I've just noticed what I thought was an oddity:

big  _ 100 at 100 corner: 200 at 200.
small _ 140 at 140 corner: 160 at 160.
big intersects: small	"true"

however, none of the sides of small answer true to intersectsLineFrom:to:

big intersectsLineFrom: small topLeft to: small topRight.	"false"
etc...

so what does "intersects" mean in this case?

Right now, if a Rectangle lies entirely inside another Rectangle, these are 
said to be intersecting.

However, if a line segment lies entirely inside a Rectangle, these are not 
said to be intersecting.

I just thought this was curious...
