This hides the virtual destructor for SkOSWIndows, which you don't want to do.

Thanks,
Refactored into a tearDownBackend to use when we add the feature to change
backends during runtime.

+
+    // Changes the device type of the object.
+    void setupBackend(DeviceType type);
+
+    DeviceType getDeviceType() const { return fType; }
+
+protected:
+    // Your class should override this method to do its thing.
+    virtual void draw(SkCanvas* canvas) SK_OVERRIDE;
+
+    SkCanvas* createCanvas() SK_OVERRIDE;
+
+private:
+    DeviceType fType;

why two blank lines?

Corrected.

+    GrRenderTarget* fRenderTarget;
+    GrGLInterface* fInterface;
+    typedef SkOSWindow INHERITED;
