GUI: Change value by one on mouse wheel, not by one pixel
On file-grained sliders, changing the value by one pixel was
unpredictable because it wouldn't change by the same amount every
time. (And of course, some values were not possible to set.)
On course-grained sliders, changing the value by one pixel would
sometimes not change it at all, causing the slider to seem stuck.
Now the slider can be set to any value.
