/** 
 * Transmit a range of updated atoms from server to client.
 * This can be descriptions of entirely new atoms, or updates to existing atoms.
 * It more or less always uses the same format. Creation is simply a full update
 * of an atom that hasn't been sent yet.
 * 
 * The AtomDelta message will also include a viewport center, and a viewrange.
 * This will implicitly tell the client that it can forget about any objects outside this view range.
 * (We might yet go for a caching approach, where stuff outside the client's view is stored, such as turfs,
 *  but that would be implemented quite differently, that is via chunks)
