Forgive me if I'm totally wrong... I haven't had an Apple in my house since the SE/30, so I'm just drawing on minimal observations. Maybe Photon allows different windows to have different color depths. Then a modified XFree86 would have an easier time doing the same. Aside from Cadence, is there any need for this feature? Allegro and SDL and similar typically provide their own color depth emulation code, and I have written 8bpp-only code that displayed just fine on 32bpp displays and vice versa. (But since it used Allegro the same program worked in MS-DOS, MS-Windows, fbcon, X11, and others...) -- Andy Goth | [EMAIL PROTECTED] | http://ioioio.net/ End communication. _______________________________________________ XFree86 mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xfree86
