137 - Initializes an EAGLView with 0-bit depth format, and RGB565 render buffer.
138 - The EAGLView view will have multiple touches disabled.
139 - It will create a UIWindow and it will assign it the 'window' variable. 'window' must be declared before calling this marcro.
140 - It will parent the EAGLView to the created window
141 - If the firmware >= 3.1 it will create a Display Link Director. Else it will create an NSTimer director.
142 - It will try to run at 60 FPS.
143 - The FPS won't be displayed.
144 - The orientation will be portrait.
145 - It will connect the director with the EAGLView.
146
147 IMPORTANT: If you want to use another type of render buffer (eg: RGBA8)
148 or if you want to use a 16-bit or 24-bit depth buffer, you should NOT
149 use this macro. Instead, you should create the EAGLView manually.
