* Use clearer pref names. * Default (and only support) IPDL dispatching. * Make DispatchCommands async-only. * Sync ipdl command per sync webgl entrypoint. * Eat the boilerplate cost, since there's not too many. * Run SerializedSize off same path as Serialize. * All shmem uploads go through normal DispatchCommands. * Defer pruning of dead code for now so we can iterate quickly. * Use Read/Write(begin,end) instead of (begin,size). * This would have prevented a bug where we read/wrote N*sizeof(T)*sizeof(T).
