That just exchanges the dimensions of the object rectangle for the
position of its "visible" outline. It is still checking for
position/existence -- the existence of visible pixels.
The ability to check for the actual position of the object outline is a
newer addition; the original intersect function only looked at the
object rectangle. Likely the addition of the visible pixels parameter,
which is very useful, confuses the concept which is still purely positional.
