@brief Class that creates and handle the main Window and manages how
and when to execute the Scenes.
The CCDirector is also responsible for:
- initializing the OpenGL context
- setting the OpenGL pixel format (default on is RGB565)
- setting the OpenGL buffer depth (default one is 0-bit)
- setting the projection (default one is 3D)
- setting the orientation (default one is Protrait)
Since the CCDirector is a singleton, the standard way to use it is by calling:
_ CCDirector::sharedDirector()->methodName();
The CCDirector also sets the default OpenGL context:
- GL_TEXTURE_2D is enabled
- GL_VERTEX_ARRAY is enabled
- GL_COLOR_ARRAY is enabled
- GL_TEXTURE_COORD_ARRAY is enabled
