The new structure for storing all the flags that concern the HUDLayer. I
couldn't come up with a better name, any ideas?

Is the macro CC_EXPORT necessary? I saw it used on structures like this.

+    HeadsUpDisplayLayerFlags();
+
+    bool showFPSCounter;
+    bool showPlatformLayerTree;
+
+    bool showPaintRects;
+    bool showPropertyChangedRects;
+    bool showSurfaceDamageRects;
+    bool showScreenSpaceRects;
+    bool showReplicaScreenSpaceRects;
+    bool showOccludingRects;
+    bool showNonOccludingRects;
+
+    bool showDebugInfo() const;
+    bool showDebugRects() const;
+};
+
 class HeadsUpDisplayLayer : public Layer {
 public:
     static scoped_refptr<HeadsUpDisplayLayer> create();

     virtual bool drawsContent() const OVERRIDE;
 
+    void setFlags(HeadsUpDisplayLayerFlags&);
+    const HeadsUpDisplayLayerFlags& flags() const { return m_flags; }
+
     void setFontAtlas(scoped_ptr<FontAtlas>);
     void setShowFPSCounter(bool);

     HeadsUpDisplayLayer();
