Computes the area of the intersection between the two polygons.

Note: the area result has little more accuracy than a float
This is true even if the polygon is specified with doubles.

@param a Polygon A
@param b Polygon B
@return area of area of intersection. Negative if the order (CW vs CCW) do not match.
