* Accelerate vImage Swift Overlays A suite of functions, enumerations, and option sets to make working with vImage in Swift simpler. * vImage_Buffer - new initializers to instantiate and initialize buffers with a single function call. * vImage_Buffer - new functions to copy buffers and create CGImage instances from contents. * vImage_CGImageFormat - new initializers. * vImage_CGImageFormat - new equivalence operator. * vImageConverter - methods to wrap free functions. * vImageConverter - new make and convert functions. * vImageCVImageFormat - new make functions. * vImageCVImageFormat - methods to wrap free functions. * vImage_Error - errorDescription function. * vImage flags as an option set. * Add new methods for generating CV -> CG and CG -> CV converters. * update comments: `height` and `width` to `size`. * `vImage_CGImageFormat.componentCount` should be `Int`. * `vImage_CGImageFormat.componentCount` should be `Int` * Move `self.init()` to after the size check for kvImageNoAllocate init. * Buffer initializers to width and height rather than size. * change vImage_CGImageFormat lightweight initializer to accept Int for `bitsPerComponent` and `bitsPerPixel`. * Flesh out docs for vImage_Buffer.size * Remove faux initializer in favor of new static function: `preferredAlignmentAndRowBytes`. * Change functions to use proper error handling rather than inout error codes. * Removed `flags` from basic init. The only real flag to pass here is print diagnostics to console, and I now throw proper errors. * Tests to check error throwing for buffer copy. * remove unnecessary import, add missing docs. * Add comments to error enums. * Fix bug creating string from format code. * Make `vImageCVImageFormat.formatCode` a `UInt32`. * Remove equivalence operator from `CGImageFormat`.
