        - move pointer from frame to page here from WebKit

        * WebCore.xcodeproj/project.pbxproj: Added PageMac.h.

        * bridge/mac/PageMac.h: Added.

        * bridge/mac/MacFrame.h: Added a page parameter to the constructor.
        * bridge/mac/MacFrame.mm:
        (WebCore::MacFrame::MacFrame): Pass the page and renderer to the Frame constructor.
        Moved the call to Cache::init up into Frame, and got rid of the call to Frame::init
        since that's now handled by the constructor. Also put the code to create the
        browser extension object here.
        (WebCore::MacFrame::submitForm): Update for new method name.
        (WebCore::MacFrame::createFrame): Ditto.
        (WebCore::MacFrame::sendContextMenuEvent): Update since m_doc is a RefPtr.

        * bridge/mac/WebCoreFrameBridge.h: Changed parameters on init methods. Renamed
        the part method to impl. Added a page method.
        * bridge/mac/WebCoreFrameBridge.mm:
        (frameHasSelection): Change use of part method to impl.
        (-[WebCoreFrameBridge appendChild:]): Use m_frame directly instead of calling part method.
        (-[WebCoreFrameBridge removeChild:]): Ditto.
        (-[WebCoreFrameBridge initMainFrameWithPage:]): Added. Now does the first-time initialization
        only here and create a frame for a main frame.
        (-[WebCoreFrameBridge initSubframeWithRenderer:]): Added. Doesn't do the first-time initialization
        and creates a frame for a subframe.
        (-[WebCoreFrameBridge page]): Added.
        (-[WebCoreFrameBridge setOpener:]): Change to use impl method instead of part.
        (-[WebCoreFrameBridge executionContextForView:]): Ditto.
        (-[WebCoreFrameBridge impl]): Added.

        * bridge/mac/WebCorePageBridge.h: Removed init method and added setMainFrame: method and impl method.
        * bridge/mac/WebCorePageBridge.mm:
        (-[WebCorePageBridge init]): Changed to create a PageMac.
        (-[WebCorePageBridge setMainFrame:]): Added.
        (-[WebCorePageBridge impl]): Added.

        * bridge/mac/BrowserExtensionMac.mm:
        (WebCore::BrowserExtensionMac::createNewWindow):
        * kwq/KWQAccObject.mm:
        (-[KWQAccObject rendererForView:]):
        * kwq/KWQComboBox.mm:
        (-[KWQPopUpButtonCell trackMouse:inRect:ofView:untilMouseUp:]):
        * kwq/KWQFileButton.mm:
        (KWQFileButton::focusPolicy):
        * kwq/KWQSlider.mm:
        (QSlider::focusPolicy):
        * kwq/KWQTextArea.mm:
        (-[KWQTextAreaTextView _isResizableByUser]):
        (-[KWQTextAreaTextView _trackResizeFromMouseDown:]):
        Change methods to get from bridge back to objects to be named "impl".
        The old one was named "part".

        * page/Frame.h: Added Page and RenderPart parameter to constructor.
        Added a page function. Removed the createBrowserExtension function.
        * page/Frame.cpp:
        (WebCore::parentFromOwnerRenderer): Added. Helper for constructor.
        (WebCore::Frame::Frame): Moved all the code from init into here. Also change
        to set the parent right from the start.
        (WebCore::Frame::stopLoading): Change since m_doc is now a RefPtr.
        (WebCore::Frame::clear): Ditto.
        (WebCore::Frame::document): Ditto.
        (WebCore::Frame::setDocument): Ditto.
        (WebCore::Frame::begin): Ditto.
        (WebCore::Frame::gotoAnchor): Ditto.
        (WebCore::Frame::typingStyle): Change since m_typingStyle is now a RefPtr.
        (WebCore::Frame::setTypingStyle): Ditto.
        (WebCore::Frame::clearTypingStyle): Ditto.
        (WebCore::Frame::isFrameSet): Change since m_doc is now a RefPtr.
        (WebCore::Frame::page): Added.

        * page/FramePrivate.h: Changed initialization to use member-initialization
        syntax. Removed unused m_frames. Changed m_doc and m_typingStyle to use
        RefPtr. Added an m_frame.

        * page/Page.h: Made destructor virtual so we could have a Mac derived class.
        Added a setMainFrame function and removed the mainFrame parameter from the constructor.
        * page/Page.cpp:
        (WebCore::Page::Page): Removed the mainFrame parameter.
        (WebCore::Page::setMainFrame): Added.

        - move pointer from frame to page over to WebCore

        * WebCoreSupport/WebPageBridge.m: (-[WebPageBridge initWithMainFrameName:webView:frameView:]):
        Call super init to create the page before creating the main frame and calling setMainFrame: with it.

        * WebCoreSupport/WebFrameBridge.h: Remove page pointer, and change init function parameters.
        * WebCoreSupport/WebFrameBridge.m:
        (-[WebFrameBridge initMainFrameWithPage:frameName:view:]): New function that is used only for
        the main frame. Passes the page over to the other side of the bridge.
        (-[WebFrameBridge initSubframeWithRenderer:frameName:view:]): New function that is used only for
        subframes. Passes the renderer over to the other side of the bridge.
