72 * one small (3 pixels?) representing the state of the process and the second
73 * type is thicker (10 pixels?) representing on which CPU a process is running

76 * Extremums of the lines :
77 * x_min : time of the last event context for this process kept in memory.
78 * x_max : time of the current event.
79 * y : middle of the process in the process list. The process is found in the
80 * list, therefore is it's position in pixels.
82 * The choice of lines'color is defined by the context of the last event for this
