A small and very specialized package to make working with CG[Size|Point|Vector]-esque wrappers of two floating-point numbers easier.

This package makes vectorized operations of the SIMD2 class available when working with the aforementioned CoreGraphics types.

In addition to the appropriate SIMD2 functions, Boole-ified comparison operators are included that return numeric versions of SIMDMask.

Situations where you want said types to behave more interoperably are simply too common to ignore. Consider for example, the following code from a WWDC slide:

let boundsSize: CGSize = /* ... */
var frameToCenter: CGRect = /* ... */

// center horizontally
if frameToCenter.size.width < boundsSize.width {
    frameToCenter.origin.x = (boundsSize.width - frameToCenter.size.width) / 2
} else {
    frameToCenter.origin.x = 0
}

// center vertically
if frameToCenter.size.height < boundsSize.height {
    frameToCenter.origin.y = (boundsSize.height - frameToCenter.size.height) / 2
} else {
    frameToCenter.origin.y = 0
}

With overloaded operators and Boole-ified comparison operators this code reduces to:

frameToCenter.origin = CGPoint.zero + (frameToCenter.size < boundsSize) * ((boundsSize - frameToCenter.size) / 2)

This package could be made more general but I'm limiting it for simplicity and compile-times.
