A thin Swift wrapper around libvips. Work in progress...
// call once per app before using VIPS
try VIPS.start()
// load an image from a file, create a thumbnail and save to new file
try VIPSImage(fromFilePath: "my-example.jpg")
.thumbnailImage(width: 100, height: 100, crop: .attention)
.write(toFilePath: "my-example-cropped.jpg", quality: 80)
