ScrollUnit

Specifies the unit of scroll deltas.

When you get %GDK_SCROLL_UNIT_WHEEL, a delta of 1.0 means 1 wheel detent click in the south direction, 2.0 means 2 wheel detent clicks in the south direction... This is the same logic for negative values but in the north direction.

If you get %GDK_SCROLL_UNIT_SURFACE, are managing a scrollable view and get a value of 123, you have to scroll 123 surface logical pixels right if it's
