        Fix for 4109667, sIFR flash replacement technique often malfunctions.  This bug occurs when the plugin
        widget update causes the onload for the document to fire.  Because you can be in the middle of a style
        recalc when doing an attach (in response to a stylesheet load), the onload fires in the middle of the attach
        process when the tree is in a bogus state.

        The fix is to add a bit to the document that tells style recalc that the implicitClose() method was invoked
        during the style recalc process and the code has been patched so that when this situation occurs, the close is
        deferred until after the style recalc has finished.

        When built without a build style (by Apple B&I) we want to get the target from the

        Xcode building. Now that this is fixed, you should not get a full rebuild if you switch
        from command line to Xcode or back.

        Experimental prototype of user-resizable textareas. All the new code is guarded by
        #if ALLOW_RESIZING_TEXTAREAS, which is false unless you remove a comment and rebuild.
        
        This code allows you to press near the bottom-right corner of any textarea and drag
        to resize the textarea on the page. It works correctly with textareas in left-aligned
        or centered blocks, but is weird in right-aligned blocks. It also does something
        sensible if the width is specified as a % (in that case, you can resize vertically only).
        The user-created-size survives resizing the window and survives the back/forward cache.
        It does not survive reloading the page.
        
        This complete-lack-of-affordance UI is obviously not shippable, but this proof of concept

        Loose ends:

            - need to test behavior of Windows IE with horizontal scroll wheeling; we currently send a distinct event
              for that relatively obscure case, which means the event handlers won't fire at all; might be incorrect
            - overflow scrolling is done after all DOM event handling, but ideally should be done in the overflowing
              element's default event handler; not important in practice
            - frame scrolling is done after all DOM event handling, but probably should be done in a default event handler;

        We clearly need a better solution to 4041374. We can't indiscriminately remove event listeners in closeURL() after-all. Since event listeners are registered in a <script> tag, which is evaluated and executed at page load time, this becomes a problem since we don't reevaluate a page's <script> that is in the back/forward cache.  Thus once you leave the page, the listeners are gone for good.  This is the problem.

        The problem is that a new case in the delete code did not consider when the
        downstream end node of the selection might be an ancestor of the upstream start
        node. That is the case in this bug. The downstream end is the body element, and
        this line of code would delete all the children of the downstream end:
            removeChildrenInRangePreservingPosition(m_downstreamEnd.node(), 0, 
                m_downstreamEnd.offset(), m_upstreamStart);

        The fix is to check for this "is ancestor" case, and do some tree logic to find
        the right offset of the downstream end node for the call to
        removeChildrenInRangePreservingPosition().

        * khtml/editing/htmlediting.cpp:

        for the relevant box, failure to add in the amount of float-avoidance will make the text at the coordinates
        greater than end-of-line minus float-avoidance ineligible for caret placement.

        keystrokes grouped together in a single undo operation. A change on 27 Jan in WebKit to change the way delete
        keystrokes are handled made this feature regress. Previous to that change, the backwards delete
        key went through separate code that is no longer in the tree that did not set the selection in the way
        it is done now.
        
        The solution is to add an extra argument to the set-selection call. The WebCoreBridge now offers this method:
        -[WebCore setSelectedDOMRange:range affinity:closeTyping:]. Now, callers must indicate whether setting the 
        selection will act to close typing or not.

        * kwq/WebCoreBridge.h: Changed header accordingly to change method shown below.
        * kwq/WebCoreBridge.mm:
        (-[WebCoreBridge setSelectedDOMRange:affinity:closeTyping:]): Added closeTyping argument to this method.

        <rdar://problem/4045513> Copying and pasting selection starting at end of paragraph can incorrectly remove line break

        The copy/paste code before this patch had no notion of a "logical newline" at the start of the selection. We have
        had a similar notion for "logical newline" at the end of the selection for quite some time. To fix these bugs, we

        I also tried to simply the code that sets the start position for inserting content to be pasted. I also improved a
        weakness in the smart-paste code. Now, we check before and after the paste for whether we need to add a leading or
        trailing space. The code previous to this patch only did a "before" check, with the result that we sometimes added
        a second space. In other words, the code did not realize that DOM changes done by pasting could cause formerly
        unrendered whitespace to become rendered. Also moved line placeholder clean up code to its own function.
        (khtml::ReplaceSelectionCommand::removeLinePlaceholderIfNeeded): New helper that further refines the notion

        Fixes <rdar://problem/4040848> "REGR: Sun security-check demo applet does not load". My earlier fix for 3603191 deferred loading the applet until the </applet> tag is reached, so all <param>s will be available. Unfortunately that meant that if the </applet> tag was missing, the applet would never load at all. So instead, the loading needs to happen when the ID_APPLET tag is popped from the parser stack for any reason.

