        - simplify Mac code for ScrollView, since it's used only for FrameView
          and not in two different modes like it was historically
        - remove code depending on the bridge to get from an NSView to a WebCore::Frame

        * bindings/objc/DOMHTML.mm:
        (-[DOMHTMLInputElement _rectOnScreen]): getDocumentView -> documentView.

        * bridge/jni/jni_jsobject.cpp:
        (createRootObject): Instead of using WebCoreViewFactory to find the frame given
        and NSView, use the WebCoreFrameView interface to do it.

        * editing/mac/EditorMac.mm:
        (WebCore::Editor::paste): getDocumentView -> documentView.
        * editing/mac/SelectionControllerMac.mm:
        (WebCore::SelectionController::notifyAccessibilityForSelectionChange): Ditto.

        * page/FrameView.h: Fixed comment.

        * page/InspectorController.cpp:
        (WebCore::InspectorController::drawNodeHighlight): Removed uneeded typecasts
        to ScrollView* since FrameView is derived from ScrollView.

        * page/mac/EventHandlerMac.mm:
        (WebCore::EventHandler::focusDocumentView): getDocumentView -> documentView.
        * page/mac/FrameMac.mm:
        (WebCore::Frame::imageFromRect): Ditto.
        * page/mac/WebCoreAXObject.mm:
        (-[WebCoreAXObject position]): Ditto.
        (-[WebCoreAXObject doAXTextMarkerForPosition:]): Ditto.
        (-[WebCoreAXObject rendererForView:]): Updated code that used to use
        WebCoreBridgeHolder to use WebCoreFrameView instead.

        * page/mac/WebCoreFrameBridge.mm:
        (-[WebCoreFrameBridge computePageRectsWithPrintWidthScaleFactor:printHeight:]):
        getDocumentView -> documentView.

        * page/mac/WebCoreFrameView.h: Removed the WebCoreScrollbarMode type; we just
        use WebCore::ScrollbarMode directly. Renamed the WebCoreFrameView protocol to
        WebCoreFrameScrollView, since it's a protocol for the scroll view, not the
        frame view itself. Replaced WebCoreBridgeHolder protocol with WebCoreFrameView
        protocol, which returns a WebCore::Frame directly rather than a bridge.

        * page/mac/WebCoreViewFactory.h: Eliminated the bridgeForView method.

        * platform/ScrollView.h: Moved the constructor and destructor out of the
        class-specific #if blocks. Renamed Mac-specific function that gets the
        NSView for from getDocumentView to documentView and a scrollView function
        that returns an appropriately classed NSScrollView.

        * platform/graphics/MediaPlayer.h: Changed type of parentWidget to FrameView
        instead of Widget.
        * platform/graphics/mac/MediaPlayerPrivateQTKit.mm:
        (WebCore::MediaPlayerPrivate::createQTMovieView): Removed unnecessary cast.

        * platform/mac/PopupMenuMac.mm:
        (WebCore::PopupMenu::show): getDocumentView -> documentView.
        * platform/mac/ScrollViewMac.mm:
        (WebCore::ScrollView::ScrollView): Added.
        (WebCore::ScrollView::~ScrollView): Added.
        (WebCore::ScrollView::scrollView): Added.
        (WebCore::ScrollView::visibleWidth): Removed unused non-NSScrollView case.

        * WebCoreSupport/WebFrameLoaderClient.mm:
        (WebFrameLoaderClient::transitionToCommittedForNewPage): Remove incorrect call
        to setView. A couple lines later, there is a call to _install, which sets the
        view to the scroll view.
