+ * Hooks to be called by the main window *
+ *****************************************************************************/
+
+
+/* Event hooks are the drawing hooks called during traceset read. They draw the
+ * icons, text, lines and background color corresponding to the events read.
+ *
+ * Two hooks are used for drawing : before_schedchange and after_schedchange hooks. The
+ * before_schedchange is called before the state update that occurs with an event and
+ * the after_schedchange hook is called after this state update.
+ *
+ * The before_schedchange hooks fulfill the task of drawing the visible objects that
+ * corresponds to the data accumulated by the after_schedchange hook.
+ *
+ * The after_schedchange hook accumulates the data that need to be shown on the screen
+ * (items) into a queue. Then, the next before_schedchange hook will draw what that
+ * queue contains. That's the Right Way (TM) of drawing items on the screen,
+ * because we need to draw the background first (and then add icons, text, ...
+ * over it), but we only know the length of a background region once the state
+ * corresponding to it is over, which happens to be at the next before_schedchange
+ * hook.
+ *
+ * We also have a hook called at the end of a chunk to draw the information left
+ * undrawn in each process queue. We use the current time as end of
+ * line/background.
