You also have to fix distribution of window sizes so that in a layout like this:

  -----------------------------
  |               |           |
  |               |           |
  ----------------            |
  |         |     |           |
  |   1     | 2   |     3     |
  |         |     |           |
  -----------------------------

it is 1, 2 and 3 that gets the leftoer pixels. Handling split and delete of 
windows correctly can be hard.
