Queries the overlap of this shape with a given
LongPoint2D p.
Queries the overlap of this shape with a given
LongPoint2D p. The point is considered to have
a side length of 1!
true if this shape contains or partly overlaps
the given point
Returns the orientation of the given point wrt this point, according to the following scheme:
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.
