John Peterson a8dafb8dc5 OpenGL: 
1. Reorganized display settings
2. Let render to main window also have the internal resolution setting
3. Set render to main window as default setting, it's the most common and best option used by the best emulators
4. Changed screenshot to capture the internal picture, independent of whatever the window size may be
