/*

The first column always contains the window identity as a hexadecimal integer.

The second column always contains the desktop number (a -1 is used to identify a sticky window).

If the -p option is specified the next column will contain the PID for the window as a decimal integer.

If the -G option is specified then four integer columns will follow: x-offset, y-offset, width and height.

The next column always contains the client machine name.

The remainder of the line contains the window title (possibly with multiple spaces in the title).
