Takes three points and returns whether they are in clockwise order or not
when looking from above (looking in direction 0,0,-1). If all the points
have the same x or y values then one cant tell (when looking from above) if it is clockwise
so in this case we look from front (looking in direction 0,0,-1) and if
that doesn't succeed we look from the right side (looking in direction 0,-1,0)
Returns YES or NO
Note that the three points create a plane and from each side of the plane
what is clockwise is exactly the other way around.
If you want to check if the points are clockwise from a given point
use STATE_math_get_plane_point_relations() like that
create a plane from the three points and call the function when the point
in which you look from is the given point.
