// vncClient.cpp

// The per-client object.  This object takes care of all per-client stuff,
// such as socket input and buffering of updates.

// vncClient class handles the following functions:
// - Recieves requests from the connected client and
//   handles them
// - Handles incoming updates properly, using a vncBuffer
//   object to keep track of screen changes
// It uses a vncBuffer and is passed the vncDesktop and
// vncServer to communicate with.
