        - fixed <rdar://problem/3790526> mark-related methods not implemented (needed for people with them in their key bindings files)

        * khtml/khtml_part.h: Added mark and setMark.
        * khtml/khtmlpart_p.h: Added m_mark.
        * khtml/khtml_part.cpp:
        (KHTMLPart::mark): Added.
        (KHTMLPart::setMark): Added.

        * kwq/KWQKHTMLPart.h: Change name of markedRange to markedTextRange to decrease
        the change it will be confused with the mark.
        * kwq/KWQKHTMLPart.mm:
        (KWQKHTMLPart::clear): Update for name change.
        (KWQKHTMLPart::markedTextRange): Ditto.
        (KWQKHTMLPart::setMarkedTextRange): Ditto.

        * khtml/rendering/render_text.cpp: (RenderText::paint): Update for name change.

        * kwq/WebCoreBridge.h: Remove setSelectionFrom, selectionStart, selectionStartOffset,
        selectionEnd, selectionEndOffset, and clearMarkedDOMRange. Renamed setMarkedDOMRange
        to setMarkedTextDOMRange and markedDOMRange to markedTextDOMRange. Added setMarkDOMRange
        and markDOMRange for the Emacs "mark".
        * kwq/WebCoreBridge.mm:
        (-[WebCoreBridge setMarkDOMRange:]): Added.
        (-[WebCoreBridge markDOMRange]): Added.
        (-[WebCoreBridge setMarkedTextDOMRange:]): Renamed.
        (-[WebCoreBridge markedTextDOMRange]): Renamed.

        * khtml/xml/dom_selection.cpp: (DOM::Selection::validate): Make paragraph positions
        canonical by using deep rendered positions. Maybe someday this won't be an ad hoc
        decision any more.

        * khtml/xml/dom_nodeimpl.cpp: (NodeBaseImpl::removeChildren): Use ref and deref
        rather than the unconventional check for 0 refCount. This makes us a bit more
        robust against a node going away partway through the removal process.

        * WebCore.pbproj/project.pbxproj: Update MACOSX_DEPLOYMENT_TARGET to 10.3.

        * WebKit.pbproj/project.pbxproj: Update MACOSX_DEPLOYMENT_TARGET to 10.3 and add -fobjc-exceptions
        so we can use new exceptions.

        * WebView.subproj/WebHTMLView.m:
        (-[WebHTMLView setMark:]): Added.
        (unionDOMRanges): Added.
        (-[WebHTMLView deleteToMark:]): Added.
        (-[WebHTMLView selectToMark:]): Added.
        (-[WebHTMLView swapWithMark:]): Added.
        (-[WebHTMLView markedRange]): Updated for change to bridge method names.
        (-[WebHTMLView hasMarkedText]): Ditto.
        (-[WebHTMLView unmarkText]): Ditto.
        (-[WebHTMLView _selectMarkedText]): Ditto.
        (-[WebHTMLView _selectRangeInMarkedText:]): Ditto.
        (-[WebHTMLView setMarkedText:selectedRange:]): Ditto.
        (-[WebHTMLView _insertText:selectInsertedText:]): Removed check for empty string. An empty string
        should not be filtered out here. We need to allow inserting an empty string.
        (-[WebHTMLView _selectionIsInsideMarkedText]): Updated for change to bridge method names.
        (-[WebHTMLView _updateSelectionForInputManager]): Ditto.

        * WebView.subproj/WebView.m: (-[WebView searchFor:direction:caseSensitive:wrap:]):
        Changed to use selectionDOMRange instead of selectionStart.

        * WebView.subproj/WebHTMLRepresentation.h: Removed unused setSelectionFrom method.
        * WebView.subproj/WebHTMLRepresentation.m: Ditto.
