Nit: remove this, it appears unused.

Actually, I think they are all needed here since there is references as function
arguments.

 struct WebPoint;
 
 class WebSubstringUtil {
 public:
     // Returns an autoreleased NSAttributedString that is the word under
-    // the given point, or nil on error.
+    // the given point inside the given WebFrameWidget or nil on error.
     // Upon return, |baselinePoint| is set to the left baseline point in
     // AppKit coordinates.
-    BLINK_EXPORT static NSAttributedString* attributedWordAtPoint(WebView*,
+    BLINK_EXPORT static NSAttributedString* attributedWordAtPoint(
+        WebFrameWidget*,
         WebPoint,
         WebPoint& baselinePoint);
 
     // Returns an autoreleased NSAttributedString that is a substring of the
     // Frame at the given range, or nil on error.
     BLINK_EXPORT static NSAttributedString* attributedSubstringInRange(WebLocalFrame*,
         size_t location,
         size_t length);
 
     // Returns an autoreleased NSAttributedString that is a substring of the
     // Frame at the given range, or nil on error.
     // It also gets the baseline point for the given range for showing
     // dictionary lookup bubble.
     BLINK_EXPORT static NSAttributedString* attributedSubstringInRange(WebLocalFrame*,
         size_t location,
         size_t length,
         WebPoint* baselinePoint);
 };
 
 } // namespace blink
