 To implement solid-aware ST_Distance and ST_Intersects we seem to need to
 add a not super large bit of logic:
 {{{
 distance = mindist_as_it_is(geom1, geom2);
 if (box1 &&& box2 and distance > 0)
 { /* check if we are completely inside */
 geom1, box1, geom2, box2 = swap_so_that_box1_is_inside_box2();
 if (not ST_IsSold(geom2))
     return distance;
 pt1 = take_any_point_in(geom1);
 if (raycast_count_hits_to_infinity_from_point(pt1, geom2) is odd)
     return 0
 else
     return distance;
 }
 }}}
 This way we can avoid the semantic change altogether.
