Yes, the scan stuff will definitely be input dependent. Good spotting,
this is a real bug (inherited from the VP3 codebase, looks like). There
are similar issues with some of the other search directions.
Has anyone else read this code? I'm a little unclear on why the bounds
check it does do can just wrap the buffer. Obviously the bounds check
needs to be fixed/augmented, but I'm not sure what it should in those
