Ugly, but closer inspection reveals unimportant.. the other fields are
never used.

Anyway... looks like the polygon is being cast to a BoxType (picking up
the polygon's bounding box), being jiggled to the shape of a pad, then
tested for insidedness.

I couldn't spot anything wrong with the (admittedly strange) way the
IsPointInPad test works, so was thinking to check the polygon bounding
boxes next.
