+ *    that wants to know if user tapped anywhere on the screen could use this. 
+ *  - Derived: client can use the forward-pointer-events-to-gesture-helper
+ *    functionality by deriving from CGestureControl. Client has to create at 
+ *    least one visual that captures pointer events. This base class will 
+ *    receive the events and forward them to CGestureHelper.
+ * 
+ * The client can keep other widgets on top of this control, to allow them
+ * priority of capturing the pointer events.
