bug#5634: fringe redisplay after scrolling

[Francesc Rocher]

In windows with different face height than the default face, the fringe
is displayed incorrectly after scrolling the window using the mouse
wheel. The attached image shows how the left fringe is incorrectly
updated after scrolling the windows upwards with the mouse wheel. The

face used on that window is defined with a height scale of 0.9.
