- The first 4 fields in an event 'CCSL' are already unpacked in
expectReplyHeader. No need to get the L field again: it is already in the
'extra' variable.
- The new signature is:
createClient(options, initCB), where
- options is an optional object that defines different parameters such as
display, etc.
- initCB is an optional callback with the signature: function(err, display)
- The initCB is going to be called with an error ONLY if the connection to the X
server fails. Further errors in the server connection will be 'emitted'.
- Update tests and test-runner.js accordingly.
- Update README.
