Window layout

Dzen's window layout is as follows:

 ------------------------------------------
|        Title window, single line         |
`------------------------------------------´
|                                          |
|               scrollable                 |
|              Slave window                |
|             multiple lines               |
|     lines to display simultaneously      |
|           controlled with the            |
|              '-l' option                 |
|                                          |
|                                          |
`------------------------------------------´

The first line you provide to dzen always goes to the title window. All other consecutive lines will be drawn to the slave window unless you explicitly override this with the ^tw() command.
