According to spec, https://www.w3.org/TR/css-scroll-snap-1/#snap-scope
we should only consider the snap points of visible snap areas.
This patch implements the visibility requirement by adding a field of
visible region for each snap point. It also handles the case of
visibility conflict when snapping to two axes individually.
