CAN_DIAGONAL_SMOOTH	Are two atoms border adjacent, takes a border object, something to compare against, and the direction between A and B Returns the way in which the first thing is adjacent to the second
BITMASK_FOUND	Check that non border objects use to smooth against border objects
BITMASK_ON_BORDER_CHECK	Returns true if the smooth is acceptable, FALSE otherwise
