42  * Any event that passes between layers MUST be one of these events. Tasks
43  * can use their own events internally, but a FUNDAMENTAL design issue is
44  * that global events MUST be one of these events defined below.

46  * The convention used is the the event name contains the layer that the
47  * event is going to.
