Well, it is not all.  I don't like that the thumb shrinks for "normal" 
scrolling, i.e. not overscrolling.  As far as I know, no other program 
has overscrolling, so the common behaviour is undefined.  I do not 
agree that it is the desired behaviour.  If the window size and the 
buffer size are the same, and if the mouse pointer starts the scroll in 
the same position, then the same amount of movement should give the 
same amount of lines scrolled regardless if this is a normalscroll or 
an overscroll.  But as I said, there are no programs I know of that has 
overscrolling, so this is just an opinion.
