I thought one of good things about your patch is to make scrolling smooth
without changing default.  No?

A buffer with images has lines with different height.
I think lineHeight should be
 - height of 1 line (or sum of 5 lines) at the top on a screen
   when scrolling up
 - height of unseen 1 line (or sum of unseen 5 lines) above the
   top out of screen when scrolling down.
