each of which
        begins with an extendednode structure)  with another structure via
        the other structure's pointer. Later, when you call GfxLookUp()
        with the other structure's pointer you may retrieve a pointer
        to this special graphics extended data structure, if it is
        available.

   INPUTS
        pointer = a pointer to a data structure.
        node = an extendednode structure to associate with the pointer

   RESULT
        an association is created between the pointer and the node such
        that given the pointer the node can be retrieved via GfxLookUp().
