    It confuses me quite a bit.  Is there no way to make the thumb extend
    to the bottom of the scrollbar area when end of buffer is visible, and
    yet to also allow scrolling further down so that the last line of the
    buffer can be moved to the top of the window?

Perhaps we could have the thumb "move off the bottom" of the scroll bar,
so that when ZV is at the top of the screen, the thumb is almost invisible.
I don't know whether this would be convenient to use; perhaps that
depends on many little details of the UI of the scroll bar.
For xterm-style mouse-2, it would be convenient if it grabbed the mouse
so that you could easily scroll the thumb beyond the bottom by moving
the mouse beyond the bottom.

It does depend on the UI details. It could be done by grabbing the mouse (assuming you can know when to do this), but what about clicking on the arrows (line down) or the trough (page down)? Then one would have to translate coordinates to match with the scroll bar window parts and other difficult things. Its almost reimplementing the whole scroll bar logic without having the benefit of the scroll bars internal data (size and position of arrows for example).
