        If there is no line wrapping, a caret can leave its containing block but it shouldn't leave its root line box
        
        Also added code to handle a caret wider than one pixel.
        
        Added fast/inline/25277.html and fast/inline/25277-2.html

        * rendering/RenderText.cpp:
        (WebCore::RenderText::localCaretRect): Distribute a caret's width to either side of the offset,
        so that a caret between two characters doesn't hang over one character more than the other.
        If there is no wrapping, the caret can leave its containing block, but not its root line box.
