        - fixed <rdar://problem/4123592> Can't resize textareas that have a width specified by a style

        * kwq/KWQTextArea.mm:
        (-[KWQTextArea getNumColumns:andNumRows:forSize:]):
        removed this method, which I had added earlier to set cols and rows correctly
        (-[KWQTextAreaTextView _trackResizeFromMouseDown:]):
        set width and height instead of cols and rows; handle the intrinsic margin that sometimes appears
        on form elements
