why are both the constructor and this factory function public? with a public
factory i would expect the constructor to be private

Made the constructor private.

+ private:
+  // Overridden from PlatformViewport:
+  virtual void Init(const gfx::Rect& bounds) OVERRIDE;
+  virtual void Show() OVERRIDE;
+  virtual void Hide() OVERRIDE;
+  virtual void Close() OVERRIDE;

+  virtual void SetBounds(const gfx::Rect& bounds) OVERRIDE;
+  virtual void SetCapture() OVERRIDE;
+  virtual void ReleaseCapture() OVERRIDE;
+
+  Delegate* delegate_;
+  gfx::Rect bounds_;
+
+  DISALLOW_COPY_AND_ASSIGN(PlatformViewportHeadless);
+};
