// Revision 1.4  2006/01/08 05:04:50  fraggle
// Don't grab the mouse on the net waiting screen
//
// Revision 1.3  2006/01/07 20:08:11  fraggle
// Send player name and address in the waiting data packets.  Display these
// on the waiting screen, and improve the waiting screen appearance.
//
// Revision 1.2  2006/01/02 21:50:26  fraggle
// Restructure the waiting screen code.  Establish our own separate event
// loop while waiting for the game to start, to avoid affecting the original
// code too much.  Move some _gui variables to net_client.c.
//
// Revision 1.1  2005/12/30 18:58:22  fraggle
// Fix client code to correctly send reply to server on connection.
// Add "waiting screen" while waiting for the game to start.
// Hook in the new networking code into the main game code.
//
//
// Graphical stuff related to the networking code:
//
//  * The client waiting screen when we are waiting for the server to
//    start the game.
