For 24bit color, 13. * alignment doesn't matter, and for 8-bit color, alignment to every 14. * fourth pixel is most efficient. 15. * 16. * (c) Copyright 1993 Jon W{tte 17. */ 18. 19. /* 20. * You should really not poke in the structures used by the tty window. 21. * However, since it uses the wRefCon of windows (by calling GetWRefCon 22. * and SetWRefCon) you lose that possibility.
