 * Create a process list
 * contains the data for the process list
 * tells the height of the process list widget
 * provides methods to add/remove process from the list
 * 	note : the sync with drawing is left to the caller.
 * provides helper function to convert a process unique identifier to
 * 	pixels (in height).

 * //FIXME : connect the scrolled window adjustment with the list.
