In order to make slow inner-frame scrolls faster, we want to use ewk_view_scroll() [0] to handle slow scrolls. It basically adds the scroll request to a scroll-requests array that is latter processed by _ewk_view_single_scroll_process_single() [1], which analyzes the scroll direction and offset (using the information provided through scrollDelta) and move the backing-store contents that are still going to be visible in the scrolled direction, so we're left with a smaller area to repaint.
