I have fixed the problems between ZWEI and the new screen stuff, except:

1) I haven't got around to C-X 2 yet.
2) C-X M still makes a window with its own box.  It ought not to.

I have made ZWEI windows blt back their old contents unless they have
at least DIS-TEXT worth of redisplay to do anyway.  This makes a big
improvement now with controlled swapping.
