We should not recenter the display in any case where the start is not
forced and point is not moved.

That's not a problem, as `mouse-yank-primary' and friends already call
mouse-set-point.
WDYT about the attached patch? It recenters the display whenever PT !=
w->last_point, and it seems to work very well.
It also introduces a new variable `scroll-move-point' that controls if
the scrolling commands will try to move point to stay visible.
