Some devices provide what are termed precise scrolling deltas and generate a far greater number of scrolling events.  The trackpad is such a device.  Cocoa events have a hasPreciseScrollingDeltas method that will provide this information.  It is used in wxWidgets window.mm, for instance, when translating NSEvents to wx events.
