r4828
Add "Auto Aspect Ratio" to both graphics plugins. It's the new default, so you can forget about switching aspect manually from now on. In the Auto mode, aspect ratio is automatically set depending on whether it's a Wii or GC game, and whether the global Wii Widescreen setting has been set. There is still the possibility to override, which can be useful for the very few GC games that do support widescreen.
