// Clients make requests of the annotator by providing an image "source ID"
// (which is either an image URL or hash of an image data URI) and an associated
// ImageProcessor (the interface through which the annotator can obtain image
// pixels if necessary).
//
// The annotator maintains a cache of previously-computed results, and will
// compute new results either by sending image URLs (for publicly-crawled
// images) or image pixels to the external server.
