/*
  There are 4 types of things in X11: requests, replies, errors, and events.

  Each of them has a format defined by a small integer that defines
  the type of the thing.

  Requests have an opcode in the first byte.
  Events have a code in the first byte.
  Errors have a code in the second byte (the first byte is 0)
  Replies ...

  Replies have a sequence number in bytes 2 and 3.  The sequence
  number should be used to identify the request that was sent, and
  from that request we can determine the type of the reply.
