+ Are GUI element instances kept anywhere? After GUI.Add* is called I think they're lost and destructed?
+ I should create a handle in C++ code and only release it once Destroy is called?
+   - Then when GUIBase is destroyed all its child elements will remain.
+     - Not if in destructor I call Destroy
+   - Instead, register each GUI element with parent GUIBase? Then in managed Destroy also unregister it
+      - This means I need to iterate recursively over all elements and their children
+      - Means I probably also need "GetNumChildren", and "GetChild" methods.
