A texture one logical device has shared with the others over the same browser device.
This is the backend half of an exported texture (ExportedTextureBacking). The runtime keeps it for as long as an export token or a registration made from the export is alive, and the browser texture lives at least that long: the producer releasing its own identifier does not destroy a texture a share still holds, and the implementation lets the browser side go of it when this object is destroyed. Browser objects belong to the worker that obtained the device, so that release runs only on the thread that made the share: one destroyed elsewhere hands its release to that thread, which runs it the next time it yields to the browser. A share whose thread has exited goes with its browser device, which destroys every texture a share still holds when the last logical device over it is released.
