	/**
	 * Determines if FaceRecognition can work with a givem image type. This is determined as
	 * intersection of types that are supported in Nextcloud and types that are supported in DLIB.
	 *
	 * Dlib support can be found here:
	 * https://github.com/davisking/dlib/blob/9b82f4b0f65a2152b4a4243c15709e5cb83f7044/dlib/image_loader/load_image.h#L21
	 *
	 * Note that Dlib supports these if it is compiled with them only! (with libjpeg, libpng...)
	 *
	 * Based on that and the fact that Nextcloud is superset of these, these are supported image types.
	 *
	 * @param string $mimeType MIME type to check if it supported
	 * @return true if MIME type is supported, false otherwise

The expression return false returns the type false which is incompatible with the documented return type true.