        I've restored the old NodeImpl::closeRenderer() method. Except it's now virtual, with a no-op base implementation, and is overridden by HTMLAppletElementImpl, replacing its setAllParamsAvailable method that I added a few weeks ago when fixing 3603191.

        This ensures that the applet will get loaded even if there is no explicit </applet> tag.

        The changes to htmlparser.cpp back out my earlier change and restore the lines that were deleted on 8/3/04 when the old closeRenderer was removed.

        <rdar://problem/4024929> REGRESSION (Mail): Pasting text with multiple reply levels removes one level instead of all
        
        The code to figure out which node to use to merge into an existing line did not drill into the first inline element
        as needed to make the feature work as user expect. Instead, it looked at the first node, and if it was a block, it
        skipped that node. This worked for some cases (including the important "paste-as-quotation" case) but obviously 
        doesn't work for content quoted more than once.
        
        Now, mergeStartNode() will look for the first node in pasted content that is not a block. It will now also look
        for nodes specially marked by Mail as a node added to make "Paste As Quotation" work. It won't skip those. 
        
        NOTE: This change will break Mail's "Paste As Quotation" feature for TOT WebKit users, but this is only a temporary 
        problem that will exist until we sync up with Mail's pending change to mark nodes as needed in its pasteAsQuotation:

        Changed the few places where it matters to use a "collapsible whitespace" concept instead of
        the general whitespace concept. This means treating only ' ' and '\n' specially instead of

        <rdar://problem/4035648> REGRESSION (Mail): line feed in source HTML file causes bad copy/paste behavior

        The createMarkup() function in markup.cpp iterates over the nodes in a range,
        and does some bookkeeping to figure out when to add close tags to the markup.
        Some code added at the start of the loop to prevent markup from being written
        for unrendered nodes short-circuited the rest of the loop, and so prevented
        the close-tag-writing code from running when it should.

        This is why the "plain" text wound up inside of the bold tag in the example
        above. The addition of the unrendered return character caused an incorrect
        delay in the close tag for the bold element from being written out, with the
        result being that it wound up including additional content.

        The fix is to add checks for node renderers throughout the loop at the points
        where markup is written out for each node. This allows the additional close
        tag logic to run as needed.

        All layout tests pass with this change.

        <rdar://problem/4038267> REGRESSION (Mail): Crash copying and pasting end of paragraph

        Code to handle content that has a "logical" newline at the end of the pasted content, and the code
        to adjust the selection at the end of the paste operation made an assumption that at least one
        node had been inserted by the paste command. This is not necessarily true in the case where the sole content
        in the pasted content is one of these "logical" newlines. Adjust some code around so that we don't deref
        null, but still adjust the selection correctly for this case. In each of the two functions below, some
        null checks have been added, and some code has been rearranged a little bit to continue on through
        the end of completeHTMLReplacement, even if no nodes have been inserted. The patch looks bigger and more
        complicated than the conceptual change.

        <rdar://problem/4035198> Pasting text with different styles does not get reproducible results

        I had a good idea yesterday to improve the way we "fixup" styles after
        pasting, but i chose a poor data structure to do it, a map of
        nodes-to-styles. In the fixup step, I iterated over the map elements and
        did the fixup. However, since the order in which the items would come
        out of the map is indeterminate, we got unpredictable results.

        So, the concept was good, but the implementation was flawed. I have
        fixed this mapping to be a list instead, so the order that nodes are
        evaluated in the fixup step is document order. This works nicely.

        * khtml/editing/visible_position.cpp:
        (khtml::VisiblePosition::isCandidate): Insertion point disappearing was due to a failed
        check here after deleting all the content in the body element. The special "empty block"
        needs to add check for DOM children. A block may have straggling anonymous render children in
        some cases, and so the check needs to be (!DOM-kids || !render-kids).

        Also, I botched the last checkin trying to split these two patches in my tree. Wrong layout tests 
        got checked in, I checked in a conflict marker in the Changelog, etc. I fixed everything with this checkin.

        Improved fix for this bug:
        
        <rdar://problem/3996605> Insert paragraph command puts new block in wrong place, creating difficult-to-handle HTML

        Maciej and I discussed this situation at length, and we came up with a better fix than I did earlier.

        * khtml/editing/htmlediting.cpp:
        (khtml::InsertParagraphSeparatorCommand::doApply): Simplify one special case so that it only handles the 
        "last in block" situation. Remove special case for "downstream node is in different block" and handle
        this case with a little bit of special code in the general insertion case.

        Results studied to make sure there were no problems.
