OPENGL: Implement aspect ratio support and toggling. Improve fullscreen switching. Fix cursor scaling bug.

Browse source 
Now the hotkey Ctrl-Alt-Enter will switch between all available fullscreen modes. Alt-Enter will only switch to the best mode available, and exit fullscreen mode if already on it.
The different aspect ratios can be switched with Ctrl-Alt-A. The normal mode will stretch the contents to the screen, while other modes will stretch only one dimension to the screen size, and maintain the aspect ratio for the other dimension.
