scalebutton: Invert smooth scroll dy when adding to the current value

Browse Source 
On regular scrolling (ie. not natural scrolling), positive deltas in the
Y axis (downwards) should actually move the value towards the adjustment
minimum value to be more intuitive. This also makes the scrolling
directions match between the button and the popped up scale.
