[comp.sys.apple2] Hint needed

vulture@pnet51.orb.mn.org (Ron Helwig) (02/18/91)

I need to know how to update a window quickly using the GS toolbox.
What I am trying to do is something akin to page flipping, I would
like to be able to redraw a picture and then flip to it (to prevent
flicker, etc). Any hints?

p.s. I am also interested in Xmas demo easter egg info.
