详细描述

Scene3DTestScene designed for test 2D-3D mixed render for common 3D game usage.

Scene has three logic sub scenes:

World scene for maintain 3D game world objects, there are two cameras in this scene, one for skybox, another for other 3D models.
UI scene, the root scene, maintain a menu in main UI.
Dialog scene maintain two dialogs, which has 3D models on it and another 2D elements above on 3D models, there are three cameras for them.
OSD scene, maintain the UI element, like the description dialog, above
on other elements.
