        * accessibility/AXObjectCache.cpp:
        (WebCore::AXObjectCache::AXObjectCache):
        Changed to take a pointer to its owner document. This is used by
        AXObjectCache::handleFocusedUIElementChanged().
        (WebCore::AXObjectCache::focusedUIElementForPage):
        Code moved from AccessibilityRenderObject::focusedUIElement(). Modified
        to be a static function and to take a pointer to a Page.
        (WebCore::AXObjectCache::platformGenerateAXID):
        Moved the code to generate the next AXID from getAXID() to here. Added
        a #if to make this non-WIN only, because Windows has its own
        implementation.
        (WebCore::AXObjectCache::getAXID):
        Ensure that we generate a positive AXID, ranging from 1 to LONG_MAX.

        * accessibility/AXObjectCache.h:
        Add a declaration for Document and Page. Removed the declaration of
        AccessibilityObject, because we include the header. Reordered the
        declaration of Node alphabetically. Moved the typedef for AXID to
        AccessibilityObject. Removed some trailing whitespace. Added a member
        variable to hold a pointer to the owner Document.
        (WebCore::AXObjectCache::AXObjectCache):
        Changed to take a pointer to its owner Document.
        (WebCore::AXObjectCache::focusedUIElementForPage):
        Added; code moved from AccessiblityRenderObject::focusedUIElement().
        Returns the focused element with respect to accessibility.
        (WebCore::AXObjectCache::platformGenerateAXID):
        Declare a function to generate an AXID.
        (WebCore::AXObjectCache::objectFromAXID):
        Return the AccessibilityObject with the given AXID.

        * accessibility/AccessibilityObject.h:
        Moved the typedef for AXID from AXObjectCache to here. Made the m_id
        member use the typedef.
        (WebCore::AccessibilityObject::axObjectID):
        Changed the return type to use the typedef.
        (WebCore::AccessibilityObject::setAXObjectID):
        Changed the argument type to use the typedef.

        * accessibility/AccessibilityRenderObject.cpp:
        Removed some unneeded #includes.
        (WebCore::AccessibilityRenderObject::focusedUIElement):
        Moved the code to AXObjectCache::focusedUIElementForPage(), which we now
        call.

        * accessibility/win/AXObjectCacheWin.cpp:
        (WebCore::AXObjectCache::platformGenerateAXID):
        Ensure that we generate an AXID that is in the range 1 to LONG_MAX.
        (WebCore::AXObjectCache::handleFocusedUIElementChanged):
        If the Document has no Page, return. If the Page has not focused
        element (respecting accessibility), return. Assert that the
        accessibility of the focused element is not ignored, and that the
        object's AXID will be negative and fit into a LONG when negated.
        Broadcast a focus event for the object.

        * dom/Document.cpp:
        (WebCore::Document::axObjectCache):
        Pass this when creating the AXObjectCache.
        (WebCore::Document::setFocusedNode):
        Call AXObjectCache::handleFocusedUIElementChanged() on Windows.

        * AccessibleBase.cpp:

        If the child ID is negative, negate it and treat it as an AXID.
