           Summary: move directionOfEnclosingBlock() to be global so that
                    it could be reused
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: HTML Editing
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: xji at chromium.org
            Blocks: 25298


we should provide a directionOfEnclosingBlock(Node*) so that it could be reused in SelectionController and other functions in visible_units.cpp, such as moving caret by word in visual order (which needs to know the direction of box and enclosing block, and the caret movement direction).
