 Now, why doesn't dragging work?  I'm sure that's what
most people mean
 when they refer to pixel-based scrolling.  Having scrollbar *buttons*
 scroll pixel by pixel is pretty useless. 
Because the pixel based scrolling works by applying a heuristic in
window_scroll. Dragging the scrollbar however  calls set-window-start
directly. Somebody needs to implement a similar heuristic in
scrollbar-vertical-drag.
