- 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.
