        Also, Borrow some of the style change smarts from ApplyStyleCommandImpl to use bold and
        italic tags for applying styles when that is apprpriate. This creates on opportunity to
        factor the code to do this so that this function and the ApplyStyleCommandImpl class can

        3745023 - Safari crashes trying to access anchor while downloading

        I bet this is behind a few other crashers as well.  In this bug the start of the
        download leaves a KWQPageState hanging around, and when that is freed it damages
        the part and view.  If you're still using that page, you're dead.

        The fix is to properly invalidate the PageState when we receive an error before
        reaching WebFrameCommitted state.  Normally this happens when a page is reheated
        from the PageState, but in this case we never manage to leave the page to begin
        with, although we've already created the PageState.

        Other errors besides the synthetic one download generates would have caused similar
        crashing.  Another example would be clicking on a second link before the load
        caused by clicking on the first link reached committed state.

        Since the word containing the current selection is never marked, this does a check to

        Fix for 3752542, stack overflow that crashes Safari at www.dr.dk.  This bug is a regression caused by a fix that
        attempted to repair <caption> behavior to make it behave like Panther.  This fix was incorrect, and in addition
        even our <caption> behavior on Panther was incorrect.

        The patch that fixes this bug also makes <caption> handling work when <caption>s are contained inside a <td>, a <tr>,
        a <th>, or various table section tags (<tbody>, <tfoot>, <thead>).  The <caption> is pulled out and inserted just before
        the relevant ancestor table section.  This behavior matches other browsers.

        Changes to improve our handling of object tags during editing, including

        <rdar://problem/3744533> Problem editing <OBJECT> elements displayed by WebPlugIns 

        Part of the fix for this bug involves removing the close() function from render objects.
        It was decided that this code was no longer needed, as the work it did could be moved
        to other, more modern, places.

        Spellchecking, Part I.  Basic spellcheck is working.  Spelling panel is hooked up.

        At this point, no special marking of misspellings, no grammar check, no context
        menu integration, no "check continually" mode.

        Much of the TextIterator and CharacterIterator interface got published outside

        Currently, the code will allow the selection to be placed in a location that is not

        3705624 REGRESSION: can't rearrange photos on homepage.mac.com album

        A subtle problem stemming from some interaction between focus handing and
        event propagation.  We previously made it so when a focus shift fails we
        don't propagate the event to KHTML.  The fix is to get rid of the inverse
        effect, so now even if a focus shift succeeds, we don't propagate to KHTML if
        the page already canceled default behavior.

        In this specific case, the page is cancelling default behavior since it
        does its own dragging, and the bug was our new system dragging was
        kicking in.

        <rdar://problem/3716479> calling setInnerHTML during a webViewDidChange delegate call causes a crash
        
        The fix involves some rearrangement of code in TypingCommand and TypingCommandImpl.
        Formerly, new TypingCommands would apply themselves (which was a no-op) and then
        do their action in some code a way different than other commands. This type of command
        application is different than for all other commands since TypingCommands can be coalesced.
        The crash occurred as a result of the "no-op" TypingCommand having the unconsidered
        consequence of causing editing delegate notifications to be sent before the command 
        has actually run. This change takes a small step towards making TypingCommandImpl function like
        other commands, where the command work is done in doApply. This makes the notification
        happen in the right order.

        The solution was to revert to the code that was rolled out, and removing

        to ensure the proper construction of well-formed tables (as gross as that

        Fixed several problems with traversal classes. For one, NodeIterators treat
        FILTER_REJECT and FILTER_SKIP the same, since it treats the DOM tree as a
        flat collection of nodes free of hierarchy. The code before this change did
        not do this correctly. It sure pays to go back and read the specs. :)
        
        Also, the code to traverse from node to node when filters were applied was
        not working correctly. My first attemmpt to implement this was just plain
        buggy, as I discovered when I tried to write tests for my WWDC talk. I have
        settled on an implementation which is much simpler and worked for all the
        tests I threw at it.

        Dragging within a web view should be allowed to start when the window isn't key.

        A few months ago, Chris made this work, but it relied on the fact that all dragging
        was done in WebKit.  When WebCore got involved in dragging, it was broken.  Now we
        have a new scheme that gets it working again that properly involves WebCore.

        The general idea is that when AK asks us whether to accept the first mouse and do
        "delayed window ordering", we must consult WC to see if we might start a drag.  In
        addition, instead of these drags in non-active windows being started as a special
        case in WK, they go through the normal WK-WC drag machinery.

        This part fixes the ondragstart coords.  We salt away the window-based mouseDown
        location, since we need that when we dispatch the ondragstart event.  Previously
        we were errantly using a mouseDown point that had already been converted to view
        coords, and then the dispatch converted it again.

        Dragging tweak:  We pass the mouse down coords instead of the
        latest mouse drag coords to the ondragstart event.  This makes it
        easy for the client to figure the correct drag image offset,
        whereas the mouse drag location is next to useless for that.

        Initial work on text truncation.  Working top-down, I think I've made all the changes I will need to bidi.cpp
        and to the block code itself.  The rest of the code can be concentrated in the render_line and render_text files.

        Dashboard wants access to pastboard data during the drag gesture.

        We address this need be allowing docs that are local files to access the
        pasteboard data during a drag, while other pages can only get at the types
        list until the drop happens.  This is deemed safe because local files already
        have such broad super powers.

        Support for DHTML cut/copy/paste.  We now support oncut, oncopy, onpaste.  The events
        are sent to the first node in the selection, or else the body.  Current holes are
        that we do not send events for operations in text fields or text areas (because it
        is hard to get the right hooks into the AppKit).

        We also send onbeforecut, onbeforecopy, onbeforepaste before the other events, which
        isn't really WinIE compatible, but is close.  WinIE uses these to enable cut/paste
        menu items in its UI.  DB doesn't need this for now.

        <rdar://problem/3659587>: "when typing in Blot, bold style does not carry over to next line after pressing 'return'"

        Did some work to improve the insert newline command. The refinement is to insert the newline
        at the upstream position of the caret, ensuring that the newline takes on the 
        appropriate style, and does not let the caret "escape" from an element that is
        conferring style.

        Prep work for latest delegate API for dragging.  In addition, I also straightened out all
        the cases of DHTML setting a drag image or setting pasteboard data, and how that would
        override WebKit's default behavior (which follows how WinIE does things).

        Now, applying styles works across blocks. I did quite a bit
