9 * This is a simple wrapper for strings representing http/https URLs. new URL() is an excessively expensive operation
10 * that may be unnecessary if the class loading the image from the URL doesn't actually require a URL object.
11 *
12 * Users wishing to replace the class for handling URLs must register a factory using GlideUrl.
