An immutable, thread-safe token naming one texture of a producer device, for registration on another runtime device over the same backend device.
Produced by Device::exportTexture on the producer's thread and consumed by Device::registerTexture on the consumer's. Copies share one holder of the allocation: the texture's memory stays alive while any copy, or any registration made from one, is alive, even after the producer has released its handle. An empty token names nothing.
