TBD:
The IM for a MultiPolygon and a Polygon, in that order, that do intersect is
I ∩ I = 2, if the interiors overlap, else .false (Note this value cannot be 1 or 0.)
I ∩ B = 1, if the interior of one line segment of one Polygon is inside the second Polygon, else .false (Note this value cannot be 0.)
I ∩ E = 2, if the first Polygon is not a subset of the second Polygon, .else .false. (Note this value cannot be 1 or 0.)
B ∩ I = 1, if one line segment of the boundary of the first Polygon is inside the second Polygon, else .false (Note this value cannot be 0.)
B ∩ B = 1, if line segments from each Polygon overlap, else 0, if the boundaries of the Polygons touch at one or more points, else .false

If the order of the two geometries is reversed, the intersection matrix would be the transpose of the above.
