LongPoint2DLike

Queries the overlap of this shape with a given LongPoint2D p. The point is considered to have a side length of 1!

Returns the orientation of the given point wrt this point, according to the following scheme:

5 4 6 +---+ 1 | 0 | 2 +---+ 9 8 10

Therefore the horizontal orientation can be extracted with _ & 3, and the vertical orientation with _ >> 2, where orientation is 0 for 'parallel', 1 for 'before' and '3' for 'after', so that if the orient is before or after, the sign can be retrieved via _ - 2

For example, if this is LongPoint2D(4, 4) and the query point is LongPoint2D(4, 5), the result is 12. If the query is LongPoint2D(0, 0), the result is 5, etc.
