Resource: window_num

This resource is used to set the window number. This is a number greater than 0 that uniquely defines each WXPloop session.  This will create a message queue to allow the loopset program to communicate with the wxploop program.  

If the value is "-1", wxploop is put in batch mode (no message queue) and wxploop prints the window ID information to standard output.  If the window number is a filename, wxploop is put in batch mode and the window ID information is also written to the file.  The filename is then specified with the device resource "-de=w,,filename".
