            Changing cursor style has no effect until the mouse moves
            https://bugs.webkit.org/show_bug.cgi?id=14344
            rdar://problem/7563712
    
            No tests added because we don't have infrastructure for testing actual cursor
            changes (as opposed to cursor style computation) at this time. We might add it later.
    
            * page/EventHandler.cpp:
            (WebCore::EventHandler::dispatchFakeMouseMoveEventSoon): Added.
            * page/EventHandler.h: Ditto.
    
            * rendering/RenderObject.cpp:
            (WebCore::areNonIdenticalCursorListsEqual): Added.
            (WebCore::areCursorsEqual): Added.
            (WebCore::RenderObject::styleDidChange): Call dispatchFakeMouseMoveEventSoon if
            cursor styles changed.
