Disable title screen background movement

[Bumber]

There's an option to disable head bobbing while playing, but there doesn't seem to be a way to disable the swaying of the title screen panorama. It's somewhat nauseating to watch while waiting for a world to load, etc.

the paralax in the main menu does give me a slight feeling of vertigo, it would be quite nice to be able to turn it off, even if just for performance boost.
