32 * This function basically draw lines and icons. Two types of lines are drawn :
33 * one small (3 pixels?) representing the state of the process and the second
34 * type is thicker (10 pixels?) representing on which CPU a process is running
35 * (and this only in running state).
37 * Extremums of the lines :
38 * x_min : time of the last event context for this process kept in memory.
39 * x_max : time of the current event.
40 * y : middle of the process in the process list. The process is found in the
41 * list, therefore is it's position in pixels.
43 * The choice of lines'color is defined by the context of the last event for this
