/**
* This layout has (nearly) the same height for each column.
* The height of all columns is defined by the height of the channel column with the largest
* sum of panel heights. In all other columns space is added after each program to "stretch"
* the column to the same height.
*
* algorithm:
* <li> find the column with the largest height (using preferred size of panels)</li>
* <li> make all columns equally high, do this by adding the same amount of empty space
* at the end of each panel in a column
