-	/// <summary>
-	/// The Interface Class is the root of crow graphic trees. It is thread safe allowing
-	/// application to run multiple interfaces in different threads.
-	/// It provides the Dirty bitmap and zone of the interface to be drawn on screen.
-	/// </summary>
-	/// <remarks>
-	/// The Interface contains :
-	/// 	- rendering and layouting queues and logic.
-	/// 	- helpers to load XML interfaces files directely bound to this interface
-	/// 	- global static constants and variables of CROW
-	/// 	- Keyboard and Mouse logic
-	/// 	- the resulting bitmap of the interface
-	/// 
-	/// the master branch and the nuget package includes an OpenTK renderer which allows
-	/// the creation of multiple threaded interfaces.
-	/// 
-	/// If you intend to create another renderer (GDK, vulkan, etc) the minimal step is to
-	/// put an interface instance as member of your root object and call (optionally in another thread) the update function
-	/// at regular interval. Then you have to call
-	/// mouse, keyboard and resize functions of the interface when those events occurs in the host app.
-	/// 
-	/// The resulting surface (a byte array in the OpenTK renderer) is made available and protected with the
-	/// RenderMutex of the interface.
-	/// </remarks>
