Arithmetic operators and utility functions for CGPoint, CGSize and CGRect.

Usage

Use arithmetic operators on CGPoint and CGSize, mixed with scalar values for multiplication and division:

let start = CGPoint(x: 5, y: 7)
let offset = CGPoint(x: 3, y: -2)
let result = start + offset * 2
//result is a CGPoint with x=11 and y=3

You can mix CGPoint and CGSize with all operators:

let result = CGPoint(x: 5, y: 7) + CGSize(x: 3, y: -2)
//result has the type of the operator's left hand side. CGPoint in this case.

Convert between CGPoint and CGSize:

let point = CGSize(width: 400, height: 300).point()
let size = CGPoint(x: 400, y: 300).size()

See the source code in CGExtensions.swift to learn about other functionality and conversions.
