//  CVPixelBuffer+Rotate.swift
//
//  Abstract:
//  This CVPixelBuffer extension provides a method that will rotate an
//  ARGB pixel buffer by a multiple of 90 degrees using the high performance
//  Accelerate framework provided on Apple platforms. This method is
//  designed to be compatible with Core Video APIs on iOS, which may require
//  the pixel buffer to be memory aligned and backed by an IOSurface.
