// This file is about the layout (Preproess() and Group()) of the IPMI time line view.
// The layout happens according to the following sequence that is very similar to how
// the layout is done for DBus messages:
//
// 1. User clicks any of the checkboxes for the grouping fields (NetFN, CMD)
// 2. OnGroupByConditionChanged() is called
// 3. OnGroupByConditionChanged() calls PreProcess() and Group()
// 4. PreProcess() takes the IPMI messages extracted from the DBus capture
//    (g_ipmi_parsed_entries), and determines the start time.
// 5. Group() takes the IPMI messages, and the list of keys, and groups the messages
//    by the keys. The output is picked up by GenerateTimeLine(), which writes the
//    timeline data into the Intervals and Titles arrays. The draw loop immediately
//    picks up the updated Intervals and Titles arrays and draws on the canvas
//    accordingly.
