Reviewed by Sam Weinig.
Source/WebCore:
This patch adds 4 new events called webkitwillrevealbottom, webkitwillrevealtop,
webkitwillrevealleft, and webkitwillrevealright. These events will fire when the
user has scrolled close to corresponding edge of the document. Right now that is
defined to be one viewport away from the corresponding edge.
FrameView::scrollPositionChanged() and
FrameView::scrollPositionChangedViaPlatformWidget() now take two parameters
representing the old scroll position and the new position.
* WebCore.exp.in:
New events.

(WebCore::FrameView::scrollPositionChangedViaPlatformWidget):
After sending scroll events, also call sendWillRevealEdgeEventsIfNeeded() to send
the see if we should send the new will-reveal events.
(WebCore::FrameView::scrollPositionChanged):
Use the old position and the new position to determine if the events should be
sent.
