This will try to build or use a GL display list, if it can; the display list ID is returned (-1 if there is none), and should be saved and passed in the next time the element is set. The node calling this routine is responsible for calling glDeleteLists to free up the display list at the right time.

		int	nc,
		const unsigned char *	bytes,
