[swift-evolution] [Proposal]: Rectangles and other common structures.

I support this, not because I find NS- and CG- geometric structs confusing.
I support it because I'm hoping Swift library versions would be generic. I
would be very glad to see us get *Rect<Double>* or *Point<Int>* as part of
the standard library.
