Thank you very very much for working on this.

So I've tried out your patch and I have to say, I'm impressed. The new 
behavior is pretty much perfect.
I even find the overscrolling behavior and the resizing of the 
scrollbar at the end of a buffer very
tolerable - it's not resizing erratically, and most importantly, it 
doesn't jump when you grab the
scrollbar.

I can confirm, the screen updates lag behind a bit on my 2002 Powerbook.

There is no method to not display the point in the visible area? I'd 
like to scroll somewhere else in the
buffer (and I do that quite often) and then jump back, and I know a lot 
of other people are used to that,
too. Such a setting would, of course, preserve the region when 
scrolling.
