 // Wheel events come in two flavors:
 // The ScrollByPixelWheelEvent is a fine-grained event that specifies the precise number of pixels to scroll. It is sent directly by MacBook touchpads on OS X,
 // and synthesized in other cases where platforms generate line-by-line scrolling events.
 // The ScrollByPageWheelEvent indicates that the wheel event should scroll an entire page. In this case WebCore's built in paging behavior is used to page
 // up and down (you get the same behavior as if the user was clicking in a scrollbar track to page up or page down).
