I don't want another constructor that effectively duplicates the existing one.
I'm ok with this if you plan on going through and fixing all callers to the new
one. Is that your intention? Also, this should be explicit.

Yeah, I'll just add it to this CL. Only a couple of callers.

   ~ShadowBorder() override;
 
  protected:
   // Overridden from views::Border:
   void Paint(const views::View& view, gfx::Canvas* canvas) override;
   gfx::Insets GetInsets() const override;
   gfx::Size GetMinimumSize() const override;
 
  private:
-  // Blur amount of the shadow in pixels. For details on how blur is defined see
-  // comments for blur_ in class ShadowValue.
-  const int blur_;
-
-  // Shadow color.
-  const SkColor color_;
-
-  // Number of pixels to shift shadow to bottom.
-  const int vertical_offset_;
-
-  // Number of pixels to shift shadow to right.
-  const int horizontal_offset_;
+  // The shadow value to use for this border.
+  const gfx::ShadowValue shadow_value_;
 
   DISALLOW_COPY_AND_ASSIGN(ShadowBorder);
 };
