/** @def CC_DIRECTOR_INIT

- Initializes an EAGLView with 0-bit depth format, and RGB565 render buffer.

- The EAGLView view will have multiple touches disabled.

- It will create a UIWindow and it will assign it the 'window' variable. 'window' must be declared before calling this marcro.

- It will parent the EAGLView to the created window

- If the firmware >= 3.1 it will create a Display Link Director. Else it will create an NSTimer director.

- It will try to run at 60 FPS.

- The FPS won't be displayed.

- The orientation will be portrait.

- It will connect the director with the EAGLView.

 

 IMPORTANT: If you want to use another type of render buffer (eg: RGBA8)

 or if you want to use a 16-bit or 24-bit depth buffer, you should NOT

 use this macro. Instead, you should create the EAGLView manually.
